OVERVIEW

In March 2021 Evolution became a participant in the world’s largest corporate sustainability initiative, the United Nations Global Compact (UNGC), pledging to support its Ten Principles on human rights, labour, environment, and anti-corruption.

Group Total Recordable Injury Frequency (TRIF)[1] at 31 March was 8.6 (31 December: 7.9). There is a continued focus on improving safety performance and critical risk management. Mt Rawdon has now achieved 14 months recordable injury free.

COVID-19 continues to be proactively managed across all operations.

Group gold production for the March 2021 quarter was 161,316 ounces (Dec qtr: 180,305oz) at an AISC of A$1,268/oz (Dec qtr: A$1,166/oz). Using the average AUD:USD exchange rate for the quarter of 0.7730, Group AISC equated to US$980/oz which continues to place Evolution as one of the lowest cost producers amongst the major and mid-tier global gold companies.

The quarter was impacted by heavy rainfall at Mt Rawdon restricting access to higher grade ore in the open pit. All other operations performed broadly in line with plan.

A strong June quarter is expected. Group AISC guidance has been improved to A$1,190 – A$1,220 per ounce while production guidance has been narrowed to 695,000 – 710,000 ounces (original guidance 670,000 – 730,000 ounces at an AISC of A$1,240 – A$1,300 per ounce).

As at 31 March 2021, Evolution had cash in the bank of A$333.1 million and bank debt of A$500.0 million equating to net bank debt of A$166.9 million. The FY21 interim dividend of A$119.6 million (7 cents per share, fully franked, 16th consecutive dividend) was paid to shareholders during the quarter.

Evolution achieved mine operating cash flow and net mine cash flow of A$194.3 million and A$101.2 million respectively (Dec qtr: A$258.9M; A$170.5M). Mine capital investment for the quarter increased to A$93.1 million (Dec qtr: A$85.6M). The average realised gold price for the March quarter was A$2,227 per ounce (Dec qtr: A$2,416/oz).

Standout operational performances for the quarter:

  • Red Lake continued to ramp-up production producing a record under Evolution ownership of 35,810oz at an AISC of A$1,966/oz. Net mine cash flow was A$1.2 million post total capital of A$24.8 million.

  • Ernest Henry produced 22,408oz at a record low AISC of negative A$1,027/oz generating net mine cash flow of A$74.8 million

  • Cowal produced 51,823oz at an AISC of A$1,078/oz generating net mine cash flow of A$18.7 million post total capital of A$38.2 million

At Red Lake, Ore Reserves were estimated at 2.9 million ounces at an average grade of 6.9g/t gold, in accordance with the JORC Code. Approval was received for the development of a decline into the Upper Campbell area of the mine which hosts Ore Reserves of 1.85 million ounces at 7.4g/t gold. Construction of the box cut has progressed well and the mining contract to commence development of the decline is in final commercial negotiations.

On 15 March 2021 Evolution announced an agreement to acquire Battle North Gold Corporation (TSX: BNAU) for approximately C$343 million. This expands Evolution's footprint in the Red Lake region and is expected to create value by leveraging the infrastructure of both operations. The additional processing capacity from Battle North’s new Bateman mill will also accelerate Evolution's ability to achieve the long-term objective of producing in excess of 300,000 ounces of gold per year from the Red Lake. The Battle North shareholder vote to approve the acquisition is scheduled for 11 May 2021.

Resource definition and discovery drilling at Red Lake was ongoing with six underground drill rigs. Results of definition drilling will support resource classification upgrades at Cochenour, Deep Sulphides, Lower Campbell and the Twin Otter Zone. The best resource definition infill hole intersected 17.0m (16.0m etw) grading 8.7g/t gold from 116m (32L487) in Deep Sulphides.

