OVERVIEW
Group gold production for the September 2016 quarter was 205,307 ounces (Jun qtr: 216,644oz). Average C1 cash cost was A$753/oz (Jun qtr: A$732/oz) and AISC[1] was A$1,060/oz (Jun qtr: A$1,117/oz). Using the average AUD:USD exchange rate for the quarter of 0.7585, Evolution’s Group C1 cash cost equated to US$571/oz and Group AISC to US$804/oz.
In the September 2016 quarter Evolution delivered operating mine cash flow of A$169.3 million and net mine cash flow, post all sustaining and major capital, of A$111.4 million (Jun qtr: operating cash flow A$184.2 million; net mine cash flow A$119.5 million). This strong operational cash flow allowed Evolution to make debt repayments totalling A$90.0 million during the quarter.
As at 30 September 2016, outstanding debt comprised of A$75.0 million in the Senior Secured Syndicated Revolver Facility and A$120.0 million in the Senior Secured Syndicated Term Facility B. The Group cash balance at 30 September 2016 was A$435.3 million.
Evolution completed a A$401.6 million equity entitlement offer in September 2016. These funds, together with cash and a new A$475.0 million Senior Secured Syndicated Term Facility D, will be used to pay the A$880.0 million acquisition cost to Glencore on completion of the Ernest Henry transaction.
Evolution made its seventh consecutive dividend payment during the quarter. In June 2016 Evolution increased its dividend policy from 2% to 4% of revenue which was effective for the FY16 final dividend. Cash dividends totalling A$25.6 million (net of the DRP) were returned to shareholders in September.
Results of the Cowal definition drilling program are continuing to confirm grade distribution in the Stage H pit design, increase resource confidence and extend the resource beyond the current pit limits.
At Mungari, a high-grade, laminated vein was intersected in a diamond hole 1km east of Frog’s Leg along with a new zone of mineralisation identified at the Julius prospect 1.5km south of Johnson’s Rest.
Recent drilling at Mt Carlton has verified continuity of high-grade mineralisation beneath the pit. The new results will be used to evaluate a range of pit extension and underground mining options.
On 24 August 2016 Evolution announced the acquisition of an economic interest in the Ernest Henry mine – a large scale, long life, copper-gold asset operated by Glencore plc. Evolution’s economic interest consists of:
-
100% of gold and 30% of copper and silver produced during the current 11 year Life of Mine plan
-
30% contribution to current Life of Mine production costs
-
49% interest in all copper, gold and silver production beyond current Life of Mine plan
-
An agreement to work together to establish a regional exploration joint venture
If Evolution had owned this asset in FY16 it would have delivered pro forma production of 88,000 ounces of gold at an AISC of A$(59) per ounce and a net mine cash flow of A$142.0 million. The transaction remains subject to Foreign Investment Review Board approval and is expected to close in the December 2016 quarter.
The sale of the Pajingo gold mine and surrounding exploration tenements to Minjar Gold was successfully completed on 1 September 2016. Evolution has now received the A$41.9 million upfront cash payment from Minjar Gold. The sale agreement also included a 1% NSR (net smelter return) royalty of up to A$10.0 million payable to an Evolution subsidiary for future gold production above 130,000 ounces from Pajingo.

