OPERATIONS
Group gold production for the March 2017 quarter was 202,926 ounces which was in line with guidance of approximately 200,000 ounces issued in the ASX announcement on 22 March 2017 entitled “Ernest Henry Site Visit and Operating Update” (Dec qtr: 217,812oz). Average C1 cash cost was A$599/oz (Dec qtr: A$585/oz). AISC[1] declined 7% to a record low A$840/oz (Dec qtr: A$900/oz). Using the average AUD:USD exchange rate for the quarter of 0.7584, Evolution’s Group C1 cash cost equated to US$454/oz and Group AISC to US$637/oz – ranking Evolution as one of the lowest cost gold producers in the world.
In the March 2017 quarter Evolution delivered operating mine cash flow of A$166.5 million and net mine cash flow, post all sustaining and major capital, of A$110.7 million (Dec qtr: operating cash flow A$170.3 million; net mine cash flow A$102.1 million). Evolution made debt repayments totalling A$40.0 million and a dividend payment of A$27.4 million net of the Dividend Reinvestment Plan during the quarter.
As at 31 March 2017, gross debt outstanding under the Senior Secured Syndicated Revolving and Term Facility was A$560.0 million. Net debt was reduced to A$541.2 million.
Ernest Henry was a standout in its first full quarter of attributable production to the Group producing 22,246 ounces of payable gold at a negative AISC of A$(447)/oz. Gold sales of Ernest Henry production commenced in the March 2017 quarter with 14,070oz sold, representing November and December 2016 production. March quarter production of 22,246oz will be delivered and sold during the June 2017 quarter which will be the first quarter in which Evolution receives a full three months of cash proceeds from Ernest Henry.
Mt Carlton delivered another exceptionally strong quarter despite a five day suspension at the end of March during Cyclone Debbie. 25,536 payable ounces of gold were produced at record low costs of C1 A$259/oz and an AISC of A$509/oz.
During the quarter the Board approved the Cowal E42 Stage H cutback and Dual Leach Project. This has secured a mine life for the operation of at least 15 years and creates further asset enhancement opportunities including:
-
Co-treatment of high-grade oxide stockpiles
-
Potential to increase throughput to 9.0 – 9.5 million tonnes per annum
-
Continued drilling to convert significant mineral endowment outside of existing Ore Reserves
Evolution today released its annual Mineral Resources and Ore Reserves[3] (MROR) estimates at 31 December 2016. A focus on extending the average mine life of its asset base has resulted in significant year-on-year improvements to mineral inventory with an average Group reserve life now more than eight years. Evolution is committed to building a sustainable business that prospers through the cycle and has therefore used an unchanged and conservative gold price assumption of A$1,350 per ounce (US$1,010/oz)[2] to estimate Reserves. Gold Ore Reserves increased by 1.14 million ounces (19%) year-on-year to 6.99 million ounces after accounting for mining depletion of 913,000 ounces.
Evolution expects gold production in the June 2017 quarter to be above 210,000 ounces and to comfortably deliver its FY17 guidance of 800 – 860koz. AISC are expected to be at the bottom end of the A$900 – A$960/oz guidance range while gated project capital approved by the Board in February for the Stage H cutback and Dual Leach Project at Cowal will add A$20 – A$25/oz to Group AISC in FY17.

Mining activities focussed on the E42 Stage G cutback to a current operating level of 903mRL.
Various activities were completed in preparation towards commencing trial mining of triple benches in the E42 Stage G pit. This design change is expected to improve berm retention, reduce rock fall incidents and improve inter-ramp slope angles. The project is in its initial stages and will continue throughout FY18.
During the quarter Board approval was received to proceed with the E42 Stage H cutback and construction of a Dual Leach circuit in the processing plant. Preparatory works are underway for the Stage H cutback with material movement planned to ramp up in the September 2017 quarter. Engineering design works are in progress for the Dual Leach Project with construction expected to commence in the December 2017 quarter. Expenditure of gated capital relating to these new projects at Cowal is expected to see AISC increase to around A$1,200 per ounce in the June 2017 quarter.
Subsequent to the end of the quarter, Cowal was awarded “NSW Mining Operation of the Year” at the NSW Mining Industry and Suppliers’ Awards.

Mungari, Western Australia (100%)
Mungari produced 33,915oz of gold at a C1 cash cost of A$1,046/oz and AISC of A$1,221/oz (Dec 2016 qtr: 41,645oz, C1 A$777/oz, AISC A$1,015/oz).
Mine operating cash flow for the quarter was A$21.0 million. Net mine cash flow of A$11.4 million was achieved (Dec 2016 qtr: A$21.7 million) post sustaining capital and major capital of A$9.6 million.
The Frog’s Leg underground mine produced 158kt ore tonnes at a grade of 4.5g/t. Total development increased by 15% compared to the December quarter. Ore production was focussed on the Mist diminishing pillar. Paste costs have been reduced by approximately 40% over the past 12 months.
Mining of the White Foil open pit continued to focus on Stage 2b. The Stage 3 cutback will be prioritised in the June quarter upon completion of Stage 2b. Unseasonably heavy rainfall throughout the quarter adversely impacted open pit activities. As a result, material movement was reduced to 2.4Mt. Drilling activities were increased as the pit transitioned to 100% drill and blast.
A full reline of the mill was successfully completed during the quarter. Recoveries improved to 93.8%. Work continued in preparation for a second Knelson concentrator and a particle size analyser to be installed in the June quarter.
As highlighted in the December 2016 Quarterly Report mined grades are expected to remain below reserve grade during the second half of FY17. Production in the June 2017 quarter is expected to be similar to the March 2017 quarter.

