IP Survey & RC Drilling Results at Rhyolite Dome
Great Western Mining Corporation PLC has completed an IP geophysical survey and RC drilling at its Rhyolite Dome prospect within the Olympic Gold project, identifying a near-surface resistivity anomaly and a deeper chargeable feature. Four shallow RC holes totalling 706 meters intersected altered volcanic rocks, returning low-grade gold and more significant silver mineralization, including 21.3 meters at 1.64 g/t Ag. Elevated pathfinder elements suggest shallow hydrothermal system levels, and the company will refine its geological model to target the deeper anomaly. Disclaimer*

The Great Western team regards Rhyolite Dome, one of the eight currently identified prospects across the 800 acre (324 ha) claims area, to be a prospect that merits further assessment and, in the second half of 2025, four initial shallow holes were drilled following an IP survey to launch a maiden exploration programme. While this first-pass drilling didn't return significant precious-metal intercepts, it has materially advanced our geological understanding. Combined with the high-quality geophysical dataset, these results provide a strong technical foundation to refine targeting and design the n...
