PENNY & EDNA MAY STUDY UPDATES

HIGHLIGHTS

▪ Penny Feasibility Study (Mt Magnet)

  • AISC cost reduced to A$633/oz (PFS: A$703/oz)

  • Upfront capital cost increased to A$34.5M (PFS: A$23.5M) due largely to re-allocation from operating costs to capital

  • Metallurgical Recovery increased to 95% (PFS: 92%)

  • NPV5% of A$301M @ A$2,300/oz, IRR 240%, Payback of 26 months

  • Board approval to commence project development (refer Table 5)

  • Mining commencement late June 2021 Quarter (PFS: Sep 2021 Qtr)

  • Edna May Underground Study

  • Mineral Resource updated to be:

    • 31,000,000t @ 1.1g/t for 1,000,000oz (total resource)
  • With high-grade lodes sub-total of:

    • 490,000t @ 4.5g/t for 72,000oz (high-grade lodes)
  • New Mineral Resource 22% larger than previous

  • Option study for bulk underground versus narrow vein mining is progressing, and will also include consideration of Stage 3 open pit and potential interaction

Ramelius Resources Limited ( ASX:RMS ) (“ Ramelius ”, “ the Company ”) is pleased to provide the results of the Penny Feasibility Study (Mt Magnet) and consequentially the Board’s approval to expedite the Project’s development. Also provided is an updated Mineral Resource at Edna May and associated underground and open pit mining study status, all within its portfolio of projects in Western Australia (refer Figure 9).

As a result of compelling financial outcomes from the Penny Feasibility Study, the Company has also approved a Decision-to-Mine to bring the project into production in the June 2021 Quarter, slightly earlier than contemplated by the Prefeasibility Study. Part of the decrease in AISC and increase in upfront capital is associated with allocation of costs from a “first ore” to a “commercial production” basis. This has also resulted in some of the upfront capital being brought forward into the second half of FY2021, earlier than previously anticipated (refer Table 5 - FY2021 Group Capital Expenditure).

At Edna May, infill and extensional diamond drilling has been completed and the resource model updated, with the revised Mineral Resource significantly larger than previous. Progress of the underground bulk versus high grade only mining study has continued although it is apparent that any decision to change from the current high grade lode mining method is best considered alongside the potential Stage 3 open pit study. For this reason, both underground and open pit studies will be reported on after their completion by the end of December 2020 Quarter.

PENNY GOLD PROJECT (WA) – FEASIBILITY STUDY RESULTS

Summary

Ramelius is pleased to provide the results of its Penny Feasibility Study for the development of the project located approximately 20km south of Youanmi or 170km by road south east of Mt Magnet in Western Australia. The Feasibility Study results are compared to the Pre-Feasibility Study, released to the ASX on 30 June 2020, in Table 1 below.

1 The Feasibility Study is a Production Target that contains a small proportion of Inferred Resources (9%). There is a low level of geological confidence associated with inferred mineral resources and there is no certainty that further exploration work will result in the determination of indicated mineral resources or that the production target itself will be realised.

Geology and Mineralisation

Host stratigraphy for the deposit is a sequence of steeply dipping mafic and ultramafic rocks with minor felsic intrusives. Gold mineralisation is associated with steeply east dipping, quartz-sulphide veins typically 2m to 5m in width. These quartz lodes are visually distinct and typically display sharp boundaries to the mineralisation.

The quartz veins are variably massive, laminated or brecciated with a highly variable sulphide assemblage of pyrite, pyrrhotite, galena, chalcopyrite and sphalerite. Some sulphide zones are semi-massive and can comprise 50-90% sulphide. Visible gold can be seen proximal to galena and sphalerite. Pb anomalism is significant with lode Pb grade up to 2%. Silver grade is also significantly higher than typical Archaean lode gold deposits.

