Elizabeth Hill Expansion Drilling Raises Stakes for West Coast Silver’s Next Phase

Drilling Commences to Expand High-Grade Silver Footprint

West Coast Silver Limited (ASX:WCE) has initiated an up to 4,000-metre Reverse Circulation (RC) drilling program at its flagship Elizabeth Hill silver project, located in the Pilbara region of Western Australia. This campaign aims to extend the known high-grade silver mineralisation along the Munni Munni Fault, a major structural feature controlling mineral deposits in the area.

The drilling focuses on near-surface targets within approximately 150 metres of the surface, which could be amenable to cost-effective open-pit mining. By targeting the northern and southern extensions of the Elizabeth Hill mineralised system, the company hopes to build on encouraging results from its 2025 drilling program, which revealed moderate to high-grade silver intersections close to surface.

Strategic Importance of the Munni Munni Fault

The Munni Munni Fault is a significant regional control on silver mineralisation at Elizabeth Hill. West Coast Silver’s current drilling is designed to test mineralisation continuity along this fault, including areas north and northwest of previous drilling sites known as Elizabeth Hill North and Elizabeth Hill South. The program also aims to extend the mineralised footprint up-dip and plunge of the historical underground mine, which ceased operations in 2000 due to low silver prices but produced exceptionally high grades during its life.

Executive Chairman Bruce Garlick highlighted the strategic nature of this drilling campaign, noting that the 2025 results confirmed the mineralisation extends beyond the historical mine boundaries. He emphasised that the shallow targets and proximity to existing infrastructure position Elizabeth Hill well for rapid advancement towards an Economic Scoping Study.

Broader Exploration and Development Plans

The RC drilling is part of a broader exploration push scheduled through to May 2026. Complementary activities include down-hole and surface geophysics starting late March, and diamond drilling planned for early April to test the down-plunge extensions of the orebody. These efforts will feed into West Coast Silver’s inaugural Mineral Resource Estimate for Elizabeth Hill, a critical milestone for project valuation and development planning.

Elizabeth Hill is notable for its world-leading silver grades, with historic mining yielding 1.2 million ounces of silver from just under 17,000 tonnes of ore at an extraordinary average grade exceeding 2,000 grams per tonne. The project’s consolidation into a contiguous 180 square kilometre land package enhances the potential for discovering additional deposits along the Munni Munni Fault and related structures.

Looking Ahead

Assay results from the current drilling are expected progressively through the second quarter of 2026. The company’s ability to dynamically adjust drilling targets based on incoming data will be key to maximising exploration success. With high-grade silver mineralisation close to surface and near existing processing infrastructure at the nearby Radio Hill site, Elizabeth Hill is shaping up as a compelling development opportunity in Australia’s silver sector.
