OVERVIEW
Group Total Recordable Injury Frequency (TRIF[1] ) at 31 December was in line with the September quarter at 9.4 as the safety improvement plan compliance continues to improve.
COVID-19 continues to be a significant focus for the business and the formal crisis management response protocols remain activated. Whilst the impact to operational performance has not been material to date, positive cases in the community around Cowal and Red Lake and isolation of close contacts has resulted in periods where up to 15% of the workforce has been unavailable.
Evolution’s FY21 Sustainability Report and 2021 Modern Slavery Statement were published during the quarter, and two shared value projects with the Galari Agricultural Company and the University of Queensland’s Research for COVID-19 Immune Response Using Gold were approved. Our focus on ESG performance was recognised with an improved rating from ISS ESG and confirmation of continued inclusion in S&P Global Dow Jones Sustainability Index Australia, ranking Evolution among the top performing Australian mining companies for corporate sustainability and one of only three gold mining companies in this category.
Group gold production for the December 2021 quarter was 148,084 ounces (Sep qtr: 170,681oz) at an AISC of A$1,347/oz (Sep qtr: A$1,413/oz). Production for the quarter excludes Mt Carlton which was divested effective 1 October 2021. Weatherrelated impacts at Cowal and Mt Rawdon restricted access to higher grade open pit ore although Cowal was still able to achieve its plan. Evolution provided an update on Red Lake on 17 November 2021 that the December 2021 quarter would be similar to the previous quarter.
Evolution delivered a 5% higher mine operating cash flow of A$202.7 million (Sep qtr: A$193.7 million) during the quarter. On a like for like basis, excluding the divested Mt Carlton asset, this was a 13% increase. Net mine cash flow was A$53.0 million (Sep qtr: A$67.5 million). Mine capital investment for the quarter was on plan at A$147.9 million (Sep qtr: A$125.2 million). The majority of this capital relates to the Cowal Underground and Red Lake. As at 31 December 2021, Evolution had cash in the bank of A$1,150.3 million and net debt[2] of A$449.2 million.
Ernest Henry continues to be Evolution’s most cash generative asset delivering net mine cash flow of A$79.5 million in the quarter. Evolution has now taken full ownership of Ernest Henry from 6 January 2022. Evolution paid Glencore A$800 million with a further A$200 million due and payable on 6 January
- Ernest Henry is expected to generate immediate benefits from increased copper production via increased cash flow and lower Group AISC. The operation also has attractive growth potential below the current operating footprint which is the subject of a pre-feasibility study (PFS). Mineralisation has also been intersected 400m vertically below the PFS area and is open at depth.
At Cowal, capital stripping of Stage H was completed which commenced access to higher grade ore. The Integrated Waste Landform (IWL) Stage 2 was completed and deposition commenced. The underground project continues to progress on time and on budget.
At Red Lake, development rates are now consistently above 1,200m/month which will enable the operation to establish additional mining fronts to support increased production for the remainder of FY22. Improvements have been implemented to reduce stope cycle times and ore dilution which is expected to translate into a material improvement in production for the remainder of FY22.
At Mungari, the first ore processing campaign for East Kundana was successfully completed. Integration activities are progressing well to bring the operating teams together and to remove duplication of activities, but access to labour to fill roles has been challenging. Cost reduction programs are now delivering savings which will continue to ramp up in the second half of FY22.
At Mt Rawdon, significant wet weather impacted access to ore in the pit with the operation forced to process material from the low-grade stockpile.
On 15 December 2021 the sale of Mt Carlton to Navarre Minerals Limited (ASX:NML) was completed. The upfront consideration of A$40 million comprised A$26.8 million in cash and A$13.2 million share consideration[3] . Additional contingent payments of up to A$50 million are linked to success at Crush Creek and gold price. Navarre’s economic interest in Mt Carlton commenced on 1 October 2021.
At the Cue Joint Venture, diamond drilling identified multiple new northwest trending lodes each with strike lengths of over 200m and open in all directions. The key result was 4.26m grading 41.47g/t gold from 160.74m (21MODD025) including 0.41m grading 400.2g/t gold from 160.74m at West Island.
At Red Lake, results from diamond drilling targeting a repeat of the famous High Grade Zone returned a significant intercept at Lower Campbell including 0.75m grading 344.2g/t gold (D48069).
-
A$13.2 million consideration was 176,565,396 Navarre shares based on the share placement price of A$0.075 per share. Equates to a 12.9% shareholding in Navarre Minerals Limited

OPERATIONS
Cowal, New South Wales (100%)
Cowal produced 60,371oz of gold at an AISC of A$998/oz (Sep qtr: 52,513oz, AISC A$1,304/oz).
Mine operating cash flow for the quarter was A$80.5 million (Sep qtr: A$48.5 million). Net mine cash flow was A$17.0 million (Sep qtr: A$5.4 million), post sustaining capital of A$3.3 million and major capital of A$60.2 million.
Mining of Stage H progressed with completion of the major waste stripping and access to higher grade ore commencing in the quarter. Total ore mined was 46% higher than the previous quarter.
The performance was achieved despite operational impacts from both near-record monthly rainfall in November (175mm against 37mm long-term average); associated regional flooding in nearby Forbes; and resourcing impacts caused by COVID19.
Underground development advanced with 1,033m (Sep qtr: 1,056m) achieved during the quarter for a total of 3,218m, with a second development drill mobilised to site late in the quarter. Underground diamond drilling continued with two drill rigs for 14.6km (Sep qtr: 10.0km) of a total of 37km, targeting resource definition for early production areas. Ongoing mine design optimisation was completed in preparation for mining execution ramp-up, long-lead items associated with primary ventilation were purchased with installing underway, package engineering advanced, and the primary mining contract tender is nearing completion for award in the coming quarter.
Construction of the IWL progressed with completion of stage 2 and deposition to date has performed well.

