OVERVIEW
Group total recordable injury frequency rate at quarter end was 6.3. In FY18 there is an ongoing focus on improving the safety culture within the business. Work was undertaken during the quarter to improve the quality of incident investigations.
Group gold production for the March 2018 quarter was 191,474 ounces (Dec qtr: 186,488oz) at a record low AISC of A$768/oz (Dec qtr: A$784/oz). Using the average AUD:USD exchange rate for the quarter of 0.7863, Group AISC equated to US$604/oz – ranking Evolution as one of the lowest cost gold producers in the world. June 2018 quarter gold production is expected to be similar to the March 2018 quarter.
Evolution delivered operating mine cash flow of A$174.8 million. (Dec qtr: A$204.7M) and net mine cash flow, post all capital, of A$111.4 million (Sep qtr: A$134.2M). Group capital expenditure was A$63.4 million (Dec qtr: A$70.5M).

Evolution successfully renewed the Company’s revolver and performance bond facilities through until July 2021 for A$350.0 million and A$175.0 million respectively. At the same time, the Company reprofiled the amortisation of the Senior Syndicated Term Facility. The expiry of this facility remains unchanged at October 2021. The next repayment is now not due until September 2018. The renewal of the debt facilities has resulted in a saving of approximately A$6.0 million over the term.

Mt Carlton, Queensland (100%)
Mt Carlton produced 25,850oz of payable gold contained in 16,111 dry metric tonnes (dmt) of gold concentrate and 6,560oz in gold doré (Dec qtr: 29,927oz, 17,541dmt and 6,123oz gold doré). Low costs continue to be achieved with an AISC of A$445/oz (Dec qtr: A$493/oz). TRIFR reduced from 8.3 to 4.1.
Operating cash flow of A$21.5 million and net mine cash flow of A$16.1 million (Dec qtr: A$33.7 million), was generated post sustaining and major capital of A$4.5 million.
Cash flow was negatively impacted by delayed shipments of concentrate due to timing of shipments around Chinese New Year and heavy rain restricting site access late in the quarter. Gold sold of 19,701oz and copper sold of 384t was significantly less than production (25,850oz Au, 618t Cu). Larger shipments will occur in the June 2018 quarter to catch up with production.
A total of 195,231 tonnes of V2 ore grading 5.23 g/t gold was treated. Processing plant recoveries were 90.9%.
Mt Rawdon, Queensland (100%)
Mt Rawdon had a strong quarter producing 30,625oz of gold at an AISC of A$536/oz (Dec qtr: 21,418oz, AISC A$1,056/oz). TRIFR increased from 3.5 to 5.2.
Mine operating cash flow for the quarter was A$18.6 million. Mt Rawdon delivered net mine cash flow of A$15.9 million (Sep qtr: A$3.8 million), post sustaining capital and major capital of A$2.7million.
Mining activities were focussed on sourcing ore from the lower northern and western benches of the open pit.
Total ore mined was 1,378kt at an average grade of 1.10g/t gold. The plant processed 796kt at an average head grade of 1.34g/t gold.
In the June 2018 quarter, ore will primarily be sourced from higher-grade zones of Stage 4 western and lower benches.
Production is expected to be more than 25,000 ounces in the June 2018 quarter however Mt Rawdon’s FY18 production will likely be below the guidance range of 105,000 – 115,000 ounces.
Mining was focused on the Stage 3b cutback and the new Southern ramp construction.
The gravity circuit produced 6,560oz of gold doré (Dec qtr: 6,123oz). Optimisation work on this circuit is ongoing.
The Underground / Stage 4 pit Feasibility Study continued during the quarter.
Mt Carlton is expected to deliver FY18 gold production above the top end of the 100,000 – 110,000 ounces guidance range while AISC is expected to be significantly below the bottom end of the A$680 – A$730/oz guidance range.