The size of the Cowal underground continues to expand with Mineral Resources increasing to 3.0 million ounces and Ore Reserves increasing to 1.0 million ounces in the release of Evolution's Annual Mineral Resources and Ore Reserves Statement released on 17 February 2021. Total Mineral Resources and Ore Reserves at Cowal stand at 9.7 million ounces and 4.6 million ounces respectively. The Underground Feasibility Study is progressing well with the final outcome of the study on schedule for completion in the September 2021 quarter.

Bryan O’Hara, General Manager Investor Relations, will step down from his current role effective 30 June 2021 to pursue a career in funds management. Evolution thanks Bryan for his outstanding contribution to improving the Company’s reputation in the market for providing high quality and transparent information to all stakeholders. Evolution is pleased to advise that Martin Cummings has been appointed as Bryan’s replacement. Martin has extensive industry experience including the last seven years with Evolution in roles as General Manager Commercial, Treasury, and Group Supply which involved him leading banking, procurement and insurance relationships. Bryan will stay with the Company until 30 September 2021 to ensure a smooth transition.

OPERATIONS

Cowal, New South Wales (100%)

Cowal produced 51,823oz of gold at an AISC of A$1,078/oz (Dec qtr: 54,926oz, AISC A$958/oz). Mine operating cash flow for the quarter was A$56.9 million (Dec qtr: A$77.5 million). Net mine cash flow was A$18.7 million (Dec qtr: A$39.2 million) post sustaining capital of A$1.4 million and major capital of A$36.8 million. The site managed through the extraordinary 1-in-100-year weather event in March extremely well with only a minor impact to operations .

Major projects continued including the Stage H stripping and construction of the Integrated Waste Landform (IWL) tailings facility. The Galway decline successfully commenced during the quarter with underground diamond drilling expected to begin early in the June 2021 quarter. The Underground Feasibility Study remains on track for completion in the September 2021 quarter. Statutory approvals are progressing well. Evolution submitted a response to submissions during the quarter and a determination is expected in the coming months.

Ernest Henry, Queensland

(Economic interest; 100% gold and 30% copper production)[1]

Evolution’s interest in Ernest Henry delivered 22,408oz of gold and 4,596t of copper at a record low AISC of negative A$1,027/oz (Dec qtr: 24,473oz Au and 4,972t Cu at negative A$710/oz).

Operating mine cash flow for the quarter was A$77.3 million representing gold (A$49.7 million) and by-product sales of copper (A$55.2 million) and silver (A$0.7 million), net of Evolution’s contribution to operating costs of A$28.3 million. Ernest Henry generated a net mine cash flow for Evolution of A$74.8 million, post sustaining capital of A$2.4 million.

Ore mined was 1,520kt at an average grade of 0.62g/t gold and 1.09% copper.

OPERATIONS

Red Lake, Ontario (100%)

Mungari, Western Australia (100%)

Red Lake produced 35,810oz of gold at an AISC A$1,966/oz (Dec qtr: 33,709, AISC A$1,937/oz). Mine operating cash flow for the quarter was A$26.1 million (Dec qtr: A$34.2 million). Net mine cash flow was A$1.2 million (Dec qtr: A$10.3 million) post sustaining capital of A$13.4 million and major capital of A$11.4 million. Timing of sales was a factor in lower cash flow with around 3,000 ounces produced but not sold during the quarter.

Underground development of 2,872m (Dec qtr: 2,956m) was impacted by loss of water and seismic events in February. Development of 1,152m in the month of January reflects continued improvements in productivity over the past 12 months. Evolution's long-term development objective remains 1,200m per month.

The underground mine produced ore feed of 183kt at an average grade of 6.14g/t gold. Ore processed was 191kt at 6.34g/t gold. The Campbell mill achieved recoveries of 90.9% and a utilisation of 98.7% (Dec qtr: 92.2% and 97.0% respectively). An Evolution record of 56.2kt of ore was processed at Campbell mill in March. The Red Lake mill was successfully commissioned in February achieving recoveries of 93.9% and a utilisation of 83.2%.

Mungari produced 27,226oz of gold at an AISC A$1,561/oz (Dec qtr: 30,463oz, AISC A$1,402/oz).

