GOLD DIVISION
OVERVIEW
Metals X continued to consolidate its position as a gold producer with the end of the quarter marking the first year anniversary as a gold producer from its gold division strategy. Production guidance on acquisition was for a first full year of 150,000 per ounce at total costs of A$1,000 per ounce.
The first full year for the gold division yielded 180,361 ounces at total costs of sales of A$999 per ounce. Further, EBITDA generated from the first year of gold production was A$106.9 million.
Gold production for the current quarter was again above guidance of 35,000 ounces by 20.8% at 42,293 ounces.
At the Higginsville Gold Operations, the Company closed the Chalice Underground Mine during the quarter as previously forecast. The Company successfully commenced open pit mining at the Lake Cowen open pits to replace the Chalice ore source.
The South Kalgoorlie Operations continued to operate at full capacity on low grade stocks and intermittent toll processing of third party ores. Significant progress was made on a revised development plan that will see open pit mining recommence in the ensuing quarter as well as a re-start of the HBJ underground mine.
At the CMGP, detailed planning and the generation of budgets and works schedules are nearing completion. A number of immediate mining opportunities were drilled and evaluated and a revised plan of operations for a re-start of operations in mid 2015 is taking shape.
Diamond drilling at Rover 1 (copper-gold-bismuth) is underway with a focus on a resource upgrade below 600 m vertical depth and to gain additional data for geotechnical and shaft sinking studies.
Production guidance for the ensuing quarter for the gold division is 30,000 ounces at a total cost of A$1,100 per ounce. The lower production rate and increase in total cost reflects the buildup of open pit mining over the quarter which is initially of lower grade than the gold production from the Chalice Underground Mine.
HIGGINSVILLE GOLD OPERATIONS (HGO)
HGO consists of a modern 1.35 Mtpa capacity CIP plant, a 300 person village, the Trident Underground Mine, numerous open pits and requisite mine and process infrastructure.

Productivity and operational performance during the quarter was highlighted by excellent mine grade performance from the Trident Mine which offset lower production from the Chalice Mine. Continued issues with stoping at the Chalice Mine and lower reconciliations in the final development drives brought forward the closure of the mine, essentially 60,000 tonnes lower than expectated. The mine was completely closed and all stock was depleted by the end of the quarter. A complete writeoff of the remaining carrying values at the Chalice Mine occurred during the quarter.
QUARTERLY REPORT 2 FOR THE PERIOD ENDING 30 SEPTEMBER 2014
Ore from the Chalice Mine is being replaced with open pit ores from the Lake Cowan group of pits located approximately 10 km north-east of the process plant. Open pit mining commenced late in the quarter with the mining of the Louis Pit. These ores will complement the feeds from the Trident Mine and production rates will build during the current quarter.
HGO operating output for the quarter is summarised as follows:
| Higginsville Gold Operations | September 14 Quarter | Previous Quarter |
|---|---|---|
| Mine Production | ||
| Ore Tonnes (t) | 207,385 | 247,629 |

QUARTERLY REPORT 3 FOR THE PERIOD ENDING 30 SEPTEMBER 2014
HIGGINSVILLE GOLD OPERATIONS (HGO) (CONTINUED) EXPLORATION ACTIVITY
Exploration work at Trident has had a dual focus, with drilling targeted at both defining the internal grade distribution of the Artemis and Helios zones below the current mining front, and expanding the footprint of Trident Mineralisation beyond the boundaries of the current resource.
At Artemis, drilling was conducted beyond the southern boundary of the current resource and mine design. A best result of 0.7 m at 75.3 g/t in hole TUG2357 highlighted that the Artemis structure carries significant grade beyond what was thought to be the southernmost extent of economic mineralisation. Work over the current quarter will attempt to quantify the potential mining target in this area.
At Helios a previously undefined E Shear adjacent to active development has returned significant results over a strikelength of at least forty metres. This new zone of mineralisation is expected to contribute additional high-grade ounces to the production profile over the coming months without any additional capital expenditure. Best results returned from this E Shear include 2.6 m at 16.1 g/t from 16.8 m in hole TUG2316 and 2.7 m at 37.8 g/t from 16.3 m in hole TUG2320. In addition, Helios Core mineralisation within the current mining plan continues to return strong results in definition drilling. Some standout results this quarter include 8.1 m at 15.5 g/t from 80 m in hole TUG2307, 6.2 m at 6.8 g/t from 80.5 m in hole TUG2314 and 18 m at 5.2 g/t from 88.5 m in hole TUG2317.
The Poseidon zone which sits outside the current Trident resource and adjacent to existing Eastern Zone mining infrastructure has undergone initial testing this quarter. Pleasingly a series of strong results have been returned, providing significant encouragement for follow-up work in this area. Better results returned to date include 2.8 m at 10.1 g/t from 74 m in hole TUG2336, 2.1 m at 22.4 g/t from 69.5 m in hole TUG2332 and 2.8m at 6.5 g/t from 32.2 m in hole TUG2330.
Finally, a follow-up hole at the Ares (targetted up-dip and to the north of the current Artemis/Helios mining area) returned 8 m at 4.9 g/t Au. Work within the coming quarter will focus on better constraining the mineralised zone, which will allow for an initial economic assessment to be undertaken. This zone sits approximately 100 m from an existing developed area.
Significant drilling was conducted at the Josephine and Napoleon prospects in order to define additional ores to supplement the Louis Pit ore. Better results from this work include 19.1 m at 4.12 g/t from 42 m in hole LKCR252, 9.9 m at 4.30 g/t from 58 m in hole LKCR250 and 7.8 m at 9.77 g/t from hole LKCR258 all at Napoleon. It is expected that small open pits at both Josephine and Napoleon will be added to the current mining campaign at Louis.
Further afield, the Wills palaeo-channel resource underwent a last round of resource definition drilling. This will allow for finalisation of the pit design in anticipation of a significant campaign of palaeo-channel pit mining commencing in 2015. Better results from this work include 9 m at 6.34 g/t from 22 m in hole HIGA7133 and 7 m at 9.64 g/t from 23 m in hole HIGA7146.
QUARTERLY REPORT 4 FOR THE PERIOD ENDING 30 SEPTEMBER 2014
SOUTH KALGOORLIE OPERATIONS (SKO)
The SKO consists of a 1.2 Mtpa CIP plant and infrastructure. Numerous open pits and underground options have previously been mined within the tenement area since the late 1980’s.
The SKO operated predominantly on processing low grade stockpiles with intermittent toll processing of third party ores.
==> picture [524 x 159] intentionally omitted <==

Operational performance for the SKO business unit includes only those ores owned and processed by SKO, no physical toll processing production from ores owned by other parties are reported below. Revenues from toll processing are credited against the operating costs such that fiscal production from site as a business unit is reported. No mining was undertaken during the quarter. Physical output is summarised below:
| South Kalgoorlie Operations | September 14 Quarter | Previous Quarter |
|---|---|---|
| Mine Production | ||
| Ore Tonnes (t) | - | - |
| ROM Grade (g/t Au) | - | - |

QUARTERLY REPORT 5 FOR THE PERIOD ENDING 30 SEPTEMBER 2014
SOUTH KALGOORLIE OPERATIONS (SKO) (CONTINUED)
Total capital reinvestment into SKO for the quarter is summarised:
| South Kalgoorlie Operations | September 14 Quarter | Previous Quarter |
|---|---|---|
| Capital Mine Development ($M) | - | 0.36 |
| Exploration ($M) | 1.40 | 1.30 |
| Property Plant & Equipment ($M) | 0.44 | 0.05 |
In the ensuing quarter the plant feed will be a combination of SKO low-grade ore stocks and toll treatment of third party ores.
A number of small open pit feed sources have been identified, drilled and scheduled for open pit mining. These sources should see open pit mining recommence in the ensuing quarter and be processed in the March 2015 quarter. The staged approach to recommencing the HBJ Underground Mine advanced during the quarter with dewatering of the open pit being esentially completed. A new portal will be cut in the next quarter to intersect and allow rehabilitation of the old (existing) decline. Metals X expects to build a long-term ore supply from HBJ underground of approximately 400,000 tpa at 4-5 g/t Au on the doorstep of the process plant.
Additionally, a mine financing and profit sharing agreement was reached with Southern Gold during the quarter. This will see the Cannon Open Pit Mine and potentially an underground mine developed at Bulong. Under the agreement, Metals X’s staff will operate and manage the mine and the ore will be batch processed in parcels of approximately 40,000 tonnes through the Jubilee process plant. Revenue will firstly go to repay costs and the surplus will be split on a 50:50 basis.
Metals X is negotiating on a number of similar ventures with smaller operators in the Kalgoorlie region.
EXPLORATION ACTIVITY
Exploration drilling works at SKO during the quarter has been focussed on supporting the upcoming re-start of open pit mining. Open pit mining will initially will be concentrated in Locations 48 and 50, within 5 km of Metals X’s Jubilee Processing plant. Two of the three initial pits in this area, Peaceful Chief and Dusk underwent their final round of resource drilling. Better results returned from Peaceful Chief include 6 m at 3.01 g/t from 31 m in hole PCFRC025, 3 m at 9.75 g/t from 44 m in hole PCFRC032 and 3 m at 4.84 g/t Au from 57 m in hole PCFRC049. Better results returned from Dusk include 6 m at 3.58 g/t from 43 m in hole DSKRC043, 12 m at 1.78 g/t from 8 m in hole DSKRC044 and 12 m at 3.66 g/t from 11 m in hole DSKRC048. The third pit in the initial mining campaign, Mutooroo is undergoing final resource modelling, in preparation for optimisation, design and grade control in early November.
As reported in the previous quarter, the preparation of the existing Erebus and Fuji pits has continued to advance. These pits had previously terminated at a historical lease boundary that is now integrated into Metals X’s tenure. Initial positive drill results prompted follow-up drilling during the quarter, with recent results including 11 m at 3.31 g/t from 34 m in hole EBSRC075, 7 m at 5.12 g/t from 23 m in hole EBSRC096 and 11 m at 3.63 g/t from 43 m in hole EBSRC103. Based upon this drilling an initial resource model has been developed. Subsequent feasibility assessment has provided a pit design that will be grade controlled in early November in readiness for mining. Extensional drilling at Erebus continues, with the resource remaining open down-dip, and along-strike to the north.
Over the coming quarter exploration and resource development work at SKO will focus on: expanding the mining inventory in the Location 48/50 area; following up on the success achieved at Erebus; initial testing of the Trojan group of exploration targets will be undertaken in preparation for mining at the Trojan mining complex in 2015; ongoing geological development work at the large HBJ Underground Mine as it comes online from October.
QUARTERLY REPORT 6 FOR THE PERIOD ENDING 30 SEPTEMBER 2014
CENTRAL MURCHISON GOLD PROJECT (CMGP)
Metals X continued to advance its strategy to re-commence mining at the Central Murchison Gold Project.
The acquisition of the Meekatharra Gold Operations was completed in the previous quarter. These assets are now integrated into the existing Central Murchison Gold Project (CMGP), and works have commenced on a development strategy to bring the region into production in mid 2015.
The recently refurbished (and operated) 1.5–2.0 Mtpa process CIP plant and infrastructure provides an immediate process option for the ores in the region. As previously announced, the gold resource base covers the historic mineral production fields of Day Dawn, Cuddingwarra, Big Bell, Reedy, Yaloginda, Paddy’s Flat and Meekatharra North with a combined total resource of 7.85 million ounces.
==> picture [379 x 253] intentionally omitted <==
[Photo: Bluebird Plant 1.5–2.0 Mtpa]
The key objective for the CMGP is to re-establish the region as an underground mining hub whereby the major historic underground mines and prolific producers of Great Fingall, Golden Crown, Big Bell, Paddy’s Flat, Bluebird, Paddy’s Flat and Reedy mining centres are brought back into production.
The operational objective is to steadily access these underground mines on a staged basis over the ensuing years with an objective to achieve long-term sustainable production at a rate in excess of 200,000 oz per annum. The Bluebird mill will process a blended feedstock from all sources at an estimated rate of 2 million tonnes per annum at this point. In the build-up phase, smaller open pit mines will supplement underground development ores whilst full capacity is established over a 3 year period.
Metals X is close to completing its detailed development plans, costing and timing for the re-start which remains on track for a mid to late 2015 commencement.
On the exploration front, significant on-ground work commenced this quarter in support of the 2015 restart of operations at the CMGP.
Deep diamond drilling into the high-grade Great Fingall underground mine commenced, with the current holes designed to improve definition of the Great Fingall Reef at depth to assist in optimising the mine design. These holes are expected to be completed in November, with results available shortly thereafter.
The diamond rig will then shift onto drilling of underground targets at the Black Swan South and Rheingold prospects, both of which were prolific open pit mines with limited deeper evaluation.
QUARTERLY REPORT 7 FOR THE PERIOD ENDING 30 SEPTEMBER 2014
CENTRAL MURCHISON GOLD PROJECT (CONTINUED)
In the Yaloginda area, resource definition drilling was completed at the Batavia and Whangamata prospects to enable pit designs to be finalised. Results were not available at the end of the quarter. During the December quarter it is expected that grade control drilling for the first benches of all pits in the 2015 mining schedule will be completed, allowing ore block design and detailed short term scheduling to be undertaken well in advance of the proposed start of mining activities.
Diamond drilling will commence in the Paddy’s Flat area in October with an initial focus on underground targets at the high-grade Vivian – Consol’s mining area and from there progressing onto the Reedy mining centre.

