OVERVIEW

Group Total Recordable Injury Frequency (TRIF) at 31 March 2019 was 7.8 (31 Dec 2018: 7.3). Each operation continues to focus on improving its safety culture, critical control verification and action close out activities.

Group gold production for the March 2019 quarter was 175,901 ounces (Dec qtr: 181,996oz) at an improved AISC of A$925/oz (Dec qtr: A$973/oz). Using the average AUD:USD exchange rate for the quarter of 0.7123, Group AISC equated to US$659/oz – ranking Evolution among the lowest cost gold producers in the world.

Evolution today released its Annual Mineral Resources and Ore Reserves Statement as at 31 December 2018. Gold Mineral Resources increased to 14.73Moz (Dec 2017: 14.24Moz) and gold Ore Reserves increased to 7.46Moz (Dec 2017: 7.05Moz) after accounting for mining depletion of 902,000 ounces. The Cowal GRE46 underground has grown significantly with Mineral Resources increasing by 134% to 1.41Moz.

Evolution delivered operating mine cash flow of A$168.3 million (Dec qtr: A$191.1M) and net mine cash flow of A$107.8 million (Dec qtr: A$108.5M). The lower operating cash flow was driven predominantly by timing of gold (20,936 oz) and copper sales (939t) and was partially offset by higher realised metal prices. Group capital expenditure reduced to A$60.6 million (Dec qtr: A$83.2M). FY19 sustaining capital is expected to be at the bottom end of the A$105 – A$135M guidance range while major capital is expected to be in the middle of the A$165 – A$200M guidance range.

Extreme rainfall events at both Ernest Henry and Mt Carlton were exceptionally well managed with both sites delivering strong operational performances. Ernest Henry produced 22,419oz at an AISC of A$(510)/oz generating record net mine cash flow of A$59.5 million. Mt Carlton produced 26,116oz at an AISC of A$643/oz generating net mine cash flow of A$16.3 million.

Cowal also had a strong quarter with the benefits of increased recoveries from the Float Tails Leach plant contributing to the increase in production to 64,117oz at and AISC of A$1,000/oz. Net mine cash flow was A$15.9 million after spending total capital of A$35.9 million on projects which will deliver a pathway to increase Cowal’s annual production from 250koz to over 300koz.

The contract for the underground exploration decline was awarded during the quarter with development commencing in March and drilling expected to commence in the September 2019 quarter. Surface drilling targeting extensions to Cowal’s GRE46 and Dalwhinnie underground deposits continues to highlight the high-grade nature of this mineralised system with further outstanding results returned during the quarter.

On 25 February 2019 Evolution acquired a 19.9% stake in Tribune Resources Limited (ASX:TBR) for a cash consideration of A$41.3 million. Tribune’s major asset is its interest in the East Kundana operation adjacent to Evolution’s Mungari mine.

Subsequent to the end of the quarter, on 1 April 2019, Evolution entered into an earn-in joint venture agreement with Enterprise Minerals Limited (ASX:ENT) over the Murchison exploration project. Murchison is a large, early stage gold exploration project covering ~750km[2 ] in the Murchison region of central Western Australia.

As at 31 March 2019, gross debt outstanding under the Senior Secured Syndicated Term Facility D was A$330.0 million. Net bank debt stood at A$74.2 million (Dec qtr: A$41.1M). The Group cash balance was A$255.9 million (Dec qtr: A$313.6M).

June 2019 quarter gold production is expected to be in the range of 190,000 – 195,000 ounces.

OPERATIONS

Cowal, New South Wales (100%)

Cowal produced 64,117oz of gold at an AISC of A$1,000/oz (Dec qtr: 58,244oz, AISC A$ 1,019/oz). Mine operating cash flow for the quarter was A$51.8 million (Dec qtr: A$59.2M). Net mine cash flow increased to A$15.9 million (Dec qtr: A$12.8M) post sustaining capital of A$8.3 million and major capital of A$27.6 million. Major capital was associated with growth projects including the Stage H cutback and construction pre-works of the Integrated Waste Landform tailings facility.

The Stage H cutback remains on track with material movement ahead of schedule.