Mine operating cash flow for the quarter was A$30.8 million (Dec qtr: A$38.2 million). Net mine cash flow was A$10.9 million (Dec qtr: A$22.7 million) post sustaining and major capital investment of A$19.9 million (Dec qtr: A$15.5M). Lower cash flow was mainly a result of planned capital expenditure on Tailings Storage Facility construction.

Plant throughput remained consistent at 498kt (Dec qtr: 493kt) and is on track to achieve 2.0Mt for the 12 months of FY21 which is well in excess of its 1.6Mtpa nameplate capacity.

Frog’s Leg underground production was ahead of plan with 128kt of ore mined at 3.07g/t gold (Sep qtr: 127kt at 3.15g/t Au). Total underground development was 636m.

Open pit total material mined was 1,878 (Dec qtr: 1,822kt). Open pit ore mined was 223kt at 1.22g/t gold (Dec qtr: 439kt at 1.37g/t). Total material movement is increasing as mining at Cutters Ridge ramps up. Ore mined reduced during the quarter as White Foil Stage 3 nears completion.

March quarter key milestones:

  • Ore Reserves estimated at 2.9 million ounces in accordance with JORC Code

The Castle Hill processing studies are progressing with results expected during the September 2021 quarter.

  • Campbell Young Dickenson (CYD) box cut construction commenced with decline development expected to commence in the September 2021 quarter

OPERATIONS

Mt Rawdon, Queensland (100%)

Mt Carlton, Queensland (100%)

Mt Rawdon produced 11,930oz of gold at an AISC of A$2,400/oz (Dec qtr: 24,306 oz; A$1,170/oz).

Mine operating cash flow was A$6.2 million (Sep qtr: A$29.9 million). Net mine cash flow of A$0.2 million (Dec qtr: A$24.2 million) was generated post sustaining and major capital investment of A$6.0 million.

Mt Rawdon celebrated 20 years of continuous operations on 16 February 2021. A significant milestone of 365 days without a recordable injury was achieved on 25 February 2021 and the operation has now been injury free for over 14 months.

Seasonal heavy rainfall during the March quarter resulted in restricted access to the lower parts of the pit which impacted material movement which was below plan.

Mt Carlton produced 12,117oz of payable gold (Dec qtr: 12,428oz) in 15,753 dry metric tonnes (dmt) of concentrate. AISC was A$2,090/oz (Dec qtr: A$2,214/oz).

Mine operating cash flow was negative A$3.0 million (Dec qtr: A$1.3 million). Net mine cash flow of negative A$4.6 million (Sep qtr: A$0.4 million) was realised post sustaining and major capital investment of A$1.6 million. Cash flows were adversely impacted by timing of shipments which will be realised in the June 2021 quarter.

Underground mining was focused on establishing a production front in the Western Feeder zone. Decline development commenced in the A39 silver deposit which will reach mineralisation during the June 2021 quarter. A39 hosts Ore Reserves of approximately 500,000 ounces of high-grade silver.

As a result of restricted pit access, ore processed of 855kt was predominantly sourced from stockpiles at an average grade of 0.51g/t gold (Dec qtr: 839kt at 1.00g/t Au). Plant recoveries decreased to 85.3% due to lower feed grade. Plant utilisation was 95.7% (Dec qtr: 89.8% and 95.7% respectively).

Production is expected to improve in the June 2021 quarter as access to higher grade ore in the open pit is regained.

EXPLORATION

Highlights

The Annual Mineral Resource and Ore Reserve Statement released on 17 February 2021 reinforced the exciting exploration upside at Red Lake and Cowal with estimated Mineral Resources of 11.1 million ounces and 9.7 million ounces respectively. Quality drilling targets continue to be prioritised at Red Lake and Cowal with the potential to further extend resources and deliver new discoveries from these large, highly prospective tenement holdings. The land position at Red Lake will almost double with the addition of the Bateman properties to the portfolio following completion of the Battle North Gold Corporation acquisition which is expected to occur in the June 2021 quarter. Extensions at Frog’s Leg have the potential to incrementally extend this high-grade production source for Mungari.

