OVERVIEW
Evolution achieved a significant improvement in safety performance during FY20 with Group Total Recordable Injury Frequency (TRIF) declining by 18% to 6.8 at 30 June 2020 (30 June 2019: 8.3). This improvement is more significant given the TRIF was 9.3 at the end of September 2019. A Safety Stop was enacted across all of Evolution’s sites during the quarter to bring renewed focus to our safety performance throughout the entire business. Pleasingly there were zero recordable injuries in the month of June 2020.
COVID-19 continues to be proactively managed with no material impact to operations. Annual Sustainability audits were conducted in the June quarter at each operating and exploration site resulting in no material adverse findings.
As outlined in today’s ASX release entitled “Cowal Maiden Underground Ore Reserve Supports Mine Development,” Cowal declared a Maiden Underground Ore Reserve of 9.96Mt grading 2.51g/t Au for 804koz and Mineral Resources of 36.51Mt grading 2.48g/t Au for 2.9Moz – an increase of 410koz. An application for regulatory approval is expected to be submitted early in the December 2020 quarter and feasibility work is being completed in parallel to allow accelerated mine development.
Red Lake performed better than plan in its first quarter under Evolution ownership, producing 27,428oz at an AISC of A$1,943/oz. This beat guidance of around 25,000oz at A$2,100 – A$2,300 per ounce. A workforce restructure took place in June, reducing the number of full-time employees by 114 to 740 people. Underground development rates continue to ramp up with 1,036 metres achieved in the month of June 2020. Evolution’s transformation plan is ahead of expectations to restore production to above 200,000 ounces per annum at an AISC of less than US$1,000 per ounce.
Group gold production for the June 2020 quarter was 218,104 ounces (Mar qtr: 165,502oz) at an AISC of A$1,088/oz (Mar qtr: A$991/oz) which includes the higher cost ounces at Red Lake. Using the average AUD:USD exchange rate for the quarter of 0.6571, Group AISC equated to US$715/oz which places Evolution at the bottom of the cost curve amongst major and mid-tier global gold producers.
As at 30 June 2020, Evolution had cash in the bank of A$373.6 million and bank debt of A$570.0 million. This is an increase in cash of $204.7 million for the quarter.
Evolution delivered record mine operating cash flow and net mine cash flow of A$352 million and A$224 million respectively (Dec qtr: A$257M; A$160M).
Mine capital investment for the quarter was A$112 million (Mar qtr: A$98M).
Standout operational performances for the quarter:
-
Cowal produced 60,594oz at an AISC of A$941/oz generating net mine cash flow of A$59.3 million
-
Ernest Henry produced 28,183oz at an AISC of A$(617)/oz generating record net mine cash flow of A$68.3 million
-
Mungari produced 37,178oz at an AISC of A$1,089/oz generating record net mine cash flow of A$39.8 million
-
Mt Rawdon produced 25,982oz at an AISC of A$1,305/oz generating record net mine cash flow of A$32.3 million
Drilling at Red Lake’s Cochenour deposit returned strong results with the best extensional hole intersecting 6.09m (4.67m etw) grading 18.86 g/t Au along strike of the Gold Eagle Corridor. The best resource definition hole at Cochenour intersected 4.64m (4.01m etw) grading 22.10g/t Au.
Several significant intersections at the Cowal Underground continued to provide robust infill results including: 94m (75.2m etw) grading 5.0g/t Au and 33m (26.4m etw) grading 19.0g/t Au.
Infill drilling at Mungari’s Boomer deposit confirmed geological and grade continuity of the narrow folded laminated vein in a small area where it is well developed. Best intersections returned during the quarter included 0.79m (0.67m etw) grading 133.8g/t Au and 0.40m (0.33m etw) grading 98.6g/t Au.
On 4 June 2020 Evolution announced an agreement to divest the Cracow gold mine to Aeris Resources Limited (ASX:AIS) for a total consideration of up to A$125 million. The consideration consists of A$60 million cash which was received on completion, A$15 million cash to be received on 30 June 2022, and up to A$50 million contingent consideration. The sale was successfully completed on 1 July 2020.
FY20 Group production from Australian operations was 719,035 ounces at an AISC of A$1,008 per ounce. This was in line with the revised guidance issued on 19 June 2020 of 715,000 at an AISC of A$990 per ounce before the impact of the higher gold price and lower copper price.
FY20 mine operating cash flow and net mine cash flow was a record A$1,121 million and A$736 million respectively.
FY21 guidance and a three-year outlook for Group production, AISC and capital will be provided with the release of Evolution’s FY20 Financial Results on 13 August 2020.

