OPERATIONS
Group gold production for the December 2016 quarter was a record 217,812 ounces (Sep qtr: 205,307oz). Average C1 cash cost declined 22% compared to the prior quarter to a record low A$585/oz (Sep qtr: A$753/oz). AISC[1] declined 15% to A$900/oz (Sep qtr: A$1,060/oz). Using the average AUD:USD exchange rate for the quarter of 0.7505, Evolution’s Group C1 cash cost equated to US$439/oz and Group AISC to US$675/oz.
In the December 2016 quarter Evolution delivered operating mine cash flow of A$170.3 million and net mine cash flow, post all sustaining and major capital, of A$102.1 million (Sep qtr: operating cash flow A$169.3 million; net mine cash flow A$111.4 million). This was another strong quarter of cash generation despite the average achieved gold price being A$105/oz lower than the prior quarter. It allowed Evolution to make debt repayments totalling A$70.0 million during the quarter. The cash flow for the quarter does not include any revenue from Ernest Henry gold sales which will commence from the March 2017 quarter (refer Appendix 1 for details on Ernest Henry reporting).
As at 31 December 2016, gross debt outstanding under the Senior Secured Syndicated Revolving and Term Facility was A$600.0 million. Net debt was reduced to A$588.5 million after peaking at $647.3 million during the quarter. The strong cash flow enabled the Company to meet all of its mandatory debt repayments through to October 2017.
Cowal had another standout quarter producing 71,903 ounces at an AISC of A$815/oz – achieving record quarterly production under Evolution’s 17 months of ownership. Mt Carlton delivered exceptionally low costs with 25,674 payable ounces produced at C1 costs of A$277/oz and an AISC of A$604/oz.
Ernest Henry made a strong initial contribution to the portfolio during the quarter with 14,257 ounces of gold produced at an AISC of A$(114)/oz. This represented two months of production with reporting commencing 1 November 2016. The cash proceeds from Ernest Henry’s gold production of approximately $23.0 million[2] will be received in the March quarter. Formal confirmation has been received from the Australian Tax Office for the amortisation of the A$880.0 million pre-payment as metal is received and sold by Evolution.
Stage H definition drilling was completed at Cowal with results successfully confirming the presence of a large, richly mineralised zone. A program of step-out exploration drilling was initiated to delineate the full extent of mineralisation beyond the limits of the Stage H pit design and a number of significant results have been returned.
At Mungari, follow-up drilling at Frog’s Leg East encountered narrow laminated vein intercepts along a mineralised structure 1km east of the main Frog’s Leg underground operation. Further drilling is underway to assess the potential for economically significant mineralisation to be hosted in adjacent structural positions.
Following a record quarter Evolution expects to comfortably deliver into its FY17 production and cost guidance of 800 – 860koz at an AISC of A$900 – A$960/oz.

OPERATIONS
Cowal, New South Wales (100%)
Cowal achieved record gold production under Evolution ownership in the December quarter with 71,903oz of gold produced at a C1 cash cost of A$518/oz and AISC of A$815/oz (Sep 2016 qtr: 64,032oz, C1 A$687/oz and AISC A$907/oz).
Mine operating cash flow for the quarter was A$60.4 million. Cowal delivered net mine cash flow of A$45.7 million (Sep 2016 qtr: A$51.5 million), post capital of A$14.7 million.
Mining activities focussed on the Stage G cutback to a current operating level of 912mRL.
As per the mine plan, grades in the second half of the year are expected to be lower than the first half.
During the December quarter, three second-hand 785C trucks were purchased and commissioned as replacements for older trucks. Improved productivities and utilisation rates are anticipated in the March 2017 quarter.
E42 resource definition drilling as part of the Stage H cutback feasibility study was completed ahead of time, under budget and delivered strong results. A Board decision on whether to proceed with the Stage H cutback is expected in the March 2017 quarter following completion of the feasibility study. Gated capital for an incremental phase of E42 resource definition drilling was approved during the December quarter and commenced immediately after the completion of Stage H drilling.
Mungari, Western Australia (100%)
Mungari produced 41,645oz of gold at a C1 cash cost of A$777/oz and AISC of A$1,015/oz (Sep 2016 qtr: 38,295oz, C1 A$897/oz, AISC A$1,081/oz).
Mine operating cash flow for the quarter was A$35.1 million. Mungari delivered net mine cash flow of A$21.7 million, post sustaining capital and major capital of A$13.3 million.
The Frog’s Leg underground mine produced 6% more ore tonnes at a 40% higher grade than the September quarter due to access to higher grade stopes in the Mist orebody. Less rehabilitation work was required compared to previous quarters as a result of significant ground support upgrades completed earlier in 2016. A drill platform for the Mist orebody will be developed in the June 2017 half to test the resource further at depth.
Mining of the White Foil open pit continued to focus on Stage 2b and Stage 3. Rain water in Stage 2b significantly reduced the productivity of drill and blast activities. More drilling capacity is being sourced to address the ground and water conditions. Despite the issues in Stage 2b, total open pit material movement increased by 13% to 2.9Mt. Waste movement accounted for 92% of White Foil’s total material movement in the quarter.
As per the mine plan, grades in the second half of the year are expected to be lower than the first half.
Processing recoveries improved to 93.6% in the quarter (Sep 2016 qtr: 91.7%). The processing issues from the previous quarter were rectified with particular focus on the milling and leaching parameters of the circuit. Paste dilution was also reduced at Frog’s Leg along with an overall improved head grade.

