Cautionary Statement:

Kin has concluded it has a reasonable basis for providing the forward-looking statements included in this announcement. The detailed reasons for that conclusion are outlined throughout this announcement and are disclosed Annexure 2 Table 1, Section 4. This announcement has been prepared in accordance with the JORC Code (2012) and ASX Listing Rules. The Company advises that the Definitive Feasibility Study (DFS) results, Mine Plan and Forecast Financial Information contained in this announcement are reasonable in nature as the conclusions are based on highlevel technical and economic assessments, and are sufficient to support the estimation of Probable Ore Reserves (92%) used in the Mine Plan and to provide an assurance of economic development at this stage.

The Company advises that while the DFS is based on Probable Ore Reserves, it is partly based on Inferred Mineral Resources (8%). There is a lower level of geological confidence associated with Inferred Mineral Resources and there is no certainty that further exploration work will result in the determination of Indicated Mineral Resources or that the Production Target itself will be realised. The stated production target is based on the company’s current expectations of future results or events and should not be solely relied upon by investors when making investment decisions. Further evaluation work is required to establish sufficient confidence that this target will be met. Currently the drill spacing in the Inferred portion of the resource is too wide to allow the material to be classified as Indicated. The Company believes that there is a good probability of conversion of Inferred Resources into Indicated Resources as the structures and geological units are now well understood.

EXECUTIVE SUMMARY AND INTRODUCTION

Kin Mining NL ( “Kin” or “Company” ) (ASX:KIN) is pleased to announce the completion of the Definitive Feasibility Study (DFS) for the Company’s 100% owned Leonora Gold Project (LGP) in the North-Eastern goldfields of Western Australia. The LGP contains Indicated and Inferred Resources of 22.3 Mt @ 1.4 g/t gold for 1.02Moz of contained gold (see Table 4). The DFS has delivered a robust forecast outcome for the Company. The LGP will generate strong free cash flows underpinned by a low capex pathway to cash flow. The DFS confirmed the LGP as a technically sound and highly profitable project.

Development is based on three open pit mining centres (Mertondale, Cardinia and Raeside) which will supply a 1.5Mtpa conventional CIL processing plant centrally located at Cardinia. The feasibility study has delivered a Maiden Ore Reserve of 373koz (7.9Mt @ 1.5g/t) . Kin has secured ownership of the Lawlers Processing Facility, supported by the option to purchase a 2.5MW ball mill providing the capacity to treat up to 1.5Mtpa on oxide and transition ores. The pre-production capital cost is $35.4M which includes 18% in contingencies. By scheduling the mining of the high margin and low strip ratio open pits first, the pre-production capital is repaid in just 11 months. The project has an initial mine life of 7 years, with considerable exploration upside.

The DFS provides a LOM operating cash cost (C1) of A$957/oz. and an All-In-Sustaining Cost (AISC) of A$1,038/oz. for the life of the project. The LGP delivers a discounted NPV8% of A$107.4M (before corporate costs and tax) and an Internal Rate of Return (IRR) of 77%. The forecast LOM revenue is $596.1M with a projected operating cash-flow surplus of $167.9M based on a gold price of A$1,600/oz. An estimated 8.6Mt at 1.5g/t (405koz) will be mined and processed, delivering 372koz of recovered gold.

Significant potential remains to grow the LGP mineral resources via exploration of known targets which present near-mine extensional opportunities within the project area.

Kin Managing Director Don Harper said,

“the DFS clearly demonstrates the technical and economic strengths of the Leonora Gold Project and this solid foundation provides Kin with the opportunity to build a significant new Australian gold production company.

The DFS has concluded that the LGP will enjoy low pre-production and operating costs which underpin a low-risk, high-margin gold operation with a short payback period and strong free cash flow.

Kin is now on a clear pathway to cash flow and plans to be producing gold in the second half of 2018 in the heart of one of WA’s richest gold-mining districts.

The company will continue to undertake an aggressive exploration strategy at the LGP seeking to expand resources by initially drilling recently discovered high grade primary gold targets.

On behalf of the Board we thank our staff, contractors, consultants and advisors for their most diligent efforts in completing a very detailed and comprehensive DFS”.

ORE RESERVE

In conjunction with the DFS, Kin has completed a maiden Ore Reserve estimate for the LGP based on the 2017 Mineral Resources estimated by independent consultants Carras Mining ( see ASX announcement 30 August 2017 ). The Ore Reserve is supported by the DFS and has been completed by independent mining consultants Entech Pty Ltd (Entech).

A detailed financial model for the LGP was generated as part of the DFS process which has been used by Entech to determine the economic viability of the Ore Reserve estimate.

The Ore Reserve (see Table 2) has been completed in accordance with the JORC Code (2012). The Probable Ore Reserve is based on the Indicated portion of the Mineral Resource (see Table 4). It should be noted that none of the Inferred portion of the Mineral Resource has been incorporated into the Probable Ore Reserve.

Table 2 presents a summary of the Probable Ore Reserve based on the open pits being optimised at a A$1,575/oz. gold price. Refer to Section 4 of JORC Code (2012) Table 1 (Annexure 2, Appendix E) for full details on the Ore Reserve.

PROJECT SUMMARY

The Leonora Gold Project is located 30km north-east of Leonora, and approximately 250km north of the main regional town of Kalgoorlie, Western Australia (see Figure 1). The area is well serviced by infrastructure including a network of high quality roads, an airstrip at Leonora with regular services to Perth and close to an established mining supply network.

A Pre-Feasibility Study (PFS) was completed on 15 December 2016 which formed the basis on which the DFS was developed. The DFS investigated the potential economic viability of the LGP based on the mining and on-site treatment of Mertondale, Cardinia and Raeside Mineral Resources. The Mineral Resources on which the DFS is based are located on granted Mining Leases.

Independent JORC Code (2012) estimates of the Mineral Resources at the LGP total 22.3Mt @ 1.4g/t for 1.02Moz of contained gold ( see ASX Announcement 30 August 2017 ). The DFS includes the mining and processing of 8.6Mt @ 1.5g/t gold for 372koz of recovered gold over a 7-year mine life.

In 2017, the Company secured the decommissioned 800,000tpa Lawlers processing plant and associated infrastructure owned by Gold Fields which is located approximately 160km to the north northwest of the LGP. The DFS incorporates the refurbishment and upgrade of the Lawlers plant to 1.5Mtpa through the installation of a refurbished 2.5MW ball mill and six new 1,500m[3] CIL tanks. The proposed plant incorporates a two-stage crushing circuit feeding the 2.5MW ball mill, with gold extracted by gravity and CIL processes. The Lawlers processing plant is in good condition and comes with a large inventory of spares and infrastructure. The electrical componentry is particularly valuable having been substantially upgraded by Barrick shortly before the operation was acquired by Gold Fields. The DFS contemplates relocation of the Lawlers plant and infrastructure to the centrally located Cardinia mining centre with construction and commissioning expected to take 11 months.

Early mining operations will be mainly focused at the Cardinia area. Pre-production mining costs will be low with the first open pit deposit Kyte, exhibiting a very low strip ratio of only 2:1 waste to ore. The production ramp up schedule is based on a conservative mill throughput of 25% (month 1), 50% (month 2), 75% (month 3) and 100% in month 4. Mining operations will include Mertondale pits in year 3 and Raeside material in year 4.

Existing accommodation infrastructure facilities in Leonora will be expanded to house a permanent workforce of approximately 64 people who will be employed on a Fly-In-Fly-Out (FIFO) arrangement.

Operating costs have been estimated to ±15%. The DFS has determined the LGP can produce an initial 61koz in its first full year of production and reaching a maximum production of 65koz in year 7. The LOM AISC operating costs estimate for the LGP is estimated at $1,038/oz. Preproduction capital is expected to be repaid within 11 months from the successful commissioning of the process plant.

The pre-production capital cost is estimated at $35.4M. LOM capital cost is estimated at $41.4M (Table 6) which includes the pre-production capital and subsequent lifts to the TSF, borefield establishment and construction of haul roads. In anticipation of exploration success, the Company expects the LGP to continue well beyond its 7-year mine life and has not allocated closure costs to the financial model.

GEOLOGY

Gold deposits in the LGP production area are hosted by a series of shear zones that cut through a typical Eastern Goldfields greenstone sequence. Three Mining Centres, namely Mertondale, Cardinia, and Raeside, are recognised within the project, which have slightly different geology and structural setting (See Figure 1).

The Mertondale prospects extend over a total 12km strike length from Merton’s Reward in the south to Mertondale 5 (32,000oz mined in 1991) 10km to the north. Merton’s Reward (60,524oz previously mined), Mertondale 2 (2,700oz mined in 1987 and 2010) and Mertondale 3-4 (179,300oz mined between 1986-1993) are contained within the eastern branch of the Mertondale Shear Zone and extend over approximately 3km of strike. Quicksilver, Tonto, Eclipse and Mertondale 5 are all contained within the western branch of the shear zone and extend over approximately 9km of strike. The Mertondale area consists of a central felsic volcanic sequence bounded on either side by a tholeiitic basalt-dolerite-carbonaceous shale +/- felsic porphyry sequence. The western and eastern shear zone branches are generally located near the felsic volcanics/mafic contacts. Merton’s Reward, Mertondale 3-4 and Tonto are included in the Ore Reserve estimate.

The Cardinia prospects overlie a sequence of intermediate-mafic and felsic volcanic lithologies and locally derived epiclastic sediments. Minor felsic porphyries and lamprophyre lithologies have been recognised within and adjacent to the Bruno and Lewis areas. At Lewis, these intrusive rocks are often associated with mafic-felsic contacts. The eastern edge of the BrunoLewis system is intruded by a dolerite sill. At Helens and Rangoon, the gold mineralisation is hosted within sheared zones of metabasalt, and minor sediment. Kin recently announced the discovery of two primary zones of mineralisation at Lewis and Helens.

Mineralisation within the Raeside prospect is hosted by a mixed package of fine- grained sediments and a quartz dolerite unit. The dolerite is sill-like in nature, and roughly conforms to observed bedding trends. The dolerite is fine to medium grained with extensive chlorite alteration. The gold mineralisation is generally stratiform within the dolerite and certain sedimentary horizons.

MINERAL RESOURCES

The LGP has a total of 22.3Mt @ 1.4 g/t for 1.02Moz gold in Mineral Resources to JORC Code (2012) standard (Table 4), all within a 25km radius of the proposed centrally located Cardinia process plant. Of this total, 75% or 17Mt @ 1.4 g/t gold for 771koz is in the Indicated Mineral Resource category and 25% is in the Inferred Resource category.

OVERALL MINING STRATEGY

  • The DFS assumes the open pit mines at Mertondale, Cardinia and Raeside (see Figure 1) will deliver ore to a conventional purpose-built Carbon-In-Leach (CIL) gold treatment facility centrally located at Cardinia. Kin envisages that all mining will be undertaken by owner miner operators using equipment supplied and maintained by a contract mining equipment supplier. All drill, blast and grade control activities will be undertaken by contractors. All technical and managerial direction will be by Kin.

Mining operations will operate on a continuous 12-hour shift basis. Kin personnel and contract mining personnel will be accommodated in the nearby township of Leonora and it is expected that the mining and processing workforce will operate on the same roster based on 14 work shifts followed by seven rostered days off (2 weeks on: 1 week off).

The mining strategy is focused on initially delivering oxide and transitional ore sourced primarily from the Cardinia deposits. Harder material from Merton’s Reward will be blended with the softer oxide and transitional ores in the latter stages of the project. Waste material from the open pits will be deposited on surface waste dumps.

The LGP DFS contemplates the co-development of three open pit mining centres, namely:

  • Cardinia (mainly oxide and transitional), which comprises the Bruno-Lewis Link, Lewis, Kyte, Helens and Rangoon deposits;

  • The Mertondale area, which comprises the Mertons Reward (transitional & fresh), Mertondale 3_4 (oxide, transitional & fresh ores) and Tonto (transitional ore); and

  • The Raeside deposits of Michelangelo and Leonardo (transitional and fresh ores)

Detailed open-pit mine designs were completed on all deposits in the mine plan. Mining operations are based on mining a maximum of 3 deposits at any one time. This allows effective management of the mining fleet, drill & blast activities, and grade control. The o p e n pit optimisations were based on both Indicated and Inferred Mineral Resources at a gold price of A$1,575/oz. Mine designs and development of the mining and milling schedules for the DFS have been completed by Entech.

The LOM gold production in the DFS includes 92% Ore Reserve ounces and 8% Inferred ounces (see Table 5). The Inferred Mineral Resources in the DFS have had the required modifying factors applied (see Annexure 2, Appendix E). Inferred material was mined as part of the usual mining cycle but stockpiled separately. The Inferred material was then scheduled for processing in month 42 post plant commissioning allowing the first 3.5 years of gold production to be based on 100% Ore Reserve.

Pre-production activities include construction of the processing plant, mining fleet mobilisation, site set up, clearing, grubbing, stockpiling of topsoils, preparation of the ROM pad, construction of the first stage of the tailings dam embankment, and installation of a water supply pipeline to convey water from the existing Mertondale 3-4 open pit to the processing plant.

Reverse Circulation (RC) grade control drilling will be undertaken on an 8m by 8m grid pattern to 20m depth at 60-degree angles. Trenching is planned at the Bruno Lewis Link / Lewis deposits to ensure confidence in the dig block boundaries within the supergene oxide zone before mining of the benches.

The open pit mining methods are well known and widely used in the local mining industry. Open pit vertical development rates were planned to adhere to industry standards. Designs have focused on maximising gold recovery from the optimised Whittle shells whilst targeting low strip ratios. The optimum and most profitable outcome was to design single lane pits with passing bays and a 1:10 gradient suitable for a 100t haulage fleet. Based on the Bruno (2010) and Lewis trial mining (2016) pits, free digging of material to a depth 25-30m should be

achievable for all oxide and a large portion of the transition material.

Drill and blast activities will be carried out from surface on 5m benches and then excavated in 2.5 m passes. A 5% drill and blast estimate has been assumed for oxide, 60% for transition material and 100% for fresh material.

Ore will be hauled in 100 tonne trucks directly from the mining area and dumped onto the ROM pad into various graded stockpiles. Ore will be rehandled from the graded stockpiles on the ROM pad by a front-end loader (FEL) and fed to the primary crushing plant to meet the nominated processing blend. Ore from Mertondale and Raeside will be trucked from local mining centre intermediate ROM’s to the ROM at Cardinia using road trains.

GEOTECHNICAL

Geotechnical assessments for the DFS were completed by Perth based independent consultants, Peter O’Bryan & Associates. The assessments used the evaluation of existing pits at Mertondale (1991-2010), the Bruno pit (2010) and the Lewis Trial pit (2016). The derivation of the proposed geotechnical open pit design parameters was predominantly based on new test work from diamond drilling activities and televiewer geotechnical data evaluation.

WATER SUPPLY

Process water supply for the LGP processing plant is planned to be drawn initially from water contained within the existing Mertondale 3-4 and Mertondale 5 open pits which includes groundwater recharge as water levels are lowered by pumping. A 20km water supply pipeline is planned to be constructed from Mertondale 3-4 to the Cardinia mill. Upon dewatering the Mertondale 3-4 pit the pipeline will be extended a further 10km to the Mertondale 5 pit to the north. There are seven known historical production bores that will feed into the main water supply line, however for the first 6 months of operations water will be supplied from Mertondale 3-4 and Mertondale 5 until the seven bores are refurbished and re-equipped to supply the mill. Fresh water supply will be generated via a reverse osmosis unit acquired as part of the Lawlers infrastructure acquisition at the plant.

HYDROGEOLOGY

Modelling assessments predict that a dewatering rate of about 20 l/s will be required to dewater Tonto and Mertondale 3-4 new pits during mining. The Cardinia mining region is likely to require average individual pit dewatering rates of 4-11 l/s, with peak individual years of up to 17 l/s. Based on the Eastern Borefield’s response to long-term pumping, the proposed Michelangelo-Leonardo pits will require dewatering and are likely to yield >30 l/s, Dewatering strategies have been developed and costed in the DFS.

1.5MTPA PROCESSING PLANT

In 2017, Kin acquired the Lawlers’ processing facility and associated infrastructure from Gold Fields Ltd for A$2.5M based on a $100,000 deposit followed by two equal payments for the balance. The first payment of A$1.2M was made on 8 September 2017 with the second due on 8 September 2018.

The Lawlers’ plant, which has been on care and maintenance for 27 months, has a capacity of approximately 800,000tpa. The plant includes a significant inventory of spare parts as well as laboratory, warehouse, administration buildings, plant design and construction drawings with the latter significantly reducing engineering costs and time.

Lawlers remains on care & maintenance with the mills rotated regularly. They have been completely stripped and cleaned internally, as have all gravity traps throughout the circuit. The gravity circuit tower is the only area where corrosion needs to be addressed via refurbishment after its move to the LGP, otherwise all equipment is in good order due to the excellent quality of the process water at Lawlers.

Kin has also secured an option to purchase a used 2.5MW ANI-Ruwolt ball mill in good condition from Macca-Interquip ( see ASX release dated 1 August 2017 ). The installation of the 2.5MW ball mill at the LGP is expected to provide sufficient single-stage primary grinding power to increase milling capacity to 1.5Mtpa for the softer oxide/transition ores. Six new 1500m[3] Carbon-In-Leach (CIL) tanks will be constructed to support the increased treatment rate.

The process plant general arrangement at Cardinia is shown in Figure 6.

Process Design Flowsheet

The process flow diagram for the 1.5Mtpa processing plant is illustrated in Figure 7. All main elements that comprise the processing plant are typical of conventional CIL plants operating throughout the Western Australian Goldfields. The LGP treatment circuit has been designed to produce a grind P80 75 µm and minimum leach retention time of 24 hours.

METALLURGY

Head analysis results for 26 composite ore samples prepared for metallurgical testing showed relatively small average variations in assay gold grade and interval calculated gold grade. Concentrations of arsenic in several samples, indicate the potential for mild refractory behavior of some fresh ore zones at Mertons Reward and Lewis.

Gravity and Cyanide Leach Recovery

Overall gravity recoveries range from 6.9% to 41.1% with an average gold recovery of 17.3%. The Lawlers gravity circuit has been incorporated in the LGP plant design to affect the recovery of the gravity gold component.

An average grind size of P80 125 µm is sufficient for the oxide ore composites tested, with a high average oxide ore gravity-leach recovery of between 95%-98%. Fresh ore lithology was mainly grind sensitive, requiring a P80 75 µm grind, resulting in average 24-hour recoveries of 88% and 85% for transitional and fresh lithology types respectively at Mertons Reward. Average fresh ore recovery over the 4 Helens pits was 93%. Transitional ore types observed a trend of reducing leach recovery with increasing antimony feed grade.

TAILINGS STORAGE FACILITY (TSF)

The TSF design concept features an above-ground impoundment with a single perimeter embankment. The maximum embankment height is 10.6 m and the total landform height at Life of Mine (LOM) is predicted to be RL 429.8 m, 14.8 m above ground level. The TSF classifies as Category 2, having a maximum embankment height below 15m and hazard rating of “medium”. The facility is designed to be unlined as it is expected that percolation rates from thickened tailings is low as there is less pore water available to seep into the ground. Independent consultants SRK, conducted a site investigation with the objective of determining foundation conditions for the TSF, identifying borrow materials in the area and investigating features of the terrain such as creeks and rock outcrops. Samples from potential borrow material were tested and a physical tailings characterisation conducted as part of this investigation. Tailings testing included rheological testing.

16

The thickened tailings concept was selected for DFS level design. Central tailings deposition (CTD) is the preferred deposition option as it minimises embankment construction volumes, allows staged development and maximises water return. A reduction of approximately 25% in embankment volume over a conventional upstream paddock facility was realised.

The TSF embankment will comprise mass clayey fill sourced from within the TSF footprint supplemented with overburden from the Bruno waste dump. Geotechnical investigations have confirmed the availability of suitable clayey construction materials for the TSF footprint and embankment. As indicated in the 2016 PFS (ASX announcement 15 December 2016), there remains significant opportunity to deliver tailings into mined out pits in the future, which would result in further reducing TSF capital expenditure.

POWER SUPPLY

Power will be supplied and operated by a contractor who will install a power station on site consisting of six 1250 kVA containerised diesel generating sets requiring only a level ground surface with good drainage. Kin will use four 1250kVA diesel generator sets for base load power, with two backup units to provide power for mill start-ups, additional power under the peak load conditions and to provide standby power to the mine.

ROADS, TRANSPORT & ACCOMMODATION

The national road between mining centre Kalgoorlie and Leonora forms the backbone of all road transportation in the area. Access to the LGP from the town of Leonora is via the sealed Leonora – Laverton road and a well-maintained private road to Cardinia. A capital cost has been allocated for the construction of a new 10km gravel haul road between Mertons Reward and the proposed Cardinia mill. The DFS has assumed that the existing Leonora all-weather airstrip will be used. A commercial charter will transport employees and contractors.

Single person village accommodation will be provided in the township Leonora. It is proposed to upgrade existing accommodation to include an additional 64 rooms. The workforce will be able to share existing recreational and messing facilities. Full messing and laundry services will be provided on a daily manday rate. An estimated 10% of the workforce is assumed to be employed locally and reside in the township of Leonora. There is sufficient overflow accommodation in Leonora available to cater for the overlap with construction, mining, and processing personnel during the commissioning phase.

PERMITTING & ENVIRONMENTAL

Kin holds all the tenure that the LGP requires for execution of its activities. All mining areas and infrastructure areas are on existing granted mining leases. All studies to support the lodgment of the required approvals have been completed. Kin have used a range of consultants best suited to provide the following studies:

  • Flora and fauna surveys completed across all project areas

  • Soil and waste characterisation and management

  • Subterranean field survey and lab assessments

  • Surface hydrology

  • Hydrogeology assessments

  • Proposed plant site sterilisation drilling

  • Refreshed discussions with participants of previous ethnographic surveys

There have been no issues identified in these studies that are expected to delay the submission and approval of the required consents.

Kin reached agreement with the regulators (DMIRS and DWER) to conduct a phased approval process to allow the processing plant to commence construction earlier than would have been

17

possible if it had to wait for final project mining parameters. The two-phased approach enables immediate commencement of construction of the process plant once a decision to mine is made and funding is secured, while providing the required time to further clarify the final project layout for Phase 2.

The Phase 1 approvals relate to the construction of the LGP processing plant and related infrastructure to dry commissioning in advance of the lodgement of complete operational approvals in Phase 2 for the mining and processing activities.

Phase 1 Approvals

A Mining Proposal been lodged with the Department of Mines, Industry Regulation and Safety (DMIRS) and a Works Approval has been lodged with the Department of Water and Environmental Regulation (DWER) ( see ASX announcement 17 August 2017 ).

Phase 2 Approvals

With the final outlines of the LGP project (final disturbance outlines) now completed Kin can prepare the final impact calculations and lodge the Phase 2 Mining Proposal, Clearing Permit and Works Approval to the relevant agency. Kin is not aware of any matter that would cause these approvals to be delayed.

HERITAGE

There are no active Native Title claims over the operational area. Former Native Title claimants over the area have been consulted and this resulted in heritage surveys being conducted over areas potentially impacted by a project development with no adverse findings. While some of the permits are yet to be received (or applied for) there are reasonable grounds this will not negatively impact the development timetable for the project.

CAPITAL COSTS

Kin and its specialist consultants have derived the processing capital cost estimate (± 15% nominal accuracy) to provide current costs suitable for use in assessing the economics of the project and to provide the initial estimates of capital expenditure. The estimated LOM project capital cost is $41.4. million, inclusive of $6.2 million of contingencies as summarised in Table 6.

The processing capital expenditure has had a third-party review by independent consultants SRK and found to be of a reasonable basis. The processing capital cost estimate is based upon a contractor quotation (Como Engineering) to dismantle and relocate the Lawlers plant to Cardinia, combination of specialist contractors and an owner build approach. Plant construction drawings are available and the estimate has been prepared to a level equivalent to that of ±15 accuracy.

Capital costs do not include a mining fleet as the DFS is based on a contractor equipment supplied and maintained basis or sustaining capital that are included in AISC (see Table 7).

Table 7. LOM Capital Cost Estimate Summary

CAPITAL COSTS
Finalpayment to Gold Fields Ltd for Lawlers ProcessingPlant Acquisition(September 2018) $1.2M
Relocate, Refurbish and Upgrade Lawlers ProcessingPlant to 1.5Mtpa $23.4M

Personnel, First Fill & Spares)
$2.6M
Contingency+17% $6.2M
TOTAL CAPITAL(LOM) $41.4M

Totals vary due to rounding.

OPERATING COSTS

The key operating cost elements assumed have been based on the Request for Quotation (RFQ) from various suppliers, mine employment consultants and drill & blast contractors. The RFQ received were within an accuracy of ±15% to meet the requirements for the DFS. Kin calculated the processing operating costs based on different material types and test work.

DFS costs were estimated from first principles and metallurgical laboratory test work for reagent consumption data and pilot plant scale trials from Bruno Pit (2010) and Lewis Trial Pit (2016) to assist in validating the operating cost model. The combination of soft oxide material and transition material in the production profile, low reagent consumption, high throughput rates and high oxide and transitional metallurgical recovery resulted in a low process operating cost on a per ounce basis. The LOM the average AISC is A$1,038 (±15% nominal accuracy). The operating costs over the LOM is summarised in Table 8.

Table 8. Operating LOM Cost Estimate

Item LOM Cost (A$M) LOM Cost/Ore t LOM Cost/oz.
Mining $180.9 $20.93 $486
Processing and Maintenance $158.0 $18.27 $424
General & Administration $17.8 $2.06 $48
Refining Charges $0.3 $0.04 $1

Sustaining Capital Costs $3.5 $0.40 $9
Total $386.7 $44.57 $1,038

Totals vary due to rounding.

ECONOMIC EVALUATION & SENSITIVITY

The financial assessment is based on A$1,600/oz gold price ( T a b l e 8 ) .

Using a base case gold price of A$1,600/oz (US$1,250/oz and an FX of 78c) and an 8% discount rate, the project generates an NPV of A$107.4M, an IRR of 77% with a payback period of approximately 11 months from first gold pour. The project is viable and robust at a wide range of gold price scenarios. Table 9 provides a sensitivity analysis demonstrating the forecast economics under a range of future gold prices scenarios.

PROJECT FINANCE

The financing required to construct and commission the LGP is an estimated A$35.4 million. Kin intends to finance the construction of the LGP infrastructure and the mine establishment costs for the open pit operations through a combination of project debt and equity. The Company will take a measured approach in setting the level of debt whilst minimising shareholder dilution. Preparations for the project debt financing have been advanced in the September 2017 quarter with the appointment of the financier’s independent technical consultant SRK. SRK have completed due diligent reviews on the Mineral Resource estimation, process capital, processing operating costs and metallurgy.

ESTIMATED TIME TO PRODUCTION

The DFS estimates potential gold production to commence in the second half of CY2018. This estimate assumes a 11-month construction and commissioning period. It is assumed that financing for the required capital will continue through CY2017. All statutory approvals are expected to be granted to allow the development to proceed as planned.

GOING FORWARD

Subject to receiving acceptable terms to finance the LGP the immediate milestones are:

  • Recruit management and operational personnel for the LGP.

  • Identify additional cost-saving measures from proposed capital and operating expenditure.

  • Maintain an aggressive exploration campaign focused on discovering high grade mineralisation.

RISKS & OPPORTUNITIES

Key risks identified during the DFS work include, but are not limited to:

  • Access to project funding.

  • Timely project approvals from government authorities.

  • Adverse movements in the Australian gold price.

  • Adverse movements in USD:AUD exchange rates.

  • Not achieving the mining production rates, dilution assumptions and metallurgical recovery rates.

  • Adverse movement in fuel price.

Key opportunities identified during the DFS work include, but are not limited to:

  • Achieving higher throughput and production rates by installing the Lawlers 600kw ball mill. (This eventuality has been assumed in the current plant layout).

  • High grade exploration success.

  • Drilling from the pit floor of Mertondale 3-4 (historical production 1.3Mt @ 4.3 g/t Au) once dewatered to access exposed high-grade material.

  • Conversion of inferred resources of 119koz. in Eclipse, Quicksilver, Krang and Forgotten Four (see Table 4) to mineable material.

Criteria Commentary
Sampling
techniques
All sample data, subject of this report and used for resource estimation work, is obtained from
various drilling programs carried at Mertondale out since 1981. Data was obtained predominantly
from Reverse Circulation (‘RC’) drilling, and to a lesser extent, diamond core (‘Diamond’ or ‘DD’)

Companies involved in the collection of the majority of the exploration data prior to 2014 include:
Nickelore NL (“Nickelore”) 1981‐1982; Hunter Resources Ltd (“Hunter”) 1984‐1988; Harbour
Lights Mining Ltd (a joint owned company of Ashton Gold WA Ltd and Carr Boyd Minerals Pty Ltd
‐ “HLML”) 1988‐1993; Mining Project Investors Pty Ltd (“MPI”) 1993‐1996; Sons of Gwalia Ltd

Kin Mining Ltd (“KIN”) acquired the Mertondale Project in 2014.
HISTORIC SAMPLING (1981‐2014)
Drill samples were generally obtained from 1m downhole intervals and riffle split to obtain a 3‐
4kg representative sub‐sample, which were submitted to a number of commercial laboratories
for a variety of sample preparations methods, including oven drying (90‐110°C), crushing (‐2mm
to ‐6mm), pulverizing (‐75μm to ‐105μm), and generally riffle split to obtain a 30, 40 or 50 gram
catchweight for gold analysis, predominantly by Fire Assay fusion, with AAS finish. On occasions,
initial assaying have been carried out using Aqua Regia digest and AAS/ICP finish, with anomalous
samples re‐assayed by Fire Assay fusion and AAS/ICP finish.
Diamond Drilling
Half core (or quarter core) sample intervals varied from 0.15 to 1.46m, but were predominantly
taken over 1m intervals, or at geological contacts, whichever was least. The remaining core was
retained in marked core trays and stored in a secure yard for future reference. The only known
available drill core from these programs and stored at KIN’s Leonora Exploration Yard, are those
drilled by Navigator.
RC Drilling
The vast majority of Reverse Circulation (RC) drill samples were collected over 1m downhole
intervals from beneath a cyclone and then riffle split to obtain a sub‐sample (typically 3‐4kg).
After splitting, 1m sub‐samples were typically collected in pre‐numbered calico bags, and the 1m
sample rejects were commonly stored at the drill site in marked plastic bags, for future reference.
First pass sampling often involved collecting composite samples by using a scoop (dry samples)
or spear (wet samples) to obtain 3m or 4m composited intervals, with the single metre split sub‐
samples being retained at the drill site. If the composite sample assays returned anomalous
results, the single metre sub‐samples for the anomalous composite intervals were retrieved and
submitted for analysis.
Navigator obtained sub‐samples from wet samples using the spear method.
Data relating to historical wet samples is not available, however the number of wet samples
involved is considered to be relatively low, and not material.
There are no sample rejects available from RC drilling prior to 2014. Most drill sites have been
rehabilitated and the sample bags removed and destroyed.

Criteria Commentary
Aircore Drilling
The procedures for sampling of Aircore drilling is generally the same as for RC drilling, although
in earlier (pre‐2004) programs, the majority of the 1m samples were mostly stored directly on the
ground prior to sampling with a scoop. Assay results from these samples are not used for resource
estimation work, however they do sometimes provide a guide in interpreting geology and
mineralisation continuity.
When drilling under dry conditions, Aircore samples should be of a comparable quality to RC
samples, when implementing same sampling techniques. Aircore sample assay results were only
used for resource estimation work if the 1m sub‐samples were obtained by riffle splitting of the
primary sample, prior to placing on the ground.
There are no sample rejects available from AC drilling prior to 2014. Most drill sites have been
rehabilitated and the sample bags removed and destroyed.
RAB Drilling
Sample returns from Rotary Air Blast (RAB) drilling are collected from the annulus between the
open hole and drill rods, using a stuffing box and cyclone. Samples are usually collected at 1 metre
intervals and placed on the ground with 3‐4kg sub‐samples collected using a scoop or spear. Up‐
hole contamination of the sample is commonplace, therefore this type of drilling and sampling is
regarded as reconnaissance in nature and the samples indicative of geology and mineralisation.
The qualities of samples are not appropriate for resource estimation work and are only
sometimes used as a guide for interpreting geology and mineralisation.
KIN MINING (2014‐2017)
Diamond drilling
Diamond drill core (HQ3) samples collected for analysis were longitudinally cut in half, and then
in quarters, using a powered diamond core saw blade centered over a cradle holding the core in
place. Half core (or quarter core) sample intervals varied from 0.3 to 1.11m, but were
predominantly taken over 1m intervals, or at geological contacts, whichever was least. The
remaining core was retained in their respective core trays and securely stored in KIN’s yard in
Leonora for future reference.
RC drilling
During drilling, sample return is passed through a cyclone and stored in a sample collection box.
At the end of each metre, the cyclone underflow is closed off, the underside of the sample box is
opened and the sample passed down through a riffle splitter.
All RC sub‐samples were collected over one metre downhole intervals and averaged 3‐4kg.
Sample reject from the riffle splitter were retained and stored in marked plastic bags, and located
near to each drillhole collar.
All drilling, sample collection and sampling handling procedures were conducted and/or
supervised by KIN geology personnel to today’s industry standards. QA/QC procedures were
implemented during each drilling program to industry standards.
Analysis
Once received at the assay laboratory, diamond core and RC samples were oven dried (105‐
110°C), crushed (‐6mm and ‐2mm), pulverised (P85% ‐75μm) and split to obtain a representative
50 gram sample catchweight for gold only analysis using Fire Assay fusion with AAS finish.
COMMENT
For some earlier (pre‐2004) drilling programs, RC and Aircore samples were obtained at 1.5 or 3
metre downhole intervals and a substantial portion of the historical MPI holes were composite
sampled over 2‐4m intervals.
For resource estimation work, Diamond, RC and some Aircore drilling data was used where
appropriate. RAB drillingdata was not used for resource estimation but was sometimes used as

an interpretative guide only. A proportion of the 1.5m sample intervals, particularly for Mertons
Reward, were used in the resource estimation, only where the sampling methods are
appropriate, and where they sit within the mineralisation interpretations.

