West Coast Silver Ltd. has reported significant broad, near-surface drill intercepts from its Elizabeth Hill project in Western Australia, expanding the silver mineralisation footprint beyond its current resource model.
Assays from the recent Elizabeth Hill North (EHN) diamond program confirmed extensive low to moderate-grade silver mineralisation starting from surface.
Standout intersections include 67.1 metres at 19 grams per tonne (g/t) silver from surface in hole 26WCDD036, which featured internal higher-grade zones of 12.3 metres at 22 g/t silver and 10.9 metres at 24 g/t silver.
Other notable results include 48.5 metres at 19 g/t silver from 1.5m downhole, including 25.5 metres at 23 g/t silver from 16 metres.
The shallow mineralisation is hosted within intensely silica-altered granite and quartz-carbonate veins along the Munni Munni Fault Zone.
Interpreted as a halo surrounding the historical high-grade silver core, this newly defined zone remains open in all directions and is expected to add volume and contained metal to the deposit.
At Elizabeth Hill Deeps, hole 26WCDD030 intersected minor silver, effectively constraining the northern boundary of a recently discovered high-grade zone beneath historical workings. The deeper high-grade system remains open to the east and south for follow-up targeting.
West Coast Silver Executive Director Sergei Smolonogov said the results demonstrate a much broader structural corridor than historically recognised.
“The footprint of lower grade mineralisation north and west of the existing MRE has been expanded and infilled but not closed out,” Smolonogov said.
“This shows that a significant volume of lower grade mineralisation is zoned about higher grade silver, increasing the potential for additional contained silver.”
Final diamond assays for the remaining three holes are expected by late August. The data will feed into an updated JORC mineral resource estimate and a scoping study, both scheduled for the fourth quarter of 2026.
The company also plans for further step-out and infill diamond drilling planned in the second half to advance conversion of Inferred to Indicated resources, and continue defining the new high-grade zone below historical mining.
