Highlights ASX:WCE ANNOUNCEMENT 4 February 2026 WEST COAST SILVER LIMITED ASX | WCE Page 2 Photo 1: Photograph of sectioned and preserved half HQ3 drill core (25WCDD014) at 75.05m to 75.15m. This drill core shows 2mm to 4mm grains of native silver hosted within and adjacent to 5cm thick carbonate vein in an ultramafic host rock. West Coast Silver Limited (ASX: WCE) (‘West Coast Silver’ or the ‘Company’) is pleased to advise assay results for diamond drill program (13 holes for 1,015.25m: 25WCDD013-025) have been received from the Phase 2 diamond drilling program at the Elizabeth Hill Joint Venture Project (WCE 70%, Alien Metals 30%) (‘Elizabeth Hill’) near Karratha, Pilbara region of Western Australia (Figure 1, Figure 3). Executive Director Bruce Garlick commented: The Board is very encouraged by the results delivered from this Phase 2 drilling program at Elizabeth Hill. The confirmation of multiple near-surface and bonanza-grade silver intersections reinforces Elizabeth Hill’s standing as one of Australia’s highest-grade silver projects. Of particular significance is the extension of high-grade mineralisation beyond the previously drilled footprint. High-grade silver intersected in drill hole 25WCDD019 further toward the northwest highlights the potential for the mineralised system to extend well beyond existing drilling, clearly indicating that the Elizabeth Hill trend remains open. In addition, the intersection of long intervals of mineralisation in 25WCDD019 (22.0m @ 578g/t Ag) and 25WCDD020 (24.8m @ 151g/t Au), predominately intersected in the hanging wall granite is highly important for further exploration as mineralisation of this magnitude has not previously recognised this far into the granite, opening up the likelihood of further granite hosted mineralisation. The latest drilling has increased confidence in the scale potential of the silver mineralised system at Elizabeth Hill. The Board looks forward to updating shareholders as the Company advances the Project through the next phase of exploration in 2026. ASX:WCE ANNOUNCEMENT 4 February 2026 WEST COAST SILVER LIMITED ASX | WCE Page 3 DRILLING RESULTS Nine of the 13 diamond drill holes intersected significant high-grade silver mineralisation. The highest- grade intersection was returned from drill hole 25WCDD014: • 27.4m @ 1,314g/t Ag (42 oz/t) from 49m, including multiple bonanza-grade intervals. Photo 1 demonstrates the distribution and form of silver mineralisation in drill hole 25WCDD014. Further intervals of native silver identified in 25WCDD014 drill core (Photos 2 to 4 and WCE ASX Announcement dated 5 November 2025). The significant high-grade silver intersections include: • 4.15m @ 3,677g/t Ag (118 oz/t) from 52.85m down hole including 0.4m @ 16,291g/t Ag (524 oz/t) from 53.70m and 0.9m @ 5,290g/t Ag (170 oz/t) from 54.10m. • 0.28m @ 5,660g/t Ag (182 oz/t) from 66.15m down hole. • 2.4m @ 7,288g/t Ag (234 oz/t) from 74.00m down hole including 0.35m @ 33,107g/t Ag (1,064 oz/t) from 74.6m and 0.25m @ 17,534g/t Ag (564 oz/t) from 74.95m. Drill hole 25WCDD014 intersected native silver in veins and stockworks and terminated in historical mine workings (Figure 1 and 2). The bonanza-grade results provide insight into the grades historically mined at Elizabeth Hill and indicate the presence of additional high-grade silver mineralisation beyond that previously interpreted from historical drilling. Drill hole 25WCDD019 intersected a broad zone of near-surface silver mineralisation: • 22.0m @ 578g/t Ag (19 oz/t) from 6m, including 0.9m @ 9,070g/t Ag (292 oz/t) This hole was drilled on the northernmost drill line and intersected mineralisation further west than previously tested, suggesting a change in strike of the Munni Munni fault and indicating that mineralisation remains open to the northwest. Drill hole 25WCDD022 intersected high-grade silver mineralisation, returning: • 1.95m @ 1,252g/t Ag (40 oz/t) from 54.6m, including 1.20m @ 1,894g/t Ag (61 oz/t) Mineralisation in 25WCDD022 was associated with sulphide-bearing carbonate veins in ultramafic rocks adjacent to historical stopes.

