The Company’s internal modelling work was reviewed by independent consultants ERM. The Mulga Tank March 2025 Mineral Resource (Tables 1 and 2) at a 0.20% Ni cut-off grade is estimated to be: Indicated 565 million tonnes grading 0.28% Ni, 134ppm Co, 104ppm Cu, 18ppb Pt+Pd S:Ni 1.0 Inferred 1,403 million tonnes grading 0.27% Ni, 129ppm Co, 73ppm Cu, 17ppb Pt+Pd S:Ni 0.9 Total Resource 1,968 million tonnes grading 0.27% Ni, 131ppm Co, 82ppm Cu, 17ppb Pt+Pd S:Ni 0.9 Representing contained metal values of: Indicated Contained 1.6Mt Ni, 76Kt Co, 59Kt Cu and 327Koz Pt +Pd Inferred Contained 3.8Mt Ni, 181Kt Co, 102Kt Cu and 748Koz Pt +Pd Total Contained 5.3Mt Ni, 257Kt Co, 161Kt Cu and 1,075Koz Pt + Pd WMG believes the Mulga Tank March 2025 Mineral Resource represents the largest nickel sulphide deposit in Australia and is likely in the top 10 nickel sulphide resources of the world. Final assay results were received for deep diamond hole MTD029 (EIS3) during the period (ASX, Over 1,200m of Sulphide Mineralisation in MTD029 (EIS), 19 February 2025). Geochemical assay results for the hole show four broad zones of disseminated nickel mineralisation with elevated Ni and S, in combination with highly anomalous Cu and PGE: MTD029 689m at 0.27% Ni, 133ppm Co, 71ppm Cu, 19ppb Pt+Pd from 108m 168m at 0.23% Ni, 130ppm Co, 99ppm Cu, 22ppb Pt+Pd from 866m 266m at 0.34% Ni, 146ppm Co, 86ppm Cu, 37ppb Pt+Pd from 1,192m 124m at 0.32% Ni, 126ppm Co, 50ppm Cu, 27ppb Pt+Pd from 1,534m Cumulative 1,247m at 0.28% Ni, 134ppm Co, 76ppm Cu, 24ppb Pt+Pd from 108m with S:Ni 1.0 The results show strong evidence for an extensive magmatic nickel sulphide mineral system with a number of richer mineralised intersections seen down the hole (within the overall broader zones): MTD029 58m at 0.34% Ni, 138ppm Co, 108ppm Cu, 30ppb Pt+Pd from 204m inc. 8m at 0.48% Ni, 147ppm Co, 168ppm Cu, 35ppb Pt+Pd from 210m and inc. 10m at 0.40% Ni, 172ppm Co, 351ppm Cu, 61ppb Pt+Pd from 232m 19m at 0.44% Ni, 209ppm Co, 246ppm Cu, 64ppb Pt+Pd from 378m inc. 8m at 0.54% Ni, 250ppm Co, 371ppm Cu, 81ppb Pt+Pd from 389m that inc. 1m at 1.56% Ni, 548ppm Co, 0.12% Cu, 0.2g/t Pt+Pd from 395m 10m at 0.38% Ni, 167ppm Co, 91ppm Cu, 50ppb Pt+Pd from 568m 18m at 0.32% Ni, 141ppm Co, 70ppm Cu, 22ppb Pt+Pd from 700m 32m at 0.33% Ni, 142ppm Co, 48ppm Cu, 34ppb Pt+Pd from 1,002m 24m at 0.34% Ni, 132ppm Co, 113ppm Cu, 26ppb Pt+Pd from 1,262m ASX:WMG www.westernmines.com.au 2 ASX RELEASE | QUARTERLY ACTIVITIES REPORT MARCH 2025 126m at 0.42% Ni, 153ppm Co, 72ppm Cu, 45ppb Pt+Pd from 1,326m inc. 12m at 0.57% Ni, 181ppm Co, 96ppm Cu, 0.1g/t Pt+Pd from 1,326m that inc. 2m at 1.09% Ni, 242ppm Co, 189ppm Cu, 0.3g/t Pt+Pd from 1,334m and inc. 34m at 0.50% Ni, 160ppm Co, 68ppm Cu, 54ppb Pt+Pd from 1,416m 20m at 0.46% Ni, 163ppm Co, 109ppm Cu, 32ppb Pt+Pd from 1,550m 13m at 0.41% Ni, 126ppm Co, 29ppm Cu, 54ppb Pt+Pd from 1,639m Initial metallurgical test work on material from diamond hole MTD029 (EIS3) continued during the quarter with the first results received from the Phase 2 test work trials. The Company continued to be corporately active on a number of fronts during the period. After the