QUARTERLY REPORT 8 FOR THE PERIOD ENDING 30 SEPTEMBER 2014
THE ROVER PROJECT (GOLD-COPPER-BISMUTH)
The Rover Project is an undercover repetition of the rich Tennant Creek Goldfield, 80 km to the north-east. Exploration to date has so far fully tested three blind targets within the project area. Each of which has defined significant mineralised IOCG (Iron Oxide Copper Gold) systems at Rover 1, Explorer 108 and Explorer 142 prospects.
Development works at Rover are focussed on the Rover 1 Prospect. Rover 1 is a virgin IOCG discovery and Metals X has previously announced a polymetallic Total Mineral Resource at Rover 1 (as at 30 June 2014) of 6.81 million tonnes at 1.74 g/t Au, 1.2% Cu, 0.14% Bi and 0.06% Co (1.22 Moz at 5.6 g/t gold equivalent).
The project area is proximal to a major infrastructure corridor adjacent to Central Australian Railway, gas pipeline and Stuart Highway.
Diamond Drilling commenced late in the quarter on an infill and extensional program for the Jupiter Deeps zone at Rover 1. At the quarter’s end the first hole defining the resource boundary in this area had been complete, with the margins of the ironstone and minor gold and chalcopyrite mineralisation (visual) successfully intersected. Assay results are yet to be recieved. A daughter hole/wedge targeting the centre of the ironstone down-plunge of the current Indicated resource is currently underway.
As previously advised, the Northern Territory Government, through the Geological Survey has awarded Metals X with co-funding of approximately $96,000 for the drilling of the Curiosity IP anomaly 36 km west-northwest of Rover 1. The co-funding has been awarded under the Geophysics and Drilling Collaborations program which is part of the NT Government’s CORE (Creating Opportunities for Resource Exploration) initiative which provides co-funding assistance for selected exploration drilling and geophysical acquisition projects in greenfields areas where there is a paucity of geological information. Drilling of this program commenced in mid October.
WARUMPI JOINT VENTURE (EARNING UP TO 80%)
The Warumpi Project is a grass roots exploration project in what is believed to be a paleo-proterozoic terrain equivalent to the prolific stratigraphy and epoch (1690-1610Ma) when the mega base metal mines of Broken Hill (1690Ma), Mt Isa (1654Ma), McArthur River (1640Ma) and Century (1610Ma) were formed. Metals X is a first mover in this virtually unknown and unexplored province.
Ground reconnaissance has discovered an outcropping gossan at the Huron Prospect with rock chip results at surface returning results up to 120g/t Ag, 9.89% Cu and 4.73% Zn (WR0343).
Further reconnaissance has revealed a cluster of gossanous outcrops with high anomalous base and precious metal results (silver, copper and zinc). Infill sampling surrounding this zone was completed during the quarter with results showing upto 182g/t Ag (WR0381), 7.72%Cu (WR0373) and 8.55% Zn (WR0351).
These results whilst early-stage, have provided encouragement for follow-up work, and as such, 3D IP and aerial magnetic surveys over the zone of anomalous surface responses have been planned for late October - early November.
QUARTERLY REPORT 9 FOR THE PERIOD ENDING 30 SEPTEMBER 2014
TIN DIVISION RENISON PROJECT (MLX 50%)
Productivity and operational performance continue to be in line with nameplate levels with higher head grades enabling a quarterly record of tin produced. Mine and processing outputs are summarised below:
| Renison Mine (100%) | Sept 2014 Quarter | Previous Quarter | Rolling 12 Months |
|---|---|---|---|
| Ore Tonnes (t) | 173,332 | 173,754 | 650,419 |
| ROM Grade (%Sn) | 1.56 | 1.43 | 1.48 |
| Tin Concentrator | |||
| Tonnes Processed (t) | 167,879 | 172,350 | 649,032 |
| Head Grade (%Sn) | 1.56 | 1.45 | 1.48 |
| Tail Grade (% Sn) | 0.48 | 0.47 | 0.47 |
| Tin Metal Produced (t) | 1,831 | 1,685 | 6,461 |
The operations have matured such that process capacity is no longer dictated by the mine output and increasing ore stocks have been building up ahead of the processing plant. The focus of mining is now on optimisation and grade maximisation whilst maintaining productivity.
The Renison tin concentrator plant continued to show steady performance with excellent availability, lower tin residues and significantly improved concentrate quality. Continuous improvement work programs are underway and are aimed at increasing plant productivity.
Whilst tin production was at record levels, lower revenue was received as the average tin price fell by A$1,200/t compared with the previous quarter. The key fiscal outcomes for the quarter attributable to Metals X’s 50% ownership of the Renison Project are summarised below:
| Fiscal Outcomes(MLX Share) | Sept 2014 Quarter | Previous Quarter | Rolling 12 Months |
|---|---|---|---|
| Imputed Revenue (A$) | 21.7 | 20.9 | 79.7 |
| Tin Price Received (A$/t Sn) | 23,659 | 24,855 | 24,560 |
| Cash Operating Cost (A$/t Sn) | 15,564 | 16,346 | 15,788 |
| Cash Cost of Sales (A$/t Sn) | 18,910 | 19,521 | 19,018 |
| Cash Operating Surplus (EBITDA $M) | 4.36 | 5.03 | 19.9 |
| Depreciation & Amortisation (A$/t Sn) | 1,821 | 2,201 | 2,316 |
| Total Cost of Sales (A$/t Sn) | 20,731 | 21,722 | 21,334 |
Capital re-investment at Renison has continued to slow as expected. A large stock of capitally and normally developed ore exists with mine, which bodes well for future production. Drilling activity during the quarter was focussed on the upgrading and infilling of known resources.
| Capital Re-investments(MLX Share) | Sept 2014 Quarter | Previous Quarter | Rolling 12 Months |

QUARTERLY REPORT 10 FOR THE PERIOD ENDING 30 SEPTEMBER 2014
NICKEL DIVISION
Metals X wholly owns the largest nickel project in Australia and one of the largest undeveloped nickel projects in the world today, the Wingellina Nickeliferous Limonite Project in the Central Musgrave Region of Western Australia.
The Wingellina Project is an intensely leached deposit of limonite (previously a dunite intrusive) enriched in nickel, iron and cobalt. Over the past decade, Metals X has consolidated outright ownership of the Wingellina layered intrusive complex. The latest move by Metals X in the region was to buy-out Rio Tinto’s interest in what was previously the Mt Davies JV, which it completed in 2013.

The key focus of the Nickel Division is to bring the Wingellina Nickel–Cobalt Project into production.
The Wingellina Mineral Resource estimate defines an ore body containing approximately 183 million tonnes of ore containing 1.8 million tonnes of contained nickel metal, 86 million tonnes of Fe203 and 139,000 tonnes of Cobalt metal. Significantly, over 91% of the resource is defined as a Probable mining reserve in accordance with the JORC code. The ore is very similar in style to Ambatovy in Madagascar (under development) and Moa Bay in Cuba, where Sherritt Gordon developed and have successfully operated High Pressure Acid Leach (HPAL) for over 50 years.
Wingellina is only one of many areas where nickeliferous limonites exist within the Central Musgrave Project, and is the only one to have been extensively drilled to date. In 2011 Metals X completed a drilling program at its Claude Hill Prospect, another known occurrence located approximately 25 km to the east of Wingellina. This first reconnaissance program defined a further Inferred Resource (JORC) of 33 million tonnes grading 0.81% Ni, 0.07% Co and 39% Fe2O3. Many other areas remain to be tested.
Metals X engaged industry experts to complete a feasibility study (+/-25%) in 2009 which concluded:
-
A robust project development with a minimum 40 year mine life at an average annual production rate of 40,000 t of nickel and 3,000 t of cobalt.
-
At a nickel price of US$20,000/t nickel, US$40,000/t cobalt and an A$/US$ exchange rate of 0.85, an estimated Project NPV(8%) of $3.4 Billion was determined.
-
A production cost of US$3.34/lb after cobalt credits.
-
Capital cost estimates were put at approximately A$2.5 billion and have recently been reconfirmed at this level (2013).
QUARTERLY REPORT 11 FOR THE PERIOD ENDING 30 SEPTEMBER 2014
PREVIOUS DEVELOPMENT PROPOSALS AT WINGELLINA
Metals X entered into a Memorandum of Undestanding (MOU) with Samsung C&T in September 2012 to work together to bring the massive Wingellina Ni–Co Project into production. Under the MOU, Metals X will complete a revised Definitive Feasibility Study (DFS) with the assistance of Samsung C&T, updating and reviewing the previous development proposal study completed in 2008. Under the MOU, Samsung C&T would provide its technical expertise in engineering, feasibility studies and construction and will use its financial reputation and capacity to assist Metals X with the financing and development proposals for the project.
The objectives of the MOU were for Metals X to retain a 30% interest in the project free carried to production and that Samsung C&T would be awarded the Engineering, Procurement and Construction (EPC) contract for the project on normal and competitive commercial terms. Under the terms of the MOU, Samsung C&T can, depending on the outcomes of the DFS, purchase equity in the project and provide project delivery. SNC-Lavalin was appointed the Principle Engineer for the DFS and was directly awarded the engineering for the Processing and plant infrastructure. Due to the deterioration of the nickel price and the strength of the Australian dollar through 2013, the Board of Metals X reassessed the timing of the DFS and in consultation with Samsung C&T and SNC decided to park up the project until economics improve.
CURRENT STATUS OF WINGELLINA
Whilst the engineering works for the updated feasibility study have been halted, Metals X continues to use its internal resources to complete other long lead-time studies required for the DFS. Metals X has been completing infrastructure, roads, rail and ports studies, and the Public Environmental Review (PER) documentation which is the final documentation required for EPA approval.
As stated in the June quarter the Wingellina environmental scoping study was approved by the EPA on 23 May 2014. Following this approval, the PER document will be formally submitted to the Office of the Environmental Protection Authority by the end of October. This is a significant step in the development of the project as it is the main documentat required for final approvals. The document will undertake the normal review process across WA Government Departments before being released for public review towards the end of the year.
As a result of the successful metallurgical bench testing of the Wingellina ore through an alternative Limonite process that is being developed in Korea, a sample program was completed to obtain a further 100 tonne sample for pilot plant testing in South Korea during the quarter.
Interaction with the State and Federal Governments in relation to infrastructure requirements within central Australia continued with strong co-operation and a desire to assist with the development of the project.
The company entered into an agreement with the Native Title Holders and their representative bodies in 2010 allowing Metals X to develop a mining operation at Wingellina.
WINGELLINA REGIONAL EXPLORATION
Approvals and works have been completed to undertake a drill program to commence at the end of the December quarter to test further Nickel and Cobalt mineralisation in the South Australian tenements and to further define the calcrete deposits used for neutralisation. The program is focused on the known mineralisation located at Scarface with a series of drill lines being undertaken over 4.5 km of strike.
QUARTERLY REPORT 12 FOR THE PERIOD ENDING 30 SEPTEMBER 2014
CORPORATE
During the quarter Metals X was included into the S&P / ASX 300 Index on the commencement of trading on 20 September 2014.
Subsequent to the end of the quarter the Company has announced an inaugural fully frank dividend of 0.6785 cents per share with a record date of 16 December to be paid on 7 January 2015. The company has also announced a Dividend Reinvestment Plan that will attract a 5% discount to the 5 day VWAP prior to reinvestment.
Metals X also announced that it will recommend to shareholders at the AGM on 26 November 2014 that the issued capital of the Company be consolidated on the basis of one (1) new share for every four (4) shares currently on issue. The consolidation will reduce the number of shares on issue from 1,656M to approximately 414M. The Company believes that this will much better align the company with its peers in the market.
During the quarter Metals X entered into a pre-payment arrangement to sell 30,000 ounces of production over 24 months (1,250 oz per month). The net result of this has been to bring forward $40.4M in cashflow at minimal cost.
Metals X ended the September quarter with unaudited cash and working capital of $133.3M. The Group has no corporate debt.

industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fre assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. • Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face- sampling bit or other type, whether core is oriented and if so, by what method, etc). • Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the samples. • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fne/coarse material. |
• Diamond Drilling The bulk of the data used in resource calculations at Trident has been gathered from diamond core. Four types of diamond core sample have been historically collected. The predominant sample method is half-core NQ2 diamond with half-core LTK60 diamond, Whole core LTK48 diamond and whole core BQ also used. This core is logged and sampled to geologically relevant intervals. The bulk of the data used in resource calculations at Chalice has been gathered from diamond core. The predominant drilling and sample type is half core NQ2 diamond. Occasionally whole core has been sampled to streamline the core handling process. Historically half and whole core LTK60 and half core HQ diamond have been used. This core is logged and sampled to geologically relevant intervals. • Face Sampling Each development face / round is chip sampled at both Trident and Chalice. One or two channels are taken per face perpendicular to the mineralisation. The sampling intervals are domained by geological constraints (e.g. rock type, veining and alteration / sulphidation etc.) with an efort made to ensure each 3 kg sample is representative of the interval being extracted. Samples are taken in a range from 0.1 m up to 1.2 m in waste / mullock. All exposures within the orebody are sampled. • Sludge Drilling Sludge drilling at Chalice and Trident is performed with an underground production drill rig. It is an open hole drilling method using water as the fushing medium, with a 64mm or 89mm hole diameter. Samples are taken twice per drill steel (1.9m steel, 0.8m sample). Holes are drilled at sufcient angles to allow fushing of the hole with water following each interval to prevent contamination. • RC Drilling For Fairplay, Vine, Lake Cowan, Two Boys, Mousehollow, Pioneer and Eundynie the bulk of the data used in the resource estimate is sourced from RC drilling. Minor RC drilling is also utilised at Trident, Musket, Chalice and the Palaeochannels (Wills, Pluto, Mitchell 3 & 4). Drill cuttings are extracted from the RC return via cyclone. The underfow from each 1 m interval is transferred via bucket to a four tiered rife splitter, delivering approximately three kilograms of the recovered material into calico bags for analysis. The residual material is retained on the ground near the hole. Samples to wet to be split through the rife splitter are taken asgrabs and are recorded as such. |

| • RAB / Air Core Drilling Drill cuttings are extracted from the RAB and Aircore return via cyclone. 4m Composite samples are obtained by spear sampling from the individual 1m drill return piles; the residue material is retained on the ground near the hole. In the Palaeochannels 1m samples are rife split for analysis. There is no RAB or Aircore drilling used in the estimation of Trident, Chalice, Corona, Fairplay, Vine, Lake Cowan and Two Boys. SKO SKO is a long-term producing operation with a long history of drilling and sampling to support exploration and resource development. • Sampling Techniques Chips from the RC drilling face-sampling hammer are collected for assaying. Sample return lines are cleaned with compressed air each metre and the cyclone sample collector is cleaned following each rod. Samples are rife split through a three-tier splitter with a split ~3kg sample (generally at 1m intervals) pulverised to produce a 30g charge analysed via fre assay. Diamond drill-core is geologically logged and then sampled according to geology (minimum sample length of 0.4 m to maximum sample length of 1.5 m) – where consistent geology is sampled, a 1m length is used for sampling the core. The core is sawn half-core with one half sent of for analysis. Samples have been collected from numerous other styles of drilling at SKO, including but not limited to RAB, aircore, blast-hole, sludge drilling and face samples. • Drilling Techniques Historical data includes DD, RC, RAB and aircore holes drilled between 1984 and 2010. Not all the historical drilling programmes at SKO are documented and many historical holes are assigned a drill type of ‘unknown’. Over 4,000 km of drilling has been completed on the tenure. Drilling by the most recent previous owners (Alacer Gold Corporation) has predominantly been RC, with minor DD and aircore drilling. RC drilling is used predominantly for defning and testing for near-surface mineralisation and utilises a face sampling hammer with the sample being collected on the inside of the drill- tube. RC drillholes utilise downhole single shot camera. Drillhole collars were surveyed by onsite mine surveyors. Diamond drilling is used for either testing / targeting deeper mineralised systems or to defne the orientation of the host geology. Many of these holes had RC pre-collars generally to a depth of between 60 – 120 m, followed by a diamond tail. The majority of these holes have been drilled at NQ2 size with minor HQ sized core. All diamond holes were surveyed during drilling with down hole single shot cameras, and then at end of hole using a Gyro Inclinometer at 5 or 10 m intervals. Drillhole collars were surveyed byonsite mine surveyors. |

| • Sample Recovery Sample recovery is generally good, and there is no indication that sampling presents a material risk for the quality of the evaluation of any deposit at SKO. CMGP • Diamond Drilling A signifcant portion of the data used in resource calculations at the CMGP has been gathered from diamond core. Multiple sizes have been used historically. This core is geologically logged and subsequently halved for sampling. Grade control holes may be whole-cored to streamline the core handling process if required. • Face Sampling At each of the major past underground producers at the CMGP, each development face / round is horizontally chip sampled. The sampling intervals are domained by geological constraints (e.g. rock type, veining and alteration / sulphidation etc.). The majority of exposures within the orebody are sampled. • Sludge Drilling Sludge drilling at the CMGP was performed with an underground production drill rig. It is an open hole drilling method using water as the fushing medium, with a 64mm (nominal) hole diameter. Sample intervals are ostensibly the length of the drill steel. Holes are drilled at sufcient angles to allow fushing of the hole with water following each interval to prevent contamination. Sludge drilling is not used to inform resource models. • RC Drilling RC drilling has been utilised at the CMGP. Drill cuttings are extracted from the RC return via cyclone. The underfow from each interval is transferred via bucket to a four tiered rife splitter, delivering approximately three kilograms of the recovered material into calico bags for analysis. The residual material is retained on the ground near the hole. Composite samples are obtained from the residue material for initial analysis, with the split samples remaining with the individual residual piles until required for re-split analysis or eventual disposal. • RAB / Aircore Drilling Combined scoops from bucket dumps from cyclone for composite. Split samples taken from individual bucket dumps via scoop. RAB holes not included in the resource estimate. • Blast Hole Drilling Cuttings sampled via splitter tray per individual drill rod. Blast holes not included in the resource estimate. • All geology input is logged and validated by the relevant area geologists, incorporated into this is assessment of sample recovery. No defned relationship exists between sample recovery and grade. Nor has sample bias due to preferential loss or gain of fne or coarse material been noted. |

HGO • NQ2 and LTK60 diameter core is sawn half core using a diamond-blade saw, with one half of the core consistently taken for analysis. LTK48 and BQ are whole core sampled. Sludge samples are dried then rife split. • The un-sampled half of diamond core is retained for check sampling if required. • For the onsite Intertek facility the entire dried sample is jaw crushed (JC2500 or Boyd Crusher) to a nominal 85% passing 2 mm with crushing equipment cleaned between samples. An analytical sub-sample of approximately 500-750 g is split out from the crushed sample using a rife splitter, with the coarse residue being retained for any verifcation analysis. Sample preparation techniques are appropriate for the type of analytical process. • Where Fire assay has been used the entire half core sample (3-3.5 kg) is crushed and pulverised (single stage mix and grind using LM5 mills) to a target of 85-90% passing 75μm in size. A 200g sub-sample is then separated out for analysis • Core and underground face samples are taken to geologically relevant boundaries to ensure each sample is representative of a geological domain. Sludge samples are taken to nominal sample lengths. • The sample size is considered appropriate for the grain size of the material being sampled. • For RC, RAB and Aircore chips regular feld duplicates are collected and analysed for signifcant variance to primary results. • RAB and Aircore sub-samples are collected through spear sampling. |

The un-sampled half of diamond core is retained for check sampling if required. SKO staf collect the sample in pre-numbered calico sample bags which are then submitted to the laboratory for analysis. Delivery of the sample is by an SKO staf member and as such. • RC samples are collected at 1m intervals with the samples being rife split through a three- tier splitter. The samples are collected by the RC drill crews in pre-numbered calico sample bags which are then collected by SKO staf for submission. Delivery of the sample to the laboratory is by an SKO staf member. • Upon delivery to the laboratory, the sample numbers are checked by the SKO staf member against the sample submission sheet. Sample numbers are recorded and tracked by the laboratory using electronic coding. • Sample preparation techniques are considered appropriate for the style of mineralisation being tested for – this technique is industry standard across the Eastern Goldfelds.

| Quality of assay data and laboratory tests |
• The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. • Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. |
HGO • At the Intertek on-site facility, analysis is performed using a 500g PAL method. The accurately weighed sub-sample is further processed utilising a PAL1000B to grind the sample to a nominal 90% passing 75µm particle size, whilst simultaneously extracting any cyanide amenable gold liberated into a Leachwell liquor. The resulting liquor is then analysed for gold content by organic extraction with fame AAS fnish, with an overall method detection limit of 0.01ppm Au content in the original sample. This method is appropriate for the type and magnitude of mineralisation at Higginsville. • Quality control procedures include the use of standards, blanks and duplicates. Standards and duplicates are used to test both the accuracy and precision of the analytical process, while blanks are employed to test for contamination during the sample preparation stage. The analyses have confrmed the analytical process employed at Higginsville is adequately precise and accurate for use as part of the mineral resource estimation. SKO • Only nationally accredited laboratories are used for the analysis of the samples collected at SKO. • The laboratory dry and if necessary (if the sample is >3kg) rife split the sample, which is then jaw crushed and pulverised (the entire 3kg sample) in a ring mill to a nominal 90% passing 75 microns. All recent RC and Diamond core samples are analysed via Fire Assay, which involves a 30g charge (sub-sampled after the pulverisation) of the analytical pulp being fused at 1050°C for 45 minutes with litharge. The resultant metal pill is digested in aqua regia and the gold content determined by atomic adsorption spectrometry – detection limit is 0.01 ppm Au. • Quality Assurance and Quality Control (QA/QC) samples are routinely submitted by SKO staf and comprise standards, blanks, assay pills, feld duplicates, lab duplicates and repeat analyses. The results for these QA/QC samples are routinely analysed by Senior Geologists with any discrepancies dealt with in conjunction with the laboratory prior to the analytical data being imported into the database. • There is limited information available on historic QA/QC procedures. SKO has generally accepted the available data at face value and carry out data validation procedures as each deposit is re-evaluated. • The analytical techniques used are considered appropriate for the style of mineralisation being tested for – this technique is industry standard across the Eastern Goldfelds. • Ongoing production data generally confrms the validity of prior sampling and assaying of the mined deposits to within acceptable limits of accuracy. |

| Verifcation of sampling and assaying |
• The verifcation of signifcant intersections by either independent or alternative company personnel. • The use of twinned holes. • Documentation of primary data, data entry procedures, data verifcation, data storage (physical and electronic) protocols. • Discuss any adjustment to assay data. |
• No independent or alternative verifcations are available. • Virtual twinned holes have been drilled in several instances across all sites with no signifcant issues highlighted. Drillhole data is also routinely confrmed by development assay data in the operating environment. • Primary data is collected on paper or on tough book using a standard excel template. The information is imported into a SQL database server and verifed. • All data used in the calculation of resources and reserves are compiled in databases (underground and open pit) which are overseen and validated by senior geologists. • No adjustments have been made to anyassaydata. |
| Location of data points | • Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. • Specifcation of the grid system used. • Quality and adequacy of topographic control. |
HGO • Collar coordinates for surface drill-holes were generally determined by GPS, with underground drill-holes generally determined by survey pick-up. Downhole survey measurements for most surface diamond holes were by Gyro-compass at 5m intervals. Holes not gyro-surveyed were surveyed using Eastman single shot cameras at 20m intervals. Downhole surveys for underground diamond drill-holes were taken at 15 – 30m intervals by Refex single-shot cameras. Routine survey pick-ups of underground and surface holes where they intersected development indicates (apart from some minor discrepancies with pre-Avoca drilling) a survey accuracy of less than 5m. • All drilling and resource estimation is undertaken in local mine grid at the various projects. • Topographic control is generated from Diferential GPS. This methodology is adequate for the resource inquestion. |

