OVERVIEW

Group Total Recordable Injury Frequency (TRIF) at 31 December 2018 was 7.3 (30 Sep 2018: 5.9). Each operation has increased their attention on safety culture, action close out and Critical Control arrangements. HSE System and Critical Control verification audits were conducted at each asset.

Group gold production for the December 2018 quarter was 181,996 ounces (Sep qtr: 202,218oz) at an AISC of A$973/oz (Sep qtr: A$885/oz). Using the average AUD:USD exchange rate for the quarter of 0.7178 Group AISC equated to US$698/oz – ranking Evolution as among the lowest cost gold producers in the world.

Unanticipated events late in the quarter resulted in lower than expected production and higher costs. At Cowal a stator failure led to unplanned downtime of the SAG mill in December, and at Mungari access to the high-grade Mist zone was restricted. In addition, as reported in the September Quarterly Report, Mt Rawdon is processing ore from lowgrade stockpiles. Ernest Henry, Mt Carlton and Cracow all performed in-line or better than plan.

Full year Group AISC is expected to be at the top end of the A$850 – A$900 per ounce guidance range. Year-to-date to 31 December 2018, the lower than planned achieved copper price has increased Group AISC by $11 per ounce. If the current copper price remains for the second half of FY19, Group FY19 AISC would be negatively impacted against plan by A$10 – A$15 per ounce, potentially pushing Group AISC above the top end of guidance. Opportunities to mitigate the negative impact of the copper price continue to be evaluated.

Evolution delivered operating mine cash flow of A$191.1 million (Sep qtr: A$196.9M) and net mine cash flow of A$108.5 million (Sep qtr: A$129.3M). Group capital expenditure increased to A$83.2 million in-line with plan (Sep qtr: A$67.7M). FY19

sustaining and major capital remain on track to be within guidance.

As at 31 December 2018, gross debt outstanding under the Senior Secured Syndicated Term Facility D was A$355.0 million. Net bank debt stood at A$41.1 million (Sep qtr: A$78.2M). The Group cash balance increased to A$313.6 million (Sep qtr: A$296.8M).

Ernest Henry delivered another strong performance producing 24,812oz at an AISC of A$(403)/oz generating net mine cash flow of A$54.3 million.

The major capital programs at Cowal progressed well during the quarter. Stage H material movement remains ahead of plan. The Float Tails Leach project construction was completed in December with first gold pour expected in January 2019. Ongoing work to optimise flow, gold recovery and cyanide destruction will continue in the March 2019 quarter with ramp up to full capacity expected in the June 2019 quarter.

Regulatory approvals to expand Cowal’s processing plant to 9.8Mtpa and to develop an underground mine at Mt Carlton were received during the quarter.

Successful drilling at Cowal’s GRE46 and Dalwhinnie continues to highlight the high-grade nature of this mineralised system with some outstanding results returned. As a result, an aggressive surface drilling program is under design to accelerate the delineation of high-grade mineralisation beyond the GRE46 resource outlines. Results will inform and help prioritise the underground definition drilling program.

At Mungari’s Scottish Archer project, exploration drilling returned further strong results reinforcing the developing high-grade opportunity.

March 2019 quarter gold production is expected to be similar to the December 2018 quarter.

OPERATIONS

Cowal, New South Wales (100%)

Cowal produced 58,244oz of gold at an AISC of A$1,019/oz (Sep qtr: 61,260oz, AISC A$958/oz).

Mine operating cash flow for the quarter increased to A$59.2 million (Sep qtr: 52.8M). Net mine cash flow was A$12.8 million (Sep qtr: A$24.0M) post sustaining capital of A$13.1 million and major capital of A$33.3 million. Major capital was associated with growth projects including the Stage H, Float Tails Leach (FTL) project and ongoing construction at the Integrated Waste Landform tailings facility.

Production and costs were adversely affected by a five-day unplanned shutdown due to a SAG mill breakdown in December. This had a negative impact on production of approximately 3,500 ounces. The issue has been fully rectified.