Ernest Henry, Queensland
(Economic interest up to 31 December 2021; 100% gold and 30% copper production)[1]
Evolution’s interest in Ernest Henry delivered 21,093oz of gold and 4,119t of copper at a low AISC of negative A$882/oz (Sep qtr: 23,882oz Au and 5,598t Cu at negative A$1,345/oz). The higher AISC was primarily driven by lower copper revenue. Copper sales in the quarter were 4,126t at an average copper price of A$14,199/t.
Operating mine cash flow for the quarter was A$85.9 million (Sep qtr: A$86.6 million). Ernest Henry generated a net mine cash flow for Evolution of A$79.5 million (Sep qtr: A$80.0 million), post sustaining capital of A$6.4 million (Sep qtr: A$6.6 million).
Ore mined was 1,636kt at an average grade of 0.50g/t gold and 1.04% copper. Underground lateral development was 2,294m, which includes 1,163m of operating development, 642m of capital development and 489m of rehabilitation development. Ore processed was lower this quarter due to a planned plant shutdown, with 1,614kt processed at an average grade of 0.47g/t gold and 0,98% copper. Gold recovery of 88.0% and copper recovery of 94.3% was achieved with mill utilisation at 85.3%.
Following the completion of the acquisition of Ernest Henry on 6 January, Evolution will report 100% of the operating performance from 1 January 2022 with material favourable impacts of higher copper production on cash flows and lower AISC per ounce.
The PFS (including mine development and drilling activities) has commenced with completion scheduled for H1 FY23. The concept study findings – provided confidence of a 4 5 years mine life extension to the 875mRL. As noted in the Exploration section, drilling has intersected mineralisation 400m vertically below the study area providing opportunity for further mine life extensions.

OPERATIONS
Red Lake, Ontario (100%)
Red Lake produced 19,832oz of gold at an AISC A$3,060/oz (Sep qtr: 23,768oz, AISC A$2,697/oz). Mine operating cash flow for the quarter was A$3.7 million (Sep qtr: A$4.8 million). Net mine cash flow was negative A$49.0 million (Sep qtr: negative A$36.8 million) post sustaining capital of A$13.9 million and major capital of A$36.9 million (Sep qtr: A$13.2 million and A$27.4 million respectively).
Underground development metres increased by 21% to 3,803m in the quarter (Sep qtr: 3,132m) with 1,200m/month development achieved each month during the December quarter. The operation is well positioned to continue the development rate ramp up to provide access to additional mining fronts going forward.
Ore processed was 176kt at 3.89g/t gold (Sep qtr: 174kt at 4.70g/t). December was a record month for Campbell mill achieving 58,311t throughput at 82.1tph with a daily record of 1,999t. Approval has been granted to lift the daily throughput restriction of 2,000tpd for a limited trial in the June 2022 half-year to support the Campbell mill expansion.
Ore mined was 15% higher than the prior quarter with 194kt mined at an average grade of 3.95g/t gold (Sep qtr: 169kt at 4.25g/t Au).
The operation continues to focus on lifting both mining rates and the grade of ore mined, with the following positive outcomes in the quarter:
-
Improved drill and blast practices have reduced drilling required by 30% and idle time by 60%
-
Stope turnover time has decreased by 25% and contributed to the 15% increase in ore tonnes mined
-
Stope dilution reduced overall by 3% for the quarter, with benefits from improvements to drill and blast and stope design implemented during the quarter resulting in an improved grade of 4.9g/t in the month of December
-
Reduced stope dilution has resulted in 5% improvement on grade reconciliation from last quarter. This is expected to continue to improve over coming quarters. The resource models are performing to plan.
Work continues to access new mining fronts with the first stope ore from the MMTP zone to be delivered in the March 2022 quarter and development is continuing to open up the Aviation zone to allow for mining to commence in the June 2022 half-year. Opening these new areas is key to lifting the mining tonnage rates.
The CYD decline progressed during the quarter achieving 368m development and first ore is on schedule for H1 FY23. Work continued at McFinley to enable bulk sample extraction by June 2022 with grade control drilling to improve orebody knowledge.

OPERATIONS
Mungari, Western Australia (100%)
Mungari produced 34,412 oz of gold at an AISC A$1,829/oz (Sep qtr: 34,765oz, AISC A$2,018/oz). Mine operating cash flow for the quarter was A$20.7 million (Sep qtr: A$21.10 million). Net mine cash flow was A$5.6 million (Sep qtr: negative A$0.8 million) post sustaining and major capital investment of A$15.2 million (Sep qtr: A$21.9 million).
Mungari attributable underground ore mined totalled 287kt at 3.61g/t gold (Sep qtr 253kt at 3.16g/t) and underground development was 2,717m (Sep qtr 2,562m). Open pit total material mined was 1,902kt (Sep qtr: 2,663kt). Open pit ore mined was 296kt at a grade of 1.08g/t gold (Sep qtr: 148kt at 1.12g/t).
The first ore processing campaign for East Kundana (EVN interest 51%) was completed as planned during the quarter, with 60,194t at 4.15g/t processed.
The operation continued to benefit from the acquisition of the Kundana assets with the average grade processed for the quarter increasing by 34% from 2.12g/t to 2.84g/t gold and the underground ore tonnes processed increasing to 67% of feed (Sep qtr: 54%). Plant throughput was 457kt (Sep qtr: 482kt) with the lower tonnes processed due to processing non-attributable tonnes from East Kundana. The operation is now advancing opportunities to improve mill throughput while maintaining recovery and reducing ore haulage distances from Kundana and East Kundana to the Mungari mill.
Mt Rawdon, Queensland (100%)
Mt Rawdon produced 12,377oz of gold at an AISC of A$1,842/oz (Sep qtr: 20,042oz at A$1,420/oz).
Mine operating cash flow was A$11.9 million (Sep qtr: A$18.7 million). Net mine cash flow of negative A$0.1 million (Sep qtr: A$9.3 million) was generated post sustaining and major capital investment of A$12.0 million (Sep qtr: A$9.5 million).
Ore processed was 884kt at an average grade of 0.52g/t gold (Sep qtr: 845kt at 0.83g/t Au). Plant recoveries were 85.7% and utilisation was 98.4% (Sep qtr: 88.8% and 95.7% respectively). Excessive weather events impacting ore production from the pit necessitated the feeding of lower grade stockpiled ore, impacting gold production and unit costs. This was partially offset by a strong up-time performance from the mill.
The focus for the March 2022 quarter is to bring the west wall cutback and east ramp system together, and progress mining towards the base of the pit.
Integration of the workforce is progressing well, but ongoing labour shortages in Western Australia continues to make filling positions challenging.

