Highlights ASX:WCE ANNOUNCEMENT 5 November 2025 WEST COAST SILVER LIMITED ASX | WCE Page 2 West Coast Silver Limited (ASX: WCE) (“West Coast Silver” or the“Company”) is pleased to advise that the follow up diamond drill program to the inaugural diamond drilling at the high-grade historic Elizabeth Hill Silver Project in the Pilbara (Western Australia) has delivered an exceptional start, with shallow visual native silver and related silver-bearing minerals confirmed in four of the first five holes completed (Figure 8, Appendix 1). Commenting on the results, Executive Chairman Bruce Garlick said: “We are extremely pleased with this exceptional start to our follow up drill program. To intersect Native silver in two drill holes and silver-bearing minerals in another two holes close to surface is a tremendous result and validates our belief in the near-surface potential at Elizabeth Hill. DRILL HOLE MINERALISATION: VISUAL OBSERVATIONS/PXRF Throughout the drilling process, all drill holes undergo geological logging to assess lithology, alteration, and mineralisation. In four of the initial five completed drillholes, native silver and/or silver minerals were identified and verified using a Vanta portable XRF (“pXRF”) device. It is important to note that while pXRF readings provide valuable insights, they should not be considered a substitute for thorough laboratory analysis. These readings reflect elemental concentrations at specific locations rather than providing a comprehensive overview of the entire rock sample. WCE emphasises that visual estimates of mineral abundance should not be regarded as a proxy or substitute for laboratory analyses, particularly when concentrations or grades are of primary economic significance. Furthermore, visual estimates do not yield information concerning impurities or detrimental physical properties that are pertinent to valuations. DESCRIPTION OF SILVER MINERALISATION Drill hole 25WCDD014 Diamond drill hole 25WCDD014 contained three intervals of native silver mineralisation identified by geological logging and confirmed by pXRF analysis (Appendix 2). The geologically logged intervals of native silver mineralisation occur within the following intervals of the core photos below: • 53.57m to 54.07m - 1% to 2% observed native silver (Figure 2). • 66.24m to 66.42m - 1% observed native silver (Figure 3). • 74.52m to 74.95m - 1% observed native silver (Figure 4).

Figure 9. Cross section with historical drilling and recently completed drill holes. Diamond drill hole 25WCDD014 terminated at the top of historical underground workings ASX:WCE ANNOUNCEMENT 5 November 2025 WEST COAST SILVER LIMITED ASX | WCE Page 10 Drill hole 25WCDD016 This drill hole was targeting the prospective interaction of the Munni Munni fault and granite/ultramafic contact in the northern up plunge position representing the oxide component of the deeper, native silver and silver sulphide mineralisation (Figure 10). Figure 10. Cross section with historical drilling and recently completed drill hole 25WCDD016 ASX:WCE ANNOUNCEMENT 5 November 2025 WEST COAST SILVER LIMITED ASX | WCE Page 11 Drill hole 25WCDD017 This drill hole was targeted to intersect the prospective ultramafic rock and granite contact as well as the Munni Munni fault above the historical underground workings (Figure 11). Drill hole 25WCDD017 was designed to twin historical reverse circulation percussion drill hole EC100 and verify its reported mineralisation (EC100: 14m @ 404g/t Ag from 28m; refer to ASX Announcement dated 16th July 2025). Figure 11. Cross section with historical drilling and recently completed drill hole 25WCDD017 ASX:WCE ANNOUNCEMENT 5 November 2025 WEST COAST SILVER LIMITED ASX | WCE Page 12 Drill hole 25WCDD015 Drill hole 25WCDD015 intersected the Munni Munni fault and the contact between ultramafic rock and granite (Figure 12). Although no visible silver mineralisation was observed during geological logging anomalous Ag and Pb was reported in spot pXRF analyses in the down hole interval 51.18m to 59.36m. The location of this interval is consistent with mineralisation reported in nearby historic drill holes(Figure 12). The subsequent assaying of the core from this drill hole will determine the presence and extent of any silver or any associated mineralisation within this zone. Figure 12. Cross section with historical drilling and recently completed drill hole 25WCDD015 Laboratory Testing Core from the first three holes has been cut, and half-core has been sampled and dispatched for laboratory analysis. Core cutting and sampling activities are continuing, with analytical results expected mid-December 2025 to early January 2026 (indicative). Ongoing drilling, sampling and submission will vary depending on drilling progress. Result timeframes may vary pending on laboratory analysis requirements for further analysis of any over-grade silver mineralisation. Selected samples have been submitted for expediated laboratory processing. ASX:WCE ANNOUNCEMENT 5 November 2025 WEST COAST SILVER LIMITED ASX | WCE Page 13 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)2 . • Previous mining operation ceased in 2000: because of low silver prices (US$5)3 . • 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. • 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.” Figure 13. Tenement Location 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. 2 WAMEX Annual Report,1 April 2014 to 31 March 2015, Elizabeth Hill Silver Project, Global Strategic Metals NL, p16 3 www.kitco.com/charts/silver ASX:WCE ANNOUNCEMENT 5 November 2025 WEST COAST SILVER LIMITED ASX | WCE Page 14 This ASX announcement has been authorised for release by the Board of Directors of West Coast Silver Limited.
