OVERVIEW
Group gold production for the September 2017 quarter was a record 220,971 ounces (Jun qtr: 218,079oz). AISC declined to a record low of A$786/oz (Jun qtr: A$825/oz). Using the average AUD:USD exchange rate for the quarter of 0.7894, Group AISC equated to US$620/oz – ranking Evolution as one of the lowest cost gold producers in the world.
In the September 2017 quarter Evolution delivered record operating mine cash flow of A$210.4 million, up almost 5% despite a 2.8% decrease in the achieved gold price (Jun qtr: A$200.4M). Record net mine cash flow, post all capital, was A$158.3 million (Jun qtr: A$137.1M).
In anticipation of the cash settlement component for the Edna May sale, in addition to the continued strong group cash flow, Evolution elected to make an early debt repayment of A$40.0 million during the quarter. This was directed to the remaining balance in the Senior Secured Term Facility B. As at 30 September 2017, gross debt outstanding under the Senior Secured Syndicated Term Facility D was A$395.0 million. Net debt was reduced to A$342.0 million. The Group cash balance increased to A$50.1 million (30 Jun 2017: A$37.4M).
Standout operational performances for the quarter:
-
Cowal: 70,140oz at an AISC of A$712/oz generating net mine cash flow of A$53.2M
-
Ernest Henry: 23,682oz at a record low AISC of A$(614)/oz producing net mine cash flow of A$52.4M
-
Mt Carlton: 29,994oz at a record low AISC of A$429/oz producing net mine cash flow of A$23.8M
Drilling at Cowal E41 West intersected a new and significant zone of mineralisation outside of the existing Mineral Resource, to the south and at depth. Best intersection: 139m grading 1.17g/t from 269m (E41D2802).
At Mungari, drilling at the Lady Agnes target tested the strike extent of a 200m long mineralised zone and returned a number of high-grade intersections. Successful follow-up drilling at regional resource targets intersected further high-grade mineralisation in the footwall lode at Burgundy, confirming continuity of mineralisation up-dip. Resource definition drilling beneath the White Foil pit extended the quartz gabbro host to the north and returned multiple significant intersections.
Resource definition drilling at Cracow confirmed and extended high-grade mineralisation at Killarney and Imperial which is likely to support resource additions in these areas.
Contracts were awarded during the quarter for the Cowal Float Tails (Dual) Leach Project which is expected to increase recoveries by 4 – 6%. The Cowal Stage H project is progressing on schedule and on budget.
The sale of the Edna May gold mine to Ramelius Resources Limited (ASX: RMS) was successfully completed on 3 October 2017. Evolution has received the A$40.0 million in upfront cash payment from Ramelius. The sale agreement also includes up to A$50 million of contingent payments. The structure is described in the ASX announcement released on 18 September 2017 titled Agreement to Divest Edna May Gold Mine.
Evolution invested A$2.5 million for a 15.1% cornerstone shareholding in Riversgold Limited (ASX: RGL) which listed on the ASX on 10 October 2017. Riversgold is a gold-focused exploration company led by Doray Minerals founder Allan Kelly and former Sirius Resources Executive Director Jeff Foster. Initial projects in the portfolio include properties located in Western Australia, South Australia, Alaska and Cambodia.
During the quarter the Board approved a change to Evolution’s dividend policy to, whenever possible, paying a half-yearly dividend equivalent to 50% of the Group’s after-tax earnings. On 29 September 2017 Evolution paid a fully franked dividend of 3 cents per share totalling A$50.7 million.
Ms Andrea Hall was appointed as a Non-Executive Director of the Company and a member of the Audit Committee effective 1 October 2017. With a strong background in financial services and extensive experience on a diverse range of boards Ms Hall will make a valuable contribution to Evolution’s Board.

OVERVIEW
FY18 Guidance
Following the sale of Edna May, Evolution revised its FY18 gold production guidance to 750,000 – 805,000 ounces at an AISC of A$820 – A$870 per ounce. Costs in the September quarter were below the full year guidance due to better than expected grades at Cowal and Mt Carlton, a higher than forecast copper price which significantly lowered Ernest Henry’s costs, and lower capital expenditure at Cowal which, as originally planned, will increase in the remaining quarters as project activities fully ramp up.
As a result of the sale of Edna May, December 2017 quarter production is expected to be 180,000 – 190,000 ounces of gold. However, total operating mine cashflow is expected to remain similar to the September quarter provided commodity prices remain at current levels.

