HIGHLIGHTS

Group Total Recordable Injury Frequency (TRIF) at 31 March 2020 declined to 7.2 (31 Dec 2019: 8.4) reflecting a continued trend of improving safety performance. Evolution's MSCI ESG rating was upgraded to 'A' from 'BBB', highlighting the Company's achievements in Sustainability performance.

Group gold production for the March 2020 quarter was 165,502 ounces (Dec qtr: 170,890oz) at an AISC of A$991/oz (Dec qtr: A$1,069/oz). Using the average AUD:USD exchange rate for the quarter of 0.6584, Group AISC equated to US$652/oz - ranking Evolution as one of the lowest cost gold producers in the world.

As at 31 March 2020, Evolution had cash in the bank of A$168.9 million and bank debt of A$570.0 million post draw down of the Red Lake facility on 31 March 2020 to fund the acquisition. By the date of this report on 23 April 2020 the cash balance and liquidity had increased to approximately A$240.0 million and A$600.0 million respectively.

Evolution delivered mine operating cash flow and net mine cash flow of A$257.4 million and A$159.7 million respectively (Dec qtr: A$233.1M; A$144.4M). Mine capital expenditure increased to A$97.7 million (Sep qtr: A$88.7M).

Standout operational performances for the quarter:

  • Mungari produced 32,721oz at an AISC of A$1,099/oz generating record net mine cash flow of A$31.9 million
  • Cracow produced 22,227oz at an AISC of A$1,150/oz generating record net mine cash flow of A$27.6 million
  • Ernest Henry produced 20,261oz at an AISC of A$(188)/oz generating net mine cash flow of A$59.6 million

rigs operating. Initial results are particularly pleasing at Cochenour where the best extensional hole intersected 6.60m (4.88m etw) grading 16.97g/t Au and the best resource definition hole intersected 3.30m (2.67 etw) grading 11.40g/t Au.

FY20 Group production, excluding Red Lake, is expected to be around 725,000 ounces at an AISC at the top end of guidance of A$990 per ounce. Should current spot metal prices be maintained during the June quarter, net cash flow is expected to be A$90 - 95 million higher4 but AISC would be negatively impacted by ~A$20 - 25/oz due to higher royalties and lower by-product credits. The majority of the higher production in the June quarter is expected to come from Mt Rawdon accessing higher grade ore in the open pit and Mt Carlton achieving first production from the higher-grade underground mine.

COVID-19 UPDATE

Evolution continues to actively respond to the ongoing COVID-19 virus currently impacting people and businesses globally. The health and safety of every person working at Evolution, their families and our communities remains paramount during this time.

To date there has been no material impact on Evolution's operations from the COVID-19 virus.

No Evolution employee or contractor has tested positive to COVID-19. Evolution continues to work closely with regulators and industry groups to ensure all our operations are complying with agreed protocols and all changing requirements.

Evolution is operating under protocols developed to minimise risks to our people and communities and ensure we can safely produce gold during this challenging period. These plans include activation of our crisis management protocols, suspending international travel, restricting domestic travel, suspending activities across most of the Company's greenfields exploration projects, enacting strict social distancing protocols including reducing face- to-face interactions, increasing flexible working arrangements, ensuring best practice health management is maintained at all times and regular COVID-19 communication with the entire workforce.

We have also been actively engaging with our communities to share our COVID-19 approach and offer support. Examples of community assistance include providing educational materials for local school children who are learning remotely, donating hampers to nurses in local hospitals, donating PPE and hand sanitisers to hospitals and emergency

services providers, offering temporary employment to community members who have lost their jobs, and providing iPads to a local aged care facility.