Edna May, Western Australia (100%)
Edna May produced 10,480oz at a C1 cash cost of A$1,772/oz and AISC of A$1,849/oz (Dec 2016 qtr: 18,588oz, C1 cash cost A$1,350/oz, AISC A$1,478/oz).
Unit costs increased due to lower gold production and significantly higher material movement.
Open pit mining was within the Stage 2 north cutback. Total material mined of 3,216kt was higher than the previous quarter (Dec 2016 qtr: 1,661kt) as impediments were removed and productivity improved.
The north cutback was in the pre-strip phase which allowed limited access to ore. A lack of available ore resulted in the processing plant incurring two shutdown periods totalling 17 days. Approximately 35% of ore processed during the quarter was sourced from low grade stockpiles.
Rehabilitation of the underground continued with an additional 508m of the decline completed plus 92m of level rehabilitation for infrastructure.
Although a lack of available ore translated to a poor March quarter, the turnaround is progressing at Edna May as a result of changes implemented under new management post the review of operations. Ore mined is expected to be substantially higher in the June 2017 quarter and throughout FY18 with increased availability of ore in the open pit. Edna May expects to produce between 20,000 – 25,000 ounces of gold at a significantly lower ASIC in the June 2017 quarter.

Ernest Henry, Queensland (Economic interest; 100% Gold and 30% Copper Production)[1]
The March 2017 quarter included the first full quarter of Evolution’s attributable production from the Ernest Henry operation. Evolution’s interest for the quarter delivered 22,246oz of payable gold and 4,997t of payable copper at an AISC of A$(447)/oz. The cost performance continues to be exceptional with a C1 cash cost of A$(645)/oz after accounting for copper and silver by-product credits (December qtr: 14,257oz payable gold and 3,125t of payable copper, C1 A$(481)/oz, AISC A$(114)/oz). Cash costs (C1) comprised of operating costs of A$1,110/oz and by-product credits of A$1,755/oz.
Ore mined was 1,640kt at an average grade of 0.56g/t gold and 1.12% copper. Underground development was 1,299m. Ore processed was 1,617kt at an average grade of 0.56g/t gold and 1.12% copper. Gold recovery of 79.2% and copper recovery of 95.4% was achieved with mill utilisation at 86.8%.
Copper sales in the quarter were 4,997t at an average copper price of A$7,726/t.
Gold sales of Ernest Henry production commenced in the March 2017 quarter with 14,070oz sold, representing November and December 2016 production. March quarter production of 22,246oz is not included in group gold sales or revenue for the March quarter, which is classified as inventory until sold, as per the Offtake Agreement. This gold will be delivered and sold during the June 2017 quarter which will be the first quarter in which Evolution receives a full three months of cash flow from Ernest Henry.
Operating mine cash flow for the quarter was A$33.9 million representing the gold (A$22.5 million) and by-product sales of copper (A$38.6 million) and silver (A$0.4 million) net of Evolution’s operating costs of A$27.7 million. Ernest Henry generated an impressive net mine cash flow for Evolution of A$32.4 million, post sustaining capital of A$1.4 million.

FINANCIALS
Evolution’s portfolio of assets has again delivered an exceptional financial result, with quarterly record lows achieved both for All-in Sustaining Cost and All-in Cost. Evolution’s strong operating result allowed for the debt repayments totalling A$40.0 million during the quarter as well as the payment of A$27.4 million in dividends net of the Dividend Reinvestment Program.
These payments were made possible as Evolution generated operating mine cash flow of A$166.5 million which was slightly lower than the December 2016 quarter of A$170.3 million due to a lower average gold price and lower gold ounces sold in the quarter. Importantly net mine cash flow of A$110.7 million achieved was higher than the December 2016 quarter of A$102.2 million due to lower capital investment. A total of A$55.7 million of capital was invested in the quarter with A$25.2 million in sustaining capital and $30.5 million in major project capital.
Evolution sold 193,431 oz of gold at an average gold price of A$1,600/oz (December 2016 qtr: 198,782 oz at A$1,603/oz). Deliveries into the hedge book totalled 60,495oz at an average price of A$1,580/oz with the remaining 132,936 oz of gold delivered on spot markets at an average price of A$1,611/oz.
All sites, with the exception of Edna May, were cash flow positive for the quarter after meeting all their operating and capital expenditure needs. Edna May continued to invest in the waste stripping in the open pit and development of the first stage of the underground mine. With higher production and lower capital investment planned at Edna May in the June 2017 quarter, an improved financial performance is expected.
In terms of net mine cash flow the standouts were Cowal (A$39.1 million), Ernest Henry (A$32.4 million) and Mt Carlton (A$22.2 million). Mungari’s net mine cash flow of A$11.4 million was down on last quarter due to lower production, whilst Cracow’s net mine cash flow of $11.6 million significantly improved on the previous quarter as a result of higher production and lower capital expenditure.