A Ramelius Mineral Resource was generated in May 2020. The Penny West and North lodes are defined by 94 RC and 22 diamond drill holes for a total of 22,468m, the majority of which were angled at -60° to grid west (MGA94). All holes in the Penny North lode were completed by Spectrum Metals Ltd in 2019.

A separate small resource model was generated for the Magenta deposit using the same methodology and included 20 new Ramelius RC infill holes.

Geotechnical

Assessed ground conditions have been determined from observations of the current Penny West Pit, geological interpretation, geotechnical logging of 6 diamond holes and physical properties obtained from laboratory tests on the core.

Ground conditions in the footwall and orebody are expected to be good. The only poor domain was identified in ultramafic rocks in the hangingwall. Fortunately, the ultramafic is interpreted to be at least 20m into the hangingwall of the Penny North underground mine and on this basis should not adversely affect mining activity.

Hydrology

The existing pit lake (approximately 25,000 TDS) within the existing Penny West Pit will serve as the main source of initial water for dust suppression during the open pit phase. Drilling for water bores to identify long term make up water has already commenced. A recently drilled hole between Magenta and Penny West has yielded encouraging volumes of water (≈5,000 TDS) and is likely to be used to top up water supply for underground mining water and for use as the primary supply for the camp and ablutions. Future drill programs will continue to focus on the search for additional sources to further reduce risk.

Mining

The primary initial focus will be excavation of a 736,000bcm cutback on the existing Penny West pit to facilitate portal development in fresh rock from a position in the pit which is safely accessible. The cutback design incidentally allows recovery of 1,200t @ 15.5g/t of inferred ore. The Penny West cutback design is shown in Figure 4 below.

==> picture [420 x 487] intentionally omitted <==

Figure 4 – Penny West Pit Cutback Design

Penny North Underground Mine and will be accessed from the Penny West Pit and will ultimately be mined to a depth of 180mRL (~315m below surface). Production levels will be spaced 20m floor to floor. Ore drives will be developed to a height of 4.5m, resulting in production drill holes up to 20m in length. All holes are planned to be 76mm up holes.

5

In order to approach 100% extraction, backfilling of voids will be required. The proposed method is already deployed at the Vivien mine with Cemented Rock Fill (CRF) in every second level. CRF will use development waste material, this material generally has a particle size distribution that provides the fill with the required strength without further crushing or screening. Where possible, development waste rock will be trucked directly to “backfill” stockpiles to limit haulage of waste rock to the surface and back. Using CRF, every second production level (primary level) would be completely backfilled with the intermediate (secondary) levels remaining open with small island pillars left in-situ to provide support to the hanging wall.

The Penny West mineralisation left below the pit is generally thinner than Penny North and consequently has not been included in the current mine plan at this stage. Further drilling and evaluation of Penny West is expected during operations. A long section of the Penny North mine design is shown in Figure 5.

==> picture [471 x 277] intentionally omitted <==

Figure 5 – Penny North mine design with grey stopes to contain CRF, pink representing up-hole secondary stopes

The underground schedule is based upon a single jumbo developing at a maximum rate of 260m per month and a maximum stoping rate of 11,000t of stope ore per month from a level with each level having 2 production fronts.

The Penny Ore Reserve has been generated by standard design and evaluation processes using input appropriate to this level of study including dilution, recovery, cut-off grade and economic factors to meet JORC 2012 reporting criteria. It comprises of the Mining Inventory based on Indicated Resource. Ore Reserve is detailed in Table 3.

Metallurgy

It is planned for the Penny Project ore to be processed through the Mt Magnet Processing Plant as part of an overall feed blend. Test work has shown that high metallurgical recoveries can be achieved at the current processing grind size of nominally 175µm.

No capital modifications to the processing facility are required in order to process the Penny gold ores. Penny ores are marginally softer and the gravity circuit has been demonstrated to have a capacity well above the calculated gravity gold recovery in the Penny feed blend, and the overall gold production is below peak gold production. It should be noted that a separate study is being undertaken by Ramelius looking to expand plant capacity as a standalone project. This study would also consider any implications of the Penny ores in the feed blend.