Additional site specific health and safety initiatives introduced by our operations include:

  • Extending rosters to reduce movement of people
  • Relocation of interstate employees
  • Introducing flexible working arrangements with people working from home where possible
  • Hiring additional vehicles and charter flights to ensure social distancing is maintained while travelling to site and during site activities
  • Floor markings 1.5 metres apart in pre-start areas to ensure social distancing
  • Reduced number of contractors permitted on site to perform mill shutdowns and extending shutdowns to perform tasks in compliance with required protocols
  • Introducing occupancy limits in offices and meeting rooms
  • Additional paramedics hired for the duration of the pandemic to ensure at least two paramedics are on site per roster
  • Daily temperature testing and screening of all personnel on site
  • Daily COVID-19 briefings to employees

OPERATIONS

Cowal, New South Wales (100%)

Mungari, Western Australia (100%)

Cowal produced 60,554oz of gold at an AISC of A$1,031/oz (Dec qtr: 65,080/oz, AISC A$898/oz). The planned lower production reflected the continued treatment of low grade stockpile material which was partially upgraded through ore-sorting.

Mine operating cash flow for the quarter was A$89.0 million (Dec qtr: A$95.9M). Net mine cash flow was A$34.5 million, post sustaining capital of A$3.6 million and major capital of A$51.0 million. Major projects investment included a continuation of Stage H stripping, the completion of the water pipeline twinning, the continuation of the Integrated Waste Landform (IWL) tailings facility construction and the underground Pre-Feasibility Study (PFS).

Total ore processed of 2.0Mt was lower than the December quarter due to both planned and unplanned shutdowns resulting in lower mill utilisation. Throughput is expected to increase back to the 9.0Mtpa run rate in the June 2020 quarter.

The combination of recent rains and increased pumping capacity through the completion of the pipeline twinning work have eased immediate water security issues. Work continues to further reduce the reliance on fresh groundwater offtake through accessing subsurface saline water sources.

GRE46 is Cowal's major project which provides significant production and mine life growth for the asset. The underground mine PFS is progressing to plan with an EPCM contractor mobilised during the quarter for initial design work. Underground drilling continues to upgrade resource classification and grow the 2.5Moz Mineral Resource. The maiden Ore Reserve is on track to be released in the December 2020 half year.

As Cowal progresses multiple projects, major capital for the year is expected to be A$165.0 - A$175.0 million. The higher investment is related to timing or new projects approved during the year comprising; Stage H development; water security infrastructure; and the underground mine PFS.

Mungari produced 32,721oz of gold at a significantly lower AISC A$1,099/oz (Dec qtr: 32,751oz, AISC A$1,344/oz).

Mine operating cash flow for the quarter was a record A$37.2 million (Dec qtr: A$30.4M). Net mine cash flow was also a record A$31.9 million (Dec qtr: A$24.8M) post sustaining and major capital investment of A$5.3 million.

The record net mine cash flow reflects a continued impressive turnaround as the operation consistently delivers to its operating plan. Mungari experienced strong margin expansion during the quarter driven by increased grade, lower sustaining capital and a higher gold price.

The Frog's Leg underground produced a consistent ore feed of 111kt at an increased grade of 3.62g/t gold (Dec qtr: 116kt at 3.27g/t gold). Total development of 389 metres was in line with operating plan.

Development to access the Boomer high grade vein is 90 metres from breaking through to the first ore position. Detailed drilling completed during the quarter informed design of the optimal access point for commencement of ore development. Vein access is expected to occur late in the June 2020 quarter.

White Foil open pit total material movement was 1,512kt, with ore mined at 563kt grading at 2.05g/t gold. Ore was sourced from both Stage 3a and 3b.

A major milestone was reached with Cutters Ridge open pit mining commencing during the quarter.

A total of 471kt of ore was processed at an average grade of 2.39g/t gold. Plant throughput was above plan but at a slightly lower rate than the December quarter as capital works commenced to achieve a sustainable 2.0Mtpa processing rate.

Mt Rawdon, Queensland (100%)

Mt Carlton produced 13,306oz of payable gold comprising of 11,672oz contained in 12,757 dry metric tonnes (dmt) of gold concentrate and 1,634oz in gold doré (Dec qtr: 9,787oz production; 9,710oz in concentrate; 77oz gold doré). AISC decreased to A$1,417/oz (Dec qtr: A$2,182/oz).