| SKO • Collar coordinates for surface RC and diamond drill-holes were generally determined by either RTK-GPS or a total station survey instrument. Underground drill-hole locations (Mount Marion and HBJ) were all surveyed using a Leica refectorless total station. • Recent surface diamond holes were surveyed during drilling with down-hole single shot cameras and then at the end of the hole by Gyro-Inclinometer at 5 or 10mm intervals. Holes not gyro-surveyed were surveyed using Eastman single shot cameras at 20m intervals. RC drill-holes utilised down-hole single shot camera surveys spaced every 15 to 30m down-hole. • Down-hole surveys for underground diamond drill-holes were taken at 15 – 30m intervals by Refex single-shot cameras. • The orientation and size of the project determines if the resource estimate is undertaken in local or MGA 94 grid. Each project has a robust conversion between local, magnetic and an MGA grid which is managed by the SKO survey department. • Topographic control is generated from RTK GPS. This methodology is adequate for the resources in question. CMGP • All data is spatially oriented by survey controls via direct pickups by the survey department. Drillholes are all surveyed downhole, deeper holes with a Gyro tool if required, the majority with single / multishot cameras. • All drilling and resource estimation is undertaken in local mine grid at the various sites. • Topographic control is generated from a combination of remote sensing methods and ground- based surveys. This methodologyis adequate for the resource inquestion. |

| Data spacing and distribution | • Data spacing for reporting of Exploration Results. • Whether the data spacing and distribution is sufcient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifcations applied. • Whether sample compositing has been applied. |
HGO • Drilling in the underground environment at Chalice and Trident is nominally carried-out on 20m x 30m spacing for resource defnition and in flled to a 10m x 15m spacing with grade control drilling. At trident the drill spacing below the 500RL widens to an average of 40m x 80m. At Chalice below the 880RL the typical drill spacing 60m x 60m. Mining has shown that this data spacing is appropriate for the Mineral Resource estimation process and to allow for classifcation of the resource as it stands. • Drilling at the Lake Cowan region is on a 20m x 10m spacing. Historical mining has shown this to be an appropriate spacing for the style of mineralisation and the classifcations applied. • Compositing is carried out based upon the modal sample length of each project. |

| SKO HBJ: Drill spacing ranges from 10m x 5m grade control drilling to 100m x 100m at deeper levels of the resource. The majority of the Indicated Resource is estimated using a maximum drill spacing of 40m x 40m. The resource has been classifed based on drill density with mining of the 2.2km long HBJ Open-Pit confrming that the data spacing is adequate for the resource classifcations applied. Mount Martin: Drill spacing ranges from 10m x 5m grade control drilling to 60m x 60m for the Inferred areas of the resource. The drill spacing for the majority of the Indicated Resource is 20m x 20m. The resource has been classifed primarily on drill density and the confdence in the geological/ grade continuity – the data spacing and distribution is deemed adequate for the estimation techniques and classifcations applied. Pernatty: Drill spacing for the reported resource is no greater than 60m x 60m with the majority of the Indicated resource based on a maximum spacing of 40m x 40m. The geological interpretation of the area is well understood, and is supported by the knowledge from open pit and underground operations. However given the mineralisation is controlled by shear zones the mineralisation continuity is considered to be less understood. The resource is classifed on a combination of drill density and the number of samples used to estimate the resource blocks. Mount Marion: Drill-spacing ranges from 20m x 20m to no greater than 60m x 60m for the reported resource Given that the geological and mineralisation understanding is well established via mining operations, this drill-spacing is considered adequate for the classifcations applied to the resource. Compositing is carried out based upon the modal sample length of each project. CMGP • Data spacing is variable dependent upon the individual orebody under consideration. A lengthy history of mining has shown that this approach is appropriate for the Mineral Resource estimation process and to allow for classifcation of the resource as it stands. Compositingis carried out based upon the modal sample length of each individual domain. |

• Acknowledgment and appraisal of exploration by other partie • Deposit type, geological setting and style of mineralisation. |
• The Higginsville region has an exploration and production history in excess of 30 years. • The SKO tenements have an exploration and production history in excess of 40 years. • Metals X / Alacer work has generally confrmed the veracity of historic exploration data. HGO • Trident is hosted primarily within a thick, weakly diferentiated gabbro with subordinate mafc and ultramafc lithologies and comprises a series of north-northeast trending, shallowly north-plunging mineralised zones. The deposit comprises two main mineralisation styles; large wallrock-hosted ore-zones comprising sigmoidal quartz tensional vein arrays and associated metasomatic wall rock alteration hosted exclusively within the gabbro; and thin, lode-style, nuggety laminated quartz veins that formed primarily at sheared lithological contacts between the various mafc and ultramafc lithologies. • Chalice geology is characterised by NNW-striking and W-dipping intercalated mafc and ultramafc volcanic rocks that are metamorphosed to mid-amphibolite facies. This sequence is bounded to the west and east by thick granitic bodies of the Boorabin Batholith and Pioneer Dome Batholith respectively. The dominant unit that hosts gold mineralisation is a fne grained, weakly to strongly foliated amphibole-plagioclase amphibolite. Two major, and one minor, ultramafc units occur as discontinuous members throughout the deposit. Four generations of granitic dike intrude the lithostratigraphic sequence. The mineralisation is characterised by strong diopside-hornblende-albite alteration with associated pyrite / pyrrhotite sulphides. Mineralisation occurs with highly foliated and folded host rock with width varying up to 50m. • Lake Cowan mineralisation can be separated into two types. Structurally controlled primary mineralisation in ultramafcs, basalts and felsics host (e.g. Louis, Josephine and Napoleon), and saprolite / palaeochannel hosted supergene hydromorphic deposits, including Sophia, Brigitte and Atreides. |

SKO HBJ: The HBJ lodes form part of a gold mineralised system along the Boulder-Lefroy shear zone that is over 5km long and includes the Celebration, Mutoroo, HBJ and Golden Hope open-pit and underground mines. The lodes are hosted within a steeply-dipping, north-northwest striking package of mafic, ultramafic and sedimentary rocks and schists that have been intruded by felsic to intermediate porphyries. Gold mineralisation is structurally controlled and is focused along lithological contacts, within stockwork and tensional vein arrays and within shear zones. The main mineralised zone has a length in excess of 1.9 km and an average width of 40 m in the Jubilee workings but is generally narrower to the north in the Hampton-Boulder workings. Mount Marion: The Mount Marion deposit is located on the eastern side of the Coolgardie Domain within a flexure in the Karramindie Shear Zone. It is hosted within a sub-vertical sequence of metakomatiites intercalated with metasediments that have been metamorphosed to amphibolite facies. Gold mineralisation occurs in a footwall and hangingwall lode, each ranging in thickness from 2 to 15m. The mineralisation plunges steeply to the west and is open at depth. Mount Martin: The Mount Martin Tribute Area, is located within a regional scale north-northwest trending Archaen Greenstone Belt. Within the Mount Martin – Carnilya area, the greenstone belt comprises a mixed sequence of ultramafic (predominantly komatiitic) and fine-grained, variably sulphidic sedimentary lithologies with subsidiary mafic units. Known gold and nickel mineralisation at the Mount Martin Mine is associated with a series of stacked, westerly dipping, sulphide and quartz-carbonate bearing lodes which are mainly hosted within intensely deformed and altered chloritic schists sandwiched between talc-carbonate ultramafic lithologies. Pernatty: The Pernatty deposit is hosted within a granophyric phase of a gabbro and is controlled by a structurally complex interaction of a number of major shear zones. Shearing has altered the original granophyric quartz dolerite to a biotite-carbonate-plagioclase-pyrite schist. The sequence has also been intruded by mafic and felsic porphyritic dykes, which are also mineralised.

| CMGP • The CMGP is located in the Achaean Murchison Province, a granite-greenstone terrane in the northwest of the Yilgarn Craton. Greenstone belts trending north-northeast are separated by granite-gneiss domes, with smaller granite plutons also present within or on the margins of the belts. • Mineralisation at Big Bell is hosted in the shear zone (Mine Sequence) and is associated with the post-peak metamorphic retrograde assemblages. Stibnite, native antimony and trace arsenopyrite are disseminated through the K-feldspar-rich lode schist. These are intergrown with pyrite and pyrrhotite and chalcopyrite. Mineralisation outside the typical Big Bell host rocks (KPSH), for example 1,600N and Shocker, also display a very strong W-As-Sb geochemical halo. • Numerous gold deposits occur within the Cuddingwarra Project area, the majority of which are hosted within the central mafc-ultramafc ± felsic porphyry sequence. Within this broad framework, mineralisation is shown to be spatially controlled by competency contrasts across, and fexures along, layer-parallel D2 shear zones, and is maximised when transected by corridors of northeast striking D3 faults and fractures. • The Great Fingall Dolerite hosts the majority gold mineralisation within the portion of the greenstone belt proximal to Cue (The Day Dawn Project Area). Unit AGF3 is the most brittle of all the fve units and this characteristic is responsible for its role as the most favourable lithological host togold mineralisation in the Greenstone Belt. |

HGO • Current and historical mining activities across the Higginsville region provide signifcant confdence in the geological interpretation of all projects. • No alternative interpretations are currently considered viable. • In all cases the local lithological and structural geology has been used to inform the interpretive process. All available information from drilling, underground mapping and pit mapping has been considered during interpretation. • The Trident, Corona, Fairplay, Vine and Two boys deposits are all hosted within a suite of east over west thrust repeated mafc, ultramafc and sedimentary rocks. In all cases the most favourable host is of mafc composition, generally gabbro and to a lesser extent basalt. Together the deposits form what is locally referred to as the Higginsville Line of Lode, a 5km long, north-northeast striking mineralised corridor of historic and current mining operations. Steep west and shallow east have been identifed as the most favourable structural orientations for mineralisation. • At Chalice, multiple generations of unmineralised felsic intrusive cross cut the host amphibolite and infuence both the volume and the grade, through contact remobilisation, of the mineralisation. The Resource Estimate is sensitive to the volume of unmineralised felsics within the mineralised horizon. • At both Chalice and Lake Cowan there is a lack of consistent visual proxies for mineralisation, making accurate ore delineation difcult. • High-grade zones within the palaeochannels are the result of a more preferential depositional environment due to changes in strike of thepalaeochannel. |

SKO HBJ: The mineralisation has been modelled focussing on the structural (shear zone) and lithological (porphyry mainly) controls. The large scale (1.9km long and ~40m wide) provides significant confidence in the geological and grade continuity within the deposit. The interpretation has used predominantly RC drilling with some DD used for the deeper parts of the resource. There is an alternative interpretation that could be applied to this deposit, which focuses on defining and sub-domaining higher grade mineralisation that is evident at lithological contacts. Mount Marion: The lithological and structural model for the Mount Marion deposit is well understood as it is supported by the knowledge gained from open-pit and underground operations. The mineralisation is hosted along a dilational flexure within the lode gneiss with clearly defined contact mineralisation with the surrounding ultramafic lithologies. The lithological model is used as the basis for the mineralisation interpretation and has been derived from predominantly RC and Diamond drill-holes. The confidence of the geological controls on mineralisation is consistent with the resource classification applied to the deposit. No alternative interpretations have been devised for this deposit. Mount Martin: Gold mineralisation at Mount Martin is associated with chlorite schists (shear zones) hosted within talc-carbonate ultramafic lithologies. Within these controlling shear zones are a series of stacked, westerly-dipping, sulphide and quartz carbonate bearing lodes which host the majority of the gold mineralisation. The geological and mineralisation interpretation used in this resource is consistent with that mined historically in the open pit. Although other interpretations have been proposed they tend to be variations on the steep westerly-dipping lodes theme adopted for this resource and as such would not represent a significant change in the contained metal. Pernatty: Mineralisation at Pernatty is controlled by a complex arrangement of very well-defined shear zones with the highest grade mineralisation associated with structural intersections and flexures along the three main shears. Given the consistency in orientation of the three main controlling shears, the confidence in the geological and mineralisation interpretation is deemed adequate.

| CMGP Mining has occurred since 1800’s providing signifcant confdence in the currently geological interpretation across all projects. No alternative interpretations are currently considered viable. Geological interpretation of the deposit was carried out using a systematic approach to ensure that the resultant estimated Mineral Resource fgure was both sufciently constrained, and representative of the expected sub-surface conditions. In all aspects of resource estimation the factual and interpreted geology was used to guide the development of the interpretation. The structural regime is the dominant control on geological and grade continuity at the CMGP. Lithological factors such as rheologycontrast are secondarycontrols ongrade distribution. |