Highlights
-
At the Cue Joint Venture (EVN earning 75%), diamond drilling has identified multiple new northwest trending lodes oblique to the favourable dolerite host unit at West Island. The key result for the quarter was 4.26m grading 41.47g/t gold from 160.74m (21MODD025) including 0.41m grading 400.2g/t gold from 160.74m at West Island. Aircore drilling also continued to extend the mineralised dolerite envelope in the oxide profile
-
At Red Lake, underground drilling continued on the HGRD target which is an analogous structural and stratigraphic setting to the historically mined High Grade Zone. Results from the second drill hole of the program have returned a significant intercept of 0.75m grading 344.2g/t gold (D48069) at Lower Campbell, 200m away from mineralisation in the first hole reported in the September quarter
-
At Mungari, results were received from 12 new holes targeting mineralisation at Startrek east of the Rubicon-Hornet-Pegasus (RHP) corridor on the EKJV. A number of significant intercepts were returned with a best intersection of 0.8m grading 133.4g/t gold (STKDT21022)
-
Completion of the Ernest Henry acquisition on 6 January 2022 will enable the geological opportunity at depth to be further unlocked. Deepest drilling at the mine completed over the last two years encountered copper-gold mineralisation down to the 480mRL. The results delineate mineralisation 400m vertically below the lower limit of the extension project concept study

Discovery
Discovery drilling continued with one rig on the HGRD program targeting analogous structural and stratigraphic settings to the historically mined High Grade Zone. Two of three wide spaced holes have intercepted mineralisation across the interpreted extension of the R Zone structure, 500m down plunge of the current mining areas. Significant intersections returned from the latest hole D48069 include:
-
1.39m (1.26m etw) grading 72.3g/t gold from 860.3m (D48069)
-
0.83m (0.75m etw) grading 344.2g/t gold from 930.4m (D48069)
Mineralisation in this hole is located 200m from results in hole D48067RS reported previously in the September 2021 quarter which returned 8.63m (7.47m etw) grading 3.4 g/t gold[1] . A third hole returned no significant intercepts but highlighted the presence of the same geological structure. Results from all three holes signify a large untested area on the interpreted extension of the high-grade R Zone structure at Lower Campbell. Followup drilling is currently underway.

Ernest Henry, Queensland (100%)
The program of ore body extension drilling undertaken at Ernest Henry in the last two years comprises 136 underground diamond holes (for 44,538m) from the 1200mRL drill drive. The majority of drill holes were completed in support of the concept study to extend mining between the 1200mRL and 875mRL (Figure 5). Numerous holes completed below the 875mRL exploring future depth potential returned long intervals of coppergold mineralisation 400m vertically below the lower limit of the study area. The deepest holes intersect the mineralisation at the 480mRL and confirm mineralisation remains open at depth.

Cue Joint Venture (EVN earning 75% from Musgrave Minerals Ltd, ASX:MGV)
Results of diamond drilling continue to identify multiple, new northwest trending lodes oblique to the favourable dolerite host unit at West Island. Drilling will progress through the March quarter 2022, continuing to delineate the potential scale of mineralisation at West Island whilst beginning to focus on the economic potential of already identified structures.
Significant diamond core intercepts from the December 2021 quarter returned to date include:
-
4.26m grading 41.47g/t gold from 160.74m (21MODD025) including 0.41m grading 400.2g/t gold from 160.74m
-
6.00m grading 2.73g/t gold from 125m (21MODD033)
The results above confirm the geological model developed at West Island whereby mineralisation is hosted in multiple narrow lodes of limited strike extent constrained by the favourable dolerite host unit. The interval in 21MODD025 is encouraging because it indicates the potential for high grade mineralisation to exist within individual lodes (Figure 6). Hole 21MODD033 was drilled 200m north of 21MODD025 and is interpreted to have intersected a separate structure. Results are awaited for a further five diamond holes.
Highlights from the aircore drilling program are summarised below and in Figure 6. The results continue to delineate the favourable dolerite unit along strike which is important for hosting the better grades at West Island. Results from another 72 holes are pending.

Murchison Joint Venture (Evolution earning 80% from Enterprise Metals Limited, ASX:ENT)
Following geological and economic reviews, a decision was made to withdraw from the Murchison JV (Evolution earning 80%) effective 17 January 2022. The initial concepts for entering the JV and the subsequent targets that were budgeted and approved were effectively tested and did not meet the required criteria to progress further.
Further information on exploration results included in this report is provided in the Drill Hole Information Summary and JORC Code 2012 Table 1 presented in Appendix 1 of this report.

Forward looking statements
This report prepared by Evolution Mining Limited (or “the Company”) include forward looking statements. Often, but not always, forward looking statements can generally be identified by the use of forward looking words such as “may”, “will”, “expect”, “intend”, “plan”, “estimate”, “anticipate”, “continue”, and “guidance”, or other similar words and may include, without limitation, statements regarding plans, strategies and objectives of management, anticipated production or construction commencement dates and expected costs or production outputs.
Forward looking statements inherently involve known and unknown risks, uncertainties and other factors that may cause the Company’s actual results, performance and achievements to differ materially from any future results, performance or achievements. Relevant factors may include, but are not limited to, changes in commodity prices, foreign exchange fluctuations and general economic conditions, increased costs and demand for production inputs, the speculative nature of exploration and project development, including the risks of obtaining necessary licenses and permits and diminishing quantities or grades of reserves, political and social risks, changes to the regulatory framework within which the Company operates or may in the future operate, environmental conditions including extreme weather conditions, recruitment and retention of personnel, industrial relations issues and litigation.
Forward looking statements are based on the Company and its management’s good faith assumptions relating to the financial, market, regulatory and other relevant environments that will exist and affect the Company’s business and operations in the future. The Company does not give any assurance that the assumptions on which forward looking statements are based will prove to be correct, or that the Company’s business or operations will not be affected in any material manner by these or other factors not foreseen or foreseeable by the Company or management or beyond the Company’s control.
Although the Company attempts and has attempted to identify factors that would cause actual actions, events or results to differ materially from those disclosed in forward looking statements, there may be other factors that could cause actual results, performance, achievements or events not to be as anticipated, estimated or intended, and many events are beyond the reasonable control of the Company. Accordingly, readers are cautioned not to place undue reliance on forward looking statements. Forward looking statements in these materials speak only at the date of issue. Subject to any continuing obligations under applicable law or any relevant stock exchange listing rules, in providing this information the Company does not undertake any obligation to publicly update or revise any of the forward-looking statements or to advise of any change in events, conditions or circumstances on which any such statement is based.