Mine operating cash flow was A$20.1 million (Dec qtr: A$2.7 million). Net mine cash flow was negative A$3.0 million post sustaining and major capital of A$23.2 million predominantly related to developing the new underground mine and capital development in the open pit (Dec qtr: A$22.7M).

Mill throughput exceeded plan with a total of 220kt of ore at 2.81g/t gold treated (Dec qtr: 229.2kt; 2.09g/t). Recoveries averaged 82.7%.

Underground development has reached the orebody three months ahead of schedule and underground stoping will commence in the June 2020 quarter providing higher grade feed to the mill. Orebody intersections in development are broadly aligning with expectations from drilling and grade control drilling continues to infill the underground orebody to a 10 x 10m pattern.

The early delivery of the underground mine and accelerated open pit waste stripping will result in major capital for FY20 of A$65.0 - A$70.0 million. The higher capital spend this financial year is related to timing of these projects which would have been invested in FY21.

Mt Rawdon produced 16,434oz of gold at an AISC of A$1,357/oz (Dec qtr: 20,338oz; A$1,815/oz).

Mine operating cash flow was A$18.1 million (Dec qtr: A$13.9M). Net mine cash flow of A$9.1 million (Dec qtr: A$9.1M) was generated post sustaining and major capital investment of A$8.9 million.

Total material mined was in-line with plan as the western wall stabilisation project continued in the March quarter.

A total of 833kt of ore was processed at an average grade of 0.70g/t gold (Dec qtr: 832kt at 0.86 g/t). Plant recovery was 87.9% and plant utilisation was 96.2%.

Mt Rawdon is on track to deliver significantly higher production and lower AISC in the June 2020 quarter with recommencement of mining higher grade ore in the south-western end of the pit.

Ernest Henry, Queensland

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

Evolution's interest in Ernest Henry delivered 20,261oz of gold and 4,470t of copper at an AISC of negative A$(188)/oz (Dec qtr: 23,080oz Au and 5,355t Cu at A$(526)/oz). Production in the quarter was negatively impacted by an unplanned breakdown in the ball mill which has been repaired. With excess processing capacity available, the operation is planning to make up for some of the March shortfall in the June quarter.

Ore mined was 1,755kt at an average grade of 0.60g/t gold and 1.10% copper. Underground lateral development was 2,234m, which includes 1,675m of operating development, 189m of capital development and 370m of rehab development. Ore processed was 1,496kt at an average grade of 0.60g/t gold and 1.09% copper. Gold recovery of 72.9% and copper recovery of 95.3% was achieved with mill utilisation at 79.4%.

Cash operating costs (C1) was negative A$(510)/oz after accounting for copper and silver by-product credits (Dec qtr: A$(925)/oz). Cash operating costs (C1) included by-product credits of A$(1,812)/oz.

Copper sales in the quarter were 4,470t at an average copper price of A$8,117/t.

Operating mine cash flow for the quarter was A$61.3 million representing the gold (A$55.2 million) and by-product sales of copper (A$36.3 million) and silver (A$0.4 million), net of Evolution's contribution to operating costs of A$30.6 million. Ernest Henry contributed a net mine cash flow of A$59.6 million, post sustaining capital of A$1.7 million.

Drilling below the 1200mRL is proceeding to plan with the development of a third platform currently underway. Initial drilling results have indicated mineralisation as expected which provided confidence to move to the next stage in the program. Over 18,000m of drilling is planned for CY2020.

Regarding COVID-19, a significant volume of work has been completed to ensure the sustainability of the Ernest Henry operation. A number of measures have been implemented specifically in relation to hygiene, cleaning and social distancing. To date, no significant impacts have been noted on the Ernest Henry operation.