The metallurgical modifying factors used for the Penny Feasibility Study can be summarised as:

  • Gold recovery: 95%

  • Throughput: 1.9-2.0 Mtpa

  • Operating cost: A$20.50/t

The Mt Magnet processing plant is a conventional CIL/CIP gold plant with single stage crushing, primary SAG milling in closed-circuit with a pebble crusher, and secondary closed-circuit ball milling. A centrifugal style gravity gold recovery circuit operates on a portion of the secondary milling product hydrocyclone underflow. Gravity gold concentrate is intensively leached. Cyanide leaching on the classified mill product is undertaken through two large, agitated leach tanks, two large, agitated adsorption tanks and three (of six) older Pachuca style (air agitated) adsorption tanks. Leach kinetics are improved through the addition of oxygen through the first leach tank stages of the circuit. Gold is eluted from the loaded activated carbon, it is then electrowon, calcined and smelted into gold doré as is standard practice.

The prefeasibility and feasibility testwork has been undertaken in two rounds. The first was done on six variability samples; one oxide sample from the Magenta proposed open pit deposit and five fresh samples from the proposed Penny underground deposit. Five of these were from reverse circulation (RC) drill holes and one was a diamond drill (DD) hole sample. A second round of variability testwork was undertaken on an additional five fresh Penny underground samples to further improve the understanding of the variability in the metallurgical behaviours. This has been undertaken on four RC hole samples and one additional diamond drill hole (see summary results for these samples below, along with the original two results from Spectrum Metals - SPX).

The samples tested are all within the Ore Reserve and the probable mining inventory. They have been selected as spatially representative lode intervals throughout the deposit. A single sample from the Magenta prospect (proposed shallow open pit) was selected to verify the metallurgical behaviour of the oxide ores.

Based on the metallurgical testwork, a gold recovery of 95% has been selected for the feasibility study mine optimisation and financial modelling. The recovery is based on the average of the gravity and 24-hour leach recoveries at a grind size of 150 - 175 µm. The 24-hour value better reflects the residence time of the Mt Magnet processing plant (18 – 20 hours). As might be expected, testwork for 48-hour leach and 125 µm grind size generated slightly higher recoveries.

Financial Analysis

The high grade Penny project will generate significant financial returns at the modelled gold price of A$2,300/oz and current spot prices of approximately A$2,650/oz. At an assumed price of A$2,650/oz, the project generates an AISC margin of just over A$2,000 per ounce. Table 4 below summarises some key financial data for both gold price assumptions.

When the Company released its Life of Mine plan in June 2020, the development expenditure for Penny was assumed to be incurred in the FY2022 financial year. With the expedited approval of the development of the project, the Group Capital expenditure for FY2021 can now be updated as shown below, which brings forward A$15.9M from FY2022 into FY2021 (timing adjustment only). This additional expenditure in FY21 will be funded from the Company’s own balance sheet.

Key sources of cost estimates include current open pit and underground contract mining rates from existing Ramelius sites of similar size, third party vendor quotes, recent internal capital expenditure and existing internal Ramelius operating costs:

Key differences between from the Prefeasibility Study to the Feasibility Study include:

  • Metallurgical recovery increasing from 92% to 95% following completion and analysis of metallurgical test work, increasing gold production from 230koz to 238koz and revenue from A$530M to A$547M;

  • Increased detail of underground operating costs (refinement) including a reduction in direct underground costs from A$90.3M to $86.6M;

  • Increase in the processing costs from A$20.0/t to A$20.50/t;

  • Mine operating cash flow has increased from A$361M to A$380M;

  • The increase in up front capital is largely based on moving costs from operating to upfront capital, based on commercial production levels as opposed to first ore. Total operating and capital costs (excluding royalties) have risen A$0.4M, which is an increase of only 0.2% on the PFS cost estimates; and

  • Key non-financial changes include aspects such as successful hydrological drilling for water sources and completion of the lease-wide heritage survey.