Cowal, New South Wales (100%)
Cowal produced 60,594oz of gold at an AISC of A$941/oz (Mar qtr: 60,554/oz, AISC A$1,031/oz). Mine operating cash flow for the quarter was A$117.4 million (Mar qtr: A$89.0M). Net mine cash flow was A$59.3 million (Mar qtr: A$34.5M) post sustaining capital of A$3.3 million and major capital of A$54.8 million. Major projects investment included continuation of Stage H stripping, construction of the Integrated Waste Landform (IWL) tailings facility and the underground PreFeasibility Study (PFS).
Stockpiles continued to be processed during the quarter with processed grade partially upgraded through ore sorting. Gold recovery improved to 83.2% driven by increased efficiencies in the elution and regeneration circuits.
Total ore processed was 2.1Mt delivering a 7% increase for the full year to 8.5Mt. Improved throughput was a result of plant upgrades, strategic maintenance planning and improvements, and increased plant utilisation.
The successful completion of the dual water pipeline and increased dam capacity on site has significantly improved Cowal’s water security position. The identification of subsurface saline water sources is continuing with the objective of reducing reliance on fresh sources.
Cowal declared a Maiden Underground Ore Reserve of 804koz and an increased underground Mineral Resource to 2.9Moz. An application for regulatory approval of an underground mine development is expected to be submitted early in the December 2020 quarter. In parallel, a Feasibility Study focussing on detailed design and optimisation of capital and operating costs will be completed.
Full year mine operating cash flow was A$416.8 million. Net mine cashflow was A$235.6 million.
FY21 Cowal production is expected to be between 205,000 – 230,000 ounces due to the planned processing of lower grade stockpiles following depletion of medium grade stockpiles during FY20. This is part of the transition to Stage H ore which remains on schedule for the second half of FY21.

OPERATIONS
Red Lake, Ontario (100%)
(Acquisition completed 31 March 2020)
Red Lake made good progress in the June quarter towards Evolution’s transformation plan to restore the operation’s production to above 200,000 ounces per annum at an AISC of less than US$1,000 per ounce.
Red Lake produced 27,428oz of gold at an AISC of A$1,943/oz in its first quarter under Evolution ownership (Guidance: 25,000 ounces at an AISC of A$2,100 – A$2,300/oz).
Mine operating cash flow for the quarter was A$30.8 million. Sustaining capital of A$6.6 million and major capital of A$14.3 million resulted in mine cash flow of A$9.9 million prior to restructuring costs of A$12.8 million.
The underground mine produced ore feed of 131kt at an average grade of 8.0g/t gold. Ore was sourced from Upper and Lower Red Lake, Campbell and Cochenour. Underground development rates increased in each month to 1,036 metres in June (refer chart). This is materially better than the 850 – 900 metres per month guided in the March 2020 quarterly report. Increases have been achieved through the restructuring of roles and responsibilities, focusing on specific areas in close proximity to each other, and increasing the utilisation of the mining fleet. Underground development is planned to continue to increase to above 1,200 metres per month during the December 2020 half year.
Ore processed for the June quarter was 124kt at an average grade of 8.1g/t gold. This was split between the Campbell mill (63kt at 6.9g/t) and the Red Lake mill (61kt at 9.4g/t). The Campbell mill completed a major shut down during the quarter which focused on improving reliability. This was well ahead of the previously guided scheduled completion in the September quarter and since the shut down the plant has been operating at 98.4% availability. The Red Lake mill has ceased operating and will be used for campaign processing when excess ore is available.

