West Coast Silver Limited has intersected bonanza-grade silver at the Elizabeth Hill project in Western Australia, returning 38.3 metres at 878 grams per tonne silver from just 3.7 metres downhole in diamond drill hole 26WCDD037.

The latest assays conclude the company's first-half drilling program at the project, which previously produced 1.2 million ounces of silver from 16,830 tonnes at an average grade of 2,194 grams per tonne prior to closing in 2000.

The hole included a 22.3-metre interval grading 1,495 grams per tonne silver from 19.7 metres downhole, which featured a 1.4-metre section at 23,360 grams per tonne from 29.0 metres, including 0.5 metres at 64,745 grams per tonne. A deeper interval within the same hole returned 13.5 metres at 2,253 grams per tonne silver from 45.0 metres, including 9.15 metres at 3,318 grams per tonne. High-grade intervals in hole 26WCDD037 contained visible native silver alongside silver sulphide minerals.

Additional drilling from the completed program confirmed broad near-surface mineralisation outside the project's current mineral resource estimate block model. Drill hole 26WCDD038 intersected 63.0 metres at 53 grams per tonne silver from 2.0 metres downhole, including 31.3 metres at 92 grams per tonne from 26.7 metres. Hole 26WCDD039 returned 20.15 metres at 53 grams per tonne silver from 15.0 metres downhole.

The holes tested a new west-to-east orientation, collaring west of the historic underground workings to evaluate mineralisation extending into the surrounding granite.

“Importantly, changing the drilling orientation from west-to-east and collaring holes west of the historic Elizabeth Hill underground workings has highlighted mineralisation that had not been extensively tested by previous drilling. This opens a new near-surface area of mineralisation extending westward into the granite and will be assessed for its contribution to the planned Mineral Resource update.” — Sergei Smolonogov, CEO

The new assay data will be incorporated into an updated JORC 2012 mineral resource estimate scheduled for release in the fourth quarter of 2026. West Coast Silver also plans further west-to-east oriented diamond drilling during the second half of 2026 to improve geological and grade confidence across the deposit.

Elsewhere in the surrounding district, GreenTech Metals Limited commenced an 8,300-metre reverse circulation and diamond drilling program at the Munni Munni project on 3 August 2026.