OPERATIONS
Cowal, New South Wales (100%)
Cowal had an outstanding quarter producing 70,140oz of gold at an AISC of A$712/oz (Jun qtr: 62,382oz, AISC A$762/oz).
Mine operating cash flow for the quarter was A$67.4 million. Net mine cash flow of A$53.2 million was achieved (Jun qtr: A$29.9 million), post sustaining capital of A$6.8 million and major capital of A$7.4 million associated with the Stage H and Float Tails projects. Total capital expenditure is planned to ramp up in the coming quarters and remains on plan to FY18 guidance of A$52.5 – A$57.5M in sustaining capital and A$85.0 – A$100.0M in major project capital.
Ore mining activities focussed on the E42 Stage G cutback to the current operating level of 876mRL.
The Stage H project is progressing on schedule and on budget. Focus for the quarter was on procurement of equipment and relocation of infrastructure. Mining excavation was concentrated on relocation of stockpiles and waste dumps located within the perimeter of Stage H. Most of this work was completed in the quarter. In the December 2017 quarter focus will shift to excavation of the Stage H pit cutback itself.
Contracts were awarded for the project management and construction of the Float Tails Leach project. Engineering design work has commenced and major construction works are expected to start in the March 2018 quarter. The project is progressing on schedule and is expected to increase recoveries by 4 – 6%.
Mungari, Western Australia (100%)
Mungari produced 30,353oz of gold at an AISC of A$1,059/oz (June 2017 qtr: 29,965oz, AISC A$1,313/oz).
Mine operating cash flow for the quarter was A$21.9 million. Net mine cash flow of A$8.9 million was achieved (Jun qtr: A$5.1 million), post sustaining capital of A$2.2 million and major capital of A$10.8 million, which was predominantly related to the waste cutback of the White Foil open pit.
The Frog’s Leg underground mine produced 135kt ore tonnes at a grade of 4.5g/t gold. As planned, total development was reduced after scaling back to one jumbo for development and rehab operations in FY18. Ore production was in line with plan and reconciled well against the geological model.
White Foil completed mining Stage 2b, then transitioned into the Stage 3 cutback. Material movement increased to 2.7Mt.
The process plant performed very well for the quarter. A continued focus on costs had a positive impact on the operation which saw the low unit costs of the June 2017 half-year maintained. The additional Knelson concentrator was successfully commissioned allowing for increased gold recovery by the gravity circuit. The particle size analyser also transitioned to automatic sampling which will allow for improved trending and optimisation throughout the plant. A full mill reline is scheduled in the December 2017 quarter.
During the quarter, Cowal hosted the Evolution Mines Rescue challenge and the NSW Mines Rescue challenge. These were successfully staged in the local community of West Wyalong and were an opportunity to showcase the skill set of each of our site teams.

OPERATIONS
Mt Carlton, Queensland (100%)
Mt Carlton had another exceptional quarter producing 29,994oz of payable gold contained in 16,100 dry metric tonnes (dmt) of gold concentrate and 4,015oz in gold doré (Jun qtr: 28,270oz in 15,128 dmt and 3,000oz gold doré). Record low costs were achieved with an AISC of A$429/oz (Jun qtr: A$616/oz).
Mine operating cash flow for the quarter was A$30.9 million and net mine cash flow was A$23.8 million (Jun qtr: A$29.9 million), post sustaining and major capital of A$7.1 million.
A total of 205,229 tonnes of V2 ore grading 5.87 g/t gold was treated. Processing plant recoveries continue to improve achieving 91.2% (FY17: 90.1%). Ongoing optimisation work is expected to further increase recoveries. Western zone highgrade ore through the plant continues to see strong positive reconciliation.
Mining of the Stage 3a western end of the V2 open pit focussed on accessing high-grade ore to blend with low to medium grade Run of Mine (ROM) stocks. Mining of the eastern end Stage 3b pre-strip continued on schedule.
The gravity circuit produced 4,015oz of gold doré (Jun qtr: 3,000oz). This circuit will continue to improve in the December 2017 quarter as ongoing optimisation is expected to result in increased operational availability. In addition, studies are continuing to identify options to reduce the impact of clay/oxidised ore in the flotation circuit that could lead to increased plant throughput.
Mt Rawdon, Queensland (100%)
Mt Rawdon produced 21,766oz of gold in the September quarter at an AISC of A$1,083/oz (Jun qtr: 25,808oz, AISC A$922/oz).
Mine operating cash flow for the quarter was A$12.7 million. Mt Rawdon delivered net mine cash flow of A$7.5 million (Jun qtr: A$9.3 million), post sustaining capital and major capital of A$5.2 million.
Mining activities were focussed on the progression of Stage 4. Ore was sourced from the western and northern section of the open pit with waste movement activities concentrated in the southern and western sections of the pit.
Total ore mined was 1,037kt at an average grade of 0.86g/t gold. The plant processed 795kt at an average head grade of 0.98g/t gold.
Drilling activities testing targets immediately to the west and north of the pit are currently being undertaken with the aim of converting inferred resources that contain higher grade mineralisation.
In the December 2017 quarter mining activities will continue to focus on waste movement from the southern and western sections of Stage 4 exposing ore from these benches in subsequent quarters.
The Underground/Stage 4 pit Definitive Feasibility Study continued during the quarter. The current resource definition drilling program is expected to be completed in the December 2017 quarter.

