OVERVIEW

Group Total Recordable Injury Frequency (TRIF) at 30 September 2019 was 9.3 (30 June 2019: 8.3). Evolution conducted safety resets across all its operations during the quarter to refocus the Company’s efforts on improving safety performance.

Group gold production for the September 2019 quarter was 191,967 ounces (Jun qtr: 194,886oz) at an AISC of A$1,018/oz (Jun qtr: A$915/oz). Using the average AUD:USD exchange rate for the quarter of 0.686, Group AISC equated to US$698/oz – which continues to rank Evolution among the lowest cost gold producers in the world.

Evolution delivered record mine operating cash flow and net mine cash flow of A$278.7 million and A$207.4 million respectively (Jun qtr: A$215.2M; A$152.2M). Mine capital expenditure was A$71.3 million (Jun qtr: A$63.0M).

Standout operational performances for the quarter:

  • Cowal produced a record 75,807oz at an AISC of A$885/oz generating record net mine cash flow of A$89.9 million

sulphidation epithermal gold mineralisation and has significant potential to provide mine life extensions at Mt Carlton.

As at 30 September 2019, gross debt under the Senior Secured Term Facility D was A$275.0 million (30 June 2019: A$300.0M). The group cash balance increased to A$366.7 million, after paying a record cash dividend of A$102.1 million. The Company’s net cash position increased to A$91.7 million (30 Jun 2019: net cash of A$35.2M).

FY20 Group AISC guidance has been increased by A$50 per ounce to A$940 – A$990 per ounce. Revised metal price assumptions (gold A$2,100/oz and copper A$8,400/t) account for A$20/oz of the increase due to higher royalty payments and lower by-product credits. The remaining A$30/oz increase is due to a revised mine plan at Mt Rawdon after further pit wall instability in the September quarter. This requires additional waste movement and will restrict access to higher grade ore for the remainder of FY20. Group production guidance of 725,000 – 775,000 ounces is unchanged. Evolution continues to generate sector leading cash margins per ounce.

OPERATIONS

Cowal, New South Wales (100%)

Cowal produced 75,807oz of gold at an AISC of A$885/oz (Jun qtr: 67,878/oz, AISC A$1,002/oz).

Mine operating cash flow for the quarter was A$114.5 million (Jun qtr: A$ 68.5M). Net mine cash flow increased to a record A$89.9 million (June qtr: A$34.9M) post sustaining capital of A$3.4 million and major capital of A$21.2 million. Major projects investment was predominantly related to the plant expansion and pre-works construction of the Integrated Waste Landform (IWL) tailings facility.

Upgrades to the processing plant remain on track with throughput continuing to increase with a new record of 2,094kt for the quarter. Plant recovery was 83.6%. Average recoveries from the Float Tails Leach circuit for the September quarter increased to 6.3%.

Processed grade is expected to average between 0.9 – 1.0g/t for the remainder of FY20 as Stage G is depleted early in the December quarter and stockpiled ore then becomes the source feed.

The Warraga underground exploration decline has reached 1,635 metres of lateral development and continues to achieve higher than scheduled rates of advance. Underground drilling commenced during the quarter with 8,621 drill metres achieved from two underground drill rigs.

Mungari, Western Australia (100%)

Mungari produced 30,738oz of gold at an AISC of A$1,351/oz (Jun qtr: 30,457oz, AISC A$1,242/oz).

Mine operating cash flow for the quarter was A$18.6 million (Jun qtr: A$17.9M). Net mine cash flow was A$16.2 million (Jun qtr: A$10.2M) post sustaining and major capital investment of A$2.4 million.

The Frog’s Leg underground delivered a consistent feed of high-grade material and produced 103kt of ore at a grade of 3.67g/t gold (June qtr: 97kt at 3.84g/t gold).

Total development of 340 meters was reduced in line with plan and focused on establishing remnant zones in the upper Mist and Rocket areas. The new mining method in the Mist has now been fully implemented and is delivering consistent results.

White Foil open pit total material movement was 1,900kt with ore mined of 441kt grading of 1.88g/t gold. Ore was sourced from both Stage 3a and 3b.

A total of 452kt of ore was processed at an average grade of 2.30g/t gold. Plant throughput was above plan with a monthly record of 160kt in September (equating to an annualised rate of 1.92Mt) resulting from the continued focus on operational and maintenance improvements.

