Measured Resources Growth at Greenfields

Highlights:

  • A 12.5% growth in the Measured Resource category at the Greenfields was achieved with the addition of 8,000oz to the category.

  • The higher confidence Measured Resource category now comprises: 1.39 Mt @ 1.62 g/t for 72.7 Koz Au

  • The updated Measured Resource is contained within the 2022 optimised Greenfields Open pit design that received Mining Proposal approval in June 2022.

  • New metallurgical testwork results averaging 93.6% gold recovery exceed assumed 90.0% process recovery used for the PFS

West Australian gold explorer Focus Minerals ( ASX: FML ) ( Focus or the Company ) is pleased to announce updated Mineral Resource estimation for the Greenfields deposit, part of the Company’s 100%-owned Coolgardie Gold Project.

Greenfields is hosted by the prolifically mineralised Three Mile Sill within the Coolgardie Gold Project ( Coolgardie ). Coolgardie comprises 138km[2] of highly prospective tenements on the outskirts of the Coolgardie township in the Goldfields region (Figure 1). Focus is working towards resuming gold mining operations at Coolgardie starting with Greenfields open pit in early 2023.

Following the update of the Greenfields Mineral Resource the Companies’ total Measured, Indicated and Inferred Mineral Resources at Coolgardie now comprises:

Classification Tonnage

Au Grade
(g/t)
Au Contained
Moz
Total Measured 4.4 1.5 0.2
Total Indicated 22.7 1.9 1.4
Total Inferred 14.9 2.1 1.0
Total Mineral Resource 42.0 1.9 2.6

Commenting on the updates to the Greenfields open pit Mineral Resource, Focus Minerals’ Executive Chairman, Mr Wanghong Yang, said:

Market Announcement | Page 1 of 24

“The updated Greenfields open pit Mineral Resource including 2021 drilling highlighted Measured Mineral Resource category growth within a more efficient open pit design. This optimised pit design was recently used as a basis for mining proposal approval (refer ASX announcement dated 3 June 2022). This update clears the way to restate the Greenfields open pit Ore Reserves last updated in 2020 (refer to ASX announcement dated 22 September 2020).”

Greenfields Mineral Resource

Mineral Resource Estimation

The updated Greenfields Mineral Resource includes combined geotech/metallurgy holes that provide better definition of mineralisation at the bottom of the current optimised open pit design. Also, estimation parameters were adjusted for four generally higher-grade domains to improve localisation of the estimation better reflecting variability within the modelled domains.

The Mineral Resource for Greenfields is reported on a dry tonnage basis using 0.6g/t cut off to 230mRL. Measured Resource classification is applied to Indicated Resources falling within the 2022 optimised open pit design. Only Indicated Resources are reported outside the optimised pit design.

Classification Tonnage
(Mt)

Au Grade
(g/t)

Au Contained
Oz
Measured 1.39 1.62 72,500
Indicated 1.15 1.38 50,500
Total Greenfields Mineral Resource 2.54 1.51 123,500

The 2022 optimised open pit design has been built to efficiently mine the updated 2022 Greenfields Mineral Resource. It is noted that given space limitations (Figure 3) including:

  • nearby infrastructure,

  • tenement boundaries and,

  • geotechnical limitations

there is insufficient space to mine a larger pit at Greenfields exceeding the current optimised open pit design. As such the current 2022 pit design is the ultimate open pit design for the Greenfields deposit.

An Ordinary Kriging (OK) estimation technique was selected and variograms were modelled in Supervisor. Each domain was modelled using its own variogram and applicable top cut.

At Greenfields there are two orientations of mineralisation comprising:

  • flat south west dipping and,

  • steep south west dipping.

Given the overall bulk style of mineralisation present it is difficult to separate precisely what assays belong to each structural set where they are sampled by holes proximal to structural intersections. To address this and provide good correlation with local grade variability the Greenfield Mineral Resource estimate includes a couple of key treatments:

  1. Flats have been given priority over steep domains.

  2. A 10m distance limited soft boundary restriction was applied to steep domains. This specifically targets areas of elevated grades where the two structural sets intersect.