Blue Funnel South
A 17,000m AC drilling program was completed testing favourable structure and stratigraphy along an estimated 6km strike length. AC drilling results defined three anomalous gold zones. These anomalies will be followed up with bedrock drilling in the December 2017 quarter.
A diamond hole was drilled below a significant intercept returned from previous AC drilling. This hole (EVDD0007) intersected an altered and brecciated conglomerate returning a downhole interval of 16.8m grading 0.89g/t Au (from 244m)[1] . This is the first bedrock hole drilled by Evolution in this stratigraphic succession. Pathfinder geochemistry has added strong support that a new target style has been developed along the 6km long trend to date. Further work is underway to follow-up anomalous results targeting a new bedrock source for mineralisation in this area.

Frog’s Leg South, Innis and Smithfield
Deep diamond drilling south of Frog’s Leg deposit has demonstrated that structures hosting the ore at Frog’s Leg persist, however the favourable host stratigraphy is pinching out. A seven-hole drill program was completed at Innis and Innis South to test if the prospective host rocks redevelop along strike and at depth. Further work to follow the structure to the south will be undertaken.
Drilling at Smithfield, southeast of White Foil, has returned broad zones of intense alteration associated with what is interpreted to be the southern continuattion of the Strezleki Shear /zone which hosts the Raliegh vein further north. The target at Smithfield is a narrow high-grade vein deposit. Addional drilling is planned for the coming quarter.

Drilling into the lower Mist lode commenced testing the depth extension of mineralisation up to 150m below the Ore Reserve limits. Logging, assaying and the geological interpretation is in progress.
White Foil
Early in the quarter, results for three drill holes designed to test an area at the northern end of the White Foil resource were received. The holes intersected significant widths and grades of mineralisation including[1] :
-
80.2m (64.2m etw) grading 1.98g/t Au from 268.5m (WFRD027)
-
47.5m (38m etw) grading 3.36g/t Au from 269.5m (WFRD028)
-
7.5m (6m etw) grading 4.11g/t Au from 237m (WFRD029W1)
Drilling confirmed the presence and continuity of mineralisation down plunge, with the quartz gabbro host being considerably thicker than previously modelled and remaining open to the north. As a result, a further four drill holes were completed to confirm the northern extension of the quartz gabbro. A total of 1,395m were drilled comprising of 120m of RC pre-collars and 1,275m of diamond drilling.
Quartz gabbro with quartz veining and visible gold was intersected in all holes up to 120m north of previous drilling in the area. Best intersections received to date included:
-
25m (15m etw) grading 3.27g/t Au from 303.7m (WFRD033)

Regional exploration
Results received from the June quarter drilling at the Walhalla prospect, located 2.5km northeast of the Cracow Operation, provided further evidence the prospect represents the upper levels of a preserved mineralised epithermal system. Interpretation of the stratigraphy, vein textures, geochemistry and alteration of the structures indicates potential for gold mineralisation at depth to the southern end of the target. A drill hole to test this concept is planned to commence in the December 2017 quarter.

Results from a framework drilling program at Edna Beryl were received during the quarter with no significant assays reported. No additional work is planned at the Edna Beryl deposit in the coming quarter.
A review of the high-grade copper mineralisation along the Gecko / Goanna corridor was completed. Several high-grade, shear-hosted copper intersections define a potential strike extent of over 2km. An eight-hole RC drilling program aimed at testing the potential scale and continuity of the system will commence in early November.
South Gawler, South Australia (earning up to 80%)
A 2700 station (400m x 400m) gravity survey was completed over approx. 400km[2] in the central region of the Menninnie Metals’ South Gawler tenements. The survey was designed to delineate isolated gravity highs associated with discrete Ironstone Hosted Copper Gold (IOCG) deposits. Surface exposures of hydrothermal quartz and ironstone fragments are potentially distal expressions of an IOCG system at shallow to moderate depth. Results from the gravity survey will be integrated with surface geochemistry to define drill targets for testing in early December.

Cowal Section 1 Sampling Techniques and Data
| Criteria | Explanation | Commentary |
|---|---|---|
| Sampling techniques | •Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as downhole gamma sondes, handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling. •Include reference to measures taken to ensure sample representation and the appropriate calibration of any measurement tools or systems used. •Aspects of the determination of mineralisation that are material to the Public Report. •In cases where ‘industry standard’ work has been completed this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems, or unusual commodities/mineralisation types (e.g. submarine nodules). |
Holes in this report consist of 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. |

Provisions are made in the drilling contract to ensure that hole deviation is minimised and core sample recovery is maximised. This is monitored by a geologist on a hole by hole basis. Core recovery is recorded in the database. There are no significant core loss or sample recovery issues. Core is reoriented and marked up at 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 no apparent relationship between core-loss and grade. |