Red Lake, Ontario (100%)

(Acquisition completed 31 March 2020)

Under the 'locked box' agreement with Newmont since 1 January 2020, Evolution will receive A$18.8 million in April 2020 from Red Lake's net cash generation in the March 2020 quarter. The mine produced and sold 37,895 and 42,141 ounces respectively in the March quarter.

Red Lake's June 2020 quarter production is expected to be around 25,000 ounces at an AISC of A$2,100 - A$2,3001 per ounce as the operation focuses on implementing the interim and transformation plans. Sustaining and major capital are expected to be A$5.0 - A$7.0 million and A$15.0 - A$17.0 million respectively. Exploration investment is expected to be A$3.0 - A$4.0 million.

Since the Red Lake acquisition was announced on 26 November 2019, all of Evolution's executive team, in addition to many other senior leaders and technical experts, have spent a considerable amount of time on site to commence planning the turnaround strategy and to ensure a smooth integration into the Evolution portfolio.

Key observations include: a high level of confidence in the ability to substantially grow mineral inventory; confirmation of the belief that fixed and variable costs can be significantly reduced; very positive engagement with the workforce who acknowledge change is required to secure the long term future of the operation; and validation of the scale of the turnaround opportunity.

An interim plan is now being executed at Red Lake as part of the delivery of a longer-term operational transformation with key objectives of:

  • Improving and maintaining the safety culture
  • Reducing AISC to below US$1,000 per ounce
  • Increasing production to above 200,000 ounces per annum

In order to recapitalise the asset and materially reduce the cost base of the operation, Evolution has committed to a significant investment in capital development and exploration over the next three years.

On 1 April 2020, immediately post completion of the acquisition, the Evolution Leadership team commenced 'virtual' town hall meetings to welcome the Red Lake team into the Evolution business. A new site leadership structure was announced and implemented which reduced leadership roles by 40%. Restructuring of the broader workforce will continue in the June 2020 quarter.

Evolution has made good progress to date in several key areas including:

  • Underground development rates increased to 755 metres in March. Development is expected to average 850 - 900 metres per month in the June 2020 quarter as the operation ramps up towards sustained development rates of over 1,000 metres per month from the September 2020 quarter onwards. Development in non- core areas has been stopped
  • Decommissioning of redundant underground mobile equipment
  • Commenced procurement process for underground mobile equipment to increase capacity and efficiencies. Delivery of the equipment is expected by the end of FY21.
  • Commencement of decommissioning the #1 shaft. Decommissioning of the Campbell shaft is scheduled for the March 2021 quarter
  • Refurbishment of the Campbell mill to improve reliability is underway and expected to be completed in the September 2020 quarter
  • Four diamond drills have commenced near mine resource definition and extensional drilling with a plan to increase this number to eight over the next 12 months

A discovery update is provided in the Exploration section of this report.

FINANCIALS

Evolution ended quarter with cash at bank of A$168.9 million. Group cash flow improved by 33% to A$111.5 million prior to paying dividends of A$119.3 million in March and costs associated with the Red Lake transaction. The completion of the Red Lake acquisition resulted in the drawdown of A$570.0 million of syndicated debt.

Net mine cash flow for the March 2020 quarter totalled A$159.7 million, exceeding the December 2019 quarter (A$144.4M) primarily due to favourable metal prices and record quarterly net mine cash flows at Mungari and Cracow.

Mungari generated a record net mine cash flow of A$31.9 million (Dec qtr: A$24.8M). This record builds on the positive momentum at the site over the last three quarters while achieving a consistent operating performance and a sustained improvement in mill throughput rates

Cracow also generated record net mine cash flow of A$27.6 million for the quarter (Dec qtr: A$16.0m) following further increases in plant throughput due to sustained improvements in crusher and mill utilisation as well as reduced capital spend at the site.

Cowal generated net mine cash flow of A$34.5 million (Dec qtr: A$51.9M) after investing A$53.7 million.