OPERATIONS
Cowal, New South Wales (100%)
Cowal produced 64,032oz of gold in the September quarter at a C1 cash cost of A$687/oz and AISC of A$907/oz (Jun 2016 qtr: 65,926oz, C1 A$612/oz and AISC A$915/oz).
Mine operating cash flow for the quarter was A$63.7 million. Cowal delivered a net mine cash flow of A$51.5 million (Jun 2016 qtr: A$42.2 million), post sustaining capital of A$12.2 million.
Two shutdowns occurred in the processing plant during the quarter. A shutdown in September was brought forward from October due to weather conditions temporarily impacting operations.
Mining activities focussed on the Stage G cutback to a current operating level of 921mRL.
E42 resource definition drilling in support of the Stage H cutback feasibility study is progressing well and delivering strong results. This program was the major contributor to sustaining capital expenditure during the quarter.
Late in the quarter the NSW Central West region was impacted by a severe weather event which caused flooding in the local communities of Forbes and Condobolin. Evolution deployed Cowal’s Emergency Response Team and additional crews and vehicles to assist the SES in mitigating the impact on these communities. This weather event had no material impact on Cowal production.
Mungari, Western Australia (100%)
Mungari produced 38,295oz of gold in the September quarter at a C1 cash cost of A$897/oz and AISC of A$1,081/oz (June 2015 qtr: 43,448oz, C1 A$643/oz and AISC A$944/oz).
Mine operating cash flow for the quarter was A$30.0 million. Mungari delivered a net mine cash flow of A$21.0 million, post sustaining capital and major capital of A$8.9 million.
The Frog’s Leg underground mine produced 176kt at an average grade of 4.25g/t Au. The lower grade was due to the timing of access to the highgrade stopes at Mist and lower than anticipated grade in various stoping areas mined during the quarter. Grades will increase during the December quarter as scheduled production accesses higher grade stopes.
Productivity improvements saw development metres increase by 24% compared to the prior quarter with no change in equipment or resources.
Mining of the White Foil open pit focussed on Stage 2b and Stage 3. Total open pit material movement of 2.6Mt was on plan despite the significant winter rain impact during July and August. In the month of September mining costs per tonne were 9% lower than the FY16 average. The introduction of larger 785t trucks, the completion of Stage 3 setup works and expected better weather should see unit mining rates continue to improve in the December quarter.
The plant processed 438kt during the quarter at an average recovery rate of 91.7%. Lower recovery rates were predominantly due to paste dilution and lower feed grade.

OPERATIONS
Mt Carlton, Queensland (100%)
Mt Carlton produced of 25,544oz of payable gold contained in 13,056 dry metric tonnes (dmt) of gold concentrate. Concentrate shipments for the September quarter were 11,260dmt across six shipments. A total of 199,802 tonnes of V2 ore grading 5.36g/t Au was treated during the quarter.
Costs remain low with C1 cash costs of A$323/oz and an AISC of A$779/oz (Jun 2016 qtr: C1 A$531/oz, AISC A$917/oz).
Mine operating cash flow for the quarter was A$25.5 million. Mt Carlton delivered a net mine cash flow of A$16.5 million, post sustaining capital and major capital of A$9.0 million.
A 2.5m lift on the tailings storage facility was completed during the quarter. Good progress has been made on the gravity recovery gold circuit with commissioning expected in the March 2017 quarter.
Mining of the Stage 2 pit was completed during the quarter. The December quarter will see accelerated mining of the Stage 3 pit to allow access to high-grade ore in the second half of FY17.
Resource definition drilling at Mt Carlton has verified continuity of high grade mineralisation beneath the V2 pit. The new results will be used to evaluate a range of pit extension and underground mining options.

Mt Rawdon, Queensland (100%)
Mt Rawdon produced 24,878oz of gold in the September quarter at a C1 cash cost of A$530/oz and AISC of A$764/oz (Jun 2016 qtr: 22,035oz, cash cost A$679/oz, AISC A$1,082/oz).
Mine operating cash flow for the quarter was A$19.3 million. Mt Rawdon delivered a net mine cash flow of A$10.5 million, post sustaining capital and major capital of A$8.8 million.
The lower costs and increased cash flow represents a significant turnaround for Mt Rawdon predominantly due to a declining strip ratio and increased grades.
Mining activities were focussed on the continuation of exposing Stage 4 ore and the completion of Stage 3. The ore extracted from Stage 4 provided the majority of the mill feed and continues to reconcile positively against the resource model.
Total ore mined of 1.29Mt at an average grade of 0.87g/t Au provided capacity during the September quarter to stockpile the lower grade ore. The increased ore stockpiles and completion of Stage 3 will provide optionality during the upcoming wet season.
In the December quarter, work will focus on waste and ore movements from Stage 4 western wall while supplying ore to the mill from Stage 4 north. This is expected to increase the operation’s ore blending capacity and enable consistent mill feed.