Total drilling of 14,341m (resource definition) and 22,414m (discovery) was completed during the quarter. Evolution’s exploration tenement holding interests in Australia and Canada now stand at 8,751 km[2] .

Red Lake, Ontario (100%)

Drilling continued with six underground and three surface rigs. Five rigs were deployed at lower Red Lake, Campbell and Cochenour focused on reserve conversion priorities which are anticipated to come into the production schedule over the next 12 to 24 months. Discovery utilised three surface diamond rigs to drill targets along the East Bay Trend, in the Western Stratigraphy and at the SR Zone (see locations in Figure 2). These areas were prioritised geologically for their potential to host new zones of high-grade mineralisation. The sixth underground rig continued drilling the Hangingwall Corridor where the geological architecture, permissive of hosting high grade mineralisation, has not been effectively tested.

Best results from the underground resource definition drilling are summarised below from Cochenour and Red Lake. A total of 55 diamond holes were completed for 13,055m of drilling (Figure 1).

Resource Definition

Cochenour

Infill drilling results (13 holes, 4,047m) from the Upper Main Zone (UMZ) and BIF zone are confirming continuity of grade within Inferred classification resources that are expected to upgrade to Indicated classification when the models are re-estimated in the December 2021 quarter. Best results are outlined below.

  • 7.25m (6.57m etw) grading 10.00g/t Au from 166.7m (C44219) – BIF/UMZ (Infill)

  • 3.99m (3.75m etw) grading 6.50g/t Au from 122m (C44223) – BIF/UMZ (Infill)  2.51m (2.40m etw) grading 30.80g/t Au from 111m (C44224) – BIF/UMZ (Infill)  4.11m (3.56m etw) grading 12.40g/t Au from 115.3m (C53892) – UMZ (Infill)

Step-out drilling at Lower Cochenour incrementally extended mineralisation below the base of the current Mineral Resource in the UMZ next to the Gold Eagle Shear. Highlights include:

  • 5.77m (4.42m etw) grading 6.00g/t Au from 155.4m (C53883) – UMZ (Extensional)

  • 7.63m (6.47m etw) grading 7.80g/t Au from 133.1m (C53884) – UMZ (Extensional)

Importantly, mineralisation remains open along strike and down dip. Two long step-out holes are planned in the June 2021 quarter to test depth potential for the resource extensions beyond the results reported in holes C53883 and C53884.

Red Lake

Results from infill drilling (34 holes totalling 7,586m) at Twin Otter, Deep Sulphides and the HGZ Footwall zones are outlined below. Several impressive widths and grades have been returned from a small lens approximately 100 metres in the footwall of the Deep Sulphide ore body which is a new zone with no history of previous mining.

  • 2.48m (2.15m etw) grading 11.50g/t Au from 251.3m (46L479) – Twin Otter

  • 4.00m (3.28m etw) grading 5.80g/t Au from 232m (46L478) – Twin Otter

  • 17.00m (15.97m etw) grading 8.70g/t Au from 116m (32L487) – Deep Sulphides

Discovery

One underground rig and three surface diamond rigs completed drilling on Discovery targets during the March quarter (Figures 1 and 2). The surface drill programs were designed to target important stratigraphic and structural positions between Campbell-Red Lake and Cochenour. The underground drill program continued to test prospective stratigraphy and structures in the Hangingwall Corridor outboard of the Kovala fault which is an important structure in the geological architecture influencing the geometry of the historically mined High Grade Zone. Hole D271538 returned a significant intercept (reported below) with follow-up drilling ongoing to test the extent and continuity of this zone.

Cowal

Development of the Galway decline commenced in late February and advanced 333 metres during the quarter. Early drilling positions were established for the underground rig which will commence drilling early in the June 2021 quarter. This next phase of underground drilling is designed to extend resources across the gap between Dalwhinnie and Regal along with upgrading Mineral Resource classification that will convert additional resources to reserves.

