Western Mines Group Ltd (WMG or Company) (ASX:WMG) is pleased to update shareholders on geochemical assay results recently received for reverse circulation (RC) drill holes MTRC001 and MTRC002 at the Mulga Tank Ni-Cu-Co-PGE Project, on the Minigwal Greenstone Belt, in Western Australia’s Eastern Goldfields.
WMG completed a 22 hole RC drilling program (totalling 7,035.5m) designed to systematically test the extent of the uppermost zone of shallow disseminated nickel sulphide mineralisation observed in the Company’s diamond core holes across the centre of the Mulga Tank Ultramafic Complex ( ASX, Completion of 7000m RC Drilling Program at Mulga Tank, 7 November 2023 ).
First assay results have now been received for holes MTRC001 and MTRC002 which highlight broad intersections of nickel sulphide mineralisation. Cumulatively around 50-60% of the samples from both of the holes appear to show mineralisation with elevated Ni and S, in combination with highly anomalous Cu and PGE. These results confirm the drilling was successful in targeting the uppermost zone of shallow mineralisation and bodes well for the results from the remainder of the program.

“Its great to see the first results from the RC program starting to come through. We sent just over 5,700 samples to the lab and we should see a steady flow of results over the next month or two.
The 22 hole RC program targeted a significant portion of the main body of the Complex, covering an area of approximately 2.5km x 1km in which we’d previously only drilled four diamond holes. The RC drilling dramatically increases the drilling density in this ‘core’ of the Complex and will yield extremely valuable data in testing the lateral continuity of shallow disseminated mineralisation, as well as beginning to systematically characterise the geology and geochemistry of the system.
mineralisation is working with broad zones of mineralisation identified in both holes. Around 50-60% of the samples from both holes showed the geochemical signature of mineralisation. These are positive initial results as the program looks to test a volume of some 650,000,000 cubic metres which could host significant nickel in sulphide - and hole MTRC001 was located in the southwestern corner of the area drilled so mineralisation is likely not constrained to this initial area.”
MULGA TANK RC DRILLING PROGRAM
WMG has been undertaking continuous drilling programs at the Mulga Tank Project since November 2022, with exciting exploration results demonstrating significant nickel sulphide mineralisation and an extensive nickel sulphide mineral system within the Mulga Tank Ultramafic Complex ( ASX, MTD023 Assays Confirm Discovery of Significant Nickel Sulphide System, 5 April 2023; MTD026 Assays - 840m of Nickel Sulphide Mineralisation, 30 August 2023; MTD027 Expands Mineralisation 4km Across Mulga Tank, 28 August 2023 ).
The Company recently completed a 22 hole RC drilling program designed to systematically test the lateral continuity of the shallow, uppermost zone of disseminated nickel sulphide mineralisation observed in the Company’s diamond holes MTD012, MTD022, MTD023, MTD026, MTD027 and MTD028 within the main body of the Mulga Tank Ultramafic Complex ( ASX, Completion of 7000m RC Drilling Program at Mulga Tank, 7 November 2023 ) (Figure 7).

The holes were spaced at approximately 500m x 300m and cover a 2,500m x 1,000m area across the centre of the Complex. Each hole was designed to a target depth of ~300m, which was achieved in all but three holes, for a total of 7,035.5mm - of which the top ~60m of each hole, or 1,321m in total, was mud-rotary drilling through the sand cover.
All holes were sampled at 1m intervals from the start of RC drilling (i.e. base of mud rotary) with a total of 5,721 samples delivered to the ALS laboratory in Perth for geochemical assay.
HIGH MGO ADCUMULATE DUNITE
Assay results for MTRC001 averaged 48.3% MgO and 0.16% Al2O3 portion of the hole, whilst MTRC002 averaged 46.5% MgO and 0.20% Al2O3 (volatile free) over 222m of ultramafic. Using Al2O3 as a proxy for interstitial material and MgO as a proxy for temperature, geochemical characterisation shows the host rock to be nearly entirely high-temperature, adcumulate to extremely adcumulate dunite with Al2O3 generally less than 0.5% and MgO greater than 40%.

This observation of extensive intersections of high MgO adcumulate dunite within the complex, starting essentially immediately under the sand cover, has positive implications for the targeting of large volume, low grade Type 2 Mt-Keith style disseminated nickel sulphide deposits within the Mulga Tank Complex.