A record plant throughput of 1,100tph was achieved during March. Total throughput for the quarter of 1,913kt was impacted by a planned shut down for the mill upgrade project.

The Float Tails Leach circuit was commissioned during the quarter and delivered increased recoveries of 4.6% in the month of March. Activities in the June quarter will focus on ramping up to full capacity and optimising the circuit.

The contract for the Warraga underground exploration decline was awarded during the quarter with development commencing in March. The initial drill program is 36,000m over 15 months with drilling expected to commence in the September 2019 quarter.

Mungari, Western Australia (100%)

Mungari produced 24,966oz of gold at an AISC of A$1,521/oz (Dec 2018 qtr: 29,992oz, AISC A$1,474/oz).

Mine operating cash flow for the quarter was A$10.4 million (Dec qtr: A$12.7M). Net mine cash flow was A$2.5 million (Dec qtr: A$5.7M) post sustaining and major capital investment of A$7.9 million.

Production and costs were negatively impacted by availability of high-grade ore from the Frog’s Leg underground mine which produced 55kt of ore at a grade of 3.82g/t gold. Production was mainly from the Rocket and Dwarf ore zones. The higher-grade Mist work areas were redeveloped during the quarter with stoping to commence in April 2019. Underground mine production was also impacted by lower stoping rates due to constraints on the mining fronts in the Rocket zone with mining following a geotechnical sequence and requiring higher volumes of paste placement.

Total development was 633m with the focus on Mist. A new 3D scanning tool was fully implemented in the development of the Mist footwall drives. The data captured from this tool is being used to proactively manage ground support performance and capability.

A Stage 1 drill program testing the Banjo target zone for Frog’s Leg extensions at depth was completed. Stage 2 has been approved and is scheduled to commence in April 2019.

White Foil open pit total material movement was 1,869kt including 462kt of ore at a grade of 1.57g/t gold. Stripping continues to decline with a strip ratio of 3:1 during the quarter.

A total of 409kt of ore was processed at an average grade of 2.01g/t gold. Plant utilisation was 88%. Throughput and utilisation were impacted by a shutdown during the quarter.

OPERATIONS

Mt Carlton, Queensland (100%)

Mt Carlton produced 26,116oz of payable gold during the quarter comprised of 19,258oz contained in 12,507 dry metric tonnes (dmt) of gold concentrate and 6,859oz in gold doré (Dec qtr: 26,101oz, 19,489oz in concentrate and 6,612oz gold doré). AISC decreased to A$643/oz (Dec qtr: A$715/oz).

Mine operating cash flow of A$22.5 million and net mine cash flow of A$16.3 million (Dec qtr: A$20.9 million), was generated post sustaining and major capital of A$6.3 million.

Multiple significant rainfall events experienced during the quarter were exceptionally well managed enabling the operation deliver another strong performance. Total recorded rainfall in the March quarter was extreme at 1,095mm.

A total of 191kt of ore at 5.48g/t gold was treated. Processing plant recoveries declined slightly to 89.2% (Dec qtr: 90.9%) due mostly to lower water quality following the heavy rain events. Ongoing upgrades to the plant through the use of data capture and real time analysis on recoveries are expected to improve performance going forward.

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

Mt Rawdon, Queensland (100%)

Mt Rawdon produced 20,124oz of gold during the quarter. AISC decreased to A$1,316/oz (Dec qtr: 20,407oz, A$1,421/oz).

Mine operating cash flow of A$9.8 million and net mine cash flow of A$6.2 million (Dec qtr: A$3.5M) was generated post sustaining and major capital spend of A$3.7 million. The majority of the capital spend was on open pit stripping and the Tailings Storage Facility buttress.

Ore mined was 1,124kt at an average grade of 0.72g/t gold. Remediation work on the south-west section of the pit continued during the quarter with the majority of ore feed coming from lower-grade stockpiles as planned. A significant rainfall event also delayed access to higher-grade material in the northern end of the pit. During this period, a major primary and secondary crusher shutdown was completed.

A total of 800kt of ore was processed at an average grade of 0.88g/t gold. Plant recovery of 88.6% was in-line with expectations based on ore type. Plant utilisation was 94.4%.