end of the quarter, the Company was notified it had been successful in both its applications in Round 31 of the Exploration Incentive Scheme (EIS) and granted two awards, totalling $440,000, to fund further drilling at the Mulga Tank Ni-Cu-PGE Project, under the WA State Government’s Co-funded Exploration Drilling Program. Field reconnaissance continued at a number of the Companies gold projects including Jasper Hill and Youanami. PROJECT OVERVIEW Figure 1: Map of WMG project locations ASX:WMG www.westernmines.com.au 3 ASX RELEASE | QUARTERLY ACTIVITIES REPORT MARCH 2025 MULGA TANK The Mulga Tank Project comprises exploration licences E39/2132, E39/2134 and E39/2223 and exploration licence application E39/2299, covering the Minigwal Greenstone Belt, 190km east-northeast of Kalgoorlie. The Minigwal Greenstone Belt is a NNW trending linear sequence of predominantly mafic and ultramafic lithologies; it is very under explored due to the presence of shallow sand cover and presents a “frontier” exploration opportunity for major Ni-Co-Cu-PGE and orogenic gold deposits. Exploration results from the Company’s various drilling programs at the Mulga Tank Project over the last two years have demonstrated significant nickel sulphide mineralisation and an extensive nickel sulphide mineral system within the Mulga Tank Ultramafic Complex. WMG has undertaken a combination of both diamond and reverse circulation (RC) drilling. With this two pronged approach, RC is used to infill and prove up the extent of shallow disseminated nickel sulphide mineralisation, defined by the Company’s JORC Exploration Target modelling (ASX, Mulga Tank JORC Exploration Target, 5 February 2024), whilst the diamond drilling program continues to test deeper targets for basal massive sulphide. MINERAL RESOURCE ESTIMATE Since the initial Exploration Target estimate, the Company has completed two further phases of RC drilling totalling 36 holes for 11,536m. Results from all the drilling to date have recently been incorporated into a block model that identifies a significant mineralised zone in the main body of the Mulga Tank Complex. This mineralised zone was reported as a Mineral Resource Estimate, in accordance with JORC 2012 (ASX, Mulga Tank Mineral Resource Over 5Mt Contained Nickel - Update, 10 April 2025). The Mulga Tank March 2025 Mineral Resource (Tables 1 and 2) at a 0.20% Ni cut-off grade is estimated to be: Indicated 565 million tonnes grading 0.28% Ni, 134ppm Co, 104ppm Cu, 18ppb Pt+Pd S:Ni 1.0 Inferred 1,403 million tonnes grading 0.27% Ni, 129ppm Co, 73ppm Cu, 17ppb Pt+Pd S:Ni 0.9 Total Resource 1,968 million tonnes grading 0.27% Ni, 131ppm Co, 82ppm Cu, 17ppb Pt+Pd S:Ni 0.9 Representing contained metal values of: Indicated Contained 1.6Mt Ni, 76Kt Co, 59Kt Cu and 327Koz Pt +Pd Inferred Contained 3.8Mt Ni, 181Kt Co, 102Kt Cu and 748Koz Pt +Pd Total Contained 5.3Mt Ni, 257Kt Co, 161Kt Cu and 1,075Koz Pt + Pd WMG believes the Mulga Tank March 2025 Mineral Resource represents the largest nickel sulphide deposit in Australia and is likely in the top 10 nickel sulphide deposits in the world in terms of total resources of contained nickel metal.