Capital investment for the quarter of A$55.7 million (December 2016 qtr: A$68.0 million) was in line with plan. During the quarter the main capital expenditure items included: Cowal resource definition drilling and Stage H related truck refurbishment costs (A$5.2 million); Edna May Southern and Northern cutbacks (A$10.4 million) and underground mine construction (A$2.7 million); Mt Rawdon capital waste stripping continued in the southern end of Stage 4 (A$4.5 million); Mungari capital waste stripping (A$3.1 million) and underground development (A$4.6 million); Cracow underground mine development (A$3.1 million); and Mt Carlton capital waste stripping in the northern section of Stage 3 (A$4.1 million).
FY17 Group capital expenditure is expected to be around the top end of the A$195.0 – A$250.0 million guidance range. This includes an additional A$20.0 million of gated capital approved by the Board in February associated with Cowal projects.
Discovery expenditure in the quarter totalled A$7.0 million (December 2016 qtr: A$9.0 million). The decreased expenditure reflects lower drilling activity of 32,264m (49,218m in December 2016 qtr). Corporate administration costs for the quarter were A$7.6 million (December 2016 qtr: A$6.7 million).

E42 step-out drilling and E42 exploration diamond drilling program
Activity comprised 10,987m of drilling with the completion of the Resource Definition program to the south west of the Stage H pit and commencement of exploration drilling between the E42 and E41 resources in a target zone named “Beagle”. Observations from drill core have identified the association of mineralisation to different phases of diorite within a composite intrusion. Two exploration holes (1,425m) were drilled this quarter.
Results from the step-out drilling confirmed the overall tenor of mineralisation is consistent with that delineated in the Stage H pit, however the zone is narrowing down-dip to the west. Significant intercepts included[1] :

EXPLORATION
Regional exploration
The transfer of the Marsden project[1] tenements (EL5524 & EL6593) was received this quarter. The East Girral tenement (EL8425) located 30km north north-west of the Cowal operation was also secured. An air core exploration drilling campaign will commence in the June 2017 quarter.
Mungari, Western Australia (100%)
Near mine exploration
Exploration drilling totalled 392 holes for 28,844m focusing at Ora Banda, Frog’s Leg East and in the Julius to Broads Dam areas.
At Ora Banda, framework RC and aircore drilling (18,041m) was completed on a number of tenements acquired as part of the Phoenix transaction. A number of new targets were identified analogous to existing mineralisation styles in the Ora Banda camp. Follow-up drilling is planned across the next two quarters.
A framework line of nine diamond holes (for 3,379m) was drilled east of the Frog’s Leg mine traversing 1.4km of stratigraphy with no previous bed rock drilling (>50m true depth). Drilling was undertaken to define the geology in a poorly understood area adjacent to the underground operations. Favourable stratigraphy and structures were identified reinforcing potential for parallel positions to the Frog’s Leg mine. Assay results are pending.
At Julius, six diamond holes (for 815m) were extended and seven additional RC holes (for 1,204m) were drilled to define the mineralisation to the south. All holes intersected the prospective structural-stratigraphic position without returning any significant intersections. Results will be incorporated in a regional geological model to further assist targeting of new positions along the structure which could host larger scale mineralisation.
Aircore drilling at the Blue Funnel South targeted a 7km section of the Zuleika Shear Zone in a location where interpretations of seismic data have identified architecture favourable for hosting gold mineralisation. A total of 24 holes for 1,629m were drilled completing 3 sections of the 19 line program. Results from the first two of the 350m spaced lines are encouraging with anomalous gold encountered along all three fences. The remainder of the program will be completed in the September 2017 quarter.
Resource definition drilling
Drilling of the Burgundy, Backflip, Carbine North, Kintore, Red Dam resources within the Mungari Regional projects totalled 10,177.4m. In addition, a drill program to sterilise a site for a third Tailings Storage Facility near the Mungari plant was completed.
The intent of the regional resource definition programs is to evaluate and prioritise the remaining resources and to advance them through the project pipeline to Ore Reserves.

Regional exploration
Exploration focussed on the Walhalla and Valkyrie Prospects located 2.5km north-east and 1.5km north-west from the Cracow Gold Field respectively. Work completed at these two locations included geological mapping, spectral analysis and interpretation of alteration zones, and rock-chip sampling which returned highly anomalous results. Interpretation of this data concluded that both prospects are preserved in the upper levels of a potentially mineralised epithermal system. Both targets will be drilled in the June 2017 quarter.
Tennant Creek, Northern Territory (earning 65% in Stage 1)
An ultra-detailed gravity survey was completed at Edna Beryl in March 2017. The survey delineated the small ironstone occurrences which host high grade gold mineralisation in the shallow underground workings. The survey will be extended further along strike to the east and west to screen for blind ironstone bodies capable of hosting additional mineralisation. Field work is expected to recommence in earnest during Q4 FY17.
Evolution and Emmerson Resources agreed to extend the Stage 1 earn-in period until 31 December 2017.