EVIDENCE FOR NICKEL SULPHIDE MINERALISATION
Broad intersections of visible disseminated nickel sulphide mineralisation have frequently been observed in the Company’s diamond core drilling. This style on mineralisation is harder to see in RC drill chips but intersections of visual mineralisation were observed in the geological logging of a number of the RC holes e.g. MTRC009 where ~390m of disseminated sulphide was observed down the hole. The geochemical assay results for holes MTRC001 and MTRC002 show the geochemical signature of nickel sulphide mineralisation and demonstrate significant evidence for “live” magmatic sulphide chemical processes.
In the absence of magmatic sulphide processes nickel is incorporated into olivine during crystallisation and essentially trapped within the dunite host rock. Whereas, in “live” sulphur saturated mineral systems the nickel will partition into potentially “recoverable” nickel sulphide form. A number of elements, such as Cu and in particular PGE’s (Pt and Pd), have high affinity for sulphide (chalcophile), and in combination with S (and the S:Ni ratio) are used as geochemical indicators to confirm the presence of active magmatic sulphide processes.
The assay results for MTDRC001 and MTRC002 demonstrate a number of broad zones of highly anomalous Cu and PGE’s in combination with elevated S, and a S:Ni ratio greater than 0.5 (Figures 3 to 6).

DISCUSSION
approximately 650,000,000 cubic metres in the centre of the main body (assuming ~320m average drill hole depth and ~60m sand cover). The drilling aims to test the lateral continuity of the shallow, uppermost zone of disseminated nickel sulphide mineralisation observed in the Company’s diamond holes MTD012, MTD022, MTD023, MTD026, MTD027 and MTD028 (Figure 7). The results from this RC drilling should offer a step change in the understanding of the geology and geochemistry of the Complex and its potential to host a significant disseminated nickel sulphide deposit amenable to large scale open-pit mining.

shallow mineralisation, with numerous broad intervals of interpreted nickel sulphide mineralisation identified in the holes. Around 50-60% of the samples from both holes showed the geochemical signature of nickel sulphide mineralisation with elevated Ni and S, in combination with highly anomalous chalcophile elements Cu and PGE.
Holes MTRC001 and MTRC002 are located towards the fringe, in the southwestern corner, of the main area being tested and extend the current zone of known mineralisation (Figure 8). Hole MTRC001 located right on the edge of the drilled area highlights that mineralisation is not in anyway limited to the zone being tested and very likely extends outside this initial area. It is hoped these results bode well for the remainder of the program given that significant visible mineralisation has been observed in the likes of hole MTRC009 in the centre of the drilling.
The Company continues to believe this central area of the main body of the Mulga Tank Complex could host globally significant quantities of disseminated Mt Keith-style nickel sulphide mineralisation which could be amenable to large scale, open-pit mining operation.

MULGA TANK PROJECT
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. |
• Reverse circulation (RC) drilling was completed using standard industry best practice • Individual 1m samples were collected directly from the rig sampling system. Samples were crushed and pulverised to produce a sub- sample for analysis by either multi-element ICP-AES (ME-ICP61 and ME-ICP41), precious metals fre assay (Au-AA25 or PGM-ICP23) and loss on ignition at 1,000°C (ME-GRA05) |
| 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). |
• Reverse circulation percussion drilling rig with a 5.25inch face sampling bit |
| 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. |
• Standard drilling techniques using “best practice” to maximise sample recovery • Information not available to assess relationship between sample recovery and grade |

| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Geology | • Deposit type, geological setting and style of mineralisation. |
• The geology of the project area is dominated by the irregular shaped Mulga Tank serpentinised metadunite intrusive body measuring ~5km x 5km, hosted within metasediments, mafc to felsic schists and foliated metagranite of the northwest trending Archean Minigwal Greenstone Belt • Previous drilling intersected disseminated and narrow zones of massive nickel-copper sulphide mineralisation within the dunite intrusion • The intrusion is concealed under variable thicknesses of cover (up to 70 m in places) with the interpretation of the bedrock geology based largely on aeromagnetic data and limited drilling |
| 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: • easting and northing of the drill hole collar • elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar • dip and azimuth of the hole • down hole length and interception depth hole length. • If the exclusion of this information is justifed on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
• A listing of the drill hole information material to the understanding of the exploration results provided in the body of this announcement • The use of any data is recommended for indicative purposes only in terms of potential Ni-Cu-PGE mineralisation and for developing exploration targets |
| 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 metal equivalent values have been quoted • Results where stated have been normalised to a volatile free sample based on the LOI at 1,000°C results using the formula M(VF) = M / (100%-LOI%) |
| 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’). |
• The drillhole was oriented to intersect perpendicular to the mineralisation or stratigraphy • The relationship of the downhole length to the true width is not known |
| Diagrams | • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any signifcant discovery being reported. These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
• Appropriate maps, photos and tabulations are presented in the body of the announcement |

| 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. |
• Reporting of signifcant intersections in Table 2 • Reporting of majority of all sample results on charts within the document |
| 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. |
• Not applicable |
| 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. |
• Future exploration planned includes further drill testing of targets identifed • Exploration is at an early stage and future drilling areas will depend on interpretation of results |