HISTORIC DRILLING (1981‐2014)
Diamond Drilling
Diamond drilling was carried out using industry standard ‘Q’ wireline techniques, with the core
retrieved from the inner tubes and placed in core trays. Core sizes include NQ/NQ3 (Ø 45‐48mm),
HQ/HQ3 (Ø 61‐64mm), minimal NDBGM (Ø 50‐51mm) and some PQ/PQ3 (Ø 83‐85mm). At the
end of each core run, the driller placed core blocks in the tray, marked with hole number and
depth. Core recovery was usually measured for each core run and recorded onto the geologist’s
drill logs.
RC Drilling
RC drilling used conventional reverse circulation drilling techniques, utilising a cross‐over sub,
until the late 1980s, when the majority of drilling companies started changing over to using face‐
sampling hammers with bit shrouds. Drill bit sizes typically ranged between 110‐140mm. Samples
obtained from conventional RC drilling techniques with cross‐over subs often suffered from down
hole contamination (e.g. smearing of grades), especially beneath the water table. Samples
obtained from RC drilling techniques using the face sampling hammer suffered less from down
hole contamination and were more likely to be kept dry beneath the water table, particularly if
auxiliary and booster air compressors were used. These samples are considered to be more
reliable and representative.
Aircore Drilling
Aircore drilling is a form of RC drilling, but generally utilizing smaller rigs and smaller air
compressors, compared to standard RC drill rigs of the times. Aircore bits are hollow in the centre,
with the kerf comprising cutting blades or ‘wings’ with tungsten‐carbide inserts. Drill bit
diameters usually range between 75‐110mm.
The vast majority of Aircore drilling (98%) was conducted by Navigator utilising suitable rigs with
appropriate compressors (eg 250psi/600cfm). Aircore holes were drilled mostly into the
weathered regolith using ‘blade’ or ‘wing’ bits, until the bit was unable to penetrate further
(‘blade refusal’), often near to the fresh rock interface. Hammer bits were used only when it was
deemed necessary to penetrate harder rock types. Holes were typically no deeper than 60
metres.
RAB Drilling
RAB drilling is carried out using small air compressors (eg 250psi/600cfm) and drill rods fitted with
a percussion hammer or blade bit, with the sample return collected at the drillhole collar using a
stuffingbox and cyclone collection techniques. Drillhole sizesgenerallyrange between 75‐

29

Criteria Commentary
110mm.
KIN MINING (2014‐2017)
Diamond Drilling
Diamond drilling was carried out by contractor Orbit Drilling Pty Ltd (“Orbit Drilling”) with a truck‐
mounted Hydco 1200H drill rig, using industry standard ‘Q’ wireline techniques. Drill core is
retrieved from the inner tubes and placed in plastic core trays and each core run depth recorded
onto core marker blocks and placed at the end of each run in the tray.
Drillhole deviation was measured at regular downhole intervals, typically at 10m from surface,
thence every 30m to bottom of hole, using electronic multi‐shot downhole survey tools (e.g.
Reflex EZ‐TRAC, Camteq Proshot), or in some instances a separate independent program of
downhole deviation surveying was carried out to validate previous surveys, utilizing an electronic
continuous logging survey tool (AusLog A698 deviation tool).
Core orientation was obtained for each core run where possible, using electronic core orientation
tools (e.g. Reflex EZ‐ORI) and the ‘bottom of core’ marked accordingly.
RC Drilling
RC drilling was carried out by Orbit Drilling’s truck‐mounted Hydco 350RC drill rigs with
350psi/1250cfm air compressor, with auxiliary and booster air compressors (when required).
Drilling utilised mostly downhole face‐sampling hammer bits (Ø 140mm), with occasional use of
blade bits for highly oxidized and soft formations. The majority of drilling retrieved dry samples,
with the occasional use of the auxiliary and booster air compressors beneath the water table, to
maintain dry sample return as much as possible.
Drillhole deviations were surveyed downhole, during drilling operations, using an electronic
multi‐shot downhole tool (e.g. Reflex EZ‐TRAC). In some instances, drillholes were surveyed later
in open hole. Where stopes and cavities were encountered, surveying was completed within the
steel rods to obtain dip only readings. In the later drilling programs, downhole surveying was
carried out inside a non‐magnetic stainless steel (s/s) rod, located above the hammer. Providing
the tool was located in the middle of the stainless steel rod, azimuth and dip readings were
successfully recorded. A separate independent program of downhole deviation surveying was
carried out to validate previous surveys, utilizing an electronic continuous logging survey tool
(AusLog A698 deviation tool).

Criteria Commentary
COMMENT
The drilling database supplied includes depths of some RC precollars for diamond drillholes, but
is incomplete. Historical reports indicate that drill core sizes were predominantly HQ/HQ3 or
NQ/NQ3, with minimal PQ/PQ3, however database details are incomplete. Most historical
reports recorded core recoveries, although these details are not included in the database. Review
of some historical reports indicate that core recoveries were generally good, although recoveries
were typically less in highly fractured zones and some highly weathered mineralised zones in the
transition and oxide zones, however this information is not recorded in the supplied database.
RC drilling is the dominant drill type at all sites. RC drilling information is generally described in
varying detail in historical reports to the DMP, including drilling companies used and drilling rig
types, however it’s not all recorded in the database supplied. Review of the historical reports
indicates that reputable drilling companies were typically contracted and the equipment supplied
was of an acceptable standard for those times. During the 1990s, and 2000s, suitable large drill
rigs with on‐board compressors were probably complimented with auxiliary and booster air
compressors for drilling to greater depths and/or when groundwater was encountered. KIN’s
drilling was conducted with modern rigs equipped with auxiliary and booster compressors and
face sampling hammers with bit diameters typically 140mm.
When drilling under dry conditions, Aircore samples should be of a comparable quality to RC
samples, when implementing same sampling techniques. Aircore drilling data was only used in
resource estimation work, where the in‐field and laboratory sampling methodologies was
considered appropriate and limited to a number of selected Navigator drillholes.
Drill sample
recovery
HISTORIC DRILLING (1981‐2014)
Diamond drilling
Core recovery has been recorded in most drill logs for most of the diamond drilling programs
since 1981, but is not recorded in the supplied database. A review of some historical reports
indicates that generally core recovery was good with lesser recoveries recorded in zones of
broken ground and/or areas of mineralisation. Overall recoveries are considered acceptable for
resource estimation.
RC drilling
There is limited information recorded for sample recoveries for historical RC and Aircore drilling.
However there has been an improvement in sample recoveries and reliability following the
introduction of face sampling hammers and improved drilling technologies and equipment, since
the mid‐1980s.
KIN MINING (2014‐2017)
Diamond Drilling
Core recovery was recorded for each run by measuring total length of core retrieved against the
downhole interval actually drilled.
Diamond core recoveries were recorded in the database, and averaged 100%. Independent field
reviews by the Competent Persons (SC and GP) in 2017 of the diamond drilling rig in operation
and core integrity at the drill sites, demonstrated that diamond drill core recoveries were being
maximised by the driller, and that core recoveries were consistently > 95%, even when difficult
ground conditions were being encountered.
RC drilling
Integrity of each one metre RC sample is preserved as best as possible. At the end of each 1 metre
downhole interval, the driller stops advancing the rods, retracts from the bottom of hole, and
waits for the sample to clear from the bottom of the hole through to the sample collector box
fitted beneath the cyclone. The sample is then released from the sample collector box and passed
through the 3‐tiered riffle splitter fitted beneath the sample box. Sample reject is collected in
plastic bags, and a 3‐4kg sub‐sample is collected in pre‐marked calico bags for analysis. Once the
samples have been collected,the cyclone,sample collector box and riffle splitter are flushed with

Criteria Commentary
compressed air, and the riffle splitter cleaned by the off‐sider using a compressed air hose, and if
necessary a scraper. This process is maintained throughout the entire drilling program to
maximise drill sample recovery and to maintain a highly representative level of the material being
drilled.
RC drill sample recoveries are not recorded in the supplied database, however a review by the
Competent Person (GP) in May 2017 of RC drill samples stored in the field, and observations of
the two RC drilling rigs in operation, suggests that RC sample recoveries were mostly consistent
and very good, with the samples themselves being reliable and representative of the material
being drilled.
COMMENT
Due to the lack of detailed information in the database regarding historic (pre‐2014) Aircore and
RC drilling, no quantitative or semi‐quantitative impression of sample recovery or sample quality
is available. It's assumed to be satisfactory given that several deposits were mined in the past,
by open pit methods, in the Mertondale area (i.e. Mertondale 2, Mertondale 3‐4 and Mertondale
5), where the open pits were mined to their original design limits, based on the historical drill
data. This suggests that the amount of metal recovered was probably not grossly different from
pre‐mining drill data based expectations.
During Navigators drill programs wet samples were spear sampled instead of riffle split. This is
regarded as poor sampling procedure and these samples are regarded as unreliable however the
total number of wet samples is considered to be very low.
No indication of sample bias is evident nor has it been established. That is, no relationship has
been observed to exist between sample recovery and grade.
The amount of Aircore drilling data used in the Mertondale resource estimation process is
minimal and regarded as not material.
Logging HISTORIC DRILLING (1981‐2014)
The logging data coded in the database uses at least four different lithological code systems, a
legacy of numerous past operators (Hunter, MPI, SOG and Navigator). Correlation between codes
is difficult to establish, however it can be achieved with effort. Based on historical reports, drill
hole logging procedures appear consistent with normal industry practices of the time.
Navigator’s procedure for logging of diamond core included firstly marking of the bottom of the
core (for successful core orientations), core recovery, fractures per metre and RQD, lithology,
alteration, texture, mineralisation, weathering, and other features, and then marked up for
cutting and sampling. Several diamond drillholes were completed for geotechnical purposes and
were independently logged for structural data by geotechnical consultants. All diamond drill core
has been photographed, and currently stored at KIN’s yard in Leonora.
Navigator RC and Aircore logging was entered on a metre by metre basis, recording lithology,
alteration, texture, mineralisation, weathering and other features. The information was entered
directly into hand held digital data loggers and transferred directly to the database, after
validation, to minimize data entry errors.
The entire length of all drillholes is logged in full from surface to bottom of hole.
Logging is qualitative on visual recordings of lithology, oxidation, colour, texture and grain size.
Logging of mineralogy, mineralisation and veining is quantitative.
Drill core photographs are only available for Navigator’s diamond drillholes.
KIN MINING (2014‐2017)
KIN’s logging of drill samples was carried out in the field (RC drilling) or at the Leonora Yard
(diamond core) and entered onto a portable computer, on a metre by metre basis for RC, and by
sample intervals and/or geological contacts for diamond core. Data recorded included lithology,
alteration, structure, texture, mineralisation, sulphide content, weathering and other features.
Drillhole collar coordinates,azimuth,dip,depth and samplingintervals are also recorded in the

32

Criteria Commentary
drill logs in the field.
KIN geological personnel retrieved the core trays from the drill rig site and relocated them to
KIN’s yard in Leonora at the end of each day. Drill core was photographed in the field or at the
Leonora yard, prior to cutting using a diamond core saw to obtain quarter core samples for
analysis.
All information collected was entered directly into laptop computers or tablets, and transferred
to the database to be validated.
COMMENT
KIN has attempted to validate historical logging data and to standardize the logging code system
by incorporating the SOG and Navigator logging codes into one. This is an ongoing process and is
not yet completed.
The level of logging detail is considered appropriate for exploration and to support appropriate
mineral resource estimation, mining studies and metallurgical studies.
Qualitative logging includes classification and description of lithology, weathering, oxidation,
colour, texture and grain size. Quantitative logging includes identification and percentages of
mineralogy, sulphides, mineralisation, veining, and in addition, logging of diamond drilling
included geotechnical data, RQD and core recoveries.
For the majority of historical drilling (pre‐2004), and all of the more recent drilling, the entire
length of drillholes have been logged from surface to ‘end of hole’. Diamond core logging is
typically logged in more detail compared to RC and Aircore drilling.
Sub‐
sampling
techniques
and sample
preparation
HISTORIC DRILLING (1981‐2014)
Historical reports for drilling programs prior to 2004, are not always complete in the description
of sub‐sampling techniques, sample preparation and quality control protocols.
Diamond drilling
Diamond drill core (NQ/NQ3, HQ/HQ3 or PQ/PQ3) samples collected for analysis were
longitudinally cut in half, and occasionally in quarters for the larger (HQ/HQ3 or PQ/PQ3)
diameter holes, using a powered diamond core saw blade centered over a cradle holding the core
in place.
Half core (or quarter core) sample intervals varied from 0.15 to 1.46m, but were predominantly
taken over 1m intervals, or at geological contacts, whichever was least. The remaining half
(quarter) core was retained in core trays.
Where historical reports do not describe the sampling protocol for sampling of drill core, it is
assumed that drill core was sampled as described above.
RC drilling
Prior to 1996, limited historical information indicates most RC sampling was conducted by
collecting 1m samples from beneath a cyclone and passing through a riffle splitter to obtain a 3‐
4kg sub‐sample for analysis. RC sampling procedures are believed to be consistent with the
normal industry practices at the time. The vast majority of samples were dry and riffle split,
however spear or tube sampling techniques were used for wet samples.
Samples obtained from conventional RC drilling techniques with cross‐over subs often suffered
from down hole contamination, especially beneath the water table. Samples obtained from RC
drilling techniques using the face sampling hammer suffered less from down hole contamination
and were more likely to be kept dry beneath the water table, particularly if auxiliary and booster
air compressors were used. These samples are considered to be representative.
The vast majority of Reverse Circulation (RC) drill samples were collected at 1m downhole
intervals from beneath a cyclone and then riffle split to obtain a sub‐sample (typically 3‐4kg).
After splitting, 1m sub‐samples were typically collected in pre‐numbered calico bags, and the 1m
sample rejects were commonly stored at the drill site in marked plastic bags, for future reference.

or spear/tube (wet samples) to obtain 3m or 4m composited intervals, with the single metre split
sub‐samples being retained at the drill site. If the composite sample assays returned anomalous
results, the single metre sub‐samples for the anomalous composite intervals were retrieved and
submitted for analysis.
Navigator obtained sub‐samples from wet samples using the spear or tube method.
Data relating to historical wet samples is not available, however the number of wet samples
involved is considered to be relatively low, and not material.
There are no sample rejects available from RC drilling prior to 2014. Most drill sites have been
rehabilitated and the sample bags removed and destroyed.
Navigator included standards and blanks within each drill sample batch, at a ratio of 1 for every
20 samples, with the number of standards being inserted at a ratio of 1 for every 50 samples.
Since 2009, Navigator adopted a stricter sampling regime with the additional submission of field
split duplicate samples at a rate of 1 for every 50 primary samples.
Aircore drilling
The procedures for sampling of Aircore drilling is generally the same as for RC drilling, although
in earlier (pre‐2004) programs, the majority of the 1m samples were mostly stored directly on the
ground prior to sampling with a scoop.
Navigator included standards and blanks within each drill sample batch, at a ratio of 1 for every
20 samples, with the number of standards being inserted at a ratio of 1 for every 50 samples.
Since 2009, Navigator adopted a stricter sampling regime with the submission of field split
duplicate samples at a rate of 1 for every 50 primary samples.
A variety of laboratories were used for analysis. Prior to 2009, duplicate samples were not
routinely collected and submitted from RC and Aircore drilling to the same laboratory
consequently overall sampling and assay precision levels can’t be quantified for that period.
While QC protocols were not always comprehensive, the results indicate that assay results from
Navigators exploration programs were reliable. Results from pre‐Navigator operators are
regarded as consistent with normal industry practices of the time.
KIN MINING (2014‐2017)
Diamond drilling
Diamond drill core samples (HQ3) collected for analysis were longitudinally cut in half and
quarters, using a powered diamond core saw blade centered over a cradle holding the core in
place. Core sample intervals varied from 0.3 to 1.11m, but were predominantly taken over 1m
intervals, or at geological contacts, whichever was least. The remaining core was retained in their
respective core trays and stored in KIN’s yard for future reference.
At the time of resource estimation, assays had not yet been received for KIN’s diamond core
samples.
RC drilling
All RC sub‐samples were collected over 1 metre downhole intervals and retained in pre‐marked
calico bags, after passing through a cyclone and riffle splitter configuration. The majority of RC
sub‐samples consistently averaged 3‐4kg. Sample reject from the riffle splitter were retained and
stored in plastic bags, and located near each drillhole site. When drilling beneath the water table,
the majority of sample returns were kept dry by the use of the auxiliary and booster air
compressors. Very few wet samples were collected through the riffle splitter, and the small
number is not considered material.
Field duplicates were taken at regular intervals at a ratio of 1:50 and assay results indicate that
there is reasonable analytical repeatability, considering the presence of nuggety gold.

Quality of

and

tests
Numerous assay laboratories and various sample preparation and assay techniques have been
used since 1981. Historical reporting and descriptions of laboratory sample preparation, assaying
procedures, and quality control protocols for the samples from the various drilling programs are
variable in their descriptions and completeness.
HISTORIC DRILLING (1981‐2014)
For assay data obtained prior to 1996, the incomplete nature of the data results could not be
accurately quantified in terms of the data derived from the combinations of various laboratories
and analytical methodologies.
Since 1996, the majority of samples submitted to the various laboratories were typically prepared
for analysis firstly by oven drying, crushing and pulverizing to a nominal 85% passing 75µm.
In the initial exploration stages, Aqua Regia digest with AAS/ICP finish, was generally used as a
first pass detection method, with follow up analysis by Fire Assay fusion and AAS/ICP finish. This
was a common practice at the time. Mineralised intervals were subsequently Fire Assayed (using
30, 40 or 50 gram catchweights) with AAS/ICP finish.
Approximately 15‐20% of the sampled Aircore holes may have been subject to Aqua Regia digest
methods only, however Aircore samples were obtained predominantly within the oxide profile,
where aqua regia results are not expected to be significantly different to results from fire assay
methods.
In 1989, Hunter tabulated significant RC oxide zone intercepts from Merton’s Reward and
Mertondale 3‐4, and recorded average grades for both Aqua Regia (AR) and Fire Assay (FA),
confirming that there was no significant bias between AR/AAS and FA techniques. Length
weighted grades were almost identical for 800m of aggregate intercepts suggesting very low risk
of bias associated with the portion of utilised Aqua Regia results.
Hunter also carried out a comparison of 18 assays results in 1985, between standard fire assay
and screen fire assay results from five RC holes. There was a reasonably good correlation between
assays for the two methods for values < 5ppm Au, considering the presence of nuggety gold.
During 2004‐2014, Navigator utilised six different commercial laboratories during their drilling
programs, however Kalgoorlie Assay Laboratories conducted the majority of assaying for
diamond, RC and Aircore samples using Fire Assay fusion on 40 gram catchweights and AAS/ICP
finish.
Navigator regularly included, Certified Reference Material (CRM) standards and blanks with their
sample batch submissions to the laboratories at average ratio of 1 in every 20 samples. Sample
assay repeatability, and blank and CRM standards assay results are within acceptable limits. Since
2009, Navigator adopted a stricter sampling regime with the submission of field split duplicate
samples at a rate of 1 for every 50 primary samples.
KIN MINING (2014‐2017)
Sample analysis was conducted by SGS Australia Pty Ltd’s (“SGS”) Kalgoorlie and Perth
laboratories. Sample preparation included oven drying (105°C), crushing (‐6mm), pulverising
(P85% ‐75µm) and riffle split to obtain a 50 gram catchweight. Analysis for gold only was carried
out by Fire Assay fusion technique with AAS finish (SGS Lab Code FAA505).
KIN regularly insert blanks, field duplicate and CRM standards in each sample batch at a ratio of
1:20. This allows for at least one blank and one CRM standard to be included in each of the
laboratory’s fire assay batch of 50 samples. Field duplicate sample assay repeatability, blank
standards and CRM standards assay results are within acceptable limits for this style of gold
mineralisation.
SGS include blanks and CRMS aspart of their internalQA/QC for samplepreparation and analysis,

as well as regular assay repeats. Sample pulp assay repeatability, and internal blank and CRM
standards assay results are within acceptable limits.
COMMENT
The nature and quality of the historical assaying and laboratory procedures used are considered
to be satisfactory and appropriate for use in mineral resource estimations.
Fire Assay fusion or Aqua Regia digestion techniques were conducted on diamond, RC and Aircore
samples, with AAS or ICP finish.
Fire Assay fusion is considered to be a total extraction technique. The majority of assay data used
for the mineral resource estimations were obtained by the Fire Assay technique with AAS or ICP
finish. AAS and ICP methods of detection are both considered to be suitable and appropriate
methods of detection.
Aqua Regia is considered a partial extraction technique, where gold encapsulated in refractory
sulphides or some silicate minerals may not be fully dissolved, resulting in partial reporting of
gold content.
No other analysis techniques have been used to determine gold assays.
KIN’s ongoing QA/QC monitoring program identified one particular CRM that was returning
spurious results. Further analysis demonstrated that the standard was compromised and
subsequently removed and destroyed. A replacement CRM of similar grade was substituted into
the QA/QC program.
Verification

Verification of sampling and assaying techniques and results prior to 2004 has limitations due to
the legacy of the involvement of various companies, personnel, drilling equipment, sampling
protocols and analytical techniques at different laboratories, over a twenty year period.
During 2009, a selection of significant intersections had been verified by Navigator’s company
geologists and an independent consultant McDonald Speijers (“MS”). MS were able to validate
92% of the assay records in 50 randomly selected check holes, and only 6 assay discrepancies
were detected (< 0.2%), only 2 of those were considered significant. MS concluded that the very
small proportion of discrepancies indicated that the assay database was probably reliable at that
time.
Since 2014, significant drill intersections have been verified by KIN’s company geologists during
the course of the drilling programs.
During 2017, Carras Mining Pty Ltd ("CM") carried out an independent data verification. 8,991
assay records for KIN’s 2014‐2017 drilling programs were verified by comparing laboratory assay
reports against the database. 3 errors were found, which are not considered material and which
represents less than 0.01% of all database records verified for KIN’s 2014‐2017 drilling programs.
COMMENT
There is always a risk with legacy data that sampling or assaying biases may exist between results
from different drilling programs due to differing sampling protocols, different laboratories and
different analytical techniques.
Repeated examinations of historic reports on phases of diamond, RC and Aircore drilling have
been conducted from time to time. Assay results from KIN’s recent drilling are consistent with
surrounding information and as a result the information obtained from the various diamond, RC
and Aircore drilling programs (where sampling protocols are appropriate) have been accepted.
Recent (2014‐2017) RC and diamond drilling by KIN included some twinning of historical drillholes
in several locations predominantly within the Mertondale 3‐4 resource area. There is no material
difference observed between historical drilling information and the KIN drilling information. In
the areas that were not drilled with twin holes, the drill density is considered sufficiently close
enough to enable comparison with surrounding historic information, and there is no material
difference of a negative nature between historical drilling information and the KIN drilling
information. KIN’s diamond holes were drilled for metallurgical andgeotechnical test work,and

36

Criteria Commentary
assay results received to date for these holes also show good correlation with nearby historical
results.
Where sampling protocols are appropriate, diamond, RC and Aircore samples, are of equal
importance in the resource estimation process.
There has been no adjustments or calibrations made to the assay data recorded in the supplied
database.
Location of
data points
HISTORIC DATA (1981‐2014)
A local survey grid was originally established in 1981 at Mertons Reward, and subsequently
extended by Hunter during 1985‐1988. During the 1990s, SOG identified a small angular error in
the base line, which resulted in substantial errors, particularly in the northern portion of the
project. Surface survey data were transformed firstly to AMG and subsequently to MGA (GDA94
zone51). This resulted in different grid transformations being applied in the northern and
southern parts of the Mertondale area.
Navigator recognised errors in the collar co‐ordinates resulting from these transformations and
as a result, a significant number of holes were resurveyed and a new MGA grid transformation
generated. This exercise largely appeared to eliminate the offset. Historical collars have been
validated against the original local grid co‐ordinates and independently transformed to MGA co‐
ordinates and checked against the database. Navigator’s MGA co‐ordinates were checked against
the surveyor’s reports. Where variations in the MGA co‐ordinate system were detected,
Navigator’s geologists deemed the errors were not large enough to have a material impact on the
resource estimation work in 2009.
All survey work carried out by Navigator was conducted in GDA94 Zone 51 using differential GPS
equipment and a network of survey controls.
Almost all the diamond and at least 80% of Navigator‘s RC holes were downhole surveyed. Pre‐
Navigator, single shot survey cameras were used, with typical survey intervals of 30‐40 metres.
There were some variation between magnetic and grid azimuths noted (up to 2°) for pre‐
Navigator drillholes, however the variations are small enough to be within acceptable limits.
Aircore holes and the majority of pre‐Navigator RC holes were not surveyed down hole, as was
the general practice of the day.
Navigator carried out down hole survey using a single shot or multi‐shot survey camera.
KIN MINING (2014‐2017)
KIN’s drill hole collars were located and recorded in the field by a contract surveyor using RTK‐
DGPS (with a horizontal and vertical accuracy of ±50mm). Location data was collected in the
GDA94 Zone51 grid coordinate system. During this program the surveyor also located one historic
Navigator diamond and 13 RC drillhole collars using the database collar positions. The collar
positions were verified using RTK‐DGPS within 1 metre.
Downhole surveying during KIN’s drilling programs was predominantly carried out by the drilling
contractor. KIN recognised that some of the downhole survey data appeared to be spurious, and
commissioned an independent downhole surveying program by a survey contractor (BHGS,
Perth) to check several drillholes at Mertons Reward, Mertondale 3‐4 and Tonto. The check
survey found occasional erroneous results with the initial surveys. This can be explained by the
fact that when the drilling company’s survey tool is run inside the drill rods, the tool’s sensors
need to be located exactly in the middle of the bottom s/s RC rod to obtain accurate readings.
Check readings by KIN personnel at different locations within the s/s rod found that variation in
azimuth can be measured up to 2°, within 1 metre from the centre of the rod, and up to 10°
further away from the centre. The positioning of the tool by the drilling contractor is assumed to
be within 1 metre of the centre of the s/s rod for the majority of the drilling program. Therefore,
given the nature of the mineralisation and the shift in apparent position of up to 5 metres (for 2°
variation) along ‘strike’ for open pit depths (<140 metres), the occasional errors are not
considered material for this resource estimation work.
In addition,if the downhole surveytool is located within 15 metres of the surface,there is risk of

37

Criteria Commentary
influence of the drill rig affecting the azimuth readings. This was observed for the survey readings,
which include total magnetic intensity (TMI) measurements, where TMI is spurious for readings
taken at downhole depths less than 20 metres. These spurious readings are included in the
database, but are not used.
One RC hole at Mertons Reward (MT17RC037) was found to have an elevation error of
approximately 8 metres at the end of hole (204 metres depth), which appears to be related to an
incorrect inclination setup of the rig’s drilling angle at commencement of drilling.
KIN supplied one digital terrain models (DTM) of the topography constructed from drill hole collar
data, and the second from a recent aerial orthophotogrammetry survey. The two DTM surfaces
correlate sufficiently close and within acceptable limits for horizontal and vertical control, and
appropriate for resource estimations.
COMMENT
The accuracy of the drill hole collar and downhole data are located with sufficient accuracy for
use in resource estimation work.
Some historical Navigator drillhole collar positions at Mertons Reward, Mertondale 3‐4 and Tonto
have recently been independently located and verified in the field, and checked against the
database.
Considering the history of grid transformations and various problems recorded in the surviving
documentation there might be some residual risk of error in the MGA co‐ordinates for old
drillholes, particularly in the northern area, however this is not considered to be material for the
resource estimations, subject of this report.
Much of the historical drilling data was recorded relative to magnetic north. Variation in magnetic
declination for the Mertondale Project area is calculated at +0.823° East (1985) to +1.301° East
(2017), with a maximum variation of +1.575° in 2005. The difference between true north and
magnetic north, and the annual variation in magnetic declination since 1985 is not significant,
therefore magnetic north measurements have been used, where true north data is unavailable,
for all survey data used in resource estimation processes.
Data
spacing and
distribution
Drill hole spacing patterns vary considerably throughout the Project area, and is deposit specific,
depending on the nature and style of mineralisation being tested.
The following table summarises the general range of drilling grid spacings and drill hole spacings

Mineralised areas have typically been drilled at hole spacings of 10‐25 metres and 12.5‐25 metre
drill grid spacings. The majority of the holes were drilled at an average dip of ‐60°, and orthogonal
to the strike of mineralisation.
Drill hole and sample interval spacing is sufficient to establish an acceptable degree of geological
and grade continuity appropriate for mineral resource estimations and classifications applied.
There has been no sample compositing, other than a few historical compositing of field samples
for some Aircore and RC samples to 1.5m, 2m and few 4m intervals. The vast majority of primary
assay intervals are 1 metre intervals for RC and Aircore samples, and predominantly 1 metre
intervals for core samples.

sub‐vertically to steeply dipping to the east or west. The majority of drilling and sampling
programs were carried out to intersect mineralisation orthogonal to strike and as close to
orthogonal to dip as practical.
Geological interpretation of Mertons Reward is largely based on drill data together with
information retrieved from historic mapping and mine plans of the old workings, and thus there
is a high level of confidence in the interpretation.
At Mertondale 3‐4 gold mineralisation is associated with the intrusive porphyry contact, where
the contact can be used as a mineralisation guide or ‘marker’ horizon.
The majority of holes were inclined at ‐60° and drilled orthogonal to the interpreted strike of the
target mineralisation (i.e. towards 245° to 270°). In some areas, historical vertical drillholes were
completed, as initial reconnaissance drilling, or specifically targeting interpreted flat‐ to shallow‐
dipping mineralisation.
The chance of sample bias introduced by sample orientation is considered minimal. No
orientation sampling bias has been identified in the data thus far.
Sample
security
HISTORIC DRILLING (1981‐2014)
No sample security details are available for pre‐Navigator (pre‐2004) drill samples.
Navigator’s drill samples were collected from the riffle splitter in pre‐numbered calico bags at the
drill rig site. Samples were collected by company personnel from the field and transported to
Navigator’s secure yard in Leonora, where the samples were then batch processed (drillhole and
sample numbers logged into the database) and then packed into ‘bulkabag sacks’. The bulkabags
were tied off and stored securely in Navigator’s yard, until transporting to the laboratory. There
was no perceived opportunity for the samples to be compromised from collection of samples at
the drill site, to delivery to the laboratory.
KIN MINING (2014‐2017)
KIN’s RC drill samples were collected from the riffle splitter in pre‐numbered calico bags at the
drill rig site. The samples were then batch processed (drillhole and sample numbers encoded onto
a hardcopy sample register) in the field, and then transported and stacked into ‘bulkabag sacks’
at KIN’s secure yard in Leonora. The bulkabags were tied off and stored securely in the yard. The
laboratory’s (SGS) transport contractor was utilized to transport the bulkabags to the laboratory.
There was no perceived opportunity for the samples to be compromised from collection of
samples at the drill site, to delivery to the laboratory, where they were stored in their secure
compound, and made ready for processing.
On receipt of the samples, the laboratory (SGS) independently checked the sample submission
form to verify samples received, and readied the samples for sample preparation. SGS’s sample
security protocols are of industry acceptable standards.
Audits or
reviews
Historic drilling and sampling methods and QA/QC are regarded as not being as thoroughly
documented compared to today’s current standards. A review of various available historical
company reports of drilling and sampling techniques indicates that these were most likely
conducted to the best practice industry standards of the day.
A review of the Mertondale Project’s database, drilling and sampling protocols, and so forth, was
conducted and reported on by independent geological consultants MS in 2009. Their report
highlighted various issues, which had subsequently been mostly rectified by Navigator prior to
2014, and most recently by KIN.
During 2017, CM have reviewed and carried out an audit on the field operations and database.
Drilling and sampling methodologies observed during the site visits are to today’s industry
standard. Similarly there were no issues identified for the supplied databases, which would be
considered material.
KIN is in the process of completing validation of all historical logging data and to standardise the
loggingcode system byincorporatingthe SOG and Navigator loggingcodes into one,and

39

Criteria Commentary
converting all historical logging into the standardized code system. This is an ongoing process and
is not yet completed.
During the review, CM logged the oxidation profiles (‘base of complete oxidation’ or “BOCO”, and
‘top of fresh rock’ or “TOFR”) for each of the deposit areas, based on visual inspection of selected
RC drill chips from KIN’s recent drilling programs, and a combination of historical and KIN’s
drillhole logging, with final adjustments made with input from KIN geologists. The oxidation
profiles were used to assign bulk densities and metallurgical recoveries to the resource models.
Bulk density testwork in the past has been inconsistent with incorrect methods employed, to
derive specific gravity or in‐situ bulk density, rather than dry bulk density. Navigator (2009) and
recent KIN (2017) bulk density testwork was carried out using the water immersion method on
oven dried, coated samples to derive dry bulk densities for different rock types and oxidation
profiles. This information has been incorporated into the database for resource estimation work.
CM conducted site visits during 2017 to the laboratory to validate the methodology.
Recent (2014‐2017) RC and diamond drilling by KIN include some twinning of historical drillholes
within the Mertondale Project area. In addition, KIN’s infill drilling density is considered
sufficiently close enough to enable comparison with surrounding historic information, and there
is no material difference of a negative nature between historical drilling information and the KIN
drilling information. KIN’s diamond holes were drilled for metallurgical and geotechnical test
work, and assay results for these holes also show good correlation with nearby historical results.
Drilling, Sampling methodologies and assay techniques used in the historical and recent drilling
programs are considered to be appropriate and to mineral exploration industry standards of the
day.