FINANCIALS
Evolution’s cash balance increased by A$204.7 million during the quarter to A$373.6 million. Bank debt as at 30 June 2020 was A$570.0 million equating to net bank debt of A$196.4 million. Group cash flow improved by 69% to A$187.9 million after allowing for A$16.2 million of restructuring costs at Red Lake and Mt Carlton.
Net mine cash flow for the June 2020 quarter was a record A$224.5 million primarily due to higher metal prices. Record quarterly net mine cash flows were achieved at Ernest Henry, Mungari, Mt Rawdon, and Cracow. This contributed to an annual record net mine cash flow of A$736.0 million.
For the second consecutive quarter, Mungari generated a record net mine cash flow of A$39.8 million (Mar qtr: A$31.9M). This achievement is the result of consistent operating performance over the course of the year including sustained improvement in mill throughput rates.
Mt Rawdon generated record net mine cash flow of A$32.3 million (Mar qtr: A$9.1M) due to the planned return to mining of high-grade material from the southwest corner of the pit. The resulting higher production was supported by the gold price and stable costs, translating to the strong cash generation in the quarter.
Cracow also achieved record net mine cash flow of A$27.8 million (Mar qtr: A$27.6m) following tight cost discipline combined with sustained plant throughput levels.
Ernest Henry produced record net mine cash flow of A$68.3 million for the quarter (Mar qtr: A$61.3M) driven by increased production and elevated gold prices. Cowal generated net mine cash flow of A$59.3 million (Mar qtr: A$34.5M) after investing A$58.1 million. Red Lake generated net mine cash flows of A$9.9 million after investment of A$20.9 million but before restructuring costs of A$12.8 million.
During the June quarter, Evolution sold 218,685oz of gold at an average gold price of A$2,500/oz (Mar qtr: 167,374oz at A$2,366/oz). Deliveries into the hedge book were as planned and totalled 25,000oz at an average price of A$1,794/oz with the remaining 166,339oz of gold delivered on spot markets at an average price of A$2,590/oz. A further 26,808oz from Red Lake was delivered on spot markets at an average price of C$2,381/oz.

EXPLORATION
Exploration highlights
Red Lake
- Resource definition and extensional drilling continued with five underground drill rigs. Results at Cochenour continue to be encouraging with the best step-out hole intersecting 6.09m (4.67m etw) grading 18.86 g/t Au. This result confirms extension of the Gold Eagle Corridor along strike to the north. Results of definition drilling continue to be in line with expectations and will support resource classification upgrades at Cochenour, Twin Otter and the Deep Sulphides Zone. The best resource definition infill hole intersected 4.64m (4.01m etw) grading 22.10g/t Au at Cochenour. Work also focused on building a new geology and resource model as a basis for releasing an updated Mineral Resource
Cowal
- Drilling at the Cowal Underground was focused on resource conversion and extending mineralisation beyond underground resource outlines. Several significant intersections continued to provide robust infill results including: 94m (75.2m etw) grading 5.0g/t Au and 33m (26.4m etw) grading 19.0g/t Au demonstrating geological and grade continuity of the orebody. The geological and resource model was updated 30 April 2020 as part of completion of the Pre-Feasibility Study and Maiden Underground Ore Reserve declaration.
Mungari
- The underground access drive from the Frog’s Leg decline intersected the Boomer vein on 30 May 2020. Further infill drilling completed at Boomer continued to intercept a narrow folded laminated vein with visible gold. The best intersections returned were 0.79m (0.67m etw) grading 133.8g/t Au and 0.40m (0.33m etw) grading 98.6g/t Au. RC drilling designed to test a one kilometre long extension of the Boomer structure to the north has commenced
Mt Carlton
- Initial encouraging assay results have been received for several holes at the Crush Creek project (EVN earning 100%) located 30 kilometres southeast of Mt Carlton. Drilling has confirmed as well as extended and filled in zones on the Delta prospect. Several excellent intersections including 31.7m (27.5m etw) grading 5.68g/t Au and 4.0m (4.0m) grading 25.89g/t Au illustrate the potential for high-grade mineralisation in narrow, structurally controlled ore shoots
Total drilling of 23,550m (resource definition) and 40,587m (discovery) was completed during the quarter. Evolution’s exploration tenement holding interests in Australia and Canada now stands at 8,570 km[2] .
Red Lake, Ontario (100%)
During the quarter, underground diamond drilling campaigns continued at Cochenour and Lower Red Lake. A total of 71 diamond drill holes (15,566m) were drilled utilising five drill rigs. Work also focused on building a new geology and resource model as a basis for releasing an updated Mineral Resource estimate.