Edna May, Western Australia (100%)
Gold production of 18,588oz was achieved in the December quarter at a C1 cash cost of A$1,350/oz and AISC of A$1,478/oz (Sep 2016 qtr: 20,012oz, C1 cash cost A$1,327/oz, AISC A$1,472/oz).
Mine operating cash flow for the quarter was A$7.6 million. Edna May reported negative net mine cash flow of A$(0.9) million, post sustaining capital and major capital of A$8.5 million. Excluding the A$3.9 million expended on the underground mine development, Edna May would have been cash positive for the quarter.
A full review of the operation was undertaken during the quarter with a number of management changes made. As a result of this review a plan is being implemented to materially improve mobile fleet productivities. Steps have been put in place to target higher volume open pit mining by removing Bore 6 in the North Cutback and completing mining at the base of the pit. Material movement from the open pit is expected to increase to 1Mt per month in the June 2017 half year. The impact of these changes should reduce the AISC materially in the second half of the year.
Cracow, Queensland (100%)
Cracow produced 19,763oz of gold in the December quarter at a C1 cash cost of A$782/oz, and AISC of A$1,283/oz (Sep 2016 qtr: 21,554oz, C1 A$856/oz, AISC A$1,253/oz).
Mine operating cash flow for the quarter was A$13.6 million. Cracow delivered a net mine cash flow of A$3.6 million, post sustaining capital and major capital of A$10.0 million.
Cracow continues to operate without a lost time injury and reduced the TRIFR from 18.8 at the end of June 2016 to 10.7 at the end of December 2016.
A total of 136kt of ore was mined at an average grade of 4.77g/t gold. Primary ore sources were the Kilkenny and Empire ore bodies. Grades are expected to improve in the June 2017 half with the increased production from Kilkenny transverse stopes and Empire 1854 level.
Ore processed was 139kt at an average grade of 4.72g/t gold. Gold recovery was 93.8%. Plant utilisation fell to 95.6% due to a planned extended shutdown enabling the installation of tie-in facilitation of the fine grind mill.
The rehabilitation of underground infrastructure continued with an additional 918m of decline completed. Development of the underground mine remains on track with first production expected in early FY18.

Ernest Henry, Queensland (Eonomic interest; 100% Gold and 30% Copper Production)[1]
Following the completion of the Ernest Henry transaction, attributable production commenced on 1 November 2016. Production for the 61 days of Evolution’s interest during the quarter delivered 14,257oz of gold and 3,125t of copper. The cost performance was exceptional at a C1 cash cost of A$(481)/oz, and AISC of A$(114)/oz, after accounting for copper and silver by-product credits. Cash costs (C1) comprised operating costs of A$1,208/oz and by-product credits of A$(1,689)/oz.
Copper sales in the quarter were 3,125t at an average copper price of A$7,619/t.
Ernest Henry’s gold production of 14,257oz is not included in group gold sales or revenue for the December quarter, which is classified as inventory until sold, as per the Offtake Agreement (refer Appendix 1 for details on Ernest Henry reporting). This gold will be delivered and sold during the March 2017 quarter.
Mine operating cash flow for the quarter was A$4.8 million representing the by-product sales of copper (A$23.8 million) and silver (A$0.3 million) that were produced during the quarter net Evolution’s operating costs of A$19.3 million. Ernest Henry generated net mine cash flow for Evolution of A$1.6 million, post sustaining capital of A$3.2 million.
Ore mined was 1,013kt at an average grade of 0.57g/t gold and 1.14% copper. Underground development was 786m. Ore processed was 1,001kt at an average grade of 0.58g/t gold and 1.14% copper. Gold recovery of 79.9% and copper recovery of 94.9% was achieved with mill utilisation at 81.8%. Mill utilisation was negatively impacted in November due to a nine day major mill shut down.

