Executive Director Bruce Garlick commented: The Board is highly encouraged by the outcomes of the recent shallow aircore scout drilling program at Elizabeth Hill near mine, along trend and regionally. The identification of multiple near-surface, high-grade silver intersections highlights Elizabeth Hill being an undervalued and underexplored property with confirmed growth opportunities through further exploration and development. The extension of high-grade mineralisation beyond the previously drilled area in 2025 is of considerable importance to value creation (refer ASX announcement 4th February 2026). The identification of high-grade silver in multiple shallow aircore holes to the north and northwest highlights potential for the mineralised system to extend significantly beyond current drilling. This clearly demonstrates that the Elizabeth Hill trend remains open for further exploration. The intersection of mineralisation within granite supports the prospectivity of further granite hosted mineralisation. This opens the prospectivity beyond one rock type hosting mineralization. The mineralized intersection at Elizabeth Hill South confirms historic silver intersections by previous explorers. Similarly, AC nickel and copper intersections at Natalie Hill support earlier historic drilling. The AC drilling in these areas opens-up Elizabeth Hill to being potentially just one part of a bigger mineralization story with opportunities for new silver and base metals occurrences regionally. 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 focussing on a disciplined program of developing the near surface and depth potential at Elizabeth Hill; extensions along strike; as well as testing the region for more high value silver targets. ASX:WCE ANNOUNCEMENT 24 February 2026 WEST COAST SILVER LIMITED ASX | WCE Page 3 DRILLING RESULTS Elizabeth Hill North The entire aircore hole 25WAC001 was mineralised with 24m @ 28g/t Ag from 2m (note that 0-2m was not sampled, as the hole was collared on a pad made from historical mine material). The hole is collared 10m west of 25WCDD019 (22m @ 578g/t Ag from 6m), opening a structural corridor to the north-northwest, entirely hosted in granite, and potentially related to a splay or flexure in the Munni Munni Fault (Figures 1, 2 and 6; Table 1). 25WCDD005 intersected 3m @ 787g/t Ag from 1m including 1m @ 2,340g/t Ag from 1m (note that 0-1m was excluded due to possible surface contamination) reflecting the tenor of mineralisation continuing to the north. Mineralisation in this interval is hosted in strongly oxidised and chlorite altered granite containing disseminated fine-grained sulphides (1-2m) and quartz veins (Figures 1, 2 and 8). Drill hole 25WCDD025 intersected 5m @ 55g/t Ag from 1m and contained gossan-like material from 5m to the end of hole at 8m (Figures 1, 2 and 8; Table 1). The gossan-like material contained 3m @ 1,492ppm Pb and 3m @ 344ppm Zn from 5m. Anomalous Pb and Zn are known to be associated with, and adjacent to, silver mineralisation at the Elizabeth Hill Silver Mine. Drill hole 25WCDD026 intersected 4m @ 88g/t Ag from surface in weathered and chlorite-altered granite hosting quartz-carbonate veins (<1mm thick) and increasing silicification at the bottom of hole from 3.5-4m (Figures 1, 2 and 9; Table 1). The silver intersection is supported by 1m @ 1,635ppm Co from surface which is known to be associated with high-grade silver mineralisation at the Elizabth Hill Silver Mine. Silver intersections in drill holes 25WCAC025 (Figure 8) and 25WCAC026 are 20m apart, demonstrating the continuity of the mineralisation corridor north of the Elizabeth Hill Silver Mine. Mineralisation intersected in 25WCAC008 (0.5m @ 61g/t Ag from 8m), located 225m north of the Elizabeth Hill mine on the northern extension of the Munni Munni Fault (Figures 1, 2 and 11; Table 1), is important for demonstrating the potential to the north of the historical workings. Elizabeth Hill South In addition, the intersection of 2m @ 39g/t Ag from 12m in 25WCAC071 is encouraging for the potential of the Elizabeth Hill prospect (Figures 1, 3 and 13; Table 1), 275m to the south of Elizabeth Hill where historical mineralisation such as 2m @ 1,550g/t Ag from 108m in drill hole AMEHRC012 and 1m @ 250g/t Ag from 118m in drill hole AG43 point to the potential of this underexplored area. Natalie Hill North Drill holes 25WCAC057 and 25WCAC058 aimed to test the northern ultramafic rock/granite contact (Figure 1) and a geochemical silver anomaly at this contact. However, the drill holes did not intersect the contact due to challenging ground conditions. Further exploration with RC drill holes is required to test this contact and geochemical anomaly. Natalie Hill South Drill holes 25WCAC059 to 25WCAC062 targeted the eastern contact of