Gold was initially discovered in the Mertondale area in 1899 by Mr. Fred Merton. The Mertons
Reward (MR) underground gold mine (M37/1284) was the direct result of his discovery. The main
mining phase at MR was carried out from 1899 to 1911. Historic underground production records
to 1942 totalled 88,890t @ 21.0g/t Au (60,520oz) which represents the only recorded mining
conducted at Mertons Reward.
Between 1981‐1984 Telluride Mining NL, Nickel Ore NL, International Nickel (Aust) Ltd and
Petroleum Securities Mining Co Pty Ltd conducted exploration programs in the Mertondale area.
Hunter Resources Ltd began actively exploring the region 1984‐1989, Hunter submitted a Notice
of Intent (NOI) to mine in 1986 and established a JV with Harbour Lights to treat ore from the
Mertondale 2 (M37/1284) and Mertondale 3 pits (M37/82). Between 1986 and 1993 the adjoining
Mertondale 4 pit (M37/82 and 81) was mined. Harbour Lights acquired the project in 1989 from
Hunter. Ashton Gold eventually gained control of Harbour Lights. Large scale mining in the region
was completed in 1993 with the mining of the Mertondale 2 and Mertondale 3‐4 pits (M37/81 and
M37/82). In 1993 Ashton’s interest was transferred to Aurora Gold who established a JV with MPI
followed by Sons of Gwalia who entered into a JV with Aurora.
Historic gold production from the Mertondale Mining Centre.
Sons of Gwalia (SOG) eventually obtained control of the project in 1997 but conducted limited
exploration drilling. In 2004 Navigator Mining Pty Ltd (Navigator) acquired the entire existing
tenement holding from the SOG administrator. Navigator conducted the majority of recent
exploration drilling in the Mertondale area. KIN acquired the project from Navigator’s
administrator in late 2014. Historic production from the Mertondale Mining Centre totals 274,724
oz of gold.
KIN’s drilling is focused in areas comprising historical drilling conducted by the above mentioned
previous operators.
Geology The Mertondale Project area is located 35‐45km NNE of Leonora in the central part of the
Norseman‐Wiluna Greenstone Belt, which extends for some 600 km on a NNW trend across the
Archean Yilgarn Craton of Western Australia.
In broad terms the stratigraphy consists of a central felsic volcanic sequence bounded by tholeiitic
basalt, dolerite, and carbonaceous shale ± felsic porphyry sequences.
The four recognised deposits and all the known mineralisation is located within the north trending
Mertondale Shear Zone (MSZ).
Two distinct north trending mineralised zones are recognized within the MSZ. The western zone
includes Quicksilver, Tonto, Eclipse and Mertondale 5, while the eastern zone includes the
Merton's Reward, Mertondale 2 and Mertondale 3‐4 deposits.
Within the Mertondale Project area, most of the known mineralisation is hosted in sheared mafics,
with local porphyry bodies and sediment units. Some of the sediment units are graphitic, notably
in the western mineralised zone.
Eastern Mineralised Zone
In the Mertons Reward ‐ Mertondale 2 area, two distinct types of high grade lodes were historically
recognized:

Shear Lodes: Steeply dipping structures containing abundant quartz‐carbonate veinlets
accompanied by finely disseminated pyrite‐arsenopyrite, and

Intershear Lodes: Narrow, flat to moderately dipping auriferous quartz veins up to about
40cm thick, enveloped in carbonate‐altered zones up to +10m thick, which contain pyrite
and arsenopyrite and lower grades of Au. These are usually truncated to the east and
west by the steep dipping shear lodes.
Geological interpretation of Mertons Reward is largelybased on historic mappingand mineplans

Criteria Commentary
of the historic workings, and thus there is a high level of confidence in the interpretation.
At Mertondale 3‐4 gold mineralisation is associated with the intrusive porphyry contact, where the
contact can be used as a mineralisation guide or ‘marker’ horizon.
Western Mineralised Zone
The western mineralised zone typically comprises dark mafic mylonites, sedimentary units
including carbonaceous shales, mafic intrusives and mafic‐intermediate and felsic volcanics. Felsic
porphyry intrusives occur irregularly within the shear zone. The black sulphide‐rich mafic mylonite
typically contains anomalous gold values up to 0.5 g/t Au in the resource areas.
Lithologies at Tonto are black mafic mylonite, a black shale, shale, quartz‐dolerite, basalt, basaltic
andersite and felsic volcanics. The steeply dipping high grade lode at Tonto is more than likely
structurally controlled and appears to potentially have a shallow southerly plunge. Visually the
grade still remains very difficult to pick with no obvious association with sulphide content, quartz
veining or alteration of either graphite or sericite.
The footwall consists of the massive quartz dolerite. This dolerite has a noticeable bleached or
carbonated halo along its immediate contact with the mylonite but grades into a strongly chloritic
massive barren quartz dolerite.
The Western mineralised zone at Mertondale 5 typically comprises dark mafic mylonites,
sedimentary units including carbonaceous shales, mafic intrusives and mafic‐intermediate and
felsic volcanics. Felsic porphyry intrusives occur irregularly within the shear zone. The black
sulphide‐rich mafic mylonite typically contains anomalous gold values in the resource areas.
Drill hole
Information
Material drilling information used for the resource estimation has previously been publicly
reported in numerous announcements to the ASX by previous operators of the Mertondale
Project, including Navigator (2004‐2014) and KIN since 2014.
Data
Aggregation
methods
When exploration results have been reported for the resource areas, the intercepts are generally
reported as weighted average grades over intercept lengths defined by geology or lower cut‐off
grades, without any high grade cuts applied. Where aggregate intercepts incorporated short
lengths of high grade results, these results were included in the reports.
Since 2014, KIN have reported RC drilling intersections with low cut off grades of greater than or
equal to 0.5 g/t Au and a maximum of 2m of internal dilution at a grade of <0.5g/t Au.
There is no reporting of metal equivalent values.
Relationship
Between
Mineralisation
widths and
intercept
lengths
The orientation, true width and geometry of the mineralised zones have been determined by
interpretation of historical drilling and verified by KIN’s drilling. The majority of drill holes are
inclined at ‐60° towards 270° (west), which is regarded as the optimum orientation to intersect the
target mineralisation. Since the mineralisation is steeply dipping, drill intercepts are reported as
downhole widths, and not true widths. Accompanying dialogue to reported intersections normally
describes the attitude of the mineralisation.
Diagrams A plan and type sections for each resource area are included in the main body of the report.
Balanced

Public reporting of exploration results by KIN and past explorers for the resource areas are
considered balanced and included representative widths of low and high grade assay results.

intention of increasing the Mertondale resources and converting the Inferred portions of the

Database
Integrity
All sample data, subject of this report and used for resource estimation work, is obtained from
various drilling programs carried out since 1981. Data was obtained predominantly from Reverse
Circulation (RC) drilling, and to a lesser extent, diamond core (Diamond) drilling and Air Core
(Aircore) drilling.
Companies involved in the collection of the majority of the exploration data prior to 2014 include:
Nickelore NL (“Nickelore”) 1981‐1982; Hunter Resources Ltd (“Hunter”) 1984‐1988; Harbour Lights
Mining Ltd (a joint owned company of Ashton Gold WA Ltd and Carr Boyd Minerals Pty Ltd ‐ “HLML”)
1988‐1993; Mining Project Investors Pty Ltd (“MPI”) 1993‐1996; Sons of Gwalia Ltd (“SOG”) 1996‐
2004; Navigator Resources Ltd (“Navigator”) 2004‐2014.
KIN exploration data from 2014 to 2017 has been acquired predominantly from RC and some
diamond drilling, representing approximately 6% of the supplied Mertondale Project database.
The database could not be fully verified regarding the reliability and accuracy of a substantial
portion of the historical data, however the recent drilling by KIN has enabled comparison with the
historical data and there is no material differences observed of a negative nature.
Database checks conducted by KIN and others are within acceptable limits. There is missing data,
however it is regarded as minimal. It is not possible to identify errors that might have occurred prior
or during digital tabulation of historic (pre‐2004) data, however the amount of historic data used in
the resource estimation is minimal and the effect would not be material.
The logging data coded in the database uses at least four different lithological code systems, a
legacy of numerous past operators (Hunter, MPI, SOG and Navigator). Correlation between codes
is difficult to establish, however can be achieved with effort. Based on historical reports, drill hole
logging procedures appear consistent with normal industry practices of the time.
KIN has attempted to validate historical logging data and to standardise the logging code system by
incorporating the SOG and Navigator logging codes into one. This is an ongoing process and is not
yet completed.
Drilling conducted by Navigator and KIN has been used to scrutinize and calibrate historic logging
data. This has enabled KIN to establish good geological control, which has been used to derive the
geological interpretations in current resource work.
Navigator uploaded the original assay files received from the labs via a database administrator using
Datashed to minimise loading errors. An export of the data was then used to create a Microsoft
Access (“Access”) database for use in Surpac.
In 2009, MS (“MS”) completed a mineral resource estimate report for the Mertondale Project area,
including the Mertons Reward, Mertondale 2, Mertondale 3‐4 and Mertondale 5 deposits. MS
carried out extensive database verification, which included checks of surface survey positions,
downhole surveys and assay data against original records. MS reported on verification of 92% of
the assay records in 50 randomly selected check holes with < 0.2% discrepancies. Identified issues
were then addressed by Navigator.
Since 2014, KIN geologists have conducted verification of historic drilling, assays, geological logs and
survey information against the digital database, and in the field, including reviewing historic reports
and visual confirmations of Datashed, Surpac and Access databases. KIN have not reported any
significant issues with the database.
KIN has validated the database in Datashed and in Surpac prior to Resource estimation. These
processes checked for holes that have missing data, missing intervals, overlapping intervals, data
beyond end‐of‐hole,holes missingcollar co‐ordinates,and holes with duplicate collar co‐ordinates.

CM carried out continuous database review during the 2017 resource estimation process.
During 2017, CM also carried out an independent data verification. 8,991 assay records for KIN’s
2014‐2017 drilling programs were verified by comparing laboratory assay reports against the
database. 3 errors were found, which are not considered material and which represents less than
0.01% of all database records verified for KIN’s 2014‐2017 drilling programs.
Site Visit KIN’s geological team have conducted multiple site visits including supervision and management of
drill programs within each of the Resource areas.
Dr Spero Carras (Competent Person) of CM, was involved in the Leonora district at the Harbour
Lights and Mertondale areas during the 1980s, and is familiar with the geology and styles of gold
mineralisation within the Mertondale Project area. He revisited the Leonora area during 2017 to
review the projects, drilling, sampling and general geology.
Messrs Mark Nelson and Gary Powell (Competent Persons) also conducted site visits to the resource
areas, and they have independently reviewed drill core, existing open pits, surface exposures,
drilling, logging and sampling procedures. Mr Nelson also collected representative rock samples of
mineralisation from the Mertondale 3 pit for bulk density determination.
Geological
Interpretation
The Mertondale Project area is located 20‐40km NE of Leonora in the central part of the Norseman‐
Wiluna Greenstone Belt, which extends for some 600 kilometres on a NNW trend across the
Archean Yilgarn Craton of Western Australia.
In broad terms the stratigraphy consists of a central felsic volcanic sequence bounded by tholeiitic
basalt, dolerite, and carbonaceous shale ± felsic porphyry sequences.
The four recognised deposits and all the known mineralisation is located within the north trending
Mertondale Shear Zone (MSZ).
Two distinct north trending mineralised zones are recognized within the MSZ. The western zone
includes Quicksilver, Tonto, Eclipse and Mertondale 5, while the eastern zone includes the Merton's
Reward, Mertondale 2 and Mertondale 3‐4 deposits.
Within the Mertondale Project area, most of the known mineralisation is hosted in sheared mafics,
with local porphyry bodies and sediment units. Some of the sediment units are graphitic, notably
in the western mineralised zone.
Eastern Mineralised Zone
In the Mertons Reward ‐ Mertondale 2 area, two distinct types of high grade lodes were historically
recognized:

Shear Lodes: Steeply dipping structures containing abundant quartz‐carbonate veinlets
accompanied by finely disseminated pyrite‐arsenopyrite, and

Intershear Lodes: Narrow, flat to moderately dipping auriferous quartz veins up to about
40cm thick, enveloped in carbonate‐altered zones up to +10m thick, which contain pyrite
and arsenopyrite and lower grades of Au. These are usually truncated to the east and west
by the steep dipping shear lodes.
Geological interpretation of Mertons Reward is largely based on historic mapping and mine plans
of the historic (pre‐1980) workings, and thus there is a high level of confidence in the interpretation.
At Mertondale 3‐4 gold mineralisation is associated with the intrusive porphyry contact, where the
contact can be used as a mineralisation guide or ‘marker’ horizon.
Western Mineralised Zone

carbonaceous shales, mafic intrusives and mafic‐intermediate and felsic volcanics. Felsic porphyry
intrusives occur irregularly within the shear zone. The black sulphide‐rich mafic mylonite typically
contains anomalous gold values up to 0.5 g/t Au in the resource areas.
Geological interpretation used a combination of drilling data, such as lithology, mineral percentages
(e.g. quartz veining and sulphides), weathering codes, rock colour, texture and structure to identify
mineralisation envelopes for resource estimation of each deposit.
Prescribed geological codes are assumed to have been used consistently in logging by various
geologists, though it is probable that some variations between drillholes may be a result of different
logging styles or interpretations.
The 3D wire frame interpretations of the mineralisation envelopes were produced by CM and
validated by KIN. Slight modifications to previous interpretations by independent consultants were
made before regenerating the wireframes. The ‘base of complete oxidation’ and the ‘top of fresh
rock’ DTM surfaces were produced by CM based on geological logs, and adjusted where necessary
in consultation with KIN geological staff.
Alternative interpretations of the mineralisation may have an effect on the estimation, however it
is unlikely that there would be a gross change in the interpretation, based on current information.
The resource estimation is controlled by all available data in an attempt to quantify the
mineralisation with the highest level of confidence.

a. Topography based on drill collar data
b. Bottom of Oxidation (BOCO)
c.
Top of Fresh Rock (TOFR)
d. Wireframes of pre‐existing pits and some waste dumps
e. Historic workings
3. CM carried out an Independent Review of the weathering surfaces and where necessary, based
on new drilling (both RC and diamond), geological relogging and bulk density information, the
surfaces were modified to reflect the additional information.
4. Based on geology, statistical analysis and intersection selection, domainal shapes were
wireframed at a 0.3g/t nominal edge cut‐off grade. These domainal shapes could contain
values less than 0.3g/t within the wireframes although this was minimized to prevent
smoothing dilution being incorporated into the final models. The parameters used for
intersection selection were 3m downhole, which equates to an approximate 2.5m bench
height. The intersections could include 1m of internal dilution.
5. The wireframed shapes were audited by KIN geological staff who had previous experience in
the Mertondale area whilst working for Navigator Resources Ltd.
6. Historically mined volumes were removed from the model. These shapes were based on
historical workings obtained from Mines Department information. The historical underground
shapes were expanded to be larger than that shown on Mines Department records to allow for
any overmining, which may have taken place and had not been recorded and included.
7. Each wireframe had an assigned strike, dip and plunge.
8. Compositing from the top of each shape was carried out at 1m within each wireframe. The
majority of composites (98%) were greater than 1m.
9. The domainal shapes were passed into ISATIS Software with specified strike, dip and plunge.

11. A breakdown of pre‐Resource volume for each shape was measured. This was to ensure that
modelling did not over dilute shapes due to block sizes being used.
12. The declustering program DECLUS (ISATIS) was used to produce the weights to be assigned to
each composite for statistical analysis.
13. For each shape a detailed set of weighted statistics was produced. Based on the statistics, high
grade cuts were determined for every shape and the percentage metal cut was estimated for
each deposit as shown in the below table:

14. Where a data point belonged to 2 shapes the cut allocated was determined for each domain
and independently allocated.
15. Variograms were run for each domain using ISATIS. The variograms were of very poor quality
with the dowhole variograms being the basis of fitted models. Directional variograms were
produced for downhole, down dip, down plunge. Where the downhole variograms were
calculated on an individual hole basis, variograms were not normalized. Variograms were
normalized for down dip and plunge. Raw variograms were used in subsequent work.
16. The Author, Dr. S. Carras had extensive experience in the Leonora Belt during the 1980's and
has had familiarity with the nature of the mineralisation. The shears are made up of plunging
Boudins. The nature of Boudins is such that there is a central high grade core. This means that
once inside a Boudin the grades are relatively homogenous and the nugget effect is small.
Horsetail splays which occur on the periphery of Boudins give rise to the "string problem" in
Ordinary Kriging (OK) where samples on edges are given abnormally high values. To overcome
the "string problem" three estimations were produced, OK, Inverse Distance Squared (ID2) and
Inverse Distance Cubed (ID3). Distance weighting methods do not suffer from the "string
problem".
17. The following parameters were used in modelling OK, ID2 and ID3:

A minimum number of samples were as follows:

Mertons Reward: 4

Mertondale 3‐4: 4

Tonto: 12

Mertondale 5: 2

A maximum number of samples of 32

The discretisation parameters were 2 x 2 x 2

A maximum of 2 samples per hole

Note: for blocks that did not meet these requirements, the parameters were relaxed
and the search radii were increased.

To minimize the striping effect created by estimation in narrow shapes, the
downhole search radii were increased.
18. The ranges of search and directions used were applied on a shape by shape basis. The aim
was to produce OK results for the majority of shapes where there had been adequate data to
produce meaningful variography. Small shapes where there was inadequate data were
estimated using distance weighting squared methodology rather than OK.
19. The fundamental block size used was:

Small blocks were used to ensure adequate volume estimation where shapes were

20. Scatter plots were then produced which compared OK, anisotropic ID2 and ID3 for the small
blocks.
21. The models were then visually checked on a ‘section by section’ basis of block versus drillholes
and ID2 proved to be the best fit, which clearly defined the Boudins and eliminated the "string
problem".
22. The small blocks produced by ID2 were then composited to form medium (quarter) sized blocks
and panels. The block dimensions for the medium (quarter) sized blocks and panels were:

Quarter size blocks were used for reporting Resources.
23. Plots were produced of frequency histograms in domains for point data and for blocks.
24. To check that the interpolation of the block model honoured the drill data, validation was
carried out comparing the interpolated blocks to the sample composite data. The validation
plots showed good correlation thus the raw drill data was honoured by the block model.
25. Volumes within wireframes were determined and these were then compared with the block
estimates of the volumes within those wireframes on a shape by shape basis to ensure that
volumes estimated were correct.
26. Classification was carried out using a combination of drillhole density, drillhole quality, and
geology as the guide.
27. Resources were estimated within an AUS$2,200 optimised pit shell provided by Entech (Perth).
The optimised pit shells provided a reasonable basis for defining the portion of models that
may have prospects for economic exploitation in the foreseeable future and could therefore
reasonably be declared as Open Pit Resources. (Optimisation used a dilution of 5% and a
recovery of 95%. This was minimal and was only used to define the Resource not the Reserve.
The Resources reported are undiluted and do not have an ore loss applied.)
28. Operating cost estimates developed by KIN indicated that a break even mill feed cut‐off grade
for deposits in the Mertondale area was likely to be 0.5g/t Au.

Cut‐off
Parameters
Operating cost estimates provided by KIN's engineering consultants indicate a break even mining

Mining
Factors or
Assumptions
Previous mining is mostly in the oxide/transition zone. In fresh rock, historical underground mining
has occurred at Mertons Reward. Open pit mining will be the mining method employed going
forward.
Historical gold production is over 270,000 ounces of gold;

Mertondale 3‐4 Open Pit: 1.3Mt @ 4.3g/t Au;

Mertondale 5 Pit: 385,000t @ 2.56g/t Au;

Mertondale 2 Pit: 35,000t @ 2.7g/t Au;

Merton’s Reward: 90,000t@21g/t Au from undergroundproduction 1899‐1942.
Metallurgical
Factors or
Assumptions
In 2016 – 2017 KIN’s drilling program included a series of RC and DD drillholes to collect samples
for geotechnical and metallurgical testwork.
In the Mertondale Project area, recoveries for oxide material were generally high (approximately
mid‐nineties), however in the Mertons Reward area, slightly lower recoveries were returned for
transition and fresh material (mid‐eighties). This was associated with the presence of a minor
amount of sulphides (e.g. pyrite, arsenopyrite).
For Mertondale 3‐4, recoveries were generally high for oxide and transition (mid‐nineties), and
90% for fresh.
Tonto, recoveries were high for oxide (mid‐nineties) and transition (+90%), and high sixties for
fresh. The lower recoveries experienced for fresh material in Tonto is due to the presence of
preg‐robbing graphitic shales. Testwork has shown that the use of modified activated carbon has
increased the recovery.
It is known that within Mertondale 5 graphitic shales occur, and while these are present within
the MSZ, recent testwork by KIN has shown that they can be passivated to an extent through the
use of modified activated carbon.
During the mining process, and where necessary, selective extraction of the graphitic shales is
envisaged to be possible so that successful segregation and quarantining of the shale material can
be achieved,so as to mitigatepotential contamination of ore in theprocessplant.
Environmental
Factors
or
Assumptions
Three open pits and their associated waste rock landforms (i.e. Mertons Reward, Mertondale 3‐4
and Mertondale 5), the historical Mertons Reward underground workings and battery tailings are
encompassed by the current mineral resource estimate work. The Tonto resource area has not been
subjected to any previous mining activity.
Historical mining at each of the Mertondale deposits sites, including waste rock landforms have not
demonstrated any impacts that cannot be managed in normal operations. Studies completed to
date, on ore and waste characterisations for previous and potential mining and processing
operations, have not identified any potential environmental impacts that cannot be managed by
normal operations. In addition, Navigator’s environmental bonds lodged with the DMP for previous
operations have since been returned to Navigator, following the rehabilitation of those operations.
Bulk Density Prior to 2014, there have been numerous programs of bulk density testwork conducted by several
companies at different times on diamond drill core and/or RC drill chips for some of the various
deposits. Generally the testwork has not been conclusive, since the testwork methodology has not
been adequately described in the historical reports, or when it has, the testwork itself was not
carried out usingan acceptable method to determine drybulk density. Often,when described,the

50

Commentary

Criteria

testwork measured specific gravity, not bulk density, and in cases where bulk density was reported, the moisture content was not taken into account.

In 2009 Navigator Resources Ltd submitted 189 half or whole diamond core samples to Amdel Mineral Laboratories Ltd’s (“Amdel”) Kalgoorlie laboratory for bulk density determination by the water immersion method. The core samples were a mixture of half core and whole core samples ranging from 10cm to 30cm in length, and were taken at downhole intervals of roughly every 2 to 3 metres. The samples were firstly weighed, oven dried overnight at 110°C, and weighed again to determine moisture content. Those samples that were likely to absorb water were then sealed, using hairspray, prior to immersion in water. It is not known what proportion of samples were not sealed, however it is likely that only fresh, non‐porous samples were not sealed.

In 2017, KIN carried out a diamond drilling program to include obtaining samples for bulk density testwork. Four diamond drill holes were drilled into the major parts of mineralised zones at Mertons Reward and Tonto.

A total of 484 half or quarter core samples, of varying lengths (5‐20cm) were submitted to an independent laboratory in Perth for bulk density determinations by the water immersion method. The core samples were a mixture of half core and quarter core samples ranging from 5cm to 20cm in length, and were taken at downhole intervals of roughly every 1 metre. The samples were firstly weighed, oven dried overnight at 110°C, and weighed again to determine moisture content. The samples were then sealed, using hairspray, prior to immersion in water.

In addition, Mr M Nelson (Consultant to CM) also took representative samples of mineralised material from the Mertondale 3‐4 pit and submitted to the laboratory for bulk density determination.

During the 2017 bulk density testwork and estimation process, Dr S Carras and Mr G Powell (Consultant to CM) visited the laboratory and identified some improvements for consideration in the bulk density determination process, particularly for small core pieces to give better precision of measurements. The suggested improvements were implemented and precision improved.

When estimating the bulk density for pieces of diamond drill core, it was found that the larger sized samples gave more repeatable results and these were mostly used in assigning the bulk densities. Based on measurements the following bulk density parameters were used for the Mertondale area:

Deposit Name Oxide Transition Fresh
Mertons Reward 1.8 2.2 2.8
Mertondale 3‐4 2.0 2.2 2.7
Mertondale 5 2.0 2.2 2.5
Tonto 1.9 2.3 2.7

For Mertondale 5 the bulk densities are based on historic open pit performance.

Classification Classification was based on a combination of drillhole spacing, drillhole quality and confidence in geological continuity. In general all deposits were drilled on the following nominal grids (N x E):

  • Mertons Reward: 25m x 12.5m

  • Mertondale 3‐4: 25m x 12.5m  Tonto: 25m x 20m  Mertondale 5: 25m x 12.5m

In general drillhole spacing of 25m x 20m resulted in mineralisation being classified as Indicated.

Drillhole spacing generally increases with depth and as a result deeper mineralisation is mostly allocated to the Inferred category.

Criteria Commentary
The Mineral Resource estimate appropriately reflects the view of the Competent Person.
Audits and
Reviews
Navigator Resources had worked with McDonald Speijers (January 2009) to produce estimates for
the Mertondale deposits using the recovered fraction technique. KIN personnel carried out audits
and internal reviews of the data, assay, survey, wireframes and geological interpretations used by
CM in carrying out the Resource estimation for Mertons Reward, Mertondale 3‐4, Tonto and
Mertondale 5. CM also carried out detailed reviews of all data.
Bulk density determination methodology was audited by S Carras and G Powell (Consultant to CM)
through visitation of the independent laboratory.
Snowden (July/August 2017) carried out an independent audit of Mertons Reward and Mertondale
3‐4. There were no material issues.
Discussion
of Relative
Accuracy and
Confidence
KIN embarked on a program of infill drilling, including twinning of historical drillholes. The drilling
largely substantiated the position and tenor of mineralisation. It also validated the information
obtained from various drilling campaigns.
In the modelling process every attempt has been made to eliminate the "string effect" problem
associated with the estimation of narrow vein structures through the use of ordinary kriging. This
has been achieved through the use of distance weighting estimates correlated back to ordinary
kriging estimates. This method, although heuristic has been validated by extensive review of the
block models and the drillhole data.
Every attempt has been made in the modelling to reduce the smoothing effect which results when
using a low cut‐off grade to determine boundary positions and limit the amount of dilution in the
Resource so that it can be correctly diluted for Reserve.
In all high coefficient of variation orebodies, local estimation is very difficult to achieve due to the
high nugget effect of the gold. This means that small parcels of ore are difficult to estimate without
further information such as closer spaced grade control drilling.

(Criteria in this section apply to all succeeding sections)

Criteria Commentary
Sampling
techniques
All sample data, subject of this report and used for resource estimation work, is obtained from
various drilling programs carried out since 1985. Data was obtained predominantly from Reverse
Circulation ("RC") drilling, and to a lesser extent, diamond core ("Diamond") drilling and Air Core
("Aircore") drilling.
There is limited exploration data available prior to 1985, where it is believed that exploration was
more focused on base metals, and not gold. Companies involved in the collection of the majority
of the gold exploration data since 1985 and prior to 2014 include: Thames Mining NL (“Thames”)
1985; Centenary International Mining Ltd (“CIM”) 1986‐1988, 1991‐1992; Metana Minerals NL
(“Metana”) 1986‐1989; Sons of Gwalia Ltd (“SOG”) 1989, 1992‐2004; Pacmin Mining Corporation
(“Pacmin”) 1999, and Navigator Resources Ltd (“Navigator”) 2004‐2014.
Kin Mining Ltd (“KIN”) acquired the Cardinia Project in 2014.
HISTORIC SAMPLING (1985‐2014)
Drill samples were generally obtained from 1m downhole intervals and riffle split to obtain a 3‐
4kg representative sub‐sample, which were submitted to a number of commercial laboratories
for a variety of sample preparations methods, including oven drying (90‐110°C), crushing (‐2mm
to ‐6mm), pulverizing (‐75μm to ‐105μm), and generally riffle split to obtain a 30, 40 or 50 gram
catchweight for gold analysis, predominantly by Fire Assay fusion, with AAS finish. On occasions,
initial assaying have been carried out using Aqua Regia digest and AAS/ICP finish, with anomalous
samples re‐assayed by Fire Assay fusion and AAS/ICP finish.
Diamond Drilling
Half core (or quarter core) sample intervals varied from 0.3 to 1.4m, but were predominantly
taken over 1m intervals, or at geological contacts, whichever was least. The remaining core was
retained in marked core trays and stored in a secure yard for future reference. The only known
available drill core from these programs and stored at KIN’s Leonora Exploration Yard, are those
drilled by Navigator.
RC Drilling
The vast majority of Reverse Circulation (RC) drill samples were collected over 1m downhole
intervals from beneath a cyclone and then riffle split to obtain a sub‐sample (typically 3‐4kg).
After splitting, 1m sub‐samples were typically collected in pre‐numbered calico bags, and the 1m
sample rejects were commonly stored at the drill site in marked plastic bags, for future reference.
First pass sampling often involved collecting composite samples by using a scoop (dry samples)
or spear (wet samples) to obtain 3m or 4m composited intervals, with the single metre split sub‐
samples being retained at the drill site. If the composite sample assays returned anomalous
results, the single metre sub‐samples for the anomalous composite intervals were retrieved and
submitted for gold analysis.
Navigator obtained sub‐samples from wet samples using the spear method.
Data relating to historical wet samples is not available, however the number of wet samples
involved is considered to be relatively low, and not material.
There are no sample rejects available from RC drilling prior to 2014. Most drill sites have been

54

Criteria Commentary
rehabilitated and the sample bags removed and destroyed.
Aircore Drilling
The procedures for sampling of Aircore drilling is generally the same as for RC drilling, although
in earlier (pre‐2004) programs, the majority of the 1m samples were mostly stored directly on the
ground prior to sampling with a scoop. Assay results from these samples are not used for resource
estimation work, however they do sometimes provide a guide in interpreting geology and
mineralisation continuity.
When drilling under dry conditions, Aircore samples should be of a comparable quality to RC
samples, when implementing same sampling techniques, therefore Aircore sample assay results
were only used for resource estimation work if the 1m sub‐samples were obtained by riffle
splitting of the primary sample, prior to placing on the ground.
There are no sample rejects available from AC drilling prior to 2014. Most drill sites have been
rehabilitated and the sample bags removed and destroyed.
RAB Drilling
Sample return from Rotary Air Blast (RAB) drilling is collected from the annulus between the open
hole and drill rods, using a stuffing box and cyclone. Samples are usually collected at 1 metre
intervals and placed on the ground with 3‐4kg sub‐samples collected using a scoop or spear. Up‐
hole contamination of the sample is commonplace, therefore this type of drilling and sampling is
regarded as reconnaissance in nature and the samples indicative of geology and mineralisation.
The qualities of samples are not appropriate for resource estimation work and are only
sometimes used as a guide for interpreting geology and mineralisation.
KIN MINING (2014‐2017)
Diamond Drilling
Diamond drill core (HQ3) samples collected for analysis were longitudinally cut in half, and then
in quarters, using a powered diamond core saw blade centered over a cradle holding the core in
place. Core sample intervals varied from 0.2 to 1.1m, but were predominantly taken over 1m
intervals, or at geological contacts, whichever was least. The remaining core was retained in their
respective core trays and securely stored in KIN’s yard in Leonora for future reference.
RC Drilling
During drilling, sample return is passed through a cyclone and stored in a sample collection box.
At the end of each metre, the cyclone underflow is closed off, the underside of the sample box is
opened and the sample passed down through a riffle splitter.
All RC sub‐samples were collected over one metre downhole intervals and averaged 3‐4kg.
Sample reject from the riffle splitter were retained and stored in marked plastic bags, and located
near to each drillhole collar.
All drilling, sample collection and sampling handling procedures were conducted and/or
supervised by KIN geology personnel to high level industry standards. QA/QC procedures were
implemented during each drilling program to industry standards.
Analysis
Once received at the assay laboratory, diamond core and RC samples were oven dried (105‐
110°C), crushed (‐6mm & ‐2mm), pulverised (P85% ‐75μm) and split to obtain a representative
50 gram sample catchweight for gold only analysis using Fire Assay fusion with AAS finish.
COMMENT
For some earlier (pre‐2004) drilling programs, RC and Aircore samples were obtained at 1.5, 2 or
4 metre downhole intervals.
For resource estimation work, Diamond, RC and some Aircore drilling data was used where
appropriate. RAB drillingdata was not used for resource estimation but was sometimes used as

HISTORIC DRILLING (1985‐2014)
Diamond Drilling
Diamond drilling was carried out using industry standard ‘Q’ wireline techniques, with the core
retrieved from the inner tubes and placed in core trays. Core sizes include NQ/NQ3 (Ø 45‐48mm)
and HQ/HQ3 (Ø 61‐64mm). At the end of each core run, the driller placed core blocks in the tray,
marked with hole number and depth. Core recovery was usually measured for each core run and
recorded onto the geologist’s drill logs.
RC Drilling
RC drilling used conventional reverse circulation drilling techniques, utilising a cross‐over sub,
until the late 1980s, when the majority of drilling companies started changing over to using face‐
sampling hammers with bit shrouds. Drill bit sizes typically ranged between 110‐140mm. Samples
obtained from conventional RC drilling techniques with cross‐over subs often suffered from down
hole contamination (e.g. smearing of grades), especially beneath the water table. Samples
obtained from RC drilling techniques using the face sampling hammer suffered less from down
hole contamination and were more likely to be kept dry beneath the water table, particularly if
auxiliary and booster air compressors were used. These samples are considered to be more
reliable and representative.
Aircore Drilling
Aircore drilling is a form of RC drilling, but generally utilizing smaller rigs and smaller air
compressors, compared to standard RC drill rigs of the times. Aircore bits are hollow in the centre,
with the kerf comprising cutting blades or ‘wings’ with tungsten‐carbide inserts. Drill bit
diameters usually range between 75‐110mm.
The vast majority of Aircore drilling (>60%) was conducted by Navigator utilising suitable rigs with
appropriate compressors (eg 250psi/600cfm). Aircore holes were drilled mostly into the
weathered regolith using ‘blade’ or ‘wing’ bits, until the bit was unable to penetrate further
(‘blade refusal’), often near to the fresh rock interface. Hammer bits were used only when it was
deemed necessary to penetrate harder rock types. Holes ranged in depth from 2m to 109m,
averaging 40 metres.
RAB Drilling
RAB drilling is carried out using small air compressors (eg 250psi/600cfm) and drill rods fitted with
a percussion hammer or blade bit, with the sample return collected at the drillhole collar using a
stuffing box and cyclone collection techniques. Drillhole sizes generally range between 75‐
110mm.
KIN MINING (2014‐2017)
Diamond Drilling
Diamond drilling was carried out by contractor Orbit Drilling Pty Ltd (“Orbit Drilling”) with a truck‐
mounted Hydco 1200H drill rig, using industry standard ‘Q’ wireline techniques. Drill core (HQ3)
is retrieved from the inner tubes andplaced inplastic core trays and each core run depth recorded

56

Criteria Commentary
onto core marker blocks and placed at the end of each run in the tray.
Drillhole deviation was measured at regular downhole intervals, typically at 10m from surface,
thence every 30m to bottom of hole, using electronic multi‐shot downhole survey tools (i.e.
Reflex EZ‐TRAC or Camteq Proshot).
Core orientation was obtained for each core run where possible, using electronic core orientation
tools (e.g. Reflex EZ‐ACT) and the ‘bottom of core’ marked accordingly.
RC Drilling
RC drilling was carried out by Orbit Drilling’s truck‐mounted Hydco 350RC drill rigs with
350psi/1250cfm air compressor, with auxiliary and booster air compressors (when required).
Drilling utilised mostly downhole face‐sampling hammer bits (Ø 140mm), with occasional use of
blade bits for highly oxidized and soft formations. The majority of drilling retrieved dry samples,
with the occasional use of the auxiliary and booster air compressors beneath the water table, to
maintain dry sample return as much as possible.
Drillhole deviations were surveyed downhole, during drilling operations, using an electronic
multi‐shot downhole tool (e.g. Reflex EZ‐TRAC). In some instances, drillholes were surveyed later
in open hole. In the later drilling programs, downhole surveying was carried out inside a non‐
magnetic stainless steel (s/s) rod, located above the hammer. Providing the tool was located in
the middle of the stainless steel rod, azimuth and dip readings were successfully recorded. A
separate independent program of downhole deviation surveying was carried out to validate
previous surveys, utilizing an electronic continuous logging survey tool (AusLog A698 deviation
tool).