FINANCIALS
Cash generation in the December quarter again highlighted the strength of Evolution’s asset base with operating mine cash flow of A$170.3 million. This was above the A$169.3 million achieved in the prior quarter despite the average achieved gold price being A$105/oz lower in the December 2016 quarter. Net mine cash flow post sustaining and major capital was A$102.1 million (Sep 2016 qtr: A$111.4 million).
Total Group gold sold was 198,782oz at an average gold price of A$1,603/oz (Sep 2016 qtr: 205,858oz at A$1,708/oz). Deliveries into the hedge book totalled 63,751oz at an average price of A$1,580/oz with the remaining 135,031oz of gold delivered on spot markets at an average price of A$1,631/oz. Gold sold for the quarter does not include Ernest Henry gold production of 14,257oz which is classified as inventory until sold as per the Offtake Agreement (refer Appendix 1 for details on Ernest Henry reporting). This gold will be delivered and sold during the March 2017 quarter.
Despite a lower average gold price for the quarter, all sites except Edna May were again cash positive after meeting their sustaining and major capital commitments. Cowal (A$45.7 million), Mungari (A$21.7 million) and Mt Carlton (A$22.6 million) generated the majority of the cash flow for the quarter. Mt Rawdon’s net mine cash flow of A$7.9 million was down on Sep quarter due to the lower gold price and planned higher capital, slightly offset by higher gold ounces sold for the quarter.
Ernest Henry made an initial contribution to the portfolio during the quarter with reporting commencing from 1 November 2016. Ernest Henry generated a net mine cash flow of A$1.6 million representing the sales of copper and silver production during the quarter, net of Evolution’s share of operating costs and sustaining capital. This has been booked as a receivable and does not include any revenue from the production of the 14,257 ounces of gold.

E42 Stage H, step-out drilling and E42 exploration diamond drilling program
Resource definition drilling as part of the E42 Stage H cutback feasibility study was completed ahead of time, under budget and delivered favourable results. A total of thirty-four diamond drill holes (21,982m) were completed during the period.
Work on the resource model, open pit optimisation and feasibility study on the Stage H cutback is well advanced and remains on track for recommendation to the Evolution Board in the March 2017 quarter.
Owing to the success of the Stage H drilling program, gated capital to continue step-out drilling to the southwest of the E42 pit was approved and commenced during the December quarter. Holes were collared 100m to 150m from the pit crest and will test for the continuation of mineralisation outside of the Stage H pit cutback. Preliminary intersections for this program are reported below. The step-out program is expected to be completed in the March quarter.

During the quarter, Evolution entered into a binding agreement with Newcrest Operations Limited (“Newcrest”), a wholly owned subsidiary of Newcrest Mining Limited, to acquire the Marsden copper-gold project. Evolution will make an upfront payment of A$3.0 million on completion of the acquisition and a further A$7.0 million payment contingent on a decision to mine within 10 years of the date of acquisition. The agreement is subject to conditions including governmental approval.
Marsden is a copper-gold porphyry deposit located immediately to the southeast of the Cowal gold mine. Marsden is the nearest known sizeable mineral deposit to the Cowal operation outside the Cowal tenement package and as such has strategic value to Evolution’s exploration activities in the region.
Mungari, Western Australia (100%)
Near mine exploration
Exploration drilling totalled 40,350m (477 holes) and included 8,386m diamond drilling, 10,054m reverse circulation (‘RC’) drilling and 21,910m aircore drilling. The majority of drilling was focussed at Frog’s Leg East and the Julius prospect in the Broads Dam project area.
In the Frog’s Leg East area, 1km east of the Frog’s Leg underground operation, 10 diamond and six RC holes were drilled to test the continuity of mineralisation intersected in previously reported drilling. All drill holes encountered laminated quartz veins and base metal sulphides which are important indicators of this mineralisation style across the Kundana camp. Best assays received to date included:
-
2.0m (1.8m etw) grading 8.4g/t Au from 107m (EVRC0028)
-
1.0m (0.9m etw) grading 12.0g/t Au from 47m (EVRC0029)
-
1.0m (0.9m etw) grading 10.1g/t Au from 88m (EVRC0044)
At Julius, five deep step-out diamond holes were completed to test the scale and continuity of mineralisation encountered in previous drilling. Best results included:
-
1.0m (0.9m etw) grading 105.0g/t Au from 439m (ZSRC043D)
-
3m (2.7m etw) grading 3.8g/t Au from 135m (ZSRC099)
Mineralisation at Julius has been identified on consecutive drill sections with a strike extension of 1,100m. Mineralisation is open to the south and will be tested by further drilling during the March quarter.

