West Coast Silver Extends Elizabeth Hill Mineralisation 70m Beyond Maiden Resource

Significant Resource Expansion Confirmed at Elizabeth Hill

West Coast Silver Limited (ASX:WCE) has revealed that its recent reverse circulation (RC) drilling campaign at the Elizabeth Hill Project in Western Australia has pushed silver mineralisation 70 metres north beyond the April 2026 maiden Mineral Resource Estimate (MRE). The first 17 of 32 holes assayed in the May 2026 program show broad, near-surface silver zones and high-grade intersections, reinforcing the prospectivity of the deposit which remains open both along strike and at depth.

Standout results include a 60-metre intersection grading 25 g/t silver from surface (including 19m at 31 g/t) in hole 26WCRC004, and a 28-metre run averaging 29 g/t silver from 2 metres downhole in 26WCRC002, which ended in mineralisation due to challenging ground conditions. Additionally, high-grade hits of 1m at 157 g/t silver from surface and 2m at 96 g/t silver from 91m depth were recorded in holes 26WCRC011 and 26WCRC012 respectively. These results confirm that the mineralised system is not only larger than previously modelled but also contains zones of potentially economic grade.

Lead Mineralisation Highlights Deeper Potential

Alongside silver, the drilling intersected lead mineralisation up to 1.66% Pb in hole 26WCRC010, consistent with Elizabeth Hill’s known spatial association between lead and silver. This relationship suggests the possibility of discovering higher-grade silver zones further along the Munni Munni Fault Zone (MMFZ), the main structural control for mineralisation. A particularly notable hole, 26WCRC023, logged 72 metres of altered MMFZ but awaits assay results, representing the widest fault zone intersection drilled to date at Elizabeth Hill North.

Diamond Drilling and Development Studies Underway

To complement the RC drilling, diamond drilling is in progress targeting zones where RC holes terminated in mineralisation, aiming to better define the system at depth. Parallel economic studies are advancing to evaluate potential development pathways, leveraging the project's historical high-grade production and low-cost gravity processing potential.

Elizabeth Hill boasts a production history of 1.2 million ounces of silver at an extraordinary head grade of 2,194 g/t, mined from a modest 16,830 tonnes of ore. Mining ceased in 2000 due to low silver prices, but current market conditions and the expanding resource footprint are materially improving the project’s economics. The project benefits from a strategic location in the Pilbara, granted mining leases, and an MOU with Artemis Resources to assess the nearby Radio Hill processing facility as a treatment option.

Ongoing Exploration Targets Beyond Elizabeth Hill

West Coast Silver is also focusing on regional exploration prospects along the MMFZ, including the Maitland and Elizabeth Hill South prospects. The company plans further drilling to infill lower-density areas within the MRE, test strike extensions, and explore newly identified targets in the project’s northwest. Surface and downhole geophysical surveys using IP, CSAMT, EM, and downhole EM methods are planned to support these efforts.

Executive Director Bruce Garlick emphasised the growing scale of the silver system, noting the discovery of silver mineralisation in granite as a promising development that broadens the geological prospectivity. With several assay results still pending and diamond drilling ongoing, the company is building a compelling case for resource growth and a clear development pathway.

While the true widths of mineralisation remain unreported and some assay results are awaited, these latest results provide a strong foundation for an upgraded resource estimate and economic evaluation later in 2026. The evolving picture at Elizabeth Hill suggests a deposit with expanding scale and grade potential, supporting West Coast Silver’s ambition to advance the project towards production.