| Sampling techniques | Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as downhole gamma sondes, 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 representation 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 completed this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases, more explanation may be required, such as where there is coarse gold that has inherent sampling problems, or |
Sampling of gold mineralisation at Red Lake Operation was undertaken using diamond core (surface and underground). All drill samples were logged prior to sampling. Diamond drill core was sampled to lithological, alteration and mineralisation related contacts. Sampling was carried out according to Red Lake Operations protocols and QAQC procedures which comply with industry best practice. All drill-hole collars were surveyed using a total station theodolite or total GPS. The sampling and assaying methods are appropriate for the orogenic mineralised system and are representative for the mineralisation style. The sampling and assaying suitability was validated using Red Lake Operations QAQC protocol and no instruments or tools requiring calibration were used as part of the sampling process. Diamond drill core sample intervals were based on geology to ensure a representative sample, with lengths ranging from 0.30 to 1m. Diamond drilling was half core sampled. All diamond core samples were dried, crushed and pulverised (total preparation) to produce a 50g charge for fire assay of Au. A suite of multi elements are determined using four-acid digest with ICP/MS and/or an ICP/AES finish for some sample intervals. |

Diamond core drilled was half core sampled and the remaining half was retained. Core is cut to preserve the bottom of hole orientation line, in some instance core may be quarter cut and send for analysis. Sample preparation of diamond samples was undertaken by external laboratories according to the sample preparation and assaying protocol established to maximise the representation of the Red Lake Operations mineralisation. Laboratories performance was monitored as part of Red Lake Operations QAQC procedure. Laboratory inspections were undertaken to monitor the laboratories compliance to the Red Lake Operations sampling and sample preparation protocol. The sample and size (1.5kg to 4kg) relative to the particle size (>90% passing 75um) of the material sampled is a commonly utilised practice for effective sample representation for gold deposits within the Orogenic Gold deposits of the Superior Craton Canada. Quality control procedures adopted to maximise sample representation for all sub-sampling stages include the collection of field and laboratory duplicates and the insertion of certified reference material as assay standards (1 in 20) and the insertion of blank samples (1 in 20) or at the geologist’s discretion. Coarse blank material is routinely submitted for assay and is inserted into each mineralised zone where possible and always after a sample identified as having visible gold. The quality control performance was monitored as part of Red Lake Operations QAQC procedure. The sample preparation has been conducted by commercial laboratories. All samples are oven dried (60°C), jaw crushed to 90% passing <2mm and riffle split to a maximum sample weight of 1kg as required. The primary sample is then pulverised in a one stage process, using a LM2 pulveriser, to a particle size of >90% passing 75um. Approximately 250g of the primary sample is extracted by spatula to a numbered paper pulp bag that is used for a 50g fire assay charge. The pulp is retained, and the bulk residue is disposed of after four months. |

| Criteria | Explanation | Commentary |
| Measures taken to ensure sample representation include the collection of field duplicates during diamond core sampling drilling at the geologist’s discretion and within the ore zone. Duplicate samples for diamond core are collected during the sample preparation crushing and pulverisation stage. A comparison of the duplicate sample vs. the primary sample assay result was undertaken as part of Red Lake Operations QAQC protocol. It is considered that all sub-sampling and lab preparations are consistent with other laboratories in Canada and are satisfactory for the intended purpose. The sample sizes are considered appropriate and in line with industry standards. |
||
| 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 (i.e. lack of bias) and precision have been established. |
The sampling preparation and assaying protocol used at Red Lake Operations was developed to ensure the quality and suitability of the assaying and laboratory procedures relative to the mineralisation types. No geophysical tools or other remote sensing instruments were utilised for reporting or interpretation of gold mineralisation. Fire assay is designed to measure the total gold within a sample. Fire assay has been confirmed as a suitable technique for orogenic type mineralisation. It has been extensively used throughout the North Western Ontario region. Screen fire assay have also been used to validate the fire assay techniques. Quality control samples were routinely inserted into the sampling sequence and also inserted at the discretion of the geologist either inside or around the expected zones of mineralisation. The intent of the procedure for reviewing the performance of certified standard reference material is to examine for any erroneous results (a result outside of the expected statistically derived tolerance limits) and to validate if required; the acceptable levels of accuracy and precision for all stages of the sampling and analytical process. Typically, batches which fail quality control checks are re-analysed. |
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. The use of twinned holes. Documentation of primary data, data entry procedures, data verification and data storage (physical and electronic) protocols. Discuss any adjustment to assay data |
Independent internal or external verification of significant intercepts is not routinely completed. The quality control / quality assurance (QAQC) process ensures the intercepts are representative for the orogenic gold systems. Half core and sample pulps are retained at Red Lake Operations for two years if further verification is required. The twinning of holes is not a common practice undertaken at Red Lake Operations. The face sample and drill hole data with the mill reconciliation data is of sufficient density to validate neighbouring samples. Data which is inconsistent with the known geology undergoes further verification to ensure its quality. All sample and assay information is stored utilising the acQuire database software system. Data undergoes QAQC validation prior to being accepted and loaded into the database. Assay results are merged when received electronically from the laboratory. The geologist reviews the database checking for the correct merging of results and that all data has been received and entered. Any adjustments to this data are recorded permanently in the database. Historical paper records (where available) are retained in the exploration and mining offices. No adjustments or calibrations have been made to the final assay data reported by the laboratory. |
| Location of data points |
Accuracy and quality of surveys used to locate drillholes (collar and downhole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Specification of the grid system used. Quality and adequacy of topographic control. |
Drill hole collar positions are surveyed by the site-based survey department or contract surveyors (utilising a differential GPS or conventional surveying techniques, with reference to a known base station) with a precision of less than 0.2m variability. All drill holes at Red Lake Operations have been surveyed for easting, northing and reduced level. Recent data is collected and stored in RLO Mine Grid. Topographic control was generated from aerial surveys and detailed Lidar surveys. |
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral |
The nominal drill spacing for Exploration drilling is 22m x 42m or wider and for Resource Definition is 11m x 21m.This spacing includes data that has been verified from previous exploration activities on the project. Data spacing and distribution is considered sufficient for establishing geological continuity and grade variability appropriate for classifying a Mineral Resource. |