EXPLORATION IMPLICATIONS The drilling has confirmed extensive high-grade silver mineralisation close to surface and immediately above historical mine workings. The results support West Coast’s interpretation that the southerly plunge of silver mineralisation broadens as it flattens and approaches surface, creating additional near- surface targets for further exploration (Figure 2). High-grade silver intercepts in drill hole 25WCDD019 represent the most north-westerly mineralisation intersected to date. The change in the strike of mineralisation corresponds with an interpreted change in the direction of the Munni Munni fault, indicating the mineralised trend remains open to the northwest and may host additional high-grade silver mineralisation. The consistency of high-grade results validates historical drilling and provides confidence to expand exploration beyond the historically mined areas. NEXT STEPS Following the high-grade results intersected in the 2025 diamond drilling programs (Phase 1 and 2), the Company will progress exploration at Elizabeth Hill in a structured and disciplined manner. • Results from the 76-hole (1,060m) aircore drill program completed in November 2025. Pending results are expected in mid-February 2026. It is anticipated the results will further refine targets for near-surface silver mineralisation and prioritising follow-up RC and diamond drilling. • Detailed geological and structural review of all 2025 drilling data, including the interpreted change in strike and plunge of mineralisation, particularly the newly identified targets in the northwest of the Elizabeth Hill Project. Planning of follow-up drilling, subject to results and approvals, targeting near-surface and near-mine extensions of known mineralisation. • Further drilling planned targeting on: - extensions of high-grade mineralisation along strike and at depth. - near-mine targets adjacent to historical workings. - priority targets identified from aircore drilling and the new geological reinterpretation. • Surface and down-hole geophysical surveys to improve targeting and support drill planning during 2026. • JORC Mineral Resource Estimate and economic study of near surface mineralisation being undertaken to support ongoing evaluation of a development pathway. ASX:WCE ANNOUNCEMENT 4 February 2026 WEST COAST SILVER LIMITED ASX | WCE Page 8 About The Elizabeth Hill Project Elizabeth Hill is historically one of Australia’s highest grade silver projects and has a proven production history outlined below: • High grades enabled low processing tonnes: 1.2Moz of silver was produced from just 16,830t of ore at a head grade of 2,194g/t (70.5 oz/t Ag)1 . • Previous mining operation ceased in 2000: because of low silver prices (US$5)2 . • Simplistic historical processing technique: native silver was recovered via low-cost gravity separation techniques. • Untapped potential remains in ground with deposit open at depth and recent consolidation of land package offers potential to discover more Elizabeth Hill style deposits. • Tier 1 Mining Jurisdiction located on a mining lease with potential processing option at the nearby Radio Hill site. Radio Hill is a third party-owned processing facility; WCE has no current agreement in place. Through the consolidation of the surrounding land packages into a single contiguous 180km2 package significant exploration and growth potential exists both near mine and regionally. The land package holds a significant portion of the Munni Munni fault system, and other fault systems subparallel to the Munni Munni fault system, which are considered prospective for Elizabeth Hill look-a-like silver deposits.