Final Secretary’s Environmental Assessment Requirements were received for the proposed underground mining operation. The State Significant Development Environmental Impact Statement and associated MOD16 Environmental Assessment for the final approval of the full underground operation has also commenced.

OPERATIONS

Mt Carlton, Queensland (100%)

Mt Carlton produced 20,877oz of payable gold during the quarter comprised of 17,907oz contained in 13,141 dry metric tonnes (dmt) of gold concentrate and 2,970oz in gold doré (Jun qtr: 28,232oz production comprised of 21,334oz in concentrate and 6,898oz gold doré).

All-in Sustaining Costs increased to A$1,301/oz (Jun qtr: A$744/oz) as a result of lower than expected tonnes and grade mined which was associated with mining on the hinge section of the orebody where boundaries of mineralisation are less predictable. Production is expected to remain low, and costs elevated, in the December 2019 quarter. Higher planned tonnes and grade mined in the second half of FY20 is expected to see production increase and costs decline.

Mine operating cash flow of A$40.1 million and net mine cash flow of A$12.8 million (Jun qtr: A$30.8M) was generated post sustaining capital of A$11.5 million and major capital of A$15.8 million.

A total of 212kt of ore at 4.11g/t gold (Jun qtr: 218kt at 5.15g/t) was treated with recoveries averaging 88.0%.

Open pit mining activities focused on development of Stage 3 and 4. The underground access portal was established during the quarter approximately three weeks ahead of plan. Development of the decline is progressing well.

Mt Rawdon, Queensland (100%)

Mt Rawdon produced 19,250oz of gold during the quarter at an AISC of A$1,748/oz (Jun qtr: 24,404oz, A$1,065/oz).

Net mine cash flow of A$8.5 million (Jun qtr: A$10.2M) was generated post sustaining and major capital spend of A$6.0 million. The majority of the capital spend was on open pit stripping and construction of the tailings storage facility buttress.

Ore mined was 972kt at an average grade of 0.68g/t gold (Jun qtr: 1,204kt at 0.86 g/t).

A total of 819kt of ore was processed at an average grade of 0.83g/t gold (Jun qtr: 763kt at 1.11 g/t). Plant recovery was 88.2% (Jun qtr: 89.6%). Plant utilisation was 97.9%.

Mt Rawdon was adversely impacted by instability of the western wall in the September quarter. The wall was temporarily stabilised with an in-pit buttress using a remote dozer. Longer term stabilisation of the western wall will require reducing the wall slope ° to approximately 38° from the current angle of 45 . This will restrict access to that part of the pit and result in lower total material mined in FY20. The grade of ore processed for the remainder of the financial year will be approximately 10-15% lower than originally planned while stockpiled ore is processed until access to higher grade ore in the western wall is regained.

This is expected to result in a reduction in FY20 gold production of 10,000 – 15,000 ounces, reducing FY20 guidance to 80,000 – 85,000 ounces at an AISC of A$1,490 – A$1,540 per ounce (original guidance of 90,000 – 100,000oz at A$1,210 – A$1,260/oz).

Cracow, Queensland (100%)

Cracow produced 21,917oz of gold at an AISC of A$1,307/oz (Jun qtr: 18,095oz, AISC A$1,329/oz).

Mine operating cash flow for the quarter was A$23.1 million. Net mine cash flow was A$13.9 million (Jun qtr: A$11.5M), post sustaining capital of A$4.9 million and major capital of A$4.3 million.

Sustaining capital comprised mainly of resource definition drilling and tailings storage facility construction costs.

A total of 113kt of ore was mined at an average grade of 6.63g/t gold. Primary ore sources were the Baz, Coronation and Imperial ore bodies.

Stoping was primarily focused on smaller, highergrade stoping areas, requiring rapid turnover and a focus on reducing stope dilution. The work to improve stope dilution commenced in the previous quarter has resulted in a strong grade performance for the quarter.

A processing plant shutdown was completed in the quarter as planned with the next shutdown due in the March 2020 quarter. Cost saving initiatives have been undertaken in the process plant with a view to reducing unit costs while maintaining plant performance.

FINANCIALS

The September 2019 quarter was exceptional with record mine operating cash flow of $278.7 million, which was 30% higher than the June quarter of A$215.2 million. This was achieved through both increased gold sales and a higher realised gold price.