Cochenour
Two diamond rigs were operating at Cochenour during the June quarter. Forty-two drill holes totalling 6,948m were drilled. Sixteen holes were collared from the 3735 Exploration drift (Figure 2). These holes were targeting future production horizons and step outs from these mining areas to test if mineralisation is closed off along strike. Twenty-six holes were collared from the 4485 Exploration drift (Figure 3). Holes continue to intercept lenses of mineralised iron formation as well as the brecciated quartz-actinolite veins and basalt that comprise the Gold Eagle Shear corridor.
Significant infill intercepts from the 3735 exploration drift confirmed grade continuity indicated by previous wider spaced drilling. Results include:
-
2.83m (2.45m etw) grading 20.03 g/t Au from 131.9m (C37224) - BIF (Infill)
-
5.91m (2.95m etw) grading 5.84 g/t Au from 98.2m (C37225) - BIF (Infill)

EXPLORATION
Infill drilling from the 4485 exploration drift has been successful at defining additional mineralisation.
Three longer step-out holes drilled from the same position in the 4485 drift targeted the extension of the Gold Eagle Corridor in an area known as the VOSS target. Hole C44187 intercepted a 4.7m wide zone grading 18.9g/t Au. Further drilling is designed to test around this initial intercept to understand potential for resource growth in this area which is situated beyond existing resource shapes.
Significant intercepts from the 4485 exploration drift are reported below with the best infill results illustrated in Figure 3.

• 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 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.

Core (or costean, channel etc.) photography. The total length and percentage of the relevant intersections logged. |
• 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. • 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. |
• 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 assayis designed tomeasure the totalgoldwithina |

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.

• 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 datareported by thelaboratory. |

| Criteria | Explanation | Commentary | ||
| Geology | •Deposit type, geological setting and style of mineralisation. |
• The mineralisation 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 mineralisation in the area. Other significant mineralised 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 mineralisation 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 mineralisation. It is common for zones to have multiple styles of mineralisation within the same host lithology. There are four styles of mineralisation common in the Red Lake-Campbell and Cochenour deposit; Vein style, Vein and Sulphide style, Disseminated Sulphide (Replacement) style and free gold style. |

| 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 typical examples of such aggregations should be shown in detail. •The assumptions used for any reporting of metal equivalent values should be clearly stated. |
• 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. |

| Relationship between mineralisation widths and intercept lengths |
•These relationships are particularly important in the reporting of Exploration Results. |
• At Red Lake Operations where reliable estimated true widths can be calculated these have been included along with down holemeasurements. |

applied to all holes. • Prior to 2018 drill core was halved with a diamond saw in 1 m intervals, irrespective of geological contacts. Since 2018 Sampling to lithological contacts has been implemented. Oxide material that was too soft and friable to be cut with a diamond saw was split with a chisel. Core was cut to preserve the bottom of hole orientation mark and the top half of core sent for analysis 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 ALS Orange. Sample preparation consisted of: • Drying in the oven at 105ºC; crushing in a jaw crusher; fine crushing in a Boyd crusher to 2-3mm; rotary splitting a 3kg assay sub-sample if the sample is too large for the LM5 mill; pulverising in the LM5 mill to nominal; 90% passing 75 µm; and a 50g fire assay charge was taken with an atomic absorption (AA) finish.

• No dedicated twinning drilling has been conducted for this drill program. • Cowal uses DataShed software system to maintain the database. Digital assay results are loaded directly into the database. The software performs verification checks including checking for missing sample numbers, matching sample numbers, changes in sampling codes, inconsistent “from-to” entries, and missing fields. Results are not entered into the database until the QA/QC Administrator approves of the results. A QA/QC report is completed for each drill hole and filed with the log, assay sheet, and other appropriate data. Only the Senior Project Geologist and Database Manager have administrator rights to the database. Others can use and sort the database but not save or delete data. |