ASX:WCE ANNOUNCEMENT 4 February 2026 WEST COAST SILVER LIMITED ASX | WCE Page 10 CROSS SECTIONS Drill Holes 25WCDD019 and 25WCDD021 Drill holes 25WCDD019 and 25WCDD021 were designed to test near surface mineralisation at the ultramafic- granite contact where it is intersected by the subvertical Munni Munni Fault (Figures 1, 2 and 4). Drill hole 25WCDD019 was designed to twin historical reverse circulation percussion (RC) drill hole EC079, intersected silver mineralisation hosted within carbonate veins and iron-oxide rich veinlets, with associated malachite and black sulphide minerals, as previously reported (refer to WCE ASX Announcement dated 5 November 2025). Assay results returned a significant intersection of 22m @ 578g/t Ag from 6m, including 0.9m @ 9,070g/t Ag from 9m. The wide intersection of silver mineralisation in 25WCDD019 within the Munni Munni Fault and its hangingwall validates the silver mineralisation in EC079 and extends it by another 8m down hole beyond the end of historical drilling. The results indicate that mineralisation remains open to the northwest along a flexure in the Munni Munni fault, with further drilling required to test this interpretation. Drill hole 25WCDD021 was designed to target mineralisation east and below historical RC hole EC080 (Figure 4). The significant intersections in the drill hole confirm the targeting criteria and include 3.2m @ 46g/t Ag from 8m, 5m @ 27g/t Ag from 16m and 7.52m @ 28g/t Ag from 28.48m. Figure 4: Cross section A-A’ - 2025 drill holes 25WCDD019 and 25WCDD021 and historical drilling assay results. The dip of mineralisation and sheeted vein/stockwork zone may be an apparent dip due to the Munni Munni fault flexing northwest. ASX:WCE ANNOUNCEMENT 4 February 2026 WEST COAST SILVER LIMITED ASX | WCE Page 11 Drill Holes 25WCDD016 and 25WCDD020 Drill holes 25WCDD016 and 25WCDD020 were designed to test the interaction of the Munni Munni fault and granite-ultramafic contact in the northern up-plunge position of the Elizabeth Hill mineralisation (Figures 1, 2 and 5). These drill intersections represent the oxidised expression of the deeper native silver and silver sulphide mineralisation. Drill hole 25WCDD020, drilled to twin historical RC drill hole EC072, intersecting both primary and secondary silver minerals associated with carbonate veins at shallow depth, with silver mineralisation and minor galena and sphalerite within a brecciated, quartz-veined zone. Assay results of 4m @ 36g/t Ag from 5m, 1m @ 28g/t Ag from 12m, 1.16m @ 26g/t Ag from 15.84m, and 25.8m @ 151g/t Ag from 20m broadly confirm historical results and extend mineralisation to greater depth and further west. Drill hole 25WCDD016 intersected low-grade silver mineralisation up to 21.9g/t Ag associated with iron oxide minerals in a carbonate matrix (Appendix 3) (WCE ASX Announcement dated 5 November 2025). The Company interprets the main silver mineralisation to plunge to the south, with 25WCDD016 intersecting below the interpreted plunging mineralised zone. Figure 5: Cross section B-B’ - 2025 drill holes 25WCDD016 and 25WCDD020 and historical drilling assay results ASX:WCE ANNOUNCEMENT 4 February 2026 WEST COAST SILVER LIMITED ASX | WCE Page 12 Drill Hole 25WCDD015 Drill hole 25WCDD015 was designed to test for down-plunge extensions of high-grade silver mineralisation along the Munni Munni fault (Figure1, 2 and 6). This drill hole intersected intensely silicified granite within the fault zone and at the ultramafic-granite contact withno significant silver mineralisation intersected. WCE interprets the silver mineralisation in the upper parts of the section plunges to the south, with 25WCDD015 intersected below the interpreted plunging mineralised zone. Figure 6: Cross section C-C’ - 2025 drill hole 25WCDD015 (NSI) and historical drilling assay results ASX:WCE ANNOUNCEMENT 4 February 2026 WEST COAST SILVER LIMITED ASX | WCE Page 13 Drill Holes 25WCDD013 and 25WCDD014 Drill holes 25WCDD013 and 25WCDD014 targeted the interaction of the Munni Munni fault and granite-ultramafic contact, and mineralisation at the upper portion of the Elizabeth Hill mine sequence (Figures 1, 2 and 7). Drill hole 25WCDD014 targeted extensions of mineralisation to the east and beneath historical RC drill hole EC097. Geological logging identified three intervals with native silver hosted within