Stage H material movement remains ahead of plan.

A record quarterly plant throughput of 2,036kt was achieved. The FTL project construction was completed in December as per plan with first gold pour expected in January 2019. Ongoing work to optimise flow, gold recovery and cyanide destruction will continue throughout the current quarter with a ramp up to full capacity in the June 2019 quarter.

Regulatory approval to commence development of the GRE46 exploration decline was received during the December 2018 quarter. Contract award for the portal establishment and decline is scheduled for the March 2019 quarter with work to commence in the June 2019 quarter.

Mungari, Western Australia (100%)

Mungari produced 29,992oz of gold at an AISC of A$1,474/oz (Sep 2018 qtr: 35,120oz, AISC A$1,120/oz).

Mine operating cash flow for the quarter was A$12.7 million (Sep qtr: A$22.8M). Net mine cash flow was A$5.7 million (Sep qtr: A$17.4M) post sustaining capital of A$5.5 million and major capital of A$1.5 million.

The Frog’s Leg Underground mine produced 101kt of ore at a grade of 4.40g/t gold. Production was predominantly from the Rocket and Dwarf zones due to Mist work areas being affected by seismicity. A revised mining plan is expected to safely reestablish access to the high-grade Mist area in the March 2019 quarter.

Total development was 266m with the focus on completion of the exploration decline. Drill testing of the Banjo target zone for Frog’s Leg extensions at depth commenced in January 2019.

Following the success of Azimuth aligner tools on production drill rigs at Cracow, they will be implemented at Mungari in the March 2019 quarter to assist dilution reduction and allow access to narrower stoping areas.

The White Foil open pit Stage 3a progressed on plan. Total material movement was 1.6Mt including 349kt of ore at a grade of 1.68g/t gold. White Foil is in an operational phase of mining for the next two quarters with no capital waste movement.

A total of 389kt of ore was processed at an average grade of 2.54g/t gold. Plant utilisation was 96.4%. Throughput was impacted by planned shuts in the crushing circuit.

Cultural and environmental land surveys for the haul roads to Cutters Ridge and Stage 1 of Castle Hill were completed during the quarter with permitting to commence in the March 2019 quarter.

OPERATIONS

Mt Carlton, Queensland (100%)

Mt Carlton produced 26,101oz of payable gold during the quarter comprised of 19,489oz contained in 14,691 dry metric tonnes (dmt) of gold concentrate and 6,612oz in gold doré (Sep qtr: 26,197oz, 19,378oz in concentrate and 6,819oz gold doré). AISC decreased to A$715/oz (Sep qtr: A$831/oz).

Mine operating cash flow of A$31.1 million and net mine cash flow of A$20.9 million (Sep qtr: A$16.6M) was generated post sustaining and major capital of A$10.3 million.

A total of 202,063 tonnes of ore at 5.10g/t gold was treated. Processing plant recoveries improved to 90.9% (Sep qtr: 87.7%). Further upgrades to the plant including data capture and real time analysis for improved recoveries are planned for the March 2019 quarter.

Mining activities focussed on the development of the Stage 4 cutback. Sufficient ore stocks were generated from Stage 3 to sustain mill feed as a contingency plan during the wet season.

On 10 January 2019 Mt Carlton experienced an extreme rainfall event over a 24-hour period (including 420mm of rain recorded over 12 hours). While no significant damage occurred to site infrastructure, access to site was temporarily restricted due to road flooding. As a result of the above contingency planning, no material impact on production is expected.

Mt Rawdon, Queensland (100%)

Mt Rawdon produced 20,407oz of gold during the quarter and delivered 50,119oz for the first half of FY19 in-line with plan.

AISC increased to A$1,421/oz (Sep qtr: A$1,168). As highlighted in the September Quarterly Report, production and costs were negatively impacted due to the processing of low-grade stockpiles as a result of scheduled ore availability in the pit.

Mine operating cash flow of A$11.0 million and net mine cash flow of A$3.5 million (Sep qtr: A$11.8M) was generated post sustaining and major capital spend of A$7.5 million. The majority of the capital spend was on capital stripping and works on the Tails Storage Facility (TSF).