• 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. |

| 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. |

• The Cowal gold deposits (E41, E42, E46, Galway and Regal) occur within the 40 km long by 15 km wide Ordovician Lake Cowal Volcanic Complex, east of the Gilmore Fault Zone within the eastern portion of the Lachlan Fold Belt. There is sparse outcrop across the Lake Cowal Volcanic Complex and, as a consequence, the regional geology has largely been defined by interpretation of regional aeromagnetic and exploration drilling programs. • The Lake Cowal Volcanic Complex contains potassium rich calc-alkaline to shoshonitic high level intrusive complexes, thick trachyandesitic volcanics, and volcaniclastic sediment piles. • The gold deposits at Cowal are structurally hosted, epithermal to mesothermal gold deposits occurring within and marginal to a 230m thick dioritic to gabbroic sill intruding trachy-andesitic volcaniclastic rocks and lavas. • The overall structure of the gold deposits is complex but in general consists of a faulted antiform that plunges shallowly to the north-northeast. The deposits are aligned along a north-south orientated corridor with bounding faults, the Booberoi Fault on the western side and the Reflector Fault on the eastern side (the Gold Corridor). |

• 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). |

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 unusual commodities/mineralisation types (e.g. submarine nodules). |
• Sampling of gold mineralisation at Mungari was undertaken using diamond core (surface) and reverse circulation (RC) drill chips. • All drill samples were logged prior to sampling. Diamond drill core was sampled to lithological, alteration and mineralisation related contacts, whilst RC samples were collected at 1m downhole intervals. Sampling was carried out according to Evolution 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 Evolution’s QAQC protocol and no instruments or tools requiring calibration were used as part of the sampling process. • RC drilling was sampled to obtain 1m samples using a static cone splitter from which 3 to 5 kg was crushed and pulverised to produce a 30g to 50g subsample for fire assay. Diamond drillcore sample intervals were based on geology to ensure a representative sample, with lengths ranging from 0.2 to 1.2m. Surface diamond drilling was half core sampled. All diamond core samples were dried, crushed and pulverised (total preparation) to produce a 30g to 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. |

• Most diamond core drilled from surface was half core sampled and the remaining half was retained. In the oxide zone, where cutting can wash away samples, some surface holes were full core sampled. • All RC samples were split by a cone or a riffle splitter and collected into a sequenced calico bag. Any wet samples that could not be riffle split were dried then riffle split. • Sample preparation of RC and diamond samples was undertaken by external laboratories according to the sample preparation and assaying protocol established to maximise the representation of the Mungari mineralisation. Laboratories performance was monitored as part of Evolution’s QAQC procedure. Laboratory inspections were undertaken to monitor the laboratories compliance to the Mungari sampling and sample preparation protocol. • The sample and size (2.5kg to 4kg) relative to the particle size (>85% passing 75um) of the material sampled is a commonly utilised practice for effective sample representation for gold deposits within the Eastern Goldfields of Western Australia. • 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. The quality control performance was monitored as part of Evolution’s QAQC procedure. • The sample preparation has been conducted by commercial laboratories. All samples are oven dried (between 85°C and 105°C), jaw crushed to nominal <3mm and if required split by a rotary splitter device to a maximum sample weight of 3.5kg as required. The primary sample is then pulverised in a one stage process, using a LM5 pulveriser, to a particle size of >85% passing 75um. Approximately 200g of the primary sample is extracted by spatula to a numbered paper pulp bag that is used for a 40g fire assay charge. The pulp is retained and the bulk residue is disposed of after two months. • There are two assay analysis methods used for Boomer diamond samples; samples with visible gold in the laminated quartz vein, have four 40g charges extracted from the parent pulp sample bag and fire assayed with the average used for final reporting.

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 arere-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 and entered. Any adjustments to this data are recorded permanently in the database.

•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. |
• Mineralisation at Boomer is hosted within a narrow, folded, laminated quartz vein, predominantly dipping 65° towards the south-west, with a shallow south-east plunge. The mineralised structure lies within a 35m wide shear zone dipping 70° west. Surface and underground drilling intersect the mineralisation at an angle to minimise bias. • The relationship between the drilling orientation and the orientation of key mineralised structures at Mungari 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 ore domains in an orientation that does not introduce sample bias. A small number of holes are drilled at sub-optimal orientations to testforalternate 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 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. 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 protocols haveremained similar. |
| Audits or reviews | •The results of any audits or reviews of sampling techniques and data. |
• The Mungari geology and drilling database was reviewed by acQuire in December 2015 and no material issues were identified. • Oscillating cone splitter has been in use for RC sampling at all prospects. Data collected has returned more consistent duplicate sample weights than a standard static cone splitter. |