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. |

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. |

CRM’s that are outside the ±2SD acceptance criteria are re-assayed until acceptable results are returned. Material used for blanks is uncertified, sourced locally, comprising fine river gravel which has been determined to be below detection limit. A single blank is submitted every 38 samples. Results are reviewed by the QA/QC Administrator upon receipt for non-compliances. Any assay value greater than 0.1 g/t Au will result in a notice to the laboratory. Blank assays above 0.20 g/t Au result in re-assay of the entire batch. The duplicate assays (Au2) are taken by the laboratory during the subsampling at the crushing and pulverisation stages. The results were analysed using scatter plots and relative percentage difference (RPD) plots. Repeat assays represent approx. 10% of total samples assayed. Typically, there is a large variance at the lower grades which is common for low grade gold deposits, however, the variance decreases to less than 10% for grades above 0.40 g/t Au, which is the cut-off grade used at Cowal. Approximately 5% of the pulps, representing a range of expected grades, are submitted to an umpire assay laboratory (ALS Orange) to check for repeatability and precision. Analysis of the data shows that the Principal Laboratory is performing to an acceptable level. |

| Verification of sampling and assaying |
• The verification of significant intersections by either independent or alternative company personnel. •The use of twinned holes. •Documentation of primary data, data entry procedures, data verification and data storage (physical and electronic) protocols. •Discuss any adjustment to assay data |
No dedicated twinning drilling has been conducted for this drill program however some holes pass through areas of higher confidence material in order to reach target zones. These areas may be used to validate exiting drill information. Cowal uses DataShed software system to maintain the database. Digital assay results are loaded directly into the database. The software performs verification checks including checking for missing sample numbers, matching sample numbers, changes in sampling codes, inconsistent “from-to” entries, and missing fields. Results are not entered into the database until the QA/QC Administrator approves of the results. A QA/QC report is completed for each drill hole and filed with the log, assay sheet, and other appropriate data. Only the Senior Project Geologist and Database Manager have administrator rights to the database. Others 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. This digital data has been combined with surveyed drill hole collar positions and other features (tracks, lake shoreline) to create a digital terrain model (DTM). The survey was last updated in late 2014. In 2004, Cowal implemented a new mine grid system with the assistance of AAM Hatch. The current mine grid system covers all areas within the ML and ELs at Cowal with six digits. |

•Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. •If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
Diamond holes were positioned to optimise intersection angles of the target area. In respect of the drilling at E41W drilling is targeted to drill at right angles to the dominant vein direction however the extent of the vein package is currently unknown. The Drilling at Galway Regal is oriented perpendicular to the known mineralised package. |
| Sample security | •The measures taken to ensure sample security. |
Drill contractors are issued with drill instructions by an Evolution geologist. The sheet provides drill hole names, details, sample requirements, and depths for each drill hole. Drill hole sample bags are pre-numbered. The drill holes are sampled by Evolution personnel who prepare sample submission sheets. The submission sheet is then emailed to the laboratory with a unique submission number assigned. This then allows individual drill holes to be tracked. An SGS West Wyalong (SGS) representative collects the samples from site twice daily, however, if samples are being sent to another laboratory a local freight company is used to collect the samples from site and deliver them to the laboratory. Upon arrival, the laboratory sorts each crate and compares the received samples with the supplied submission sheet. The laboratory assigns a unique batch number and dispatches a reconciliation sheet for each submission via email. The reconciliation sheet is checked and any issues addressed. The new batch name and dispatch information is entered into the tracking sheet. The laboratory processes each batch separately and tracks all samples through the laboratory utilising the LIMS system. Upon completion, the laboratory emails Standard Industry Format (SIF) files with the results for each batch to Evolution personnel. The assay batch files are checked against the tracking spreadsheet and processed. The drill plan is marked off showing completed drill holes. Any sample or QA/QC issues with the results are tracked and resolved with the laboratory. |
| 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 data quality. |

Mungari Section 1 Sampling Techniques and Data
| Criteria | Explanation | Commentary |
|---|---|---|
| Sampling techniques | •Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as downhole gamma sondes, handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. •Include reference to measures taken to ensure sample representation and the appropriate calibration of any measurement tools or systems used. •Aspects of the determination of mineralisation that are material to the Public Report. •In cases where ‘industry standard’ work has been completed this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems, or unusual commodities/mineralisation types (e.g. submarine nodules). |
• Sampling of gold mineralisation at Mungari was undertaken using diamond core (surface and underground) and reverse circulation (RC) drill chips. • All drill samples were logged prior to sampling. Diamond drill core was sampled to lithological, alteration and mineralisation related contacts, whilst RC samples were collected at 1m downhole intervals. Sampling was carried out according to Evolution protocols and QAQC procedures which comply with industry best practice. 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 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 1.0m. 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 both surface and underground were predominantly wireline NQ2 (50.5mm) or HQ (63.5mm) holes. • All diamond core from surface and some underground 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. Holes depths were checked against the driller’s core blocks. • Inconsistencies between the logging and the driller’s core depth measurement blocks were investigated. Core recovery has been excellent as all holes are drilled into fresh competent rock. Surface drilling recoveries were generally excellent with the exception of oxide zones however these rarely fell below 90%. • Measures taken to maximise sample recovery include instructions to drillers to slow down drilling rates or reduce the coring run length in less competent ground. • Analysis of drill sample bias and loss/gain was undertaken with the Overall MineReconciliationperformancewhere available. |