COMMENT
Historical reports indicate that drill core sizes were predominantly HQ/HQ3 or NQ/NQ3, however
database details are incomplete. Most historical reports recorded core recoveries, although these
details are not included in the database. Review of some historical reports indicate that core
recoveries were generally good, although recoveries were typically less in highly fractured zones
and some highly weathered mineralised zones in the transition and oxide zones, however this
information is not recorded in the supplied database.
RC drilling is the dominant drill type at all sites. RC drilling information is generally described in
varying detail in historical reports to the DMP, including drilling companies used and drilling rig
types,however it’s not all recorded in the database supplied. Review of the historical reports

Criteria Commentary
indicates that reputable drilling companies were typically contracted and the equipment supplied
was of an acceptable standard for those times. During the 1990s, and 2000s, suitable large drill
rigs with on‐board compressors were probably complimented with auxiliary and booster air
compressors for drilling to greater depths and/or when groundwater was encountered. KIN’s
drilling was conducted with modern rigs equipped with auxiliary and booster compressors and
face sampling hammers with bit diameters typically 140mm.
When drilling under dry conditions, Aircore samples should be of a comparable quality to RC
samples, when implementing same sampling techniques. Aircore drilling data was only used in
resource estimation work, where the in‐field and laboratory sampling methodologies was
considered appropriate and limited to a number of selected Navigator drillholes.
Drill sample
recovery
HISTORIC DRILLING (1985‐2014)
Diamond Drilling
Core recovery has been recorded in most drill logs for most of the diamond drilling programs
since 1985, but is not recorded in the supplied database. A review of some historical reports
indicates that generally core recovery was good with lesser recoveries recorded in zones of
broken ground and/or areas of mineralisation. Overall recoveries are considered acceptable for
resource estimation.
RC Drilling
There is limited information recorded for sample recoveries for historical RC and Aircore drilling.
However there has been an improvement in sample recoveries and reliability following the
introduction of face sampling hammers and improved drilling technologies and equipment, since
the mid‐1980s.
KIN MINING (2014‐2017)
Diamond Drilling
Core recovery was recorded for each run by measuring total length of core retrieved against the
downhole interval actually drilled.
Diamond core recoveries were recorded in the database. Independent field reviews by the
Competent Persons (SC & GP) in 2017 of the diamond drilling rig in operation and core integrity
at the drill sites, demonstrated that diamond drill core recoveries were being maximised by the
driller, and that core recoveries averaged >95%, even when difficult ground conditions were being
encountered.
RC Drilling
Integrity of each one metre RC sample is preserved as best as possible. At the end of each 1 metre
downhole interval, the driller stops advancing the rods, retracts from the bottom of hole, and
waits for the sample to clear from the bottom of the hole through to the sample collector box
fitted beneath the cyclone. The sample is then released from the sample collector box and passed
through the 3‐tiered riffle splitter fitted beneath the sample box. Sample reject is collected in
plastic bags, and a 3‐4kg sub‐sample is collected in pre‐marked calico bags for analysis. Once the
samples have been collected, the cyclone, sample collector box and riffle splitter are flushed with
compressed air, and the riffle splitter cleaned by the off‐sider using a compressed air hose, and if
necessary a scraper. This process is maintained throughout the entire drilling program to
maximise drill sample recovery and to maintain a high level of representivity of the material being
drilled.
RC drill sample recoveries are not recorded in the supplied database, however a review by the
Competent Person (GP) in May 2017 of RC drill samples stored in the field, and observations of
the two RC drilling rigs in operation, suggests that RC sample recoveries were mostly consistent
and very good, with the samples themselves being reliable and representative of the material
being drilled.
COMMENT
Due to the lack of detailed information in the database regardinghistoric(pre‐2014)Aircore and

58

Criteria Commentary
RC drilling, no quantitative or semi‐quantitative impression of sample recovery or sample quality
is available. Given that much of the drilling at Cardinia was conducted by the same companies
and at the same times as that carried out for the Mertondale Project, where it is assumed to be
satisfactory given that the Mertondale deposits were mined in the past, by open pit methods,
where the open pits were mined to their original design limits, based on the historical drill data.
This suggests that the amount of metal recovered was probably not grossly different from pre‐
mining drill data based expectations.
During Navigators drill programs wet samples were spear sampled instead of riffle split. This is
regarded as poor sampling procedure and these samples are regarded as unreliable however the
total number of wet samples is considered to be very low.
No indication of sample bias is evident nor has it been established. That is, no relationship has
been observed to exist between sample recovery and grade.
The amount of Aircore drilling data used in the Cardinia resource estimation process is low and
regarded as not material.
Logging HISTORIC DRILLING (1985‐2014)
The logging data coded in the database uses at least four different lithological code systems, a
legacy of numerous past operators (Metana, CIM, SOG & Navigator). Correlation between codes
is difficult to establish, however it can be achieved with effort. Based on historical reports, drill
hole logging procedures appear consistent with normal industry practices of the time.
Navigator’s procedure for logging of diamond core included firstly marking of the bottom of the
core (for successful core orientations), core recovery, fractures per metre and RQD, lithology,
alteration, texture, mineralisation, weathering, and other features, and then marked up for
cutting and sampling.
Navigator RC and Aircore logging was entered on a metre by metre basis, recording lithology,
alteration, texture, mineralisation, weathering and other features. The information was entered
directly into hand held digital data loggers and transferred directly to the database, after
validation, to minimize data entry errors.
The entire length of all drillholes are logged in full from surface to bottom of hole.
Logging is qualitative on visual recordings of lithology, oxidation, colour, texture and grain size.
Logging of mineralogy, mineralisation and veining is quantitative.
Drill core photographs are only available for Navigator’s diamond drillholes.
KIN MINING (2014‐2017)
KIN’s logging of drill samples was carried out in the field (RC drilling) or at the Leonora Yard
(diamond core) and entered onto a portable computer, on a metre by metre basis for RC, and by
sample intervals and/or geological contacts for diamond core. Data recorded included lithology,
alteration, structure, texture, mineralisation, sulphide content, weathering and other features.
Drillhole collar coordinates, azimuth, dip, depth and sampling intervals are also recorded in the
drill logs in the field.
Several diamond drillholes were completed for geotechnical purposes and were independently
logged for structural data by geotechnical consultants. All diamond drill core has been
photographed, and currently stored at KIN’s yard in Leonora.
KIN geological personnel retrieved the core trays from the drill rig site and relocated them to
KIN’s yard in Leonora at the end of each day. Drill core was photographed in the field or at the
Leonora yard, prior to cutting using a diamond core saw to obtain quarter core samples for
analysis.
All information collected was entered directly into laptop computers or tablets, and transferred
to the database to be validated.
COMMENT
KIN has attempted to validate historical loggingdata and to standardize the loggingcode system

59

Criteria Commentary
by incorporating the SOG and Navigator logging codes into one. This is an ongoing process and is
not yet completed.
The level of logging detail is considered appropriate for exploration and to support appropriate
mineral resource estimation, mining studies and metallurgical studies.
Qualitative logging includes classification and description of lithology, weathering, oxidation,
colour, texture and grain size. Quantitative logging includes identification and percentages of
mineralogy, sulphides, mineralisation, veining, and in addition, logging of diamond drilling
included geotechnical data, RQD and core recoveries.
For the majority of historical drilling (pre‐2004), and all of the more recent drilling, the entire
length of drillholes have been logged from surface to ‘end of hole’. Diamond core logging is
typically logged in more detail compared to RC and Aircore drilling.
Sub‐
sampling
techniques
and sample
preparation
HISTORIC DRILLING (1985‐2014)
Historical reports for drilling programs prior to 2004, are not always complete in the description
of sub‐sampling techniques, sample preparation and quality control protocols.
Diamond Drilling
Diamond drill core (NQ/NQ3 or HQ/HQ3) samples collected for analysis were longitudinally cut in
half, and occasionally in quarters for the larger (HQ/HQ3) diameter holes, using a powered
diamond core saw blade centered over a cradle holding the core in place.
Core sample intervals varied from 0.3 to 1.4m, but were predominantly taken over 1m intervals,
or at geological contacts, whichever was least. The remaining core was retained in core trays.
Where historical reports do not describe the sampling protocol for sampling of drill core, it is
assumed that drill core was sampled as described above.
RC Drilling
Prior to 1996, limited historical information indicates most RC sampling was conducted by
collecting 1m samples from beneath a cyclone and passing through a riffle splitter to obtain a 3‐
4kg sub‐sample for analysis. RC sampling procedures are believed to be consistent with the
normal industry practices at the time. The vast majority of samples were dry and riffle split,
however spear or tube sampling techniques were used for wet samples.
Samples obtained from conventional RC drilling techniques with cross‐over subs often suffered
from down hole contamination, especially beneath the water table. Samples obtained from RC
drilling techniques using the face sampling hammer suffered less from down hole contamination
and were more likely to be kept dry beneath the water table, particularly if auxiliary and booster
air compressors were used. These samples are considered to be representative.
The vast majority of Reverse Circulation (RC) drill samples were collected at 1m downhole
intervals from beneath a cyclone and then riffle split to obtain a sub‐sample (typically 3‐4kg).
After splitting, 1m sub‐samples were typically collected in pre‐numbered calico bags, and the 1m
sample rejects were commonly stored at the drill site in marked plastic bags, for future reference.
First pass sampling often involved collecting composite samples by using a scoop (dry samples)
or spear/tube (wet samples) to obtain 3m or 4m composited intervals, with the single metre split
sub‐samples being retained at the drill site. If the composite sample assays returned anomalous
results, the single metre sub‐samples for the anomalous composite intervals were retrieved and
submitted for analysis.
Navigator obtained sub‐samples from wet samples using the spear or tube method.
Data relating to historical wet samples is not available, however the number of wet samples
involved is considered to be relatively low, and not material.
There are no sample rejects available from RC drilling prior to 2014. Most drill sites have been
rehabilitated and the sample bags removed and destroyed.
Navigator included standards, duplicate splits, and blanks within each drill sample batch, at a ratio
of 1 for every20 samples,with the number of standards beinginserted at a ratio of 1 for every

60

Criteria Commentary
50 samples.
Aircore Drilling
The procedures for sampling of Aircore drilling is generally the same as for RC drilling, although
in earlier (pre‐2004) programs, the majority of the 1m samples were mostly stored directly on the
ground prior to sampling with a scoop.
A variety of laboratories were used for analysis. Prior to 2009, duplicate samples were not
routinely collected and submitted from RC and Aircore drilling to the same laboratory
consequently overall sampling and assay precision levels can’t be quantified for that period. Since
2009, Navigator adopted a stricter sampling regime with the submission of duplicate samples at
a rate of 1 for every 50 primary samples.
While QC protocols were not always comprehensive, the results indicate that assay results from
Navigators exploration programs were reliable. Results from pre‐Navigator operators are
regarded as consistent with normal industry practices of the time.
KIN MINING (2014‐2017)
Diamond Drilling
Diamond drill core samples collected for analysis were longitudinally cut in half and quarters,
using a powered diamond core saw blade centered over a cradle holding the core in place. Core
sample intervals varied from 0.2 to 1.1m, but were predominantly taken over 1m intervals, or at
geological contacts, whichever was least. The remaining core was retained in their respective core
trays and stored in KIN’s yard for future reference.
All of KIN’s diamond drill core is securely stored at their Leonora Yard.
RC Drilling
All RC sub‐samples were collected over 1 metre downhole intervals and retained in pre‐marked
calico bags, after passing through a cyclone and riffle splitter configuration. The majority of RC
sub‐samples consistently averaged 3‐4kg. Sample reject from the riffle splitter were retained and
stored in plastic bags, and located near each drillhole site. When drilling beneath the water table,
the majority of sample returns were kept dry by the use of the auxiliary and booster air
compressors. Very few wet samples were collected through the riffle splitter, and the small
number is not considered material.
Field duplicates were taken at regular intervals at a ratio of 1:50 and assay results indicate that
there is reasonable analytical repeatability, considering the presence of nuggety gold.
COMMENT
All sub‐sampling techniques and sample preparation procedures conducted and/or supervised by
KIN geology personnel are to standard industry practice. Sub‐sampling and sample preparation
techniques used are considered to maximise representivity of the material being drilled. QA/QC
procedures implemented during each drilling program are to industry standard practice.
Samples sizes are considered appropriate for this style of gold mineralisation and is an industry
accepted method for evaluation of gold deposits in the Eastern Goldfields of Western Australia
Quality of
assay data
and
laboratory
tests
Numerous assay laboratories and various sample preparation and assay techniques have been
used since 1985. Historical reporting and descriptions of laboratory sample preparation, assaying
procedures, and quality control protocols for the samples from the various drilling programs are
variable in their descriptions and completeness.
HISTORIC DRILLING (1985‐2014)
In the initial exploration stages, Aqua Regia digest with AAS/ICP finish, was generally used as a
first pass detection method, with follow up analysis by Fire Assay fusion and AAS/ICP finish. This
was a common practice at the time. Mineralised intervals were subsequently Fire Assayed (using
30, 40 or 50 gram catchweights) with AAS/ICP finish.
Limited information is available regarding check assays for drilling programs prior to 2004.

61

Criteria Commentary
During 2004‐2014, Navigator utilised six different commercial laboratories during their drilling
programs, however Kalgoorlie Assay Laboratories conducted the majority of assaying for
diamond, RC and Aircore samples using Fire Assay fusion on 40 gram catchweights and AAS/ICP
finish.
Navigator regularly include field duplicates, Certified Reference Material (CRM) standards and
blanks with their sample batch submissions to the laboratories at average ratio of 1 in every 20
samples. Sample assay repeatability, and blank and CRM standards assay results are within
acceptable limits. Field duplicates were taken at regular intervals at a ratio of 1:50 and assay
results indicate that there is reasonable analytical repeatability, considering the presence of
nuggety gold.
KIN MINING (2014‐2017)
Sample analysis was conducted by SGS Australia Pty Ltd’s (“SGS”) Kalgoorlie and Perth
laboratories. Sample preparation included oven drying (105°C), crushing (‐6mm), pulverising
(P85% ‐75µm) and riffle split to obtain a 50 gram catchweight. Analysis for gold only was carried
out by Fire Assay fusion technique with AAS finish (SGS Lab Code FAA505).
KIN regularly insert blanks, field duplicate and CRM standards in each sample batch at a ratio of
1:20. This allows for at least one blank and one CRM standard to be included in each of the
laboratory’s fire assay batch of 50 samples. Field duplicate sample assay repeatability, blank
standards and CRM standards assay results are within acceptable limits for this style of gold
mineralisation.
SGS include blanks and CRMS as part of their internal QA/QC for sample preparation and analysis,
as well as regular assay repeats. Sample pulp assay repeatability, and internal blank and CRM
standards assay results are within acceptable limits.
COMMENT
The nature and quality of the assaying and laboratory procedures used are considered to be
satisfactory and appropriate for use in mineral resource estimations.
Fire Assay fusion or Aqua Regia digestion techniques were conducted on diamond, RC and Aircore
samples, with AAS or ICP finish.
Fire Assay fusion is considered to be a total extraction technique. The majority of assay data used
for the mineral resource estimations were obtained by the Fire Assay technique with AAS or ICP
finish. AAS and ICP methods of detection are both considered to be suitable and appropriate
methods of detection.
Aqua Regia is considered a partial extraction technique, where gold encapsulated in refractory
sulphides or some silicate minerals may not be fully dissolved, resulting in partial reporting of
gold content.
No other analysis techniques have been used to determine gold assays.
KIN’s ongoing QA/QC monitoring program identified one particular CRM that was returning
spurious results. Further analysis demonstrated that the standard was compromised and
subsequently removed and destroyed. A replacement CRM of similar grade was substituted into
the QA/QC program.
Verification
of_sampling
_and

assaying
Verification of sampling and assaying techniques and results prior to 2004 has limitations due to
the legacy of the involvement of various companies, personnel, drilling equipment, sampling
protocols and analytical techniques at different laboratories, over a twenty year period.
Since 2014, significant drill intersections have been verified by KIN’s company geologists during
the course of the drilling programs.
In 2009, Runge Ltd (“Runge”) completed a mineral resource estimate report for the Bruno Lewis
Link, Lewis and Kyte deposits. Runge carried out database verification, which included basic visual
validation in Surpac and cross check queries in Microsoft Access (“Access”). Runge did not report
any significant issues with the database.

62

Criteria Commentary
During 2017, Carras Mining Pty Ltd ("CM") carried out an independent data verification. 18,608
assay records for KIN’s 2014‐2017 drilling programs were verified by comparing laboratory assay
reports against the database. 4 errors were found, which are not considered material and which
represents only 0.01% of all database records verified for KIN’s 2014‐2017 drilling programs.
COMMENT
There is always a risk with legacy data that sampling or assaying biases may exist between results
from different drilling programs due to differing sampling protocols, different laboratories and
different analytical techniques.
Repeated examinations of historic reports on phases of diamond, RC and Aircore drilling have
been conducted from time to time. Assay results from KIN’s recent drilling are consistent with
surrounding information and as a result the information obtained from the various diamond, RC
and Aircore drilling programs (where sampling protocols are appropriate) have been accepted.
Recent (2014‐2017) RC and diamond drilling by KIN did not include twinning of historical drillholes
within the Bruno Lewis Link, Lewis and Kyte areas, however the drill density is considered
sufficiently close enough to enable comparison with surrounding historic information, and there
is no material difference between historical drilling information and the KIN drilling information.
KIN’s diamond holes were drilled for metallurgical and geotechnical test work, and assay results
for these holes also show good correlation with nearby historical results.
Where sampling protocols are appropriate, diamond, RC and Aircore samples, are of equal
importance in the resource estimation process.
There has been no adjustments or calibrations made to the assay data recorded in the supplied
database.
Location of
data points
HISTORIC DATA (1985‐2014)
Several local survey grids were established by various operators in the 1980s and 1990s. During
the 1990s, SOG transformed the surface survey data firstly to AMG and subsequently to MGA
(GDA94 zone51).
Drilling was carried out historically using various local grids. Since 2004, All Navigators drill hole
collars were surveyed on completion of drilling in the Australian MGA94, Zone51 grid using RTK‐
DGPS equipment by licensed surveyors, with more than 80% of the pickups carried out by
independent contractors.
Almost all the diamond and at least 70% of Navigator‘s RC holes were downhole surveyed. Pre‐
Navigator, single shot survey cameras were used, with survey intervals at various depths.
KIN MINING (2014‐2017)
KIN’s drill hole collars were located and recorded in the field by a contract surveyor using RTK‐
DGPS (with a horizontal and vertical accuracy of ±50mm). Location data was collected in the
GDA94 Zone51 grid coordinate system.
Downhole surveying during KIN’s drilling programs was predominantly carried out by the drilling
contractor. KIN recognised that some of the downhole survey data appeared to be spurious, and
commissioned an independent downhole surveying program by a survey contractor (BHGS,
Perth) to check the orientation of several drillholes at Cardinia. The check survey found occasional
spurious results with the initial surveys. This can be explained by the fact that when the drilling
company’s survey tool is run inside the drill rods, the tool’s sensors need to be located exactly in
the middle of the bottom stainless steel (s/s) RC rod to obtain accurate readings. Check readings
by KIN personnel at different locations within the s/s rod found that variation in azimuth can be
measured up to 2°, within 1 metre from the centre of the rod, and up to 10° further away from
the centre. The positioning of the tool by the drilling contractor is assumed to be within 1 metre
of the centre of the s/s rod for the majority of the drilling program. Therefore, given the nature
of the mineralisation and the shift in apparent position of up to 5 metres (for 2° variation) along
‘strike’ for openpit depths(<140 metres),the occasional errors are not considered material for

63

Criteria Commentary
this resource estimation work.
In addition, if the downhole survey tool is located within 15 metres of the surface, there is risk of
influence of the drill rig affecting the azimuth readings. This was observed for the survey readings,
which include total magnetic intensity (TMI) measurements, where TMI is spurious for readings
taken at downhole depths less than 20 metres. These spurious readings are included in the
database, but are not used.
KIN supplied two digital terrain models (DTM) of the topography: one DTM constructed from drill
hole collar data, and the second from a recent aerial orthophotogrammetry survey. The two DTM
surfaces correlate sufficiently close and within acceptable limits for horizontal and vertical
control, and appropriate for resource estimations.
COMMENT
The accuracy of the drill hole collar and downhole data are located with sufficient accuracy for
use in resource estimation work
Some historical Navigator drillhole collar positions at Bruno Lewis Link and Lewis have recently
been independently located and verified in the field, and checked against the database.
Considering the history of grid transformations and surviving documentation, there might be
some residual risk of error in the MGA co‐ordinates for old drillholes, however this is not
considered to be material for the resource estimations, subject of this report.
Azimuth data was historically recorded relative to magnetic north. Much of the historical drilling
data was recorded relative to magnetic north. Variation in magnetic declination for the Cardinia
Project area is calculated at +0.823° East (1985) to +1.301° East (2017), with a maximum variation
of +1.575° in 2005. The difference between true north and magnetic north, and the annual
variation in magnetic declination since 1985 is not significant, therefore magnetic north
measurements have been used, where true north data is unavailable, for all survey data used in
resource estimation processes.
Data
spacing and
distribution
Drill hole spacing patterns vary considerably throughout the Project area, and is deposit specific,
depending on the nature and style of mineralisation being tested.
Parts of the Bruno and Lewis Grade Control areas have been drilled, with vertical holes, on a close
spaced regular drill pattern of 8 mN by 5 mE. The Link area has also been drilled predominantly
with vertical holes on a wider spacing (30m x 20m).
Drill hole and sample interval spacing is sufficient to establish an acceptable degree of geological
and grade continuity appropriate for mineral resource estimations and classifications applied.
There has been no sample compositing, other than a few historical compositing of field samples
for some Aircore and RC samples to 1.5m, 2m, 3m, 4m and a few 5m intervals. The vast majority
(>90%) of primary assay intervals are 1 metre intervals for RC and Aircore samples, and
predominantly 1 metre intervals for core samples.
Orientation
of data in
relation to
geological
structure
The sheared Cardinia greenstone sequence displays a NNW to NW trend. The drilling and
sampling programs were carried out to obtain an unbiased location of drill sample data, generally
orthogonal to the strike of mineralisation.
Mineralisation is structurally controlled in sub‐vertical shear zones within the broader Cardinia
area, with a supergene component in the oxidised profile.
The vast majority of historical drilling is predominantly orientated at ‐60°/270° (west) or vertical
for Grade Control drillholes, and generally orthogonal to the strike of mineralisation. The majority
of KIN’s drilling, at Lewis, was orientated ‐60°/090° (east).
Orientation sampling bias has been identified for the vertical Grade Control drillholes, where
these are interpreted as intercepting vertically oriented mineralisation/structures. This has been
taken into account in the resource estimation process.

Sample
security
HISTORIC DRILLING (1985‐2014)
No sample security details are available for pre‐Navigator (pre‐2004) drill samples.
Navigator’s drill samples were collected from the riffle splitter in pre‐numbered calico bags at the
drill rig site. Samples were collected by company personnel from the field and transported to
Navigator’s secure yard in Leonora, where the samples were then batch processed (drillhole and
sample numbers logged into the database) and then packed into ‘bulkabag sacks’. The bulkabags
were tied off and stored securely in Navigator’s yard, until transporting to the laboratory. There
was no perceived opportunity for the samples to be compromised from collection of samples at
the drill site, to delivery to the laboratory.
KIN MINING (2014‐2017)
KIN’s RC drill samples were collected from the riffle splitter in pre‐numbered calico bags at the
drill rig site. The samples were then batch processed (drillhole and sample numbers encoded onto
a hardcopy sample register) in the field, and then transported and stacked into ‘bulkabag sacks’
at KIN’s secure yard in Leonora. The bulkabags were tied off and stored securely in the yard. The
laboratory’s (SGS) transport contractor was utilized to transport the bulkabags to the laboratory.
There was no perceived opportunity for the samples to be compromised from collection of
samples at the drill site, to delivery to the laboratory, where they were stored in their secure
compound, and made ready for processing.
On receipt of the samples, the laboratory (SGS) independently checked the sample submission
form to verify samples received, and readied the samples for sample preparation. SGS’s sample
security protocols are of industry acceptable standards.
Audits or
reviews
Historic drilling and sampling methods and QA/QC are regarded as not being as thoroughly
documented compared to today’s current standards. A review of various available historical
company reports of drilling and sampling techniques indicates that these were most likely
conducted to the best practice industry standards of the day.
A review of the Cardinia Project’s database, drilling and sampling protocols, and so forth, was
conducted and reported on by independent geological consultants Runge Ltd (2009). Their report
highlighted issues with bulk density and QA/QC analysis of the database, which have since been
identified and addressed by Navigator and most recently by KIN.
During 2017, CM have reviewed and carried out an audit on the field operations and database.
Drilling and sampling methodologies observed during the site visits are to today’s industry
standard. Similarly there were no issues identified for the supplied databases, which would be
considered material.
KIN is in the process of completing validation of all historical logging data and to standardise the
logging code system by incorporating the SOG and Navigator logging codes into one, and
converting all historical logging into the standardized code system. This is an ongoing process and
is not yet completed.
During the review, CM logged the oxidation profiles (‘base of complete oxidation’ or “BOCO”, and
‘top of fresh rock’ or “TOFR”) for each of the deposit areas, based on visual inspection of selected
RC drill chips from KIN’s recent drilling programs, and a combination of historical and KIN’s
drillhole logging, with final adjustments made with input from KIN geologists. The oxidation
profiles were used to assign bulk densities and metallurgical recoveries to the resource models.
Bulk density testwork in the past has been inconsistent with incorrect methods employed, to
derive specific gravity or in‐situ bulk density, rather than dry bulk density. Navigator (2009) and
recent KIN (2017) bulk density testwork was carried out using the water immersion method on
oven dried, coated samples to derive dry bulk densities for different rock types and oxidation
profiles. This information has been incorporated into the database for resource estimation work.
CM conducted site visits during 2017 to the laboratory to validate the methodology.
Recent (2014‐2017) RC and diamond drilling by KIN include some twinning of historical drillholes
within the Cardinia Project area. In addition, KIN’s infill drilling density is considered sufficiently
close enough to enable comparison with surroundinghistoric information,and there is no

material difference between historical drilling information and the KIN drilling information. KIN’s
diamond holes were drilled for metallurgical and geotechnical test work, and assay results for
these holes also show good correlation with nearby historical results.
Drilling, Sampling methodologies and assay techniques used in these drilling programs are
considered to be appropriate and to mineral exploration industry standards of the day.

Exploration
done by
other parties
There is limited exploration data available prior to 1985, where it is believed that exploration was
more focused on base metals, and not gold. Companies involved in the collection of the majority
of the gold exploration data since 1985 and prior to 2014 include: Thames Mining NL (“Thames”)
1985; Centenary International Mining Ltd (“CIM”) 1986‐1988, 1991‐1992; Metana Minerals NL
(“Metana”) 1986‐1989; Sons of Gwalia Ltd (“SOG”) 1989, 1992‐2004; Pacmin Mining Corporation
(“Pacmin”) 1999, and Navigator Resources Ltd (“Navigator”) 2004‐2014.
A trial pit (Bruno) was mined by Navigator in 2010, and a ‘test parcel’ of ore was extracted and
transported firstly to Sons of Gwalia’s processing plant in Leonora, and finally to Navigator’s
processing plant located at Bronzewing, where approximately 100,000 tonnes were processed at
an average head grade of 2.33 g/t au (7,493 oz Au).
In 2009, Navigator commissioned Runge Limited (“Runge”) to complete a Mineral Resource
estimate for the Cardinia deposits (Kyte, Lewis and Bruno). Runge reported a JORC 2004 compliant
Mineral Resource estimate, at a low cutoff grade of 0.7g/t Au, totaling 4.34Mt @ 1.2 g/t au
(169,700 oz Au), comprising total Indicated Resources of 1.69 Mt @ 1.2 g/t Au (64,500oz) and total
Inferred Resources of 2.65Mt @ 1.2 g/t Au (105,200oz).
KIN’s drilling is focused along the mineralised structures that host the Bruno and Lewis Trial open
pits and the Kyte deposit, and historical drilling conducted by the above mentioned previous
operators.
Geology The Project area is located 35‐40km NE of Leonora in the central part of the Norseman‐Wiluna
Greenstone Belt, which extends for some 600km on a NNW trend across the Archean Yilgarn
Craton of Western Australia.
The regional geology comprises a suite of NNE‐North trending greenstones positioned within the
Mertondale Shear Zone (MZN) a splay limb of the Kilkenny lineament. The MSZ denotes the contact
between Archaean felsic volcanoclastics and sediment sequences in the west and Archaean mafic
volcanics in the east. Proterozoic dykes and Archaean felsic porphyries have intruded the sheared
mafic/felsic volcanoclastic/sedimentary sequence.
Locally within the Cardinia Project area, the stratigraphy consists of intermediate, mafic and felsic
volcanic and intrusive lithologies and locally derived epiclastic sediments, which strike NNW with
a sub‐vertical attitude. Structural foliation of the stratigraphy dips moderately to the east.
At Bruno Lewis Link, Lewis and Kyte, primary gold mineralisation is typically characterised by finely
disseminated sulphides(pyrite),and spatiallyassociated with increased shearingand lithological

contacts between mafic and felsic lithologies. Secondary gold mineralisation occurs as supergene
enrichment within the regolith, and characterized by iron oxides, after sulphides, in the bleached,
carbonated felsic units near the footwall dolerite/felsic contact.
The central Lewis area is dominated by sub‐vertical, NW trending, highly altered, strongly
weathered mafics and intercalated beds of carbonated felsic rocks and minor sediments (including
shales).
Mineralisation at Kyte is hosted within weathered, sheared and altered mafics, and is typified in
the weathered zone, by iron‐rich alteration, after sulphides.
In some areas, gold mineralisation is highly variable in the regolith. In these areas, closer spaced
drilling was carried out to provide a high level of confidence in the interpretations.
Drill hole
Information
Material drilling information used for the resource estimation has previously been publicly
reported in numerous announcements to the ASX by Navigator (2004‐2014) and KIN since 2014.
All hole depths refer to down hole depth in metres. All hole collars are surveyed and MGA94
Zone51 DGPS positioned. Elevation (R.L.) is recorded as part of the surveyed collar pick up. Drill
holes are measured from the collar of the hole to the bottom of the hole.
Data
Aggregation
methods
When exploration results have been reported for the resource areas, the intercepts are reported
as weighted average grades over intercept lengths defined by geology or lower cut‐off grades,
without any high grade cuts applied. Where aggregate intercepts incorporated short lengths of
high grade results, these results were included in the reports.
Since 2014, KIN have reported RC drilling intersections with low cut off grades of ≥ 0.5 g/t Au and
a maximum of 2m of internal dilution at a grade of < 0.5g/t Au.
There is no reporting of metal equivalent values.
Relationship
Between
Mineralisation
widths and
intercept
lengths
The orientation, true width and geometry of the mineralised zones have been determined by
interpretation of historical drilling and verified by KIN’s drilling. The vast majority of historical
drilling is predominantly orientated at ‐60°/270° (west) or vertical for Grade Control drillholes, and
generally orthogonal to the strike of mineralisation. The majority of KIN’s drilling, at Lewis, was
orientated ‐60°/090° (east).
Since the mineralisation is steeply dipping, drill intercepts are reported as downhole widths, not
true widths. Accompanying dialogue to reported intersections normally describe the attitude of
the mineralisation.
Diagrams A plan and type sections for the resource areas are included in the main body of the report.
Balanced
Reporting
Public reporting of exploration results by KIN and past explorers for the resource areas are
considered balanced and included representative widths of low and high grade assay results.