Evolution sold 205,188oz of gold at an average gold price of A$2,111/oz during the quarter (Jun qtr: 190,810oz at A$1,858/oz). Deliveries into the hedge book totalled 25,000oz at an average price of A$1,676/oz with the remaining 180,188oz of gold delivered on spot markets at an average price of A$2,171/oz.

Evolution also generated a record net mine cash flow of A$207.4 million after a total of A$71.3 million of capital was invested. This consisted of A$26.9 million in sustaining capital and $44.4 million in major project capital.

Cowal and Ernest Henry each continue to be first-rate assets with both sites achieving record net mine cash flows during the quarter (Cowal A$89.9 million; Ernest Henry A$66.1 million). Similarly, both Mungari and Cracow achieved increased cash generation relative to the June quarter with A$16.2 million and A$13.9 million net mine cash flows respectively (Jun qtr: A$10.2 million; A$11.5 million) as a result of increased gold production and sales.

All sites have continued to generate positive cash flow after meeting their operating and capital expenditure needs.

Cue Project earn-in joint venture

Evolution has entered into an earn-in joint venture agreement with Musgrave Minerals Limited (ASX:MGV) (“Musgrave”) over the Cue exploration project. Cue is located in the Murchison Province of central Western Australia which hosts a gold endowment in excess of 30 million ounces. The Cue project is approximately 50km south of Evolution’s Murchison joint venture with Enterprise Metals Limited (ASX:ENT) (Figure 6) and is prospective for Archaean greenstone gold deposits.

The Cue joint venture covers a prospective mineralised trend, which includes Musgrave’s Lena and Break of Day resources to the south. Large parts of the fertile trend are poorly tested and extend under younger lake cover which is potentially obscuring mineralisation. The prospectivity of these tenements is demonstrated by Musgrave’s drilling results released to the ASX on 3 December 2018 in the announcement entitled “Diamond Drilling Confirms Significant Gold Discovery at Lake Austin North” with intersections including:

  • 242m grading 1.0g/t gold from 61m (18MODD008) including: ▪ 45m grading 3.3g/t gold from 70m

  • 94m grading 2.2g/t gold from 156m (18MORC057) including:

  • 52m grading 3.8g/t gold from 198m

  • 11m grading 8.7g/t gold from 208m

  • 4m grading 8.0g/t gold from 239m

Key terms of the agreement:

  • Musgrave will retain 100% ownership of areas surrounding the Lena and Break of Day resources, and the Mainland Option area (Figure 7)

  • Evolution will subscribe for 18.6 million shares (4.59%) of Musgrave for a cash consideration of A$1.5 million with the newly issued shares priced at 30 day vwap

  • Evolution may earn a 75% interest in the project area (Figure 7) by spending A$18 million over a fiveyear period, with a minimum spend commitment of A$4 million over two years

EXPLORATION

  • Evolution will determine the exploration program and budget during the earn-in period with Musgrave to operate the project during the minimum spend period

  • On completion of the earn-in, each party is to fund its pro-rata share of expenditure

  • Subject to a decision to mine, Musgrave may elect for Evolution to fund its share of development costs, repayable with interest from commercial production

EXPLORATION

Key terms of the agreement are:

  • Initial cash payment to Basin Gold of A$2.0 million on grant of the Mineral Development License (MDL)

  • Evolution to earn a 70% interest by sole funding A$7.0 million of exploration expenditure over a twoyear period

  • Once the earn-in is met, either party has the option to elect for Basin Gold’s 30% interest to be sold to Evolution for a consideration of A$4.5 million and a 10% Net Profit Interest (NPI) on any production above 100koz of gold

Cowal Section 1 Sampling Techniques and Data

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 technique 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.

Criteria Explanation Commentary
• 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.
Sub-sampling
techniques and
sample preparation
If core, whether cut or sawn and
whether quarter, half or all core taken.
If non-core, whether riffled, tube
sampled, rotary split, etc. and whether
sampled wet or dry.
For all sample types, the nature, quality
and appropriateness of the sample
preparation technique.
Quality control procedures adopted for
all sub-sampling stages to maximise
representivity of samples.
Measures taken to ensure that the
sampling is representative of the in-situ
material collected, including for instance
results for field duplicate/second-half
sampling.
Whether sample sizes are appropriate
to the grain size of the material being
sampled.