| Resource and Ore Reserve estimation procedure(s) and classifications applied. Whether sample compositing has been applied. |
Sample compositing was not applied due to the often-narrow mineralised zones. |
|
| Orientation of data in relation to geological structure |
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
Mineralized zones in the Red Lake-Campbell deposit are distinguished first by spatial orientation relative to structural corridors and second by the style of mineralization. It is common for mineralized zones to have multiple styles of mineralization within the same host lithology. There are four types of mineralization in Red Lake-Campbell Deposit; 1) Vein Style Gold Mineralization, 2) Vein and Sulphide Style Gold Mineralization, 3) Disseminated Sulphide Style Mineralization locally referred to as replacement mineralization 4) Free Gold Mineralization Style The relationship between the drilling orientation and the orientation of key mineralised structures at Red Lake is not considered to have introduced a sampling bias and is not considered to be material. Resource Definition and Exploration drilling is typically planned to intersect mineralised domains in an orientation that does not introduce sample bias. A small number of holes are drilled at sub-optimal orientations to test for alternate geological interpretations. |
| Sample security | The measures taken to ensure sample security. |
Chain of custody protocols to ensure the security of samples are followed. Prior to submission samples are retained on site and access to the samples is restricted. Collected samples are dropped off at the respective commercial laboratories in North Western Ontario. Access into the laboratory is restricted and movements of personnel and the samples are tracked under supervision of the laboratory staff. During some drill campaigns some samples are collected directly from site by the commercial laboratory. While various laboratories have been used, the chain of custody and sample security protocolshaveremained similar. |
| Audits or reviews | The results of any audits or reviews of sampling techniques and data. |
Internal and External audits have been conducted in the past at Red Lake Operations. |

|---|---|---|---|
| Criteria | Explanation | Commentary | |
| The earliest known exploration on the Cochenour–Willans property was in 1925. Cochenour–Willans Gold Mines Ltd. was incorporated in 1936 and production began in 1939 at a rate of 136–181 t/d. Operations ran for 32 years, from 1939–1971. It was acquired by Goldcorp in 2008. Aside from the Red Lake gold mines and Cochenour mine, Evolution also holds past producing operations that include the HG Young, Abino, McMarmac, Gold Eagle Mine, and McKenzie Red Lake mines. In 2021, Evolution acquired Battle North Gold Corporation and the Bateman Project (previously the Phoenix project under Rubicon Minerals Corporation) on the McFinley peninsula including all associated mineral claims, surface/mining rights, a processing mill and Mineral Resources associated withthe project. |
|||
| Geology | Deposit type, geological setting and style of mineralisation. |
The mineralization within the Red Lake Operations can be classified as an Archean greenstone belt-hosted gold deposit. Red Lake Operations is hosted in the Red Lake greenstone belt within the Uchi Domain on the southern margin of the North Caribou Terrane of the Superior Province, Canada. Red Lake Operations is underlain mainly by tholeiitic basalt and locally by komatiitic basalt of the Balmer Assemblage. The mine sequence also includes felsic, peridotitic and other mafic to lamprophyric intrusive rocks of various younger ages. Both Red Lake- Campbell and Cochenour deposits are hosted within significantly folded and sheared portions of the Balmer assemblage. Shear zones act as primary hydrothermal fluid corridors and host significant portions of the gold mineralization in the area. Other significant mineralized structures occur within lower-strain areas of the stratigraphy, usually associated with brittle conjugate fracture systems in close proximity to lithological boundaries possessing high competency contrasts. Gold mineralization is hosted in a variety of rock types within the Red Lake Greenstone belt, although the majority of the productive zones occur as vein systems accompanying sulphide replacement within sheared mafic to komatiitic basalts of the Balmer Assemblage. Gold bearing zones in the Red Lake-Campbell and Cochenour deposit are distinguished first by spatial orientation relative to structural corridors and second by the style of mineralization. It is common for zones to have multiple styles of mineralization within the same host lithology. There are four styles of mineralization common in the Red Lake-Campbell and Cochenour deposit; Vein style, Vein and Sulphide style, Disseminated Sulphide (Replacement) style and free gold style. At the Bateman project gold is characterised by two distinct mineralisation styles; Vein hosted mineralisation and Sulfide Replacement mineralisation. Mineralisation is generally hosted in mafic units but limited mineralisation is also observed in felsic intrusions and ultramafic rock types. |

| Drill hole Information |
A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drillholes: o easting and northing of the drillhole collar o elevation or RL of the drillhole collar o dip and azimuth of the hole o downhole length and interception depth o hole length. |
Refer to the drill hole information table in the Appendix of this report. |
|
| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually material and should be stated. Where aggregate intercepts incorporate short lengths of high-grade results and longer lengths of low-grade results, the procedure used for such aggregation should be stated and some |
For results reporting: A minimum grade truncation of 2.74gpt standard is followed; no maximum grade truncation standard is applied. Where aggregate intercepts incorporate short lengths of high-grade and longer lengths of low-grade results, a weighted average of the values is applied to report the entire aggregate intercept. A short length high-grade intercept is then highlighted as an including value if result is >3 times the grade of the entire aggregate intercept in which it is incorporated. Intercept length weighted average techniques, minimum grade truncations and cut-off grades have been used in this report. If a hole has NSA values (ie gxm is less then 4 or 4g/t x m) the interval has been removed from the hole, if the entire hole has NSA, the hole is noted in the table in the appendix with an NSA value for g/t. |