Comments on recent bulk density and metallurgical information is included in Section 3 of this
Table 1 Report. There is no other new substantive data acquired for the resource areas being
reported on. All meaningful and material information is or has been previously reported.
Further work The potential to increase the existing resources is viewed as probable. Further work does not
guarantee that an upgrade in the resource would be achieved, however KIN intend to drill more
holes at Bruno Lewis Link, Lewis and Kyte with the intention of increasing the Cardinia Project’s
resources and converting the Inferred portions of the resources to the Indicated category.

Database
Integrity
All sample data, subject of this report and used for resource estimation work, is obtained from
various drilling programs carried out since 1981. Data was obtained predominantly from
Reverse Circulation (RC) drilling, and to a lesser extent, diamond core (Diamond) drilling and
Air Core (Aircore) drilling.
There is limited exploration data available prior to 1985, where it is believed that exploration
was more focused on base metals, and not gold. Companies involved in the collection of the
majority of the gold exploration data since 1985 and prior to 2014 include: Thames Mining NL

Minerals NL (“Metana”) 1986‐1989; Sons of Gwalia Ltd (“SOG”) 1989, 1992‐2004; Pacmin
Mining Corporation (“Pacmin”) 1999, and Navigator Resources Ltd (“Navigator”) 2004‐2014.
KIN exploration data from 2014 to 2017 has been acquired predominantly from RC and some
diamond drilling.
The database could not be fully verified regarding the reliability and accuracy of a substantial
portion of the historical data, however the recent drilling by KIN has enabled comparison with
the historical data and there is no material differences observed of a negative nature.
Database checks conducted by KIN and others are within acceptable limits. There is missing
data, however it is regarded as minimal. It is not possible to identify errors that might have
occurred prior or during digital tabulation of historic (pre‐2004) data, however the amount of
historic data used in the resource estimation is minimal and the effect would not be material.
The logging data coded in the database uses at least four different lithological code systems,
a legacy of numerous past operators (Hunter, MPI, SOG & Navigator). Correlation between
codes is difficult to establish, however can be achieved with effort. Based on historical reports,
drill hole logging procedures appear consistent with normal industry practices of the time.
KIN has attempted to validate historical logging data and to standardise the logging code
system by incorporating the SOG and Navigator logging codes into one. This is an ongoing
process and is not yet completed.
The drilling by Navigator and KIN has been used to scrutinize and calibrate historic logging
data. This has enabled KIN to establish good geological control, which has been used to derive
the geological interpretations in current work.
Navigator uploaded the original assay files received from the labs via a database administrator
using Datashed to minimise loading errors. An export of the data was then used to create an
access database for use in Surpac.
In 2009, Runge Ltd (“Runge”) completed a mineral resource estimate report for the Bruno,
Lewis and Kyte deposits. Runge carried out database verification, which included basic visual
validation in Surpac and cross check queries in Microsoft Access (“Access”). Runge did not
report any significant issues with the database.
Since 2014, KIN geologists have conducted verification of historic drilling, assays, geological
logs and survey information against the digital database, and in the field, including reviewing
historic reports and visual confirmations of Surpac and Access databases. KIN have not
reported any significant issues with the database.
KIN has validated the database in Datashed and in Surpac prior to Resource estimation. These
processes checked for holes that have missing data, missing intervals, overlapping intervals,
data beyond end‐of‐hole, holes missing collar co‐ordinates, and holes with duplicate collar co‐
ordinates.
During2017,CM carried out an independent data verification. 18,608 assayrecords for KIN’s

2014‐2017 drilling programs were verified by comparing laboratory assay reports against the
database. 4 errors were found, which are not considered material and which represents only
0.01% of all database records verified for KIN’s 2014‐2017 drilling programs.
Site Visit KIN’s geological team have conducted multiple site visits including supervision and
management of drill programs within each of the Resource areas.
Dr Spero Carras (Competent Person) was involved in the Leonora area at the Harbour Lights
and Mertondale areas during the 1980s, and is familiar with the geology and styles of
mineralisation within the Leonora Project area. He revisited the Leonora area during 2017 to
review the projects, drilling, sampling and general geology.
Messrs Mark Nelson and Gary Powell (Competent Persons) also conducted site visits to the
resource areas, and they have independently reviewed drill core, existing open pits, surface
exposures, drilling and sampling procedures. Mr Nelson also collected representative rock
samples of mineralisation from the Bruno and Lewis pits for bulk density determination.
Geological
Interpretati
on
The Cardinia Project area is located 35km NE of Leonora in the central part of the Norseman‐
Wiluna Greenstone Belt, which extends for some 600 kilometres on a NNW trend across the
Archean Yilgarn Craton of Western Australia.
The regional geology comprises a suite of NNE‐North trending greenstones positioned within
the Mertondale Shear Zone (MZN) a splay limb of the Kilkenny lineament. The MSZ denotes
the contact between Archaean felsic volcanoclastics and sediment sequences in the west and
Archaean mafic volcanics in the east. Proterozoic dykes and Archaean felsic porphyries have
intruded the sheared mafic/felsic volcanoclastic/sedimentary sequence.
Locally within the Cardinia Project area, the stratigraphy consists of intermediate, mafic and
felsic volcanic and intrusive lithologies and locally derived epiclastic sediments, which strike
NNW with a sub‐vertical attitude. Structural foliation of the stratigraphy dips moderately to
the east.
At Bruno, Lewis Link and Lewis, primary gold mineralisation is typically characterised by finely
disseminated sulphides (pyrite), and spatially associated with increased shearing and
lithological contacts between mafic and felsic lithologies. Secondary gold mineralisation
occurs as supergene enrichment within the regolith, and characterized by iron oxides, after
sulphides, in the bleached, carbonated felsic units near the footwall dolerite/felsic contact.
The central Lewis area is dominated by sub‐vertical, NW trending, highly altered, strongly
weathered mafics and intercalated beds of carbonated felsic rocks and minor sediments
(including shales).
Mineralisation at Kyte is hosted within sheared and altered mafics, and is typified in the
weathered zone, by iron‐rich alteration, after sulphides.
In some areas, gold mineralisation is highly variable in the regolith. In these areas, closer
spaced drillingwas carried out toprovide a high level of confidence in the interpretations.
Dimensions The Bruno Lewis Link deposit has a strike of 1.4km (NW‐SE) and a width of 500m (NE‐SW). The
Bruno Lewis Link area includes a total of 87,493m of drilling. The drilling in the mineralized
area for Bruno Lewis Link includes 2 DD holes for 15m, 1,309 RC holes for 9,432m and 277 AC
holes for 1,808m.
The Lewis deposit has a strike of 1.2km NW and a width of 200m. The Lewis area includes a
total of 100,880m of drilling. The drilling in the mineralized area for Lewis includes 13 DD
holes for 219m, 1,858 RC holes for 18,831m and 160 AC holes for 1,275m.
The Kyte deposit has a strike of 600m NW and a width of 200m. The Kyte area includes a total
of 10,430m of drilling. The drilling in the mineralized area for Kyte includes 2 DD holes for
64m, 114 RC holes for 1,623m and 55 AC holes for 424m.

a. Topography based on drill collar data
b. Bottom of Oxidation (BOCO)
c.

d. Wireframes of pre‐existing pits and some waste dumps
31. CM carried out an Independent Review of the weathering surfaces and where necessary,
based on new drilling (both RC and diamond), geological relogging and bulk density
information, the surfaces were modified to reflect the additional information. Surface
topography was also adjusted due to new information obtained in an April 2017 drone‐
borne aerial photogrammetry survey.
32. Based on geology, statistical analysis and intersection selection, domainal shapes were
wireframed at a 0.3g/t nominal edge cut‐off grade. These domainal shapes could contain
values less than 0.3g/t within the wireframes although this was minimized to prevent
smoothing dilution being incorporated into the final models. The parameters used for
intersection selection as a guide for wireframing were 8m downhole for the Bruno Lewis
Link, Lewis area and 3m downhole for Kyte. The intersections could include internal
dilution. The longer intersections were chosen due to vertical drilling in the grade
controlled areas of the deposit and in the Link area.
33. In December 2016 CM carried out a very detailed analysis of the closely spaced drilled
grade control areas of Bruno Lewis Link, Lewis. The drillholes were on 8m x 5m spacing
and while it is clear that there is a component of supergene ore and depletion in the
deposit, it became apparent that grades could be correlated from level to level on a
structural basis, indicating that the supergene component of the ore is restricted to the
vicinity of definitive felsic/mafic contacts and other shear structures. This was the model
that was followed in the ensuing geological interpretation where use was also made of
the geological logging. Discussions were also held with the mine geologist who worked
on mining of the Lewis pit, who confirmed that control on the mineralisation was mostly
in a vertical sense with a component of supergene ore.
34. The wireframed shapes were audited by KIN geological staff who had previous experience
whilst working for Navigator. It is possible that there could be slightly more supergene
ore in the models than has been used in the current interpretation.
35. Historically mined volumes were removed from the model. These shapes were based on
historical workings obtained from KIN.
36. Each wireframe had an assigned strike,dipandplunge.

37. Compositing from the top of each shape was carried out at 1m within each wireframe.
The majority of composites (98%) were greater than 1m.

40. A breakdown of pre‐Resource volume for each shape was measured. This was to ensure
that modelling did not over dilute shapes due to block sizes being used.
41. The declustering program DECLUS (ISATIS) was used to produce the weights to be
assigned to each composite for statistical analysis.
42. For each shape a detailed set of weighted statistics was produced. Due to the size of the
Bruno Lewis Link, Lewis areas, modelling was carried out by breaking it into 3 distinct
zones based approximately on northings and drill density in the South (see Figure 1). The
first zone, the most northerly, which encompassed the Bruno Grade Control area and the
Link area was known as Bruno Lewis Link. The Lewis area was broken into 2 further zones.
A zone north of the Proterozoic dyke known as Lewis Grade Control and a zone south of
the Proterozoic dyke, known as South. Each of these zones was analysed independently
and then recombined for reporting purposes into 2 areas known as Bruno Lewis Link
(which is a combination of the Bruno Grade Control zone and the Link zone) and Lewis
(which is a combination of the Lewis Grade Control zone and the area to the south of this
shown as Lewis South) (see Figure 2). Based on the statistics, high grade cuts were
determined for every shape and the percentage metal cut was estimated for each zone
as shown in the below table:

The high percentage metal cut is due to a very high grade outlier of > 500g/t. If
this high grade is removed then the percentage metal cut is 6%. However it does
show the high grade potential of the southern area.

44. Where a data point belonged to 2 shapes the cut allocated was determined for each
domain and independently allocated.
45. Variograms were run for each domain using ISATIS. The variograms were of very poor
quality with the dowhole variograms being the basis of fitted models. Directional
variograms were produced for downhole, down dip, down plunge. Where the downhole
variograms were calculated on an individual hole basis, variograms were not normalized.
Variograms were normalized for down dip and plunge. Raw variograms were used in
subsequent work.
46. The Author, Dr. S. Carras had extensive experience in the Leonora Belt during the 1980's
and has had familiarity with the nature of the mineralisation. To overcome the "string
problem" which occurs in narrow vein structures where more than 2 samples are used
per drillhole, three estimations were produced, OK, Inverse Distance Squared (ID2) and
Inverse Distance Cubed (ID3). Distance weighting methods do not suffer from the "string
problem".
47. The following parameters were used in modelling OK, ID2 and ID3:

A minimum number of samples of 4 and a maximum number of samples of 32

The discretisation parameters were 1 x 1 x 2 for Bruno Lewis Link, Lewis and 2 x
2 x 2 for Kyte

A maximum of 2 samples per hole

Note: for blocks that did not meet these requirements, the parameters were
relaxed and the search radii were increased.

To minimize the striping effect created by estimation in narrow shapes, the
downhole search radii were increased.
48. The ranges of search and directions used were applied on a shape by shape basis. The
aim was to produce OK results for the majority of shapes where there had been
adequate data to produce meaningful variography. Small shapes where there was
inadequate data were estimated using distance weighting squared methodology rather
than OK.
49. The fundamental block size used was:

0.5m x 0.5m x

narrow.
50. Scatter plots were then produced which compared OK, ID2 and ID3 for the small blocks
for larger shapes.
51. The models were then visually checked on a section by section basis of block versus
drillholes and ID2 proved to be the best fit, which eliminated the "string problem".
52. The small blocks produced by ID2 were then composited to form medium (quarter) sized
blocks and panels. The block dimensions for the medium (quarter) sized blocks and panels

53. Plots were produced of frequency histograms in domains for point data and for blocks.
54. To check that the interpolation of the block model honoured the drill data, validation was
carried out comparing the interpolated blocks to the sample composite data. The
validation plots showed good correlation, thus the raw drill data was honoured by the
block model.
55. Volumes within wireframes were determined and these were then compared with the
block estimates of the volumes within those wireframes on a shape by shape basis to
ensure that volumes estimated were correct.
56. Classification was carried out using a combination of drillhole density, drillhole quality,
and geology as the guide.
57. Resources were estimated within an AUS$2,200 optimised pit shell provided by Entech
(Perth). The optimised pit shells provided a reasonable basis for defining that portion of
models that may have prospects for economic exploitation in the foreseeable future and
could therefore reasonably be declared as Open Pit Resources. (Optimisation used a
dilution of 5% and a recovery of 95%. This was minimal and was only used to define the
Resource not the Reserve. The Resources reported are undiluted and do not have an ore
loss applied.)

Mining has taken place in the Bruno pit in 2010 a year after the Runge resource estimation
was published. Recovery and head grade were above expectations. In summary, mining at
Bruno returned 100,000t @ 2.33g/t Au. Free dig at Bruno trial pit, lower than forecast mining
costs, clayey weathered regolith – easy digging, supergene mineralisation, head grade was
40% higher than expected (almost 1g/t Au), good gold recovery, mine cut‐off grade 0.85g/t
Au. The successful mining by Navigator at Bruno suggests that the mineral resource has a
reasonable prospect for eventual economic extraction by medium scale open pit mining
methods, taking into account current mining costs and metal prices and allowing for potential
economic variations. Mining also took place in the Lewis pit. Reconciliation studies showed
that more metal was returned than was in the estimate at the time. Recent samples taken for
bulk density in the Bruno pit (2017) indicate a far higher bulk density than had been previously
used and upgrades in mining may be a function of the bulk density. Successful past open pit
mining indicates there should be few issues with mining methodology.

In 2010, an estimated 100,000 tonnes of Bruno trial mining was completed with a reconciled
recovery of 95%. In 2016, an estimated 15,000 tonnes of trial mining from the Lewis Grade
Control area was processed through the Lakewood mill in Kalgoorlie and delivered a
recovery of 94%. In both cases the material mined was oxide showing that oxide material in
the Bruno Lewis Link, Lewis area is expected to have good recoveries.
In 2016 – 2017 KIN’s drilling program included a series of RC and DD drillholes to collect
samples for geotechnical and metallurgical testwork.
Metallurgical testwork in the Bruno Lewis Link area has shown metallurgical recoveries in
the mid‐nineties in oxide and in transition.
Lewis (south of the Proterozoic dyke) metallurgical testwork has shown metallurgical
recoveries of better than 90% in oxide and transition and low eighties for fresh. The lower
recoveries for fresh material was associated with the presence of a minor amount of
sulphides (e.g. pyrite, arsenopyrite). Further testwork at a finer grind size will be undertaken
to improve recoveries.
For the Kyte deposit, very high recoveries were achieved in the mid‐nineties for both oxide
and transition.

s
Mining at Bruno (100,000t) from the trial pit, generated a mullock/waste dump next to the
open cut. It was to industry standards. It is assumed that practices concerning waste rock and
process residual will meet accepted industry standards.
Two open pits and their associated waste rock landforms (i.e. Bruno and the Lewis Trial Pit)
are encompassed by the current mineral resource estimate work. The Kyte resource area has
not been subjected to any previous mining activity.
Historical mining at each of the open pit sites, including waste rock landforms have not
demonstrated any impacts that cannot be managed in normal operations. Studies completed
to date, on ore and waste characterisations for previous and potential mining and processing
operations, have not identified any potential environmental impacts that cannot be managed
by normal operations. In addition, Navigator’s environmental bonds lodged with the DMP for
the Bruno operations have since been returned to Navigator, following the rehabilitation of
those operations.
Bulk Density Prior to 2014, there have been numerous programs of bulk density testwork conducted by
several companies at different times on diamond drill core and/or RC drill chips for some of
the various deposits. Generally the testwork has not been conclusive, since the testwork
methodology has not been adequately described in the historical reports, or when it has, the
testwork itself was not carried out using an acceptable method to determine dry bulk density.
Often, when described, the testwork measured specific gravity, not bulk density, and in cases
where bulk density was reported, the moisture content was not taken into account.
In 2009 Navigator Resources Ltd submitted 54 half or whole diamond core samples to Amdel
Mineral Laboratories Ltd’s (“Amdel”) Kalgoorlie laboratory for bulk density determination by
the water immersion method. The core samples were a mixture of half core and whole core
samples ranging from 10cm to 30cm in length, and were taken at downhole intervals of
roughly every 2 to 3 metres. The samples were firstly weighed, oven dried overnight at 110°C,
and weighed again to determine moisture content. Those samples that were likely to absorb
water were then sealed, using hairspray, prior to immersion in water. It is not known what
proportion of samples were not sealed, however it is likely that only fresh, non‐porous
samples were not sealed.
In 2017, KIN carried out a diamond drilling program to include obtaining samples for bulk
density testwork. Five diamond drill holes were drilled into the major parts of mineralised
zones at Bruno Lewis Link and Lewis.
A total of 478 half or quarter core samples, of varying lengths (5‐20cm) were taken at
downhole intervals of roughlyevery1 metre. The samples were submitted to an independent

Classification was based on a combination of drillhole spacing, drillhole quality and confidence
in geological continuity. In general all deposits were drilled on the following nominal grids:
Bruno:

Grade Control: 8m x 5m

Link:
30m x 20m
Lewis:

Grade Control: 8m x 5m
South:

South:
20m x 20m

In general drillhole spacing of 20m x 20m resulted in mineralisation being classified as
Indicated.
Drillhole spacing generally increases with depth and as a result deeper mineralisation is mostly
allocated to the Inferred category.
The Mineral Resource estimate appropriately reflects the view of the Competent Person.
Audits and
Reviews
Navigator Resources had worked with Runge (2009) to produce estimates for the Cardinia
deposits using ordinary kriging. KIN personnel carried out audits and internal reviews of the
data, assay, survey, wireframes and geological interpretations used by CM. CM also carried
out detailed reviews of all data.

Discussion
of Relative
Accuracy
and
Confidence
Two areas, the Bruno Grade Control area and the Lewis Grade Control area have been drilled
on a very close spaced grid 8m x 5m.
While it is acknowledged that there is a supergene and depletion effect in the Cardinia area,
it is also apparent that there are major structural controls on the location of mineralisation.
These controls are largely associated with the contact between felsic and mafic rocks and
shear zones. Very small blocks have been used to model the very narrow shear structures.
The use of vertical drilling into zones where the dip may be 70 degrees or more to the east
can also constitute some cause for concern, however given the very close drilling grids in the
grade control areas the major concern would be in the Link zone. To overcome any potential
over valuation of the Link zone, as a result of the wider spaced mostly vertical drilling, only
very narrow structures have been interpreted where intersected by drilling. It is likely that
more narrow mineralised structures are present between the current drill pattern. Hence, it
is likely that the Link zone is potentially undervalued.
In the modelling process every attempt has been made to eliminate the "string effect"
problem associated with the estimation of narrow vein structures through the use of ordinary
kriging. This has been achieved through the use of distance weighting estimates correlated
back to ordinary kriging estimates. This method, although heuristic has been validated by
extensive review of the block models and the drillhole data.
Every attempt has been made in the modelling to reduce the smoothing effect which results
when using a low cut‐off grade to determine boundary positions and limit the amount of
dilution in the Resource so that it can be correctly diluted for Reserve.
In all high coefficient of variation orebodies, local estimation is very difficult to achieve due to
the high nugget effect of the gold. This means that small parcels of ore are difficult to estimate
without further information such as closer spaced grade control drilling.
Historic mining of the Bruno pit resulted in more metal than had been predicted. It is likely
that this was due to an understatement of the bulk density and cutting of high grades, which
was too severe. In the current estimates both the high grade cuts and bulk density values
have been raised.

SECTION 1 – Sample Techniques and Data

(Criteria in this section apply to all succeeding sections)

Criteria Commentary
Sampling
techniques
All sample data, subject of this report and used for resource estimation work, is obtained from
various drilling programs carried out since 1986. Data was obtained predominantly from Reverse
Circulation (RC) drilling, and to a lesser extent, diamond core (Diamond) drilling and Air Core
(Aircore) drilling.
There is limited exploration data available prior to 1986, where exploration for nickel was carried
out in the late 1960s and for base metals in the 1970s. During 1980‐1985, Townson Holdings Pty
Ltd (“Townson”) mined a small open pit over some old workings at the Rangoon prospect.
Companies involved in the collection of the majority of the gold exploration data since 1986 and
prior to 2014 include: Mt Eden Gold Mines (Aust) NL (also Tarmoola Aust Pty Ltd “MEGM”) 1986‐
2003; Pacmin Mining Corporation Ltd (“Pacmin”) 1998‐2001; Sons of Gwalia Ltd (“SOG”) 2001‐
2004, and Navigator Resources Ltd (“Navigator”) 2004‐2014.
Kin Mining Ltd (“KIN”) acquired the Cardinia Project in 2014.
HISTORIC SAMPLING (1986‐2014)
Drill samples were generally obtained from 1m downhole intervals and riffle split to obtain a 3‐
4kg representative sub‐sample, which were submitted to a number of commercial laboratories
for a variety of sample preparations methods, including oven drying (90‐110°C), crushing (‐2mm
to ‐6mm), pulverizing (‐75μm to ‐105μm), and generally riffle split to obtain a 30, 40 or 50 gram
catchweight for gold analysis, predominantly by Fire Assay fusion, with AAS finish. On occasions,
initial assaying have been carried out using Aqua Regia digest and AAS/ICP finish, with anomalous
samples re‐assayed by Fire Assay fusion and AAS/ICP finish.
Diamond Drilling
Half core (or quarter core) sample intervals varied from 0.3 to 1.4m, but were predominantly
taken over 1m intervals, or at geological contacts, whichever was least. The remaining core was
retained in marked core trays and stored in a secure yard for future reference. The only known
available drill core from these programs and stored at KIN’s Leonora Exploration Yard, are those
drilled by Navigator.
RC Drilling
The vast majority of Reverse Circulation (RC) drill samples were collected over 1m downhole
intervals from beneath a cyclone and then riffle split to obtain a sub‐sample (typically 3‐4kg).
After splitting, 1m sub‐samples were typically collected in pre‐numbered calico bags, and the 1m
sample rejects were commonly stored at the drill site in marked plastic bags, for future reference.
First pass sampling often involved collecting composite samples by using a scoop (dry samples)
or spear (wet samples) to obtain 3m or 4m composited intervals, with the single metre split sub‐
samples being retained at the drill site. If the composite sample assays returned anomalous
results, the single metre sub‐samples for the anomalous composite intervals were retrieved and
submitted for gold analysis.
Navigator obtained sub‐samples from wet samples using the spear method.
Data relating to historical wet samples is not available, however the number of wet samples
involved is considered to be relatively low, and not material.

80

Criteria Commentary
There are no sample rejects available from RC drilling prior to 2014. Most drill sites have been
rehabilitated and the sample bags removed and destroyed.
Aircore Drilling
The procedures for sampling of Aircore drilling is generally the same as for RC drilling, although
in earlier (pre‐2004) programs, the majority of the 1m samples were mostly stored directly on the
ground prior to sampling with a scoop. Assay results from these samples are not used for resource
estimation work, however they do sometimes provide a guide in interpreting geology and
mineralisation continuity.
When drilling under dry conditions, Aircore samples should be of a comparable quality to RC
samples, when implementing same sampling techniques, therefore Aircore sample assay results
were only used for resource estimation work if the 1m sub‐samples were obtained by riffle
splitting of the primary sample, prior to placing on the ground.
There are no sample rejects available from AC drilling prior to 2014. Most drill sites have been
rehabilitated and the sample bags removed and destroyed.
RAB Drilling
Sample return from Rotary Air Blast (RAB) drilling are collected from the annulus between the
open hole and drill rods, using a stuffing box and cyclone. Samples are usually collected at 1 metre
intervals and placed on the ground with 3‐4kg sub‐samples collected using a scoop or spear. Up‐
hole contamination of the sample is commonplace, therefore this type of drilling and sampling is
regarded as reconnaissance in nature and the samples indicative of geology and mineralisation.
The qualities of samples are not appropriate for resource estimation work and are only
sometimes used as a guide for interpreting geology and mineralisation.
KIN MINING (2014‐2017)
Diamond Drilling
Diamond drill core (HQ3) samples collected for analysis were longitudinally cut in half, and then
in quarters, using a powered diamond core saw blade centered over a cradle holding the core in
place. Core sample intervals varied from 0.2 to 1.25m, but were predominantly taken over 1m
intervals, or at geological contacts, whichever was least. The remaining core was retained in their
respective core trays and securely stored in KIN’s yard in Leonora for future reference.
RC Drilling
During drilling, sample return is passed through a cyclone and stored in a sample collection box.
At the end of each metre, the cyclone underflow is closed off, the underside of the sample box is
opened and the sample passed down through a riffle splitter.
All RC sub‐samples were collected over one metre downhole intervals and averaged 3‐4kg.
Sample reject from the riffle splitter were retained and stored in marked plastic bags, and located
near to each drillhole collar.
All drilling, sample collection and sampling handling procedures were conducted and/or
supervised by KIN geology personnel to high level industry standards. QA/QC procedures were
implemented during each drilling program to industry standards.
Analysis
Once received at the assay laboratory, diamond core and RC samples were oven dried (105‐
110°C), crushed (‐6mm & ‐2mm), pulverised (P85% ‐75μm) and split to obtain a representative
50 gram sample catchweight for gold only analysis using Fire Assay fusion with AAS finish.
COMMENT
For some earlier (pre‐2004) drilling programs, RC and Aircore samples were obtained at 1.5, 2 or
4 metre downhole intervals.
For resource estimation work,Diamond,RC and some Aircore drillingdata was used where

81

Criteria Commentary
appropriate. RAB drilling data was not used for resource estimation but was sometimes used as
an interpretative guide only. A small proportion of the 2m sample intervals, particularly for
Helens‐Rangoon, were used in the resource estimation, only where the sampling methods are
appropriate, and where they sit within the mineralisation interpretations.
Drilling
techniques
Numerous programs comprising various types of drilling have been conducted by several
companies since 1985. The Cardinia database encompasses the various deposits and prospects
within the Cardinia Project’s Helens and Rangoon areas, and consists of 1,077 drillholes for a total
46,753 metres, excluding RAB drilling, viz:
Diamond drilling:
17 drillholes
956 metres
RC drilling:
755 drillholes
36,231 metres
Aircore drilling:
305 drillholes
9,566 metres
HISTORIC DRILLING (1986‐2014)
Diamond Drilling
Diamond drilling was carried out using industry standard ‘Q’ wireline techniques, with the core
retrieved from the inner tubes and placed in core trays. Core sizes include NQ/NQ3 (Ø 45‐48mm)
and HQ/HQ3 (Ø 61‐64mm). At the end of each core run, the driller placed core blocks in the tray,
marked with hole number and depth. Core recovery was usually measured for each core run and
recorded onto the geologist’s drill logs.
RC Drilling
RC drilling used conventional reverse circulation drilling techniques, utilising a cross‐over sub,
until the late 1980s, when the majority of drilling companies started changing over to using face‐
sampling hammers with bit shrouds. Drill bit sizes typically ranged between 110‐140mm. Samples
obtained from conventional RC drilling techniques with cross‐over subs often suffered from down
hole contamination (e.g. smearing of grades), especially beneath the water table. Samples
obtained from RC drilling techniques using the face sampling hammer suffered less from down
hole contamination and were more likely to be kept dry beneath the water table, particularly if
auxiliary and booster air compressors were used. These samples are considered to be more
reliable and representative.
Aircore Drilling
Aircore drilling is a form of RC drilling, but generally utilizing smaller rigs and smaller air
compressors, compared to standard RC drill rigs of the times. Aircore bits are hollow in the centre,
with the kerf comprising cutting blades or ‘wings’ with tungsten‐carbide inserts. Drill bit
diameters usually range between 75‐110mm.
All Aircore drilling (100%) was conducted by Navigator utilising suitable rigs with appropriate
compressors (eg 250psi/600cfm). Aircore holes were drilled mostly into the weathered regolith
using ‘blade’ or ‘wing’ bits, until the bit was unable to penetrate further (‘blade refusal’), often
near to the fresh rock interface. Hammer bits were used only when it was deemed necessary to
penetrate harder rock types. Hole depths ranged from 4m to 78m, averaging approximately 30
metres.
RAB Drilling
RAB drilling is carried out using small air compressors (eg 250psi/600cfm) and drill rods fitted with
a percussion hammer or blade bit, with the sample return collected at the drillhole collar using a
stuffing box and cyclone collection techniques. Drillhole sizes generally range between 75‐
110mm.
KIN MINING (2014‐2017)
Diamond Drilling
Diamond drilling was carried out by contractor Orbit Drilling Pty Ltd (“Orbit Drilling”) with a truck‐
mounted Hydco 1200H drill rig, using industry standard ‘Q’ wireline techniques. Drill core (HQ3)
is retrieved from the inner tubes andplaced inplastic core trays and each core run depth recorded

82

Criteria Commentary onto core marker blocks and placed at the end of each run in the tray. Drillhole deviation was measured at regular downhole intervals, typically at 10m from surface, thence every 30m to bottom of hole, using electronic multi‐shot downhole survey tools (i.e. Reflex EZ‐TRAC or Camteq Proshot). Core orientation was obtained for each core run where possible, using electronic core orientation tools (e.g. Reflex EZ‐ACT) and the ‘bottom of core’ marked accordingly. RC Drilling RC drilling was carried out by Orbit Drilling’s truck‐mounted Hydco 350RC drill rigs with 350psi/1250cfm air compressor, with auxiliary and booster air compressors (when required). Drilling utilised mostly downhole face‐sampling hammer bits (Ø 140mm), with occasional use of blade bits for highly oxidized and soft formations. The majority of drilling retrieved dry samples, with the occasional use of the auxiliary and booster air compressors beneath the water table, to maintain dry sample return as much as possible.

Drillhole deviations were surveyed downhole, during drilling operations, using electronic multi‐ shot downhole tool (e.g. Reflex EZ‐TRAC). In some instances, drillholes were surveyed later in open hole. In the later drilling programs, downhole surveying was carried out inside a non‐ magnetic stainless steel (s/s) rod, located above the hammer. Providing the tool was located in the middle of the stainless steel rod, azimuth and dip readings were successfully recorded. A separate independent program of downhole deviation surveying was carried out to validate previous surveys, utilizing an electronic continuous logging survey tool (AusLog A698 deviation tool).

COMMENT
Historical reports indicate that drill core sizes were predominantly HQ/HQ3 or NQ/NQ3, however
database details are incomplete. Most historical reports recorded core recoveries, although these
details are not included in the database. Review of some historical reports indicate that core
recoveries were generally good, although recoveries were typically less in highly fractured zones
and some highly weathered mineralised zones in the transition and oxide zones, however this
information is not recorded in the supplied database.