| Criteria | Explanation | Commentary |
| 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 unusual commodities/mineralisation types (e.g. submarine nodules). |
• Sampling of Au-Ag mineralisation at the Crush Creek JV was undertaken using diamond core (surface). • 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 Evolution protocols and QAQC procedures which comply with industry best practice. All drill-hole collars were surveyed for initial drilling using a handheld GPS, and later surveyed using a differential GPS. • The sampling and assaying methods are appropriate for the epithermal style mineralised system targeted 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 drillcore sample intervals were based on geology to ensure a representative sample, with lengths ranging from 0.3m to 1m. Surface 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. Ag, As, Bi, Cd, Cu, Fe, Pb, S, Sb and Zn were also assayed in addition to Au assays using an aqua-regia digest with ICP/AES finish. 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. |
| Drilling techniques | •Drill type (eg 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) and HQ (63.5mm diameter) holes. • All diamond core from surface core was orientated using the digital Reflex Act lll bottom of hole orientation tool. |
| 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 into the drill-hole database. 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. Surface drilling recoveries were generally excellent. • Measures taken to maximise sample recovery include drilling using triple tube methodology, instructions to drillers to slow down drilling rates during key parts of drill holes or reducing the core run length in less competent ground. |

• Diamond core drilled from surface was half core sampled and the remaining half was retained. • Sample preparation of diamond samples was undertaken by external laboratories according to the sample preparation and assaying protocol established to maximise the representation of low-sulphidation epithermal style Au-Ag mineralisation. 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 epithermal gold deposits. • 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. 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. • The sample preparation has been conducted by commercial laboratories. All samples are oven dried (between 85°C and 105°C), jaw crushed to nominal <3mm and if required split by a riffle splitter device to a maximum sample weight of 3kg as required. The primary sample is then pulverised in a one stage process, using a LM5 pulveriser, to a particle size of >90% passing 75um. Approximately 200g 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 and bulk residue are retained at the lab until further notice. • Duplicate samples for diamond core are collected during the sample crushing 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. |

When higher grades (>20 g/t Au) are reported by the AAS machine, the quantity of gold in sample is then automatically determined using gravimetric methods. • 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. Batches which fail quality control checks are re-analysed. In addition, the laboratory is instructed to place barren quartz flushes in the sample sequence in areas of anticipated mineralisation.

| Geology | •Deposit type, geological setting and style of mineralisation. |
• Crush Creek mineralisation is located within the apex of Bowen basin volcanic stratigraphy which is also host to epithermal Au- Ag-Cu mineralisation at the nearby high-sulphidation epithermal deposits at Mt. Carlton, located ~30km NW of the Crush Creek JV Mineral Development License. • Local geology at Crush Creek comprises the late Carboniferous to early Permian Lizzie Creek Volcanics, consisting locally of andesitic and felsic derived volcaniclastic units intruded by a series of rhyolitic domes. Mineralisation at Delta is hosted along extensional structures in primary volcaniclastic breccias and sediments. Primary volcanic breccias are overprinted by a low- sulphidation Au-Ag epithermal event. Bonanza mineralisation at Delta is hosted by late narrow quartz-sulphide veins associated with this epithermal event. Mineralisation at BV7 is interpreted to be the same age as at Delta but is hosted on extensional structures developed within coherent felsic volcanic rocks. Mineralisation is associated with quartz vein development on these structures. |

• Refer to the drill hole information table in the Appendix of this report for significant assay results from Evolutions drilling to date at Delta. All mineralised intercepts above 5gram*metre (grade x down-hole width) are shown in the table. • Previous mineralised intercepts and drilling at Delta are not shown on plans and sections in the body of this report, or in the significant intercept table. This drilling was generally vertical with no down-hole surveys, drilled with predominantly open- hole methods and QAQC procedures outside of Evolutions protocols. Open-hole drilling can cause contamination in drill samples, particularly in a narrow high-grade gold environment. • There have been a number of previous operators who have drilled at the Delta and BV7 prospects.