OPERATIONS
Edna May, Western Australia (100%)
Gold production of 20,012oz was achieved in the September quarter at a C1 cash cost of A$1,327/oz and AISC of A$1,472/oz (Jun 2016 qtr: 17,895oz, C1 cash cost A$1,516/oz, AISC A$1,554/oz).
Costs remained unacceptably high during the September quarter. The lower material movement in FY16 due to weather events and mine scheduling issues continued to impact performance. A new site general manager has been appointed and a full review of the operation is being undertaken.
Mine operating cash flow for the quarter was A$5.3 million. Edna May delivered a net mine cash flow of A$0.1 million, post sustaining capital and major capital of A$5.2 million.
Mining was focussed on the Stage 2 cutback leading to an increase in tonnes mined in the September quarter. Mined grade of 1.17g/t was 30% higher than the previous quarter as mining progressed into the base of the original Stage 1 pit.
The development of the underground portal has been successfully completed and has broken through into the existing decline. By the end of September approximately 50m of decline had been rehabilitated.
The quarter included a five day shutdown in July to change out steel linings in the SAG Mill and a one day shutdown in September to change out SAG Mill lifters.
Pajingo, Queensland (100%)
The sale of Pajingo was completed on 1 September 2016. During the 62 days of the September quarter still under Evolution ownership Pajingo produced 10,991oz of gold at a C1 cash cost of A$897/oz and an AISC of A$1,422/oz.
Cracow, Queensland (100%)
Cracow produced 21,554oz of gold in the September quarter at a C1 cash cost of A$856/oz, and AISC of A$1,253/oz (June 2016 qtr: 21,281oz, C1 A$877/oz, AISC A$1,366/oz).
140kt of ore was processed at an average grade of 5.11g/t Au. Gold recovery was 93.8% with plant utilisation of 99.1%.
Cracow has now operated for 37 consecutive months without a lost time injury – a significant safety achievement.
Mine operating cash flow for the quarter was A$18.0 million. Cracow delivered a net mine cash flow of A$10.7 million, post sustaining capital and major capital of A$7.3 million.
The increase in AISC in the September quarter related to capital expenditure on mobile equipment rebuilds, a TSF lift, increased resource definition drilling and the Fine Grind Mill project.
A total of 127kt of ore was mined at an average grade of 5.36g/t Au. Primary ore sources were Kilkenny, Empire and Klondyke ore bodies.
Operating development of 312m and capital development of 433m were achieved during the quarter. Development focussed on the Coronation and the Griffin deposits. A drill platform for testing the Baz and Killarney deposits was completed. Stoping and production drilling were a priority to establish the Kilkenny transverse stopes and the Empire 1874 stope.

The September quarter again highlighted the strength of Evolution’s cash generating asset base with operating mine cash flow of A$169.3 million (June 2016 qtr: A$184.2 million) and net mine cash flow of A$111.4 million (Jun 2016 qtr: A$119.5 million).
Total Group gold sold was 205,858oz at an average price of A$1,708/oz (June 2016 qtr: 226,558oz at A$1,666/oz). Deliveries into the hedge book totalled 63,751oz at an average price of A$1,576/oz with the remaining 142,107oz of gold delivered on the spot market at an average price of A$1,760/oz.
All sites were again cash positive after meeting their sustaining and major capital. Cowal net mine cash flow of A$51.5 million was just below its quarterly record while Mungari (A$21.0 million) and Mt Carlton (A$16.5 million) also contributed strongly. Mt Rawdon increased both operating (A$19.3 million) and net mine cash flow (A$10.5 million) on the back of higher production and lower sustaining capital.

