Brightstar Resources (ASX:BTR) has provided a progress update on its flagship Sandstone Gold Project in Western Australia, advancing its two-year strategic plan to establish a district-scale, long-life production hub.
Following the acquisition of Aurumin in December 2025, Brightstar now controls over 4.0Moz of mineral resources across its Sandstone and Goldfields hubs, completing its M&A consolidation strategy and shifting focus entirely to operational delivery and project development.
Three drilling rigs are being mobilised to Sandstone to commence 2026 infill and extensional drilling, with 19km of infill drilling expected to be completed this March quarter for inclusion in the pre-feasibility study, targeted for delivery in early September.
Sandstone hosts a total mineral resource of 2.4Moz at 1.5g/t Au, including 1.6Moz within 150m of surface, supporting predominantly open pit mining.
Subsequent drilling in 2026 will focus on growth targets to expand the mineral resource base.
Brightstar’s Sandstone strategy centres on three pillars: upgrading mineral resources through drilling, converting resources to a maiden ore reserve supported by technical studies, and right-sizing processing infrastructure with a 4–5Mtpa plant to optimise recoverable gold and support open pit and underground production.
The Two Mile Hill underground deposit offers potential high-grade feed to complement open pit sources.
Brightstar plans a definitive feasibility study in H2 2027, aiming for a final investment decision and project development by year-end 2027.
Managing Director Alex Rovira noted Sandstone's underexplored potential and its role in delivering a large-scale, growth-focused gold operation.
