Western Mines Group Ltd (WMG or Company) ( ASX:WMG ) is pleased to update shareholders on the Company’s Nickel Exploration Strategy and the highlights of upcoming activities as we prepare for active nickel exploration programs in 2022.

Summary

Exploration is progressing well at the Company’s flagship Mulga Tank Ni-Cu-PGE Project with an ongoing Moving Loop Electromagnetic (MLEM) survey ( ASX, Moving Loop EM Survey Commences at Mulga Tank Project, 7 October 2021 ) already highlighting initial targets. The survey has completed the southern sector of the intrusion and is currently infilling additional lines across bedrock conductor targets identified before moving to the central portion of the intrusion.

WMG recently announced an acquisition to expand the project area from 113km[2] to 395km[2] , covering approximately 37km strike and the majority of the under explored Minigwal Greenstone Belt ( ASX, Acquisition to Expand Flagship Mulga Tank Ni-Cu-PGE Project, 8 November 2021 ). The new ground contains a 12km trend of interpreted ultramafic bodies on the western basal portion of the Minigwal Greenstone Belt, considered to be prospective for Ni-Cu-PGE magmatic sulphide mineralisation. Work is underway designing initial exploration programs over the new ground.

WMG is building its nickel focus and has recently completed a historical review of the Company’s second Ni-Cu-PGE project Pavarotti, near Southern Cross. This review highlights the area around Jocks Fury gossan as highly prospective and under explored. Historical rock chip samples show anomalous results of up to 0.74% Ni, 0.11% Cu and 0.22g/t Pt+Pd over 140m strike .

The area was first identified by BHP in the late 1960’s who drilled several shallow holes at Jocks Fury including H202 intersecting 4.6m at 1.28% Ni, 597ppm Cu, 293ppm Co from 42.7m to the end of hole (EOH) and H273 intersecting 16.8m at 0.78% Ni, 360ppm Cu, 285ppm Co from 12.2m, including 3.1m at 1.60% Ni, 865ppm Cu, 700ppm Co from 24.4m. These results do not appear to have been adequately tested at depth and this area was largely overlooked in subsequent exploration by Delta Gold (1985 to 1996) and Western Areas (2000 to 2014).

WMG is planning an initial site visit to the Pavarotti Project area within the next few weeks ahead of commencing field exploration programs in 2022.

Mulga Tank Project

The Mulga Tank Project comprises exploration licence E39/2132 and exploration licence applications E39/2223 and E39/2299, covering 395km[2] of the Minigwal Greenstone Belt, 190km east-northeast of Kalgoorlie. Tenement E39/2132 contains the entire Mulga Tank Dunite Intrusion, a major ultramafic intrusion, considered highly prospective for Ni-Cu-PGE magmatic sulphide mineralisation; whilst WMG’s recent acquisition of E39/2299 consolidates WMG’s position over the majority of the Minigwal Greenstone Belt, including a 12km trend of interpreted ultramafic bodies on the western basal portion of the belt.

WMG is currently undertaking a high-powered MLEM survey at Mulga Tank ( ASX, Moving Loop EM Survey Commences at Mulga Tank Project, 7 October 2021 ). To date the survey crew has completed the southern sector of the intrusion, covering an area of approximately 8.5km[2] , along 20.6 line kilometres. The crew is currently infilling additional lines across a number of bedrock conductor targets identified before moving on to the central section of the survey area. Initial imagery from the southern sector is shown in Figures 2 and 3 below, with final refined imagery expect after completion of the entire survey.

A discreet localised anomaly is seen in the CH25BZ image whilst two broader anomalies appear to be emerging in the later channel CH43BZ image. Significant historical drill hole intersections within the southern sector are highlighted on the MLEM images. It is interesting to note that a number of anomalous drill results occur around the edges of the two broader anomalies, whilst their centres remain untested.

The western anomaly in particular appears to be associated with anomalous results seen in a number of historical drill holes around its edge; including shallow BHP RC hole MRC9 that showed 6m at 0.94% Ni from 63m to end of hole , including 2m at 2.00% Ni from 67m to end of hole ; and King Eagle Resources vertical diamond hole MTD001 that showed 264m at 0.20% Ni from 68m , including 2m at 0.92% Ni from 68m.