| September 16 Quarter | 169.3 | (34.6) | (23.2) | 111.4 |
- Major Projects Capital includes 100% of the UG mine development capital
Total capital expenditure for the quarter of A$57.9 million was in line with plan (Jun 2016 qtr: A$64.7 million). The main capital projects included: Cowal resource definition drilling (A$7.3 million); tailings storage facility lift at Mt Carlton (A$5.0 million); Edna May underground mine project (A$2.8 million); capital waste stripping or development at Mt Rawdon (A$5.7 million), Edna May (A$1.7 million), Mungari (A$1.6 million stripping, A$5.6M underground development), Cracow (A$2.4 million) and Pajingo (A$3.6M); and purchase of new equipment at Cracow (A$1.6M).
Discovery expenditure in the quarter totalled A$5.9 million (Jun 2016 qtr: A$10.6 million). This decrease reflects lower planned activity at Puhipuhi, and lower expenditure at Pajingo and Wirralie following the divestment of these assets during the quarter. Corporate administration costs for the quarter were A$6.1 million (Jun 2016 qtr: A$8.9 million) with the June quarter containing a number of financial year-end charges and adjustments.
The strong net mine cash flow and proceeds from the sale of Pajingo was directed towards continued debt reduction. The Company made debt repayments totalling A$90.0 million during the quarter.
Evolution paid a final dividend for the 2016 financial year of A$29.4 million (A$25.6 million net cash outflow after DRP) which reflected the new dividend policy announced in June 2016 which doubled the payout ratio to 4% of revenue.
During the quarter Evolution successfully completed an equity raising of A$401.6 million via a fully underwritten accelerated renounceable entitlement offer. The proceeds for the equity raising will be used, in conjunction with a new debt facility, to fund the acquisition of an economic interest in Ernest Henry.
At 30 September 2016 the gross debt outstanding under the Senior Secured Syndicated Revolving and Term Facility was A$195.0 million. This is comprised of A$75.0 million in the Senior Secured Syndicated Revolver

CORPORATE
Facility and A$120.0 million in the Senior Secured Syndicated Term Facility B. The undrawn amount of the Senior Secured Syndicated Revolver Facility increased to A$225.0 million.
As a part of the Ernest Henry transaction Evolution has entered into a new Senior Secured Syndicated Term Facility D for A$475.0 million over a period of five years to October 2021. The Company finalised terms and executed the agreements for this new facility before the end of the September. Based on the Company outlook, the final amount of this new term facility is A$475.0 million which is A$25.0 million lower than the amount underwritten by the banks at the time of the announcement of the Ernest Henry transaction.
The amortisation profiles of the two Senior Secured Syndicated Term Facilities are as shown below.

Debt repayment obligations for the remainder of FY17 amount to only A$30.0 million. Evolution remains focussed on reducing the Company’s debt profile. This is evidenced by the repayment of A$412.0 million of debt in the past 13 months.
The balance sheet and debt repayment commitments are supported by Evolution’s hedge book. As at 30 September 2016 the hedge book stood at 643,238oz at an average price of A$1,628/oz.
The Group cash balance at 30 September 2016 was A$435.3 million (30 June 2016: A$17.3 million). The table below shows the movement of cash for the September quarter. The acquisition and integration costs in the September quarter mainly relate to legal, accounting and ASX fees for the Pajingo disposal and the agreement to acquire an economic interest in Ernest Henry.

EXPLORATION
Exploration highlights
-
Dr Glen Masterman, VP Discovery and Chief Geologist, commenced employment in August 2016
-
Results of the Cowal resource definition drilling program are continuing to confirm grade distribution in the Stage H pit design, increase resource confidence and extend the resource beyond the pit limits. New zones of mineralisation have been intersected to the south-west of E42 and outside of the A$1800/oz resource limits
-
At Mungari, a high-grade, laminated vein was intersected in a diamond hole 1km east of Frog’s Leg. The new vein shares characteristics with the Raleigh deposit (further north). Work is ongoing to understand the significance of the results
-
Drilling at Mungari regional tenements identified a new zone of mineralisation at the Julius prospect 1.5km south of Johnson’s Rest
-
Recent drilling at Mt Carlton has confirmed continuity of high-grade mineralisation beneath the V2 pit. The new results will be used to evaluate a range of pit extension and underground mining options