EDNA MAY UNDERGROUND – UPDATED MINERAL RESOURCE & MINING STUDY

Location & Project History

The mine is located adjacent to the town of Westonia in Western Australia, 315km east of Perth. Significant historic underground mining occurred between 1911 – 1947. Modern open pit and underground mining has taken place from 1984 to 1998 and then from 2010 to present. The deposit has produced over 1 million ounces.

Geology and Mineralisation

The deposit is well understood geologically. The Edna May Gneiss (EMG) is a metamorphosed tonalitic granitoid within a mafic-ultramafic stratigraphy. It hosts the gold mineralisation which occurs as sheeted quartz, minor sulphide veining, generally parallel to strike and less frequent larger quartz lodes/reefs which cross-cut the gneiss with a more northerly strike and westerly dip. The gneiss strikes east-west (100-120°) and dips at 50-60° to the north. It has a strike length of 1,000m, a width of 50–150m and depth extent of at least 700m. Significant background Au anomalism (0.1 - 0.5 g/t) is present, associated with alteration intensity, proximity to veining and micro-fracturing. Visible gold is frequently seen in drill core in close association with veining and gravity recovery is very high for a low-grade deposit at around 50%.

Mineral Resource Commentary

The drilling dataset and resource modelling methodology continues the methodology established by Ramelius since acquisition of the mine in late 2017. This essentially comprises of composited, topcut grade domains, OK estimation within the broader EMG domain and ID2 estimation within narrow lode domains.

The October 2020 model update changes include:

  • new infill & extensional UG diamond drilling – 75 holes for 7,390m. Mostly targeting the Jonathan & Fuji quartz reef lodes down-dip

  • depletion of underground mining to September 2020

  • extension of the Indicated and Inferred limits, reflecting additional drill density and higher gold price

Maximum depth of Indicated category is 480m and 540m for Inferred. While deep for a bulk low grade resource this is not far below current optimisation shells and nominal Stage 3 pit designs. The Edna May resource has been generated for evaluation by open pit as well as selective and bulk underground mining techniques and is reported above a 0.5 g/t Au cut-off. The high grade quartz lode resource component, included in the total Edna May resource above, is:

Attachment A: JORC Table 1 Edna May Resource

Section 1 Sampling Techniques and Data

Criteria JORC Code explanation Commentary
Sampling
techniques

Nature and quality of sampling (eg cut
channels, random chips, or specific specialised
industry standard measurement tools
appropriate to the minerals under investigation,
such as down hole gamma sondes, or
handheld XRF instruments, etc). These
examples should not be taken as limiting the
broad meaning of sampling.

Include reference to measures taken to ensure
sample representivity and the appropriate
calibration of any measurement tools or
systems used.

Aspects of the determination of mineralisation
that are Material to the Public Report.