RC drilling is the dominant drill type at all sites. RC drilling information is generally described in varying detail in historical reports to the DMP, including drilling companies used and drilling rig types, however it’s not all recorded in the database supplied. Review of the historical reports indicates that reputable drilling companies were typically contracted and the equipment supplied was of an acceptable standard for those times. During the 1990s, and 2000s, suitable large drill rigs with on‐board compressors were probably complimented with auxiliary and booster air compressors for drilling to greater depths and/or when groundwater was encountered. KIN’s

83

Criteria Commentary
drilling was conducted with modern rigs equipped with auxiliary and booster compressors and
face sampling hammers with bit diameters typically 140mm.
When drilling under dry conditions, Aircore samples should be of a comparable quality to RC
samples, when implementing same sampling techniques. Aircore drilling data was only used in
resource estimation work, where the in‐field and laboratory sampling methodologies was
considered appropriate and limited to a number of selected Navigator drillholes.
Drill sample
recovery
HISTORIC DRILLING (1986‐2014)
Diamond Drilling
Core recovery has been recorded in most drill logs for most of the diamond drilling programs
since 1985, but is not recorded in the supplied database. A review of some historical reports
indicates that generally core recovery was good with lesser recoveries recorded in zones of
broken ground and/or areas of mineralisation. Overall recoveries are considered acceptable for
resource estimation.
RC Drilling
There is limited information recorded for sample recoveries for historical RC and Aircore drilling.
However there has been an improvement in sample recoveries and reliability following the
introduction of face sampling hammers and improved drilling technologies and equipment, since
the mid‐1980s.
KIN MINING (2014‐2017)
Diamond Drilling
Core recovery was recorded for each run by measuring total length of core retrieved against the
downhole interval actually drilled.
Diamond core recoveries were recorded in the database. Independent field reviews by the
Competent Persons (SC & GP) in 2017 of the diamond drilling rig in operation and core integrity
at the drill sites, demonstrated that diamond drill core recoveries were being maximised by the
driller, and that core recoveries averaged >95%, even when difficult ground conditions were being
encountered.
RC Drilling
Integrity of each one metre RC sample is preserved as best as possible. At the end of each 1 metre
downhole interval, the driller stops advancing the rods, retracts from the bottom of hole, and
waits for the sample to clear from the bottom of the hole through to the sample collector box
fitted beneath the cyclone. The sample is then released from the sample collector box and passed
through the 3‐tiered riffle splitter fitted beneath the sample box. Sample reject is collected in
plastic bags, and a 3‐4kg sub‐sample is collected in pre‐marked calico bags for analysis. Once the
samples have been collected, the cyclone, sample collector box and riffle splitter are flushed with
compressed air, and the riffle splitter cleaned by the off‐sider using a compressed air hose, and if
necessary a scraper. This process is maintained throughout the entire drilling program to
maximise drill sample recovery and to maintain a high level of representivity of the material being
drilled.
RC drill sample recoveries are not recorded in the supplied database, however a review by the
Competent Person (GP) in May 2017 of RC drill samples stored in the field, and observations of
the two RC drilling rigs in operation, suggests that RC sample recoveries were mostly consistent
and very good, with the samples themselves being reliable and representative of the material
being drilled.
COMMENT
Due to the lack of detailed information in the database regarding historic (pre‐2014) Aircore and
RC drilling, no quantitative or semi‐quantitative impression of sample recovery or sample quality
is available. Given that much of the drilling at Cardinia was conducted by the same companies
and at the same times as that carried out for the Mertondale Project, where it is assumed to be
satisfactory given that the Mertondale deposits were mined in thepast,byopenpit methods,

84

Criteria Commentary
where the open pits were mined to their original design limits, based on the historical drill data.
This suggests that the amount of metal recovered was probably not grossly different from pre‐
mining drill data based expectations.
During Navigators drill programs wet samples were spear sampled instead of riffle split. This is
regarded as poor sampling procedure and these samples are regarded as unreliable however the
total number of wet samples is considered to be very low.
No indication of sample bias is evident nor has it been established. That is, no relationship has
been observed to exist between sample recovery and grade.
The amount of Aircore drilling data used in the Cardinia resource estimation process is low and
regarded as not material.
Logging HISTORIC DRILLING (1986‐2014)
The logging data coded in the database uses at least four different lithological code systems, a
legacy of numerous past operators (MEGM, Pacmin, SOG & Navigator). Correlation between
codes is difficult to establish, however it can be achieved with effort. Based on historical reports,
drill hole logging procedures appear consistent with normal industry practices of the time.
Navigator’s procedure for logging of diamond core included firstly marking of the bottom of the
core (for successful core orientations), core recovery, fractures per metre and RQD, lithology,
alteration, texture, mineralisation, weathering, and other features, and then marked up for
cutting and sampling.
Navigator RC and Aircore logging was entered on a metre by metre basis, recording lithology,
alteration, texture, mineralisation, weathering and other features. The information was entered
directly into hand held digital data loggers and transferred directly to the database, after
validation, to minimize data entry errors.
The entire length of all drillholes are logged in full from surface to bottom of hole.
Logging is qualitative on visual recordings of lithology, oxidation, colour, texture and grain size.
Logging of mineralogy, mineralisation and veining is quantitative.
Drill core photographs are only available for Navigator’s diamond drillholes.
KIN MINING (2014‐2017)
KIN’s logging of drill samples was carried out in the field (RC drilling) or at the Leonora Yard
(diamond core) and entered onto a portable computer, on a metre by metre basis for RC, and by
sample intervals and/or geological contacts for diamond core. Data recorded included lithology,
alteration, structure, texture, mineralisation, sulphide content, weathering and other features.
Drillhole collar coordinates, azimuth, dip, depth and sampling intervals are also recorded in the
drill logs in the field.
Several diamond drillholes were completed for geotechnical purposes and were independently
logged for structural data by geotechnical consultants. All diamond drill core has been
photographed, and currently stored at KIN’s yard in Leonora.
KIN geological personnel retrieved the core trays from the drill rig site and relocated them to
KIN’s yard in Leonora at the end of each day. Drill core was photographed in the field or at the
Leonora yard, prior to cutting using a diamond core saw to obtain quarter core samples for
analysis.
All information collected was entered directly into laptop computers or tablets, and transferred
to the database to be validated.
COMMENT
KIN has attempted to validate historical logging data and to standardize the logging code system
by incorporating the SOG and Navigator logging codes into one. This is an ongoing process and is
not yet completed.

85

Criteria Commentary
The level of logging detail is considered appropriate for exploration and to support appropriate
mineral resource estimation, mining studies and metallurgical studies.
Qualitative logging includes classification and description of lithology, weathering, oxidation,
colour, texture and grain size. Quantitative logging includes identification and percentages of
mineralogy, sulphides, mineralisation, veining, and in addition, logging of diamond drilling
included geotechnical data, RQD and core recoveries.
For the majority of historical drilling (pre‐2004), and all of the more recent drilling, the entire
length of drillholes have been logged from surface to ‘end of hole’. Diamond core logging is
typically logged in more detail compared to RC and Aircore drilling.
Sub‐
sampling
techniques
and sample
preparation
HISTORIC DRILLING (1986‐2014)
Historical reports for drilling programs prior to 2004, are not always complete in the description
of sub‐sampling techniques, sample preparation and quality control protocols.
Diamond Drilling
Diamond drill core (NQ/NQ3 or HQ/HQ3) samples collected for analysis were longitudinally cut in
half, and occasionally in quarters for the larger (HQ/HQ3) diameter holes, using a powered
diamond core saw blade centered over a cradle holding the core in place.
Core sample intervals varied from 0.3 to 1.4m, but were predominantly taken over 1m intervals,
or at geological contacts, whichever was least. The remaining core was retained in core trays.
Where historical reports do not describe the sampling protocol for sampling of drill core, it is
assumed that drill core was sampled as described above.
RC Drilling
Prior to 1996, limited historical information indicates most RC sampling was conducted by
collecting 1m samples from beneath a cyclone and passing through a riffle splitter to obtain a 3‐
4kg sub‐sample for analysis. RC sampling procedures are believed to be consistent with the
normal industry practices at the time. The vast majority of samples were dry and riffle split,
however spear or tube sampling techniques were used for wet samples.
Samples obtained from conventional RC drilling techniques with cross‐over subs often suffered
from down hole contamination, especially beneath the water table. Samples obtained from RC
drilling techniques using the face sampling hammer suffered less from down hole contamination
and were more likely to be kept dry beneath the water table, particularly if auxiliary and booster
air compressors were used. These samples are considered to be representative.
The vast majority of Reverse Circulation (RC) drill samples were collected at 1m downhole
intervals from beneath a cyclone and then riffle split to obtain a sub‐sample (typically 3‐4kg).
After splitting, 1m sub‐samples were typically collected in pre‐numbered calico bags, and the 1m
sample rejects were commonly stored at the drill site in marked plastic bags, for future reference.
First pass sampling often involved collecting composite samples by using a scoop (dry samples)
or spear/tube (wet samples) to obtain 3m or 4m composited intervals, with the single metre split
sub‐samples being retained at the drill site. If the composite sample assays returned anomalous
results, the single metre sub‐samples for the anomalous composite intervals were retrieved and
submitted for analysis.
Navigator obtained sub‐samples from wet samples using the spear or tube method.
Data relating to historical wet samples is not available, however the number of wet samples
involved is considered to be relatively low, and not material.
There are no sample rejects available from RC drilling prior to 2014. Most drill sites have been
rehabilitated and the sample bags removed and destroyed.
Navigator included standards, fields duplicate splits (since 2009), and blanks within each drill
sample batch, at a ratio of 1 for every 20 samples, with the number of standards being inserted
at a ratio of 1 for every 50 samples.

86

Criteria Commentary
Aircore Drilling
The procedures for sampling of Aircore drilling is generally the same as for RC drilling, although
in earlier (pre‐2004) programs, the majority of the 1m samples were mostly stored directly on the
ground prior to sampling with a scoop.
A variety of laboratories were used for analysis. Prior to 2009, duplicate samples were not
routinely collected and submitted from RC and Aircore drilling to the same laboratory
consequently overall sampling and assay precision levels can’t be quantified for that period. Since
2009, Navigator adopted a stricter sampling regime with the submission of duplicate samples at
a rate of 1 for every 50 primary samples.
While QC protocols were not always comprehensive, the results indicate that assay results from
Navigators exploration programs were reliable. Results from pre‐Navigator operators are
regarded as consistent with normal industry practices of the time.
KIN MINING (2014‐2017)
Diamond Drilling
Diamond drill core samples collected for analysis were longitudinally cut in half and quarters,
using a powered diamond core saw blade centered over a cradle holding the core in place. Core
sample intervals varied from 0.2 to 1.25m, but were predominantly taken over 1m intervals, or
at geological contacts, whichever was least. The remaining core was retained in their respective
core trays and stored in KIN’s yard for future reference.
All of KIN’s diamond drill core is securely stored at their Leonora Yard.
RC Drilling
All RC sub‐samples were collected over 1 metre downhole intervals and retained in pre‐marked
calico bags, after passing through a cyclone and riffle splitter configuration. The majority of RC
sub‐samples consistently averaged 3‐4kg. Sample reject from the riffle splitter were retained and
stored in plastic bags, and located near each drillhole site. When drilling beneath the water table,
the majority of sample returns were kept dry by the use of the auxiliary and booster air
compressors. Very few wet samples were collected through the riffle splitter, and the small
number is not considered material.
Field duplicates were taken at regular intervals at a ratio of 1:50 and assay results indicate that
there is reasonable analytical repeatability, considering the presence of nuggety gold.
COMMENT
All sub‐sampling techniques and sample preparation procedures conducted and/or supervised by
KIN geology personnel are to standard industry practice. Sub‐sampling and sample preparation
techniques used are considered to maximise representivity of the material being drilled. QA/QC
procedures implemented during each drilling program are to industry standard practice.
Samples sizes are considered appropriate for this style of gold mineralisation and is an industry
accepted method for evaluation of gold deposits in the Eastern Goldfields of Western Australia
Quality of
assay data
and
laboratory
tests
Numerous assay laboratories and various sample preparation and assay techniques have been
used since 1981. Historical reporting and descriptions of laboratory sample preparation, assaying
procedures, and quality control protocols for the samples from the various drilling programs are
variable in their descriptions and completeness.
HISTORIC DRILLING (1986‐2014)
For assay data obtained prior to 2001, the incomplete nature of the data results could not be
accurately quantified in terms of the data derived from the combinations of various laboratories
and analytical methodologies.
Since 1993, the majority of samples submitted to the various laboratories were typically prepared
for analysis firstly by oven drying, crushing and pulverizing to a nominal 85% passing 75µm.

first pass detection method, with follow up analysis by Fire Assay fusion and AAS/ICP finish. This
was a common practice at the time. Mineralised intervals were subsequently Fire Assayed (using
30, 40 or 50 gram catchweights) with AAS/ICP finish.
Approximately 15‐20% of the sampled Aircore holes may have been subject to Aqua Regia digest
methods only, however Aircore samples were predominantly within the oxide profile, where
aqua regia results would not be significantly different to results from fire assay methods.
Limited information is available regarding check assays for drilling programs prior to 2004.
During 2004‐2014, Navigator utilised six different commercial laboratories during their drilling
programs, however Kalgoorlie Assay Laboratories conducted the majority of assaying for
diamond, RC and Aircore samples using Fire Assay fusion on 40 gram catchweights and AAS/ICP
finish.
Since 2009 Navigator regularly include field duplicates, Certified Reference Material (CRM)
standards and blanks with their sample batch submissions to the laboratories at average ratio of
1 in every 20 samples. Sample assay repeatability, and blank and CRM standards assay results are
within acceptable limits.
KIN MINING (2014‐2017)
Sample analysis was conducted by SGS Australia Pty Ltd’s (“SGS”) Kalgoorlie and Perth
laboratories. Sample preparation included oven drying (105°C), crushing (‐6mm), pulverising
(P85% ‐75µm) and riffle split to obtain a 50 gram catchweight. Analysis for gold only was carried
out by Fire Assay fusion technique with AAS finish (SGS Lab Code FAA505).
KIN regularly insert blanks, field duplicate and CRM standards in each sample batch at a ratio of
1:20. This allows for at least one blank and one CRM standard to be included in each of the
laboratory’s fire assay batch of 50 samples. Field duplicate sample assay repeatability, blank
standards and CRM standards assay results are within acceptable limits for this style of gold
mineralisation.
SGS include blanks and CRMS as part of their internal QA/QC for sample preparation and analysis,
as well as regular assay repeats. Sample pulp assay repeatability, and internal blank and CRM
standards assay results are within acceptable limits.
COMMENT
The nature and quality of the assaying and laboratory procedures used are considered to be
satisfactory and appropriate for use in mineral resource estimations.
Fire Assay fusion or Aqua Regia digestion techniques were conducted on diamond, RC and Aircore
samples, with AAS or ICP finish.
Fire Assay fusion is considered to be a total extraction technique. The majority of assay data used
for the mineral resource estimations were obtained by the Fire Assay technique with AAS or ICP
finish. AAS and ICP methods of detection are both considered to be suitable and appropriate
methods of detection.
Aqua Regia is considered a partial extraction technique, where gold encapsulated in refractory
sulphides or some silicate minerals may not be fully dissolved, resulting in partial reporting of
gold content.
No other analysis techniques have been used to determine gold assays.
KIN’s ongoing QA/QC monitoring program identified one particular CRM that was returning
spurious results. Further analysis demonstrated that the standard was compromised and
subsequently removed and destroyed. A replacement CRM of similar grade was substituted into
the QA/QC program.
Verification

Verification of sampling and assaying techniques and results prior to 2004 has limitations due to
the legacy of the involvement of various companies, personnel, drilling equipment, sampling
protocols and analytical techniques at different laboratories, over a twenty year period.
In 2009,Runge Ltd(“Runge”)completed a mineral resource estimate report for the Cardinia

Project area, including the Helens and Rangoon deposits. Runge’s database verification included
basic visual validation in Surpac and field verification of drillhole positions in February 2009.
Runge did not report any significant issues with the database.
Since 2014, significant drill intersections have been verified by KIN’s company geologists during
the course of the drilling programs.
During 2017, Carras Mining Pty Ltd ("CM") carried out an independent data verification. 10,499
assay records for KIN’s 2014‐2017 drilling programs were verified by comparing laboratory assay
reports against the database. 6 errors were found, which are not considered material and which
represents only 0.015% of all database records verified for KIN’s 2014‐2017 drilling programs
COMMENT
There is always a risk with legacy data that sampling or assaying biases may exist between results
from different drilling programs due to differing sampling protocols, different laboratories and
different analytical techniques.
Repeated examination of historic reports on phases of diamond, RC and Aircore drilling have been
conducted from time to time. Assay results from KIN’s recent drilling are consistent with
surrounding information and as a result the information obtained from the various diamond, RC
and Aircore drilling programs (where sampling protocols are appropriate) have been accepted.
Recent (2014‐2017) RC and diamond drilling by KIN included some twinning of historical drillholes
at the Helens and Rangoon resource areas, comprising historic information. There is no material
difference between historical drilling information and the KIN drilling information. In the areas
that were not drilled with twin holes, the drill density is considered sufficiently close enough to
enable comparison with surrounding historic information, and there is no material difference of
a negative nature between historical drilling information and the KIN drilling information. KIN’s
diamond holes were drilled for metallurgical and geotechnical test work, and assay results for
these holes also show adequate correlation with nearby historical results.
Where sampling protocols are appropriate, diamond, RC and Aircore samples, are of equal
importance in the resource estimation process.
There has been no adjustments or calibrations made to the assay data recorded in the supplied
database.
Location of
data points
HISTORIC DATA (1986‐2014)
Several local grids were established and used by previous project owners. During the 1990s,
SOG transformed the surface survey data firstly to AMG and subsequently to MGA (GDA94
zone51).
Drilling was carried out historically using various local grids. Since 2004, All Navigators drill hole
collars were surveyed on completion of drilling in the Australian MGA94, Zone51 grid using RTK‐
DGPS equipment by licensed surveyors, with more than 80% of the pickups carried out by
independent contractors.
Almost all the diamond and at least 70% of Navigator‘s RC holes were downhole surveyed. Pre‐
Navigator, single shot survey cameras were used, with typical survey intervals of 30‐40 metres.
KIN MINING (2014‐2017)
KIN’s drill hole collars were located and recorded in the field by a contract surveyor using RTK‐
DGPS (with a horizontal and vertical accuracy of ±50mm). Location data was collected in the
GDA94 Zone51 grid coordinate system.
Downhole surveying during KIN’s drilling programs was predominantly carried out by the drilling
contractor. KIN recognised that some of the downhole survey data appeared to be spurious, and
commissioned an independent downhole surveying program by a survey contractor (BHGS,
Perth)to check several drillholes at Helens and Rangoon. The check surveyfound occasional

89

Criteria Commentary
spurious results with the initial surveys. This can be explained by the fact that when the drilling
company’s survey tool is run inside the drill rods, the tool’s sensors need to be located exactly in
the middle of the bottom stainless steel (s/s) RC rod to obtain accurate readings. Check readings
by KIN personnel at different locations within the s/s rod found that variation in azimuth can be
measured up to 2°, within 1 metre from the centre of the rod, and up to 10° further away from
the centre. The positioning of the tool by the drilling contractor is assumed to be within 1 metre
of the centre of the s/s rod for the majority of the drilling program. Therefore, given the nature
of the mineralisation and the shift in apparent position of up to 5 metres (for 2° variation) along
‘strike’ for open pit depths (<140 metres), the occasional errors are not considered material for
this resource estimation work.
In addition, if the downhole survey tool is located within 15 metres of the surface, there is risk of
influence from the drill rig affecting the azimuth readings. This was observed for the survey
readings, which include total magnetic intensity (TMI) measurements, where TMI is spurious for
readings taken at downhole depths less than 20 metres. These spurious readings are included in
the database, but are not used.
KIN supplied two digital terrain models (DTM) of the topography: one DTM constructed from drill
hole collar data, and the second from a recent aerial orthophotogrammetry survey. The two DTM
surfaces correlate sufficiently close and within acceptable limits for horizontal and vertical
control, and appropriate for resource estimations.
COMMENT
The accuracy of the drill hole collar and downhole data are located with sufficient accuracy for
use in resource estimation work.
Some historical Navigator drillhole collar positions at Helens and Rangoon have recently been
independently located and verified in the field, and checked against the database.
Considering the history of grid transformations and surviving documentation, there might be
some residual risk of error in the MGA co‐ordinates for old drillholes, however this is not
considered to be material for the resource estimations, subject of this report.
Azimuth data was historically recorded relative to magnetic north. Much of the historical drilling
data was recorded relative to magnetic north. Variation in magnetic declination for the Cardinia
Project area is calculated at +0.823° East (1985) to +1.301° East (2017), with a maximum variation
of +1.575° in 2005. The difference between true north and magnetic north, and the annual
variation in magnetic declination since 1985 is not significant, therefore magnetic north
measurements have been used, where true north data is unavailable, for all survey data used in
resource estimation processes.
Data
spacing and
distribution
Drill hole spacing patterns vary considerably throughout the Project area, and is deposit specific,
depending on the nature and style of mineralisation being tested.
Drill hole and sample interval spacing is sufficient to establish an acceptable degree of geological
and grade continuity appropriate for mineral resource estimations and classifications applied.
There has been no sample compositing, other than a few historical compositing of field samples
for some Aircore and RC samples to 1.5m, 2m, 3m, 4m and a few 5m intervals. The vast majority
(>90%) of primary assay intervals are 1 metre intervals for RC and Aircore samples, and
predominantly 1 metre intervals for core samples.
Orientation
of data in
relation to
geological
structure
The sheared Cardinia greenstone sequence displays a NNW to NW trend. The drilling and
sampling programs were carried out to obtain an unbiased location of drill sample data, generally
orthogonal to the strike of mineralisation.
Mineralisation is structurally controlled in sub‐vertical shear zones within the Cardinia area, with
a supergene component in the oxidised profile.
The vast majority of historical and KIN’s drilling is orientated at ‐60°/245° (WSW) and ‐60°/065°
(ENE), generally orthogonal to the strike of mineralisation.

Criteria Commentary
The chance of sample bias introduced by sample orientation is considered minimal. No
orientation sampling bias has been identified in the data thus far.
Sample
security
HISTORIC DRILLING (1986‐2014)
No sample security details are available for pre‐Navigator (pre‐2004) drill samples.
Navigator’s drill samples were collected from the riffle splitter in pre‐numbered calico bags at the
drill rig site. Samples were collected by company personnel from the field and transported to
Navigator’s secure yard in Leonora, where the samples were then batch processed (drillhole and
sample numbers logged into the database) and then packed into ‘bulkabag sacks’. The bulkabags
were tied off and stored securely in Navigator’s yard, until transporting to the laboratory. There
was no perceived opportunity for the samples to be compromised from collection of samples at
the drill site, to delivery to the laboratory.
KIN MINING (2014‐2017)
KIN’s RC drill samples were collected from the riffle splitter in pre‐numbered calico bags at the
drill rig site. The samples were then batch processed (drillhole and sample numbers encoded onto
a hardcopy sample register) in the field, and then transported and stacked into ‘bulkabag sacks’
at KIN’s secure yard in Leonora. The bulkabags were tied off and stored securely in the yard. The
laboratory’s (SGS) transport contractor was utilized to transport the bulkabags to the laboratory.
There was no perceived opportunity for the samples to be compromised from collection of
samples at the drill site, to delivery to the laboratory, where they were stored in their secure
compound, and made ready for processing.
On receipt of the samples, the laboratory (SGS) independently checked the sample submission
form to verify samples received, and readied the samples for sample preparation. SGS’s sample
security protocols are of industry acceptable standards.
Audits or
reviews
Historic drilling and sampling methods and QA/QC are regarded as not being as thoroughly
documented compared to today’s current standards. A review of various available historical
company reports of drilling and sampling techniques indicates that these were most likely
conducted to the best practice industry standards of the day.
A review of the Cardinia Project’s database, drilling and sampling protocols, and so forth, was
conducted and reported on by independent geological consultants Runge Ltd in 2009. Their
report highlighted issues with bulk density and QA/QC analysis of the database, which have since
been identified and addressed by Navigator and most recently by KIN during the 2017 drilling
campaign.
During 2017, CM have reviewed and carried out an audit on the field operations and database.
Drilling and sampling methodologies observed during the site visits are to today’s industry
standard. Similarly there were no issues identified for the supplied databases, which would be
considered material.
KIN is in the process of completing validation of all historical logging data and to standardise the
logging code system by incorporating the SOG and Navigator logging codes into one, and
converting all historical logging into the standardized code system. This is an ongoing process and
is not yet completed.
During the review, CM logged the oxidation profiles (‘base of complete oxidation’ or “BOCO”, and
‘top of fresh rock’ or “TOFR”) for each of the deposit areas, based on visual inspection of selected
RC drill chips from KIN’s recent drilling programs, and a combination of historical and KIN’s
drillhole logging, with final adjustments made with input from KIN geologists. The oxidation
profiles were used to assign bulk densities and metallurgical recoveries to the resource models.
Bulk density testwork in the past has been inconsistent with incorrect methods employed, to
derive specific gravity or in‐situ bulk density, rather than dry bulk density. Navigator (2009) and
recent KIN (2017) bulk density testwork was carried out using the water immersion method on
oven dried,coated samples to derive drybulk densities for different rock types and oxidation

profiles. This information has been incorporated into the database for resource estimation work.
CM conducted site visits during 2017 to the laboratory to validate the methodology.
Recent (2014‐2017) RC and diamond drilling by KIN include some twinning of historical drillholes
within the Cardinia Project area. In addition, KIN’s infill drilling density is considered sufficiently
close enough to enable comparison with surrounding historic information, and there is no
material difference of a negative nature between historical drilling information and the KIN
drilling information. KIN’s diamond holes were drilled for metallurgical and geotechnical test
work, and assay results for these holes also show good correlation with nearby historical results.
Drilling, Sampling methodologies and assay techniques used in these drilling programs are
considered to be appropriate and to mineral exploration industry standards of the day.

Exploration
done by
other parties
There is limited exploration data available prior to 1986, where exploration for nickel was carried
out in the late 1960s and for base metals in the 1970s. During 1980‐1985, Townson Holdings Pty
Ltd (“Townson”) mined a small open pit over some old workings at the Rangoon prospect.
Companies involved in the collection of the majority of the gold exploration data since 1986 and
prior to 2014 include: Mt Eden Gold Mines (Aust) NL (also Tarmoola Aust Pty Ltd “MEGM”) 1986‐
2003; Pacmin Mining Corporation Ltd (“Pacmin”) 1998‐2001; Sons of Gwalia Ltd (“SOG”) 2001‐
2004, and Navigator Resources Ltd (“Navigator”) 2004‐2014.
In 2009, Navigator commissioned Runge Limited (“Runge”) to complete a Mineral Resource
estimate for the Helens and Rangoon deposits. Runge reported a JORC 2004 compliant Mineral
Resource estimate, at a low cut‐off grade of 0.7g/t Au, totaling 1.45Mt @ 1.3 g/t au (61,700 oz Au),
comprising total Indicated Resources of 1.0Mt @ 1.4 g/t Au and total Inferred Resources of
0.446Mt @ 1.2 g/t Au.
KIN’s drilling is focused in areas hosting the Helens and Rangoon deposits together with the strike
extensions and historical drilling conducted by the above mentioned operators.
Geology The Cardinia Project area is located 35km NE of Leonora in the central part of the Norseman‐
Wiluna Greenstone Belt, which extends for some 600km on a NNW trend across the Archean
Yilgarn Craton of Western Australia.
The regional geology comprises a suite of NNE‐North trending greenstones positioned within the
Mertondale Shear Zone (MZN) a splay limb of the Kilkenny lineament. The MSZ denotes the contact
between Archaean felsic volcanoclastics and sediment sequences in the west and Archaean mafic
volcanics in the east. Proterozoic dykes and Archaean felsic porphyries have intruded the sheared
mafic/felsic volcanoclastic/sedimentary sequence.
Locally within the Cardinia Project area, the stratigraphy consists of intermediate, mafic and felsic
volcanic and intrusive lithologies and locally derived epiclastic sediments, which strike NNW with
a sub‐vertical attitude. Structural foliation of the stratigraphy dips moderately to the east.
At Helens and Rangoon, the stratigraphy comprises a sequence of intermediate‐mafic and felsic
volcanic lithologies and locally derived epiclastic sediments, intruded in places by narrow felsic
porphyry dykes. Carbonaceous shales often mark the mafic/felsic contact. These lithologies are
located on the western limb of the regionally faulted south plunging Benalla Anticline.
Primary mineralised zones at the Helens and Rangoon areas are north‐south trending with a sub‐
vertical attitude. Mineralisation is hosted predominantly in mafic rock units, adjacent to the felsic
volcanic/sediment contacts, where it is associated with increased shearing, intense alteration and
disseminated sulphides.
Minor supergene enrichment occurs within the mineralised shears within the regolith profile.
In some areas, gold mineralisation is highlyvariable in the regolith. In these areas,closer spaced

Data
Aggregation
methods
When exploration results have been reported for the resource areas, the intercepts are reported
as weighted average grades over intercept lengths defined by geology or lower cut‐off grades,
without any high grade cuts applied. Where aggregate intercepts incorporated short lengths of
high grade results, these results were included in the reports.
Since 2014, KIN have reported RC drilling intersections with low cut off grades of >= 0.5 g/t Au and
a maximum of 2m of internal dilution at a grade of <0.5g/t Au.
There is no reporting of metal equivalent values.
Relationship
Between
Mineralisation
widths and
intercept
lengths
The orientation, true width and geometry of the mineralised zones have been determined by
interpretation of historical drilling and verified by KIN’s drilling. The majority of drill holes are
inclined at ‐60° towards 245° (WSW), which is regarded as the optimum orientation to intersect
the target mineralisation, and some at ‐60° towards 065° (ENE). Since the mineralisation is steeply
dipping, drill intercepts are reported as downhole widths, not true widths. Accompanying dialogue
to reported intersections normally describe the attitude of the mineralisation.
Diagrams A plan and type sections for each resource area are included in the main body of the report.

Reporting
Public reporting of exploration results by KIN and past explorers for the resource areas are
considered balanced and included representative widths of low and high grade assay results.

Further work The potential to increase the existing resources is viewed as probable. Further work does not
guarantee that an upgrade in the resource would be achieved, however KIN intend to drill more
holes at the Helens and Rangoon resource areas with the intention of increasing the Cardinia
Project’s resources and converting the Inferred portions of the resources to the Indicated category.

Database
Integrity
All sample data, subject of this report and used for resource estimation work, is obtained from
various drilling programs carried out since 1986. Data was obtained predominantly from Reverse
Circulation (RC) drilling, and to a lesser extent, diamond core (Diamond) drilling and Air Core
(Aircore) drilling.
Companies involved in the collection of the majority of the gold exploration data since 1986 and
prior to 2014 include: Mt Eden Gold Mines (Aust) NL (also Tarmoola Aust Pty Ltd “MEGM”) 1986‐
2003; Pacmin Mining Corporation Ltd (“Pacmin”) 1998‐2001; Sons of Gwalia Ltd (“SOG”) 2001‐
2004, and Navigator Resources Ltd (“Navigator”) 2004‐2014.
KIN exploration data from 2014 to 2017 has been acquired predominantly from RC and some
diamond drilling.
The database could not be fully verified regarding the reliability and accuracy of a substantial
portion of the historical data, however the recent drilling by KIN has enabled comparison with
the historical data and there is no material differences observed of a negative nature.
Database checks conducted by KIN and others are within acceptable limits. There is missing data,
however it is regarded as minimal. It is not possible to identify errors that might have occurred
prior or during digital tabulation of historic (pre‐2004) data, however the amount of historic data
used in the resource estimation is minimal and the effect would not be material.
The logging data coded in the database uses at least four different lithological code systems, a
legacy of numerous past operators (MEGM, Pacmin, SOG & Navigator). Correlation between
codes is difficult to establish, however can be achieved with effort. Based on historical reports,
drill hole logging procedures appear consistent with normal industry practices of the time.
KIN has attempted to validate historical logging data and to standardise the logging code system
by incorporating the SOG and Navigator logging codes into one. This is an ongoing process and
is not yet completed.
The drilling by Navigator and KIN has been used to scrutinize and calibrate historic logging data.
This has enabled KIN to establish good geological control, which has been used to derive the
geological interpretations in current work.
Navigator uploaded the original assay files received from the labs via a database administrator
using Datashed to minimise loading errors. An export of the data was then used to create an
access database for use in Surpac.
In 2009, Runge Ltd (“Runge”) completed a mineral resource estimate report for the Cardinia
Project area, including the Helens and Rangoon deposits. Runge carried out database
verification, which included basic visual validation in Surpac and field verification of drillhole
positions in February 2009. Runge did not report any significant issues with the database.
Since 2014, KIN geologists have conducted verification of historic drilling, assays, geological logs
and survey information against the digital database, and in the field, including reviewing historic
reports and visual confirmations of Surpac and Access databases. KIN have not reported any
significant issues with the database.
KIN has validated the database in Datashed and in Surpac prior to Resource estimation. These
processes checked for holes that have missing data, missing intervals, overlapping intervals, data
beyond end‐of‐hole, holes missing collar co‐ordinates, and holes with duplicate collar co‐

a. Topography based on drill collar data
b. Bottom of Oxidation (BOCO)
c. Top of Fresh Rock (TOFR)
61. CM carried out an Independent Review of the weathering surfaces and where necessary,
based on new drilling (both RC and diamond), geological relogging and bulk density
information, the surfaces were modified to reflect the additional information. Surface
topography was also adjusted due to new information obtained in an April 2017 drone
survey.
62. Based on geology, statistical analysis and intersection selection, domainal shapes were
wireframed at a 0.3g/t nominal edge cut‐off grade. These domainal shapes could contain
values less than 0.3g/t within the wireframes although this was minimized to prevent
smoothing dilution being incorporated into the final models. A minimum of 5m downhole
at a 0.4g/t cut‐off grade was also used as a guide for wireframing. This could include internal
waste.
63. The wireframed shapes were audited by KIN geological staff who had previous experience
in the Cardinia area whilst working for Navigator.
64. Each wireframe had an assigned strike, dip and plunge.
65. Compositing from the top of each shape was carried out at 1m within each wireframe. The
majority of composites (98%) were greater than 1m.
66. The domainal shapes were passed into ISATIS Software with specified strike, dip and plunge.
67. The number of shapes used was as follows:

Variograms were normalized for down dip and plunge. Raw variograms were used in
subsequent work.
73. The Author, Dr. S. Carras had extensive experience in the Leonora Belt during the 1980's and
has had familiarity with the nature of the mineralisation. The shears are made up of
plunging en‐echelon structures. Three estimations were produced, OK, Inverse Distance
Squared (ID2) and Inverse Distance Cubed (ID3).
74. The following parameters were used in modelling OK, ID2 and ID3:

A minimum number of samples of 4 and a maximum number of samples of 32

The discretisation parameters were 1 x 1 x 2

A maximum of 2 samples per hole

Note: for blocks that did not meet these requirements, the parameters were
relaxed and the search radii were increased.