Resource definition drilling
At Frog’s Leg, infill drilling underground targeted Rocket South near the base of the mine and remnant mining opportunities in the Quartz Lode below the Frog’s Leg pit. Best results from the two areas included:
-
3.25m (2.85m etw) grading 14.67g/t Au from 71.75m (FLGC445)
-
11.20m (9.8m etw) grading 9.74g/t Au from 142.2m (FLGC450)
-
7m (6m etw) grading 8.97g/t Au from 68m (FLGC451A)
A total of 600m of RC and 499m of diamond drilling was completed at White Foil. Drilling targeted the White Foil South area below a recently recognised fault, which is interpreted to control high-grade mineralisation within the pit. A further three holes are planned during the March quarter to complete the program. The best intersection was:
- 17.3m (9m etw) grading 4.55g/t Au from 233.7m (WFRD024)
Regional Projects
Following ranking of the regional project pipeline in the September quarter, an aggressive resource definition drilling program commenced at seven projects. Up to six drill rigs undertook infill and step-out drilling at Kintore, Castle Hill (Mick Adam), Carbine North, Cutters Ridge, Burgundy, Red Dam and Backflip aiming to confirm and extend known mineralisation. Each project’s Mineral Resource is being updated and will be evaluated by open pit optimisation. The results will be used to rank the project pipeline. The objective is to guide and develop an optimal approach to advancing these targets to production opportunities.

Figure 3: Location map of Mungari regional projects
In the December 2015 resource statement the Castle Hill project was reported as Stages 1 – 3. These stages were based on a projected development sequence previously reported by Phoenix Gold. The project group contained numerous individual resource areas such as Kintore, Mick Adam and Kiora. To improve transparency, Evolution Mining will report the resources and exploration results based on independent resource areas. Kintore will be reported separately and Castle Hill will refer to the historical Mick Adam and Kiora resource area. Other projects also previously reported with Castle Hill will be reported independently. Thirty diamond drill holes for 5,201m, and 126 RC drill holes for 13,027m were drilled across these seven regional resource projects during the quarter. Main highlights from the program are discussed below
At Kintore, 74 RC and five diamond holes were completed targeting a significant extension to the Kintore West pit previously mined by Phoenix Gold. A blanket of supergene mineralisation occurs at the base of oxidation, approximately 30m below surface over widths of 1.0 to 5.0m. The best grades occur close to where primary shears intersect the base of oxidation.
Significant assays results returned during the quarter from Kintore included:
-
12m (9.6m etw) grading 7.15g/t Au from 128m (including 1m grading 79.5g/t Au) (KNTC001)
-
1m (0.8m etw) grading 30.2g/t Au from 79m (KNTC031)

At Castle Hill three diamond holes and six RC drill holes were completed during the quarter. These holes will be incorporated in the upcoming Mineral Resource estimate.
At Carbine North, 17 RC and three diamond holes were completed during the quarter. The program was completed to confirm gold grades predicted by the resource model which included a significant proportion of cross-over RC drilling from the late 1980s. Six fences of two to three RC holes on 40m centres were completed over a strike of 850m.
Mineralisation occurs in a supergene blanket situated 30m below surface and in two primary shear zones beneath the blanket. Best results included:
-
13m (11.1m etw) grading 1.51g/t Au from 71m, 10m (8.5m etw) grading 1.57g/t Au from 104m (CBNC004)

Cracow, Queensland (100%)
Resource Definition Drilling
A total of 15,446m of resource definition drilling was completed at Cracow. This comprised infill and extensional drilling at Coronation, with the northern limits of mineralisation confirmed to extend into Imperial. Drilling was also completed at Baz, Denmead, Killarney and Griffin.
Significant intersections returned at Coronation included:
-
7.05m (6.13m etw) grading 10.49g/t Au (CNU039)

Regional exploration
Exploration focussed on regional targets outside of the operating footprint in the Cracow Gold Field. Geological mapping and rock chip sampling were completed at the Walhalla and Valkyrie prospects, north and northwest of the Cracow mine respectively. Further work to refine drilling targets at both prospects will be completed in the March quarter.
Evaluation of an area southwest of Killarney was undertaken. Stratigraphic evidence collected to date supports the interpretation of a potentially prospective epithermal structure west of the existing drilling coverage.
Tennant Creek, Northern Territory (earning 65% in Stage 1)
Exploration activity during the quarter focussed on drilling targets within the Northern Project area. Approximately 5,000m of RC and diamond drilling was completed following up previously reported results at Edna Beryl and testing targets at Susan and Retsina prospects.
At Edna Beryl significant mineralisation was intersected below and to the immediate north of the current Tribute mine area and results are currently being compiled. Additional targets are expected along strike with a high-resolution gravity survey planned in February 2017. Drilling at Susan has downgraded the potential for a minable resource at the prospect. At Retsina, RC drilling intersected variably altered ironstone horizons below small surface exposures, and assays are pending.
Puhipuhi, New Zealand (100%)
Greenfield exploration
Initial diamond drilling program
Initial drilling was undertaken to test combined CSAMT geophysical and geochemical targets at the Puhipuhi epithermal gold-silver prospect. Four holes for 1,779m were completed in the December quarter. Drill results have returned anomalous gold and silver mineralisation in narrow vein and breccia zones developed in clayaltered sedimentary rocks.
Further information on all reported exploration results included in this report is provided in the Drill Hole Information Summary and JORC Code 2012 Table 1 presented in Appendix 2 of this report.