Exploration highlights
-
Cowal – Mineral Resource update incorporated full year drilling results and delivered an 816,000oz addition at Galway Regal E46 (GRE46) Underground and at E41 and GRE46 open pits. Work programs in FY19 will aim to further delineate extensions of these resources along strike and at depth. Definition drilling is also planned to confirm grade continuity and understand geologic controls on grade distribution to support further classification upgrades. Step out results at E41 West and the GRE46 Underground continue to reinforce growth opportunities across near-mine satellite targets
-
Mungari – full results were received for definition drilling at the White Foil Underground target with new data incorporated in the December 2017 Mineral Resources and Ore Reserves update. Development commenced to extend the Frog’s Leg decline with the aim of establishing an underground drilling position to test extensions of the Frog’s Leg vein structure well below the base of the deepest workings
Cowal, New South Wales (100%)
Drilling continued at Cowal with 16 holes completed for over 7,800m between E41 West and GRE46. Air core drilling commenced in February on the East Girral project located 15km west of E42. Eighty-two holes were completed (6,862m) targeting structurally controlled gold mineralisation. The remaining 33 holes will be completed in April with full results expected by the end of the June 2018 quarter.
E41 West
Diamond drilling targeted extensions along strike and down dip of mineralisation delineated in previous drilling. The results identified potential for a structurally controlled style of mineralisation which has the potential to enhance grades at E41 West.
A significant number of assays are still pending, however the best intersections received to date include:
-
22m (8.4m etw) grading 1.1g/t Au from 176m and 19m (8.0m etw) grading 4.38g/t Au from 295m (E41D2811)
-
55m (24.8m etw) grading 1.15g/t Au from 153m (E41D2810)
The next phase of work at E41 West will include both infill and step out drilling, updating the 3D structural and lithological models along with detailed ground gravity aimed at mapping the distribution of important geological elements believed to influence mineralisation.

Mungari, Western Australia (100%)
Exploration
Over 27,000m of drilling was completed on 17 exploration targets across the Mungari land position.
New results from reverse circulation (RC) drilling at the Perimeter prospect (50km northwest of the Mungari process plant) indicate the presence of an 800m long corridor hosting mineralisation in narrow sheeted and stockwork quartz veins. Best results included 12m at 3.83g/t Au from 159m (EVRC0329) and 11m at 2.32g/t Au from 90m (EVRC0328). Drilling will continue in the June 2018 quarter to delineate the full extent of mineralisation north, south and beneath existing drilling.
Infill drilling was completed at the Scottish Archer prospect targeting the lithological contact between the Bent Tree and Victorious basalt units. The results indicate the presence of a 2 – 6m wide zone of mineralisation. Follow-up drilling is planned to further test potential extensions at depth.
Aircore drilling was completed at Red Dam South targeting structure parallel with the nearby Red Dam deposit. Anomalous gold extends for over one kilometre and may represent an oxide gold resource opportunity. Additional drilling is planned for early in FY19.
Evolution elected not to complete the earn in on the Binduli JV with Intermin Resources. As such the management of the tenements reverts back to Intermin in April 2018.

South Gawler, South Australia (earning up to 80%)
The first phase of work was completed at the South Gawler project including a detailed gravity survey, geochemical analysis of >1,000 surface samples and new mapping to constrain distribution of ironstone occurrences considered to be most indicative of a potential iron-oxide copper-gold (IOCG) target. Based on results of the work, Evolution has determined there is insufficient evidence to support the presence of an IOCG target of adequate size in the selected area. Evolution will not be advancing the project and has elected to exit the joint venture with Menninnie Metals.

Mineral Resources and Ore Reserves
Evolution today announced the outcome of its annual Mineral Resource and Ore Reserve estimates (refer to ASX release “Annual Mineral Resources and Ore Reserves Statement” dated 19 April 2018).
Evolution is committed to building a sustainable business that prospers through the cycle and has therefore used an unchanged and conservative gold price assumption of A$1,350 per ounce (US$1,050/oz) and a copper price assumption of A$6,000 per tonne (US$4,680) to estimate Group Ore Reserves.
Gold Mineral Resources increased by 68,000 ounces to 14.24 million ounces after accounting for mining depletion of 842,000 ounces and divestment of 848,000 ounces at Edna May. The largest offset was due to resource extensions at Cowal of 1.04 million ounces. Copper Mineral Resources decreased 88,000 tonnes to 946,000 tonnes after accounting for mining depletion.
Gold Ore Reserves increased by 58,000 ounces to 7.05 million ounces after accounting for mining depletion of 842,000 ounces and divestment of 426,000 ounces at Edna May. Cracow and Mungari both replaced their mining depletion. A maiden Ore Reserve for Marsden has been included contributing 835,000 ounces. Copper Ore Reserves increased by 352,000 tonnes to 564,000 tonnes after accounting for mining depletion and the addition of 371,000 tonnes at Marsden (maiden Ore Reserve)
Further details are provided in Appendix 1 of this release.