EXPLORATION
Puhipuhi, New Zealand (100%)
Compilation and integration of recently received assay and multi-element geochemical data was completed during the quarter. No new fieldwork was undertaken. The Discovery Group is presently reviewing exploration opportunities to be prioritised in FY18. A decision on future commitments at Puhipuhi will be made upon completion of this review process.
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 3 of this report.
Mineral Resources and Ore Reserves
Evolution today announced the outcome of its annual Mineral Resource and Ore Reserve estimates (refer to ASX release “Annual Mineral Resources and Ore Reserves Statement” dated 20 April 2017).
Evolution is committed to building a sustainable business that prospers through the cycle and therefore an unchanged and conservative gold price assumption of A$1,350 per ounce (US$1,010/oz) was used for the Ore Reserves estimates.
Group Ore Reserves at 31 December 2016 are estimated at 6.99 million ounces of gold and 212,000 tonnes of copper compared with the 31 December 2015 estimate of 5.85 million ounces of gold and 16,000 tonnes of copper. The net increase of 1.14 million ounces of gold is after accounting for mining depletion of 913,000 ounces of gold.
Highly successful resource definition drilling programs totalling 178,380 drilled metres in 2016 resulted in all six owned operations reporting an increase in Ore Reserves prior to mining depletion.
Group Mineral Resources at 31 December 2016 are estimated at 14.18 million ounces of gold and 1.03 million tonnes of copper compared with the estimate at 31 December 2015 of 14.01 million ounces of gold and 28,000 tonnes of copper. This represents a net increase of 0.16 million ounces after accounting for mining depletion of 0.91 million ounces of gold.
Further details are provided in Appendix 2 of this release.

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.

APPENDIX 1 – ERNEST HENRY REPORTING
This Appendix outlines the reporting of Evolution’s share of its economic interest in the Ernest Henry operation.
Production
Gold and copper concentrate production is reported in the same month as it is produced at Ernest Henry.
Sales
Copper and silver sales revenue are recognised in the same month as their production is reported. Copper and silver is sold in accordance with the Offtake Agreement with Glencore where the metal is received and sold immediately. Settlement is in the form of cash in the third month after the month of production. The price of the copper and silver will be determined by reference to the average monthly price for the second month after the month of production.
Gold sales and gold revenues are recognised when the metal is received and sold by Evolution. In accordance with the Offtake Agreement with Glencore, bullion is delivered to Evolution’s metal account in the third month after the month of production.
AISC and AIC metrics for the 2017 financial year will be reported from the month of November 2016. Gold produced will be assumed to equal gold sold when calculating AISC and AIC until the fourth quarter of the 2017 financial year (the first full quarter of gold sales). Thereafter, the actual volume of gold sold in the respective quarters will be used to calculate AISC and AIC.
Production and development costs
For financial reporting (statutory) purposes, monthly production costs are allocated between copper concentrate and gold based on their relative market value. Production costs are expensed when the product is received and sold by Evolution.
For quarterly reporting purposes in the 2017 financial year, Evolution’s share of all cash production costs for Ernest Henry will be reported in the same quarter as the costs are incurred. In subsequent periods, amounts reported quarterly will be in line with the amount reported for statutory purposes.
Amortisation of prepayment
For accounting purposes, the A$880.0 million upfront payment for the Ernest Henry economic interest has been allocated to gold (A$384.0 million) and copper (A$496.0 million) concentrate and will be amortised in line with the sales profile of the gold and copper concentrate. Consistent with cash production costs, amortisation is expensed when the product is sold.
For the 2017 financial year, amortisation expense is expected to be 6.6% of the A$880.0 million (5.1% of gold and 7.8% of copper). In subsequent years it is expected that between 10.0 to 12.0% of the A$880.0 million will be amortised. The expected annual amortisation rate will be provided each year as a part of annual guidance.
For income tax purposes, Evolution has obtained an Australian Taxation Office (ATO) ruling to adopt a similar methodology as accounting for allocating and depleting the A$880.0 million upfront payment across the sales profile of the gold and copper concentrate.

APPENDIX 1 – ERNEST HENRY REPORTING
Cash Flow
Proceeds from sales are received in the third month after the month that production is reported.
In accordance with the Offtake Agreement with Glencore, Evolution pays its share of operating and development expenditures in the third month after the month of production.
The table below outlines the timing and recognition of Evolution’s share of its interest in Ernest Henry for the 2017 Financial Year.

Cowal
Cowal Section 1 Sampling Techniques and Data
| 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). |
Holes in this report consist of both navigational and conventional diamond core drilling. Drill holes were positioned strategically to infill gaps in the existing drill data set and test continuity of known lodes/mineralised structures. Collar and down hole surveys were utilised to accurately record final locations. Industry standard sampling, assaying and QA/QC practices were applied to all holes. Drill core was halved with a diamond saw in 1 m intervals, irrespective of geological contacts. 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 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. The detection limit was 0.01 g/t Au. |
| Drilling techniques | Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face- sampling bit or other type, whether core is oriented and if so, by what method, etc.). |
Diamond drill holes were drilled HQ diameter through the clay/oxide and NQ diameter through the primary rock to end of hole. All core has been oriented using accepted industry techniques. |
| 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. |
Provisions are made in the drilling contract to ensure that hole deviation is minimised and core sample recovery is maximised. This is monitored by a geologist on a hole by hole basis. Core recovery is recorded in the database. There are no significant core loss or sample recovery issues. Core is reoriented and marked up at 1 m intervals. Measurements of recovered core are made and reconciled to the driller’s depth blocks, and if necessary, to the driller’s rod counts. There is no apparent relationship between core-loss and grade. |