Near mine exploration
E42 Stage H resource definition diamond and RC drilling program
Thirty nine diamond drill holes (30,997m) and six Reverse Circulation (RC) holes (1,560m) were completed as part of the E42 Stage H resource definition program and targeted mineralisation below the south-west wall. The program’s objective was to increase the resource classification to an Indicated Mineral Resource and the Ore Reserves inside the Stage H pit design. The diamond holes included five parent holes and 34 daughter (wedge) holes. Since commencement of the Stage H drilling program, a total of 83 RC and diamond holes for 43,000m (95% of program) have been drilled to the end of the September quarter.
Infill drill results have confirmed the continuity of mineralisation within the Stage H cutback design. Step-out drill holes have intersected new zones of mineralisation which extend the limits of mineralisation to the southwest of E42. The drill holes have intersected broad zones of mineralisation with robust grades. The occurrence of high-grade intercepts indicates the potential for an increase in the grade of the current Mineral Resource estimate. Mineralisation remains open down plunge.
New significant intercepts included[1] :
-
71m grading 6.92g/t Au from 572m (E42D1711F)
-
13m grading 3.70g/t Au from 755m (E42D1713B)
-
20m grading 3.33g/t Au from 722m (E42D1715)
-
52m grading 4.63g/t Au from 708m (E42D1717)
Previously reported intercepts from the quarter included[2] :
-
62m grading 2.16g/t Au from 530m (E42D1711D)
-
41m grading 6.46g/t Au from 583m (E42D1712)
-
110m grading 1.43g/t Au from 704m (E42D1712A)
-
14m grading 8.09g/t Au from 610m (E42D1713A)
-
40m grading 2.76g/t Au from 485m (E42D1714)
Stage H diamond drilling is planned to conclude in the December quarter and the resource model will be updated to incorporate these results early in 2017. Due to the success of the program, step-out drilling commenced in late September. Holes are being collared between 100m and 150m south-west of the pit crest. The intent of the six-hole program is to extend the E42 Mineral Resource down plunge. A deep exploration hole is also planned to be drilled in the December quarter up to 300m from the pit crest. The aim is to test the continuity and extent of the E42 mineralised system. If successful, further infill and step-out drilling will be undertaken throughout H2 FY17.
- Reported intervals reported in this release are down hole widths as true widths are not currently known. An estimated true width (etw) is provided where possible
- Full details of these exploration results are provided in the report entitled “Cowal E42 Drilling Update” released to the ASX on 12 September 2016 and are available to view at www.asx.com.au

Mungari, Western Australia (100%)
Near mine exploration
Exploration drilling totalled 167 holes for 22,724m across the Mungari tenure and included diamond, RC and aircore drilling. The majority of drilling was undertaken at Johnson’s Rest/Broads Dam area, with additional targets tested in the Park Dam project area (1km east of the Frog’s Leg mine) and Area 11 located along the Kunanalling trend (acquired as part of the Phoenix Gold transaction[1] ).
In the Park Dam area, two diamond holes were drilled to test an interpreted north-south striking structure named Frog’s Leg East. Both drill holes encountered laminated quartz veins and base metal sulphide minerals, analogous to the mineralisation style seen at the Raleigh deposit. Gold mineralisation was intersected in both holes and significant intersections included:
-
2.2m (2.0m etw) grading 5.8g/t Au from 150.7m (PDDD0014)
-
0.4m (0.4m etw) grading 34.3g/t Au from 300.9m (PDDD0014)
-
3.0m (2.7m etw) grading 1.4g/t Au from 305.0m (PDDD0014)
==> picture [391 x 196] intentionally omitted <==
Figure 5: Map showing location of Frog’s Leg East and the collar position of holes PDDD0013 & PDDD0014
Ground magnetics and gravity is planned to sharpen targeting of the follow-up drilling. The aim is to understand if results in holes PDDD0014 are potentially indicative of a new high-grade vein in the Mungari camp.
At Johnson’s Rest, consolidation of drilling data and geological modelling of results commenced. Deeper drilling is planned for the December quarter which will be incorporated into the geological model with the objective of delivering a Mineral Resource model for economic evaluation.
Follow up drilling from the framework program in the June quarter 2016 defined a new target called Julius. A total of 15 holes have defined a zone of anomalous mineralisation 950m long (Figure 6). Mineralisation is open to the south and at depth and will be followed up in the December quarter. Significant intersections at Julius included:
-
16m (14.2m etw) grading 3.5g/t Au from 94m (ZSRC096)
-
5m (4.5m etw) grading 7.4g/t Au from 73m (ZSRC097)