Higher-grade material in the northern end of the pit is scheduled to be accessed in the June 2019 quarter. Mt Rawdon remains on track to meet FY19 production guidance.

Work continued on the underground project with the appointment of a mining contactor and the placement of orders for long-lead items.

OPERATIONS

Cracow, Queensland (100%)

Cracow produced 18,158oz of gold at an AISC of A$1,310/oz (Dec qtr: 22,400oz, AISC A$1,181/oz).

Mine operating cash flow for the quarter was A$13.2 million. Net mine cash flow was A$7.5 million (Dec qtr: A$11.4M), post sustaining capital of A$2.7 million and major capital of A$3.1 million.

Sustaining capital was comprised mainly of resource definition drilling and the replacement of capital equipment.

A total of 125kt of ore was mined at an average grade of 4.69g/t gold. Primary ore sources were the Kilkenny, Coronation and Imperial ore bodies. Continued strong development performance resulted in 1,047m of operating development which offset lower planned stoping tonnes in the quarter.

Stoping efforts have focussed on reducing dilution during a period of transition to narrower stopes. Drill and blast design changes have led to a significant improvement in performance in this area.

The plant continued to achieve a strong throughput performance with143kt processed at an average grade of 4.36g/t gold.

FINANCIALS

The March 2019 quarter saw all operations continue their consistent position of being cash flow positive after meeting all operating and capital investment programs. Despite the slightly lower gold and copper production, net mine cash flow of A$107.8 million was in-line with the December 2018 quarter of A$108.5 million.

During the quarter Evolution returned A$59.3 million to shareholders via the fully franked interim dividend of 3.5 cents per share for the half-year to 31 December 2018 and invested A$41.3 million to acquire 11.05 million shares, or a 19.9% stake, in Tribune Resources Limited.

Evolution sold 167,598oz of gold at an average gold price of A$1,798/oz (December 2018 qtr: 188,534oz at A$1,730/oz). Deliveries into the hedge book totalled 37,500oz at an average price of A$1,691/oz with the remaining 130,098 oz of gold delivered on spot markets at an average price of A$1,828/oz.

Evolution generated operating mine cash flow of A$168.3 million which was down on the December 2018 quarter of A$191.1 million. This was driven predominantly by timing of gold (20,936oz) and copper sales (939t) and was partially offset by higher realised metal prices.

Capital investment was A$60.5 million during the March quarter, comprising A$47.0 million on major projects and A$13.5 million on sustaining capital.

Cowal delivered an improved financial performance with A$15.9 million in net mine cash flow (December 2018 qtr: A$12.8 million) while Ernest Henry delivered a record quarterly net mine cash flow of A$59.5 million (December 2018 qtr: A$54.3 million). Mt Rawdon also had an improved performance with A$6.2 million of net mine cash flow (December 2018 qtr: A$3.5 million).

Mineral Resources and Ore Reserves

Evolution today announced the outcome of its annual Mineral Resource and Ore Reserve estimates (refer to ASX release “Annual Mineral Resources and Ore Reserves Statement” dated 17 April 2019).

Gold Mineral Resources increased by 480,000 ounces to 14.73 million ounces after accounting for mining depletion of 902,000 ounces. This increase was driven by an addition at Cowal of 1.34 million ounces post mining depletion. Copper Mineral Resources increased by 36,000 tonnes to 982,000 tonnes after accounting for mining depletion.

Gold Ore Reserves increased by 410,000 ounces to 7.46 million ounces after accounting for mining depletion of 902,000 ounces. This increase was driven by an addition at Cowal of 834,000 ounces post mining depletion. Copper Ore Reserves decreased by 26,000 tonnes to 538,000 tonnes after accounting for mining depletion.

The Company remains committed to operating a sustainable business that prospers through the cycle and has used an unchanged and conservative gold price assumption of A$1,350 per ounce (US$980/oz)[1] and a copper price assumption of A$6,000 per tonne (US$4,350/t) to estimate Group Ore Reserves.

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.

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.

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.

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.

Specification of the grid system used.
Quality and adequacy of topographic

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.

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

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).

Sampling of gold mineralisation at Mungari was undertaken
using diamond core (surface) and reverse circulation (RC) drill
chips.