ultramafic rock of the Munni Munni intrusive complex and granite to the east (Figures 1 and 4). Drill hole 25WCAC059 intersected chlorite altered pyroxenite and granite, and 25WCAC060 to 25WCAC062 remained in chlorite altered pyroxenite. Drill hole 25WCAC060 contained 1m @ 2,480ppm Ni, 2,010ppm Cu and 107ppm Co from 11m related to fine-grained sulphide mineralisation. ASX:WCE ANNOUNCEMENT 24 February 2026 WEST COAST SILVER LIMITED ASX | WCE Page 4 Drill holes 25WCAC063 to 25WCAC065 tested a historical electromagnetic conductive anomaly (refer to East Coast Mineral N.L. ASX Announcement dated 30 April 2004) in chlorite altered pyroxenite with fine-grained sulphides associated with historically recognised platinum group element and base metal mineralisation in J Reef (refer to Alien Metals Ltd ASX Announcement dated 26 April 2023). Drill hole 25WCAC065 intersected 16m @ 1,888ppm Ni, 1,203ppm Cu and 127ppm Co from 4m. Drill hole 25WCAC066 tested outcropping carbonate veins within pyroxenite and intersected 24m @ 1,584ppm Ni, 1,001ppm Cu and 115ppm Co from surface associated with fine-grained, disseminated sulphides in pyroxenite. The sulphides intersected are consistent with previous reports of disseminated sulphide within the basal portion of the Munni Munni Complex intrusive stratigraphy in the area (refer to Alien Metals Ltd ASX Announcement dated 26 April 2023). The Company is assessing if a potential link exists between these base metal occurrences and silver mineralisation at Elizabeth Hill, as well as other potential exploration prospects for further hydrothermal mineralisation. CONCLUSIONS AND DISCUSSION The drilling has confirmed extensive high-grade silver mineralisation from surface and immediately to the north of the historical mine workings in an area that has been sparsely explored. Mineralisation now extends 150m north of the 2025 WCE diamond drilling and supports West Coast’s interpretation that mineralisation continues to the north, regardless of whether the host rock is ultramafic or granite, and the Munni Munni Fault remains an important controlling feature (Figure 1). The impressive aircore results from the 2025 drilling program provide confidence to expand exploration eƯorts at Elizabeth Hill North and Elizabeth Hill South, north and south of the historically mined area, respectively. The results extend the surface expression of high-grade silver mineralisation north of the mineralised envelope defined by the 2025 diamond drilling program (West Coast Silver ASX Announcement dated 4 February 2026). The intersection in 25WCAC071 at Elizabeth Hill South is consistent with previous deeper silver intersections in historical drilling and opens areas for further exploration of the granite-ultramafic contact on the Munni Munni Fault in that location. In addition, encouraging base metal sulphide intersections on the eastern side of the Munni Munni Complex at Natalie Hill to Natalie Hill South, oƯer encouragement for further exploration to investigate any link between such mineralisation and a broader hydrothermal mineralised system (including Elizabeth Hill) within the Project area. Relevant cross sections are in Appendix 1.

Planning of follow-up drilling, subject to results and approvals, targeting near-surface and near-mine extensions of known mineralisation. • Further drilling targeting: - 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 studies of near surface mineralisation being undertaken to support ongoing evaluation of a development pathway. ASX:WCE ANNOUNCEMENT 24 February 2026 WEST COAST SILVER LIMITED ASX | WCE Page 11 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)0F 1 . • Previous mining operation ceased in 2000: because of low silver prices (US$5)1F 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 oƯers potential to discover more Elizabeth Hill style deposits. • Located within the world class West Pilbara mining jurisdiction and having a mining lease with a potential processing option at the nearby Radio Hill site. Radio Hill is a third party-owned processing facility and WCE has signed an MOU with Artemis Resources Ltd to evaluate its suitability to potentially treat material from the Elizabeth Hill silver Mine. 