The block model was divided into three geological domains, the sand cover, a narrow oxidised zone and then dunite containing disseminated sulphide mineralisation. The Mineral Resource Estimate is reported for the dunite domain only and nickel within the oxidised domain is specifically excluded from the reported results. The block model (Figure 2) used a parent block size of 50m x 50m x 10m (being approximately half the minimum drill spacing). Drill hole assay compositing was done at 2m with a top-cut of the 99th percentile nickel assay value of 6,958ppm Ni applied to the raw sample data. Inverse Distance Weighting (IDW2) estimation was performed using multiple passes at 250m, 400m and 800m search radius incorporating a minimum three drill holes. The first pass distance was determined from variography results for nickel (250m) and sulphur (300m). >0.43% Ni 0.27% Ni <0.12% Ni Figure 2: Mulga Tank Parent Block Model for the dunite domain Outline of main Mulga Tank dunite body, viewed from south looking north, coloured by Ni% Two zones with closer drill hole spacing within the parent block model were identified and wireframed to define the resource classification boundaries. The first zone, with drill holes nominally spaced at 200m x 200m (and approximately corresponding to a first pass of 280m with minimum three drill holes), was defined as the Total Resource and classified as Inferred (Figure 3). Within this Total Resource, a second zone with drill holes nominally spaced at 100m x 100m (approximately corresponding to a first pass of 140m with minimum three drill holes) was classified as Indicated. Blocks within the mineralisation domain, but outside of the Indicated and Inferred classification boundaries, were categorised as Unclassified (Figure 4).

ERM is of the opinion that the input data is sound, and the interpretation and methodology used to generate the Mineral Resource Estimate is reasonable and acceptable by industry standards, for the type and style of mineralisation. ERM are satisfied the data, interpretation and methodology support the reporting of a Mineral Resource Estimate in accordance with the JORC Code (2012). MTD029 (EIS3) GEOCHEMICAL ASSAY RESULTS Final geochemical assay results for hole MTD029 (EIS3) were received during the period (ASX, Over 1,200m of Sulphide Mineralisation in MTD029 (EIS), 19 February 2025). The results show prospective high-temperature adcumulate-extreme adcumulate dunite host rock down the length of the hole, averaging 47.9% MgO and 0.39% Al2O3 (volatile free), over a cumulative 1,563m, for the logged unweathered ultramafic portion of the hole. The assay results show four broad zones of disseminated nickel mineralisation with elevated Ni and S, in combination with highly anomalous Cu and PGE: MTD029 689m at 0.27% Ni, 133ppm Co, 71ppm Cu, 19ppb Pt+Pd from 108m 168m at 0.23% Ni, 130ppm Co, 99ppm Cu, 22ppb Pt+Pd from 866m 266m at 0.34% Ni, 146ppm Co, 86ppm Cu, 37ppb Pt+Pd from 1,192m 124m at 0.32% Ni, 126ppm Co, 50ppm Cu, 27ppb Pt+Pd from 1,534m Cumulative 1,247m at 0.28% Ni, 134ppm Co, 76ppm Cu, 24ppb Pt+Pd from 108m with S:Ni 1.0 The results show strong evidence for an extensive magmatic nickel sulphide mineral system with a number of richer mineralised intersections seen down the hole (within the overall broader zones): MTD029 58m at 0.34% Ni, 138ppm Co, 108ppm Cu, 30ppb Pt+Pd from 204m inc. 8m at 0.48% Ni, 147ppm Co, 168ppm Cu, 35ppb Pt+Pd from 210m and inc. 10m at 0.40% Ni, 172ppm Co, 351ppm Cu, 61ppb Pt+Pd from 232m 19m at 0.44% Ni, 209ppm Co, 246ppm Cu, 64ppb Pt+Pd from 378m inc. 8m at 0.54% Ni, 250ppm Co, 371ppm Cu, 81ppb Pt+Pd from 389m that inc. 1m at 1.56% Ni, 548ppm Co, 0.12% Cu, 0.2g/t Pt+Pd from 395m 10m at 0.38% Ni, 167ppm Co, 91ppm Cu, 50ppb Pt+Pd from 568m 18m at 0.32% Ni, 141ppm Co, 70ppm Cu, 22ppb Pt+Pd from 700m 32m at 0.33% Ni, 142ppm Co, 48ppm Cu, 34ppb Pt+Pd from 1,002m 24m at 0.34% Ni, 132ppm Co, 113ppm Cu, 26ppb Pt+Pd from 1,262m 126m at 0.42% Ni, 153ppm Co, 72ppm Cu, 45ppb Pt+Pd from 1,326m inc. 12m at 0.57% Ni, 181ppm