HGO • The Trident mineral resource extends over 680m in strike length, 350m in lateral extent and 940m in depth. • Chalice mineralisation has been defned over a strike length of 700m, a lateral extent of 200m and a depth of 650m. • The Lake Cowan resource has been defned over a strike length of >1.5Km, a lateral extent of >500m and to a depth of >150m. • SKO • The HBJ deposit extends over 5km of strike (includes the Golden Hope and Mutooroo lodes) and up to 650m below surface with the individual lodes being up to 40m wide. • Mount Marion mineralisation extends to just under 1km in strike length, 800m in depth with the lodes varying in width from 3 – 15m. The mineralisation is steeply plunging resulting in a very small surface expression of the lodes. • The Mount Martin deposit has a strike length of 1km, a vertical extent of 350m, with the individual, shallow west-southwesterly dipping lodes varying between 2 – 10m true thickness. These lodes make up a mineralised package of ~300m true thickness (hangingwall to footwall). • The Pernatty desposit has a strike extent of 500m, 400m dip extent and up to 300m in lateral extent. The individual lodes are of varying orientations and are generally between 2 – 15m wide. CMGP • Individual deposit scales vary across the CMGP. • The Big Bell Trend is mineralised a strike length of >3,900m, a lateral extent of up +50m and a depth of over 1,500m. • Great Fingall is mineralised a strike length of >500m, a lateral extent of >600m and a depth of over 800m. • Black Swan South is mineralised a strike length of >1,700m, a lateral extent of up +75m and a depth of over 300m. |

• The nature and appropriateness of the estimation technique(s) applied and key assumptions, including treatment of extreme grade values, domaining, interpolation parameters and maximum distance of extrapolation from data points. If a computer assisted estimation method was chosen include a description of computer software and parameters used. • The availability of check estimates, previous estimates and/or mine production records and whether the Mineral Resource estimate takes appropriate account of such data. • The assumptions made regarding recovery of by-products. • Estimation of deleterious elements or other non-grade variables of economic signifcance (eg sulphur for acid mine drainage characterisation). • In the case of block model interpolation, the block size in relation to the average sample spacing and the search employed. • Any assumptions behind modelling of selective mining units. • Any assumptions about correlation between variables. • Description of how the geological interpretation was used to control the resource estimates. • Discussion of basis for using or not using grade cutting or capping. • The process of validation, the checking process used, the comparison of model data to drill hole data, and use of reconciliation data if available. |
• HGO • For Trident, Chalice, Two Boys, Vine and Lake Cowan the modelling and estimation work was undertaken by Alacer Gold and carried out in Vulcan 3D mining software. • For Alacer Gold estimates the drill hole data to be used in the process is frst validated. The initial interpretation is then completed on 1:250 scale hardcopy cross sections, long sections and level plans, this interpretation is then validated by either the senior geologists or the Chief Geologist before then being digitised into the Vulcan 3D modelling package. The digitised polygons form the basis of the three dimensional orebody wireframe. Wireframing is then carried out using a combination of automated stitching algorithms and manual triangulation to create an accurate three dimensional representation of the sub-surface mineralised body. • Drillhole intersections within the mineralised body are defned, these intersections are then used to fag the appropriate sections of the drillhole database tables for compositing purposes. Drillholes are subsequently composited to allow for grade estimation. In all aspects of resource estimation the factual and interpreted geology was used to guide the development of the interpretation. • Once the sample data has been composited, a statistical analysis is undertaken to assist with determining estimation search parameters, top-cuts etc, this is carried out using Supervisor. Top cut analysis was carried out by assessing normal and log-histograms for extreme values and using a combination of mean variance plots and population disintegration techniques. Variographic analysis of individual domains is undertaken to assist with determining appropriate search parameters. In all cases knowledge of the geology was used to guide the analysis of the variogram fans in determining the orientation of maximum continuity. • An empty block model is then created for the area of interest; with each ore wireframe used to assign block domain codes which match the fag used for the composites. This model contains attributes set at background values for gold as well as density, and various estimation parameters that are subsequently used to assist in resource categorisation. The block sizes used in the model will vary depending on orebody geometry, minimum mining units, estimation parameters and levels of informing data available. • Grade estimation is then undertaken, with ordinary kriging estimation as standard, although in some circumstances where sample populations are small, or domains are unable to be accurately defned, inverse distance weighting estimation techniques will be used. At Trident a grade assignment method has been employed for the Athena orebody. This uses face sampling/mapping on each level to identify runs of vein with similar width and grade profles. For each run, the length of the run and average vein width is calculated as well as a width weighted average vein grade. Two or more grade runs are then joined up across levels to form a grade block, a long section is used to validate the plunge of each grade block against the diamond drilling. The length and width of each run is used to calculate a length weighted average grade and an average vein width for the block. A wireframe for each grade block is created at the specifed average vein width for the block. This wireframe is then assigned the previously calculated block grade using a post process script. • No by-products or deleterious elements are estimated. • No assumptions have been made about the correlation between variables. |

| • The estimation is validated using the following: a visual interrogation, a comparison of the mean composite grade to the mean block grade for each domain, a comparison of the wireframe volume to the block volume for each domain, Grade trend plots (moving window statistics), comparison to the previous resource estimate. • The resource is then depleted for mining voids and subsequently classifed in line with JORC guidelines utilising a combination of various estimation derived parameters and geological / mining knowledge. • Production reconciliation data is regularly used to check the performance of the estimate and to adjust parameters is necessary. • Good reconciliation between mine claimed fgures and milled fgures is routinelyachieved. |

| SKO • The HBJ mineral resource estimate was undertaken in December 2011 by Widenbar and Associates Pty Ltd. The grade interpolation method used was Ordinary Kriging (OK) in the Datamine ESTIMA process – a method that is appropriate for the style of mineralisation being estimated. A simple unfolding process has been applied to the data and model blocks in order to simplify the setup of search ellipses and allow searches to follow the varying dip and strike of the various domains. • Geological, mining as-built and mineralisation domains and a valid drillhole database were supplied by SKO personnel. The geological and mineralisation domains were used to control the interpolation as hard boundaries (mineralisation domains) and for the application of bulk density data (geological boundaries). • The Mineral Resource estimates for Mount Marion, Mount Martin and Pernatty were undertaken by Alacer Gold in September 2011. The geological and mineralisation wireframes as well as the grade interpolation was undertaken in Vulcan 8.04 3-D modelling software with statistical analysis undertaken using Snowden Supervisor software. The interpolation method used was Ordinary Kriging (OK) – a method that is appropriate for the styles of mineralisation being estimated. • Statistical analysis was undertaken to determine the composite length (1m) and for the application of top-cuts. • The search ellipses applied were based on a combination of drillhole spacing and variographic analysis. Various minimum and maximum samples were used in the frst search with a maximum of four samples per drill-hole allowed. Several passes were used each with increasing search ellipse sizes, all the blocks in the mineralised domains were informed in the frst pass. • The block model was depleted using surfaces / domains generated by the SKO Survey. • Validation of the models was completed by visual inspection, statistical comparisons and comparison with reconciliation data, with the fnal model achieving a satisfactory validation. • No deleterious elements were estimated as theyare considered not material. |

| Bulk density | • Whether assumed or determined. If assumed, the basis for the assumptions. If determined, the method used, whether wet or dry, the frequency of the measurements, the nature, size and representativeness of the samples. • The bulk density for bulk material must have been measured by methods that adequately account for void spaces (vugs, porosity, etc), moisture and diferences between rock and alteration zones within the deposit. • Discuss assumptions for bulk density estimates used in the evaluation process of the diferent materials. |
HGO • For both Trident and Chalice bulk densities were assessed via test work and assigned to the model. Samples were selected to cover the full range of lithology types and ore types across the deposit. Individual unbroken half core samples of approximately 30cm length were randomly selected from within specifed metre intervals. Samples were sent to the Genalysis Laboratory in Kalgoorlie, where mass and volumes (by water immersion) were measured and bulk density calculated. • Where no drill core or other direct measurements are available, SG factors have been assumed based on similarities to other zones of mineralisation / lithologies or from historic production records. SKO • For the HBJ, Mount Marion, Pernatty and Mount Martin deposits, density values were based on historic mining reconciliations combined with bulk density check test work. • Bulk densities were assigned based on the host rock, mineralisation style and oxidation state, all of which were coded into the block models. CMGP • Bulk density of the mineralisation at the CMGP is variable and is for the most part lithology rather than mineralisation dependent. Bulk density sampling is undertaken via assessments of drill core and grab samples. • A signifcant past mining history has validated the assumptions made surrounding bulk densityat the CMGP. |
| Classifcation | • The basis for the classifcation of the Mineral Resources into varying confdence categories. • Whether appropriate account has been taken of all relevant factors (ie relative confdence in tonnage/grade estimations, reliability of input data, confdence in continuity of geology and metal values, quality, quantity and distribution of the data). • Whether the result appropriatelyrefects the Competent Person’s view of the deposit. |
• Resources are classifed in line with JORC guidelines utilising a combination of various estimation derived parameters, input data and geological / mining knowledge. • This approach considers all relevant factors and refects the Competent Person’s view of the deposit |
| Audits or reviews | • The results of any audits or reviews of Mineral Resource estimates. |
• Resource estimates are peer reviewed by the site technical team. • No external reviews have been undertaken. |
| Discussion of relative accuracy/ confdence |
• Where appropriate a statement of the relative accuracy and confdence level in the Mineral Resource 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 resource within stated confdence limits, or, if such an approach is not deemed appropriate, a qualitative discussion of the factors that could afect the relative accuracy and confdence 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. • These statements of relative accuracy and confdence of the estimate should be compared withproduction data, where available. |
• All currently reported resources estimates are considered robust, and representative on both a global and local scale. • A continuing history of mining with good reconciliation of mine claimed to mill recovered provides confdence in the accuracy of the estimates. |

HGO • Mining is in progress at both Chalice and Trident. • The Chalice underground mine has been in operation since 2011, with historical open pit and underground workings having been established in the 1990’s by Resolute Mining. The mining methodology, design layouts, production performance, mining modifying factors and cost profles used in the 2014 Mineral Reserve are therefore refective of this history. • The Trident Underground mine began production in late 2008. The mining methodology, design layouts, production performance, mining modifying factors and cost profles used in the 2014 Mineral Reserve are therefore refective of this history. • Underground mining costs have been derived from the current Australian Contract Mining (ACM) rates. • The Lake Cowan Mining Centre (including Louis Pit) was mined in the 2000’s by Harmony Gold. The Reserve for Louis involves depth and width extension of the current Pit. • Following exploration and infll drilling activity, annual resource updates and economic assessment of the Measured and Indicated resources is completed using actual costs, operating parameters and modifying factors. An annual update of Ore Reserves is completed on this basis. SKO • Economic assessment of the stockpiles is undertaken regularly using actual costs of processing inclusive of administration at SKO. CMGP • A comprehensive Defnitive Feasibility Study utilising a combination of internal and external expertise has been undertaken to allow the conversion of Mineral Resources to Ore Reserves. |

• Underground Mines - Cut of grades were determined for the various mining methods and |
| various mining sections in the mine. The COG’s have been applied to both development and stope production from their respective areas. • Open Pit Mines - The pit rim cut of grade (COG) was determined as part of the Reserve estimation. The pit rim COG determines which material will be processed by equating the operating cost of processing and selling to the value of the mining block in terms of recovered metal and the expected selling price. The COG is then used to determine whether or not a mining block should be delivered to the treatment plant for processing or taken to the waste dumpas waste. |

| Mining factors or assumptions | • The method and assumptions used as reported in the Pre-Feasibility or Feasibility Study to convert the Mineral Resource to an Ore Reserve (i.e. either by application of appropriate factors by optimisation or by preliminary or detailed design). • The choice, nature and appropriateness of the selected mining method(s) and other mining parameters including associated design issues such as pre-strip, access, etc. • The assumptions made regarding geotechnical parameters (eg pit slopes, stope sizes, etc), grade control and pre-production drilling. • The major assumptions made and Mineral Resource model used for pit and stope optimisation (if appropriate). • The mining dilution factors used. • The mining recovery factors used. • Any minimum mining widths used. • The manner in which Inferred Mineral Resources are utilised in mining studies and the sensitivity of the outcome to their inclusion. • The infrastructure requirements of the selected mining methods. |
• Ore Reserves have been undertaken on a ‘bottom up’ process – with the physicals refecting mine designs rather than Resource conversion factors or Whittle optimisations. HGO • Mining methodologies for underground Reserves centre on long hole open stoping. However, there are areas which are designed as narrow vein up hole or fat bench stoping. All methods described in the Reserve have either been trialled successfully and/or implemented historically. The stope design parameters take into account the diferent mining shapes and are based on specifc geology and geotechnical domains associated with those areas. Stope shapes, level layouts and extraction sequences are designed cognisant of local and regional ground conditions. Where deteriorating ground conditions are expected or where signifcant fault planes run adjacent to mineralisation, stope shapes are altered to encompass these conditions and sequenced early to ensure recovery is possible. • Dilution factors vary pending the orebody style and host rock conditions as well as from mining sequence and development layouts. • Each mining method applied has a minimum width, which corresponds to sub level distances, blast hole drill accuracy constraints, nature of the mineralisation and/or feet fexibility. • With the implementation of paste flling at Trident and the utilisation of remote loaders with telecabins, a 100% mining recovery factor is applied to the stope physicals. • No Inferred resources are included with the Reserve Statement. • Both underground mines are established production centres and have been in operation for several years. Mining methodologies forecasted in the Reserve are those currently being utilised. • Conventional open pit mining methodologies and sequencing have been applied to open pits. • A 6% dilution factor has been applied to Louis Reserve. • Louis has a 95% mining recovery factor. • Wall angles used in the Louis Pit are refective of the historical parameters used. • Lake Cowan has pre-existing haulage routes and site earthworks. Re-establishment of the haulage route into Higginsville has been costed as is included within the economic analysis. SKO • As all SKO reserves are stockpile no mining factors or assumptions are applied during assessment of their viability. |