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 24 February 2026 WEST COAST SILVER LIMITED ASX | WCE Page 13 APPENDIX 1: CROSS SECTIONS Aircore Drill Hole 25WCAC001 and Diamond Drill Holes 25WCDD019 and 25WCDD021 The entire aircore hole 25WCAC001 was mineralised with 24m @ 28g/t Ag from 2m (note that 0-2m was not sampled, as the hole was collared on a pad made from historical mine material). The hole is collared 10m west of 25WCDD019, opens a structural corridor to the west-northwest, which is entirely hosted in granite and may be related to a splay or flexure in the Munni Munni Fault (Figures 1, 2 and 6). Drill hole 25WCDD019 was designed to twin historical reverse circulation percussion (RC) drill hole EC079, intersecting silver mineralisation hosted within carbonate veins and iron-oxide rich veinlets, with associated malachite and black sulphide minerals, as previously reported (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 (WCE ASX Announcement dated 4 February 2026). The mineralised intersection in 25WCDD019 in the Munni Munni Fault and hangingwall, validates the silver mineralisation in EC079, and extends it 8m deeper than in EC079. The results indicate mineralisation is 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 5). 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 (WCE ASX Announcement dated 4 February 2026). Figure 6: Cross section A-A’ - 2025 drill holes 25WCAC001, 25WCDD019 and 25WCDD021 and historical drilling assay results. Note that 25WCAC001 was not sampled from 0m to 2m due to surface contamination. ASX:WCE ANNOUNCEMENT 24 February 2026 WEST COAST SILVER LIMITED ASX | WCE Page 14 Aircore Drill Holes 25WCAC002 and 25WCAC003 Drill hole 25WCAC002 intersected 3m @ 14g/t Ag from 2m and 12m @ 21g/t Ag from 12m (note that 0-1m sample was not included in the intersection due to possible contamination from surface material) in highly altered ultramafic rock with gossan like material (0m to 4m), and highly altered granite and gneiss with quartz-carbonate veins (<5mm thick) from 4m to the bottom of hole at 24m (Figures 1, 2 and 7). Drill hole 25WCAC003 intersected 2.5m @ 80g/t Ag from 1m (note that 0-1m sample was not included in the intersection due to possible contamination from surface material) in chlorite altered granite hosting quartz veins (<5mm thick). The granite is intensely silicified from 3m to the bottom of hole at 3.5m (Figures 1, 2 and 7). Figure 7: Cross section B-B’ with assay results for aircore holes 25WCAC002 and 25WCAC003 and historical holes ASX:WCE ANNOUNCEMENT 24 February 2026 WEST COAST SILVER LIMITED ASX | WCE Page 15 Aircore Drill Holes 25WCAC004, 25WCAC005 and 25WCAC025 Drill hole 25WCDD005 intersected 3m @ 787g/t Ag from 1m including 1m @ 2,340g/t Ag from 1m (note that 0- 1m was excluded due to possible surface contamination). Mineralisation in this interval is hosted in strongly oxidised and chlorite altered granite containing disseminated fine-grained sulphides (1-2m) and thin (<1mm) quartz veins (2-3m) (Figures 1, 2 and 8). Drill hole 25WCDD025 intersected 5m @ 55g/t Ag from 1m and contained gossan-like material from 5m to the end of hole at 8m (note that 0-1m was excluded due to possible surface contamination). The gossan-like material contained 3m @ 1,492ppm Pb and 3m @ 344ppm Zn from 5m. Anomalous Pb and Zn are known to be associated with, and adjacent to, silver mineralisation at the Elizabeth Hill Silver Mine (Figures 1, 2 and 8). Figure 8: Cross section C-C’ with assay results for aircore holes 25WCAC004, 25WCAC005, 25WCAC025 and historical holes ASX:WCE ANNOUNCEMENT 24 February 2026 WEST COAST SILVER LIMITED ASX | WCE Page 16 Aircore Drill Holes 25WCAC006 and 25WCAC026 Drill hole 25WCAC026 intersected 4m @ 88g/t Ag from surface in weathered and chlorite-altered granite hosting quartz-carbonate veins (<1mm thick), and increasing silicification in the bottom of hole from 3.5-4m (Figures 1, 2 and 9). The silver intersection is supported by 1m @ 1,635ppm Co from surface which is known to be associated with high-grade silver mineralisation at the Elizabth Hill Silver Mine. Silver intersections in drill holes 25WCAC025 (Figure 8) and 25WCAC026 are 20m apart, demonstrating the continuity of the mineralisation corridor north of the Elizabeth Hill Silver Mine. Drill hole 25WCAC006 intersected 1m @ 26g/t Ag from1m (note the 0-1m sample was excluded due to possible surface contamination) in moderately chlorite altered granite (Figures 1, 2 and 9). Figure 9: Cross section D-D’ with assay results for aircore holes 25WCAC006 and 25WCAC026 ASX:WCE ANNOUNCEMENT 24 February 2026 WEST COAST SILVER LIMITED ASX | WCE Page 17 Aircore Drill Holes 25WCAC017 to 25WCAC022 Very low-grade silver mineralisation above 5g/t Ag indicates slight silver enrichment distal to silver mineralisation (Figures 1, 2 and 10).

Figure 11: Cross section F-F’ with assay results for aircore holes 25WCAC007 to 25WCAC013 ASX:WCE ANNOUNCEMENT 24 February 2026 WEST COAST SILVER LIMITED ASX | WCE Page 19 Aircore Drill Holes 25WCAC027 to 25WCAC029 Drill holes 25WCAC027 to 25WCAC029 did not contain significant intersections above 10g/t Ag. Very low -grade silver, above 5g/t Ag, in drill hole 25WCAC027 is interpreted to reflect slight silver enrichment distal to silver mineralisation (Figures 1, 3 and 12).

Drill holes 25WCAC037 to 25WCAC039, and 25WCAC072 contained less than 5g/t Ag.