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.

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 navigational diamond core drilling. A fence of parent holes with up to 5 daughter holes wedged off using navigational (navi) steering were being drilled at time of reporting. Parent holes were designed on a nominal 50m spaced line with daughter holes designed to be at 50m spacings a target zones. Intent of drilling is to upgrade inferred and unclassified material in the existing model as well as add additional ounces. 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. 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. |

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. |

|---|---|---|
| Logging | Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. Whether logging is qualitative or quantitative in nature. Core (or costean, channel etc.) photography. The total length and percentage of the relevant intersections logged. |
All core intervals and RC chips are 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 clearly referenced in the 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. NQ core from the daughter directional holes was whole core sampled. 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 |

samples; CRM’s are submitted 1 in every 20 samples. The frequency of 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 Laboratoryis performing to anacceptablelevel. |
|
| 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. Gyro survey readings were also taken at roughly 100m intervals on parent holes to ensure accurate positioning and during navi cuts to achieve desired separation at target. 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 currentmine grid system |

Drill holes for the directional program were positioned on a 50m line spacing and navi cuts were steered and gyro’d to achieve a nominal 50m spacing at the target zone. All drilling is sampled at 1 m intervals down hole. |
| 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.

Diamond holes were positioned to optimise intersection angles, nominally SW-NE at 55 degree dip for Parent holes and 35-50 degrees for daughter holes. Conventional diamond drill holes were drilled in the same orientation. |
| 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 ALS Orange, PJ & NA Freighters are 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 withtheresults 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 and Barrick. External audits were conducted in 2003 by RMI and QCS Ltd. and in 2011 and 2014 review and validation was conducted by RPA. Minor validation errors associated with the migration of historic databases to Datashed were identified and remediated. Recent audits have found no significant issues withdatamanagement systems ordata quality. |

| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. If it is not known and only the downhole lengths are reported, there should be a clear statement to this effect (e.g. ‘downhole length, true width not known’) |
Mineralisation within the main E42 pit is bounded by large north-south trending structures; however it is has strong internal structural controls. A plunging lode has been identified in the SW of the main pit and had been targeted by this drilling and as such intercept angles are near perpendicular to the main mineralised body. All significant intercepts are reported as down hole intervals. |
|
| 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 |

Significant intercepts reported are only those areas where mineralisation was identified. A significant directional drilling program targeting an upgrade in resource classification and an increase in Ore Reserves was completed. This program consists of 10 parent holes with 5 daughter holes each for a total of 31,500 metres. A drilling program stepping back 50m and 100m beyond Stage H drilling commenced in September. At the time of reporting ~76% of this drilling had been completed. Holes in this report relating to this drilling include E42D1740, E42D1741, E42D1742, and E42D1745. Drill assay results returned during the quarter are presented in the table above with several holes still awaiting assay results at time of reporting.

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 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 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 0.3 to 1.3m. Diamond core from underground was predominantly whole core sampled, while 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.) |
RC sampling was completed using a 4.5” to 5.5” diameter face sampling hammer. Diamond holes from both surface and underground were predominantly wireline NQ2 (50.5mm) or |

HQ (63.5mm) holes. All diamond core from surface and selected underground holes were 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 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. |
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. All Exploration and selected Resource Definition diamond 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. |
| 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. |
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. A proportion of underground diamond core holes were half core sampled and the remaining core retained for further geological or metallurgical analysis 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 thegeologist’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 industrystandards. |

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 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 |

| Location of data points |
Accuracy and quality of surveys used to locate drillholes (collar and downhole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Specification of the grid system used. Quality and adequacy of topographic control. |
All surface drill holes 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. Underground down hole surveys consist of regular spaced digital single-shot borehole camera shots (generally 30m apart down hole), and digital electronic multi-shot surveys (generally 3m apart down hole). In instances where strong ground magnetics affect the accuracy of the measured azimuth reading, then these results are removed. 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. 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. |
Mineralisation at Frog’s Leg is hosted within a number of steeply dipping NNW-SSE structures that are vertical or dipping steeply (~80 degrees) to the west. Surface and underground drilling intersect the mineralisation at an angle to minimise bias. Mineralisation at White Foil is hosted within a brittle quartz gabbro unit. The gold is associated with quartz stockworks. Structural studies confirms the presence of two main vein sets at White Foil with a dominant moderately NNW dipping set (51º/346º dip and dip direction) and a secondary SSE dipping set (56º/174º dip and dip direction).. An identifiable systematic bias associated with drilling direction has not been established. The main strike to the gabbro unit is NNW-SSE and it plunges steeply towards the NNE. The predominant drill direction was to the SE. Surface holes and underground resource holes typically intersect at an angle to the mineralisation and there is no observed bias associated with drilling orientation. The relationship between the drilling orientation and the orientation of key mineralised structures at Mungari is not considered tohaveintroduced a sampling bias andisnot |

