Quarter Overview The Company’s focus during the Quarter was resource growth and development readiness at Elizabeth Hill. Activities included completion of the H1 2026 diamond drilling program and receipt of all outstanding assays, final assays from the Elizabeth Hill North RC program, grant of the Elizabeth Hill West tenement, design of the H2 2026 diamond drilling program and preparation of the regional IP and CSAMT geophysics program. The Company also completed a Board restructure, leadership transition, and raised $6.0 million to fund the next phase of work. West Coast Silver holds a 70% interest in the historical Elizabeth Hill Silver Project and associated interests within the broader approximately 180 km² project area in the Pilbara region of Western Australia. The consolidated tenure covers a substantial portion of the Munni Munni Fault corridor, which is considered prospective for additional Elizabeth Hill-style silver mineralisation. CEO Commentary Commenting on the Quarter, Chief Executive Officer Sergei Smolonogov said: “This was a quarter of delivery at Elizabeth Hill. Diamond drilling returned 38.3m @ 878g/t Ag from just 3.7m downhole within the resource area, and broad near-surface intercepts such as 63.0m @ 53g/t Ag from 2.0m which extended mineralisation west into granite, outside the current resource. Together with the new high-grade zone identified below the historical workings, these results give us clear targets for resource growth. The oversubscribed $6 million placement funds the next stage of exploration and resource development. Our H2 diamond drilling program targets resource conversion, western mineralisation extensions, new Deeps zone mineralisation, and a regional IP and CSAMT survey that has commenced across approximately 4km of the Munni Munni Fault Zone in search of repeats of Elizabeth Hill. Our priorities are clear - an updated Mineral Resource Estimate in November, a further resource update in March 2027 and Scoping Study outcomes towards the end of the first quarter of 2027.” • H1 2026 diamond drilling completed with 14 holes for 2,015.7m, testing deeper targets beneath the mine, extensions north and west of the MRE and infill within the MRE block model. • H1 2026 reverse circulation (“RC”) drilling completed for 2,710m from 32 holes across the Elizabeth Hill North (EHN) program. • All outstanding assays from H1 diamond and RC drill programs were received and reported. • Prospecting Licence P47/2033 covering the mineralised Elizabeth Hill West Prospect was granted. • H2 2026 diamond drilling and regional IP and CSAMT geophysics programs were finalised for Q4 2026. Elizabeth Hill Silver Project Highlights ASX: WCE ANNOUNCEMENT 15 October 2026 3 ASX | WCE WEST COAST SILVER LIMITED westcoastsilver.com.au Diamond Drilling Results Assays were received during the Quarter for the remaining holes of the H1 2026 diamond drilling program, which was completed in July 2026 with 14 holes for 2,015.7m.2 The program tested deeper targets beneath the mine, followed up RC results north and west of the April 2026 MRE3 and infilled the MRE block model. All intervals reported below are downhole lengths, not true widths. MRE Infill and Western Extension Drilling (26WCDD037 to 26WCDD039) Holes 26WCDD037 to 26WCDD039 (Figure 1 and 2) were drilled from west to east to infill near-surface Inferred and Indicated MRE categories and test for extensions beyond the MRE’s western limit4 . All three holes intersected mineralisation beyond the western limit of the current MRE block model and into granite. High-grade intervals in 26WCDD037 contained visible native silver (Figure 2, Figure 3). Significant intersections include: • 38.3m @ 878g/t Ag from 3.7m (26WCDD037), including – o 22.3m @ 1,495g/t Ag from 19.7m (including 1.4m @ 23,360g/t Ag from 29.0m); and o 13.5m @ 2,253g/t Ag from 45.0m (including 9.1m @ 3,318g/t Ag from 47.85m). • 63.0m @ 53g/t Ag from 2.0m (26WCDD038), including 31.3m @ 92g/t Ag from 26.7m. • 20.15m @ 53g/t Ag from 15.0m (26WCDD039), including 14.8m @ 61g/t Ag from 16.2m. The results are expected to inform the updated MRE through potential additions to mineralised volume and changes to estimated silver grades within and outside the current MRE. The extent of any change will not be known until that estimate is completed. Any reference to potential additions to the Mineral Resource is conceptual in nature. There has been insufficient exploration in these areas to estimate a Mineral Resource and it is uncertain whether further exploration will result in the estimation of a Mineral Resource. 2 Refer WCE ASX Announcement "Completion of Diamond Drilling at Elizabeth Hill Project" dated 30 July 2026. 3 Refer WCE ASX Announcement "Elizabeth Hill - 2.8Moz Silver Mineral Resource Estimate" dated 22 April 2026. 4 Refer WCE ASX Announcements "Bonanza Silver Grades & Growth of Elizabeth Hill Project” and "Correction - Bonanza Silver Grades at Elizabeth Hill", both dated 27 August 2026.