To minimize the striping effect created by estimation in narrow shapes, the
downhole search radii were increased.
75. The ranges of search and directions used were applied on a shape by shape basis. The aim
was to produce OK results for the majority of shapes where there had been adequate data
to produce meaningful variography. Small shapes where there was inadequate data were
estimated using an anisotropic distance weighting squared methodology rather than OK.
76. The fundamental block size used was:
Deposit
Small Blocks
Helens, Rangoon
Combined
1.25mN x 0.5mE x
1.25mRL
Small blocks were used to ensure adequate volume estimation where shapes were
narrow.
77. Scatter plots were then produced which compared OK, ID2 and ID3 for the small blocks.

78. The models were then visually checked on a section by section basis of block versus
drillholes and ID2 proved to be the best fit.
79. The small blocks produced by ID2 were then composited to form medium (quarter) sized
blocks and panels. The block dimensions for the medium (quarter) sized blocks and panels
were:

5mN x 5mE x
2.5mRL
10mN x 8mE x 5mRL
Quarter size blocks were used for reporting Resources.
80. Plots were produced of frequency histograms in domains for point data and for blocks.
81. To check that the interpolation of the block model honoured the drill data, validation was
carried out comparing the interpolated blocks to the sample composite data. The validation
plots showed good correlation thus the raw drill data was honoured by the block model.
82. Volumes within wireframes were determined and these were then compared with the
block estimates of the volumes within those wireframes on a shape by shape basis to
ensure that volumes estimated were correct.
83. Classification was carried out using a combination of drillhole density, drillhole quality, and
geology as the guide.
84. Resources were estimated within an AUS$2,200 optimised pit shell provided by Entech
(Perth). The optimised pit shells provided a reasonable basis for defining the portion of
models that may have prospects for economic exploitation in the foreseeable future and
could therefore reasonably be declared as Open Pit Resources. (Optimisation used a
dilution of 5% and a recovery of 95%. This was minimal and was only used to define the
Resource not the Reserve. The Resources reported are undiluted and do not have an ore
loss applied.)
85. Operating cost estimates developed by KIN indicated that a break even mill feed cut‐off
grade for deposits in the Cardinia area was likely to be 0.5g/t Au.
Moisture Tonnages and grades were estimated on a dry basis only. Bulk Density determinations of
diamond drill core included measurements of moisture content.

In 2017 KIN’s drilling program included a series of RC and DD drillholes to collect samples for

Metallurgical testwork in the Helens‐Rangoon area has shown metallurgical recoveries of mid‐
nineties in oxide, lower nineties in transition and in fresh material.
During the mining process, and where necessary, selective extraction of the graphitic shales is
envisaged to be possible so that successful segregation and quarantining of the shale material
can be achieved, so as to mitigate potential contamination of ore in the process plant.

s
No assumptions have been made regarding environmental factors.
Historical mining at the nearby Bruno deposit and Lewis trial pit sites, including waste rock
landforms have not demonstrated any impacts that cannot be managed in normal operations.
Studies completed to date, on ore and waste characterisations for previous and potential mining
and processing operations, have not identified any potential environmental impacts that cannot
be managed by normal operations.
Bulk Density Prior to 2014, there have been numerous programs of bulk density testwork conducted by
several companies at different times on diamond drill core and/or RC drill chips for the some of
the various deposits. Generally the testwork has not been conclusive, since the testwork
methodology has not been adequately described in the historical reports, or when it has, the
testwork itself was not carried out using an acceptable method to determine dry bulk density.
Often, when described, the testwork measured specific gravity, not bulk density, and in cases
where bulk density was reported, the moisture content was not taken into account.
In 2009 Navigator Resources Ltd submitted 144 half or whole diamond core samples to Amdel
Mineral Laboratories Ltd’s (“Amdel”) Kalgoorlie laboratory for bulk density determination by the
water immersion method. The core samples were a mixture of half core and whole core samples
ranging from 10cm to 30cm in length, and were taken at downhole intervals of roughly every 2
to 3 metres. The samples were firstly weighed, oven dried overnight at 110°C, and weighed again
to determine moisture content. Those samples that were likely to absorb water were then
sealed, using hairspray, prior to immersion in water. It is not known what proportion of samples
were not sealed, however it is likely that only fresh, non‐porous samples were not sealed.
In 2017, KIN carried out a diamond drilling program to include obtaining samples for bulk density
testwork. Six diamond drill holes were drilled into the major parts of mineralised zones at Helens
South, Helens North, Helens NE and Rangoon.
A total of 526 half or quarter core samples, of varying lengths (5‐20cm) were submitted by KIN
to an independent laboratory in Perth for bulk density determinations by the water immersion
method. The core samples were a mixture of half core and quarter core samples ranging from
5cm to 20cm in length, and were taken at downhole intervals of roughly every 1 metre. The
samples were firstly weighed, oven dried overnight at 110°C, and weighed again to determine
moisture content. The samples were then sealed, using hairspray, prior to immersion in water.
During the 2017 bulk density testwork and estimation process, Dr S Carras and Mr G Powell
(Consultant to CM) visited the laboratory and identified some improvements for consideration
in the bulk density determination process, particularly for small core pieces to give better
precision of measurements. The suggested improvements were implemented and precision
improved.
When estimating the bulk density for pieces of diamond drill core, it was found that the larger
sized samples gave more repeatable results and these were mostly used in assigning the bulk
densities.
As a result of the analysis of a combination of Navigator and KIN bulk density determination
results, the following bulk density parameters were used for the Helens and Rangoon areas:

Classificatio
n
Classification was based on a combination of drillhole spacing, drillhole quality and confidence
in geological continuity. In general all deposits were drilled on the following nominal grids (N‐
E):

Helens:
25m x 12.5m

Rangoon:
25m x 12.5m
In general drillhole spacing of 25m x 12.5m resulted in mineralisation being classified as
Indicated.
Drillhole spacing generally increases with depth and as a result deeper mineralisation is mostly
allocated to the Inferred category.
The Mineral Resource estimate appropriately reflects the view of the Competent Person.
Audits and
Reviews
Internal reviews have been conducted by the Competent Person who is obliged to review the
data geology/assay/survey/wire frames etc. this procedure is conducted as part of the normal
review process. The technical inputs, methodologies, parameters and results of the estimation
have been verified by the Runge (2009) and the Competent Person. This type of audit is
conducted as part of the normal review process.
Navigator Resources had worked with Runge (2009) to produce estimates for the Cardinia
deposits using ordinary kriging. KIN personnel carried out audits and internal reviews of the
data, assay, survey, wireframes and geological interpretations used by CM. CM also carried out
detailed reviews of all data.
Bulk density determination methodology was audited by S Carras and G Powell (Consultant to
CM) through visitation of the independent laboratory.
Discussion
of Relative
Accuracy
and
Confidence
KIN embarked on a program of infill drilling, including some close spaced drilling. The drilling
largely substantiated the position and tenor of mineralisation. It also validated the information
obtained from various drilling campaigns. (In some instances new results were much higher.)
In the modelling process every attempt has been made to eliminate the "string effect" problem
associated with the estimation of narrow vein structures through the use of ordinary kriging.
This has been achieved through the use of distance weighting estimates correlated back to
ordinary kriging estimates. This method, although heuristic has been validated by extensive
review of the block models and the drillhole data.
Every attempt has been made in the modelling to reduce the smoothing effect which results
when using a low cut‐off grade to determine boundary positions and limit the amount of dilution
in the Resource so that it can be correctly diluted for Reserve.
In all high coefficient of variation orebodies, local estimation is very difficult to achieve due to
the high nugget effect of the gold. This means that small parcels of ore are difficult to estimate
without further information such as closer spaced grade control drilling.

SECTION 1 – Sample Techniques and Data

(Criteria in this section apply to all succeeding sections)

Criteria Commentary
Sampling
techniques
All sample data, subject of this report and used for resource estimation work, is obtained from
various drilling programs carried out since 1989. Data was obtained predominantly from Reverse
Circulation (RC) drilling, and to a lesser extent diamond core (Diamond) drilling and Air Core
(Aircore) drilling.
There is limited exploration data available prior to 1989, where it is believed that exploration was
more focused on base metals, and not gold. Companies involved in the collection of the majority
of the gold exploration data since 1989 and prior to 2014 include: Triton Resources Ltd (“Triton”)
1989‐1999, Triton and Sons of Gwalia Ltd (“SOG”) 2000‐2004, and Navigator Resources Ltd
(“Navigator”) 2004‐2014.
Kin Mining Ltd (“KIN”) acquired the Raeside Project in 2014.
HISTORIC SAMPLING (1989‐2014)
For some historical drilling programs, RC and Aircore samples were composited at 2, 3, 4 or 5
metre downhole intervals, however the majority of drill samples were generally obtained from
1m downhole intervals and riffle split to obtain a 3‐4kg representative sub‐sample, which were
submitted to a number of commercial laboratories for a variety of sample preparations methods,
including oven drying (90‐110°C), crushing (‐2mm to ‐6mm), pulverizing (‐75μm to ‐105μm), and
generally riffle split to obtain a 30, 40 or 50 gram catchweight for gold analysis, predominantly by
Fire Assay fusion, with AAS finish. On occasions, initial assaying have been carried out using Aqua
Regia digest and AAS/ICP finish, with anomalous samples re‐assayed by Fire Assay fusion and
AAS/ICP finish.
Diamond Drilling
Half core (or quarter core) sample intervals varied from 0.1 to 1.0m, but were predominantly
taken over 1m intervals, or at geological contacts, whichever was least. The remaining core was
retained in marked core trays and stored in a secure yard for future reference. The only known
available drill core from this program (1 Diamond drill hole for 180.1m) and stored at KIN’s
Leonora Exploration Yard, are those drilled by Navigator.
RC Drilling
The vast majority of Reverse Circulation (RC) drill samples were collected over 1m downhole
intervals from beneath a cyclone and then riffle split to obtain a sub‐sample (typically 3‐4kg).
After splitting, 1m sub‐samples were typically collected in pre‐numbered calico bags, and the 1m
sample rejects were commonly stored at the drill site in marked plastic bags, for future reference.
First pass sampling often involved collecting composite samples by using a scoop (dry samples)
or spear (wet samples) to obtain 3m or 4m composited intervals, with the single metre split sub‐
samples being retained at the drill site. If the composite sample assays returned anomalous
results, the single metre sub‐samples for the anomalous composite intervals were retrieved and
submitted for gold analysis.
Navigator obtained sub‐samples from wet samples using the spear method.
Data relating to historical wet samples is not available, however the number of wet samples
involved is considered to be relatively low, and not material.
There are no sample rejects available from RC drilling prior to 2014. Most drill sites have been

rehabilitated and the sample bags removed and destroyed.
Aircore Drilling
The procedures for sampling of Aircore drilling is generally the same as for RC drilling, although
in earlier (pre‐2004) programs, the majority of the 1m samples were mostly stored directly on the
ground prior to sampling with a scoop. Assay results from these samples are not used for resource
estimation work, however they do sometimes provide a guide in interpreting geology and
mineralisation continuity.
When drilling under dry conditions, Aircore samples should be of a comparable quality to RC
samples, when implementing same sampling techniques, therefore Aircore sample assay results
were only used for resource estimation work if the 1m sub‐samples were obtained by riffle
splitting of the primary sample, prior to placing on the ground.
There are no sample rejects available from AC drilling prior to 2014. Most drill sites have been
rehabilitated and the sample bags removed and destroyed.
RAB Drilling
No Rotary Air Blast (RAB) drilling has been included in the Michelangelo or Leonardo resource
estimation.
KIN MINING (2014‐2017)
Diamond Drilling
Diamond drill core (HQ3) samples collected for analysis were longitudinally cut in half, and then
in quarters, using a powered diamond core saw blade centered over a cradle holding the core in
place. Core sample intervals varied from 0.2 to 1.15m, but were predominantly taken over 1m
intervals, or at geological contacts, whichever was least. The remaining core was retained in their
respective core trays and securely stored in KIN’s yard in Leonora for future reference.
RC Drilling
During drilling, sample return is passed through a cyclone and stored in a sample collection box.
At the end of each metre, the cyclone underflow is closed off, the underside of the sample box is
opened and the sample passed down through a riffle splitter.
All RC sub‐samples were collected over one metre downhole intervals and averaged 3‐4kg.
Sample reject from the riffle splitter were retained and stored in marked plastic bags, and located
near to each drillhole collar.
All drilling, sample collection and sampling handling procedures were conducted and/or
supervised by KIN geology personnel to today’s industry standards. QA/QC procedures were
implemented during each drilling program to today’s industry standards.
Analysis
Once received at the assay laboratory, diamond core and RC samples were oven dried (105‐
110°C), crushed (‐6mm & ‐2mm), pulverised (P85% ‐75μm) and split to obtain a representative
50 gram sample catchweight for gold only analysis using Fire Assay fusion with AAS finish.
COMMENT
For some historical drilling programs, RC and Aircore samples were composited at 2, 3, 4 or 5
metre downhole intervals. For resource estimation work, some RC field composite sample data
was used where appropriate.

Numerous programs comprising various types of drilling have been conducted by several

350psi/1250cfm air compressor, with auxiliary and booster air compressors (when required).
Drilling utilised mostly downhole face‐sampling hammer bits (Ø 140mm), with occasional use of
blade bits for highly oxidized and soft formations. The majority of drilling retrieved dry samples,
with the occasional use of the auxiliary and booster air compressors beneath the water table, to
maintain dry sample return as much as possible.
Drillhole deviations were surveyed downhole, during drilling operations, using an electronic
multi‐shot downhole tool (i.e. Camteq Proshot). In some instances, drillholes were surveyed later
in open hole. In the later drilling programs, downhole surveying was carried out inside a non‐
magnetic stainless steel (s/s) rod, located above the hammer. Providing the tool was located in
the middle of the stainless steel rod, azimuth and dip readings were successfully recorded.

COMMENT
Historical reports indicate that diamond drill core sizes were predominantly HQ/HQ3 or NQ/NQ3,
however database details are incomplete. Most historical reports recorded core recoveries,
although these details are not included in the database. Review of some historical reports indicate
that core recoveries were generally good, although recoveries were typically less in highly
fractured zones and some highly weathered mineralised zones in the transition and oxide zones,
however this information is not recorded in the supplied database.
RC drilling is the dominant drill type at all sites. RC drilling information is generally described in
varying detail in historical reports to the DMP, including drilling companies used and drilling rig
types, however it’s not all recorded in the database supplied. Review of the historical reports
indicates that reputable drilling companies were typically contracted and the equipment supplied
was of an acceptable standard for those times. During the 1990s, and 2000s, suitable large drill
rigs with on‐board compressors were probably complimented with auxiliary and booster air
compressors for drilling to greater depths and/or when groundwater was encountered. KIN’s
drilling was conducted with modern rigs equipped with auxiliary and booster compressors and
face sampling hammers with bit diameters typically 140mm.
When drilling under dry conditions, Aircore samples should be of a comparable quality to RC
samples, when implementing same sampling techniques. Aircore drilling data was only used in
resource estimation work, where the in‐field and laboratory sampling methodologies was
considered appropriate and limited to a number of selected Navigator drillholes.

Criteria Commentary
Core recovery has been recorded in most drill logs for most of the diamond drilling programs
since 1985, but is not recorded in the supplied database. A review of some historical reports
indicates that generally core recovery was good with lesser recoveries recorded in zones of
broken ground and/or areas of mineralisation. Overall recoveries are considered acceptable for
resource estimation.
RC Drilling
There is limited information recorded for sample recoveries for historical RC and Aircore drilling.
However there has been an improvement in sample recoveries and reliability following the
introduction of face sampling hammers and improved drilling technologies and equipment, since
the mid‐1980s.
KIN MINING (2014‐2017)
Diamond Drilling
Core recovery was recorded for each run by measuring total length of core retrieved against the
downhole interval actually drilled.
Diamond core recoveries were recorded in the database. Independent field reviews by the
Competent Persons (SC & GP) in 2017 of the diamond drilling rig in operation and core integrity
at the drill sites, demonstrated that diamond drill core recoveries were being maximised by the
driller, and that core recoveries averaged >95%, even when difficult ground conditions were being
encountered.
RC Drilling
Integrity of each one metre RC sample is preserved as best as possible. At the end of each 1 metre
downhole interval, the driller stops advancing the rods, retracts from the bottom of hole, and
waits for the sample to clear from the bottom of the hole through to the sample collector box
fitted beneath the cyclone. The sample is then released from the sample collector box and passed
through the 3‐tiered riffle splitter fitted beneath the sample box. Sample reject is collected in
plastic bags, and a 3‐4kg sub‐sample is collected in pre‐marked calico bags for analysis. Once the
samples have been collected, the cyclone, sample collector box and riffle splitter are flushed with
compressed air, and the riffle splitter cleaned by the off‐sider using a compressed air hose, and if
necessary a scraper. This process is maintained throughout the entire drilling program to
maximise drill sample recovery and to maintain a high level of representivity of the material being
drilled.
RC drill sample recoveries are not recorded in the supplied database, however a review by the
Competent Person (GP) in May 2017 of RC drill samples stored in the field, and observations of
the two RC drilling rigs in operation, suggests that RC sample recoveries were mostly consistent
and very good, with the samples themselves being reliable and representative of the material
being drilled.
COMMENT
Due to the lack of detailed information in the database regarding historic (pre‐2014) Aircore and
RC drilling, no quantitative or semi‐quantitative impression of sample recovery or sample quality
is available. Given that much of the drilling at Raeside was conducted by the same company
(Triton) and at the same time as that carried out for the nearby Forgotten Four deposit, where it
is assumed to be satisfactory given that the Forgotten Four deposit was mined by Triton to a
depth of 40‐45 metres by open pit methods. This suggests that the amount of metal recovered
was probably not grossly different from pre‐mining drill data based expectations.
During Navigators drill programs wet samples were spear sampled instead of riffle split. This is
regarded as poor sampling procedure and these samples are regarded as unreliable however the
total number of wet samples is considered to be very low.
No indication of sample bias is evident nor has it been established. That is, no relationship has
been observed to exist between sample recovery and grade.
No Aircore drilling data was used in the Raeside resource estimation process.

Criteria Commentary
Logging HISTORIC DRILLING (1989‐2014)
The logging data coded in the database uses at least three different lithological code systems, a
legacy of numerous past operators (Triton, SOG & Navigator). Correlation between codes is
difficult to establish, however it can be achieved with effort. Based on historical reports, drill hole
logging procedures appear consistent with normal industry practices of the time.
Navigator’s procedure for logging of diamond core included firstly marking of the bottom of the
core (for successful core orientations), core recovery, fractures per metre and RQD, lithology,
alteration, texture, mineralisation, weathering, and other features, and then marked up for
cutting and sampling. Several diamond drillholes were completed for geotechnical purposes and
were independently logged for structural data by geotechnical consultants. The diamond drill
core has been photographed, and currently stored at KIN’s yard in Leonora.
Navigator RC and Aircore logging was entered on a metre by metre basis, recording lithology,
alteration, texture, mineralisation, weathering and other features. The information was entered
directly into hand held digital data loggers and transferred directly to the database, after
validation, to minimize data entry errors.
The entire length of all drillholes are logged in full from surface to bottom of hole.
Logging is qualitative on visual recordings of lithology, oxidation, colour, texture and grain size.
Logging of mineralogy, mineralisation and veining is quantitative.
Drill core photographs are only available for Navigator’s diamond drillholes.
KIN MINING (2014‐2017)
KIN’s logging of drill samples was carried out in the field (RC drilling) or at the Leonora Yard
(diamond core) and entered onto a portable computer, on a metre by metre basis for RC, and by
sample intervals and/or geological contacts for diamond core. Data recorded included lithology,
alteration, structure, texture, mineralisation, sulphide content, weathering and other features.
Drillhole collar coordinates, azimuth, dip, depth and sampling intervals are also recorded in the
drill logs in the field. Four diamond drillholes were completed for geotechnical purposes and were
independently logged for structural data by geotechnical consultants.
KIN geological personnel retrieved the core trays from the drill rig site and relocated them to
KIN’s yard in Leonora at the end of each day. Drill core was photographed in the field or at the
Leonora yard, prior to cutting using a diamond core saw to obtain quarter core samples for
analysis.
All information collected was entered directly into laptop computers or tablets, and transferred
to the database to be validated.
COMMENT
KIN has attempted to validate historical logging data and to standardize the logging code system
by incorporating the SOG and Navigator logging codes into one. This is an ongoing process and is
not yet completed.
The level of logging detail is considered appropriate for exploration and to support appropriate
mineral resource estimation, mining studies and metallurgical studies.
Qualitative logging includes classification and description of lithology, weathering, oxidation,
colour, texture and grain size. Quantitative logging includes identification and percentages of
mineralogy, sulphides, mineralisation, veining, and in addition, logging of diamond drilling
included geotechnical data, RQD and core recoveries.
For the majority of historical drilling (pre‐2004), and all of the more recent drilling, the entire
length of drillholes have been logged from surface to ‘end of hole’. Diamond core logging is
typically logged in more detail compared to RC and Aircore drilling.

of sub‐sampling techniques, sample preparation and quality control protocols.
Diamond Drilling
Diamond drill core (NQ/NQ3 or HQ/HQ3) samples collected for analysis were longitudinally cut in
half, and occasionally in quarters for the larger (HQ/HQ3) diameter holes, using a powered
diamond core saw blade centered over a cradle holding the core in place.
Core sample intervals varied from 0.1 to 1.0m, but were predominantly taken over 1m intervals,
or at geological contacts, whichever was least. The remaining core was retained in core trays.
Where historical reports do not describe the sampling protocol for sampling of drill core, it is
assumed that drill core was sampled as described above.
RC Drilling
Prior to 1995, limited historical information indicates most RC sampling was conducted by
collecting 1m samples from beneath a cyclone and passing through a riffle splitter to obtain a 3‐
4kg sub‐sample for analysis. RC sampling procedures are believed to be consistent with the
normal industry practices at the time. The vast majority of samples were dry and riffle split,
however spear or tube sampling techniques were used for wet samples.
Samples obtained from conventional RC drilling techniques with cross‐over subs often suffered
from down hole contamination, especially beneath the water table. Samples obtained from RC
drilling techniques using the face sampling hammer suffered less from down hole contamination
and were more likely to be kept dry beneath the water table, particularly if auxiliary and booster
air compressors were used. These samples are considered to be representative.
The vast majority of RC drill samples were collected at 1m downhole intervals from beneath a
cyclone and then riffle split to obtain a sub‐sample (typically 3‐4kg). After splitting, 1m sub‐
samples were typically collected in pre‐numbered calico bags, and the 1m sample rejects were
commonly stored at the drill site in marked plastic bags, for future reference. First pass sampling
often involved collecting composite samples by using a scoop (dry samples) or spear/tube (wet
samples) to obtain 3m or 4m composited intervals, with the single metre split sub‐samples being
retained at the drill site. If the composite sample assays returned anomalous results, the single
metre sub‐samples for the anomalous composite intervals were retrieved and submitted for
analysis.
Navigator obtained sub‐samples from wet samples using the spear or tube method.
Data relating to historical wet samples is not available, however the number of wet samples
involved is considered to be relatively low, and not material.
There are no sample rejects available from RC drilling prior to 2014. Most drill sites have been
rehabilitated and the sample bags removed and destroyed.
Navigator included standards, duplicate splits, and blanks within each drill sample batch, at a ratio
of 1 for every 20 samples, with the number of standards being inserted at a ration of 1 for every
50 samples.
Aircore Drilling
The procedures for sampling of Aircore drilling is generally the same as for RC drilling, although
in earlier (pre‐2004) programs, the majority of the 1m samples were mostly stored directly on the
ground prior to sampling with a scoop.
A variety of laboratories were used for analysis. Prior to 2009, duplicate samples were not
routinely collected and submitted from RC and Aircore drilling to the same laboratory
consequently overall sampling and assay precision levels can’t be quantified for that period. Since
2009, Navigator adopted a stricter sampling regime with the submission of duplicate samples at
a rate of 1 for every 50 primary samples.
While QC protocols were not always comprehensive, the results indicate that assay results from
Navigators exploration programs were reliable. Results from pre‐Navigator operators are
regarded as consistent with normal industry practices of the time.

calico bags, after passing through a cyclone and riffle splitter configuration. The majority of RC
sub‐samples consistently averaged 3‐4kg. Sample reject from the riffle splitter were retained and
stored in plastic bags, and located near each drillhole site. When drilling beneath the water table,
the majority of sample returns were kept dry by the use of the auxiliary and booster air
compressors. Some wet samples were collected through the riffle splitter, and the small number
is not considered material.
Field duplicates were taken at regular intervals at a ratio of 1:50 and assay results indicate that
there is reasonable analytical repeatability, considering the presence of nuggety gold.
COMMENT
All sub‐sampling techniques and sample preparation procedures conducted and/or supervised by
KIN geology personnel are to standard industry practice. Sub‐sampling and sample preparation
techniques used are considered to maximise representivity of the material being drilled. QA/QC
procedures implemented during each drilling program are to industry standard practice.
Samples sizes are considered appropriate for this style of gold mineralisation and is an industry
accepted method for evaluation of gold deposits in the Eastern Goldfields of Western Australia
Quality of
assay data
and
laboratory
tests
Numerous assay laboratories and various sample preparation and assay techniques have been
used since 1981. Historical reporting and descriptions of laboratory sample preparation, assaying
procedures, and quality control protocols for the samples from the various drilling programs are
variable in their descriptions and completeness.
HISTORIC DRILLING (1989‐2014)
For assay data obtained prior to 1995, the incomplete nature of the pre‐1995 data results could
not be accurately quantified in terms of the data derived from the combinations of various
laboratories and analytical methodologies.
During 1995 Triton described the sample preparation process as hammer milling to ‐1mm, riffle
splitting to 0.5kg then pulverizing to a nominal 90% passing ‐75µm prior to Fire assay analysis.
In the initial exploration stages, Aqua Regia digest with AAS/ICP finish, was generally used as a
first pass detection method, with follow up analysis by Fire Assay fusion and AAS/ICP finish. This
was a common practice at the time. Mineralised intervals were subsequently Fire Assayed (using
30, 40 or 50 gram catchweights) with AAS/ICP finish.
Limited information is available regarding check assays for drilling programs prior to 2004.
During 2004‐2014, Navigator utilised six different commercial laboratories during their drilling
programs, however Kalgoorlie Assay Laboratories conducted the majority of assaying for
diamond, RC and Aircore samples using Fire Assay fusion on 40 gram catchweights and AAS/ICP
finish.
Post 2009 Navigator regularly included field duplicates, Certified Reference Material (CRM)
standards and blanks with their sample batch submissions to the laboratories at average ratio of
1 in every 20 samples.
KIN MINING (2014‐2017)

Criteria Commentary
Sample analysis was conducted by SGS Australia Pty Ltd’s (“SGS”) Kalgoorlie and Perth
laboratories. Sample preparation included oven drying (105°C), crushing (‐6mm), pulverising
(P85% ‐75µm) and riffle split to obtain a 50 gram catchweight. Analysis for gold only was carried
out by Fire Assay fusion technique with AAS finish (SGS Lab Code FAA505).
KIN regularly insert blanks, field duplicate and CRM standards in each sample batch at a ratio of
1:20. This allows for at least one blank and one CRM standard to be included in each of the
laboratory’s fire assay batch of 50 samples. Field duplicate sample assay repeatability, blank
standards and CRM standards assay results are within acceptable limits for this style of gold
mineralisation.
SGS include blanks and CRMs as part of their internal QA/QC for sample preparation and analysis,
as well as regular assay repeats. Sample pulp assay repeatability, and internal blank and CRM
standards assay results are within acceptable limits.
COMMENT
The nature and quality of the assaying and laboratory procedures used are considered to be
satisfactory and appropriate for use in mineral resource estimations.
Fire Assay fusion or Aqua Regia digestion techniques were conducted on diamond, RC and Aircore
samples, with AAS or ICP finish.
Fire Assay fusion is considered to be a total extraction technique. The majority of assay data used
for the mineral resource estimations were obtained by the Fire Assay technique with AAS or ICP
finish. AAS and ICP methods of detection are both considered to be suitable and appropriate
methods of detection.
Aqua Regia is considered a partial extraction technique, where gold encapsulated in refractory
sulphides or some silicate minerals may not be fully dissolved, resulting in partial reporting of
gold content.
No other analysis techniques have been used to determine gold assays.
KIN’s ongoing QA/QC monitoring program in general validated the assaying procedure used in
2017. One particular CRM was returning spurious results. Further analysis demonstrated that the
standard was compromised and subsequently removed and destroyed. A replacement CRM of
similar grade was substituted into the QA/QC program.
Verification
of_sampling
_and

assaying
Verification of sampling and assaying techniques and results prior to 2004 has limitations due to
the legacy of the involvement of various companies, personnel, drilling equipment, sampling
protocols and analytical techniques at different laboratories, over a fifteen year period.
Since 2014, significant drill intersections have been verified by KIN’s company geologists during
the course of the drilling programs.
An independent validation check by McDonald Speijers ("MS") (2009) resulted in 25 holes (13
being positioned at Michelangelo and Leonardo) being selected at random for which 21 original
hardcopy logs could be located and 20 corresponding lab reports. Correlation between this data
was good.
During 2017, an independent verification of 725 assay records for the 2014‐2017 drilling
programs completed by KIN have been verified by Carras Mining Pty Ltd (“CM”), with only one
discrepancy.
COMMENT
There is always a risk with legacy data that sampling or assaying biases may exist between results
from different drilling programs due to differing sampling protocols, different laboratories and
different analytical techniques.
Repeated examination of historic reports on phases of diamond, RC and Aircore drilling have been
conducted from time to time. Assay results from KIN’s recent drilling are consistent with
surrounding information and as a result the information obtained from the various diamond, RC
and Aircore drilling programs (where sampling protocols are appropriate) have been accepted.

110

Criteria Commentary
Recent (2014‐2017) RC and diamond drilling by KIN included some twinning of historical drillholes
within the Raeside Project area. The correlation between drill holes is regarded as good and in
other locations where the drill density is considered sufficiently close enough to enable
comparison with surrounding historic information, and there is no material difference between
historical drilling information and the KIN drilling information. KIN’s diamond holes were drilled
for metallurgical and geotechnical test work, and assay results for these holes also show good
correlation with nearby historical results.
Where sampling protocols are appropriate, diamond, RC and Aircore samples, are of equal
importance in the resource estimation process.
There has been no adjustments or calibrations made to the assay data recorded in the supplied
database.
Location of
data points
HISTORIC DATA (1989‐2014)
A local survey grid a mine grid were originally established in 1989 by Triton. During 2000‐2004,
SOG transformed the surface survey data firstly to AMG and subsequently to MGA (GDA94
zone51).
Drilling was carried out historically using various local grids. Since 2004, All Navigators drill hole
collars were surveyed on completion of drilling in the Australian MGA94, Zone51 grid using RTK‐
DGPS equipment by licensed surveyors.
Azimuth data was historically recorded relative to magnetic north. Much of the historical drilling
data was recorded relative to magnetic north. Variation in magnetic declination for the Raeside
Project area is calculated at +0.823° East (1985) to +1.301° East (2017), with a maximum variation
of +1.575° in 2005. The difference between true north and magnetic north, and the annual
variation in magnetic declination since 1985 is not significant. True north survey data was used
in resource estimation processes.
KIN MINING (2014‐2017)
KIN’s drill hole collars were located and recorded in the field by a contract surveyor using RTK‐
DGPS (with a horizontal and vertical accuracy of ±50mm). Location data was collected in the
GDA94 Zone51 grid coordinate system.
Downhole surveying during KIN’s drilling programs was predominantly carried out by the drilling
contractor.
If the downhole survey tool is located within 15 metres of the surface, there is risk of influence of
the drill rig affecting the azimuth readings. This was observed for the survey readings, which
include total magnetic intensity (TMI) measurements, where TMI is spurious for readings taken
at downhole depths less than 20 metres. These spurious readings are included in the database,
but are not used.
KIN supplied one digital terrain model (DTM) of the topography constructed from drill hole collar
data. A new DTM was supplied by KIN following a July 2017 aerial survey. The latter was used for
the resource estimation.
COMMENT
The accuracy of the drill hole collar and downhole data are located with sufficient accuracy for
use in resource estimation work
Considering the history of grid transformations and surviving documentation, there might be
some residual risk of error in the MGA co‐ordinates for old drillholes, however this is not
considered to be material for the resource estimations.
Azimuth data was historically recorded relative to magnetic north. Much of the historical drilling
data was recorded relative to magnetic north. Variation in magnetic declination for the Raeside

Drill hole and sample interval spacing is sufficient to establish an acceptable degree of geological
and grade continuity appropriate for mineral resource estimations and classifications applied.
There has been no sample compositing, other than a few historical compositing of field samples
for some Aircore and RC samples to 2m, 3m, 4m, and a few 5m and 6m intervals. The vast majority
(>90%) of primary assay intervals are 1 metre intervals for RC and Aircore samples, and
predominantly 1 metre intervals for core samples.
Orientation
of data in
relation to
geological
structure
The sheared Raeside greenstone sequence displays a NNW to NW trend. The drilling and sampling
programs were carried out to obtain an unbiased location of drill sample data, generally
orthogonal to the strike of mineralisation.
Mineralisation is structurally controlled in moderately dipping shear zones within the broader
Raeside Shear Zone, The majority of the gold mineralisation is confined to shear bound quartz
lodes/veining within a narrow carbonaceous shale that dips (‐40⁰ to ‐60⁰) to the east.
The vast majority of historical drilling is orientated ‐60°/280° (local grid west). KIN’s RC drilling is
predominantly orientated at ‐60°/225° (SW), generally orthogonal to the strike of mineralisation.
Diamond drilling by KIN, for geotechnical purposes, were orientated at ‐60° towards varying
azimuths including 225⁰, 045⁰, 200⁰ and 025⁰.
The chance of sample bias introduced by sample orientation is considered minimal. No
orientation sampling bias has been identified in the data thus far.
Sample
security
HISTORIC DRILLING (1989‐2014)
No sample security details are available for pre‐Navigator (pre‐2004) drill samples.
Navigator’s drill samples were collected from the riffle splitter in pre‐numbered calico bags at the
drill rig site. Samples were collected by company personnel from the field and transported to
Navigator’s secure yard in Leonora, where the samples were then batch processed (drillhole and
sample numbers logged into the database) and then packed into ‘bulkabag sacks’. The bulkabags
were tied off and stored securely in Navigator’s yard, until transporting to the laboratory. There
was no perceived opportunity for the samples to be compromised from collection of samples at
the drill site, to delivery to the laboratory.
KIN MINING
KIN’s RC drill samples were collected from the riffle splitter in pre‐numbered calico bags at the
drill rig site. The samples were then batch processed (drillhole and sample numbers encoded onto
a hardcopy sample register) in the field, and then transported and stacked into ‘bulkabag sacks’
at KIN’s secure yard in Leonora. The bulkabags were tied off and stored securely in the yard. The
laboratory’s (SGS) transport contractor was utilized to transport the bulkabags to the laboratory.
There was no perceived opportunity for the samples to be compromised from collection of
samples at the drill site, to delivery to the laboratory, where they were stored in their secure
compound, and made ready for processing.