Comparison with the previous Mineral Resource Estimation

The 2020 Coolgardie PFS (refer to ASX announcement dated 22 Sept 2020). Described a cut off grade of 0.5g/t for the Greenfields open pit. The preceding 2020 Greenfields Mineral Resource (refer to ASX announcement dated 9 July 2020) was reported using a cut off grade of 0.8 g/t and Measured category applied to Indicated Mineral Resources within the 2017 PFS open pit design.

For the 2022 Greenfields Mineral Resource update the reporting cut off grade has been reduced to 0.6g/t in line with assessment of mining the 2022 optimised open pit and taking into account updated milling and mining assumptions.

Greenfields Metallurgy

To confirm expected metallurgical results in the remaining (98% fresh rock) Greenfields open pit Mineral Resource, two representative composite samples were compiled from diamond core. The samples were tested at ALS using conditions that simulate the Three Mile Hill processing flowsheet.

The two representative samples have delivered positive results, indicating the Greenfields ore exhibits relatively simple metallurgy suitable for processing at the Three Mile Hill plant. Summarised testwork results:

  • High gravity gold recovery averaging 70.5%;

  • Fast leach recovery; and

  • Average processing recovery rate of 93.65%.

It is noted that the 2020 Cooglardie PFS (refer to ASX announcement dated 22 Sept 2022) assumed a significantly lower processing recovery rate of 90% for the Greenfields open pit. The new representative metalurgical results provide a strong case for increasing the gold recovery rate for an updated Ore Reserve estimation.

Location and Past Production

Greenfields open pit is located 3.8km east of Coolgardie and just 400m east of the Three Mile Hill plant. The open pit was last mined in June 2013.

Greenfields open pit has been mined in a series of stages comprising:

Summary Geology and Structure

The Three Mile Sill is a differentiated layered mafic intrusion (gabbroic with dolerite chill margins). The Three Mile Sill generally intrudes mafic – high magnesium lower basalt units such as the Gleesons Basalt, Lindsays Basalt, Burbanks basalt (equivalent lower basalt units).

The Three Mile Sill is a highly competent unit and is prone to exploitation by bulk style gold bearing quartz vein stockworks. The Three Mile Sill hosts a large number of significant gold deposits/ occurrences over more than 15km general northwest strike including:

  • Greenfields,

  • Three Mile Hill,

  • CNX,

  • Lindsays,

  • Jolly Briton,

  • Patricia Jean,

  • Ada,

  • Emu Hill,

  • Mystery Mint.

The Greenfields stratigraphy is located on a south east plunging synform (Figure 4). The younging in the footwall of the deposit is to the west with a structurally controlled wedge of Black Flag Group volcaniclastics sitting above a 5 – 10m thick package of structurally interfingered/repeated Komatiite/Black Flag Group volcaniclastics with moderate to strong epidote alteration (Figure 5).

The synform is observable in the upper northwest wall of the Greenfields pit where folded black flag volcaniclastics overly bulk style greenfield mineralisation hosted by the G2 gabbro (Figure 1).

The Three Mile Sill is ~440m thick at Greenfields and sited on the steeply southwest dipping hanging wall of the Black Flag Group volcaniclastics (Figure 6). The Three Mile Sill is a differentiated layered mafic intrusion. Locally the coarsely granophyric G2 unit of the sill is located near the Black Flag sediment contact. The G2 gabbro has been pervasively overprinted by a stockwork of gold bearing quartz veins forming a bulk style gold deposit dipping steeply to the southwest. The hangingwall of the G2 gabbro unit is characterised by monotonous and relatively undeformed/unaltered Three Mile Sill gabbro and or dolerite (Figure 6).