Forward looking statements
This report prepared by Evolution Mining Limited (or “the Company”) include forward looking statements. Often, but not always, forward looking statements can generally be identified by the use of forward looking words such as “may”, “will”, “expect”, “intend”, “plan”, “estimate”, “anticipate”, “continue”, and “guidance”, or other similar words and may include, without limitation, statements regarding plans, strategies and objectives of management, anticipated production or construction commencement dates and expected costs or production outputs.
Forward looking statements inherently involve known and unknown risks, uncertainties and other factors that may cause the Company’s actual results, performance and achievements to differ materially from any future results, performance or achievements. Relevant factors may include, but are not limited to, changes in commodity prices, foreign exchange fluctuations and general economic conditions, increased costs and demand for production inputs, the speculative nature of exploration and project development, including the risks of obtaining necessary licenses and permits and diminishing quantities or grades of reserves, political and social risks, changes to the regulatory framework within which the Company operates or may in the future operate, environmental conditions including extreme weather conditions, recruitment and retention of personnel, industrial relations issues and litigation.
Forward looking statements are based on the Company and its management’s good faith assumptions relating to the financial, market, regulatory and other relevant environments that will exist and affect the Company’s business and operations in the future. The Company does not give any assurance that the assumptions on which forward looking statements are based will prove to be correct, or that the Company’s business or operations will not be affected in any material manner by these or other factors not foreseen or foreseeable by the Company or management or beyond the Company’s control.
Although the Company attempts and has attempted to identify factors that would cause actual actions, events or results to differ materially from those disclosed in forward looking statements, there may be other factors that could cause actual results, performance, achievements or events not to be as anticipated, estimated or intended, and many events are beyond the reasonable control of the Company. Accordingly, readers are cautioned not to place undue reliance on forward looking statements. Forward looking statements in these materials speak only at the date of issue. Subject to any continuing obligations under applicable law or any relevant stock exchange listing rules, in providing this information the Company does not undertake any obligation to publicly update or revise any of the forward-looking statements or to advise of any change in events, conditions or circumstances on which any such statement is based.

| 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 conventional diamond core drilling. • Drill holes were positioned strategically to infill gaps in the existing drill data set and test continuity of known lodes/mineralised structures. Collar and down hole surveys were utilised to accurately record final locations. Industry standard sampling, assaying and QA/QC practices were applied to all holes. • Drill core was halved with a diamond saw in 1 m intervals, irrespective of geological contacts. Oxide material that was too soft and friable to be cut with a diamond saw was split with a chisel. Core was cut to preserve the bottom of hole orientation mark and the top half of core sent for analysis to ensure no bias is introduced. RC samples were collected directly from a splitter at the drill rig. • Sample preparation was conducted by SGS West Wyalong and consisted of: • Drying in the oven at 105ºC; crushing in a jaw crusher; fine crushing in a Boyd crusher to 2-3mm; rotary splitting a 3kg assay sub-sample if the sample is too large for the LM5 mill; pulverising in the LM5 mill to nominal; 90% passing 75 µm; and a 50g fire assay charge was taken with an atomic absorption (AA) finish. The detection limit was 0.01 g/t Au. |
| Drilling techniques | •Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face- sampling bit or other type, whether core is oriented and if so, by what method, etc.). |
• Diamond drill holes were drilled HQ diameter through the clay/oxide and NQ diameter through the primary rock to end of hole. • All core has been oriented using accepted industry techniques. |
| Drill sample recovery | •Method of recording and assessing core and chip sample recoveries and results assessed. •Measures taken to maximise sample recovery and ensure representative nature of the samples. •Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
• Provisions are made in the drilling contract to ensure that hole deviation is minimised, and core sample recovery is maximised. Core recovery is recorded in the database. There are no significant core loss or sample recovery issues. Core is reoriented and marked up at 1m 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 very 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. |
• 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. • In 2003 Analytical Solutions Ltd conducted a Review of Sample Preparation, Assay and Quality Control Procedures for Cowal Gold Project. This study, combined with respective operating company policy and standards (North Ltd, Homestake, Barrick and Evolution) formed the framework for the sampling, assaying and QAQC protocols used at Cowal to ensure appropriate and representative sampling. • Results per interval are reviewed for half core samples and if unexpected or anomalous assays are returned an additional quarter core may be submitted for assay. |
| Quality of assay data and laboratory tests |
•The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. •For geophysical tools, spectrometers, handheld XRF instruments etc. the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. •Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of |
• SGS West Wyalong and ALS Orange are utilised as primary sources of analytical information. Round robin checks are completed regulary between the two laboratories. Both labs operate to international standards and procedures and take part in the Geostatistical Round Robin inter-laboratory test survey. The Cowal QA/QC program comprises blanks, Certified Reference Material (CRM), inter- laboratory duplicate checks, and grind checks. • 1 in 30 fine crush residue samples has an assay duplicate. 1 in 20 pulp residue samples has an assay duplicate. • Wet screen grind checks are performed on 1 in 20 pulp residue samples. A blank is submitted 1 in every 38 samples, CRM’s are submitted 1 in 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/QCAdministrator monitors the assayresults |