• The metallurgical process proposed and the appropriateness of that process to the style of mineralisation. • Whether the metallurgical process is well-tested technology or novel in nature. • The nature, amount and representativeness of metallurgical test work undertaken, the nature of the metallurgical domaining applied and the corresponding metallurgical recovery factors applied. • Any assumptions or allowances made for deleterious elements. • The existence of any bulk sample or pilot scale test work and the degree to which such samples are considered representative of the orebody as a whole. • For minerals that are defned by a specifcation, has the ore reserve estimation been based on the appropriate mineralogy to meet the specifcations? |
HGO • Gold extraction is achieved using staged crushing, ball milling with gravity concentration and Carbon in Leach. The Higginsville plant has operated since 2008 and historical recoveries on Trident ore average 97% and Chalice 95%. • Treatment of ore is via conventional gravity recovery / intensive cyanidation and CIL is applied as industry standard technology. • Host mineralisation has been consistent within the Trident and Chalice orebodies, and historical high gold extractions achieved at full commercial production rates. Additional testwork is instigated where notable changes to geology and mineralogy are identifed. Small scale batch leach tests on primary Louis ore have indicated lower recoveries (80%) associated with fner gold and sulphide mineralisation. • There have been no major examples of deleterious elements afecting gold extraction levels or bullion quality. Some minor variations in sulphide mineralogy have had short term impacts on reagent consumptions. • No bulk sample testing is required whilst geology/mineralogy is consistent based on treatment plant performance. SKO • All SKO stockpiles have a signifcant processing history and metallurgical performance is well understood. • A long history of processing through the existing facility demonstrates the appropriateness of the process to the styles of mineralisation considered. • No deleterious elements are considered, as a long history of processing has shown this to be not a material concern. |

• Diamond Drilling - Half-core niche samples, sub-set via geological features as appropriate. • Core undergoes total preparation. • The sample preparation process consists of: » Crushing using a vibrating jaw crusher to achieve a maximum sample size of 4mm. » The sample is then weighed, and if the sample weight is greater than 3.2kg, the sample is split into two using a Jones-type Rife splitter. » The crushed sample is then pulverised in a Labtech LM5 Ring Mill for 6 minutes. For samples weighing greater than 3.2kg the frst portion is removed and second portion is homogenised in the same machine. Once complete the frst portion is put back in the LM5 and both portions are homogenised. » From the pulverised sample, approximately 200g is taken as a master sample which stays in Alice Springs, while a second sample of approximately 150g taken and sent to for assaying. These samples are collected via a scoop inserted to the bottom of the bowl. The remaining sample is transferred to a calico bag for storage. » For every 20th sample, an approximately 25g sample is screened to 75 microns to check that homogenising has achieved 80% passing 75 microns. • QA/QC is ensured during sampling via the use of sample ledgers, blanks, standards and repeats. • QA/QC is ensured during the assays process via the use of blanks, standards and repeats at a NATA / ISO accredited laboratory. • The sample sizes are considered appropriate to the grainsize of the material being sampled. • The un-sampled half of diamond core is retained for check samplingif required. |

• The Tennant Creek Project comprises 5 granted exploration leases. • Native title interests are recorded against the Tennant Creek tenements. • The Tennant Creek tenements are held by Castile with is 100% Metals X owned. • Several third party royalties exist across various tenements at Tennant Creek, over and above the Northern Territory government royalty. • Castile operates in accordance with all environmental conditions set down as conditions for grant of the leases. • There are no known issues regarding security of tenure. • There are no known impediments to continued operation. • The Tennant Creek area has an exploration and production history in excess of 100 years. The Rover area in particular has an intensive exploration history stretching from the 1970’s. • On balance, Castile work has generally confrmed the veracity of historic exploration data. • The Tennant Creek Project is located in the 1860-1850Ma Warramunga Province is approximately centred on the township of Tennant Creek, and contains the Palaeoproterozoic Warramunga Formation. This is a weakly metamorphosed turbiditic succession of partly tufaceous sandstones and siltstones which includes argillaceous banded ironstones locally referred to as ‘haematite shale’. • Copper in the form of chalcopyrite occurs around the upper margins of the quartz magnetite ironstones and in the silicifed BIF or haematitic shales that often form an alteration transition to the adjacent chlorite alteration envelope. Although copper levels in the upper quartz magnetite portion of the ironstones is usually very low, pervasive sub-economic copper levels can persist throughout this zone. Economic levels of copper are dominantly contained in the lower massive magnetite portion or in massive magnetite “veins” identifed in the magnetite quartz zones. The massive magnetite zones grade laterally and at depth into magnetite chlorite stringer zones. Gold content increases where the content of magnetite veining and chlorite alteration decreases and there is an increase in early haematite dusted quartz veins and indurated sediments and fne chlorite veining related to the mineralisation phase. The transition from massive magnetite copper mineralisation to magnetite quartz chlorite stringer gold mineralisation is also the zone of increased bismuthinite mineralisation. • Lead and zinc mineralisation at Explorer 108 is associated with a brecciated dolomitised sediment unit, consisting of irregular, generally narrow, domains or veins of semi-massive sulphides (sphalerite and galena). A basal “high-grade” zone is present at the contact of the dolomite and lower felsic units. |

| Database integrity | • Measures taken to ensure that data has not been corrupted by, for example, transcription or keying errors, between its initial collection and its use for Mineral Resource estimation purposes. • Data validation procedures used. |
• Drillhole data is stored in a Maxwell’s DataShed system based on the Sequel Server platform which is currently considered “industry standard”. • As new data is acquired it passes through a validation approval system designed to pick up any signifcant errors before the information is loaded into the master database. The information is uploaded by a series of Sequel routines and is performed as required. The database contains diamond drilling (including geotechnical and specifc gravity data), face chip and sludge drilling data and some associated metadata. By its nature this database is large in size, and therefore exports from the main database are undertaken (with or without the application of spatial and various other flters) to create a database of workable size, preserve a snapshot of the database at the time of orebody modelling and interpretation and preserve the integrityof the master database. |

• Mining of similar deposits in the region provides confdence in the current geological interpretation. • No alternative interpretations are currently considered viable. • Geological interpretation of the deposit was carried out using a systematic approach to ensure that the resultant estimated Mineral Resource fgure was both sufciently constrained, and representative of the expected sub-surface conditions. In all aspects of resource estimation the factual and interpreted geology was used to guide the development of the interpretation. • The structural regime and the presence of intrusive source bodies are the dominant controls ongeological andgrade continuityat the Tennant Creek Project. |

| Estimation and modelling techniques |
• The nature and appropriateness of the estimation technique(s) applied and key assumptions, including treatment of extreme grade values, domaining, interpolation parameters and maximum distance of extrapolation from data points. If a computer assisted estimation method was chosen include a description of computer software and parameters used. • The availability of check estimates, previous estimates and/or mine production records and whether the Mineral Resource estimate takes appropriate account of such data. • The assumptions made regarding recovery of by-products. • Estimation of deleterious elements or other non-grade variables of economic signifcance (eg sulphur for acid mine drainage characterisation). • In the case of block model interpolation, the block size in relation to the average sample spacing and the search employed. • Any assumptions behind modelling of selective mining units. • Any assumptions about correlation between variables. • Description of how the geological interpretation was used to control the resource estimates. • Discussion of basis for using or not using grade cutting or capping. • The process of validation, the checking process used, the comparison of model data to drill hole data, and use of reconciliation data if available. |
• All modelling and estimation work undertaken by Metals X is carried out in three dimensions via Surpac Vision. • After validating the drillhole data to be used in the estimation, interpretation of the orebody is undertaken in sectional and / or plan view to create the outline strings which form the basis of the three dimensional orebody wireframe. Wireframing is then carried out using a combination of automated stitching algorithms and manual triangulation to create an accurate three dimensional representation of the sub-surface mineralised body. • Drillhole intersections within the mineralised body are defned, these intersections are then used to fag the appropriate sections of the drillhole database tables for compositing purposes. Drillholes are subsequently composited to allow for grade estimation. In all aspects of resource estimation the factual and interpreted geology was used to guide the development of the interpretation. • Once the sample data has been composited, a statistical analysis is undertaken to assist with determining estimation search parameters, top-cuts etc. Variographic analysis of individual domains is undertaken to assist with determining appropriate search parameters. Which are then incorporated with observed geological and geometrical features to determine the most appropriate search parameters. • An empty block model is then created for the area of interest. This model contains attributes set at background values for the various elements of interest as well as density, and various estimation parameters that are subsequently used to assist in resource categorisation. The block sizes used in the model will vary depending on orebody geometry, minimum mining units, estimation parameters and levels of informing data available. • Grade estimation is then undertaken, with ordinary kriging estimation method is considered as standard, although in some circumstances where sample populations are small, or domains are unable to be accurately defned, inverse distance weighting estimation techniques will be used. Both by-product and deleterious elements are estimated at the time of primary grade estimation if required. It is assumed that by-products correlate well with gold. There are no assumptions made about the recovery of by-products. • The resource is then depleted for mining voids and subsequently classifed in line with JORC guidelines utilising a combination of various estimation derived parameters and geological / mining knowledge. • This approach has proven to be applicable to Metals X’s gold assets. • Estimation results are routinely validated against primary input data, previous estimates and mining output. • Good reconciliation between mine claimed fgures and milled fgures was routinely achieved during pastproduction history. |

| Bulk density | • Whether assumed or determined. If assumed, the basis for the assumptions. If determined, the method used, whether wet or dry, the frequency of the measurements, the nature, size and representativeness of the samples. • The bulk density for bulk material must have been measured by methods that adequately account for void spaces (vugs, porosity, etc), moisture and diferences between rock and alteration zones within the deposit. • Discuss assumptions for bulk density estimates used in the evaluation process of the diferent materials. |
• Bulk density of the mineralisation at the Tennant Creek Project is variable and is for the both lithology and alteration / mineralisation dependent. • For modern drilling, feld technicians perform density test-work on core samples on a campaign basis every three months. All density measurements have been determined using the simple water immersion technique.