ASX: WCE ANNOUNCEMENT 15 October 2026 15 ASX | WCE WEST COAST SILVER LIMITED westcoastsilver.com.au About the Elizabeth Hill Project Elizabeth Hill is one of Australia’s high-grade silver projects (Figure 9) 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)12 . • Previous mining operation ceased in 2000: because of low silver prices (US$5/oz)13 • Simple 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. Figure 9. Elizabeth Hill Project Tenement Location Through the consolidation of the surrounding land packages into a single contiguous 180 km2 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 which is considered prospective for Elizabeth Hill style silver deposits. 12 WAMEX Annual Report,1 April 2014 to 31 March 2015, Elizabeth Hill Silver Project, Global Strategic Metals NL, p16. 13 www.kitco.com/charts/silver ASX: WCE ANNOUNCEMENT 15 October 2026 16 ASX | WCE WEST COAST SILVER LIMITED westcoastsilver.com.au • No field activities were undertaken by the Company on its other exploration projects during the Quarter. Farm-in partner Falcon Metals commenced drilling at the Errabiddy Gold Project, as outlined below. • Falcon Metals Limited (ASX: FAL) (“Falcon”) received all regulatory and heritage approvals and commenced maiden RC drilling at the Olsen Well gold target on E09/2457 during the Quarter. Falcon plans approximately 50 RC holes for 6,000m, increased from a previously announced 3,500m program. Drilling is funded by Falcon as part of its earn-in obligations, at no cost to the Company.14 The Errabiddy project comprises three tenements with a combined area of approximately 545 km2 and which are considered prospective for Ni, Cu, Au, REE’s, Li and graphite. The results from routine reconnaissance prospecting, soil sampling and rock chip sampling which was previously undertaken on the project by West Coast Silver have resulted in an initial focus on graphite and gold. Falcon Metals Joint Venture Previously, West Coast Silver entered an Earn-in, Joint Venture and Mineral Rights Agreement with Falcon Metals Ltd (ASX: FAL) (“Falcon”), granting Falcon the right to earn up to a 70% interest in Exploration Licence E09/2457 by spending $2 million in two stages over a 60-month period, covering all minerals excluding graphite. The Errabiddy Gold Project is a craton margin gold target, located 220 km northwest of Meekatharra in Western Australia. The 519 km2 JV licence covers a 42 km strike extent of the Errabiddy Shear Zone, which is considered highly prospective, remains underexplored and with no previous drilling for gold conducted within the project tenure. The Errabiddy Shear Zone is a compelling cratonic margin gold target which contains known gold mineralisation. Cratonic margins are considered prospective for the formation of large gold deposits, including the Tropicana deposit that was discovered on the eastern margin of the Yilgarn Craton in 2005 through the follow up of a regional public domain gold-in-soil anomaly. West Coast Silver initially identified Olsen Well as a target from a review of public domain Bulk Leach Extractable Gold (“BLEG”) stream sediment data that highlighted this area. Additionally, regional geochemical sampling by the Geological Survey of Western Australia, with a 4 km spaced geochemical grid, detected a 6ppb Au anomaly near Olsen Well. The sampling undertaken by West Coast Silver in 2023 revealed the Olsen Well Prospect to be a significant gold in soil anomaly with a surface extent of at least 3 km x 1 km with a peak soil value of 234 ppb Au. The soil sampling grid was 300 m x 100 m with 462 samples collected, and the anomaly coincident with quartz and iron rich rocks hosted within a granitic terrain. This anomalous gold in soil footprint was expanded to a strike of 5.8 km by subsequent soil sampling by JV partner Falcon Metals. The Olsen Well gold target is considered by Falcon Metals 14 Refer WCE ASX Announcement "Falcon, Farm-in Partner, Secures Approval to Drill Errabiddy" dated 28 July 2026 and Falcon Metals Limited ASX Announcement "Maiden Drilling Underway at Errabiddy Gold Project" dated 15 September 2026.