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 thePrincipal 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. • Cowal uses DataShed software system to maintain the database. Digital assay results are loaded directly into the database. The software performs verification checks including checking for missing sample numbers, matching sample numbers, changes in sampling codes, inconsistent “from-to” entries, and missing fields. Results are not entered into the database until the QA/QC Administrator approves of the results. A QA/QC report is completed for each drill hole and filed with the log, assay sheet, and other appropriate data. Only the Senior Project Geologist and Database Manager have administrator rights to the database. Others can use and sort the database but not save or delete data. |
| Location of data points |
•Accuracy and quality of surveys used to locate drillholes (collar and downhole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. •Specification of the grid system used. •Quality and adequacy of topographic control. |
• All drill hole collars were surveyed using high definition DGPS. All drill holes were surveyed using a downhole survey camera. The first survey reading was taken near the collar to determine accurate set up and then at regular intervals downhole. • On completion of each angled drill hole, a down hole gyroscopic (Gyro) survey was conducted. The Gyro tool was referenced to the accurate surface surveyed position of each hole collar. • The Gyro results were entered into the drill hole database without conversion or smoothing. • An aerial survey was flown during 2003 by AAM Hatch.

| Sample security | •The measures taken to ensure sample security. |
• Drill contractors are issued with drill instructions by an Evolution geologist. The sheet provides drill hole names, details, sample requirements, and depths for each drill hole. Drill hole sample bags are pre-numbered. The drill holes are sampled by Evolution personnel who prepare sample submission sheets. The submission sheet is then emailed to the laboratory with a unique submission number assigned. This then allows individual drill holes to be tracked. • An SGS West Wyalong (SGS) representative collects the samples from site twice daily, however, if samples are being sent to another laboratory a local freight company is used to collect the samples from site and deliver them to the laboratory. Upon arrival, the laboratory sorts each crate and compares the received samples with the supplied submission sheet. The laboratory assigns a unique batch number and dispatches a reconciliation sheet for each submission via email. The reconciliation sheet is checked, and any issues addressed. The new batch name and dispatch information is entered into the tracking sheet. The laboratory processes each batch separately and tracks all samples through the laboratory utilising the LIMS system. Upon completion, the laboratory emails Standard Industry Format (SIF) files with the results for each batch to Evolution personnel. • The assay batch files are checked against the tracking spreadsheet and processed. The drill plan is marked off showing completed drill holes. Any sample or QA/QC issues with the results are tracked and resolvedwiththelaboratory. |
| Audits or reviews | •The results of any audits or reviews of sampling techniques and data. |
• QA/QC Audits of the Primary SGS West Wyalong Laboratory are carried out on an approximately quarterly basis and for the Umpire ASL Orange Laboratory approximately on a six-monthly basis. Any issues are noted and agreed remedial actions assigned and dated for completion. • Numerous internal audits of the database and systems have been undertaken by site geologists and company technical groups from North Ltd, Homestake, Barrick and Evolution. External audits were conducted in 2003 by RMI and QCS Ltd. and in 2011 and 2014 review and validation was conducted by RPA. MiningOne conducted a review of the Cowal Database in 2016 as part of the peer review process for the Stage H Feasibility Study. Recent audits have found no significant issues with data management systems or dataquality. |

• 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.