APPENDIX 3 – JORC CODE 2012 ASSESSMENT AND REPORTING CRITERIA
| Criteria | Explanation | Commentary |
|---|---|---|
| Logging | Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. Whether logging is qualitative or quantitative in nature. Core (or costean, channel etc.) photography. The total length and percentage of the relevant intersections logged. |
Geologists log core for lithology, alteration, structure, and veining. Logging was done directly onto laptop computers via LogChief software which is validated and uploaded directly into the Datashed database. The Cowal logging system allows recording of both a primary and a secondary lithology and alteration. Geologists also record the colour, texture, grain size, sorting, rounding, fabric, and fabric intensity characterising each lithological interval. The logged structures include faults, shears, breccias, major veins, lithological contacts, and intrusive contacts. Structures are also recorded as point data to accommodate orientation measurements. Structural measurements are obtained using a core orientation device. Core is rotated into its original orientation, using the Gyro survey data as a guide. Freiberg compasses are used for structural measurements. Geologists log vein data including vein frequency, vein percentage of interval, vein type, composition, sulphide percentage per metre, visible gold, sulphide type, and comments relative to each metre logged. Geotechnical logging is done by field technicians and geologists. Logging is on a per metre basis and includes percentage core recovery, percentage RQD, fracture count, and an estimate of hardness. The geotechnical data is entered into the database. All drill core, once logged, is digitally photographed on a core tray- by-tray basis. The digital image captures all metre marks, the orientation line (BOH) and geologist’s lithology, alteration, mineralogy, and other pertinent demarcations. The geologists highlight geologically significant features such that they can be clearlyreferencedinthe digital images. |
| Sub-sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. For all sample types, the nature, quality and appropriateness of the sample preparation technique. Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. Whether sample sizes are appropriate to the grain size of the material being sampled. |
Diamond Core is cut with a diamond saw or chisel. Core is cut to preserve the bottom of hole orientation mark and the top half of core is always sent for analysis to ensure no bias is introduced. In 2003 Analytical Solutions Ltd conducted a Review of Sample Preparation, Assay and Quality Control Procedures for Cowal Gold Project. This study, combined with respective operating company policy and standards (North Ltd, Homestake, Barrick and Evolution) formed the framework for the sampling, assaying and QAQC protocols used at Cowal to ensure appropriate and representative sampling. Results per interval are reviewed for half core samples and if unexpected or anomalous assays are returned an additional quarter core may be submitted for assay. |
| Quality of assay data and laboratory tests |
The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. For geophysical tools, spectrometers, handheld XRF instruments etc. the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. |
SGS West Wyalong acts as the Primary Laboratory and ALS Orange conducts independent Umpire checks. Both labs operate to international standards and procedures and take part in the Geostatistical Round Robin inter-laboratory test survey. The Cowal QA/QC program comprises blanks, Certified Reference Material (CRM), inter-laboratory duplicate checks, and grind checks. 1 in 30 fine crush residue samples has an assay duplicate. 1 in 20 pulp residue samples has an assay duplicate. Wet screen grind checks are performed on 1 in 20 pulp residue samples. A blank is submitted 1 in every 38 samples, CRM’s are submitted 1 in every20 samples. The frequencyof repeat assays |

is set at 1 in 30 samples. All sample numbers, including standards and duplicates, are pre- assigned by a QA/QC Administrator and given to the sampler on a sample sheet. The QA/QC Administrator monitors the assay results for non-compliance and requests action when necessary. Batches with CRM’s that are outside the ±2SD acceptance criteria are re-assayed until acceptable results are returned. Material used for blanks is uncertified, sourced locally, comprising fine river gravel which has been determined to be below detection limit. A single blank is submitted every 38 samples. Results are reviewed by the QA/QC Administrator upon receipt for non- compliances. Any assay value greater than 0.1 g/t Au will result in a notice to the laboratory. Blank assays above 0.20 g/t Au result in re-assay of the entire batch. The duplicate assays (Au2) are taken by the laboratory during the subsampling at the crushing and pulverisation stages. The results were analysed using scatter plots and relative percentage difference (RPD) plots. Repeat assays represent approx. 10% of total samples assayed. Typically there is a large variance at the lower grades which is common for low grade gold deposits, however, the variance decreases to less than 10% for grades above 0.40 g/t Au, which is the cut-off grade used at Cowal. Approximately 5% of the pulps, representing a range of expected grades, are submitted to an umpire assay laboratory (ALS Orange) to check for repeatability and precision. Analysis of the data shows that the Principal Laboratory is performing to an acceptablelevel. |
|
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. The use of twinned holes. Documentation of primary data, data entry procedures, data verification and data storage (physical and electronic) protocols. Discuss any adjustment to assay data |
No dedicated twinning drilling has been conducted for this drill program however some holes pass through areas of higher confidence material in order to reach target zones. These areas may be used to validate exiting drill information. 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 canuse and sort the database butnot save ordelete data. |
| Location of data points |
Accuracy and quality of surveys used to locate drillholes (collar and downhole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Specification of the grid system used. Quality and adequacy of topographic control. |
All 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 areaswithintheMLandELs at Cowal withsixdigits. |
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral _Resource and Ore Reserve estimation _ |
Drill holes were strategically positioned to infill gaps in the existing data set. All drilling is sampled at 1 m intervals down hole. |

| procedure(s) and classifications applied. Whether sample compositing has been applied. |
||
| Orientation of data in relation to geological structure |
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
Diamond holes were positioned to optimise intersection angles of the target area. There is no apparent bias in terms of the drill orientation that has been noted to date. |
| 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 andresolvedwiththelaboratory. |
| 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 ordata quality. |

