West Coast Silver Limited has intersected 67.1 metres grading 19 g/t silver from surface in diamond drill hole 26WCDD036 at the Elizabeth Hill project, extending a broad near-surface silver zone west of the current Mineral Resource Estimate block model.

The latest assay results from holes 26WCDD031 through 26WCDD036 confirm and expand a broad, near-surface zone of low- to moderate-grade silver mineralisation located north and west of the April 2026 Mineral Resource Estimate block model. Hole 26WCDD036 included internal higher-grade intervals of 12.3 metres at 22 g/t silver from 24.7 metres and 10.9 metres at 24 g/t silver from 43.9 metres down hole, alongside a 1-metre intercept of 97 g/t silver from 59.1 metres.

Additional significant intersections from the programme include hole 26WCDD035, which returned 48.5 metres at 19 g/t silver from 1.5 metres down hole, including 25.5 metres at 23 g/t silver from 16 metres. Hole 26WCDD033 intersected 24 metres at 14 g/t silver from 35.5 metres down hole, including 2.7 metres at 22 g/t silver.

At Elizabeth Hill Deeps, diamond drill hole 26WCDD030 targeted the potential continuation of high-grade silver mineralisation below historical underground workings. The hole intersected minor silver mineralisation of less than 10 g/t silver while testing the northern extent of the newly identified deeper zone, which remains open to the east and south.

“The latest drilling results continue to confirm that silver mineralisation at Elizabeth Hill extends beyond the historical underground mine and is associated with a broader mineralised structural corridor along the Munni Munni Fault.

When combined with earlier 2026 RC results, the footprint of lower grade mineralisation north and west of the existing MRE has been expanded and infilled but not closed out. This shows that a significant volume of lower grade mineralisation is zoned about higher grade silver, increasing the potential for additional contained silver at lower grades.”

Final diamond core assays for holes 26WCDD037 to 26WCDD039 are expected by the end of August 2026. Those results will feed into an updated JORC 2012 Mineral Resource Estimate for Elizabeth Hill scheduled for the fourth quarter of 2026, alongside a scoping study also set to commence in the fourth quarter of 2026.