In cases where ‘industry standard’ work has
been done this would be relatively simple (eg
‘reverse circulation drilling was used to obtain 1
m samples from which 3 kg was pulverised to
produce a 30 g charge for fire assay’). In other
cases more explanation may be required, such
as where there is coarse gold that has inherent
sampling problems. Unusual commodities or
mineralisation types (eg submarine nodules)
may warrant disclosure of detailed information.
• Sampling gold was conducted using 1m intervals collected
from reverse circulation (RC) drill holes. Surface and
underground diamond holes may be sampled along sub
1m geological contacts, otherwise 1m intervals are the
default.
• Drill hole locations were designed to allow for spatial
spread across the interpreted mineralised zone. All RC
samples were collected and split to 3-4kg samples on 1m
metre intervals. Diamond core is half cut along downhole
orientation lines. Half core is sent to the laboratory for
analysis and the other half is retained for future reference.
• Standard fire assaying was employed using a 50gm
charge with an AAS finish for all diamond, RC and RAB
samples.
Drilling
techniques
Drill type (eg core, reverse circulation, open-
hole hammer, rotary air blast, auger, Bangka,
sonic, etc) and details (eg core diameter, triple
or standard tube, depth of diamond tails, face-
sampling bit or other type, whether core is
oriented and if so, by what method, etc).
• Diamond drilling used NQ diamond core. RC drilling was
completed using 5 ¾” face sampling RC drilling hammers.
RAB holes were completed using 4” blade bits or
hammers.
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.
• All diamond core is jigsawed to ensure any core loss, if
present is fully accounted for. Recovery is generally
excellent.
• RC primary, duplicate and total sample was weighed and
graphed at the rig to check sample recovery and interval
accuracy. Any wet, contaminated or poor sample returns
are flagged and recorded in the database to flag potential
sampling bias.
• Zones of poor sample return both in RC are recorded in
the database and cross checked once assay results are
received from the laboratory to ensure no
misrepresentation of sampling intervals has occurred.
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.
• Samples are geologically logged on site by geologists.
Details on the rock type, mineralogy, fabrics and textures
are recorded.
• Drill hole logging is qualitative on visual recordings of rock
forming minerals and on estimates of mineral abundance.
Additionally a downhole Televiewer collected structural
information including contacts, folications, banding and
veining and a geophysical tool collected gamma density
and magnetic susceptibility measurements.
• All core photographed wet & dry prior to cutting
• The entire length of each drill hole is geologically logged.

16

Sub-sampling
techniques and
sample
preparation
If core, whether cut or sawn and whether
quarter, half or all core taken.
If non-core, whether riffled, tube sampled,
rotary split, etc and whether sampled wet or
dry.
For all sample types, the nature, quality and
appropriateness of the sample preparation
technique.
Quality control procedures adopted for all sub-
sampling stages to maximise representivity of
samples.
Measures taken to ensure that the sampling is
representative of the in situ material collected,
including for instance results for field
duplicate/second-half sampling.
Whether sample sizes are appropriate to the
grain size of the material being sampled.
• Core samples were sawn and half core sampled.
• RC 1m samples are split using a rig mounted cone splitter.
• All samples are pulverized prior to splitting in the
laboratory to ensure homogenous samples with 85%
passing 75um. 200gm is extracted by spatula that is used
for the 50gm charge on standard fire assays.
• Significant numbers of mineralised duplicate samples were
selected based on Arsenic grade (by handheld pXRF
analysis) and submitted. Analysis of duplicates shows
good quality.
• The sample size is considered appropriate for the type,
style, thickness and consistency of mineralization.
Quality of
assay data and
laboratory tests
The nature, quality and appropriateness of the
assaying and laboratory procedures used and
whether the technique is considered partial or
total.
For geophysical tools, spectrometers,
handheld XRF instruments, etc, the
parameters used in determining the analysis
including instrument make and model, reading
times, calibrations factors applied and their
derivation, etc.
Nature of quality control procedures adopted
(eg standards, blanks, duplicates, external
laboratory checks) and whether acceptable
levels of accuracy (ie lack of bias) and
precision have been established.
• The fire assay method is designed to measure the total
gold. The technique involves standard fire assays using a
40gm sample charge with a lead flux (decomposed in the
furnace). The prill is totally digested by HCl and HNO3
acids before measurement of the gold determination by
AAS.
• No field analyses of gold grades are completed.
Quantitative analysis of the gold content is undertaken in a
controlled laboratory environment.
• Industry best practice was employed with the inclusion of
duplicates and standards. Standards and blanks are
interrogated to ensure they lie within acceptable
tolerances. Additionally, sample size, grind size and field
duplicates were examined to ensure no bias to gold grades
exists.
Verification of
sampling and
assaying
The verification of significant intersections by
either independent or alternative company
personnel.
The use of twinned holes.
Documentation of primary data, data entry
procedures, data verification, data storage
(physical and electronic) protocols.
Discuss any adjustment to assay data.
• Ramelius personnel have inspected the diamond core to
verify the correlation of mineralised zones between assay
results and lithology, alteration and mineralization.
• A number of holes effectively replicate existing holes and
provide good correlation. Many UG holes cross, surface
drillhole locations.
• Holes are digitally logged in the field and data is collected
in auto validating spreadsheets. These sheets were loaded
into an Access database using scripting and further
validation steps.
• The responsible geologist makes the DBA aware of any
errors and/or omissions to the database and the
corrections (if required) are corrected in the database
immediately.
• No adjustments or calibrations are made to any of the
assay data recorded in the database.
Location of
data points
Accuracy and quality of surveys used to locate
drill holes (collar and down-hole 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 are picked up using accurate DGPS
survey control or picked up by the UG mine surveyor. All
down hole surveys are collected using downhole gyro
surveying techniques provided by the drilling contractors.
• All holes were picked up in Edna May local grid
coordinates.
• An accurate topographic surface has been established
from mine surveys
Data spacing
and distribution
Data spacing for reporting of Exploration
Results.
Whether the data spacing and distribution is
sufficient to establish the degree of geological
• UG diamond holes have a variable spacing as drilled on
fan patterns. Target spacing on the lodes is 30m x 20m.
• Drill spacing is sufficient to establish appropriate continuity
and classifications.