All drill samples were logged prior to sampling. Diamond drill
core was sampled to lithological, alteration and mineralisation
related contacts, whilst RC samples were collected at 1m
downhole intervals. Sampling was carried out according to
Evolution protocols and QAQC procedures which comply with
industry best practice. All drill-hole collars were surveyed using
a total station theodolite or total GPS.

The sampling and assaying methods are appropriate for the
orogenic mineralised system and are representative for the
mineralisation style. The sampling and assaying suitability was
validated using Evolution’s QAQC protocol and no instruments
or tools requiring calibration were used as part of the sampling
process.

RC drilling was sampled to obtain 1m samples using a static
cone splitter from which 3 to 5 kg was crushed and pulverised
to produce a 30g to 50g subsample for fire assay. Diamond
drillcore sample intervals were based on geology to ensure a
representative sample, with lengths ranging from 0.2 to 1.2m.

Surface diamond drilling was half core sampled. All diamond
core samples were dried, crushed and pulverised (total
preparation) to produce a 30g to 50g charge for fire assay of Au.
A suite of multi elements are determined using four-acid digest
with ICP/MS and/or an ICP/AES finish for some sample
intervals.
Drilling techniques Drill type (eg core, reverse circulation,
open-hole hammer, rotary air blast,
auger, Bangka, sonic, etc.) and details
(e.g. core diameter, triple or standard
tube, depth of diamond tails, face-
sampling bit or other type, whether core
is oriented and if so, by what method,
etc.).

RC sampling was completed using a 4.5” to 5.5” diameter face
sampling hammer. Diamond holes from surface were
predominantly wireline NQ2 (50.5mm) or HQ (63.5mm) holes.

All diamond core from surface core was orientated using the
reflex (act II or ezi-ori) tool.
Drill sample recovery Method of recording and assessing
core and chip sample recoveries and
results assessed.
Measures taken to maximise sample
recovery and ensure representative
nature of the samples.

Whether
a
relationship
exists
between sample recovery and grade
and whether sample bias may have
occurred due to preferential loss/gain of
fine/coarse material.

RC drilling sample weights were recorded for selected sample
intervals and monitored for fluctuations against the expected
sample weight. If samples were below the expected weight,
feedback was given promptly to the RC driller to modify drilling
practices to achieve the expected weights.

All diamond core was orientated and measured during
processing and the recovery recorded into the drill-hole
database. The core was reconstructed into continuous runs on
a cradle for orientation marking. Hole depths were checked
against the driller’s core blocks.

Inconsistencies between the logging and the driller’s core depth
measurement blocks are investigated. Core recovery has been
acceptable. Surface drilling recoveries were generally excellent
with the exception of oxide zones however these rarely fell
below 90%.

Measures taken to maximise sample recovery include
instructions to drillers to slow down drilling rates or reduce the
coring run length in less competent ground.

Analysis of drill sample bias and loss/gain was undertaken with
the Overall MineReconciliationperformancewhere available.
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.

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.
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.

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.

(eg

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.

The twinning of holes is not a common practice undertaken at
Mungari. The face sample and drill hole data with the mill
reconciliation data is of sufficient density to validate
neighbouring samples. Data which is inconsistent with the
known geology undergoes further verification to ensure its
quality.

All sample and assay information is stored utilising the acQuire
database software system. Data undergoes QAQC validation
prior to being accepted and loaded into the database. Assay
results are merged when received electronically from the
laboratory. The geologist reviews the database checking for the
correct merging of results and that all data has been received
and entered. Any adjustments to this data are recorded
permanently in the database. Historical paper records (where
available) are retained in the exploration and mining offices.

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

material.

Mineralisation at Frog’s Leg is hosted within a number of steeply
dipping NNW-SSE structures that are vertical or dipping steeply
(~80 degrees) to the west. Surface and underground drilling
intersect the mineralisation at an angle to minimise bias.

Mineralisation at 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.

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
Resources Australia Ltd who was a precursor company to La
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 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 Frog’s Leg deposit is located in the southern portion of the
Kundana mining area, within the Achaean Norseman-Wiluna
greenstone belt of the Eastern Goldfields Province. The
Kundana gold deposits are structurally related to the Zuleika