Ore mined was 638kt at an average grade of 0.85g/t gold. Mining activities were focused on the Stage 4 cutback until mid-October when a significant storm event resulted in a geotechnical mine slip in the southern section of the pit. Remediation work will be ongoing in the June 2019 half-year and ore will be sourced from the northern section of the pit.

A total of 836kt of ore was processed at an average head grade of 0.87g/t gold. Plant recovery of 86.9% was in-line with expectations for the ore type and plant utilisation was 95.6%.

Despite a soft quarter expected in March 2019 as access to ore in the pit is regained, Mt Rawdon remains on track to meet FY19 production guidance.

The underground mine project was approved by the Board during the December quarter and establishment work has commenced. A contract miner is expected to be appointed in the March 2019 quarter.

OPERATIONS

Cracow, Queensland (100%)

Cracow produced 22,440oz of gold at an AISC of A$1,181/oz (Sep qtr: 22,291oz, AISC A$1,286/oz).

Mine operating cash flow for the quarter was A$18.4 million. Net mine cash flow was A$11.4 million (Sep qtr: A$5.7M), post sustaining capital and major capital of A$6.9 million.

Sustaining capital of A$3.8 million comprised mainly of TSF construction, equipment replacements and infrastructure upgrades.

A total of 151kt of ore was mined at an average grade of 5.09g/t gold. Primary ore sources were the Kilkenny, Coronation and Imperial ore bodies.

The plant processed 148kt at an average grade of 5.18g/t gold, setting a monthly throughput record in December (51kt) and a six-month throughput record in the December 2018 half-year (292kt).

Ernest Henry, Queensland

(Economic interest; 100% gold and 30% copper production)[1]

Evolution’s interest in Ernest Henry delivered 24,812oz of gold and 5,325t of copper (Sep qtr: 25,638oz and 5,557t of copper) at an AISC of negative A$(403)/oz (Sep qtr: A$(617)/oz).

The cost performance continues to be exceptional with a C1 cash cost of negative A$(757)/oz after accounting for copper and silver by-product credits (Sep qtr: A$(804)/oz). Cash operating costs (C1) were comprised of A$1,078/oz and by-product credits of A$(1,835)/oz.

Copper sales in the quarter were 5,325t at an average copper price of A$8,477/t.

Mine operating cash flow for the quarter was A$58.7 million representing the gold (A$43.9 million) and by-product sales of copper (A$45.1 million) and silver (A$0.4 million) produced during the quarter net of Evolution’s contribution to operating costs of A$30.8 million. Ernest Henry generated a net mine cash flow for Evolution of A$54.3 million, post sustaining capital of A$4.4 million.

Ore mined was 1,740kt at an average grade of 0.57g/t gold and 1.07% copper. Underground development was 1,646m. Ore processed was 1,730t at an average grade of 0.57g/t gold and 1.10% copper. Gold recovery of 80.7% and copper recovery of 96.7% was achieved with mill utilisation at 91.0%.

During the quarter the New Reserves Joint Venture was formed which relates to resources outside the current mine plan to the 1200RL. Drilling below the 1200RL is scheduled for the latter part of the 2019 calendar year with a view to extend mine life.

FINANCIALS

The December 2018 quarter saw Evolution continue to invest in mine life extensions and production growth with the approval of major development projects at Cowal (Plant expansion, GRE46 underground decline and exploration drilling) and Mt Carlton (Underground mine development and plant upgrade). Despite the elevated levels of investment, all operations maintained their positive cash flow generation after meeting their operating and capital needs.

Evolution sold 188,534 oz of gold at an average gold price of A$1,730/oz (Sep qtr: 196,021 oz at A$1,662/oz). Deliveries into the hedge book totalled 37,500oz at an average price of A$1,686/oz with the remaining 151,034oz of gold delivered on spot markets at an average price of A$1,740/oz.