17

and grade continuity appropriate for the
Mineral Resource and Ore Reserve estimation
procedure(s) and classifications applied.
Whether sample compositing has been
applied.
• No physical compositing has been applied within
mineralised intervals.
Orientation of
data in relation
to geological
structure
Whether the orientation of sampling achieves
unbiased sampling of possible structures and
the extent to which this is known, considering
the deposit type.
If the relationship between the drilling
orientation and the orientation of key
mineralised structures is considered to have
introduced a sampling bias, this should be
assessed and reported if material.
• The drilling is orientated orthogonal to the interpreted strike
and dip of the mineralisation.
• No orientation bias is evident
Sample
security
The measures taken to ensure sample
security.
• All bagged samples are delivered via a certified freight
company to the assay laboratory in Perth, whereupon the
laboratory checks the physically received samples against
sample submission/dispatch notes.
Audits or
reviews
The results of any audits or reviews of
sampling techniques and data.
• No external audits have been completed to date.

Section 2 Reporting of Exploration Results

Criteria JORC Code explanation Commentary
Mineral
tenement and
land tenure
status
Type, reference name/number, location and
ownership including agreements or material
issues with third parties such as joint ventures,
partnerships, overriding royalties, native title
interests, historical sites, wilderness or national
park and environmental settings.
The security of the tenure held at the time of
reporting along with any known impediments to
obtaining a licence to operate in the area.
• The results reported in this report are all located on M77/88
owned by Edna May Operations Pty Ltd.
• Currently all the tenements are in good standing. There are
no known impediments to obtaining a licences to operate in
either area.
Exploration done
by other parties
Acknowledgment and appraisal of exploration
by other parties.
• Exploration and dilling by other parties has been reviewed
and used. Previous parties have completed surface and
underground diamond and RC drilling. Companies include
Westonia Mines, ACM, Catalpa and Evolution.
Geology Deposit type, geological setting and style of
mineralisation.
• Hosted by the Edna May Gneiss, a metamorphosed
granitoid with strike length of 1km, width of 140m and depth
extent of 700m and bounded by a mafic-ultramafic
stratigraphy. Mineralisation relates to widespread quartz
veining, which occurs as thin sheeted foliation parallel or
larger cross-cutting reef veins with a polymetallic sulphide
assemblage. Mineralisation forms a broad low-grade
stockwork throughout the gneiss.
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 drill holes:
o easting and northing of the drill hole collar
o elevation or RL (Reduced Level – elevation
above sea level in metres) of the drill hole collar
o dip and azimuth of the hole
o down hole length and interception depth
o hole length.
If the exclusion of this information is justified on
the basis that the information is not Material and
• Example drill holes completed, including holes with no
significant results (as defined in the Attachments) are
reported in previous announcements by Ramelius
Resources.
• Easting and northing are given in local mine coordinates
• RL is AHD
• Dip is the inclination of the hole from the horizontal.
Azimuth is reported in local grid.
• Down hole length is the distance measured along the drill
hole trace. Intersection length is the thickness of an
anomalous gold intersection measured along the drill hole
trace.