Cracow, Queensland (100%)
Regional exploration
A total of 2,609m of drilling was completed at Cracow, testing seismic targets within the Phoenix South Corridor and on the southern 2D2R seismic line.
Drill testing along the southern 2D2R seismic line concluded in July, with the completion of KRC156. Drilling intersected hydrothermal alteration and anomalous gold and associated pathfinder elements associated with an important fault structure. Further work will be completed to understand the significance of these results.
Regional exploration activities were ongoing, with structural mapping and rock chip sampling completed in the Cracow Creek – Buffel Hill structural corridor. A soil sampling and mapping program was completed at the Boughyard prospect. The focus in Q2 FY2017 will be on reconnaissance mapping and geochemical sampling in the southern and northern extents of the Cracow tenement.
Resource Definition Drilling
A total of 8,580m of resource definition drilling was completed at Coronation, Baz and Killarney. The infill drilling at Coronation confirmed the grade continuity and also identified that mineralisation is not closed off to the north of Zone 10 (Figure 9). Activity next quarter will focus on infill and extensional drilling at Coronation and drill testing at the Killarney, Baz and Denmead areas.

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 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. |
|
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 |

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.

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. |

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 volumetrically insignificant. In weathered overlying lithology where 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-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 have been established. |
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 analytical process. The system minimises human error and ensures high data integrity. ALS participates in an international “Round Robin” QAQC program to ensure best industry practice is maintained. Based on quality assurance and quality control acceptable performance, assay data is suitable for use in Mineral Resource estimation. |
| 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 |
Significant mineralisation intercepts are verified by other geologists within the company. There were no twinned holes drilled. Data documentation, verification and validation are conducted in accordance with Evolution’s Data Storage Standard Operating Procedure. Logging is undertaken in significant detail for entire drillhole in domains of alteration, mineralisation and lithology. Data validation is conducted by the Project Geologist prior to uploading into the Database. Digital copies of logs are kept in dedicated folders on the Company server and backed up regularly. Audit trail of all changes that occur in the Database can be tracked. No adjustment or calibrations were made to any assay data used in this report. |

Exploration within the Mt Carlton EPM’s and ML10343 commenced in the 1970’s, with BHP, Ashton Mining, MIM exploration and others exploring the Capsize Range area within the current EPM10164 for porphyry copper and epithermal styles of mineralisation. In 2006, Conquest Mining discovered the V2 high sulphidation epithermal Au-Cu deposit, and Ag rich A39 deposit, with follow up work within the ML10343. |
| Geology | Deposit type, geological setting and style of mineralisation. |
The Mt Carlton high sulphidation deposit is located in the Early Permian Lizzie Creek. Mineralisaton is hosted within porphyritic rhyodacite which underlay a package of andesite lavas and fragmental volcanics. Basaltic to andesitic dykes crosscut mineralisation and mirror pre-existing structures. Gold mineralisation at V2 is associated with enargite–tennantite copper and silver minerals. |
| Drill hole Information |
A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drillholes: o easting and northing of the drillhole collar o elevation or RL of the drillhole collar o dip and azimuth of the hole o downhole length and interception depth o hole length. If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the _case. _ |
Drill hole information is provided in the Drill hole information summary table, provided in the appendix. |
| 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. |
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. 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’) |
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 drillhole 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. |

| 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 | ||||||
| of the Cracow Joint Venture. 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 and style of |
type, geological setting 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. | |||||||

| 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. |
|
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. |
|
| Where aggregate intercepts |
| No metal equivalent values are used. | ||
| incorporate short lengths of high | ||||
| grade results and longer lengths of | ||||
| low grade results, the procedure | ||||
| used for such aggregation should be | ||||

| such aggregations should be shown | ||||
| in detail. | ||||
| The assumptions used for any | ||||
| reporting of metal equivalent values | ||||
| should be clearly stated. | ||||
| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. |