Infill and extensional drilling continued at GRE46 with eight surface diamond holes (3,238m). At Dalwhinnie, drilling extended and infilled the Mineral Resource within and beyond the main ore body. Results continue to expand the mineralisation footprint at Dalwhinnie which remains open down plunge and along strike. Significant intercepts included:

  • 4.0m (2.8m etw) grading 24.53g/t from 772m (1535DD575)

  • 25.0m (18.8m etw) grading 2.07g/t from 194m (1535DD578)

  • 15.0m (11.3m etw) grading 4.14g/t from 61m (1535DD578)

Surface drilling commenced on the Nikka target which is a continuation of the E42 mineralisation around the central fault beneath the pit. Results are pending.

Mungari, Western Australia (100%)

A total of 4,546m of drilling was completed during the quarter at the Frog’s Leg, Castle Hill and Harpers Lagoon project areas. Near mine resource definition drilling at Frog’s Leg targeted extensions below the extent of current development at the base of the Rocket ore body. Resource definition drilling was conducted to increase geological confidence in the Castle Hill resource. Regional exploration was also undertaken at the Harpers Lagoon prospect. Assay results for these programs are pending.

==> picture [319 x 359] intentionally omitted <==

Figure 4: Location map of Mungari resource definition and regional projects in the March 2021 quarter

Resource definition drilling was conducted at Frog's Leg with 18 diamond holes (1,550m) completed below the Rocket ore body. The purpose of the drilling was to close out the gap between deepest development in the mine and the next deepest drill hole which indicates the ore body is closed off. There is an opportunity to incrementally extend underground production at Frog’s Leg if this drilling confirms the ore body extends into this previously untested gap. Drilling intercepted the mineralised vein structure characteristic of the Rocket ore body. Visible gold has been identified in most intercepts which is an encouraging early outcome although mineralised true widths reflect the ore body narrowing. Assays are pending with results expected to be reported in the June 2021 quarter.

Mt Carlton - Crush Creek, Queensland (100%)

At Crush Creek a maiden Mineral Resource of 126,000oz gold was released in Evolution’s Annual Mineral Resources and Ore Reserves Statement. Drilling will recommence following the end of the Queensland wet season during the June 2021 quarter. The program is designed to continue building on the positive results reported in the December 2020 quarter from the Gamma and Delta prospects. A number of new targets have been developed during the wet season based on results received from soil geochemical sampling and mapping which were completed prior to completion of the last field season in December 2020.

Australian Greenfields Exploration

Diamond drilling commenced at the Cue Project (EVN earning 75% from Musgrave Minerals Ltd, ASX:MGV) in Western Australia with three holes completed for 1,142m. The holes are targeting bedrock origins of mineralisation underneath the five-kilometre-long gold-in-air core anomaly delineated in previously reported results from Lake Austin. Full results from the seven-hole diamond program are expected to be reported in the June 2021 quarter.

At the nearby Murchison Joint Venture (EVN earning 80% from Enterprise Metals Limited, ASX:ENT), preparations are underway to undertake a first phase of RC-diamond drilling in the June quarter.

Further information on all reported exploration results included in this report is provided in the Drill Hole Information Summary and JORC Code 2012 Table 1 presented in Appendix 2 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.

Data is reported to significant figures to reflect appropriate precision and may not sum precisely due to rounding. Mineral Resources are reported inclusive of Ore Reserves. UG denotes underground. 1Includes stockpiles 2 Ernest Henry Operation cut-off 0.9% CuEq 3 Red Lake cut-off is 3.3g/t Au except for Cochenour (3.0g/t Au) and HG Young (3.2g/t Au) deposits

4 Group Mineral Resources Competent Person (CP) Notes refer to 1. James Biggam; 2. Dean Fredericksen; 3. Brad Daddow; 4. Tim Murphy; 5. Ben Coutts; 6. Jessica Shiels (Glencore)

5The Mineral Resource for the Mt Carlton A39 underground deposit has been estimated using a AuEq (g/t) cut-off of 4.4g/t to enable quotation of this silver rich deposit as equivalent gold ounces.