Co, 96ppm Cu, 0.1g/t Pt+Pd from 1,326m that inc. 2m at 1.09% Ni, 242ppm Co, 189ppm Cu, 0.3g/t Pt+Pd from 1,334m and inc. 34m at 0.50% Ni, 160ppm Co, 68ppm Cu, 54ppb Pt+Pd from 1,416m 20m at 0.46% Ni, 163ppm Co, 109ppm Cu, 32ppb Pt+Pd from 1,550m 13m at 0.41% Ni, 126ppm Co, 29ppm Cu, 54ppb Pt+Pd from 1,639m ASX:WMG www.westernmines.com.au 8 ASX RELEASE | QUARTERLY ACTIVITIES REPORT MARCH 2025 Figure 5: Assay results for WMG deep diamond holes within the Mulga Tank Ultramafic Complex The deeper portion of the hole showed strong evidence for the system to host a massive sulphide component, with frequent sulphide veining and numerous zones of large sulphide segregations, in a very “active” and sulphide saturated magma assemblage. These observations continue to validate the Company’s assumptions and exploration thesis. The visual and geochemical assay results from the hole provide further insights into the overall architecture of the Mulga Tank Complex, with some very interesting features emerging. They again support the conclusion that the Mulga Tank Complex is still relatively “in-situ”, sitting right way up and flat lying with a moderate ~20-30o dip towards the east. The western portion of the Complex appears to be uplifted, by ~500m or more, and implies that the two prospective “cloud sulphide” mineralised zones can be targeted at much shallower depths towards the west. The Company will look to revisit the western margin, targeting these zones for both basal massive sulphide and/or shallow +100m intervals of >0.4% Ni material for a “starter pit” scenario of the larger open-pitable resource. ASX:WMG www.westernmines.com.au 9 ASX RELEASE | QUARTERLY ACTIVITIES REPORT MARCH 2025 UPDATE ON METALLURGICAL TEST WORK The upper portion of diamond hole MTD29 (EIS3) was drilled with larger diameter HQ core to provide material for initial metallurgical test work of the shallow disseminated mineralisation. Six intervals of mineralisation, totalling 62m downhole length and approximately 113kg weight, were selected from the top 150m to 300m depth of the hole. Each of the 6 intervals of core were crushed and sampled on a length weighted basis to form a 50kg bulk sample, representative of the hole. The remaining crushed material was kept as individual intervals and placed in cold storage. To date a series of 12 different rougher flotation tests have been conducted on the bulk sample material, with the Company recently advancing to Phase 2 of the metallurgical program. Each flotation tests different factors including grind size (53um to 150um) and various reagents, with and without desliming of fines. Incorporating the sighter results, further tests have been designed and planned to approximate a processing flowsheet. This enhanced scope of work is one of the Company’s principal focuses for the first half of 2025 and results will be announced to shareholders when available.

The project is located approximately 80km southeast of Laverton and covers part of the poorly exposed Merolia Greenstone Belt, a NNW trending belt, up to 20km wide, that can be traced over 110km in a SSE direction from the Burtville Mining Centre. The project area is lightly explored, but is contiguous to the historical producing mines of Lord Byron (160,000oz at 1.0g/t Au) and Fish (87,000oz at 4.1g/t Au) owned by Brightstar Resources (ASX:BTR). Jasper Hill is the Company’s primary gold project containing a mineralised gold trend over 3km strike. The Company has previously completed field reconnaissance work involving geological mapping, high-resolution ground magnetic survey and locating historical drill collars and registered aboriginal heritage sites. Following the grant of P39/6267, the Company completed various fieldwork campaigns involving ground magnetics (extending current coverage), ground gravity and soil and rock chip sampling. Results from the ground gravity survey were processed during the quarter. Further soil sampling, geological mapping and ground geophysics is planned at the project during the current quarter.

