West Coast Silver (ASX:WCE) has mobilised a diamond rig to the historical Elizabeth Hill mine in the Pilbara to test down-dip and plunge extensions of its very high-grade silver system.
The campaign is designed to probe six holes totaling up to 1,500m and, for the first time, systematically test whether the Munni Munni Fault hosts repeat high-grade shoots at depth — a finding that could materially expand the system beyond the old workings. All holes are planned to intersect the Munni Munni Fault within roughly 200m of surface.
Drilling is expected to take four to six weeks, with assay results arriving progressively through Q2 2026.
Alien Metals (AIM: UFO, FWB: I3A1) retains a 30% interest in Elizabeth Hill via its joint venture with Crest, giving Alien exposure to any upside from successful drilling.
"Our previous 2025 drilling confirmed that silver mineralisation at Elizabeth Hill extends beyond the historical underground mine and associated with a broader structural corridor along the Munni Munni Fault," said Bruce Garlick, Executive Chairman of West Coast Silver.
For context, historical production at Elizabeth Hill totalled 1.2Moz of silver from just 16,830t at a head grade of 2,194g/t Ag.
