West Coast Silver has reported final assay results from its first-half 2026 diamond drilling program at the Elizabeth Hill Silver Project in Western Australia's West Pilbara.
The 27 August 2026 results were led by 38.3 metres at 878 grams per tonne silver from 3.7 metres downhole in 26WCDD037. That interval included 22.3 metres at 1,495g/t from 19.7 metres and 1.4 metres at 23,360g/t, including 0.5 metres at 64,745g/t.
Mineralisation extended beyond the resource
West Coast Silver said holes 26WCDD037 to 039 intersected mineralisation outside the current Mineral Resource estimate, extending the system towards surface and westward into granite. The drilling also confirmed high-grade mineralisation within and below the existing resource model.
Hole 26WCDD038 returned 63 metres at 53g/t silver from two metres, including 31.3 metres at 92g/t from 26.7 metres. The company cautioned that reported intervals are downhole lengths and not true widths.
Elizabeth Hill's April 2026 Mineral Resource estimate contains 141,000 tonnes at 617g/t silver for 2.8 million ounces at a 20g/t cut-off. The project sits on granted Mining Lease M47/342 about 45 kilometres south of Karratha.
Further drilling and resource work planned
The new assays will be incorporated into geological modelling and are expected to inform a planned JORC 2012 Mineral Resource update in the fourth quarter of 2026.
West Coast Silver is planning further west-to-east diamond drilling during the second half of 2026. The program is intended to improve resource classification, test the limits of near-surface granite-hosted mineralisation and further assess high-grade zones within the current resource area.
The company also plans economic studies on the near-surface mineralisation after the resource update. Continued drilling, modelling and evaluation may create future requirements across exploration, geology, resource definition and project studies, subject to the company's program and development decisions.