• Most diamond core drilled from surface was half cored sampled and the remaining half was retained. In the oxide zone, where cutting can wash away samples, some surface holes were full core sampled. A proportion of underground diamond core holes were half core sampled and the remaining core retained for further geological or metallurgical analysis. • All RC samples were split by a cone or a riffle splitter and collected into a sequenced calico bag. Any wet samples that could not be riffle split were dried then riffle split. • Sample preparation of RC and diamond samples was undertaken by external laboratories according to the sample preparation and assaying protocol established to maximise the representation of the Mungari mineralisation. Laboratories performance was monitored as part of Evolution’s QAQC procedure. 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 is designed to measure the total gold within a sample. Fire assay has been confirmed as a suitable technique for orogenic type mineralisation. It has been extensively used throughout the Goldfields region. Screen fire assay and LeachWELL / bottle roll analysis techniques have also been used to validate the fire assay techniques. • The technique utilised a 30g, 40g or 50g sample charge with a lead flux, which is decomposed in a furnace with the prill being totally digested by 2 acids (HCI and HN03) before the gold content is determined by an AAS machine. • No geophysical tools or other remote sensing instruments were utilised for reporting or interpretation of gold mineralisation. • Quality control samples were routinely inserted into the sampling sequence and were also inserted either inside or around the expected zones of mineralisation. The intent of the procedure for reviewing the performance of certified standard reference material is to examine for any erroneous results (a result outside of the expected statistically derived tolerance limits) and to validate if required; the acceptable levels of accuracy and precision for all stages of the sampling and analytical process. Typically batches which fail quality control checks arere-analysed. |

| Verification of sampling and assaying |
• The verification of significant intersections by either independent or alternative company personnel. •The use of twinned holes. •Documentation of primary data, data entry procedures, data verification and data storage (physical and electronic) protocols. •Discuss any adjustment to assay data |
• Independent internal or external verification of significant intercepts is not routinely completed. The quality control / quality assurance (QAQC) process ensures the intercepts are representative for the orogenic gold systems. Half core and sample pulps are retained at Mungari if further verification is required. • The twinning of holes is not a common practice undertaken at Mungari. The face sample and drill hole data with the mill reconciliation data is of sufficient density to validate neighbouring samples. Data which is inconsistent with the known geology undergoes further verification to ensure its quality. • All sample and assay information is stored utilising the acQuire database software system. Data undergoes QAQC validation prior to being accepted and loaded into the database. Assay results are merged when received electronically from the laboratory. The geologist reviews the database checking for the correct merging of results and that all data has been received and entered. Any adjustments to this data are recorded permanently in the database. Historical paper records (where available) are retained in the exploration and mining offices. • No adjustments or calibrations have been made to the final assay datareported by thelaboratory. |
| Location of data points |
•Accuracy and quality of surveys used to locate drillholes (collar and downhole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. •Specification of the grid system used. •Quality and adequacy of topographic control. |
• All surface drill holes at Mungari have been surveyed for easting, northing and reduced level. Recent data is collected and stored in MGA 94 Zone 51 and AHD. • Resource drill hole collar positions are surveyed by the site- based survey department or contract surveyors (utilising a differential GPS or conventional surveying techniques, with reference to a known base station) with a precision of less than 0.2m variability. • Underground down hole surveys consist of regular spaced digital single-shot borehole camera shots (generally 30m apart down hole), and digital electronic multi-shot surveys (generally 3m apart down hole). In instances where strong ground magnetics affect the accuracy of the measured azimuth reading, then these results are removed. The RC and surface drill hole survey data consists of surveys taken utilising north seeking gyro instruments. Gyro survey measurements are obtained every 5 to 10m down hole. A proportion of these holes are downhole surveyed using a digital single shot survey technique similar to that of the underground holes, except the down-hole survey measurement is at a spacing typically 25- 50m apart. • Topographic control was generated from aerial surveys and detailed Lidar surveys to 0.2m accuracy. Underground void measurements are computed using CavityMonitoring System |