112

Criteria Commentary
On receipt of the samples, the laboratory (SGS) independently checked the sample submission
form to verify samples received, and readied the samples for sample preparation. SGS’s sample
security protocols are of industry acceptable standards.
Audits or
reviews
Historic drilling and sampling methods and QA/QC are regarded as not being as thoroughly
documented compared to today’s current standards. A review of various available historical
company reports of drilling and sampling techniques indicates that these were most likely
conducted to the best practice industry standards of the day.
A review of the Raeside Project’s database, drilling and sampling protocols, was conducted and
reported on by independent geological consultants MS in 2009. Their report highlighted issues
with bulk density and QA/QC analysis of the database, which have since been identified and
addressed by Navigator and most recently by KIN.
During 2017, CM reviewed and carried out an audit on the field operations and database. Drilling
and sampling methodologies observed during the site visits are to today’s industry standard.
Similarly there were no issues identified for the supplied databases, which would be considered
material.
KIN is in the process of completing validation of all historical logging data and to standardise the
logging code system by incorporating the SOG and Navigator logging codes into one, and
converting all historical logging into the standardized code system. This is an ongoing process and
is not yet completed.
During the review, CM logged the oxidation profiles (‘base of complete oxidation’ or “BOCO”, and
‘top of fresh rock’ or “TOFR”) for each of the deposit areas, based on visual inspection of selected
RC drill chips from KIN’s recent drilling programs, and a combination of historical and KIN’s
drillhole logging, with final adjustments made with input from KIN geologists. The oxidation
profiles were used to assign bulk densities and metallurgical recoveries to the resource models.
Bulk density testwork in the past has been inconsistent with incorrect methods employed, to
derive specific gravity or in‐situ bulk density, rather than dry bulk density. Navigator (2009) and
recent KIN (2017) bulk density testwork was carried out using the water immersion method on
oven dried, coated samples to derive dry bulk densities for different rock types and oxidation
profiles. This information has been incorporated into the database for resource estimation work.
CM conducted site visits during 2017 to the laboratory to validate the methodology.
Recent (2014‐2017) RC and diamond drilling by KIN included twinning of historical drillholes
within the Raeside Project area, and where the infill drilling density is considered sufficiently close
enough to enable comparison with surrounding historic information, there is no material
difference between historical drilling information and the KIN drilling information. KIN’s diamond
holes were drilled for metallurgical and geotechnical test work, and assay results for these holes
also show good correlation with nearby historical results.
Drilling, Sampling methodologies and assay techniques used in these drilling programs are
considered to be appropriate and to mineral exploration industry standards of the day.

Exploration
done by
other parties
Gold was first discovered in the Leonora district about 1896 and it is likely that the first prospecting
activity in and around the Raeside Project area would have occurred at about that time. Initial
production from Raeside was a small underground operation in the early 1970’s when 60t @ 6.0
g/t Au was produced.
In 1989, Triton Resources Limited (Triton) entered into an arrangement with local prospectors
(Halloran and Prugnoli) to acquire some tenements in what is known as the Forgotten Four area.
The Triton Raeside Joint Venture mined the Forgotten Four (1990‐1992) to 45m depth. Production
statistics include:
1990: Mined and processed 6,280t @ 5.18 g/t Au (959oz) at the Tower Hill plant in Leonora with
91.7% recovery. 1992: Mined and processed 40,537t @ 4.14 g/t Au (4,993oz) at the Harbour Lights
plant in Leonora with 92.57% recovery. Finally a 2,822t parcel of ore~~(4~~.47 g/t Au~~)~~(389oz) was sold
to Harbour Lights. In 1992 remnant ore from low grade stockpiles totaling 6,200t @ 1.0 g/t Au
(199oz) was processed. Thus total production from the nearby Forgotten Four open cut yielded
55,839t @ 3.92 g/t Au (7,030oz) with an estimated recovery of approximately 92%. None of the
reported production figures have been confirmed from official Mines Department records.
The larger Raeside Project originated in 1992, when Triton (70%) formed a joint venture with Sabre
Resources N.L. (Sabre) (20%) and Copperwell Pty Ltd (Copperwell), a subsidiary of Cityview Energy
Corporation (10%). The three companies amalgamated their tenement holdings in the area and
the joint venture applied for additional tenements.
Until sometime in 1994 the project was managed on behalf of the joint venture by Westchester
Pty Ltd. Incomplete drilling records indicate that Westchester had been involved to some extent
in managing exploration in the area for Triton prior to 1992. After mid‐1994 Triton appears to have
taken over as project manager.
Before 1995, drilling programs were apparently dominated by first‐pass rotary air blast (RAB)
drilling, with local reverse circulation (RC) rotary or percussion drilling to follow up in places where
mineralisation was detected. Because of RAB drilling difficulties (clays and water) air core (AC)
drilling was subsequently adopted as the first‐pass method.
Triton’s drilling programs were suspended in June 1995 while a major review of results was
undertaken and a pre‐feasibility study was conducted. Drilling resumed in about April 1995.
Another economic evaluation of the project was undertaken by Triton in 1998‐1999 which
indicated that a stand‐alone operation was notpossible,but that theproject could be viable as a

SOG farmed in to the project in January 2000 and subsequently acquired full ownership. They
carried out limited amounts of predominantly RC drilling, aimed mainly at confirming previous
results from the Michelangelo deposit.
Navigator Resources Ltd (Navigator) acquired the Raeside project from SOG in September 2004.
Subsequent work by Navigator has focused mainly on other projects in the Leonora district, with
only very small amounts of additional drilling having been completed in the Raeside area.
In 2009, Navigator commissioned MS to complete a Mineral Resource estimate for the Raeside
deposits. MS reported a JORC 2004 compliant Indicated Mineral Resource estimate, at a low cutoff
grade of 0.7g/t Au, totaling 1.28Mt @ 2.68 g/t Au (111,000oz).
KIN acquired the Raeside Project from Navigator’s administrator in 2014.
Geology The Raeside Project area is located 10km ESE of Leonora in the central part of the Norseman‐
Wiluna Greenstone Belt, which extends for some 600km on a NNW trend across the Archean
Yilgarn Craton of Western Australia.
The regional geology comprises a sequence of Archaean greenstone lithologies. The area is
underlain by very poorly exposed rocks units. The gold deposits at Raeside occur within or close to
the margins of a large NW (320⁰) trendy body of dolerite within a sequence of sediments and
volcanoclastic rocks near the southern margin of porphyry intrusive. Most of the gold recovered
from mining the nearby Forgotten Four mine was from shear bound quartz vein stockworks or
sheeted veins and/or quartz carbonate veins within a narrow carbonaceous shale (dipping 40⁰‐60⁰
East) lying within a granophyric quartz dolerite and carbonate/sericite/sulphide altered wall rocks.
Gold mineralisation at Michelangelo is hosted by a uniform metamorphosed medium grained
dolerite. The deposit occurs on or above the basal sheared contact of the quartz dolerite. Four or
five extensive quartz vein structures dip at 30°‐40° to the northeast, extending over a strike length
of 575m with a total stratigraphic thickness of approximately 90m. The position of the footwall has
been roughly delineated however no other convincing geological boundaries are defined.
Gold mineralisation at Leonardo occurs mainly in a partly carbonaceous‐graphitic shale (coded as
generic metasediment) close to/adjacent to but above the quartz mafic contact. The
mineralisation dips 35°‐50° to the east however this ore body exhibits significant differences to the
other deposits. Initially the mineralisation at Leonardo is hosted in sedimentary rocks above the
quartz diorite. Secondly the mineralisation is associated with a zone of strong bleaching,
sericitisation and silicification, often up to +20m wide. The strike length of the steeply plunging
north main shoot is approximately 60m. Thirdly the gold mineralisation occurs within a relatively
linear shear zone that is traceable over 2km of strike; the shear contains significant mineralisation
in at least three other locations along strike.

When exploration results have been reported for the resource areas, the intercepts are reported
as weighted average grades over intercept lengths defined by geology or lower cut‐off grades,
without any high grade cuts applied. Where aggregate intercepts incorporated short lengths of
high grade results, these results were included in the reports.
Since 2014, KIN have reported RC drilling intersections with low cut off grades of ≥ 0.5 g/t Au and
a maximum of 2m of internal dilution at a grade of < 0.5g/t Au.
There is no reporting of metal equivalent values.

Relationship
Between
Mineralisation
widths and
intercept
lengths
The orientation, true width and geometry of the mineralised zones have been determined by
interpretation of historical drilling and verified by KIN’s drilling. The majority of historic drill holes
within the pit area are inclined at ‐60° towards 280° (west). Later drilling was undertaken on the
Raeside local grid, with a base line orientated to 330⁰ (north west). The KIN RC drilling is orientated
towards 225⁰ (SW), which is regarded as the optimum orientation to intersect the target
mineralisation. Since the mineralisation is moderately dipping (‐40⁰ to ‐60⁰ easterly), drill
intercepts are reported as downhole widths, not true widths. Accompanying dialogue to reported
intersections normally describe the attitude of the mineralisation.
Diagrams A plan and type sections for each resource area are included in the main body of the report.
Balanced
Reporting
Public reporting of exploration results by KIN and past explorers for the resource areas are
considered balanced and included representative widths of low‐ and high‐grade assay results.

Further work The potential to increase the existing resources is viewed as probable. Further work does not
guarantee that an upgrade in the resource would be achieved, however KIN intend to drill more
holes at Michelangelo and Leonardo with the intention of increasing the Raeside Project’s
resources and converting the Inferred portions of the resources to the Indicated category.

Criteria Commentary
Database
Integrity
All sample data, subject of this report and used for resource estimation work, is obtained from
various drilling programs carried out since 1989. Data was obtained predominantly from Reverse
Circulation (RC) drilling, and to a lesser extent, diamond core (Diamond) drilling and Air Core
(Aircore) drilling.
Companies involved in the collection of the majority of the gold exploration data since 1989 and
prior to 2014 include: Triton Resources Ltd (“Triton”) 1989‐1999, Triton and Sons of Gwalia Ltd
(“SOG”) 2000‐2004, and Navigator Resources Ltd (“Navigator”) 2004‐2014.
KIN exploration data from 2014 to 2017 has been acquired predominantly from RC and some
diamond drilling.
The database could not be fully verified regarding the reliability and accuracy of a substantial
portion of the historical (pre‐2004) data, however the recent drilling by KIN has enabled comparison
with the historical data and there is no material differences observed of a negative nature.
Database checks conducted by KIN and others are within acceptable limits. There is missing data,
however it is regarded as minimal. It is not possible to identify errors that might have occurred prior
or during digital tabulation of historic (pre‐2004) data, however the amount of historic data used in
the resource estimation is minimal and the effect would not be material.
The logging data coded in the database uses at least four different lithological code systems, a
legacy of numerous past operators (Triton, SOG & Navigator). Correlation between codes is difficult
to establish, however can be achieved with effort. Based on historical reports, drill hole logging
procedures appear consistent with normal industry practices of the time.
KIN has attempted to validate historical logging data and to standardise the logging code system by
incorporating the SOG and Navigator logging codes into one. This is an ongoing process and is not
yet completed.
The drilling by Navigator and KIN has been used to scrutinize and calibrate historic logging data.
This has enabled KIN to establish good geological control, which has been used to derive the
geological interpretations in current work.
Navigator uploaded the original assay files received from the labs via a database administrator using
Datashed to minimise loading errors. An export of the data was then used to create an access
database for use in Surpac.
In 2009, MS (“MS”) completed a mineral resource estimate report for the Raeside Project area,
including the Michelangelo and Leonardo deposits. MS carried out extensive database verification,
which included checks of surface survey positions, downhole surveys and assay data against original
records.
Since 2014, KIN geologists have conducted verification of historic drilling, assays, geological logs and
survey information against the digital database, and in the field, including reviewing historic reports
and visual confirmations of Surpac and Access databases. KIN have not reported any significant
issues with the database.
KIN has validated the database in Datashed and in Surpac prior to Resource estimation. These
processes checked for holes that have missing data, missing intervals, overlapping intervals, data
beyond end‐of‐hole, holes missing collar co‐ordinates, and holes with duplicate collar co‐ordinates.
During 2017, CM carried out an independent data verification. 725 assay records for KIN’s 2014‐
2017 drilling programs were verified by comparing laboratory assay reports against the database. 1
error was found, which is not considered material and which represents less than 0.01% of all
database records verified for KIN’s 2014‐2017 drilling programs.

Criteria Commentary Commentary
The database was continuously reviewed by CM during the 2017 resource estimation process.
Site Visit KIN’s geological team have conducted multiple site visits including supervision and management of
drill programs within each of the Resource areas.
Dr Spero Carras (Competent Person) was involved in the Leonora area at the Harbour Lights and
Mertondale areas during the 1980s, and is familiar with the geology and styles of mineralisation
within the Leonora Project area. He revisited the Leonora area during 2017 to review the projects,
drilling, sampling and general geology.
Messrs Mark Nelson and Gary Powell (Competent Persons) also conducted site visits to the resource
areas, and they have independently reviewed drill core, existing open pits, surface exposures,
drilling and sampling procedures.
Geological
Interpretation
The Raeside Project area is located 10km ESE of Leonora in the central part of the Norseman‐Wiluna
Greenstone Belt, which extends for some 600km on a NNW trend across the Archean Yilgarn Craton
of Western Australia.
The regional geology comprises a sequence of Archaean greenstone lithologies. The area is
underlain by very poorly exposed rocks units. The gold deposits at Raeside occur within or close to
the margins of a large NW‐trending (320⁰) body of dolerite within a sequence of sediments and
volcanoclastic rocks near the southern margin of a porphyry intrusive. Most of the gold recovered
from mining the nearby Forgotten Four mine was from shear bound quartz vein stockworks or
sheeted veins and/or quartz carbonate veins within a narrow carbonaceous shale (dipping 40⁰‐60⁰
East) lying within a granophyric quartz dolerite and carbonate/sericite/sulphide altered wall rocks.
Dimensions The Michelangelo deposit has a strike of 600m NW and a width of 100m. The Michelangelo area
includes a total of 32,536m of drilling. The drilling in the mineralized area for Michelangelo includes
16 DD holes for 225m and 320 RC holes for 3,419m.
The Leonardo deposit has a strike of 500m NW and a width of 150m. The Leonardo area includes a
total of 21,645m of drilling. The drilling in the mineralized area for Leonardo includes 8 DD holes
for 54m and 159 RC holes for 1,378m.

CM carried out an Independent Review of the weathering surfaces and where necessary, based
on new drilling (both RC and diamond), geological relogging and bulk density information, the

adjusted due to new information obtained in a July 2017 aerial survey.
Based on geology, statistical analysis and intersection selection, domainal shapes were
wireframed at a 0.3g/t nominal edge cut‐off grade. These domainal shapes could contain
values less than 0.3g/t within the wireframes although this was minimized to prevent
smoothingdilution beingincorporated into the final models. Theparameters used for

  • Criteria Commentary intersection selection were 3m downhole which equates to an approximate 2.5m bench height. The intersections could include 1m of internal dilution.

    1. The wireframed shapes were audited by KIN geological staff who had previous experience in the Raeside area whilst working for Navigator Resources Ltd. The interpreted mineralisation wireframes are consistent with those historically used at Raeside.
    1. Each mineralisation wireframe had an assigned strike, dip and plunge. 92. Compositing from the top of each shape was carried out at 1m within each wireframe. In Michelangelo the majority of composites (95%) were greater than 1m. In Leonardo the majority of composites (98%) were greater than 1m.
    1. The domainal shapes were passed into ISATIS Software with specified strike, dip and plunge. 94. The number of shapes used was as follows:

  1. A breakdown of pre‐Resource volume for each shape was measured. This was to ensure that modelling did not over dilute shapes due to block sizes being used.

  2. The declustering program DECLUS (ISATIS) was used to produce the weights to be assigned to each composite for statistical analysis.

  3. For each shape a detailed set of weighted statistics was produced. Based on the statistics, high grade cuts were determined for every shape and the percentage metal cut was estimated for each deposit as shown in the below table:

  1. Where a data point belonged to 2 shapes the cut allocated was determined for each domain and independently allocated.

  2. Variograms were run for each domain using ISATIS. The variograms were of very poor quality with the dowhole variograms being the basis of fitted models. Directional variograms were produced for downhole, down dip, down plunge. Where the downhole variograms were calculated on an individual hole basis, variograms were not normalized. Variograms were normalized for down dip and plunge. Raw variograms were used in subsequent work.

100.The following parameters were used in modelling OK, ID2 and ID3:

  • A minimum number of samples of 12 and a maximum number of samples of 32

  • The discretisation parameters were 2 x 2 x 2

  • A maximum of 2 samples per hole

  • Note: for blocks that did not meet these requirements, the parameters were relaxed and the search radii were increased.

  • To minimize the striping effect created by estimation in narrow shapes, the downhole search radii were increased.

101. The ranges of search and directions used were applied on a shape by shape basis. The aim
was to produce OK results for the majority of shapes where there had been adequate data to
produce meaningful variography. Small shapes where there was inadequate data were
estimated using an anisotropic distance weighting cubed methodology rather than OK.

106. To check that the interpolation of the block model honoured the drill data, validation was
carried out comparing the interpolated blocks to the sample composite data. The validation
plots showed good correlation thus the raw drill data was honoured by the block model.
107. Volumes within wireframes were determined and these were then compared with the block
estimates of the volumes within those wireframes on a shape by shape basis to ensure that
volumes estimated were correct.
108. Classification was carried out using a combination of drillhole density, drillhole quality, and
geology as the guide.
109. Resources were estimated within an AUS$2,200 optimised pit shell provided by Entech (Perth).
The optimised pit shells provided a reasonable basis for defining the portion of models that
may have prospects for economic exploitation in the foreseeable future and could therefore
reasonably be declared as Open Pit Resources. (Optimisation used a dilution of 5% and a

Mining
Factors or
Assumptions
Open pit mining will be the mining method employed going forward.
Metallurgical
Factors or
Assumptions
In 2017 KIN’s drilling program included a series of RC and DD drillholes to collect samples for
geotechnical and metallurgical testwork.
Metallurgical testwork in the Michelangelo‐Leonardo area has shown metallurgical recoveries of
mid‐nineties for oxide and transition and approximately 90% for fresh.
During the mining process, and where necessary, selective extraction of the graphitic shales is
envisaged to be possible so that successful segregation and quarantining of the shale material can
be achieved, so as to mitigate potential contamination of ore in the process plant.
Environmental
Factors
or
Assumptions
The Michelangelo and Leonardo deposits have not been subjected to any previous mining activity.
Historical mining at nearby Forgotten Four, including waste rock landforms have not demonstrated
any impacts that cannot be managed in normal operations.
Bulk Density Prior to 2014, there have been numerous programs of bulk density testwork conducted by several
companies at different times on diamond drill core and/or RC drill chips for the some of the various
deposits. Generally the testwork has not been conclusive, since the testwork methodology has not
been adequately described in the historical reports, or when it has, the testwork itself was not
carried out using an acceptable method to determine dry bulk density. Often, when described, the
testwork measured specific gravity, not bulk density, and in cases where bulk density was reported,
the moisture content was not taken into account.
In 2017, KIN carried out a diamond drilling program to include obtaining samples for bulk density
testwork at Michelangelo and Leonardo, where four diamond drill holes were drilled into the major
parts of mineralised zones.
A total of 231 half or quarter core samples, of varying lengths (5‐20cm) were submitted to an
independent laboratory in Perth for bulk density determinations by the water immersion method.
The core samples were a mixture of half core and quarter core samples ranging from 5cm to 20cm
in length, and were taken at downhole intervals of roughly every 1 metre. The samples were firstly
weighed, oven dried overnight at 110°C, and weighed again to determine moisture content. The
samples were then sealed, using hairspray, prior to immersion in water.
During the 2017 bulk density testwork and estimation process, Dr S Carras and Mr G Powell
(Consultant to CM) visited the laboratory and identified some improvements for consideration in
the bulk density determination process, particularly for small core pieces to give better precision of
measurements. The suggested improvements were implemented and precision improved.
When estimating the bulk density for pieces of diamond drill core, it was found that the larger sized
samples gave more repeatable results and these were mostly used in assigning the bulk densities.

121

Criteria Commentary
In general drillhole spacing of 25m x 15m, with some infill holes, resulted in mineralisation being
classified as Indicated.
Drillhole spacing generally increases with depth and as a result deeper mineralisation is mostly
allocated to the Inferred category.
The Mineral Resource estimate appropriately reflects the view of the Competent Person.
Audits and
Reviews
Internal audits were carried out on the geological interpretations and wireframes by KIN geologists.
Some data (e.g. geological logs) are scant; the assay data is historical and could not be
independently verified, however in 2017 KIN drilled 5 twinned drillholes. The drillholes provided a
very good validation to historical holes in the current database. In 2009, MS checked 25 holes
(mineralised intersections containing 1,141 sample records) selected at random and checked
against originals. The data correlation was not perfect but very acceptable (93% correlation)
considering the age of the data and the passing through different company history.
KIN personnel carried out audits and internal reviews of the data, assay, survey, wireframes and
geological interpretations carried out by CM for Michelangelo‐Leonardo. CM also carried out
reviews of data used for Michelangelo‐Leonardo.
Bulk density determination methodology was audited by S Carras and G Powell (Consultant to CM)
through visitation of the independent laboratory.
Discussion
of Relative
Accuracy and
Confidence
KIN embarked on a program of infill drilling, including twinning of 5 historical drillholes. The drilling
largely substantiated the position and tenor of mineralisation. It also validated the information
obtained from various drilling campaigns.
In the modelling process every attempt has been made to eliminate the "string effect" problem
associated with the estimation of narrow vein structures through the use of ordinary kriging. This
has been achieved through the use of distance weighting estimates correlated back to ordinary
kriging estimates. This method, although heuristic has been validated by extensive review of the
block models and the drillhole data.
Every attempt has been made in the modelling to reduce the smoothing effect, which results when
using a low cut‐off grade to determine boundary positions and limit the amount of dilution in the
Resource so that it can be correctly diluted for Reserve.
In all high coefficient of variation orebodies, local estimation is very difficult to achieve due to the
high nugget effect of the gold. This means that small parcels of ore are difficult to estimate without
further information such as closer spaced grade control drilling.

The mining method that is applied to the LGP
operations is conventional drill, blast, load and
haul. These methods are the same as many other
similar operations within the West Australian
Goldfields. The mining equipment applied to the
operation is sized to produce safe, efficient, and
productive mining. A medium sized mining fleet
has been selected with single ramp access with
passing bays.

Geotechnical considerations: The DFS
incorporates geotechnical reviews by Peter
O’Bryan & Associates who have sufficient data
from other areas to have adequate understanding
of the sites. This is confirmed by Mr Emmanuel
Deligeorges having visited all the mining areas.
Mr O’Bryan only visited the Cardinia sites. He has
broad experience in open pit mining in the general
Leonora area to determine the recommended wall
design parameters for the Feasibility Study. The
information used for the geotechnical guidance
included reviewing previously mined pits at
Mertondale, Bruno and the Lewis trial oxide pit
completed in July 2016. The information used for
the geotechnical study included current geological
interpretations; review of the open pit site areas;
wall angles and bench widths have been largely
determined by new geotechnical diamond drilling
and televiewing and adopted as per by Peter
O’Bryan recommendations; review of selected
diamond drill core photos and core in the Leonora
Core Farm.

The Mineral Resource used was completed by Carras
Mining in 2017 and reported to the ASX under JORC
2012 criteria in 30 August 2017

Given the narrow width of some areas of the ore
bodies, Entech Pty Ltd used its in-house proprietary
method to model the smallest mining unit (SMU) and
economically assess these mining unit. The SMU
defines the dimensions of the smallest practical mining
block that can be expected to be mined by open pit
methods.

Ore blocks smaller than the SMU are bulked out to the
appropriate width, resulting in a corresponding
reduction in grade. It also allows a waste skin of
unplanned dilution to be applied along the boundaries

Results have been identified through the use of the
following inputs:

unplanned dilution of 0.25 m (on both the
hangingwall and footwall)

cut-off grade $0/t (i.e. the shape must be profitable
considering mining and processing costs of all
diluting material)

smallest mining unit (6.25 m along strike (half
parent cell size), 1.5 m minimum width, 2.5 m
vertical height)

Material outside the ore boundaries are predominantly
the host rock with zero grade.

The resulting dilution is calculated and used for further
assessment and for the calculation of tonnes and grade
within the open pit schedules.

Inferred Mineral Resources
are utilised in mining
studies and the sensitivity
of the outcome to their
inclusion.

The global dilution for Cardinia, Mertondale and
Raeside mining districts are 9%, 16.1% (MSO
recovery) and 5.6% respectively.

The mining recovery is calculated from the difference
between Mineral Resource material above cut-off and
that contained within the identified mineable shapes.

The global mining recovery for Cardinia, Mertondale
and Raeside mining districts are 91.2%, 85.7% and
91.9% respectively.

Bench height is an important design factor when
considering the deposit attributes and the impact on
mining productivity. Based on a burden ranging
between 2.8 m and 3.6 m, a bench height of 5 m was
selected for the following reasons:

the ore body is medium width and small diameter
blast holes are desired

minimise the planned dilution where the deposit
experiences variances in dip and dip direction by
maintaining a short bench height

prevent large oversize; as a rule of thumb a bench
height much greater than the burden will prevent
large oversize, preferably a ratio closer to 2:1
(bench height to burden); large operations with
large benches achieve ratios above 3:1, however,
being a smaller operation, ratios close to two are
considered reasonable.

As the pits deepen, the area that is available for the
equipment to operate within will reduce. Typically,
there will be enough room for a truck to complete a
full turn-around until the point where the truck will
reverse into position to be loaded.

In these areas, a minimum 30 m mining width will be
maintained and is considered the smallest operating
width to conduct operations. At the end of the mine
life when a ‘goodbye cut’ is completed, a minimum 20
m mining width has been used.

Inferred Mineral Resources have been included in the
mine plan as its mined as part of the Inferred material
comprises 8% of the mine plan. The projects viability is
not dependent on the inferred material. Inferred
material is stockpiled and only processed in beginning

Metallurgical process data relating to each
respective deposit has been determined by a
review of historical production and laboratory
test work results ranging from 1987 -2017 and
processing performance statistics by
independent metallurgical consultant Greg
Wardell Johnson.

The recoveries used for this Ore Reserve
statement are based on independent test work
carried out by Independent Metallurgical
Operations (IMO) in 2017 and Ammtec Mineral
Consultants (2010)

Metallurgical data reviewed shows that the
proposed processing methods is expected to
produce high gold recovery in the oxide and
transitional material. Lower recoveries will be
experienced for fresh material at Mertons
Reward. The DFS delivered an overall average
metallurgical recovery of 92.5%.

Test work does not indicate material quantities
of preg-robbing for oxide and transition ores in
the mine plan. Where preg-robbing material is
encountered historical metallurgical testwork
(2010) showed that recoveries improved
significantly with the use of Activated Carbon. In
addition, preg-robbing black shales may be
mined separately from and stockpiled.

During the mining process, and where
necessary, selective extraction of the graphitic
shales is envisaged to be possible so that
successful segregation and quarantining of the
shale material can be achieved, so as to
mitigate potential contamination of ore in the
process plant.

Test work has shown the presence of

locally and being residential in Leonora.

New infrastructure required for the proposed
operation (in addition to mine-specific
infrastructure) includes:
• Diesel supplied power station

Costs
The derivation of, or
assumptions made,
regarding projected
capital costs in the
study.

The methodology used to
estimate operating costs.

The cost estimation strategy was based on securing
quotations or budget pricing from vendors for
dismantling of Lawlers processing plant, contract labour
work, equipment and associated mine infrastructure.
KIN’s strategy for the dismantling and re-
assembling/modification of the Lawlers processing
plant will be based on a “First principles build model”.
The model implies that KIN will be managing the entire
dismantling and re-assembling of the process plant and
infrastructure using the services of construction
supervisors, contract engineers, draftsman, surveyor
and purchasing officer. The costs evaluated by both
“COMO Engineering” and “Simulus Engineers &
Simulus Laboratories”. Capital costs are to ±15%.

Operating mining and G&A cost estimates have
been derived by Kin & Entech Pty Ltd. Operating
and capital costs to ±15% accuracy.

Mining cost estimates have been provided by Mining
Contractors and cost data from similar operations /
projects to an estimated accuracy of ±15%

Processing costs have been estimated by Kin and
reviewed by independent consultants SRK.
Operating costs to an accuracy of ±15%

Costs estimates are based on designs for open pit
mines, process plant (Lawlers) and site non-
process infrastructure and a combination of budget
quotations, factored estimates and cost data from
similar operations / projects. The derivation of cost
estimates is considered reasonable for Feasibility
Study purposes to an estimated accuracy of ±15%

Mine operating costs have been developed from first
principles by mining contractors and quotations to
provide a budget estimate of the mining schedule.
These costs have been used in the detailed DFS
financial model.

General and administration costs have been
estimated on a first principles basis and from
quotation from suppliers and contractors and
benchmarked to surrounding operations.

The project is located in the North-Eastern goldfields
region of Western Australia. The site has previously
been operated and the current project is a re-
establishment of previous mining, with the processing
plant proposed to be located near an existing well
maintained private road.

Heritage surveys have been previously conducted for
the property and infrastructure has been located to
not impact sites of significance.

All proposed mining and infrastructure areas lie within
granted Mining Leases.

There are no Native Title claims pending over the LGP

which extraction of the reserve
is contingent.

No Material naturally occurring risks have been
identified for the LGP. The environment is stable
with a long history of productive mining operations
that have not been affected by naturally occurring
events.

Kin is in possession of necessary legal agreements to
develop the operation. The requirements to maintain
agreements are transparent and well managed by the
company in consultation with the Western Australian
Government.

Gold is an easily traded commodity and does not
require any specific marketing arrangements.

There are reasonable grounds to expect that future
agreements and Government approvals will be
granted and maintained within the necessary
timeframes for successful implementation of the
project

There are no known material matters dependent on a
third party that require resolution for the LGP to be
developed

Mr Shane McLeay, the Competent person for this
Ore Reserve estimation, has overseen the work
undertaken in the 2017 DFS and considers that in
general, it is sufficiently detailed and relevant to the
deposit to allow Indicated resources scheduled within
the pit designs to be classified as Probable Ore
Reserves.

Discussion of
relative
accuracy/
confidence

Where appropriate a statement
of the relative accuracy and
confidence level in the Ore
Reserve estimate using an
approach or procedure
deemed appropriate by the
Competent Person. For
example, the application of
statistical or geostatistical
procedures to quantify the
relative accuracy of the
reserve within stated
confidence limits, or, if such
an approach is not deemed
appropriate, a qualitative
discussion of the factors which
could affect the relative
accuracy and confidence of the
estimate.

The statement should specify
whether it relates to global or
local estimates, and, if local,
state the relevant tonnages,
which should be relevant to
technical and economic
evaluation. Documentation
should include assumptions
made and the procedures
used.

Accuracy and confidence
discussions should extend to
specific discussions of any
applied Modifying Factors that
may have a material impact on
Ore Reserve viability, or for
which there are remaining
areas of uncertainty at the
current study stage.

It is recognised that this may
not be possible or appropriate
in all circumstances. These
statements of relative
accuracy and confidence of
the estimate should be
compared with production
data, where available.

The DFS document addresses the various modifying
factors to a DFS level of confidence and addresses
the modifying factors and assumptions made.

There is a degree of uncertainty associated with
geological estimates.

Accuracy of capital and operating cost estimates is
considered to be within ±15%, consistent with
accepted DFS standards. 18% contingency has been
allowed in the capital cost estimate to reflect the
degree of uncertainty of the estimate for each area.

The project is not yet operational and as such, no
recent production data exists at this time except for
the Bruno Mine (2010) and the Lewis Trial Pilot Scale
test carried out in 2016
