West Coast Silver Accelerates Phase 2 Drilling at Elizabeth Hill

Phase 2 Drilling Underway

West Coast Silver Limited (ASX, WCE) has initiated the second phase of diamond drilling at its Elizabeth Hill Silver Project in the Pilbara region of Western Australia. The drilling program, which began on 11 October 2025, follows encouraging bonanza-grade intercepts from the initial Phase 1 campaign conducted between August and September this year.

The Phase 2 program aims to build on these early successes by focusing on two key objectives, confirming the continuity of very high-grade silver mineralisation near the surface, particularly adjacent to historical workings, and testing for potential deeper mineralised zones below the existing mine footprint. The company has planned approximately 14 diamond drill holes totaling around 1,300 metres, with scope to expand depending on the outcomes.

Strategic Use of Geophysics

Complementing the drilling, West Coast Silver has completed transient electromagnetic (TEM) and drone magnetic surveys across the project area. These geophysical datasets are currently being processed and are expected to refine drill targets along the significant Munni Munni Fault and associated parallel structures. The results will also inform an upcoming aircore drilling program scheduled for November.

Executive Chairman Bruce Garlick highlighted the dual focus of the campaign, "Phase 2 is designed to demonstrate near-surface continuity in the oxide zone and test a high-conviction deeper target that could represent a down-plunge repeat of the Elizabeth Hill system." This approach underscores the company's confidence in both shallow and deeper mineralisation potential.

Historical Context and Exploration Upside

Elizabeth Hill is a historically significant silver project, having produced approximately 1.2 million ounces of silver from just 16,830 tonnes of ore at an exceptional head grade of 2,194 grams per tonne. Mining ceased in 2000 due to low silver prices at the time, but the project remains highly prospective with the deposit open at depth.

Historical underground drilling has revealed spectacular silver grades, including intervals exceeding 1,900 grams per tonne, and evidence of native silver mineralisation. Additionally, intersections of massive nickel sulphides in nearby drill holes suggest complex geology that could host further valuable mineralisation. The project’s location within a tier 1 mining jurisdiction and proximity to processing infrastructure at Radio Hill add to its appeal.

Joint Venture and Regional Potential

The Elizabeth Hill Project is operated as a 70/30 joint venture between West Coast Silver and UK-listed Alien Metals (AIM, UFO). The consolidation of surrounding land parcels into a contiguous 180 square kilometre package provides a strategic advantage, covering significant portions of the Munni Munni fault system and related structures considered prospective for additional silver deposits.

With Phase 2 drilling now underway, the company is poised to refine its understanding of the deposit’s geometry and potentially expand the resource base. The integration of geophysical data and historical records will be critical in targeting the next generation of high-grade silver mineralisation at Elizabeth Hill.