In a minority of instances on extreme edges at the Frog’s Leg deposit the drill angle is sub parallel with the lodes and does not intersect the width of the mineralisation. Resource Definition 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 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. |

Acknowledgment and appraisal of exploration by other parties. |
The initial discovery of Frog’s Leg was made by Mines and Resources Australia Ltd who was a precursor company to La Mancha Resources Australia Pty Ltd. The deposit was discovered in 2000 as a result of following up on regional anomalism identified through rotary air blast (RAB) and aircore drilling. La Mancha was acquired by Evolution in August 2015. At White Foil the initial anomaly was identified by Afmeco who found the Kopai trend which eventually included White Foil. The discovery was made in 1996 by Mines and Resources Australia who was a precursor company to La Mancha Resources Australia Pty Ltd. Placer Dome Ltd was a 49% joint venture partner during the first mining campaign in 2002-2003 Significant historical work has been performed across the Regional Tenement package by numerous parties since the original discovery of gold in the region c.1890. Recent exploration commenced during the 1970’s onwards and has included exploration forbasemetaland goldmineralisation. |
| Geology | Deposit type, geological setting and style of mineralisation. |
The Frog’s Leg deposit is located in the southern portion of the Kundana mining area, within the Achaean Norseman-Wiluna greenstone belt of the Eastern Goldfields Province. The Kundana gold deposits are structurally related to the Zuleika Shear Zone, a regional NNW-trending shear zone that juxtaposes the Ora Banda domain to the east and the Coolgardie domain to the west. The Frog’s Legdeposit is |

| located on the sheared contact between the porphyritic “cat rock” (regionally known as the Victorious Basalt) and volcaniclastic rocks of Black Flag Beds The White Foil gold deposit is a quartz stockwork hosted in a gabbro. The gabbro is differentiated broadly into a quartz-rich phase in the west. This quartz gabbro unit is the most hydrothermally altered unit and contains the bulk of the gold mineralisation. The White Foil deposit is bounded to the west by hangingwall volcaniclastic rocks. To the east mineralisation becomes irregular and uneconomic in the more melanocratic phase of gabbro. Mineralisation is controlled by sheeted systems of stockwork veining, which has imparted strong alteration and sulphidation to the quartz gabbro. The Castle Hill deposit is located in the western portion of the Mungari tenements and is structurally related to the Kunanulling Shear Zone and Kintore Tonalite. Mineralisation is related to sheeted vein sets within the attenuated southern tail of the Tonalite The Kintore Deposit is located in the western portion of the Mungari tenements and is structurally related to the Kunanulling Shear Zone and Kintore Tonalite. An ENE trending shear within the tonalite controls a moderate to steep south dipping set of mineralised veins. Alteration varies from hematite-epidote to sericite dominant. Gold is often observed as micronuggets in and around quartz veins The Carbine North deposit is located in the northern portion of the Mungari tenements and is structurally related to the Carbine Thrust, a linking structure between the Zuleika and Kunanulling Shear Zones. Geology dips to the north east and consists of ultramafic and mafic basalts and volcanoclastic sediements intercalated with narrow shale bands. Mineralisation occurs in three domains, as a sub-horizontal supergene horizon 30m below surface, and in two primary shears, one within the volcanoclastic sediments and the other on the contact between mafic and ultramafic basalt. Mineralisation is associated with quartz sulphide veining. The Cutters Ridge deposit is located in the southern portion of the Mungari tenements and on the western limb of the PowderSill Gabbro. Geologically, Cutters Ridge is a mirror image, albeit a smaller version, of the White Foil deposit. Gold is hosted within the quartz dolerite zone of the differentiated PowderSill Gabbro. 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 volcanoclastic 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. The Red Dam deposit is located in the northern portion of the Mungari tenements and is located on a linking shear between the Zuleika and Kunanulling Shear zones. Mineralisation occurs in quartz veining along lithological contacts close to the intersection with Cross-cutting D4 faults. The Backflip prospect in located in the Northern portion of the Mungari tenements close to the historic town of Grants Patch. Mineralisation is hosted on the Backflip Shear, a north-south trending fault/shear system with intense sericite alteration that runs through the Bent Tree Basalt. Mineralisation is associated with quartz sulphide veining within the shear zone. A north and south zone of mineralisation are offset by the E-W trending Comanci Fault. The Julius Prospect is located in the northern portion of the Mungari tenements and is structurally related to the Zuleika Shear Zone. Mineralisation is observed to occur within ductile shear zones associated with dolomite-sericite-sulphide alteration. |

