• Aim to unlock silver resource value and transition Elizabeth Hill to near-term, high-margin operation with phased growth
• Exceptional grade, low tonnage, 130m deep open pit key to a low capex, rapid payback pathway to position Elizabeth Hill for early cashflow generation
• Open mineralisation - at depth, laterally and along strike, with +6,000m RC and diamond drilling in progress to expand the mineral resource

West Coast Silver Limited ('WCE' or the 'Company') is pleased to outline its Growth & Development Plan for the Elizabeth Hill Silver Project, following the release of its inaugural Mineral Resource and recent high-grade drilling results. The Plan establishes a clear pathway to near-term production and scalable resource growth, positioning Elizabeth Hill as one of the highest-grade for lowest capital cost undeveloped silver projects globally. The maiden, JORC 2012 compliant Elizabeth Hill April 2026 Mineral Resource Estimate of 141kt @ 617g/t Ag for 2.8Moz establishes a compact, high-margin inventory with strong economic characteristics, including low tonnage, exceptional grades, simple metallurgy, and an open pit mining option for rapid development and maximum mined Ag ounce potential. WCE's development strategy is focused on rapid de-risking and progression toward production, leveraging the Project's unique advantages such as a Granted Mining Lease, historic mine infrastructure, and proximity to processing infrastructure. The Company's 2026 drilling program is designed to materially expand the resource footprint, extend mineralisation below and to the south of historical mine workings, and test for new mineralisation 'pearls' along the Munni Munni Fault. Elizabeth Hill's unique grade profile, with the ability to mine low cut-off grades down to >20 g/t Ag and spatially distinct high-grade zones at >1,000 g/t Ag, supports a rapid payback, high-return development scenario, distinguishing it from typical polymetallic silver projects.

The Company has outlined a development pathway based on a staged program of drilling, metallurgical work, resource updates and a scoping study, with the objective of assessing development options by early 2027.