| Logging | Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. Whether logging is qualitative or quantitative in nature. Core (or costean, channel etc.) photography. The total length and percentage of the relevant intersections logged. |
All diamond core is logged for regolith, lithology, veining, alteration, mineralisation and structure. Structural measurements of specific features are taken through oriented zones. All logging is quantitative where possible and qualitative elsewhere. A photograph is taken of every core tray (wet). |
|
| Sub-sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. If non-core, whether riffled, 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 field duplicate/second-half sampling. Whether sample sizes are appropriate to the grain size of the material being sampled. |
All diamond core that was half-core sampled was cut longitudinally with an automated core saw. Sample preparation was conducted by ALS Global, commencing with sorting, checking and drying at less than 110°C to prevent sulphide breakdown. Samples are jaw crushed to a nominal -6mm particle size. The entire crushed sample is then pulverized to 90% passing 75μm, using a bowl or ring-mill pulveriser. 300g Pulp subsamples are then taken with an aluminium scoop and stored in labelled pulp packets. Grind checks are performed at both the crushing stage (3mm) and pulverising stage (75μm), requiring 90% of material to pass through the relevant size to ensure consistent sample preparation. |
|
| 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 (i.e. lack of bias) and precision have been established. |
A 40-50g fire assay charge is used with a lead flux, dissolved in the furnace. The prill is totally digested in HCl and HNO3 acids before Atomic Absorption Spectroscopy (AAS) determination for gold analysis. This method ensures total gold is reported appropriately. No geophysical tools were used to determine any element concentrations Certified Reference Materials (CRMs) are inserted into the sample sequence randomly at a rate of 1 per 20 composite samples to ensure correct calibration. Any values outside of 3 standard deviations are scrutinised and re-assayed with a new CRM if the failure is deemed genuine. Blanks are inserted into the sample sequence at a rate of 1 per 20 composite samples. Failures above 0.2g/t are scrutinised, and re- assayed if required. New pulps are prepared if failures remain. All sample QAQC results are assessed by geologists to ensure the appropriate level of accuracy and precision when the results have been returned from the laboratory. |
|
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. The use of twinned holes. Documentation of primary data, data entry procedures, data verification and data storage (physical and electronic) protocols. Discuss any adjustment to assay data |
All significant intersections are verified by the project geologist and senior geologist during the drill hole validation process. Half core and sample pulps are retained at Mungari if further verification is required. The twinning of holes is not a common practice undertaken at Mungari. The face sample and drill hole data with the mill reconciliation data is of sufficient density to validate neighbouring samples. Data which is inconsistent with the known geology undergoes further verification to ensure its quality. All sample and assay information is stored utilising the acQuire database |

| Location of data points | Accuracy and quality of surveys used to locate drillholes (collar and downhole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Specification of the grid system used. Quality and adequacy of topographic control. |
All collars for underground drilling are located in the local mine grid by a mine surveyor using a laser theodolite. Mine Surveyors update control points underground as mine development continues. All drillhole collars are surveyed with locating two control points as required for precision of instrumentation. |
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. Whether sample compositing has been applied. |
The nominal drill spacing for Exploration drilling is 80m x 80m or wider and for Resource Definition is 40m x 40m or in some areas 20m x 20m. This spacing includes data that has been verified from previous exploration activities on the project. Data spacing and distribution is considered sufficient for establishing geological continuity and grade variability appropriate for classifying a Mineral Resource. Sample compositing was not applied due to the often-narrow mineralised zones. Compositing downhole within each estimation domain using a variable length compositing technique to a maximum length of one metre. The target composite length aligns with the dominant sample length of the raw sample data. |
| Orientation of data in relation to geological structure |
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
All drilling both underground and surface is oriented as close as practical to perpendicular to the target structures. The orientation of all in-mine target structures is well known and drill holes are only designed where meaningful intercept angles can be achieved. No sampling bias is considered to have been introduced by the drilling orientation. |
| Sample security | The measures taken to ensure sample security. |
Prior to submission samples are retained on site and access to the samples is restricted. Collected samples are dropped off at the respective commercial laboratories in Kalgoorlie. The laboratories are contained within a secured/fenced compound. Access into the laboratory is restricted and movements of personnel and the samples are tracked under supervision of the laboratory staff. |
| Audits or reviews | The results of any audits or reviews of sampling techniques and data. |
A Lab audit with ALS Global in Kalgoorlie was completed on the 1st of September 2021. No actions were issued as a result of the audit. |

The Kundana camp is situated within the Norseman-Wiluna Greenstone Belt, in an area dominated by the Zuleika Shear Zone, which separates the Coolgardie domain from the Ora Banda domain. The Zuleika Shear Zone in the Kundana area comprises multiple anastomosing shears the most important of which are the K2, the K2A and Strzelecki Shears. Raleigh mineralisation is hosted on the Strzelecki Structure. Strzelecki mineralisation consists of very narrow, very high-grade mineralisation on a laminated vein hosted in the camp-scale Strzelecki Shear which abuts a differentiated mafic intrusive, the Powder Sill Gabbro against intermediate volcanoclastic rocks (Black Flag Group). A thin ‘skin’ of volcanogenic lithic siltstone-sandstone lies between the gabbro and the Strzelecki shear. Being bound by an intrusive contact on one side and a sheared contact on the other, the thickness of the sedimentary package is highly variable from absent to about forty metres true width. The Hornet-Rubicon-Pegasus mineralisation consists primarily of high-grade laminated vein hosted gold on the K2 plane of the Zuleika shear with additional mineralisation on associated lower order structures. The Falcon target is a related mineralised zone in the hangingwall to Pegasus and between the two main Zuleika structures, the K2 and Strzelecki structures. |