Evolution generated operating mine cash flow of A$191.1 million which was slightly down on the September 2018 quarter of A$196.9 million due to lower gold and copper sales offset by higher realised metal prices.

Net mine cash flow of A$108.5 million was A$20.8 million lower than the prior quarter (Sep qtr: A$129.3M) due to the planned ramp up of capital investment programs. The majority of the A$82.6 million investment capital related to major projects (A$51.0M) with the balance invested in sustaining capital (A$31.6M). Major capital expenditure items included: Cowal Stage H development, Float Tails Leach project and E46 land acquisition costs (A$33.3M); Cracow Underground mine development (A$3.1 million); Mt Carlton capital waste stripping (A$6.7M) and Underground mine development (A$1.1M); Mt Rawdon capital waste stripping (A$5.2M); and Mungari Underground development (A$1.5M). Sustaining and major capital investment remains on track to be within full year guidance ranges of A$105 – A$130 million and A$165 – A$200 million respectively.

Mt Carlton delivered an improved financial performance with A$20.9 million in net mine cash flow (Sep qtr: A$16.6M) despite increasing investment on the recently approved underground mine development.

Ernest Henry’s net mine cash flow of A$54.3 million was higher than the prior quarter (Sep qtr: A$53.8M) with increased gold and copper prices. Cracow (A$11.4M) net mine cash flow doubled the September performance due to higher gold sales and lower capital spend (Sep qtr: A$5.7M).

Income tax of A$53.3 million paid during the quarter related to the FY18 Tax Year (A$45.0M) and instalments relating to the FY19 tax year (A$8.3M). Tax instalments in the second half of the year are forecast to be between A$15.0 – A$20.0 million.

Following the A$20.0 million debt repayment during the quarter, net bank debt was reduced to A$41.4 million while unaudited gearing was at 1.4% as at 31 December 2018.

Evolution’s hedge book as at 31 December 2018 stood at 475,000oz at an average price of A$1,816/oz. During the quarter, the Company took advantage of the elevated Australian dollar gold price to hedge a further 300,000oz of production at an average price of A$1,871/oz for quarterly deliveries between July 2020 and June 2023. The additional hedging provides support to the balance sheet during a period of major capital investment while leaving the majority of production unhedged.

EXPLORATION

Exploration highlights

  • Cowal

  • Excellent drilling results continue at GRE46 and Dalwhinnie with standout intersections including: 3.2m (2.1m etw) grading 29.11g/t Au and 18.0m (11.7m etw) grading 6.73g/t Au

  • Drilling at GRE46 North intersected 16.0m (9.6m etw) grading 3.74g/t Au – potentially the upplunge extension of the resource defined further to the south

  • Mungari

  • Further exploration drilling at Scottish Archer intersected a laminated vein with visible gold which returned a very high-grade intersection of 7.0m (6.8m etw) grading 127g/t Au

  • Total drilling of 36,726m (resource definition) and 43,548m (discovery) was completed during the quarter. Evolution’s exploration tenement holdings in Australia stand at 8,140 km[2]

Cowal, New South Wales (100%)

During the quarter drill testing was completed at the GRE46, E41 and East Girral targets. A total of 13 diamond holes for 8,045m were completed with 12 holes at GRE46 and one hole at E41 (Figure 1). In addition, a followup aircore drilling program commenced at East Girral during the quarter.

EXPLORATION

Galway Regal E46 (GRE46)

Drilling continued at GRE46 and Dalwhinnie, with some intersections recording very high-grade mineralisation in the Dalwhinnie position and the GRE46 diorite outside of the current mineral resource outline (Figure 2).

Assays from the resource definition program included:

  • 0.9m (0.8m etw) grading 946g/t Au from 526m (1535DD348)

  • 46.0m (27.2m etw) grading 7.80g/t Au from 631m – Dalwhinnie intercept (1535DD348)[1]

  • 3.2m (2.1m etw) grading 29.11g/t Au from 522m (1535DD348A)

  • 18.0m (11.7m etw) grading 6.73g/t Au from 637m – Dalwhinnie intercept (1535DD348A)

  • 6.3m (5.4m etw) grading 10.70g/t Au from 311m (1535DD342)[1]

The Dalwhinnie intercepts in holes 1535DD348 and 1535DD348A are 80m apart and are believed to be in the same south plunging mineralised shoot in the Dalwhinnie position.