The Cowal region has been subject to various exploration and drilling programs by GeoPeko, North Ltd., Rio Tinto Ltd., Homestake and Barrick. |
||
| Geology | Deposit type, geological setting and style of mineralisation. |
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 230 m 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). |

Mungari
Mungari Section 1 Sampling Techniques and Data
| 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 gold mineralisation at Mungari was undertaken using diamond core (surface and underground) 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 or 4m downhole intervals. Sampling was carried out according to Evolution protocols and QAQC procedures which comply with industry best practice. Most drill-hole collars were surveyed using a total station theodolite or total GPS with a small proportion utilising hand held 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 or 4m samples 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 1.3m. 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. |
| 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.). |
RC sampling was completed using a 4.5” to 5.5” diameter face sampling hammer. Diamond holes are predominantly wireline NQ2 (50.5mm) or HQ (63.5mm) holes. All diamond core was orientated using the reflex (act II or ezi- ori) 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 |
RC drilling sample weights were recorded for selected sample intervals and monitored for fluctuations against the expected sample weight. If samples were below the expected weight, feedback was given promptly to the RC driller to modify drilling practices to achieve the expected weights.

core was orientated and measured during processing and the recovery recorded into the drill-hole database. The core was reconstructed into continuous runs on a cradle for orientation marking. Holes depths were checked against the driller’s core blocks. Inconsistencies between the logging and the driller’s core depth measurement blocks were investigated. Core recovery has been excellent as all holes are drilled into fresh competent rock. Surface drilling recoveries were generally excellent with the exception of oxide zones however these rarely fell below 90%. Measures taken to maximise sample recovery include instructions to drillers to slow down drilling rates or reduce the coring run length in less competent ground. Analysis of drill sample bias and loss/gain was undertaken with the Overall Mine Reconciliation performance where available. |
|
| Logging | Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. Whether logging is qualitative or quantitative in nature. Core (or costean, channel etc.) photography. The total length and percentage of the relevant intersections logged. |
RC drill chips and diamond core has been geologically logged to the high level of detail required for the Mineral Resource estimation, mining studies and metallurgical studies. All logging is both qualitative and quantitative in nature recording features such as structural data, RQD, sample recovery, lithology, mineralogy, alteration, mineralisation types, vein density, oxidation state, weathering, colour etc. All holes are photographed wet. All RC and diamond holes were logged in entirety from collar to end of hole. |

If core, whether cut or sawn and whether quarter, half or all core taken. If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. For all sample types, the nature, quality and appropriateness of the sample preparation technique. Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. Whether sample sizes are appropriate to the grain size of the material being sampled. |
Most diamond core drilled from surface was half cored 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. Regular 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 75) 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 50g fire assay charge. The pulp is retained and the bulk residue is disposed of after two months. |

|---|---|---|
| Measures taken to ensure sample representation include the collection of field duplicates during RC drilling at a frequency rate of 5%, and quarter core sampling of surface diamond drill holes. 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. |

| Quality of assay data and laboratory tests |
The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. For geophysical tools, spectrometers, handheld XRF instruments etc. the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. |
The sampling preparation and assaying protocol used at 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. |
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. The use of twinned holes. Documentation of primary data, data entry procedures, data verification and data storage (physical and electronic) protocols. Discuss any adjustment to assay data |
Independent internal or external verification of significant intercepts is not routinely completed. The quality control / quality assurance (QAQC) process ensures the intercepts are representative for the orogenic gold systems. Half core and sample pulps are retained at Mungari if further verification is required. The twinning of holes is done as necessary for validation purposes. 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 assaydata reported bythe laboratory. |
| Location of data points |
Accuracy and quality of surveys used to locate drillholes (collar and downhole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Specification of the grid system |
All surface drill holes at Mungari have been surveyed for easting, northing and reduced level. Recent data is collected and stored in MGA 94 Zone 51 and AHD. Resource drill hole collar positions are surveyed by the site- based survey department or contract surveyors (utilising a differential GPS or conventional surveying techniques, with reference to a known base station) with a precision of less than 0.2m variability. |

| used. Quality and adequacy of topographic control. |
The RC and surface drill hole survey data consists of surveys taken utilising north seeking gyro instruments. Gyro survey measurements are obtained every 5 to 10m down hole. A proportion of these holes are downhole surveyed using a digital single shot survey technique similar to that of the underground holes, except the down-hole survey measurement is at a spacing typically 25-50m apart. Topographic control was generated from aerial surveys and detailed Lidar surveys to 0.2m accuracy. Underground void measurements are computed using Cavity Monitoring System (CMS) of the stopes and detailed survey pickup of the development. |
|
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. Whether sample compositing has been applied. |
The nominal drill spacing for Exploration drilling is 80m x 80m or wider and for Resource Definition is 40m x 40m or in some areas 20m x 20m. Drill spacing is reviewed for each project an does vary. This spacing includes data that has been verified from previous exploration activities on the project. Data spacing and distribution is considered sufficient for establishing geological continuity and grade variability appropriate for classifying a Mineral Resource. Sample compositing was not applied due to the often narrow mineralised zones. |
| Orientation of data in relation to geological structure |
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
Resource Definition drilling is 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 test for alternate geological interpretations. |
| Sample security | The measures taken to ensure sample security. |
Chain of custody protocols to ensure the security of samples were followed. Prior to submission samples were retained on site and access to the samples were 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 have remained 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. |