Pavarotti Project

The Pavarotti Project comprises exploration licence E77/2478 and exploration licence application E77/2746; located approximately 50km north-northeast of Southern Cross on the western side of the Koolyanobbing Greenstone Belt.

WMG has recently completed a historical review of the Pavarotti Project which highlights the area around Jocks Fury gossan as highly prospective and likely the Company’s primary target.

Historical Exploration

The western basal ultramafic sequence of the Koolyanobbing Greenstone Belt has been explored intermittently for nickel sulphide mineralisation since the 1960s, with nickel gossans and Kambaldastyle channel hosted nickel sulphide mineralisation in komatiite ultramafic volcanics first identified by BHP.

BHP completed a series drilling programs over the North Range area of the Koolyanobbing Greenstone Belt between 1968 to 1972 which identified the Jocks Dream deposit, located between WMG’s tenements E77/2478 and E77/2746, as well as the Pavarotti and Jocks Fury prospects within WMG’s tenement E77/2746. Key significant BHP drill holes from this period include:

Jocks Dream ( outside WMG tenement area )

BKY110 15.9m at 1.64% Ni and 0.19% Cu from 32.2m inc. 4.3m at 3.38% Ni and 0.37% Cu from 42.7m
PBKY90 12.2m at 1.21% Ni and 0.13% Cu from 1.5m inc. 3.1m at 1.70% Ni and 0.30% Cu from 4.6m
PBKY105 9.8m at 1.01% Ni from 68.3m

Jocks Fury ( WMG tenement E77/2746 )

H202 4.6m at 1.28% Ni, 597ppm Cu and 293ppm Co from 42.7m
H273 16.8m at 0.78% Ni, 360ppm Cu and 285ppm Co from 12.2m inc. 3.1m at 1.60% Ni, 865ppm Cu and 700ppm Co from 24.4m

Figure 5: Pavarotti Project area

BHP recognised the komatiitic rocks were high MgO flows and had the characteristics of Kambaldastyle nickel deposits. There are three irregular zones of nickel mineralisation towards the base of the komatiite flow sequence and other isolated smaller “hanging wall” zones of mineralisation recognised in the Koolyanobbing North area, over a cumulative thickness of approximately 300m.

The North Range area was subsequently explored by Delta Gold (1985 to 1996), who largely focused on the Jocks Dream deposit (outside WMG tenement area) and after further drilling determined a resource for Jocks Dream of 78,600 tonnes at 1.13% Ni and 0.10% Cu (Lemmon, 1992) (not JORC 2012 compliant).

In 1998, Hunter Exploration, in joint venture with Delta Gold, completed further nickel focused exploration across the North Range, including rock chip sampling at Jocks Fury that showed anomalous results of up to 0.74% Ni, 0.11% Cu and 0.22g/t Pt+Pd over 140m strike .

The most recent nickel exploration across the Koolyanobbing Greenstone Belt was conducted by Western Areas (2000-2014), with the area contained within WMG’s tenements E77/2478 and E77/2746 forming one of the projects in Western Areas IPO portfolio. Like Delta Gold, Western Areas mostly focused on Jocks Dream (outside WMG tenement area), and later the Pavarotti prospect (within WMG tenement E77/2746), with little dedicated exploration at Jocks Fury before their tenements eventually expired and were relinquished.

WMG Exploration Plans

Based on the historical review WMG considers the area around the Jocks Fury gossan, within tenement application E77/2746, highly prospective for Ni-Cu-Co-PGE mineralisation, yet this area has often been overlooked and under explored by previous work. A number of the historical BHP drill holes (mostly shallow vertical holes) contain encouraging intersections of Ni-Cu-Co-PGE mineralisation that have not been adequately tested at depth.

In anticipation of the grant of E77/2746 in 2022, and the commencement of field exploration programs, WMG is planning an upcoming site visit to the project area to investigate the Pavarotti and Jocks Fury gossans and locate historical drill holes.

WMG will also extend the Company's recent ground magnetic survey within tenement E77/2478 aimed at mapping the continuation of the ultramafic sequence and basal ultramafic-granite contact passing through that tenement area.