18

this exclusion does not detract from the
understanding of the report, the Competent
Person should clearly explain why this is the
case.
• Hole length is the distance from the start to the end of the
hole measured along the drill hole trace.
• No results are generally excluded from reports.
Data aggregation
methods
In reporting Exploration Results, weighting
averaging techniques, maximum and/or
minimum grade truncations (eg cutting of high
grades) and cut-off grades are usually Material
and should be stated.
Where aggregate intercepts incorporate short
lengths of high grade results and longer lengths
of low grade results, the procedure used for
such aggregation should be stated and some
typical examples of such aggregations should
be shown in detail.
The assumptions used for any reporting of
metal equivalent values should be clearly
stated.
• No exploration results are reported. Intercepts used in
resource modelling are typically defined by cutoff and/or
geological interpretation. Lower cutoff varies from 0.5 to 2
g/t based on deposit style and whether open pit or
underground mining scenario. Topcuts not generally applied
to drill intercept reporting.
• Weighted average techniques are applied to determine the
grade of the anomalous interval when geological intervals
less than 1m have been sampled.
• No metal equivalent reporting is used or applied.
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 down hole lengths
are reported, there should be a clear statement
to this effect (eg ‘down hole length, true width
not known’).
• This report relates to resources and reserves based on
existing drillhole datasets. No new exploration results are
reported. True width or relationship generally reported
where known.
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 collar locations and
appropriate sectional views.
• Example maps and sections are included.
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.
• Drill holes completed to date are generally reported in
previous releases and all material intersections are
reported.
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.
• No other exploration data that has been collected is
considered meaningful and material to this report.
Further work The nature and scale of planned further work
(eg tests for lateral extensions or depth
extensions or large-scale 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 work mainly comprises of further drilling
programmes. No details or diagrams are attached for this
announcement.

deposit.
Nature of the data used and of any
assumptions made.
The effect, if any, of alternative interpretations
on Mineral Resource estimation.
The use of geology in guiding and controlling
Mineral Resource estimation.

Description of how the geological interpretation
was used to control the resource estimates.
• The Edna May Gneiss unit forms the main mineralised
domain and grades were generated within it using
anisotropic Ordinary Kriging. Population statistics were
reviewed and appropriate topcuts and parameters applied.
Quartz reefs were constrained within interpreted lode
shapes and estimated separately.The resource model was
constructed using Micromine software.
• Grade within the domain is estimated by geological
software using Kriging and Inverse Distance within hard
bounded domains.
• Gold grade is estimated
• No non gold elements of significance
• Parent cell of 10mE x 5mN x 5mRL with sub-cells to
minimum of 1mE x 2mN x 1mRL. Parent cell estimation
only. Parent cells are pit SMU size or larger.
• Domains are statistically analysed and assigned
appropriate search directions, top-cuts and estimation
parameters. The search is aligned with the observed
geological strike and dip of the lodes. Lode domains
estimated separately.
• Samples were composited within ore domains to 2m
lengths.
• Top cuts were applied to domains after review of grade
population characteristics. Topcuts used ranged from 10 to
13 g/t for the EMG domains and 25 & 50 g/t for the high-
grade sub-domains.
• Validation includes visual comparison against drillhole
grades and comparison against previous models.

