• Bonanza-grade silver intercepts up to 33,107 g/t Ag
• Maiden Mineral Resource Estimate of 2.79Moz silver
• Aggressive drilling program underway to expand resource

West Coast Silver has focused on delivering further high-grade drilling results while advancing exploration and technical work programs across the Elizabeth Hill Silver Project. During the quarter, the company commenced an aggressive drilling program aimed at expanding the footprint of silver mineralisation, identifying new exploration targets and progressing the project toward resource definition and potential resource development studies. Subsequent to the quarter, the company released its inaugural Mineral Resource Estimate, establishing Elizabeth Hill as a high-grade silver project and providing a clear pathway toward economic evaluation and development studies. The Mineral Resource Estimate comprises 141kt at 617 g/t Ag for 2.79Moz of contained silver. The company has also commenced a diamond drilling program targeting down-dip and down-plunge extensions of high-grade silver mineralisation beneath the historical Elizabeth Hill mine, and identified a new high-priority drill target at Elizabeth Hill following the application of Down Hole Electromagnetics. The company's focus during the quarter was on exploration at the Elizabeth Hill Silver Project, where it continued to advance exploration and target generation following the highly encouraging results from the 2025 diamond drilling campaign. The company released bonanza-grade silver assay results, completed detailed geophysical surveys which identified multiple new exploration targets, and commenced an RC drilling program of up to 4,000m designed to expand the footprint of high-grade silver mineralisation at Elizabeth Hill.

The company is well positioned to accelerate exploration across Elizabeth Hill and to continue growth beyond the current maiden Elizabeth Hill Mineral Resource Estimate. The work completed this quarter reinforces the company's belief that Elizabeth Hill has the potential to emerge as one of Australia's most significant high-grade silver discoveries.