Upon grant of tenement E77/2746, WMG intends to conduct high-power ground based electromagnetic surveys over the Jocks Fury and Pavarotti prospects, similar to that currently being employed at Mulga Tank, in order to help define drill targets at depth below the historical shallow intersections of Ni-Cu-CoPGE mineralisation within this tenement area. The targets identified through the exploration process will be drill tested.

The Company looks forward to updating shareholders on the progress of these activities in due course.

@westernmines westernmines Western Mines Group

Western Mines Group Ltd (ASX:WMG) is a mineral exploration company driven by the goal to create significant investment returns for our shareholders through exploration and discovery of high-value gold and nickel sulphide deposits across a portfolio of highly-prospective projects located on major mineral belts of Western Australia.

Our flagship project and current primary focus is the Mulga Tank Ni-Cu-PGE Project, a major dunite intrusive found on the under-explored Minigwal Greenstone Belt. Previous work shows significant evidence for a working sulphide mineral system and is considered highly prospective for Ni-Cu-PGE mineralisation.

WMG holds numerous other projects across major WA mineral belts including Melita (Au), midway between Kookynie and Leonora in the heart of the WA Goldfields and Jasper Hill (Au), with numerous prospective gold trends extending from the adjacent Lord Byron and Fish historical gold mines. The Company is also actively exploring Youanmi (Au), Pavarotti (Ni-Cu-PGE), Rock of Ages (Au), Broken Hill Bore (Au) and Pinyalling (Au).

JORC Code, 2012 Edition - Table 1

Section 1: Sampling Techniques and Data

Criteria	JORC Code explanation	Commentary
Sampling techniques	• Nature and quality of sampling (eg cut channels, random chips, or specifc 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 fre 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.	• Historical drilling is thought to have used best practise for that time • Impact Minerals (Impact) RC pre-collar drilling used a rife splitter to collect 3kg samples over 1m intervals • Impact NQ2 diamond drilling was cut in half and sampled on geological intervals to give sample weights under 3kg • Sampling was reported to be carried out under Impact protocols and QA/QC procedures as per industry best practise • Samples were crushed, dried and pulverised to produce a subsample for analysis by four-acid digest with ICP-OES fnish for base metals and AAS fnish for precious metals • Ground Moving Loop Electromagnetic (MLEM) survey being conducted by GEM Geophysics Pty Ltd an independent geophysical contractor • MLEM B-feld confguration/parameters: Confguration:Slingram and Inloop Receiver:SMARTem24 Sensor:JESSY DEEP HT SQUID B-feld (3D) Polarity:Z+Up, X+ East and Y+ North Transmitter:TTX2 - 100A/250V Loop Size:200m x 200m (single turn) Current:85A Line Spacing:200-400m Station Spacing:100m Base Frequency:0.25Hz Stacking:64-72stacks Readings:2-3 readings per station • MLEM surveys are an industry standard practise in testing the presence of bedrock conductors potentially representing mineralised sulphide bodies
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).	• Historical drilling used rotary air blast, aircore, reverse circulation and diamond drilling • Impact RC drilling used a 140mm face sampling hammer bit • Impact diamond drilling comprised HQ and NQ2 core, the core was orientated using a downhole orientation tool at the end of every run with 70% of orientations rated as “good”

Criteria	JORC Code explanation	Commentary
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 fne/coarse material.	• Diamond core and RC recoveries were logged and recorded in the database. Overall recoveries were reported at >95% with no core loss issues or signifcant sample recovery problems • Diamond core was reconstructed into continuous runs on an angle iron cradle for orientation marking. Depths were checked against the depth given on the core blocks and rod counts were routinely carried out by the drillers. RC samples were visually checked for recovery, moisture, and contamination • No sample bias issues were reported by Impact
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.	• Information on structure type, dip, dip direction, alpha angle, beta angle, texture, shape and fll material were collected and stored in Impact’s DataShed database • Logging of diamond core and RC samples recorded lithology, mineralogy, mineralisation, structural (core only), weathering, colour, and other features of the samples.

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.	• Historical drilling is thought to have used best practise for that time • Historical rock chip samples were taken as grab samples and assumed to use industry standard practise for that time