A thrust is inferred to the southwest of Greenfields on the hangingwall of the Three Mile Sill. This thrust is interpreted to dissect an isoclinal fold hinge and juxtaposes an isoclinal antiform composed of lower basalt in the hanging wall of the Three Mile Sill (Figure 6).

Gold mineralisation at Greenfields is almost entirely hosted by the differentiated G2 gabbro unit of the Three Mile Sill over about 420m northwest strike.

The mineralisation at Greenfields averages 50m width and varies between 25 and +60m width. The mineralisation is primarily hosted by coarsely granophyric G2 gabbro near the contact with footwall Black Flag Group volcaniclastics (Figure 6).

Market Announcement | Page 10 of 24

Like CNX and Three Mile Hill, gold at Greenfields is hosted by a well-developed stockwork of 1cm to +20cm wide quartz>>chlorite>pyrrhotite>carbonate veins with trace amounts of chalcopyrite and arsenopyrite.

The dominant vein orientations in the G2 gabbro at Greenfields comprise:

  • bulk style lower grade stockworks dipping at ~35 degrees to the southwest and,

  • steeper higher grade stockworks dipping at ~65 degrees to the southwest.

  • Together the two stockworks have developed a bulk style tabular gold deposit amenable to open pit mining.

The Three Mile Hill gabbro is competent and barely deformed outside the stockwork overprinted G2 unit. Depth of weathering around the pit varies from 15 to 25m and locally to 40m down significant structures. The footwall of the Three Mile Sill is marked by a rare occurrence of Black Flag Group intermediate volcaniclastics. This sliver of volcaniclastics is flanked by thrusts with significant structural interfingering of volcaniclastics with the underlying komatiitic basalts.

Hydrothermal alteration is mostly focussed into the footwall shear zone that comprises structurally interleaved Black Flag Unit and ultramafics. In the hangingwall gabbro hydrothermal alteration closely related to mineralised stockwork development in the G2 unit of the Three Mile Sill. There is minimal alteration outside the G2 unit. The dominant alteration is sericite-silica-albite overprint on early chlorite-sericite alteration. Sulphides are predominantly hosted by or are proximal to mineralised veins.

JORC Code, 2012 Edition – Table 1

Section 1 Sampling Techniques and Data

(Criteria in this section apply to all succeeding sections.)

Criteria Explanation
Sampling
techniques

Focus Minerals Ltd (FML) RC percussion drill chips were collected at 1m intervals
via a riffle splitter to achieve a sample weight of approximately 3kg.

For FML diamond core, sample intervals are either cut on metre intervals or with
intervals selected to geological boundaries down to 10cm. Core is cut in half by
diamond bladed saw with half sent to the laboratory and half retained in the core
tray on site. Some of the diamond core has been ¼ core sampled, this is only in
the minority of cases.

Coolgardie Gold NL (CGNL) collected 1m samples or 2m composites for RC
holes, however, do not state their sub-sampling techniques.

CGNL diamond core was drilled at NQ size with an RC pre-collar. Half-core
samples were selectively taken over 1m intervals.

Gold Mines of Coolgardie (GMC) collected 1m RC samples from surface.

MPI collected 1m RC cuttings and were then passed through a trailer mounted
cyclone and stand-alone riffle splitter to provide a 4-6kg sample.

Diamond core was drilled at NQ2 size and after orienting and logging, was ½ core
sampled over the entire length of alteration zones up to a maximum of 1.5m
length.

The Redemption JV (RJV) established between companies Goldfan Ltd, Croesus
Mining NL, Matador Mining and Focus Minerals collected 1m RC samples from a
trailer mounted cyclone and riffle splitter to achieve a sample weight of 4-6kg.

