Highlights ASX:WCE ANNOUNCEMENT 16 February 2026 WEST COAST SILVER LIMITED ASX | WCE Page 2 Role and Technical Focus Mr Smolonogov will lead technical eƯorts aimed at: • Applying advanced structural interpretation to identify high grade shoots • Enhancing drill targeting eƯiciency and success • Driving systematic step out and depth extension drilling • Integrating historical and modern datasets into updated geological models • Supporting the transition from exploration into resource definition and development This appointment also aligns with the Company’s objective of unlocking district scale silver potential across the Elizabeth Hill–Munni Munni corridor. Executive Director Bruce Garlick commented: “Serge’s appointment significantly strengthens our technical capability at a critical stage of growth for West Coast Silver. Recent drilling has returned exceptional results, including 27m at 1,314 g/t Ag (Diamond Hole 14)1, underscoring the high-grade and near-surface nature of mineralisation at Elizabeth Hill. Serge’s experience in advancing high-grade systems from discovery to development will be instrumental in accelerating resource growth and unlocking the broader district-scale potential.” Mr Smolonogov added: “Elizabeth Hill presents a compelling high-grade opportunity with clear scope for expansion along strike and at depth. I look forward to applying a systematic, structurally driven approach to further unlock value across the project and surrounding district.” About The Elizabeth Hill Project Elizabeth Hill is one of Australia’s historically highest-grade silver mines, having produced 1.2 Moz of silver from just 16,830 tonnes of ore at an average grade of 2,194 g/t Ag. Mining ceased in 2000 due to low silver prices (US$5/oz). The deposit remains open at depth, and the consolidated 180 km² land package hosts significant potential for additional Elizabeth Hill–style discoveries along the Munni Munni fault system. The project sits within a Tier-1 mining jurisdiction, with potential future processing optionality at the nearby Radio Hill facility (third-party owned, with no agreement currently in place This ASX announcement has been authorised for release by the Board of Directors of West Coast Silver Limited.