Following these outstanding results, an accelerated drilling program for Dalwhinnie and GRE46 resource definition drilling is being prepared and expected to commence in the March 2019 quarter.

Positive results for exploration drilling of the northern and southern extensions of GRE46 were received and included:

  • 16m (9.6m etw) grading 3.74g/t Au from 480m including 1m grading 55.8g/t Au (1535DD336)

  • ▪ 21m (14.7m etw) grading 1.04g/t Au from 276m (1535DD343)

  • 7m (5.7m etw) grading 2.60g/t Au from 138m (1535DD337)

The intersection in hole 1535DD336 is testing the northern limits of mineralisation in GRE46 and is the likely upplunge extension of mineralisation defined as a resource (MSO shape) further to the south. The underground drilling program will further delineate this extension when drill positions become available.

E41 West

Final results were returned from resource definition at E41W completed in the September 2019 quarter. Drilling focussed on infilling gaps within the current A$1,800/oz resource shell and testing for extensions. Results align well with current model grades. Samples have been dispatched for metallurgical test work.

Mungari, Western Australia (100%)

EXPLORATION

Scottish Archer

Five holes were drilled at Scottish Archer to test the extents of a high-grade zone identified in previous drilling (Figure 4). Best intercepts included:

  • 7.0m (6.8m etw) grading 127.05g/t Au from 358m (EVDD0036)

  • ▪ 4.0m (3.7m etw) grading 3.32g/t Au from 164m (EVRC0591)

Hole EVDD0036 intersected a laminated vein with visible gold that returned a very high-grade intersection of 7.0m (6.8m etw) grading 127g/t Au down-dip of a previously reported high-grade intersection of 4.0m (3.9m etw) grading 13.24g/t Au[1] . Results imply structural complexity and have extended the high-grade zone down dip. Further drilling to confirm the depth and strike extent of the high-grade zone will be completed in the March 2019 quarter.

Ora Banda

In the Ora Banda area, a system-scale exploration strategy has been implemented to test the potential for southwest oriented mineralised structures. A high-resolution gravity survey was acquired, and recent RC drilling has confirmed another southwest oriented mineralised structure approximately 200m northwest of Frontier. Best intercepts on the new structure included:

  • 6.0m (5.6m etw) grading 2.99g/t Au from 161m (EVRC0576)

  • 2.0m (1.8m etw) grading 6.32g/t Au from 21m (EVRC0578)

EXPLORATION

Resource Definition

During the quarter 17,575m of resource definition drilling was completed across four projects. Most of the drilling occurred at White Foil targeting the underground resource.

White Foil

Thirty-five holes were completed at White Foil. The purpose was to test shorter range (~20m) grade continuity by infilling high-grade zones in areas previously estimated with an Indicated or Inferred resource category. Best intercepts included:

  • 13m (10.4m etw) grading 4.98g/t Au from 310m (WFRD046W1)

  • 9.0m (7.2m etw) grading 6.77g/t Au from 279m (WFRD088)

  • 7.6m (6.0m etw) grading 6.37g/t Au from 350m (WFRD066)

  • 9.0m (7.2m etw) grading 4.94g/t Au from 187m (WFRD061)

Results to date align well with current model grades. The resource model update will be reported as part of the December 2018 Mineral Resource and Ore Reserve statement in April 2019.

Frog’s Leg

Development of the drill platform which will be utilised for drilling below the current workings has been completed. Underground drill testing of the Banjo target zone commenced early in January 2019. The program is expected to take six weeks and results are anticipated to be reported in the March 2019 quarter.

