New gold deepens Sandstone potential
What happened
Brightstar Resources reported visible gold hits during a deep drilling campaign at the Two Mile Hill deposit in Sandstone, Western Australia. The campaign is an active, ongoing reverse circulation and diamond program targeting deeper sections to support a pre‑feasibility study, making it operationally real for local underground planning. Watch whether the program converts to sustained underground development scopes that need contractors and long‑lead equipment
Buyer takeaway
This is an in‑region, executable demand signal: drilling that supports underground development typically pulls in contractors, ventilation, ground support, and specialist plant
Cost / money
Expect upward pressure on specialist underground rates and potential mobilisation premiums as local contractor capacity is consumed by drilling then development
Supplier / commercial
Local drilling and potential follow‑on underground works give suppliers leverage on mobilisation timing and quote validity; split pricing and staged awards help maintain comparability
Safety / operations
Deeper drilling increases HSE interface needs (site inductions, emergency response planning, geotechnical controls) that must be written into contractor scopes
What to watch
Watch whether drilling converts to sustained underground development and whether contractors start restricting availability or shortening quote windows
Key facts
- Ongoing 9,100m reverse circulation and diamond drilling campaign
- Drilling targets extend to depths beyond 550m
- Activity intended to support a pre‑feasibility study

Brightstar’s ongoing 9100m reverse circulation and diamond drilling campaign is targeting deeper sections of the resource to support a higher-confidence classification for inclusion in the project’s pre-feasibility study, due in the second half of 2026. “The intersection of visible gold in drilling is always exciting,” Brightstar managing director Alex Rovira said
” The drilling program extends to depths of more than 550m below surface, targeting areas identified as prospective for underground mining beneath the planned open pits. Rovira said studies assessing a large-scale underground development were already underway alongside optimisation work across the broader Sandstone project
This is particularly encouraging for the potential economic viability of a future underground operation. ” The drilling program extends to depths of more than 550m below surface, targeting areas identified as prospective for underground mining beneath the planned open pits