Diamond core was NQ2 sized and ½ core sampled from 0.3m to a maximum of
1.5m.
Drilling techniques
Drilling included in the Mineral Resource estimate include RC face sampling
hammer or NQ size diamond core. All FML drill core was orientated by the drilling
contractor using an Ezy-mark system. Most holes were surveyed upon completion
of the drilling have either been surveyed by single-shot camera, electronic multi-
shot (EMS) or Gyroscopic methods.
Drill sample
recovery

In recent FML drilling all RC samples are drilled dry wherever possible to maximize
recovery, with water injected on the outside return to minimize dust. There have
been no recovery or sample quality issues for the FML drilling RC chips or drill
core.

Sample recovery has been recorded in the drill hole logs for the diamond holes
drilled by CGNL with no recovery issues. Historic RC drilling recovery is not
recorded.
Logging
FML drill holes were logged for the entire length of the hole.

All diamond core samples were orientated, marked into metre intervals and
compared to the depth measurements on the core blocks. Any core loss was
noted and recorded in the database. All core was logged for structure and geology
using the same system as RC. The core was photographed wet and dry one tray
at a time using a standardised photography jig.

All RC samples were geologically logged to record weathering, regolith, rock type,
colour, alteration, mineralisation, structure and texture and any other notable
features that are present.

Logging was qualitative; however, the geologists often record quantitative mineral
percentage ranges.

Historic RC and Diamond holes have been logged at 1m intervals to record
weathering, regolith, rock type, colour, alteration, mineralisation, structure and
texture and any other notable features that arepresent.

Page 13 of 24

Original drill logs have been viewed and used to validate data stored in acQuire for
a majority of the pre-Focus drilling.
Sub-sampling
techniques and
sample preparation

FML diamond core samples were taken from half core or quarter core cut using an
Almonte automatic core saw. The remainder of the core was retained in core trays.

RC samples were cone split to a nominal 2.5kg to 3kg sample weight. The
drilling method was designed to maximise sample recovery and delivery of a
clean, representative sample into the calico bag.

The samples were collected in a pre-numbered calico bag bearing a unique
sample ID. Samples were crushed to 75μm at the laboratory and riffle split (if
required) to a maximum 3kg sample weight.

FML samples have been assayed by ALS Chemex in Kalgoorlie or Perth using a
30g Fire Assay method with an AAS finish.

The assay laboratories’ sample preparation procedures follow industry best
practice, with techniques and practices that are appropriate for this style of
mineralisation. Pulp duplicates were taken at the pulverising stage and selective
repeats conducted at the laboratories’ discretion.

The sample sizes were considered to be appropriate for the type, style and
consistency of mineralisation encountered during this phase of exploration.

Analytical methods for gold analysis for much of the historical drilling are 25g –
50g Fire Assay method and 50g Aqua Regia completed at various laboratories in
Kalgoorlie and Perth.
Quality of assay
data and laboratory
tests

The assay method and laboratory procedures were appropriate for this style of
mineralisation. The fire assay technique was designed to measure total gold in the
sample.

No geophysical tools, spectrometers or handheld XRF instruments were used.

Drilling completed by Focus is subject to rigorous quality control processes in the
sampling process. Routine standards and “blanks” are inserted into the sample
strings and monitored on return from the laboratory. Any failures by these control
samples to be within the acceptable three standard deviation limits above and
below the certified values results in a string of samples around the failed sample
to be re-tested by the laboratory.

Regular reviews of the sampling were carried out by the supervising geologist and
senior field staff, to ensure all procedures were followed and best industry practice
carried out.

Very little in the way of quality control data is available from sampling of the
historical drilling that currently defines the resource. In 2002 MPI resampled some
of the CGNL diamond core with repeats showing high degree of grade variability
with a slight upgrade in mean grade.

RJV inserted a certified standard and a field blank every 20 samples, whilst the
ALS Chemex laboratory in Kalgoorlie inserted a blank or certified standard every
20 samples and a duplicate every 10 samples.
Drilling by Focus aimed to confirm the geometry of the ore envelope and grade
tenor encountered in historical drilling.
Verification of
sampling and
assaying

Significant intervals were visually inspected by company geologists to correlate
assay results to logged mineralisation.