The bulk of the data used in resource calculations at Renison has been gathered from diamond core. Three sizes have been used historically NQ2 (45.1mm nominal core diameter), LTK60 (45.2mm nominal core diameter) and LTK48 (36.1mm nominal core diameter), with NQ2 currently in use. This core is geologically logged and subsequently halved for sampling. Grade control holes may be whole-cored to streamline the core handling process if required. NQ and HQ core sizes have been recorded as being used at Mount Bischof. This core is geologically logged and subsequently halved for sampling. There is no diamond drilling for the Rentails Project. • Face Sampling Each development face / round is horizontally chip sampled at Renison. The sampling intervals are domained by geological constraints (e.g. rock type, veining and alteration / sulphidation etc.). Samples are taken in a range from 0.3m up to 1.2m in waste / mullock. All exposures within the orebody are sampled. A similar process would have been followed for historical Mount Bischof face sampling. There is no face sampling for the Rentails Project. • Sludge Drilling Sludge drilling at Renison is performed with an underground production drill rig. It is an open hole drilling method using water as the fushing medium, with a 64mm (nominal) hole diameter. Sample intervals are ostensibly the length of the drill steel. Holes are drilled at sufcient angles to allow fushing of the hole with water following each interval to prevent contamination. There is no sludge drilling for the Mount Bischof Project. There is no sludge drilling for the Rentails Project. • RC Drilling RC drilling has been utilised at Mount Bischof. Drill cuttings are extracted from the RC return via cyclone. The underfow from each interval is transferred via bucket to a four tiered rife splitter, delivering approximately three kilograms of the recovered material into calico bags for analysis. The residual material is retained on the ground near the hole.

| • Percussion Drilling This drilling method was used for the Rentails project and uses a rotary tubular drilling cutter which was driven percussively into the tailings. The head of the cutting tube consisted of a 50mm diameter hard tipped cutting head inside which were ftted 4 spring steel fngers which allowed the core sample to enter and then prevented it from falling out as the drill tube was withdrawn from the drill hole. There is no percussion drilling for the Renison Project. There is no percussion drilling for the Mount Bischof Project. • All geology input is logged and validated by the relevant area geologists, incorporated into this is assessment of sample recovery. No defned relationship exists between sample recovery and grade. Nor has sample bias due to preferential loss or gain of fne or coarse material been noted. |

Core (or costean, channel, etc) photography. • The total length andpercentage of the relevant intersections logged |
• Diamond core is logged geologically and geotechnically. • RC chips are logged geologically. • Development faces are mapped geologically. • Logging is quantitative in nature. • All holes are logged completely, all faces are mapped completely. |
| Sub-sampling techniques and sample preparation |
• If core, whether cut or sawn and whether quarter, half or all core taken. • If non-core, whether rifed, tube sampled, rotary split, etc and whether sampled wet or dry. • For all sample types, the nature, quality and appropriateness of the sample preparation technique. • Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. • Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for feld duplicate/second-half sampling. • Whether sample sizes are appropriate to the grain size of the material being sampled. |
• Drill core is halved for sampling. Grade control holes may be whole-cored to streamline the core handling process if required • Samples are dried at 90°C, then crushed to <3mm. Samples are then rife split to obtain a sub-sample of approximately 100g which is then pulverized to 90% passing 75um. 2g of the pulp sample is then weighed with 12g of reagents including a binding agent, the weighed sample is then pulverized again for one minute. The sample is then compressed into a pressed powder tablet for introduction to the XRF. This preparation has been proven to be appropriate for the style of mineralisation being considered. • QA/QC is ensured during the sub-sampling stages process via the use of the systems of an independent NATA / ISO accredited laboratory contractor. • The sample size is considered appropriate for the grain size of the material being sampled. • The un-sampled half of diamond core is retained for check sampling if required. • For RC chips regular feld duplicates are collected and analysed for signifcant variance to primaryresults. |
| Quality of assay data and laboratory tests |
• The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. • Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. |
• Assaying is undertaken via the pressed powder XRF technique. Sn, As and Cu have a detection limit 0.01%, Fe and S detection limits are 0.1%. These assay methodologies are appropriate for the resource in question. • All assay data has built in quality control checks. Each XRF batch of twenty consists of one blank, one internal standard, one duplicate and a replicate, anomalies are re-assayed to ensure quality control. • Specifc gravity / density values for individual areas are routinely sampled during all diamond drillingwhere material is competent enough to do so. |

• Drilling in the underground environment at Renison is nominally carried-out on 40m x 40m spacing in the south of the mine and 25m, x 25m spacing in the north of the mine prior to mining occurring. A lengthy history of mining has shown that this data spacing is appropriate for the Mineral Resource estimation process and to allow for classifcation of the resource as it stands. • Drilling at Mount Bischof is variably spaced.

Native title interests are recorded against the Queensland tenements. • Tasmanian tenements are held by the Bluestone Mines Tasmania Joint Venture of which Metals X has 50% ownership. • No royalties above legislated state royalties apply for the Tasmanian tenements. • Bluestone Mines Tasmania Joint Venture operates in accordance with all environmental conditions set down as conditions for grant of the mining leases. • There are no known issues regarding security of tenure. • The Renison and Mount Bischof areas have an exploration and production history in excess of 100 years. • Bluestone Mines Tasmania Joint Venture work has generally confrmed the veracity of historic exploration data. • Renison is one of the world’s largest operating underground tin mines and Australia’s largest primary tin producer. Renison is the largest of three major Skarn, carbonate replacement, pyrrhotite-cassiterite deposits within western Tasmania. The Renison Mine area is situated in the Dundas Trough, a province underlain by a thick sequence of Neoproterozoic-Cambrian siliciclastic and volcaniclastic rocks. At Renison there are three shallow-dipping dolomite horizons which host replacement mineralisation. • Mount Bischof is the second of three major Skarn, carbonate replacement, pyrrhotite- cassiterite deposits within western Tasmania. The Mount Bischof Mine area is situated within the Dundas Trough, a province underlain by a thick sequence of Neoproterozoic-Cambrian siliciclastic and volcaniclastic rocks. At Mount Bischof folded and faulted shallow-dipping dolomite horizons host replacement mineralisation with fuid interpreted to be sourced from the forceful emplacement of a granite ridge and associated porphyry intrusions associated with the Devonian Meredith Granite, which resulted in the complex brittle / ductile deformation of the host rocks. Lithologies outside the current mining area are almost exclusively metamorphosed siltstones. Major porphyry dykes and faults such as the Giblin and Queen provided the major focus for ascending hydrothermal fuids from a buried ridge of the Meredith Granite. Mineralisation has resulted in tin-rich sulphide replacement in the dolomite lodes, greisen and sulphide lodes in the porphyry and fault / vein lodes in the major faults. All lodes contain tin as cassiterite within sulphide mineralisation with some coarse cassiterite as veins throughout the lodes. • The Rentails resource is contained within three Tailing Storage Facilities (TSF’s) that have been built up from the processing of tin ore at the Renison Bell mine over the period 1968 to 2013. |

| Database integrity | • Measures taken to ensure that data has not been corrupted by, for example, transcription or keying errors, between its initial collection and its use for Mineral Resource estimation purposes. • Data validation procedures used. |
• Drillhole data is stored in a Maxwell’s DataShed system based on the Sequel Server platform which is currently considered “industry standard”. • As new data is acquired it passes through a validation approval system designed to pick up any signifcant errors before the information is loaded into the master database. The information is uploaded by a series of Sequel routines and is performed as required. The database contains diamond drilling (including geotechnical and specifc gravity data), face chip and sludge drilling data and some associated metadata. By its nature this database is large in size, and therefore exports from the main database are undertaken (with or without the application of spatial and various other flters) to create a database of workable size, preserve a snapshot of the database at the time of orebody modelling and interpretation and preserve the integrityof the master database. |

• Mining has occurred since 1800’s providing signifcant confdence in the currently geological interpretation across all projects. • No alternative interpretations are currently considered viable. • Geological interpretation of the deposit was carried out using a systematic approach to ensure that the resultant estimated Mineral Resource fgure was both sufciently constrained, and representative of the expected sub-surface conditions. In all aspects of resource estimation the factual and interpreted geology was used to guide the development of the interpretation. • The architecture of the Renison horst / graben system is the dominant control on geological and grade continuity. • Similarly at Mount Bischof the extent of intrusive felsic dykes in proximity to carbonate horixons control the continuity of grade within the system. • The depositional historyof Rentails is well documented. |
| Dimensions | • The extent and variability of the Mineral Resource expressed as length (along strike or otherwise), plan width, and depth below surface to the upper and lower limits of the Mineral Resource. |
• Renison has currently been mined over a strike length of >1,950m, a lateral extent of >1,250m and a depth of over 1,100m. • Mount Bischof mineralisation has currently been defned over a strike length of >600m, a lateral extent of >250m and a depth of >250m. • Rentails is deposited in three adjacent TSFs which have and aggregate length of approximately 1.8km and a width at the widestpoint of circa 1km. Maximum depth is in excess of 20m. |

If a computer assisted estimation method was chosen include a description of computer software and parameters used. • The availability of check estimates, previous estimates and/or mine production records and whether the Mineral Resource estimate takes appropriate account of such data. • The assumptions made regarding recovery of by-products. • Estimation of deleterious elements or other non-grade variables of economic signifcance (eg sulphur for acid mine drainage characterisation). • In the case of block model interpolation, the block size in relation to the average sample spacing and the search employed. • Any assumptions behind modelling of selective mining units. • Any assumptions about correlation between variables. • Description of how the geological interpretation was used to control the resource estimates. • Discussion of basis for using or not using grade cutting or capping. • The process of validation, the checking process used, the comparison of model data to drill hole data, and use of reconciliation data if available. |
• All modelling and estimation work undertaken by Bluestone is carried out in three dimensions via Surpac Vision. • After validating the drillhole data to be used in the estimation, interpretation of the orebody is undertaken in sectional and / or plan view to create the outline strings which form the basis of the three dimensional orebody wireframe. Wireframing is then carried out using a combination of automated stitching algorithms and manual triangulation to create an accurate three dimensional representation of the sub-surface mineralised body. • Drillhole intersections within the mineralised body are defned, these intersections are then used to fag the appropriate sections of the drillhole database tables for compositing purposes. Drillholes are subsequently composited to allow for grade estimation. In all aspects of resource estimation the factual and interpreted geology was used to guide the development of the interpretation. • Once the sample data has been composited, a statistical analysis is undertaken to assist with determining estimation search parameters, top-cuts etc. Variographic analysis of individual domains is undertaken to assist with determining appropriate search parameters. Which are then incorporated with observed geological and geometrical features to determine the most appropriate search parameters. • An empty block model is then created for the area of interest. This model contains attributes set at background values for the various elements of interest as well as density, and various estimation parameters that are subsequently used to assist in resource categorisation. The block sizes used in the model will vary depending on orebody geometry, minimum mining units, estimation parameters and levels of informing data available. • Grade estimation is then undertaken, with ordinary kriging estimation method is considered as standard, although in some circumstances where sample populations are small, or domains are unable to be accurately defned, inverse distance weighting estimation techniques will be used. Both by-product and deleterious elements are estimated at the time of primary grade estimation. It is assumed that by-products correlate well with tin. There are no assumptions made about the recovery of by-products. • The resource is then depleted for mining voids and subsequently classifed in line with JORC guidelines utilising a combination of various estimation derived parameters and geological / mining knowledge. • This approach has proven to be applicable to Metals X’s tin assets. • Estimation results are routinely validated against primary input data, previous estimates and mining output. • Good reconciliation between mine claimed fgures and milled fgures is routinelyachieved. |

• Not considered for Mineral Resource. Applied during the Reserve generation process. |
| Environmental factors or assumptions |
• Assumptions made regarding possible waste and process residue disposal options. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider the potential environmental impacts of the mining and processing operation. While at this stage the determination of potential environmental impacts, particularly for a greenfelds project, may not always be well advanced, the status of early consideration of these potential environmental impacts should be reported. Where these aspects have not been considered this should be reported with an explanation of the environmental assumptions made. |

| Bulk density | • Whether assumed or determined. If assumed, the basis for the assumptions. If determined, the method used, whether wet or dry, the frequency of the measurements, the nature, size and representativeness of the samples. • The bulk density for bulk material must have been measured by methods that adequately account for void spaces (vugs, porosity, etc), moisture and diferences between rock and alteration zones within the deposit. • Discuss assumptions for bulk density estimates used in the evaluation process of the diferent materials. |
• Bulk density of the mineralisation at Renison and Mount Bischof is variable. Bulk density sampling is undertaken via assessments of drill core (BMTJV practice is to undertake bulk density determinations on a representative selection of drill core sent for assay), and are reviewed constantly (BMTJV practice is to collect check SG samples as a regular part of the mining cycle). Where no drill core or other direct measurements are available, SG factors have been assumed based on similarities to other zones of mineralisation. • Given the volume of the TSF’s are known, and the tonnage of tailings material deposited into the dams was recorded, the insitu bulk density of the Rentails resource has been back- calculated. |
| Classifcation | • The basis for the classifcation of the Mineral Resources into varying confdence categories. • Whether appropriate account has been taken of all relevant factors (ie relative confdence in tonnage/grade estimations, reliability of input data, confdence in continuity of geology and metal values, quality, quantity and distribution of the data). • Whether the result appropriatelyrefects the Competent Person’s view of the deposit. |
• Resources are classifed in line with JORC guidelines utilising a combination of various estimation derived parameters, the input data and geological / mining knowledge. • This approach considers all relevant factors and refects the Competent Person’s view of the deposit. |
| Audits or reviews | • The results of any audits or reviews of Mineral Resource estimates. |
• Resource estimates are peer reviewed by the site technical team as well as Metals X’s Corporate technical team. |

