• Inaugural Mineral Resource Estimate of 2.8 Moz Silver from 141,000t at 617g/t Ag
• Establishes Elizabeth Hill as one of Australia's highest-grade silver deposits
• Optimised open pit captures almost all current mineralisation, including historical underground areas

West Coast Silver Limited (ASX: WCE) is pleased to announce the results of the inaugural Mineral Resource estimate (MRE) at the Elizabeth Hill Silver Project in Western Australia. The MRE establishes a robust, high-grade foundation that will support continued development throughout 2026, paving the way for additional economic studies. The MRE includes 2.8 Moz Silver from 141,000t at 617g/t Ag, including 369,000 oz Indicated and 2.42 Moz Inferred, reported above a 20 g/t Ag cut-off. This confirms Elizabeth Hill as one of Australia's highest-grade silver deposits. The pit optimisation extends to the limits of most drilling and includes historical areas mined from underground, demonstrating the robustness of the deposit and the growth opportunities remaining at depth, along strike, and peripheral to existing mineralisation. As 40% of MRE tonnes and 86% of silver ounces remain in the Inferred category, there is opportunity to significantly grow the MRE by further drilling within the open pit optimisation to convert Inferred resources to Indicated resource status.

The consensus metal prices used to define the open pit optimisation capture almost the entirety of the current mineralisation, including mining around the previous Elizabeth Hill underground operation.

Mineralisation remains open along strike and at depth, with significant upside from near-mine and regional targets. The MRE represents a foundation inventory, with clear potential for growth through ongoing drilling and geophysics across a ~180 km² land package.