Primary data is sent in digital format to the company’s Database Administrator
(DBA) as often as was practicable. The DBA imports the data into an acQuire
database, with assay results merged into the database upon receipt from the
laboratory. Once loaded, data was extracted for verification by the geologist in
charge of the project.

Historic holes were validated against paper copies and WAMEX reports where
possible.

No adjustments were made to any current or historic data. If data could not be
validated to a reasonable level of certainty it was not used in any resource
estimations.

Market Announcement | Page 14 of 24

Location of data
points

All co-ordinates and bearings use the MGA94 Zone 51 grid system.

FML drill collars were surveyed by DGPS base station instruments.

Most of the RC and diamond holes have down hole surveys by either Eastman
single shot camera, Electronic Multi-shot or Gyroscopic methods.

CGNL used Surtron to carry out the downhole surveying.
Data spacing and
distribution
Drilling has been conducted on 20m by 10 – 15m spaced grid on sections
orientated across strike of the ore zone at an azimuth of either 020º or 200 º and at
various dips. After mining commenced FML conducted RC Grade control drilling
on a 10m x 10m staggered grid at different pit floor levels across the
mineralisation, averaging 40m depth. Wider spaced drilling exists at depth up to as
wide as 40m by 80m.
Orientation of data
in relation to
geological structure

Drilling was designed based on known geological models, field mapping, verified
historical data and cross-sectional interpretation.

Drill holes were orientated at right angles to the strike of the deposit, with dip
optimised for drill capabilities and dip of the mineralisation.
Sample security
All samples were reconciled against the sample submission with any omissions or
variations reported to FML.
Historic sample security is not recorded.
Audits or reviews
Significant data validation was completed by consultants Hellmann and Schofield
who completed a resource estimate in 2005.

A review of sampling techniques was carried out by rOREdata Pty Ltd in late 2013
as part of a database amalgamation project. Their only recommendation was to
change the QA/QC intervals to bring them into line with the FML Laverton system,
which uses the same frequency of standards and duplicates but has them inserted
at different points within the numbering sequence.

Geology
The Greenfields deposit is located within the Greenfield sill which is an equivalent
unit of the Three Mile Sill.

From footwall to hangingwall the geology of the Greenfields open pit comprises:
Non mineralised units comprising the steeply south west dipping footwall shear zone

Ultramafic volcanics

Structurally repeated sequence of sheared ultramafics and overlying Black Flag
volcaniclastics,

Sheared Black Flag volcaniclastics.
Units hangingwal to the footwall shear zone

A syncline defined by folded Black Flag Volcaniclastics is noted at the upper
NW and SE sides of the open pit. This syncline presumably overlaid gabbro
hosted mineralisation through the central parts of the now mined open pit.

The majority of the open pit is situated on the hangingwall of the unmineralized
footwall shear zone. The Hangingwall is composed predominantly of Three
Mile Sill equivalent differentiated layered intrusion. The chill margin of the
intrusion is dolerite. The central part of the intrusion comprises variable gabbro
sub units including significantly mineralised G2 Gabbro unit.
Gold Mineralisation

Mineralisation is hosted by a quartz vein stockwork that exploits a conjugate set of
brittle-ductile fractures. The structural sets are dominantly:

Flat dipping to the south west and,

steep dipping to the south west

The structural sets host Bucky quartz veins have accessory pyrrhotite and
arsenopyrite sulphides and sometimes visible gold is observed.

Veins display crack seal textures and are commonly weakly wall rock laminated.

The wall rock to the veins is commonly bleached over 0.2 - 0-.4m intervals.

Data aggregation
methods

Mineralised intersections are reported at a 0.5g/t Au cut-off with a minimum
reporting width of 1m for RC holes and 0.2m for diamond holes, composited to
1m.
Relationship between
mineralisation widths and
intercept lengths


Holes were drilled orthogonal to mineralisation as much as possible, however the
exact relationship between intercept width and true width cannot be estimated
exactly in all cases.
Diagrams
Refer to Figures and Tables in body of the release.
Balanced reporting
All drill assay results used in this estimation are published in previous news
releases.