• The Renison mine predominantly applies an up-hole benching with in some cases post fll and cemented aggregate fll to fll voids. The mining method has been successfully applied over the past decade with small tweaks and geotechnical considerations progressively applied. • Mining dilution for the Mining Reserve is generally 25% at zero grade. • A minimum mining width of underground development is 3.5m and for underground stoping a minimum width of 1.5m and resource models are diluted to these limits before dilution applied. • A mining recovery 80% of the material developed and/or stoped is applied. • No Inferred resources are included within either the Reserve or the mine plan. • Rentails resources have been converted to reserve via a DFS study. • Rentails will be mined via a combination of dredging and monitoring. • Mining dilution at Rentails is minimal. • Mining recovery at Rentails will exceed 95%. • No Inferred resources are included within either the Rentails Reserve or the mine plan. • No reserve is stated for Mount Bischof. |

• The Renison mine produces a tin concentrate of grade varying between 50- 60 % Sn with internal process designed to reduce penalty metals such as iron, sulphur, tungsten and copper. • The metallurgical process is complex and applies several stages of gravity-type concentration as well as sulphide and oxide fotation, regrinding and acid leach methods. The method is proved and has successfully operated for over 45 years. • The metallurgical recovery as estimated based on regression analysis of grade recovery curves from the actual processing of ores in the plant. • Metallurgical recoveries on the various ore and grades were considered as part of the cut-of grade analysis. • The process proposed by Rentails project is to regrind the ores to a fner grind, the pre- concentration using sulphide and oxide fotation, and high-g-force gravity separation to produce a low-grade concentrate which is planned to be processed using an Ausmelt process to fume the tin to a high grade concentrate tap out a copper matte. • No reserve is stated for Mount Bischof. |

These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fre assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. • Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face- sampling bit or other type, whether core is oriented and if so, by what method, etc). • Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the samples. • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fne/coarse material. |
A small portion of the data used in resource calculations at the Central Musgrave Project (CMP) has been gathered from diamond core. This core is geologically logged prior to sampling. • RC Drilling RC drilling has been utilised extensively at the CMP. Drill cuttings are extracted from the RC return via cyclone. The underfow from each interval is transferred via bucket to a four tiered rife splitter, delivering approximately three kilograms of the recovered material into calico bags for analysis. The residual material is retained on the ground near the hole. Composite samples are obtained from the residue material for initial analysis, with the split samples remaining with the individual residual piles until required for re-split analysis or eventual disposal. • Historial A variety of drilling methods were employed by INCO, including churn drilling (102 holes) DDH (19 holes) RAB Drilling (2,643 holes) Vacuum (77 holes) Becker Drilling (102 holes). • Sample recovery from early drilling by INCO is not known. Sample recovery from RC drilling carried out from RC drilling after 2001 was generally very good, except where the drill encountered strong water fow from the hole. • All geology input is logged and validated by the relevant area geologists, incorporated into this is assessment of sample recovery. No defned relationship exists between sample recovery and grade. Nor has sample bias due to preferential loss or gain of fne or coarse material been noted. |

| Database integrity | • Measures taken to ensure that data has not been corrupted by, for example, transcription or keying errors, between its initial collection and its use for Mineral Resource estimation purposes. • Data validation procedures used. |
• Drillhole data is stored in a Maxwell’s DataShed system based on the Sequel Server platform which is currently considered “industry standard”. • As new data is acquired it passes through a validation approval system designed to pick up any signifcant errors before the information is loaded into the master database. The information is uploaded by a series of Sequel routines and is performed as required. The database contains diamond drilling (including geotechnical and specifc gravity data), and some associated metadata. By its nature this database is large in size, and therefore exports from the main database are undertaken (with or without the application of spatial and various other flters) to create a database of workable size, preserve a snapshot of the database at the time of orebody modelling and interpretation and preserve the integrity of the master database. |
| Site visits | • Comment on any site visits undertaken by the Competent Person and the outcome of those visits. • If no site visits have been undertaken indicate whythis is the case. |

• Confdence in the geological model used to constrain the Wingellina estimate is high, with the genetic model for lateritic nickel development well understood. Logged geology has been used to drive the mineralisation interpretation, with the base of laterite defned with drill holes, or its level on a given section interpreted from surrounding drill sections. Continuity of the interpretation across and along the Wingellina deposit is for the most part good, with intersections of hard rock in drill holes, and well mapped outcropping basement the primary causes of breaks within the mineralised horizon. • No alternative interpretations are currently considered viable. • Geological interpretation of the deposit was carried out using a systematic approach to ensure that the resultant estimated Mineral Resource fgure was both sufciently constrained, and representative of the expected sub-surface conditions. In all aspects of resource estimation the factual and interpreted geology was used to guide the development of the interpretation. • The protolithology is the dominant control on grade continuity at the CMP. Structural controls which infuence depth of weatheringare secondarycontrols ongrade distribution. |

• All modelling and estimation work undertaken was carried out in three dimensions via either Vulcan or Surpac Vision. • After validating the drillhole data to be used in the estimation, interpretation of the orebody is undertaken in sectional and / or plan view to create the outline strings which form the basis of the three dimensional orebody wireframe. Wireframing is then carried out using a combination of automated stitching algorithms and manual triangulation to create an accurate three dimensional representation of the sub-surface mineralised body. • Drillhole intersections within the mineralised body are defned, these intersections are then used to fag the appropriate sections of the drillhole database tables for compositing purposes. Drillholes are subsequently composited to allow for grade estimation. In all aspects of resource estimation the factual and interpreted geology was used to guide the development of the interpretation. • Once the sample data has been composited, a statistical analysis is undertaken to assist with determining estimation search parameters, top-cuts etc. Variographic analysis of individual domains is undertaken to assist with determining appropriate search parameters. Which are then incorporated with observed geological and geometrical features to determine the most appropriate search parameters. • An empty block model is then created for the area of interest. This model contains attributes set at background values for the various elements of interest as well as density, and various estimation parameters that are subsequently used to assist in resource categorisation. The block sizes used in the model will vary depending on orebody geometry, minimum mining units, estimation parameters and levels of informing data available. • Grade estimation is then undertaken, with ordinary kriging estimation method is considered as standard, although in some circumstances where sample populations are small, or domains are unable to be accurately defned, inverse distance weighting estimation techniques will be used. Both by-product and deleterious elements are estimated at the time of primary grade estimation if required. It is assumed that by-products correlate well with gold. There are no assumptions made about the recovery of by-products. • The resource is then depleted for mining voids and subsequently classifed in line with JORC guidelines utilising a combination of various estimation derived parameters and geological / mining knowledge. • This approach has proven to be applicable to Metals X’s nickel assets. • Estimation results are routinely validated against primary input data, previous estimates and mining output. |
| Moisture | • Whether the tonnages are estimated on a dry basis or with natural moisture, and the method of determination of the moisture content. |
• Tonnage estimates are dry tonnes. |
| Cut-of parameters | • The basis of the adopted cut-of grade(s) or quality parameters applied. |
• The resource reporting cut-of grade is 0.5% Ni. • The reporting cut-of used was based on MLX’s current interpretation of commodity markets, and to allowpeergroupcomparison. |

| Mining factors or assumptions | • Assumptions made regarding possible mining methods, minimum mining dimensions and internal (or, if applicable, external) mining dilution. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential mining methods, but the assumptions made regarding mining methods and parameters when estimating Mineral Resources may not always be rigorous. Where this is the case, this should be reported with an explanation of the basis of the mining assumptions made. |
• Not considered for Mineral Resource. Applied during the Reserve generation process. |
| Metallurgical factors or assumptions |
• The basis for assumptions or predictions regarding metallurgical amenability. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential metallurgical methods, but the assumptions regarding metallurgical treatment processes and parameters made when reporting Mineral Resources may not always be rigorous. Where this is the case, this should be reported with an explanation of the basis of the metallurgical assumptions made. |
• Not considered for Mineral Resource. Applied during the Reserve generation process. |
| Environmental factors or assumptions |
• Assumptions made regarding possible waste and process residue disposal options. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider the potential environmental impacts of the mining and processing operation. While at this stage the determination of potential environmental impacts, particularly for a greenfelds project, may not always be well advanced, the status of early consideration of these potential environmental impacts should be reported. Where these aspects have not been considered this should be reported with an explanation of the environmental assumptions made. |
• MLX operates in accordance with all environmental conditions set down as conditions for grant of the respective leases. |
| Bulk density | • Whether assumed or determined. If assumed, the basis for the assumptions. If determined, the method used, whether wet or dry, the frequency of the measurements, the nature, size and representativeness of the samples. • The bulk density for bulk material must have been measured by methods that adequately account for void spaces (vugs, porosity, etc), moisture and diferences between rock and alteration zones within the deposit. • Discuss assumptions for bulk density estimates used in the evaluation process of the diferent materials. |
• Sampling of HQ diamond drill core was used to determine the dry density of laterite ore. Average measured dry density is 1.28t/m3. • A total of 281 triple-tube HQ core samples were collected immediately from the core barrel and measured for bulk density on site. The core length was measured for diameter and length (square-cut ends), dried for 24 hours in a gas oven at 120°C, and weighed. • Density was calculated by dividing the weight (kg) of dry sample by the volume of the core piece. |
| Classifcation | • The basis for the classifcation of the Mineral Resources into varying confdence categories. • Whether appropriate account has been taken of all relevant factors (ie relative confdence in tonnage/grade estimations, reliability of input data, confdence in continuity of geology and metal values, quality, quantity and distribution of the data). • Whether the result appropriatelyrefects the Competent Person’s view of the deposit. |
• Resources are classifed in line with JORC guidelines utilising a combination of various estimation derived parameters, the input data and geological / mining knowledge. • This approach considers all relevant factors and refects the Competent Person’s view of the deposit. |
| Audits or reviews | • The results of any audits or reviews of Mineral Resource estimates. |
• Resource estimates are peer reviewed by the site technical team as well as Metals X’s Corporate technical team. |

| Discussion of relative accuracy/ confdence |
• Where appropriate a statement of the relative accuracy and confdence level in the Mineral Resource 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 resource within stated confdence limits, or, if such an approach is not deemed appropriate, a qualitative discussion of the factors that could afect the relative accuracy and confdence 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. • These statements of relative accuracy and confdence of the estimate should be compared withproduction data, where available. |

| Mineral Resource estimate for conversion to Ore Reserves |
• Description of the Mineral Resource estimate used as a basis for the conversion to an Ore Reserve. • Clear statement as to whether the Mineral Resources are reported additional to, or inclusive of, the Ore Reserves. |
At all projects, all resources that have been converted to reserve are classifed as either an Indicated or Measured Resource. Indicated Resources are only upgraded to Probable Reserves after adding appropriate modifying factors. Some Measured Resource may be classifed as Proven Reserves and some is classifed as Probable Reserve based on whether is capitallyor fullydeveloped. |
| Site visits | • Comment on any site visits undertaken by the Competent Person and the outcome of those visits. • If no site visits have been undertaken indicate whythis is the case. |
• Irregular site visits have been undertaken. The reserve has remained consistent since the 2008 Feasibility Study was completed. |
| Study status | • The type and level of study undertaken to enable Mineral Resources to be converted to Ore Reserves. • The Code requires that a study to at least Pre-Feasibility Study level has been undertaken to convert Mineral Resources to Ore Reserves. Such studies will have been carried out and will have determined a mine plan that is technically achievable and economically viable, and that material ModifyingFactors have been considered |
• A Feasibility Study utilising a combination of internal and external expertise has been undertaken to allow the conversion of Mineral Resources to Ore Reserves. |
| Cut-of parameters | • The basis of the cut-of grade(s) or quality parameters applied. |
• The cut-of grade used for inclusion in the CMP Reserve were determined through the Feasibility Study process. • Cobalt co-product revenue is considered bythe FS. |

For example, the application of statistical or geostatistical procedures to quantify the relative accuracy of the reserve within stated confdence limits, or, if such an approach is not deemed appropriate, a qualitative discussion of the factors which could afect the relative accuracy and confdence 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 confdence discussions should extend to specifc 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 confdence of the estimate should be compared with production data, where available. |
• All currently reported reserve calculations are considered representative on a global scale. • Only material considered as part of the Pre-feasibility study has been included as part of the reserve statement. • Limited modifying factors have been applied due to the massive nature of the deposit and the closeness to the surface. |