Ernest Henry and Mt Rawdon's net mine cash flows were in line with the December quarter at A$59.6 million, and A$9.1 million respectively (Dec qtr: A$62.7M; and A$9.0M) while Mt Carlton's net mine cash flow was negative A$3.0 million (due to the investment on developing the new underground mine) but was better than the December quarter (negative A$20.0M) due to improved costs, higher sales volumes and a higher gold price.

During the March quarter, Evolution sold 167,374oz of gold at an average gold price of A2,366/oz (Dec qtr: 173,408oz at A$2,091/oz). Deliveries into the hedge book totalled 25,000oz at an average price of A$1,786/oz with the remaining 142,374oz of gold was delivered on spot markets at an average price of A$2,468/oz.

  • 17m (13.6m etw) grading 4.56g/t from 1,267m (1535DD544C)
  • 28m (22.4m etw) grading 2.36g/t from 1,140m (1535DD453G)
  • 5m (4m etw) grading 9.19g/t from 1,222m (1535DD453G)
  1. including 1m (0.8m etw) grading 38.7g/t from 1,225m

Surface drilling during the June quarter will focus on mineral resource extensions down plunge of known shoots.

The underground drilling program targeted mineralisation in the lava and Dalwhinne/volcaniclastics below the Warraga Decline with the aim of converting resources from inferred to indicated classification. Significant intercepts included:

  • 5m (4m etw) grading 28.99g/t from 40m (GRUD0120)
  • 12m (9.6m etw) grading 10.80g/t from 409m (GRUD0109)
  • 23m (18.4m etw) grading 5.12g/t from 252m (GRUD0116)
  • 34m (27.2m etw) grading 3.07g/t from 548m (GRUD0116)
  • 22m (17.6m etw) grading 4.3g/t from 246m (GRUD0108)

Underground drilling continues from the eastern drill platforms targeting inferred mineral resource blocks in order to convert to indicated classification in the northern lava and the Dalwhinnie areas.

EXPLORATION

Mungari, Western Australia (100%)

A total of 12,930m of drilling was completed across three targets at Mungari during the quarter (Figure 6). Of this drilling, 45 surface diamond drill holes were completed at the Boomer prospect for 11,232m.

Boomer

Extensional and infill drill holes at Boomer, located 300m west of Frog's Leg development, continues to intercept a narrow, folded, laminated quartz vein, predominantly dipping 65° towards the south-west, with a shallow southeast plunge. Step-out drilling discovered a new lower lode, also folded and laminated, with a similar dip and plunge orientation. The vein contained visible gold and base metal sulphides. Best intercepts for the quarter include:

  • 1.22m (1.03m etw) grading 119.95g/t Au from 146.3m (EVDD0110)
  • 0.24 (0.22m etw) grading 102.88g/t Au from 215.8m (EVDD0082A)
  • 0.38m (0.33m etw) grading 37.24g/t Au from 197.7m (EVDD0072)

Assays are pending for seven holes. The Boomer access drive is 185m from the Frogs Leg decline and is expected to intersect the Boomer vein late in the June 2020 quarter.

Picante Trend

Drilling continued along the Picante Trend approximately 1.5km north of the planned Castle Hill pit. Two diamond holes (443m in total) targeted a small high grade mineralised shoot now called Muy Picante. The holes intercepted mineralisation on the sheared contact between the tonalite and ultramafic and assisted with understanding controls on mineralisation and grade trends for estimation. Best intercepts include:

  • 4.00m (3.87m etw) at 1.65g/t Au from 108 m (PICD030)
  • 1.00m (0.97m etw) at 31.20g/t Au from 140 m (PICD031)
  • 9.00 (8.70m etw) at 1.96g/t Au from 163 m (PICD031)

Exploration will continue along the 5km strike extent of the Picante Trend in FY21.

Australian Greenfields Exploration

At the Cue Project (EVN earning 75% from Musgrave Minerals Ltd, ASX:MGV) an initial diamond drilling program was completed with two holes drilled for 574m during the quarter. A large regional aircore drilling program is ongoing over Lake Austin, with 138 holes drilled for 14,382m. It is anticipated the program will be completed early in the June 2020 quarter.

