Brightstar Resources hits high-grade gold at Sandstone, bulk-tonnage potential grows

Brightstar Resources (ASX:BTR) keeps adding evidence that its Sandstone gold project in Western Australia is more than a collection of deposits. Results from diamond and reverse circulation drilling programs, released this week, show high-grade continuity at depth within broader lower-grade envelopes – the same pattern that makes the Two Mile Hill-Shillington deposit work.

Managing Director Alex Rovira said the Bull Oak drilling confirms that geology. "High-grade continuity at depth within extensive lower-grade mineralised envelopes, emulating the geology and mineralisation observed at Two Mile Hill-Shillington," he said. The two deposits sit within five kilometres of the proposed plant site.

Achilles, another deposit in the Sandstone Hub, is also delivering. Rovira said drilling there "continues to exceed expectations" with consistent mineralisation across both mafic and granitic rock types. That matters for the resource classification. The company wants to convert a substantial portion of Achilles to the Indicated category, which would de-risk the development pathway ahead of a Pre-Feasibility Study due later this calendar year.