Discussion of basis for using or not using
grade cutting or capping.
The process of validation, the checking
process used, the comparison of model data to
drill hole data, and use of reconciliation data if
available.

basis or with natural moisture, and the method
of determination of the moisture content.
• Tonnages are estimated on a dry basis
Cut-off
parameters
The basis of the adopted cut-off grade(s) or
quality parameters applied.
• Cutoffs reflect the grade continuity of mineralised zones.
• Reporting cutoff is 0.5g/t reflecting economic
considerations
Mining factors or
assumptions
Assumptions made regarding possible mining
methods, minimum mining dimensions and
internal (or, if applicable, external) mining
dilution. It is always necessary as part of the
process of determining reasonable prospects
for eventual economic extraction to consider
potential mining methods, but the assumptions
made regarding mining methods and
parameters when estimating Mineral
Resources may not always be rigorous. Where
this is the case, this should be reported with an
explanation of the basis of the mining
assumptions made.
• Resources are reported on the assumption of mining by
conventional open pit mining methods or selective
underground mining of lodes or bulk underground mining
methods
• The parent block is a suitable SMU for bulked mining
scenarios.
Metallurgical
factors or
assumptions
The basis for assumptions or predictions
regarding metallurgical amenability. It is
always necessary as part of the process of
determining reasonable prospects for eventual
economic extraction to consider potential
metallurgical methods, but the assumptions
regarding metallurgical treatment processes
and parameters made when reporting Mineral
Resources may not always be rigorous. Where
this is the case, this should be reported with an
explanation of the basis of the metallurgical
assumptions made.
• Recovery is well established at 92-94%
Environmental
factors or
assumptions
Assumptions made regarding possible waste
and process residue disposal options. It is
always necessary as part of the process of
determining reasonable prospects for eventual
economic extraction to consider the potential
environmental impacts of the mining and
processing operation. While at this stage the
determination of potential environmental
impacts, particularly for a greenfields project,
may not always be well advanced, the status
of early consideration of these potential
environmental impacts should be reported.
Where these aspects have not been
considered this should be reported with an
explanation of the environmental assumptions
made.
• Operating mine
• No issues
Bulk density Whether assumed or determined. If assumed,
the basis for the assumptions. If determined,
the method used, whether wet or dry, the
frequency of the measurements, the nature,
size and representativeness of the samples.
The bulk density for bulk material must have
been measured by methods that adequately
• Density is well established

21

account for void spaces (vugs, porosity, etc.),
moisture and differences between rock and
alteration zones within the deposit.
Discuss assumptions for bulk density
estimates used in the evaluation process of
the different materials.
Classification The basis for the classification of the Mineral
Resources into varying confidence categories.
Whether appropriate account has been taken
of all relevant factors (ie relative confidence in
tonnage/grade estimations, reliability of input
data, confidence in continuity of geology and
metal values, quality, quantity and distribution
of the data).
Whether the result appropriately reflects the
Competent Person’s view of the deposit.
• The resource has been classified as Indicated or Inferred
category’s based on geological and grade continuity and
drillhole spacing and generation and likely economic
extraction
• The resource classification accounts for all relevant factors
• The classification reflects the Competent Person’s view
Audits or
reviews
The results of any audits or reviews of Mineral
Resource estimates.

No audits or reviews conducted. Previous resource
comparison models exist
Discussion of
relative
accuracy/
confidence
Where appropriate a statement of the relative
accuracy and confidence level in the Mineral
Resource estimate using an approach or
procedure deemed appropriate by the
Competent Person. For example, the
application of statistical or geostatistical
procedures to quantify the relative accuracy of
the resource within stated confidence limits, or,
if such an approach is not deemed
appropriate, a qualitative discussion of the
factors that could affect the relative accuracy
and confidence of the estimate.
The statement should specify whether it
relates to global or local estimates, and, if
local, state the relevant tonnages, which
should be relevant to technical and economic
evaluation. Documentation should include
assumptions made and the procedures used.
These statements of relative accuracy and
confidence of the estimate should be
compared with production data, where
available.
• The accuracy and confidence in the Resource is
reasonably high given the deposit style, quality and density
of drilling and sampling.
• Resources are global estimates
• Significant production data is available