Geology Deposit type, geological setting and style of mineralisation. The Burgundy prospect is located in the central portion of the Mungari tenements and is structurally related to the Kunanulling Shear Zone and Telegraph Syncline. Mineralisation occurs as a stockwork vein array within a sheared dolerite/microdolerite on the western limb of the Telegraph syncline. A narrow and more diffuse zone of mineralisation occurs within volcaniclastic sediments approximately 50m into the hangingwall from the main zone. Mineralisation is truncated by at least 2 late D4 faults in the order of 10’s m. |

| 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. Intercept length weighted average techniques, minimum grade truncations and cut-off grades have been used in this report. 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. If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. There is a direct relationship between the mineralisation widths and intercept widths at Mungari. The assay results are reported as down hole intervals however an estimate of true width is provided in Appendix. |

Sample types collected at Cracow and used in the reporting of assays were all diamond drill core Sample intervals for drill core were determined by visual logging of lithology type, veining style/intensity and alteration style/intensity to ensure a representative sample was taken. In addition, sampling is completed across the full width of mineralisation. Minimum and maximum sample intervals were applied using this framework. No instruments or tools requiring calibration were used as part of the sampling process. Industry standard procedures were followed with no significant coarse gold issues that affected sampling protocols. Nominal 3 kg samples from drill core are subsampled to produce a 50g sample submitted for fire assay. |

|
| 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. |
Drill core – the measurement of length drilled Vs. length of core recovered was completed for each drilled run by the drill crew. This was recorded on a core loss block placed in the core tray for any loss identified. Marking up of the core by the geological team then checked and confirmed these core blocks, and any additional core loss was recorded and blocks inserted to ensure this data was captured. Any areas containing core loss were logged using the lithology code “Core Loss” in the lithology field of the database. Sample loss at Cracow was calculated at less than 1% and wasn’t considered an issue. Washing away of sample by the drilling fluid in clay or fault gouge material is the main cause of sample loss. In areas identified as having lithologies susceptible to sample loss, drilling practices and down-hole fluids were modified to reduce or eliminate sample loss. The drilling contract used at Cracow states for any given run, a level of recovery is required otherwise financial penalties are applied to the drill contractor. This ensures sample recovery is prioritised along with production performance. Mineralisation at Cracow was within Quartz-Carbonate fissure veins, and therefore sample loss rarely occurs in lode material. No relationship between sample recovery and grade was observed. |
| Logging | Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. Whether logging is qualitative or quantitative in nature. Core (or costean, channel etc) photography. The total length and percentage of the relevant intersections logged. |
Geological logging was undertaken onsite by Evolution employees and less frequently by external contractors. Logging was completed using_LogChief_Software and uploaded directly to the database. A standard for logging at Cracow was set by the Core Logging Procedure_Cracow Procedures Manual 3rd_ Edition. Drill Core is logged recording lithology, alteration, veining, mineral sulphides and geotechnical data. RC chip logging captured the same data with the exclusion of geotechnical information. Logging was qualitative. All drill core was photographed wet using a camera stand and an information board to ensure a consistent standard of photography and relevant information was captured. All core samples collected were fully logged. |

All drill holes reported were whole core sampled. Whole core samples were crushed in a jaw crusher to > 70% passing 2mm; half of this material was split with a riffle splitter for pulverising. No RC samples required crushing in the jaw crusher. Core and RC samples were pulverised for 10-14 minutes in a LM5 bowl with a target of 85% passing 75µm. Grind checks were undertaken nominally every 20 samples. From this material approximately 120g was scooped for further analysis and the remaining material re-bagged. Duplicates were performed on batches processed by ALS every 20 samples at both the crushing and pulverising stages. This sample preparation for drill samples is considered appropriate for the style of mineralisation at Cracow. Duplicates were performed on batches processed by ALS Brisbane every 20 samples at both the crushing and pulverising stages. Grind checks were undertaken nominally every 20 samples, to ensure sample grind target of 85% passing 75µm was met. Duplicates were completed every 20 samples at both the |

Sample Analyses – The samples were analysed by 50g Fire Assay for Au with Atomic Absorption (AAS) finish and was performed at ALS Townsville. For Ag an Aqua Regia digest with AAS finish was completed, also at ALS Townsville. An analytical duplicate was performed every 20 samples, aligned in sequence with the crushing and pulverising duplicates. The Fire Assay Method is a total technique. No other instruments that required calibration were used for analysis to compliment the assaying at Cracow. Thirteen externally certified standards at a suitable range of gold grades (including blanks) were inserted at a minimum rate of 1:20 with each sample submission. All non-conforming results were investigated and verified prior to acceptance of the assay data. Results that did not conform to the QAQC protocols were not used in resource estimations. Monthly QAQC reports were produced to watch for any trends or issues with bias, precision and accuracy. An inspection of both the prep lab in Brisbane and the assay lab in Townsville was conducted in December 2016 by Cracow personnel. |
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. The use of twinned holes. Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. Discuss any adjustment to assay data |
Verification of assay results was standard practice, undertaken at a minimum once per year. In 2015, 547 pulp samples from Cracow drillcore were retested at SGS Townsville to compare to the results produced by ALS Townsville. The umpire sampling confirmed the accuracy of the ALS Townsville assaying was within acceptable error limits. The drilling of twin holes wasn’t common practice at Cracow. Twin holes that have been drilled show the tenor of mineralisation within the reportable domains were consistent between twin holes. All sample information was stored using_Datashed_, an SQL database. The software contains a number of features to ensure data integrity. These include (but not limited to) not allowing overlapping sample intervals, restrictions on entered into certain fields and restrictions on what actions can be performed in the database based on the individual user. Data entry to_Datashed_ was undertaken through a combination of site specific electronic data-entry sheets, synchronisation from_Logchief_and upload of .csv files. No adjustments are made to the finalised assay data received from the laboratory. |