Diamond Core is cut with a diamond saw or chisel. Core is cut
to preserve the bottom of hole orientation mark and the top half
of core is always sent for analysis to ensure no bias is
introduced.

In 2003 Analytical Solutions Ltd conducted a Review of Sample
Preparation, Assay and Quality Control Procedures for Cowal
Gold Project. This study, combined with respective operating
company policy and standards (North Ltd, Homestake, Barrick
and Evolution) formed the framework for the sampling, assaying
and QAQC protocols used at Cowal to ensure appropriate and
representative sampling.

Results per interval are reviewed for half core samples and if
unexpected or anomalous assays are returned an additional
quarter core may be submitted for assay.
Quality of assay data

The nature, quality and appropriateness
of
the

Nature of quality control procedures
adopted
(e.g.
standards,
blanks,
duplicates, external laboratory checks)

SGS West Wyalong and ALS Orange are utilised as primary
sources of analytical information. Round robin checks are
completed regularly between the two laboratories. Both labs
operate to international standards and procedures and take part
in the Geostatistical Round Robin inter-laboratory test survey.
The Cowal QA/QC program comprises blanks, Certified
Reference Material (CRM), inter-laboratory duplicate checks,
and grind checks.

1 in 30 fine crush residue samples has an assay duplicate. 1 in
20 pulp residue samples has an assay duplicate.

Wet screen grind checks are performed on 1 in 20 pulp residue
samples. A blank is submitted 1 in every 38 samples, CRM’s
are submitted 1 in every 20 samples. The frequency of repeat
assays is set at 1 in 30 samples.

All sample numbers, including standards and duplicates, are

pre-assigned by a QA/QC Administrator and given to the
sampler on a sample sheet. The QA/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.
Verification of
sampling and
assaying

The
verification
of
significant
intersections by either independent or
alternative company personnel.
The use of twinned holes.
Documentation of primary data, data
entry procedures, data verification and
data storage (physical and electronic)
protocols.
Discuss any adjustment to assay data

No dedicated twinning drilling has been conducted for this drill
program.

Cowal uses DataShed software system to maintain the
database. Digital assay results are loaded directly into the
database. The software performs verification checks including
checking for missing sample numbers, matching sample
numbers, changes in sampling codes, inconsistent “from-to”
entries, and missing fields. Results are not entered into the
database until the QA/QC Administrator approves of the results.
A QA/QC report is completed for each drill hole and filed with
the log, assay sheet, and other appropriate data. Only the

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.

extent of the mineralised geological zones. All drilling prior to
2018 is sampled at 1 m intervals down hole. Lithological based
sampling was implemented in 2018 with a maximum sample
length of 1m and a minimum sample length of 0.3m to avoid
samplingacrossgeological boundaries.

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.

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).

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.

Most diamond core drilled from surface was half core sampled
and the remaining half was retained. In the oxide zone, where
cutting can wash away samples, some surface holes were full
core sampled.

All RC samples were split by a cone or a riffle splitter and
collected into a sequenced calico bag. Any wet samples that
could not be riffle split were dried then riffle split.

Sample preparation of RC and diamond samples was
undertaken by external laboratories according to the sample
preparation and assaying protocol established to maximise the
representation of the Mungari mineralisation. Laboratories
performance was monitored as part of Evolution’s QAQC
procedure. Laboratory inspections were undertaken to monitor
the laboratories compliance to the Mungari sampling and
sample preparation protocol.

The sample and size (2.5kg to 4kg) relative to the particle size
(>85% passing 75um) of the material sampled is a commonly
utilised practice for effective sample representation for gold
deposits within the Eastern Goldfields of Western Australia.

Quality control procedures adopted to maximise sample
representation for all sub-sampling stages include the collection
of field and laboratory duplicates and the insertion of certified
reference material as assay standards (1 in 20) and the
insertion of blank samples (1 in 20) or at the geologist’s
discretion. Coarse blank material is routinely submitted for
assay and is inserted into each mineralised zone where
possible. The quality control performance was monitored as part
of Evolution’s QAQC procedure.

The sample preparation has been conducted by commercial
laboratories. All samples are oven dried (between 85°C and
105°C), jaw crushed to nominal <3mm and if required split by a
rotary splitter device to a maximum sample weight of 3.5kg as
required. The primary sample is then pulverised in a one stage
process, using a LM5 pulveriser, to a particle size of >85%
passing 75um. Approximately 200g of the primary sample is
extracted by spatula to a numbered paper pulp bag that is used
for a 50g fire assay charge. The pulp is retained and the bulk
residue is disposed of after two months.