Refer to Appendix for the drill hole information table |
| 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. At Frog’s Leg composite grades of > 3 g/t have been reported At White Foil, Julius, Frog’s Leg East and other regional properties composite grades >1 g/t have been reported 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. 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’) |
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. |

Mt Carlton
Mt Carlton Section 1 Sampling Techniques and Data
| Criteria | Explanation | Commentary |
|---|---|---|
| Sampling techniques |
Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as downhole gamma sondes, or 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 representivity 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 done this would be relatively simple (eg ‘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. Unusual commodities or mineralisation types (eg submarine nodules) |
Reported assay data for this report is based on PQ, HQ and NQ diameter core. PQ was drilled largely through weathered zones and broken ground of weak mineralisation then followed with HQ and NQ diamond core to end of hole. Oxidised core (PQ) is usually sampled using kitchen knife whiles competent core HQ and NQ size was cut with a diamond saw along orientation lines. Nominal sampling intervals for all core is 1m lengths. Shorter or longer core (<2m) sampling lengths occurs on occasions where adjustments are required to core loss, alteration or lithology changes. The length of each core recovered from a drill run is recorded and the percentage recovered calculated. Field core recovery records are validated at the coreshed prior to cutting and sampling. Bottom half of split core was preserved and the other half sent for analysis. This is done consistently to avoid sampling bias. A duplicate quarter core sample is taken for every 20thcore sample. Half core samples averaging 2-31/2kg along with quarter core samples are prepared and analysed at ALS Townsville facility. Weights of samples dried at 105OC are recorded and crushed to 6mm. Samples are split and excess bagged if crushed weight is greater than 3kg. LM5’s are used to pulverise samples to 85% passing 75um. A 200g pulp split is taken for analysis which comprise; a 50g charge fire assay with AA finish and ICP-AES for multi-element suite. |
| Drilling techniques | Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg 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 drilling was undertaken with PQ, HQ and NQ bits. Holes were usually started with PQ and completed with HQ or NQ on occasions due to poor ground conditions. Coring was by triple tube and all cores were oriented using Reflex Act RD2 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. |
Field recovery records for core are reconciled with driller’s depth blocks. Percentage core recovery is calculated and stored in a database along with Geotechnical records. Drillers are informed of the importance of core recovery, all necessary care is taken to ensure every drill run has maximum core recovered. Shot core runs were done in bad ground to ensure core loss is significantly minimised. Areas of poor core recovery were noted during logging. “CL” is marked on depth blocks denoting core loss. Intervals of core losses are considered during sampling and referenced when assessing assay data. No discernible relationship between core loss and grade has been identified. Mineralisation is hosted within fresh advance argillic rhyodacite unit where core recoveries are in excess of 90%. Bonanza gold grade occurs within feeder zones with fracture filled enargite and hydrothermal breccias veining cemented in silicic alteration overprinted by sulphur salts with random acid leached zones. Core loss sometimes occurs in the acid leach zones and sheared contacts bordering mafic dykes and rhyodacite. Drillers take great care drilling through such zones to minimise sample loss. Overall recovery is in excess of 90% and core loss is volumetricallyinsignificant. In weathered overlyinglithologywhere |

