Westar Resources Limited (ASX: WSR) has successfully intersected high-grade gold in the maiden drill reverse circulation (RC) programme at the Olga Rocks Project in Western Australia.
Hole OLRC013 returned 3.0m @ 7.5g/t Au, including 1.0m @ 21.7g/t Au. This hole verified the historical drilling and a further three holes targeting lithium mineralisation returned additional significant intercepts of 12m @ 3.5g/t Au, including 4.0m @ 9.9g/t Au in hole OLRC014 from 88m.
Westar Executive Director Lindsay Franker said the company is encouraged by these results particularly given Olga Rocks is located within the world-class Southern Cross Greenstone belt, the extensive historical mining within the tenements and the advantages inherent in utilising historical drilling in drill planning. Open along strike and at-depth, analysis has already commenced with targeting further drilling being finalised ahead of a planned program due to commence in Q3-2023, subject to appropriate approvals.
Westar is excited to successfully intercept high-grade gold, over significant thicknesses with our maiden RC program at Olga Rocks,” Mr Franker said.
“With the validation of gold at Olga Rocks, Westar is planning the next phase of drilling, to further test the gold potential within the prospective high iron basalt units running through the tenement package. Whilst awaiting the imminent lithium assays, Westar geologists will continue to advance exploration targeting for buried pegmatites across the Olga Rocks tenure.”
Next Steps
Following successfully validating the historic gold intercepts and identifying three new gold targets with the maiden RC programme at Olga Rocks, a follow-up RC programme is planned to further test the gold potential within the prospective high iron basalt units running through the tenement package.
Historically the iron formation unit has produced gold lodes which have been subsequently mined e.g. Centenary (>19 koz Au)5 as well as known mineralisation at Buffalo and Spring Hill and hosts current exploration targets including Dulcie North and Dulcie Far North, all along strike of the Olga Rocks tenement package.
The maiden drill programme has indicated portions of the Olga Rocks pegmatite is situated alongside the gold mineralised unit, allowing both commodities to be tested in one drill program. Further drilling along strike is planned where the gold mineralised basaltic unit can be traced using surface mapping and magnetic survey data.
