West Coast Silver Accelerates Drilling to Unlock Elizabeth Hill’s Hidden Silver Riches

Accelerated Drilling to Build on Bonanza-Grade Results

West Coast Silver Limited (ASX – WCE) is moving swiftly to capitalise on the promising results from its initial drilling campaign at the Elizabeth Hill Silver Project in the Pilbara region of Western Australia. The company announced the commencement of an accelerated Phase 2 diamond drilling program starting 10 October 2025, aiming to confirm and extend the very high-grade silver mineralisation discovered near surface and test deeper down-plunge targets that remain open at depth.

Dual Focus – Near-Surface Continuity and Down-Plunge Potential

The Phase 2 program is designed with a twofold objective. First, it seeks to demonstrate the continuity of near-surface silver mineralisation within the oxide zone adjacent to historic workings. Second, it aims to explore a deeper target to the south, which geological and historical drilling data suggest could represent a down-plunge repeat of the Elizabeth Hill mineralised system. Approximately 14 diamond drill holes totaling around 1,300 metres are planned initially, with scope to expand based on early results.

Supporting Air Core Drilling and Advanced Geophysics

Complementing the diamond drilling, West Coast Silver plans an additional ~3,000 metres of air core drilling scheduled to commence in early November. This program will target near-mine anomalies identified through recent geophysical surveys. The company is currently conducting drone magnetic and Transient Electromagnetic (TEM) surveys to refine drill targets along the prospective Munni Munni Fault and parallel structures, enhancing the precision of exploration efforts.

Historical Data Underpinning Exploration Confidence

Historical underground diamond drilling at Elizabeth Hill has revealed spectacular silver grades, including intercepts such as 2 metres at 1,995 grams per tonne silver within a broader 6-metre interval averaging 705 grams per tonne. These results, alongside geochemical signatures of associated base metals, reinforce the prospectivity of the down-plunge targets. West Coast Silver is leveraging these legacy data sets, validated by a Competent Person, to guide its current exploration strategy.

Strategic Location and Growth Potential

Elizabeth Hill is situated in a Tier 1 mining jurisdiction on a consolidated land package spanning approximately 180 square kilometres. The project benefits from a proven production history, having yielded 1.2 million ounces of silver at an extraordinary head grade of 2,194 grams per tonne before mining ceased in 2000 due to low silver prices. The proximity to potential processing infrastructure at the nearby Radio Hill site adds to the project's strategic appeal. With mineralisation open at depth and multiple structural targets along the Munni Munni Fault system, West Coast Silver is well positioned to expand its resource base.

Executive Chairman Bruce Garlick emphasised the company's momentum – “We’re back on the ground and moving quickly to build on the outstanding grades from our initial campaign. Phase 2 is designed to do two things – demonstrate near-surface continuity in the oxide zone and test a deeper target that could represent a down-plunge repeat of the Elizabeth Hill system.”
