Brightstar’s new Sandstone gold targets: corridor focus and design notes for planners
Reviewed by Tom Sullivan

First reported on Australian Mining
30 Second Briefing
Brightstar Resources has defined 11 priority gold targets along the Two Mile Hill–Bull Oak corridor within its 3.6-million-ounce Sandstone project in Western Australia, with drilling scheduled to start in November. The targets were generated by integrating geological mapping with geophysical datasets to pinpoint mineralisation analogous to the existing Two Mile Hill system. For geologists and mine planners, the work concentrates exploration along a specific structural corridor, potentially extending known ore shoots and influencing future resource modelling and mine design at Sandstone.
Technical Brief
- Corridor work focuses on the Two Mile Hill–Bull Oak structural trend within the Sandstone tenure.
- Targeting is explicitly analogue-based, seeking repetitions of the known Two Mile Hill intrusive-hosted system.
- Geological mapping has been integrated with multiple geophysical datasets rather than relying on drilling alone.
- Similar analogue-driven targeting along defined structural corridors is now common on mature Archaean goldfields in WA.
Our Take
The 3.6Moz resource at Brightstar’s Sandstone gold project now sits alongside the recently reported 1.45Moz at Two Mile Hill–Shillington, signalling that Western Australian ounces are consolidating across multiple deposits rather than a single flagship pit.
Our database shows several recent Brightstar items focused on deep drilling at Two Mile Hill–Shillington and thick mineralised intercepts at Bull Oak, so the 11 new priority targets along the Two Mile Hill–Bull Oak corridor likely aim to stitch these discoveries into a continuous, multi-decade mining corridor.
With Brightstar also advancing the Laverton Goldfields development towards first gold in 2027, incremental discoveries at Sandstone in Western Australia could materially influence how the company sequences feed between Sandstone and the new Laverton processing hub.