The gold equivalent (AuEq) calculation accounts for silver recoveries determined from metallurgical test work and uses an assumed silver price of A$26/oz and gold price of A$2,000/oz as per the below equation.

AuEq=26/2,0000.8203silver grade (Silver price/Gold pricesilver recoverysilver grade). It is the Competent Persons opinion that the assigned cut-off criteria satisfies the JORC Code requirement that the reported Mineral Resource meets reasonable prospects of eventual economic extraction and that the silver present within the A39 deposit can be economically recovered.

This information is extracted from the ASX release entitled “Annual Mineral resource and Ore Reserve Statement” released to the ASX on 17 February 2021 and is available to view at www.evolutionmining.com.au. Full details of the Ernest Henry Mineral Resources and Ore Reserves are provided in the report entitled “Glencore Resources and Reserves as at 31 December 2020” released 3 February 2021 and available to view at www.glencore.com. Evolution Mining has an economic interest earning rights to 100% of the revenue from future gold production and 30% of future copper and silver produced from an agreed area, and 49% of future gold, copper and silver produced from the Ernest Henry Resource outside the agreed area. The Ernest Henry Resource is reported here on the basis of economic interest and not the entire mine resource. The above reported figures constitute 77% of the total Ernest Henry gold resource.

The Company confirms that it is not aware of any new information or data that materially affects the information included in the Reports and that all material assumptions and parameters underpinning the estimates in the Reports continue to apply and have not materially changed. The Company confirms that the form and context in which the Competent Persons’ findings are presented have not been materially modified from the original market announcements.

5The Ore Reserve for the Mt Carlton A39 underground deposit has been estimated using a AuEq (g/t) cut-off of 6.1g/t to enable quotation of this silver rich deposit as equivalent gold ounces

The gold equivalent (AuEq) calculation accounts for silver recoveries determined from metallurgical test work and uses an assumed silver price of A$20/oz and gold price of A$1,450/oz as per the below equation.

AuEq = 20/1,4500.8203silver grade (Silver price/Gold pricesilver recoverysilver grade). It is the Competent Persons opinion that the assigned cut-off criteria meets the minimum acceptable criteria to support economic extraction and that the silver present within the A39 deposit can be economically recovered.

This information is extracted from the ASX release entitled “Annual Mineral resource and Ore Reserve Statement” released to the ASX on 17 February 2021 and is available to view at www.evolutionmining.com.au. Full details of the Ernest Henry Mineral Resources and Ore Reserves are provided in the report entitled “Glencore Resources and Reserves as at 31 December 2020” released 3 February 2021 and available to view at www.glencore.com. Evolution Mining has an economic interest earning rights to 100% of the revenue from future gold production and 30% of future copper and silver produced from an agreed life of mine area, and 49% of future gold, copper and silver produced from the Ernest Henry Resource outside the agreed area. Ernest Henry Reserve is reported here on the basis of economic interest and not the entire mine reserve. The above reported figures constitute 86% of the total Ernest Henry gold reserve.

The Company confirms that it is not aware of any new information or data that materially affects the information included in the Reports and that all material assumptions and parameters underpinning the estimates in the Reports continue to apply and have not materially changed. The Company confirms that the form and context in which the Competent Persons’ findings are presented have not been materially modified from the original market announcements.

In cases where ‘industry standard’

would be relatively simple (e.g.
‘reverse circulation drilling was
used to obtain 1 m samples from

commodities/mineralisation types
(e.g. submarine nodules).

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.

 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.

Sampling to lithological contacts has been implemented. Oxide

to ensure no bias is introduced. RC samples were collected
directly from a splitter at the drill rig.