| Data spacing and distribution |
•Data spacing for reporting of Exploration Results. •Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. •Whether sample compositing has been applied. |
• The nominal drill spacing for Exploration drilling is 80m x 80m or wider and for Resource Definition is 40m x 40m or in some areas 20m x 20m. This spacing includes data that has been verified from previous exploration activities on the project. • Data spacing and distribution is considered sufficient for establishing geological continuity and grade variability appropriate for classifying a Mineral Resource. • Sample compositing was not applied due to the often-narrow mineralised zones. |
| Orientation of data in relation to geological structure |
•Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. •If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
• Mineralisation at Frog’s Leg is hosted within a number of steeply dipping NNW-SSE structures that are vertical or dipping steeply (~80 degrees) to the west. Surface and underground drilling intersect the mineralisation at an angle to minimise bias. • Mineralisation at White Foil is hosted within a brittle quartz gabbro unit. The gold is associated with quartz stockworks. Structural studies confirms the presence of two main vein sets at White Foil with a dominant moderately NNW dipping set (51º/346º dip and dip direction) and a secondary SSE dipping set (56º/174º dip and dip direction).. An identifiable systematic bias associated with drilling direction has not been established. The main strike to the gabbro unit is NNW-SSE and it plunges steeply towards the NNE. The predominant drill direction was to the SE. • Surface holes and underground resource holes typically intersect at an angle to the mineralisation and there is no observed bias associated with drilling orientation. • The relationship between the drilling orientation and the orientation of key mineralised structures at Mungari is not considered to have introduced a sampling bias and is not considered to be material. In a minority of instances on extreme edges at the Frog’s Leg deposit the drill angle is sub parallel with the lodes and does not intersect the width of the mineralisation. • Resource Definition drilling is typically planned to intersect ore domains in an orientation that does not introduce sample bias. A small number of holes are drilled at sub-optimal orientations to testforalternate geological interpretations. |
| Sample security | •The measures taken to ensure sample security. |
• Chain of custody protocols to ensure the security of samples were followed. Prior to submission samples were retained on site and access to the samples were restricted. Collected samples are dropped off at the respective commercial laboratories in Kalgoorlie. The laboratories are contained within a secured/fenced compound. Access into the laboratory is restricted and movements of personnel and the samples are tracked under supervision of the laboratory staff. During some drill campaigns some samples are collected directly from site by the commercial laboratory. While various laboratories have been used, the chain of custody and sample security protocols haveremained similar. |
| Audits or reviews | •The results of any audits or reviews of sampling techniques and data. |
• The Mungari geology and drilling database was reviewed by acQuire in December 2015 and no material issues were identified. |

||
Geology •Deposit type, geological setting and style of mineralisation. • The Frog’s Leg deposit is located in the southern portion of the Kundana mining area, within the Achaean Norseman-Wiluna greenstone belt of the Eastern Goldfields Province. The Kundana gold deposits are structurally related to the Zuleika Shear Zone, a regional NNW-trending shear zone that juxtaposes the Ora Banda domain to the east and the Coolgardie domain to the west. The Frog’s Leg deposit is located on the sheared contact between the porphyritic “cat rock” (regionally known as the Victorious Basalt) and volcaniclastic rocks of Black Flag Beds • The White Foil gold deposit is a quartz stockwork hosted in a gabbro. The gabbro is differentiated broadly into a quartz-rich phase in the west. This quartz gabbro unit is the most hydrothermally altered unit and contains the bulk of the gold mineralisation. The White Foil deposit is bounded to the west by hangingwall volcaniclastic rocks. To the east mineralisation becomes irregular and uneconomic in the more melanocratic phase of gabbro. Mineralisation is controlled by sheeted systems of stockwork veining, which has imparted strong alteration and sulphidation to the quartz gabbro. • The Burgundy prospect is located in the central portion of the Mungari tenements within the Kunanalling camp. It occurs within the Telegraph syncline located in the hangingwall to the Kunanulling Shear Zone. Mineralisation occurs as a stockwork vein array within a sheared dolerite with layers of interbedded shale. A narrow and more diffuse zone of mineralisation occurs within volcanoclastic sediments approximately 50m into the hangingwall from the main zone. Mineralisation is truncated by at least 2 late D4 faults over distances of 10’s of metres. • The Emu deposit is located in the central portion of the Mungari tenements within the Kunanalling Camp. The deposit is hosted in the footwall to the Kunanalling Shear zone. Mineralisation occurs as a sheeted vein array within a structurally thickened area of quartz dolerite. • The Johnsons Rest prospect in located in the central portion of the Mungari tenements, in the Broads Dam camp. Mineralisation |