| 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 reverse circulation (RC) drill chips. • All drill samples were logged prior to sampling. Diamond drill core was sampled to lithological, alteration and mineralisation related contacts, whilst RC samples were collected at 1m downhole intervals. Sampling was carried out according to Evolution protocols and QAQC procedures which comply with industry best practice. All drill-hole collars were surveyed using a total station theodolite or total GPS. • The sampling and assaying methods are appropriate for the orogenic mineralised system and are representative for the mineralisation style. The sampling and assaying suitability was validated using Evolution’s QAQC protocol and no instruments or tools requiring calibration were used as part of the sampling process. • RC drilling was sampled to obtain 1m samples using a static cone splitter from which 3 to 5 kg was crushed and pulverised to produce a 30g to 50g subsample for fire assay. Diamond drillcore sample intervals were based on geology to ensure a representative sample, with lengths ranging from 0.2 to 1.2m. Surface diamond drilling was half core sampled. All diamond core samples were dried, crushed and pulverised (total preparation) to produce a 30g to 50g charge for fire assay of Au. A suite of multi elements are determined using four-acid digest with ICP/MS and/or an ICP/AES finish for some sample intervals. |
| Drilling techniques | •Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face- sampling bit or other type, whether core is oriented and if so, by what method, etc.). |
• RC sampling was completed using a 4.5” to 5.5” diameter face sampling hammer. Diamond holes from surface were predominantly wireline NQ2 (50.5mm) or HQ (63.5mm) holes. • All diamond core from surface core was orientated using the reflex (act II or ezi-ori) tool. |
| Drill sample recovery | •Method of recording and assessing core and chip sample recoveries and results assessed. •Measures taken to maximise sample recovery and ensure representative 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 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. Hole depths were checked against the driller’s core blocks. • Inconsistencies between the logging and the driller’s core depth measurement blocks are investigated. Core recovery has been acceptable. 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 MineReconciliationperformancewhere available. |

• Most diamond core drilled from surface was half core sampled and the remaining half was retained. In the oxide zone, where cutting can wash away samples, some surface holes were full core sampled. • All RC samples were split by a cone or a riffle splitter and collected into a sequenced calico bag. Any wet samples that could not be riffle split were dried then riffle split. • Sample preparation of RC and diamond samples was undertaken by external laboratories according to the sample preparation and assaying protocol established to maximise the representation of the Mungari mineralisation. Laboratories performance was monitored as part of Evolution’s QAQC procedure. Laboratory inspections were undertaken to monitor the laboratories compliance to the Mungari sampling and sample preparation protocol. • The sample and size (2.5kg to 4kg) relative to the particle size (>85% passing 75um) of the material sampled is a commonly utilised practice for effective sample representation for gold deposits within the Eastern Goldfields of Western Australia. • Quality control procedures adopted to maximise sample representation for all sub-sampling stages include the collection of field and laboratory duplicates and the insertion of certified reference material as assay standards (1 in 20) and the insertion of blank samples (1 in 20) or at the geologist’s discretion. Coarse blank material is routinely submitted for assay and is inserted into each mineralised zone where possible. The quality control performance was monitored as part of Evolution’s QAQC procedure. • The sample preparation has been conducted by commercial laboratories. All samples are oven dried (between 85°C and 105°C), jaw crushed to nominal <3mm and if required split by a rotary splitter device to a maximum sample weight of 3.5kg as required. The primary sample is then pulverised in a one stage process, using a LM5 pulveriser, to a particle size of >85% passing 75um. Approximately 200g of the primary sample is extracted by spatula to a numbered paper pulp bag that is used for a 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%. Duplicate samples for both RC chips and diamond core are collected during the sample preparation pulverisation stage. A comparison of the duplicate sample vs. the primary sample assay result was undertaken as part of Evolution’s QAQC protocol. It is considered that all sub-sampling and lab preparations are consistent with other laboratories in Australia and are satisfactory for the intended purpose. • The sample sizes are considered appropriate and in line with industry standards. |

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 2acids (HCIandHN03) before the gold contentis determined by an |

The intent of the procedure for reviewing the performance of certified standard reference material is to examine for any erroneous results (a result outside of the expected statistically derived tolerance limits) and to validate if required; the acceptable levels of accuracy and precision for all stages of the sampling and analytical process. Typically, batches which fail quality control checks are re- analysed. |

• Independent internal or external verification of significant intercepts is not routinely completed. The quality control / quality assurance (QAQC) process ensures the intercepts are representative for the orogenic gold systems. Half core and sample pulps are retained at Mungari if further verification is required. • The twinning of holes is not a common practice undertaken at Mungari. The face sample and drill hole data with the mill reconciliation data is of sufficient density to validate neighbouring samples. Data which is inconsistent with the known geology undergoes further verification to ensure its quality. • All sample and assay information is stored utilising the acQuire database software system. Data undergoes QAQC validation prior to being accepted and loaded into the database. Assay results are merged when received electronically from the laboratory. The geologist reviews the database checking for the correct merging of results and that all data has been received and entered. Any adjustments to this data are recorded permanently in the database. Historical paper records (where available) are retained in the exploration and mining offices. • No adjustments or calibrations have been made to the final assay data reported by thelaboratory. |