Sampling of Au mineralisation at the Cue JV was undertaken using diamond core and aircore (AC) chips (surface). All drill samples were logged prior to sampling. Diamond drill core was sampled to lithological, alteration and mineralisation related contacts. AC sampling was conducted in 2m composite intervals downhole. Sampling was carried out according to Evolution protocols and QAQC procedures. All drill-hole collars were surveyed for initial drilling and picked up after drilling using a handheld GPS. The sampling and assaying methods are appropriate for the orogenic mineralised system and are representative for the mineralisation style. The sampling and assaying suitability was validated using Evolution’s QAQC protocol and no instruments or tools requiring calibration were used as part of the sampling process. Diamond drill-core sample intervals were based on geology to ensure a representative sample, with lengths ranging from 0.3m to 1.2m. Surface diamond drilling was half core sampled. One metre AC samples are laid out in rows of 20 on the ground and composite 2m samples were collected by scoop sampling the one metre piles to produce a 2-3kg composite sample which was sent to the Genalysis laboratory in Maddington, Perth for analysis. Sample condition data is recorded (wet, damp or dry) in the database. Generally, recovery is 80-100% but occasionally down to 30% on rare occasions when ground water pressure is very high. All diamond core and AC chip samples were dried, crushed and pulverised (total preparation) to produce a 50g charge for fire assay of Au. A suite of additional multi elements are determined using four-acid digest with ICP/MS and/or an ICP/AES finish for some selected intervals for pathfinder and lithostratigraphic use. These intervals are selected at the geologist’s discretion. |
| Drilling techniques | Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. 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.). |
Diamond holes from surface were wireline PQ (85mm diameter), HQ (63.5mm diameter) and some NQ (45.1mm diameter) holes. All diamond core from surface core was orientated using the Reflex ACT III bottom of hole orientation tool. The diamond drilling program reported here was undertaken by West Core Drilling Pty Ltd utilising a LF90D drill rig. The aircore drilling program was undertaken Ausdrill Ltd with a 3-inch drill pipe and blade (76mm) or hammer (76mm) using a custom built Lake Crawler drill rig and a KL150 track mounted aircore rig. |
| Drill sample recovery | 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 fine/coarse material. |
All diamond core was orientated and measured during processing and the recovery of individual core runs recorded. The core was reconstructed into continuous runs on a cradle for orientation marking. Hole depths were checked against driller’s core blocks. Inconsistencies between the logging and the driller’s depth measurement blocks are investigated. Diamond core samples are considered dry. The sample recovery and condition is recorded every metre. Generally, recovery is 98-100% but in weathered material occasionally down to 30% on rare occasions when ground is very broken. AC drill samples are dry until ground water is intersected. The sample size and condition (wet, damp, dry) is recorded every metre. Generally, recovery is 80-100% but occasionally down to 30% on rare occasions when ground water pressure is very high. The cyclone and sample buckets are routinely cleaned to reduce the likelihood of cross sample contamination. |

|---|---|---|
| Criteria | Explanation | Commentary |
| Logging | Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. Whether logging is qualitative or quantitative in nature. Core (or costean, channel etc.) photography. The total length and percentage of the relevant intersections logged. |
Diamond core has been geologically logged to the level of detail required for a Mineral Resource estimation. RQD measurements and geotechnical logging were taken from diamond core and recorded. All logging is both qualitative and quantitative in nature recording features such as structural data, sample recovery, lithology, mineralogy, alteration, mineralisation types, vein density/type, oxidation state, weathering, colour etc. All holes are photographed wet. Structural measurements are taken from core using a Kenometer instrument. All diamond and AC holes were logged in entirety from collar to end of hole. Drill logs are loaded directly into the acQuire database by the geologist. Drill core is cut on site by an automated Almonte core saw and half core is analysed. |
| Sub-sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. If non-core, whether riffled, 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 field duplicate/second-half sampling. Whether sample sizes are appropriate to the grain size of the material being sampled. |
Diamond core was drilled from surface and was half core sampled and the remaining half was retained. Aircore samples were collected as 2m composites for all drill holes in the current program using a scoop methodology. Sample preparation of diamond and AC samples was undertaken by external laboratories according to the sample preparation and assaying protocol established to maximise the representation of orogenic style gold mineralisation. The laboratories performance was monitored as part of Evolution’s QAQC procedure. Laboratory inspections are routinely undertaken to monitor the laboratories compliance sampling and sample preparation protocol. The sample and size (1.5kg to 4kg) relative to the particle size (>90% passing 75um) of the material sampled is a commonly utilised practice for effective sample representation for orogenic gold deposits. Quality control procedures adopted to maximise sample representation for all sub-sampling stages include the collection of duplicates (~1 in30) and the insertion of certified reference material (CRM) as assay standards (1 in 50) and the insertion of blank samples at appropriate intervals for early-stage exploration programs. High, medium and low grade gold CRM are used. Blank material is routinely submitted for assay and is inserted into each mineralised zone where possible. The quality control performance was monitored as part of Evolution’s QAQC procedure. Individual samples weigh less than 5kg to ensure total preparation at the laboratory pulverization stage. The sample size is deemed appropriate for the grain size of the material being sampled. Samples are sent to the Genalysis – Intertek laboratory in Maddington. Samples are pulverized to 85% passing -75um and two metre composite samples are analysed using a 50g fire assay with ICP-MS (inductively coupled plasma - mass spectrometry) finish gold analysis (0.005ppm detection limit). Individual one metre gold samples are analysed using a 50g fire assay with ICP-MS finish for gold. The pulp and bulk residue are retained at the lab until further notice. Duplicate samples are inserted in visually mineralised zones. A comparison of the duplicate sample vs. the primary sample assay result was undertaken as part of Evolution’s QAQC protocol. It is considered that all sub-sampling and lab preparations are consistent with other laboratories in Australia and are satisfactory for the intended purpose. The sample sizes are considered appropriate and in line with industry standards. |
| 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. |
The sampling preparation and assaying protocol used for this program was developed to ensure the quality and suitability of the assaying and laboratory procedures relative to the mineralisation types. Fire assay is designed to measure the total gold within a sample. Fire assay has been confirmed as a suitable technique for orogenic type mineralisation. It has been widely used in early stage exploration programs of this nature in the Cue region. In aircore drilling all samples through the cover-basement contact and into the Archaean regolith are analysed as 2m composites. Analysis is by 50g fire assay with ICP-MS finish for gold. Multi-element analysis is undertaken on all end of hole samples. On all samples, analysis is undertaken by Intertek-Genalysis (a |