| is hosted by the Johnsons Rest shear, which strikes NW and dips steeply east. The shear is slightly oblique to geology. In the main area, the mineralisation is hosted withed basalt, however further north the shear runs onto and along a contact between ultramafic (HW) and basalt (FW). Mineralisation is focused into areas of pre- conditioned carbonate alteration, which has become embrittled, and failed during subsequent deformation related to gold mineralisation. • The Red Dam prospect is located in the northern portion of the Mungari tenements, in the Broads Dam camp. An ultramafic unit is located within a sequence of volcanoclastic units along a NW trend, that have been cut by late N trending D4 faults. Mineralisation occurs as a quartz vein stockwork around the D4 faults, preferentially developed around contacts between the different lithological units. A supergene blanket of mineralisation occurs above primary mineralisation, at a depth approximately 25m below surface • The Carbine North prospect is located in the northern portion of the Mungari tenements, in the Carbine camp. The deposit is located on the Carbine Shear which may be a linking shear between the Kunanalling and Zuleika shear zones. The geology trends NW and from FW to HW consists of an ultramafic to High Mg basalt which is overlain by a sequence of volcanoclastic sediments. Primary mineralisation occurs in two parallel shear zones, one within the ultramafic, the second on the contact between the two geological units. Supergene mineralisation has developed as a blanket, overlying the primary mineralisation approximately 30m below surface • The Broads Dam prospect in located in the central portion of the Mungari tenements, in the Broads Dam camp. The geology is complex, but consists of a series of NW trending units comprising basalt, ultramafic, dolerite and volcanoclastic sediments. Shale units occur on some contact. To the furthest west, the sequence is truncated by the Kurrawang Basin sequence of sandstones and conglomerate. Mineralisation is localised along the Broads Dam – Blue Funnel Shear. Mineralisation is best developed in zones where carbonate alteration within basalt and ultramafic has made the rocks brittle, with mineralisation occurring in quartz veins emplace as a result of brittle deformation during the gold mineralising event. Variable supergene mineralisation may locally occur above primary mineralisation • The Blue Funnel prospect in located in the central portion of the Mungari tenements, in the Broads Dam camp. The geology is complex, but consists of a series of NW trending units comprising basalt, ultramafic, dolerite and volcanoclastic sediments. Shale units occur on some contact. To the furthest west, the sequence is truncated by the Kurrawang Basin sequence of sandstones and conglomerate. Mineralisation is localised along the Broads Dam – Blue Funnel Shear. Mineralisation is best developed in ultramafic where carbonate alteration has made the rocks brittle, with mineralisation occurring in quartz veins emplaced as a result of brittle deformation during the gold mineralising event. Variable supergene mineralisation may locally occur above primary mineralisation • The Blue Funnel South prospect is located in the central portion of Mungari tenements, in the Broads Dam camp. The geology comprises a folded package of Kurrawang Group late basin conglomerates, sandstones and siltstones in the footwall of the Zuleika Shear zone. Mineralisation appears to be associated with late brittle structures or splays associated with the Zuleika Shear zone and comprises pervasive albite alteration with minor sulphides in an angular breccia. The mineralisation appears to be confined to a conglomerate facies. • The Lady Agnes prospect is located in the northern portion of the Mungari tenements, in the Ora Banda camp. The geology comprises Bent Tree Basalt. The mineralisation is associated with structures related to the Grants Patch Fault and is hosted by a deeply oxidised structure containing pervasive goethite and minor quarts. |

Cracow Section 1 Sampling Techniques and Data
| Criteria | Explanation | Commentary |
|---|---|---|
| Sampling techniques | •Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as downhole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. •Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. •Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) |
• Sample types collected at Cracow and used in the reporting of assays were all diamond drill core. • Sample intervals for drill core were determined by visual logging of lithology type, veining style/intensity and alteration style/intensity to ensure a representative sample was taken. In addition, sampling is completed across the full width of mineralisation. Minimum and maximum sample intervals were applied using this framework. No instruments or tools requiring calibration were used as part of the sampling process. • Industry standard procedures were followed with no significant coarse gold issues that affected sampling protocols. Nominal 3 kg samples from drill core are subsampled to produce a 50g sample submitted for fire assay. |
| Drilling techniques | •Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether 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. • Mineralisation at Cracow was within Quartz-Carbonate fissure veins, and therefore sample loss rarely occurs in lode material. No relationship between sample recovery and grade was observed. |

| Logging | •Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. •Whether logging is qualitative or quantitative in nature. Core (or costean, channel etc) photography. • The total length and percentage of the relevant intersections logged. |
• Geological logging was undertaken onsite by Evolution employees and less frequently by external contractors. Logging was completed using LogChief_Software and uploaded directly to the database. A standard for logging at Cracow was set by the Core Logging Procedure_Cracow Procedures Manual 3rd Edition. Drill Core is logged recording lithology, alteration, veining, mineral sulphides and geotechnical data. RC chip logging captured the same data with the exclusion of geotechnical information. • Logging was qualitative. All drill core was photographed wet using a camera stand and an information board to ensure a consistent standard of photography and relevant information was captured. • All core samples collected were fully logged. |
| Sub-sampling techniques and sample preparation |
•If core, whether cut or sawn and whether quarter, half or all core taken. •If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. •For all sample types, the nature, quality and appropriateness of the sample preparation technique. •Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. •Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. • Whether sample sizes are appropriate to the grain size of the material being sampled. |
• All drill holes reported were whole core sampled. • Whole core samples were crushed in a jaw crusher to > 70% passing 2mm; half of this material was split with a riffle splitter for pulverising. No RC samples required crushing in the jaw crusher. Core and RC samples were pulverised for 10-14 minutes in a LM5 bowl with a target of 85% passing 75µm. Grind checks were undertaken nominally every 20 samples. From this material approximately 120g was scooped for further analysis and the remaining material re-bagged. Duplicates were performed on batches processed by ALS every 20 samples at both the crushing and pulverising stages. This sample preparation for drill samples is considered appropriate for the style of mineralisation at Cracow. • Duplicates were performed on batches processed by ALS Brisbane every 20 samples at both the crushing and pulverising stages. • Grind checks were undertaken nominally every 20 samples, to ensure sample grind target of 85% passing 75µm was met. Duplicates were completed every 20 samples at both the crushing and pulverising stages, with no bias found at any sub-sampling stage. • The sample size collected is considered to be appropriate for the size and characteristic 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 2016 by Cracow personnel. |
| Verification of sampling and assaying |
•The verification of significant intersections by either independent or alternative company personnel. •The use of twinned holes. |
• 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. |