Sample intervals for most domains were composited to 1m, with a maximum sample length of no greater than 1.5m and a minimum sample interval of 0.2m. A small number of lodes utilised a 1.5m composite as was appropriate for the sample set for those deposits. |

| Orientation of data in relation to geological structure |
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
Sample bias from non-orientation of core is considered minimal in respect to mineralisation at Cracow. All drill holes reported were whole core sampled Drill holes were designed to ensure angles of sample intersection with the mineralisation was as perpendicular as possible. Where a poor intersection angle of individual holes locally distorted the interpreted mineralisation, these holes may not have been used to generate the wireframe. |
| Sample security | The measures taken to ensure sample security. |
All staff undergo Police Clearances, are instructed on relevant JORC 2012 requirements and assaying is completed by registered laboratories. The core was transported by a private contractor by truck to the assay laboratories. |
| Audits or reviews | The results of any audits or reviews of sampling techniques and data. |
An inspection of sample preparation facility in Brisbane and the Fire Assay laboratory in Townsville was conducted in by Cracow personnel in December 2015. No major issues were found. |

The Cracow Goldfields were discovered in 1932, with the identification of mineralisation at Dawn then Golden Plateau in the eastern portion of the field. From 1932 to 1992, mining of Golden Plateau and associated trends produced 850Koz. Exploration across the fields and nearby regions was completed by several identities including BP Minerals Australia, Australian Gold Resources Ltd, ACM Operations Pty Ltd, Sedimentary Holdings NL and Zapopan NL. In 1995, Newcrest Mining Ltd (NML) entered into a 70 % share ofthe CracowJointVenture. Initially exploration was targeting |

| porphyry type mineralisation, focusing on the large areas of alteration at Fernyside and Myles Corridor. This focus shifted to epithermal exploration of the western portion of the field, after the discovery of the Vera Mineralisation at Pajingo, which shared similarities with Cracow. The Royal epithermal mineralisation was discovered in 1998, with further discoveries of Crown, Sovereign, Empire, Phoenix, Kilkenny and Tipperary made from 1998 up to 2008 Evolution was formed from the divestment of Newcrest assets (including Cracow) and the merging of Conquest and Catalpa in 2012. Evolution continued exploration at Cracow from 2012. |

| Geology | Deposit type, geological setting and style of mineralisation. |
The Cracow project area gold deposits are in the Lower Permian Camboon Andesite on the south-eastern flank of the Bowen Basin. The regional strike is north-northwest and the dip 20° west-southwest. The Camboon Andesite consists of andesitic and basaltic lava, with agglomerate, tuff and some inter-bedded trachytic volcanics. The andesitic lavas are typically porphyritic, with phenocrysts of plagioclase feldspar (oligocalse or andesine) and less commonly augite. To the west, the Camboon Andesite is overlain with an interpreted disconformity by fossiliferous limestone of the Buffel Formation. It is unconformably underlain to the east by the Torsdale Beds, which consist of rhyolitic and dacitic lavas and pyroclastics with inter-bedded trachytic and andesitic volcanics, sandstone, siltstone, and conglomerate. Mineralisation is hosted in steeply dipping low sulphidation epithermal veins. These veins found as discrete and as stockwork and are composed of quartz, carbonate and adularia, with varying percentages of each mineral. Vein textures include banding (colloform, crustiform, cockade, moss), breccia channels and massive quartz, and indicate depth within the epithermal system. Sulphide percentage in the veins are generally low (<3%) primarily composed of pyrite, with minor occurrences of hessite, sphalerite and galena. Rare chalcopyrite, arsenopyrite and bornite can also be found. Alteration of the country rock can be extensive and zone from the central veined structure. This alteration consists of silicification, phyllic alteration (silica, sericite and other clay minerals) and argillic alteration in the inner zone, grading outwards to potassic (adularia) then an outer propylitic zone. Gold is very fined grained and found predominantly as electrum but less common within clots of pyrite. |

| Competent Person should clearly explain why this is the case. |
||
| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg 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. |
Intercept length weighted average techniques, and minimum grade truncations and cut-off grades have been used in this report. Due to the nature of the drilling, some composite grades are less than the current resource cut off of 2.8g/t, but remain significant as they demonstrate mineralisation in veins not previously modelled. Composite, as well as internal significant values are stated for clarity. No metal equivalent values are used. |
| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. If it is not known and only the downhole lengths are reported, there should be a clear statement to this effect (eg ‘downhole length, true width not known’) |
The sampling technique confirms the presence of epithermal quartz veining. There is a direct relationship between the mineralisation widths and intercept widths at Cracow. The assays are reported as down hole intervals and an estimated true width is provided. |
| Diagrams | Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported. These should include, but not be limited to a plan view of drill hole |