Cracow, Queensland (100%)

Resource Definition

More than 13,072m of resource definition drilling was completed with three underground diamond drills focussing on resource conversion, extensional drilling and testing theoretical underground targets. The best results were returned from the Killarney structure where mineralisation is continuing to be defined both down dip and along strike to the south of the currently defined resource. The resource model update will be reported as part of the December 2018 Mineral Resource and Ore Reserve statement in April 2019.

Cowal Section 1 Sampling Techniques and Data 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.

Prior to 2018 drill core was halved with a diamond saw in 1 m
intervals, irrespective of geological contacts. Since 2018
Sampling to lithological contacts has been implemented. 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
ALS Orange. Sample preparation 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 in this report has been drilled since 2009 and has been
oriented using accepted industry techniques at the time.
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 and
Kenometer Core Orientation tools 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.

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

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/QC Administrator monitors
the assay results for non-compliance and requests action when
necessary. Batches with CRM’s that are outside the ±2SD
acceptance criteria are_reviewed and re-assayed if definitive_
bias is determined or if re-assay will make a material difference.

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.

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

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.

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.

Homestake and Barrick.
Geology Deposit type, geological setting and
style of mineralisation.

The Cowal gold deposits (E41, E42, E46, Galway and Regal)
occur within the 40 km long by 15 km wide Ordovician Lake
Cowal Volcanic Complex, east of the Gilmore Fault Zone
within the eastern portion of the Lachlan Fold Belt. There is
sparse outcrop across the Lake Cowal Volcanic Complex
and, as a consequence, the regional geology has largely
been defined by interpretation of regional aeromagnetic and
exploration drilling programs.

The Lake Cowal Volcanic Complex contains potassium rich
calc-alkaline to shoshonitic high level intrusive complexes,
thick trachyandesitic volcanics, and volcaniclastic sediment
piles.

The gold deposits at Cowal are structurally hosted,
epithermal to mesothermal gold deposits occurring within and
marginal to a 230 m thick dioritic to gabbroic sill intruding
trachy-andesitic volcaniclastic rocks and lavas.

The overall structure of the gold deposits is complex but in
general consists of a faulted antiform that plunges shallowly
to the north-northeast. The deposits are aligned along a
north-south orientated corridor with bounding faults, the
Booberoi Fault on the western side and the Reflector Fault on
the eastern side (the Gold Corridor).

Criteria Explanation Commentary
The assumptions used for any reporting
of metal equivalent values should be
clearly stated.
Relationship between
mineralisation widths
and intercept lengths
These relationships are particularly
important in the reporting of Exploration
Results.
If the geometry of the mineralisation with
respect to the drill hole angle is known, its
nature should be reported.
If it is not known and only the downhole
lengths are reported, there should be a
clear statement to this effect (e.g.
‘downhole length, true width not known’)

Mineralisation within the drilling area is bounded by large
north-south trending structures, however it has strong
internally oblique structural controls. Drill holes are typically
oriented to optimise the angle of intercept at the target
location. All significant intercepts are reported as_down hole_
intervals unless labelled as Estimated True Widths (ETW).
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

Drill hole location plans for drilling at GRE46 are provided
below. Representative sections are provided in the body of
the report.

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

Significant intercepts reported are only those areas where
mineralisation was identified.

These assay results have not been previously reported.

All earlier significant assay results have been reported in
previous ASX announcements.

The intercepts reported for this period form part of a larger
drill program that was still in progress at the time of writing.
Remaining holes are awaiting logging, processing and
assays and future significant results will be published as
appropriate.

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.

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.

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.
Logging Whether core and chip samples have
been geologically and geotechnically
logged to a level of detail to support

estimation,
mining
studies
and
metallurgical studies.
Whether logging is qualitative or
quantitative in nature. Core (or costean,

The total length and percentage of the
relevant intersections logged.

RC drill chips and diamond core have been geologically logged
to the level of detail required for the Mineral Resource
estimation, mining studies and metallurgical studies.

All logging is both qualitative and quantitative in nature
recording features such as structural data, RQD, sample
recovery, lithology, mineralogy, alteration, mineralisation types,
vein density, oxidation state, weathering, colour etc. All holes
are photographed wet.