•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. |

•Acknowledgment and appraisal of exploration by other parties. |
• 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 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. |

| 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. |

Mt Carlton
Mt Carlton Section 1 Sampling Techniques and Data
| Criteria | Explanation | Commentary |
|---|---|---|
| Sampling techniques | •Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as downhole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. •Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 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) |
• Reported assay data for this report is based on PQ, HQ diameter core. PQ was drilled largely through weathered zones and broken ground of weak mineralisation then followed with HQ diamond core to end of hole. Oxidised core (PQ) is usually sampled using kitchen knife whiles competent core HQ 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 SGS Townsville facility. Weights of samples dried at 105OC are recorded and crushed to 2mm. Samples are split and excess bagged if crushed weight is greater than 3kg. LM5’s are used to pulverise samples to 85% passing 75um. A 200g pulp split is taken for analysis which comprise; a 50g charge fire assay with AA finish and ICP-AES for multi-element suite. |
| Drilling techniques | •Drill type (eg core, reverse circulation, open- hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face- sampling bit or other type, whether core is oriented and if so, by what method, etc). |
• Diamond drilling was undertaken with PQ and HQ bits. Holes were usually started with PQ and completed with HQ or NQ on occasions due to poor ground conditions. Coring was by triple tube and all cores were oriented using Reflex Act RD2 orientation tool. |
| Drill sample recovery | •Method of recording and assessing core and chip sample recoveries and results assessed. •Measures taken to maximise sample recovery and ensure representative nature of the samples. •Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
• Field recovery records for core are reconciled with driller’s depth blocks. Percentage core recovery is calculated and stored in a database along with Geotechnical records. • Drillers are informed of the importance of core recovery, all necessary care is taken to ensure every drill run has maximum core recovered. Shot core runs were done in bad ground to ensure core loss is significantly minimised. Areas of poor core recovery were noted during logging. “CL” is marked on depth blocks denoting core loss. Intervals of core losses are considered during sampling and referenced when assessing assay data. • No discernible relationship between core loss and grade has been identified. Mineralisation is hosted within fresh advance argillic rhyodacite unit where core recoveries are more than 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 more than 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 more than 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 and analytical spectral data (ASD) data are captured as part of the logging process. Lithogeochemical samples are collected in areas where lithology units are not easily discernible. The logging process is appropriate for Mineral Resource estimates, mining and metallurgical studies. • General logging data captured are; qualitative (descriptions of the various geological features and units) and quantitative (numbers representing alteration intensities, vein densities, rock mass quality and defect planes) • Drill holes (All core) were logged as full core prior to photographing (dry and wet) and cutting. |
| Sub-sampling techniques and sample preparation |
•If core, whether cut or sawn and whether quarter, half or all core taken. •If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. •For all sample types, the nature, quality and appropriateness of the sample preparation technique. •Quality control procedures adopted for all sub- sampling stages to maximise representivity of samples. •Measures taken to ensure that the sampling is representative of the in-situ material collected, including for instance results for field duplicate/second-half sampling. •Whether sample sizes are appropriate to the grain size of the material being sampled. |
• Core was cut using diamond core saw along orientation lines and sampled at nominal one metre intervals from the same side in the tray at all times. All core samples submitted to SGS Townsville for analysis are half core except for duplicate core which is quarter core. The remaining half/quarter core is persevered in the tray for further test work or re-logging if required. • Core sample preparation involves oven drying, coarse crushing to ~2mm followed by pulverisation of the entire sample (total prep) using LM5 grinding mills to a grind size 85% passing 75 microns. A 50g sub-sample is utilised for fire assay. Sample preparation and analysis follows industry best practise and appropriate for the mineralisation. • Certified reference material along with blanks and field duplicates are inserted into sample stream along with the original samples. Standards, blanks and field duplicates cover 5% of sample volume to monitor sample preparation and the analytical process. • The high sulphidation epithermal mineralisation at Mt Carlton occurs in zones of highly silicic altered hydrothermal breccias overprinted by several phases of sulfur salts containing bonanza gold grades and anomalous base-metal grades. Core sample size of 2-31/2kg sample length over 1m is suitable for the mineralisation type. • The sample sizes are considered appropriate for the material sampled. It is believed that grain size bears no impact on sampled material. |
| Quality of assay data and laboratory tests |
•The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. •Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. |
• All core samples are analysed at SGS 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 SGS 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 (Potable Terra Spec Halo). 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 SGS is accessible online. The analytical system at SGS captures data at all stages of the sample preparation and analytical process. The system minimises human error and ensures high data integrity. SGS participatesinan international “RoundRobin”QAQC program |