and adjacent to carbonate veins, as previously reported (WCE ASX Announcement dated 5 November 2025). These logging observations supported by assay results include: • 27.4m @ 1,314g/t Ag from 49m down hole. • including 4.15m @ 3,677g/t Ag from 52.85m. • included within 0.4m @ 16,291g/t Ag from 53.70m and 0.9m @ 5,290g/t Ag from 54.10m. • including 0.28m @ 5,660g/t Ag from 66.15m. • including 2.4m @ 7,288g/t Ag from 74.00m. • included within 0.35m @ 33,107g/t Ag from 74.6m and 0.25m @ 17,534g/t Ag from 74.95m. Drill hole 25WCDD013, drilled as a twin to historical RC drill holes EC094 and EC095, intersected oxidised carbonate-quartz veins and secondary minerals consistent with historical observations. Assay results of 15m @ 41g/t Ag from 11m down hole and 6m @ 37g/t Ag from 32.00m down hole confirm the historical drilling results. Figure 7: Cross section D-D’ - mineralisation outline and silver mineralisation in 25WCDD013 and 25WCDD014 ASX:WCE ANNOUNCEMENT 4 February 2026 WEST COAST SILVER LIMITED ASX | WCE Page 14 Drill Holes 25WCDD017 and 25WCDD018 Drill holes 25WCDD017 and 25WCDD018 were designed to test the ultramafic-granite contact and Munni Munni fault (Figures 1, 2 and 8). Drill hole 25WCDD017, drilled as a twin to historical RC drill hole EC100, intersected silver mineralisation including trace native silver, occurring as 1mm to 2mm grains at 43.61m within a quartz vein in a late fracture (refer to WCE ASX Announcement dated 5 November 2025). The drill hole intersected 3m @ 31g/t Ag from 26m down hole, and 15.75m @ 64g/t Ag from 34.25m down hole validating the historical results in EC100 (Figure 8). Drill hole 25WCDD018, drilled as twin to historical RC hole EC098, intersected silver mineralisation with galena and jarosite at 21.43m (refer to WCE ASX Announcement dated 5 November 2025) with significant intersections including 0.67m @ 45g/t Ag from 15.33m down hole, 2.69m @ 53g/t Ag from 20.31m down hole, and 1m @ 27g/t Ag from 27m down hole confirming the historical silver mineralisation intersected in EC098 (Figure 8). Figure 8: Cross section E-E’ - 2025 drill holes 25WCDD017 and 25WCDD018 and historical drilling assay results ASX:WCE ANNOUNCEMENT 4 February 2026 WEST COAST SILVER LIMITED ASX | WCE Page 15 Drill Holes 25WCDD022 and 25WCDD024 Drill holes 25WCDD022 and 25WCDD024 were designed to test the vertical ultramafic-granite contact and the Munni Munni fault at Elizabeth Hill (Figure 1, 2 and 9). Drill hole 25WCDD022 was targeted to twin historical RC drill hole EC105, intersected silver sulphide mineralisation at 54.95m, with silver mineralisation associated with sphalerite between 55.75m and 55.90m. Assay results returned multiple silver intersections including 1m @ 40g/t Ag from 42m down hole, 4.1m @ 91g/t Ag from 48m down hole and high-grade intersection of 1.95m @ 1,252g/t Ag from 54.60m down hole that includes 1.2m @ 1,894g/t Ag from 54.60m down hole. These results validate the historical silver intersection in EC105. Drill hole 25WCDD024 drilled as a twin of historical RC hole EC112. No visible silver mineralisation was identified during the logging; however, assay results returned a silver intersection of 1.2m @ 62g/t Ag from 27.8m down hole, confirming the historical intersection in RC hole EC112. Figure 9: Cross section F-F’ - 2025 drill holes 25WCDD022 and 25WCDD024 and historical drilling assay results ASX:WCE ANNOUNCEMENT 4 February 2026 WEST COAST SILVER LIMITED ASX | WCE Page 16 Drill Holes 25WCDD023 and 25WCDD025 Drill holes 25WCDD023 and 25WCDD025 were designed to test the ultramafic-granite contact and Munni Munni fault below and to the south of the historical underground workings (Figure 1, 2 and 10). Drill hole 25WCDD025 intersected an extensive sheeted and stockwork vein system and silicified alteration zone between 174.45m and 208.55m, returning lower grade silver mineralisation up to 15.7g/t Ag. Drill hole 25WCDD023 intersected sheeted quartz-carbonate between 195.00m and 202.00m, with silicified alteration of granite intersected between 204.00m and 217.00m. Low-grade silver mineralisation up 12.25g/t Ag was returned. The low-grade Ag mineralisation in 25WCDD023 and 25WCDD025 is consistent with the lower grade halo mine sequence peripheral to the high-grade intercept reported in historical diamond drill hole UGD84 (2m @ 1,995g/t Ag from 61m down hole).