|---|---|---|
| oxidation has occurred between sheared lithology contacts, core loss is unavoidable but recovery is generally in excess of 85%. Mineralisation in the lithology overlying the rhyodacite is generally weak and therefore has less impact on modelled bonanza high grade. |
||
| 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. |
Geology logging is undertaken for all drill cores. Structural and geotechnical logging occurs for core only. Detailed logging is undertaken for the entire drillhole in domains of alteration, mineralisation and lithology. Densities of various lithological units, ASD and magnetic susceptibility data are captured as part of the logging process. Lithogeochemical samples are collected in areas where lithology units are not easily discernible. The logging process is appropriate for Mineral Resource estimates, mining and metallurgical studies. General logging data captured are; qualitative (descriptions of the various geological features and units) and quantitative (numbers representing alteration intensities, vein densities, rock mass quality and defect planes) Drill holes (All core) were logged as full core prior to photographing (dry and wet) and cutting. |
| 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. |
Core was cut using diamond core saw along orientation lines and sampled at nominal one metre intervals from the same side in the tray at all times. All core samples submitted to ALS, Townsville for analysis are half core except for duplicate core which is quarter core. The remaining half/quarter core is persevered in the tray for further test work or re-logging if required. Core sample preparation involves oven drying, coarse crushing to ~6mm followed by pulverisation of the entire sample (total prep) using LM5 grinding mills to a grind size 85% passing 75 micron. A 50g sub-sample is utilised for fire assay. Sample preparation and analysis follows industry best practise and appropriate for the mineralisation. Certified reference material along with blanks and field duplicates are inserted into sample stream along with the original samples. Standards, blanks and field duplicates cover 5% of sample volume to monitor sample preparation and the analytical process. The high sulphidation epithermal mineralisation at Mt Carlton occurs in zones of highly silicic altered hydrothermal breccias overprinted by several phases of sulfur salts containing bonanza gold grades and anomalous base-metal grades. Core sample size of 2-31/2kg sample length over 1m is suitable for the mineralisation type. The sample sizes are considered appropriate for the material sampled. It is believed that grain size bears no impact on sampled material. |
| 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 (ie lack of bias) and precision |
All core samples are analysed at ALS Townsville. Gold was analysed using 50g charge fire assay followed by AAS finish. Base metal and other elements are analysed using ICP-AES following a four acid digest. The analytical method used by ALS approaches total dissolution of high sulphidation epithermal mineral assemblages of the Mt Carlton deposit. The sample preparation and assay techniques meet industry best practise. Spectral data is collected consistently at a spot within a meter mark using short wave infrared spectrometer (ASD TerraSpec 4 Hi-Res). Data is processed using TerraSpec/TSG Pro software in the context of the project geology. The accuracy and spread of “Standard” data is acceptable within 2 standard deviations. Any outlier between the second and third standard deviation triggers an anomaly and is investigated. An entire batch is re-analysed when a sample plots outside three standard deviations. Blanks are acceptable within 10Xpractical detection limit, five samples preceding and following the outlier are re-analysed. The internal QAQC data of ALS is accessible online. The analytical system at ALS captures data at all stages of the sample preparation and analyticalprocess. The system minimiseshumanerrorand |

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. |
Significant intercepts calculation is based on a downhole intercept weighted length of 1m above a 0.35g/t cut-off of the resource model with an allowable internal dilution for intervals up to 2m. No top cuts have been applied in the calculation. Composite and internal significant values are stated for clarity. |

|---|---|---|
| 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. |
No metal equivalent values are used. |
|
| Relationship between 51ineralization 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’) |
Mt Carlton mineralisation generally trends NE and dips moderately to the west. Brecciated silica ledges which control bonanza lodes dips steeply to the west and plunges NE. These zones are discrete and discontinuous. Mineralised zones are based on interpreted geology and structural trends from drill hole data and pit mapping. Reported intervals are downhole widths as true widths are not currently known. An estimated true width (etw) is provided in the Drill Hole Information Summary appendix. |

Cracow Section 1 Sampling Techniques and Data
| Criteria | Explanation | Commentary |
|---|---|---|
| Sampling techniques | Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as downhole gamma sondes, or 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 representivity 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 done this would be relatively simple (eg ‘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. Unusual commodities or mineralisation types (eg submarine nodules) |
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. |
| Drilling techniques | Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face- sampling bit or other type, whether |
A combination of drilling techniques was used across the Cracow Lodes. Diamond NQ3 (standard) and LTK60 were the most commonly used. All of the holes reported were drilled from underground and none of the holes reported were orientated. |

| core is oriented and if so, by what method, etc). |
||
| 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. |
| Sub-sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. For all sample types, the nature, quality and appropriateness of the sample preparation technique. Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. Whether sample sizes are appropriate to the grain size of the material being sampled. |
All 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 crushing and pulverising stages, with no bias found at any sub- sampling stage. The sample size collected is considered to be appropriate for the size and characteristic ofthe goldmineralisationbeing |

| 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 (ie lack of bias) and precision have been established. |
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. |
| 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. |
Underground drill-hole positions were determined by traversing, using Leica TS15 Viva survey instrument (theodolite) in the local Klondyke mine grid. Down-hole surveys were captured by an Eastman camera for older holes and a Reflex camera on recent holes. The mine co-ordinate system at Cracow is named the Klondyke Mine Grid, which transforms to MGA94 Grid and was created and maintained by onsite registered surveyors. |
| 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 |
Drill hole exploration results are not being reported. Sample spacing and distribution was deemed sufficient for resource estimation. Spacing and distribution varied a range of drill patterns: 20x20, 40x40x and 80x80. The sample spacing required for the resource category of each ore body is unique and may not fit the idealised spacing indicated above. |

| classifications applied. Whether sample compositing has been applied. |
All datasets were composited prior to estimation. The most frequent interval length was 1 metre, particularly inside and around mineralised zones. 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. |

| 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 | ||||||||