• Mineralisation at White Foil is hosted within a brittle quartz gabbro unit. The gold is associated with quartz stockworks. Structural studies confirm 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 typically intersect at an angle to the mineralisation and thereisno observed bias associatedwithdrilling orientation. |

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. |

| 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 30g 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 core is oriented and if so, by what method, etc). |
• A combination of drilling techniques was used across the Cracow Lodes. Diamond NQ3 (standard) and LTK60 were the most commonly used. Reported significant intercepts were all drilled from underground and none of the holes reported were orientated. |
| 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. |

|---|---|---|
| Criteria | Explanation | Commentary |
| • 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 LTK60 and most NQ drill holes reported were whole core sampled. A small number of NQ and all HQ samples were cut and half 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 of the gold mineralisation being sampled. |
| 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 2017 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 classifications applied. •Whether sample compositing has been applied. |
• No significant drill hole exploration results are 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. • 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 significant drill hole results 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. |

•Acknowledgment and appraisal of exploration by other parties. |
• The Cracow Goldfields were discovered in 1932, with the identification of mineralisation at Dawn followed by 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 type, geological setting and style of mineralisation. |
• The Cracow project area gold deposits are in the Lower Permian Camboon Andesite on the south-eastern flank of the Bowen Basin. The regional strike is north-northwest and the dip 20° west- southwest. The Camboon Andesite consists of andesitic and basaltic lava, with agglomerate, tuff and some inter-bedded trachytic volcanics. The andesitic lavas are typically porphyritic, with phenocrysts of plagioclase feldspar (oligocalse or andesine) and less commonly augite. To the west, the Camboon Andesite is overlain with an interpreted disconformity by fossiliferous limestone of the Buffel Formation. It is unconformably underlain to the east by the Torsdale Beds, which consist of rhyolitic and dacitic lavas and pyroclastics with inter-bedded trachytic and andesitic volcanics, sandstone, siltstone, and conglomerate. • Mineralisation is hosted in steeply dipping low sulphidation |

| epithermal veins. These veins found as discrete and as stockwork and are composed of quartz, carbonate and adularia, with varying percentages of each mineral. Vein textures include banding (colloform, crustiform, cockade, moss), breccia channels and massive quartz, and indicate depth within the epithermal system. Sulphide percentage in the veins are generally low (<3%) primarily composed of pyrite, with minor occurrences of hessite, sphalerite and galena. Rare chalcopyrite, arsenopyrite and bornite can also be found. • Alteration of the country rock can be extensive and zone from the central veined structure. This alteration consists of silicification, phyllic alteration (silica, sericite and other clay minerals) and argillic alteration in the inner zone, grading outwards to potassic (adularia) then an outer propylitic zone. Gold is very fined grained and found predominantly as electrum but less common within clots of pyrite. |

| 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 Appendix Drill hole information summary table. |
| Data aggregation methods |
•In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. •The assumptions used for any reporting of metal equivalent values should be clearly stated. |
• Intercept length weighted average techniques, and minimum grade truncations and cut-off grades have been used in this report. Due to the nature of the drilling, some composite grades are less than the current resource cut off of 2.8g/t, but remain significant as they demonstrate mineralisation in veins not previously modelled. • Composite, as well as internal significant values are stated for clarity. • No metal equivalent values are used. |

| Relationship between mineralisation widths and intercept lengths |
•These relationships are particularly important in the reporting of Exploration Results. •If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. •If it is not known and only the downhole lengths are reported, there should be a clear statement to this effect (eg ‘downhole length, true width not known’) |
• The sampling technique confirms the presence of epithermal quartz veining. There is a direct relationship between the mineralisation widths and intercept widths at Cracow. • The assays are reported as down hole intervals and an estimated true width is provided. |
| Diagrams | •Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported. These should include, but not be limited to a plan view of drill hole |
Schematic sections are provided below. Reported resource definition results are not considered exploration results. Plan view of Killarney Plan view of Baz and Crown |
| Balanced reporting | •Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results |
• Assay results reported are of specific regions within the drill hole identified by epithermal quartz veining. |
| Other substantive exploration data |
•Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
• ASD data collected from drill chips and drill core indicated that the dominate clay species recorded graded from Kaolonite close to surface, to Illite smectite, then illite at depth. This was interpreted along with the anomalous arsenic and molybdenite geochemistry, as indicative of the upper levels of an epithermal system, increasing prospectivity at depth. |