Sample preparation was conducted by SGS West Wyalong and

All drill hole collars were surveyed using high definition DGPS.
All drill holes were surveyed using a downhole survey camera.
The first survey reading was taken near the collar to determine
accurate set up and then at regular intervals downhole.

On completion of each angled drill hole, a down hole gyroscopic
(Gyro) survey was conducted. The Gyro tool was referenced to
the accurate surface surveyed position of each hole collar.

The Gyro results were entered into the drill hole database
without conversion or smoothing.

An aerial survey was flown during 2003 by AAM Hatch. This
digital data has been combined with surveyed drill hole collar
positions and other features (tracks, lake shoreline) to create a
digital terrain model (DTM). The survey was last updated in late
2014.

In 2004, Cowal implemented a new mine grid system with the
assistance of AAM Hatch. The current mine grid system covers
all areas within the ML and ELs at Cowal with six digits.

The exploration drillholes reported in this report are targeted to
test for continuity of mineralisation as interpreted from previous
drilling. It is not yet known whether this drilling is testing the full
extent of the mineralised geological zones. All drilling prior to
2018 is sampled at 1 m intervals down hole. Lithological based
sampling was implemented in 2018 with a maximum sample
length of 1m and a minimum sample length of 0.3m to avoid
sampling across geological boundaries.

Diamond holes were positioned to optimise intersection angles

however the extent of the vein package is currently unknown.

Drilling at Galway Regal is oriented perpendicular to the known
mineralised package.
Sample security
The measures taken to ensure
sample security.

Drill contractors are issued with drill instructions by an Evolution
geologist. The sheet provides drill hole names, details, sample
requirements, and depths for each drill hole. Drill hole sample
bags are pre-numbered. The drill holes are sampled by
Evolution personnel who prepare sample submission sheets.
The submission sheet is then emailed to the laboratory with a
unique submission number assigned. This then allows
individual drill holes to be tracked.

An SGS West Wyalong (SGS) representative collects the
samples from site twice daily, however, if samples are being
sent to another laboratory a local freight company is used to
collect the samples from site and deliver them to the laboratory.
Upon arrival, the laboratory sorts each crate and compares the
received samples with the supplied submission sheet. The
laboratory assigns a unique batch number and dispatches a
reconciliation sheet for each submission via email. The
reconciliation sheet is checked, and any issues addressed. The
new batch name and dispatch information is entered into the
tracking sheet. The laboratory processes each batch separately
and tracks all samples through the laboratory utilising the LIMS
system. Upon completion, the laboratory emails Standard
Industry Format (SIF) files with the results for each batch to
Evolution personnel.

The assay batch files are checked against the tracking
spreadsheet and processed. The drill plan is marked off
showing completed drill holes. Any sample or QA/QC issues
with the results are tracked and resolved with the laboratory.

Audits or reviews
The results of any audits or reviews
of sampling techniques and data.

QA/QC Audits of the Primary SGS West Wyalong Laboratory
are carried out on an approximately quarterly basis and for the
Umpire ASL Orange Laboratory approximately on a six-monthly
basis. Any issues are noted and agreed remedial actions
assigned and dated for completion.

Numerous internal audits of the database and systems have
been undertaken by site geologists and company technical
groups from North Ltd, Homestake, Barrick and Evolution.
External audits were conducted in 2003 by RMI and QCS Ltd.
and in 2011 and 2014 review and validation was conducted by
RPA. MiningOne conducted a review of the Cowal Database in
2016 as part of the peer review process for the Stage H
Feasibility Study. Recent audits have found no significant issues
with data management systems or data quality.

Significant intercepts have nominally been calculated based

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’)

Mineralisation within the drilling area is bounded by large
north-south trending structures, however it has strong
internally oblique structural controls. Drill holes are typically
oriented to optimise the angle of intercept at the target
location. All significant intercepts are reported as down hole
intervals unless labelled as Estimated True Widths (ETW).
Diagrams
Appropriate maps and sections (with
scales) and tabulations of intercepts
should be included for any significant
discovery being reported. These