Historic drill hole results available on WAMEX.
Other substantive
exploration data

There is no other material exploration data to report at this time.
Further work
Final grade control drilling at Greenfields will be completed in the period July to
mid August 2022 with final results expected in the December quarter 2022.

The final phase grade control program will extend the existing RC grade control
throughout the area targeted by the V23 pit at approximatel~12m x 15m spacing.

Once compiled the new grade control data will facilitate a final pre-mining grade
control Mineral Resource estimate to be compiled.

Section 3 Estimation and Reporting of Mineral Resources

(Criteria listed in section 1, and where relevant in section 2, also apply to this section)

Criteria Explanation
Database integrity
Data was geologically logged electronically; collar and downhole surveys were
also received electronically as was the laboratory analysis results. These
electronic files were loaded into an acQuire database by either consultants
rOREdata or the company in-house Database Administrator. Data was
routinely extracted to Microsoft Access during the drilling program for validation
by the geologist in charge of the project.

FML’s database is a Microsoft SQL Server database (acQuire), which is case
sensitive, relational, and normalised to the Third Normal Form. As a result of
normalisation, the following data integrity categories exist:

Entity Integrity: no duplicate rows in a table, eliminated redundancy and chance
of error.

Domain Integrity: Enforces valid entries for a given column by restricting the
type, the format, or a range of values.

Referential Integrity: Rows cannot be deleted which are used by other records.

User-Defined Integrity: business rules enforced by acQuire and validation
codes set up by FML.

Additionally, in-house validation scripts are routinely run in acQuire on FML’s
database and they include the following checks:
Missing collar information
Missing logging, sampling, downhole survey data and hole diameter
Overlapping intervals in geological logging, sampling, down hole surveys
Checks for character data in numeric fields

The historical Greenfields drill data was validated by the Focus data
management team and the Project Geologist. This involved collaborating all
collar, downhole survey, geology and assay data with existing hardcopy material
as well as displaying the holes in three dimensions in Surpac to determine any
unusual or unlikely trends in the data so that it could be rectified before loading
into the Focus site database. This process was thorough and took a couple of
months for the team to complete.

Resource Geologist and last visited site in February 2014.
Geological
interpretation

Minor changes were made to the geological interpretation used in the July
2020 resource release were used for this mineral resource estimate and were
constructed as follows:

All available drill hole, mining data and pit mapping was used to guide the
geological interpretation of the mineralisation.

The mineralised geological interpretation was generated in Seequent Leapfrog
Geo implicit modelling software.

A total of 29 lodes were modelled. Four larger, steeper dipping (55o to SSW)
lodes were modelled, along with 25 less continuous, shallower dipping (30o to
SSW) lodes. The shallower lodes intersect the steeper lodes near surface with
the flatter lying structures given priority over the steeper dipping lodes.

Minor deviation of the lode geometry was modelled between drill holes down dip
and along strike.
Dimensions
The resource extends over a NW strike length of over 480m and includes the
~150m interval from the base of the final mined surface down to the 150mRL,
some 250m below surface. The thickness of the four steeper lodes varies from
average thickness of 20m near surface pinching to an average thickness of 3m
at depth. The flatter lying lodes vary from 1m to 8m wide have an average
thickness of 3m.
Estimation and
modelling techniques

An Ordinary Kriging (OK) estimate was run using Datamine software, following
the process below:

Drill hole samples were selected within the mineralised lodes and composited
to 1m downhole intervals, the dominant sample interval from historic drilling.
Residual samples that did not meet the minimum length criteria (less than
0.2m) of the compositing process were appended to the adjacent sample so
that all material within the wireframe was included.

The composited data was imported into Supervisor software for statistical and
geostatistical analysis.