All RC and diamond holes were logged in entirety from collar to
end of hole.

Whether
sample
sizes
are
appropriate to the grain size of the
material being sampled.

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
insertionofblanksamples (1 in 20) orat 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.

(eg
standards,

duplicates, external laboratory checks)
and whether acceptable levels of
accuracy (i.e. lack of bias) and
precision have been established.

The sampling preparation and assaying protocol used at
Mungari was developed to ensure the quality and suitability of
the assaying and laboratory procedures relative to the
mineralisation types.

Fire assay is designed to measure the total gold within a
sample. Fire assay has been confirmed as a suitable technique
for orogenic type mineralisation. It has been extensively used
throughout the Goldfields region. Screen fire assay and
LeachWELL / bottle roll analysis techniques have also been
used to validate the fire assay techniques.

The technique utilised a 30g, 40g or 50g sample charge with a
lead flux, which is decomposed in a furnace with the prill being
totally digested by 2 acids (HCI and HN03) before the gold
content is determined by an AAS machine.

No geophysical tools or other remote sensing instruments were
utilised for reporting or interpretation of gold mineralisation.

Quality control samples were routinely inserted into the
sampling sequence and were also inserted either inside or
around the expected zones of mineralisation. The intent of the
procedure for reviewing the performance of certified standard
reference material is to examine for any erroneous results (a
result outside of the expected statistically derived tolerance
limits) and to validate if required; the acceptable levels of
accuracy and precision for all stages of the sampling and
analytical process. Typically, batches which fail quality control
checks arere-analysed.
Verification of
sampling and
assaying

The

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

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.

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

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 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.

Mineralisation at Ora Banda is hosted by southwest trending
corridors with an average dip and dip direction of 80º /320º.

Mineralisation at Scottish Archer is hosted by northwest
trending structures with an average dip and dip direction of
45º/220º or 80º /220º.

Surface 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.

Resource Definition and Exploration 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 are
followed. Prior to submission samples are retained on site and
access to the samples is 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. Whilevariouslaboratorieshave

for grade control and has returned more consistent duplicate
sample weights than a standard static cone splitter. Trials in the
exploration environment are ongoing.

Exploration has been carried out by a number of parties
including Electrum Resources NL (1985-1989), Castle Hill
Resources NL (1989-1996), Goldfields Exploration Ltd (2001)
and Cazaly Resources Ltd (2004-2008). The historical data and
database have been reviewed by Cube and is deemed to be of
acceptable quality for Mineral Resource estimation.

Significant historical work has been performed across the
Regional Tenement package by numerous parties since the
original discovery of gold in the region c.1890. Recent
exploration commenced during the 1970’s onwards and has
included exploration for base metal and gold mineralisation.
Geology Deposit type, geological setting and
style of mineralisation.

The Ora Banda and Scottish Archer prospects are located in
the northern portion of the Mungari tenements, in the Ora
Banda camp. The geology comprises Bent Tree Basalt and
Victorious Basalt. The mineralisation is associated with
structures related to the Grants Patch Fault.

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.

APPENDIX 1 – JORC CODE 2012 ASSESSMENT AND REPORTING CRITERIA

Mungari Section 2 Reporting of Exploration Results Mungari Section 2 Reporting of Exploration Results
Criteria Explanation Commentary
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

All Exploration and Resource Definition results have been
reported in the Drill Hole Information Summary in the Appendix
of this report.
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.

A substantial Exploration and Resource Definition program is
on-going at the Mungari site. Other works include field mapping
and geophysical surveys.
Further work The nature and scale of planned
further work (eg tests for lateral
extensions or depth extensions or
largescale step-out drilling).
Diagrams clearly highlighting the
areas of possible extensions, including
the main geological interpretations and
future drilling areas, provided this
information
is
not
commercially
sensitive.

Further Exploration, Near Mine Exploration and Resource
Definition work on the Mungari tenements are planned for the
remainder of FY18