registered laboratory), with 50g fire assay with ICP-MS finish undertaken for gold. In diamond drilling samples are analysed through potential gold mineralised zones. No geophysical tools or other remote sensing instruments were utilised for reporting or interpretation of gold mineralisation. Internal certified laboratory QAQC is undertaken including check samples, blanks and internal standards. Quality control samples were routinely inserted into the sampling sequence. The intent of the procedure for reviewing the performance of certified standard reference material is to examine for any erroneous results (a result outside of the expected statistically derived tolerance limits) and to validate if required; the acceptable levels of accuracy and precision for all stages of the sampling and analytical process. Typically, batches which fail quality control checks are re-analysed. This methodology is considered appropriate for gold mineralisation at the explorationphase. |
||
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. The use of twinned holes. Documentation of primary data, data entry procedures, data verification and data storage (physical and electronic) protocols. Discuss any adjustment to assay data |
Independent internal or external verification of significant intercepts is not routinely completed. The quality control / quality assurance (QAQC) process ensures the intercepts are representative for the orogenic gold systems. Half core and sample pulps are retained for when further verification is required. Data which is inconsistent with the known geology undergoes further verification to ensure its quality using multi-element data. All sample and assay information is stored utilising the acQuire database software system. Data undergoes QAQC validation prior to being accepted and loaded into the database. Assay results are merged when received electronically from the laboratory. The geologist reviews the database checking for the correct merging of results and that all data has been received and entered. Any adjustments to this data are recorded permanently in the database. Digital records of assay files are stored electronically. No adjustments or calibrations have been made to the final assay data reported by the laboratory. |
|
| Location of data points | Accuracy and quality of surveys used to locate drillholes (collar and downhole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Specification of the grid system used. Quality and adequacy of topographic control. |
All surface drill holes for this program have been surveyed for easting, northing and reduced level using handheld GPS with accuracy to 4 m. After a period of time, these are also picked up using a contract surveyor and a DGPS Downhole surveys were conducted at 30 m intervals downhole using a Reflex Ez-Gyro North Seeker Recent survey data at surface is collected and stored in MGA 94 Zone 50. Topographic control was generated from lidar and GPS. |
|
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. Whether sample compositing has been applied. |
Variable drill hole spacings are used to adequately test targets and are determined from geochemical, geophysical and geological data together with historical drilling information. Regional aircore drill hole traverse spacing is variable from 100m to 400m between lines and 50m to 100m along lines. Diamond drill holes are spaced at variable intervals based on geological interpretation. The drilling in this program has been designed to collect geological information from covered and undrilled areas. The holes are located to test for mineralisation, geology and structures based on interpretation of geophysics and mapping as well as below previous anomalous drilling results. No mineral resources or ore reserves have been estimated based on the exploration data and information generated on the tenements that are subject to the Musgrave – Evolution joint venture agreement Aircore samples were collected as 2m composites for all drill holes in the current program, unless EOH occurred on an odd number depth, using a scoop methodology from one metre sample piles. One metre individual samples are submitted for analysis where anomalous composite assays above 100ppb gold exist using a scoop methodology from one metre sample piles. Composite sampling is undertaken using a stainless-steel scoop (trowel) |

||
| Orientation of data in relation to geological structure |
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
Drilling is designed to cross the mineralisation as close to perpendicular as possible. Most drill holes are designed at a dip of approximately -55 to -60 degrees. The true width of drill intersections in fresh rock is not known at this time but gold dispersion mineralisation in the Archaean saprolite from aircore drilling is interpreted to be dominantly flat lying. There is no apparent bias in any of the drilling orientations used. The relationship between the drilling orientation and the orientation of key mineralised structures intersected in this early stage exploration is not considered to have introduced a sampling bias and is not considered to be material. |
| Sample security | The measures taken to ensure sample security. |
Chain of custody is managed by internal staff. Drill samples are stored on site and transported by a licenced reputable transport company (Toll road haulage) to a registered laboratory in Perth (Genalysis-Intertek at Maddington). When at the laboratory samples are stored in a locked yard before being processed and tracked through preparation and analysis (Lab-Trak system). The laboratories are contained within a secured/fenced compound. Access into the laboratory is restricted and movements of personnel and the samples are tracked under supervision of the laboratory staff. |
| Audits or reviews | The results of any audits or reviews of sampling techniques and data. |
All Diamond and AC QAQC data is monitored, and assays are reviewed internally to ensure the robustness and integrity of sampling and analysis methods. Field sampling techniques are set out in a field procedure which is reviewed atleast annually. |

| Geology | Deposit type, geological setting and style of mineralisation. |
Geology comprises typical Archaean Yilgarn greenstone belt lithologies and granitic intrusives. Two main styles of mineralisation are present, typical orogenic Yilgarn Archaean lode gold and volcanic massive sulphide (VMS) base metal and gold mineralisation within the Eelya Felsic Complex (northern tenure). |
| Drill hole Information | A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drillholes: o easting and northing of the drillhole collar o elevation or RL of the drillhole collar o dip and azimuth of the hole o downhole length and interception depth o hole length. |
All assay and collar information are tabulated in Appendix 1 of this report. Diamond: Calculation: Cut off grade of 0.5 g/t Au with a minimum ore composite length of 0.3m. The maximum consecutive waste (below 0.5 g/t) cannot exceed 2m however there is no limit to included waste. Significant intercepts are over 1 g/t Au average weighted grade and over 1 gram meter (length x weighted grade). Aircore: Calculation: Cut off grade of 0.1 g/t Au with a minimum ore composite length of 1m. The maximum consecutive waste (below 0.1 g/t) cannot exceed 2m however there is no limit to included waste. Significant intercepts are over 0.1 g/t Au average weighted grade and over 1 gram meter (length x weighted grade). |
| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually material and should be stated. Where aggregate intercepts incorporate short lengths of high-grade results and longer lengths of low-grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. The assumptions used for any reporting of metal equivalent values should be clearly stated. |
All significant new drill hole assay data of a material nature are reported in this release. No cut-off has been applied to any sampling. All intervals have been length weighted. All significant new drill hole assay data are reported in this release. No cut- off has been applied to any sampling. No metal equivalent values are used. |
| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. If it is not known and only the downhole lengths are reported, there should be a clear statement to this effect (e.g. _‘downhole length, true width not known’) _ |
This drill program consists of early-stage exploration targets with only an early stage understanding of structural orientations hosting mineralised intervals. Estimated True Widths are supplied wherever possible. |
| Diagrams | Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported. These should include, but not be limited to a plan view of drill hole. |
Drill hole location diagrams and representative sections of reported exploration results are provided either below or in the body of this report. |