The project is located 70km southwest of Sandstone and lies on the eastern side of the Youanmi Greenstone Belt, along the major Youanmi Shear. The tenement is located 7km from the historic Youanmi Gold Mining Centre, which has produced over 600,000oz of gold since its discovery in the late 1800’s, currently owned by Rox Resources (ASX:RXL) and Venus Metals (ASX:VMC). The area has seen a resurgence in exploration activity with the recent discovery of the high-grade Penny North (ASX:RMS) and Grace (ASX:RXL) deposits along the Youanmi Shear. The Company has undertaken various fieldwork campaigns involving field reconnaissance, ground magnetics and ground gravity targeting the historical Deep Well, and interesting structural displacement along the major Youanmi Shear. Further ground gravity surveying over the Deep Well Prospect was completed during the period, increasing resolution to 100m x 100m spacing over the target area. Figure 9: Historical Deep Well RAB drilling and WMG ground gravity survey points ASX:WMG www.westernmines.com.au 13 ASX RELEASE | QUARTERLY ACTIVITIES REPORT MARCH 2025 MELITA The Melita Project comprises exploration licence E40/379, covering an area of approximately 105km2. The project is located 20km south-southeast of Leonora and to the north of the Kookynie, Niagara and Orient WellButterfly gold mining centres, in the heart of the WA Goldfields. The Kookynie area has seen recent upswing in exploration, with WMG’s Melita Project surrounded by the likes of Genesis Minerals (ASX:GMD), Saturn Metals (ASX:STN), Azure Minerals and KIN Mining (ASX:KIN). The Company notes the increase in M&A activity around the Leonora-Kookynie area and undertook a review of the project, including soil geochemical and ground magnetic data collected during a series of WMG field campaigns (ASX, Major Field Program Commences at Melita, 11 August 2021; Completion of Initial Field Program at Melita, 16 September 2021). During 2024 the Company completed a number of field visits to the Melita Project. A high resolution ground gravity survey was completed over the Airstrip Gossan area, along with geological mapping and sampling. A number of additional outcrops of Cu-Pb-Zn gossans were identified and sampled. At the Princess Melita area additional geological mapping of historical workings, sampling and metal detecting was undertaken. The results of this fieldwork are being interpreted and will be used to plan further work. During the period the Company compulsory surrendered 14 blocks from the project area as the tenement reached year seven, the core target areas of the project were maintained. Figure 10: Technical Director Dr Ben Grguric examining historical gold workings at the Melita Project ASX:WMG www.westernmines.com.au 14 ASX RELEASE | QUARTERLY ACTIVITIES REPORT MARCH 2025 PINYALLING The Pinyalling Project comprises exploration licence E59/2486 covering 55km2. The project is located approximately 25km NW of Paynes Finds and lies at the south-eastern end of the Yalgoo-Singleton Greenstone Belt, within an area known as the Warriedar Fold Belt that comprises a folded sequence of gabbro and dolerite intercalated with basalt, ultramafics, sediments and BIF. The Warriedar Fold Belt hosts a number of historic gold workings at the Pinyalling Mining Centre, 3km north of the tenement area, as well as the Baron Rothschild prospect drilled by Thundelarra Exploration during the 1990s. The Company engaged remote sensing specialists Earthscan Pty Ltd to complete satellite based remote sensing work over the project area, using ASTER multispectral imagery. This work was principally focused on mapping pegmatite sequences that could potentially host lithium mineralisation. A number of sub-cropping and outcropping pegmatites were subsequently encountered and sampled. The tenement area was found to contain a lot more remnant greenstone belt lithologies than the granitic terrane shown on GSWA geological mapping. These possible extensions of the nearby Warriedar Fold Belt increase the gold potential of the project area than first thought. A soil sampling survey to test the gold potential of the project area is being planned. PAVAROTTI The Pavarotti Project comprises exploration licence E77/2478 and exploration licence application E77/2746. The project is located approximately 50km north-northeast of Southern Cross and lies on the western side of the Koolyanobbing Greenstone Belt, a northwest trending sequence of mafic and ultramafic volcanic and intrusive rocks with lesser sediments intercalated with BIF horizons forming prominent ridges. The BIF horizons have been exploited since the 1960s, with several open pit iron ore mines that are currently owned by Mineral Resources (ASX:MIN). No exploration work was done on the project during the quarter. The Company continues to wait on the grant of tenement application E77/2746, containing Jock’s Fury, in order to commence exploration.