At the nearby Murchison Joint Venture (EVN earning 80% from Enterprise Metals Limited, AZX:EML) an aircore drilling program completed 77 holes (6034m) before it was suspended due to COVID-19 restrictions.

Exploration programs were suspended on the Drummond Project (EVN earning 80% from Andromeda Metals Limited, ASX:ADN) and at Connors Arc (EVN 100%) during the quarter also as a result of COVID-19.

Explanation

  • 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, handheldXRF instruments, etc). These examples should not be taken as limiting the broad meaning ofsampling.
  • 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 thePublic Report.
  • In cases where 'industry standard' work has been completed this wouldbe relatively simple (e.g. 'reverse circulation drilling was used to obtain 1m samples from which 3 kg was pulverised to produce a 30 g chargefor fire assay'). In other cases, more explanation may be required, such as where there is coarse gold that has inherent sampling problems, or unusual commodities/mineralisationtypes (e.g. submarine nodules).
  • 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 whatmethod, etc.).
  • Method of recording and assessing core and chip sample recoveries andresults assessed.
  • Measures taken to maximise sample recovery and ensure representativenature of the samples.
  • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain offine/coarse material.

Commentary

  • 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 0.15 to 0.9m. 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.
  • Drilling on site is conducted using diamond drill rigs, the core is extracted using a standard tube and core diameter is either BQTK (40.7mm) or NQ (47.6mm) in size,
  • All exploration drill core is orientated using the Tru-Core device.
  • Percentage of drill core recovery is not recorded at this time on site. All core is oriented and marked up at 1-foot intervals, intervals are compared to drillers depth.

Commentary

All logging is both qualitative and quantitative in nature

recording features such as structural data, lithology,

mineralogy, alteration, mineralisation types, vein density, colour

etc. All holes are photographed wet.

All diamond holes were logged in entirely from collar to end of

hole.

All drill core once logged is digitally photographed. The

photographs capture all data presented on the core.

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.

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.

    o hole length.
  • In reporting Exploration Results,

  • Where aggregate intercepts incorporate short lengths of high-graderesults and longer lengths of low-graderesults, the procedure used for such aggregation should be stated and some typical examples of such aggregationsshould be shown in detail.
  • The assumptions used for any reporting of metal equivalent valuesshould be clearly stated.
  • These relationships are particularly important in the reporting of ExplorationResults.

Commentary

  • 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.
  • Refer to the drill hole information table in the Appendix of this report.
  • 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.
  • Composite lengths and grade as well as internal significant values are reported in Appendix.
  • No metal equivalent values are used.
  • At Red Lake Operations where reliable estimated true widths can be calculated these have been included along with down hole measurements.

  • There are two assay analysis methods used for Boomer diamond samples with visible gold have four 40g charges extracted from the parent pulp sample bag and fire assayed with the average used for final reporting. This is to manage the variability in assay grades due to the nuggetty gold. Boomer vein intercepts without visible gold have the standard 1 x 40g fire assay as described above.
  • Measures taken to ensure sample representation include the collection of field duplicates during RC drilling at a frequency rate of 5%. Duplicate samples for both RC chips and diamond core are collected during the sample preparation pulverisation stage. 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.
  • The sampling preparation and assaying protocol used at Mungari 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 extensively used throughout the Goldfields region. Screen fire assay and LeachWELL / bottle roll analysis techniques have also been used to validate the fire assay techniques.
  • The technique utilised a 30g, 40g or 50g sample charge with a lead flux, which is decomposed in a furnace with the prill being totally digested by 2 acids (HCI and HN03) before the gold content is determined by an AAS machine.
  • No geophysical tools or other remote sensing instruments were utilised for reporting or interpretation of gold mineralisation.
  • Quality control samples were routinely inserted into the sampling sequence and were also inserted 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.
  • 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 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 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