After a review of the individual lode statistics, higher Au samples that were
outliers to the main population were “top-capped” to a selected value for each
lode. An average of 10ppm Au was used with a maximum of 15ppm Au.

Variography was modelled on data transformed to normal scores, the
variogram models were back transformed to original units before exporting.

Variography was performed on the individual lodes with larger sample
numbers ~ 150 samples. Lodes without variography shared the structure from
a nearby lode.

The back-transformed variogram models had moderate to high nugget effects
(20 to 60% of total sill), with a range from 20m to 200m for the lodes.

Estimation (via Ordinary Kriging) was into a non-rotated block model in
MGA94 grid, with a parent block size of 10 mE x 5 mN x 5 mRL – this is about
the average drill spacing in the deposit. Sub-blocking was used to best fill the
wireframes and inherit the grade of the parent block. No rotation was applied
to the orientation of the blocks.

The ellipsoid search parameters used the variogram ranges, with a minimum
of 8 and maximum of 16 samplesper block estimate was used. After the first

Market Announcement | Page 23 of 24

pass 76% of blocks had estimated. For un-estimated blocks after this first
pass, the search distance was expanded by a factor of two and the minimum
number of samples dropped to 4. In the second pass 22% of blocks
estimated. A third pass was then run with an increased search distance by a
factor of four and the same minimum number of samples. Only 2% of blocks
estimated in the third search pass.

Where the four steep lodes intersected the flat lodes a “soft boundary”
approach was taken, whereby samples were shared at the intersection up to
10m radius in the overprinted steep lodes.

The estimate was validated by visually stepping through the estimated blocks
and sample data in Datamine. Comparing the estimated block statistics with
composited sample data and generate trend (Swath) plots to ensure the
estimate was honouring the trends of the data. Also, a review of the output
parameters from the estimation process like kriging variance, negative
weights, search distances and sample numbers.
Moisture
Tonnages are estimated on a dry basis.
Cut-off parameters
The Resources for Greenfields have been reported above a 0.6g/t cut-off for the
V23 open pit design.
Mining factors or
assumptions

An existing open pit exists at Greenfields, mining would continue by cut-back
and open cut extraction.

The V23 Greenfields open pit design is considered the ultimate open pit design
for Greenfields and represents the maximum amount of open pit extraction
possible within the area available for open pit mining
Metallurgical factors or
assumptions

Metallurgical testwork has been conducted on Greenfields samples:

Historical recoveries in a variety of tests (N=13) average more than 95%gold
recovery.

Recent testwork to simulate processing at TMH on composite representative
samples (n=2) from Greenfields delivered very high gravity gold recovery
averaging 70.5% and overall average gold recovery exceeding 93.5%

MPI who mined Greenfields from Dec 2003 to Jan 2005 had an overall
reconciliation of ~96.9% of tonnes, 100.7% of grade and 101% of ounces milled
compared to mined.
Environmental factors
or assumptions

Greenfields deposit occurs in an area of previous disturbance with an open cut
pit and associated waste dump.

The Three Mile Hill Processing Plant is currently on care and maintenance, but
has all the necessary tailing facilities etc, that would allow for a restart of the
plant.
Bulk density
Bulk density test work was carried out on diamond core samples using a water
immersion method for these determinations.

Average bulk densities were applied to modelled weathering profiles.

Bulk densities of 2.07, 2.43 and 2.87 t/m³ were applied to Oxide, Transitional
and Fresh resources, respectively.
Classification
Resources have been classified as either Measured or Indicated based mainly
on geological confidence in the geometry and continuity of the lodes. In
addition, various estimation output parameters such as number of samples,
search pass, kriging variance, and slope of regression have been used to
assist in classification.

Measured resources have been reported inside the 2022 open pit design.

Indicated resources have been reported outside the 2022 open pit using the
open pit cut of 0.6g/t Au.
Audits or reviews
No external audits of the mineral resource have been conducted.
Discussion of relative
accuracy/ confidence

The mineral resource relates to global tonnage and grade estimates.