Measures taken to ensure sample representation include the
collection of field duplicates during RC drilling at a frequency
rate of 5%. Duplicate samples for both RC chips and diamond
core are collected during the sample preparation pulverisation
stage. A comparison of the duplicate sample vs. the primary
sample assay result was undertaken as part of Evolution’s
QAQC protocol. It is considered that all sub-sampling and lab
preparations are consistent with other laboratories in Australia
and are satisfactory for the intended purpose.

The sample sizes are considered appropriate and in line with
industry standards.

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

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

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 Boomer is hosted within a steeply dipping
NNW-SSE structure that is vertical or dipping steeply (~70
degrees) to the west. Surface and underground drilling intersect
the mineralisation at an angle to minimise bias.

Drilling along the Picante Trend is planned to intersect the
structure in an orientation that does not introduce sample bias.

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 test for alternate 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. While various laboratories have
been used, the chain of custody and sample security protocols
have remained similar.
Audits or reviews The results of any audits or reviews
of sampling techniques and data.

Optiro completed an audit for the 2018 Mineral Resources
update, with no material issues identified.

The Mungari geology and drilling database was reviewed by
acQuire in December 2015 and no material issues were
identified.

Oscillating cone splitter has been in use for RC sampling at all
prospects. Data collected has returned more consistent
duplicate sample weights than a standard static cone splitter.

Exploration done by
other parties
Acknowledgment and appraisal of
exploration by other parties.

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.

The initial discovery of Frog’s Leg was made by Mines and

Mancha Resources Australia Pty Ltd. The deposit was
discovered in 2000 as a result of following up on regional
anomalism identified through rotary air blast (RAB) and aircore
drilling. La Mancha was acquired by Evolution in August 2015.

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 Picante Trend which includes the Picante prospect is
located on the eastern margin of the Kintore Tonalite, NE of the
Castle Hill deposit. Mineralisation is shear hosted on the
contact between the Kintore tonalite and an ultramafic.

The Boomer prospect 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 Boomer prospect is
located on the sheared contact between the Black Flag Group
turbidites and andesites and andesitic volcaniclastic rocks of
Black Flag Group.
Drill hole Information A summary of all information material
to the understanding of the exploration
results including a tabulation of the
following information for all Material
drillholes:
o easting and northing of the drillhole
collar
o elevation or RL of the drillhole collar
o dip and azimuth of the hole
o downhole length and interception
depth
o hole length.

Refer to the drill hole information table in the Appendix of this
report.
Data aggregation
methods
In reporting Exploration Results,
weighting
averaging
techniques,
maximum
and/or
minimum
grade
truncations (e.g. cutting of high grades)
and cut-off grades are usually material
and should be stated.

Where
aggregate
intercepts
incorporate short lengths of high-grade
results and longer lengths of low-grade
results, the procedure used for such
aggregation should be stated and some
typical examples of such aggregations
should be shown in detail.
The assumptions used for any
reporting of metal equivalent values
should be clearly stated.

Intercept length weighted average techniques, minimum grade
truncations and cut-off grades have been used in this report.

At Boomer composite grades of > 1 g/t have been reported.

Composite lengths and grade as well as internal significant
values are reported in Appendix.

No metal equivalent values are used.
Relationship between
mineralisation widths
and intercept lengths
These relationships are particularly
important in the reporting of Exploration
Results.
If the geometry of the mineralisation
with respect to the drill hole angle is
known, its nature should be reported.
If it is not known and only the
downhole lengths are reported, there
should be a clear statement to this
effect (e.g. ‘downhole length, true width
_not known’) _

At Boomer, the assay results are reported as down hole
intervals with further structural interpretation ongoing to
determine accurate true widths.

For prospects where reliable estimated true widths can be
calculated these have been included along with down hole
measurements.
Diagrams Appropriate maps and sections (with
scales) and tabulations of intercepts
should be included for any significant
discovery being reported. These should

reported exploration results are provided either below or in the
body of this report.

include, but not be limited to a plan view
of drill hole.
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 (e.g. tests for lateral
extensions or depth extensions or
largescale step-out drilling).
