Brightstar Resources has reported impressive high-grade gold assay results from its 2025 drilling campaign at the Sandstone Hub, setting the stage for a significant Mineral Resource upgrade and Pre-Feasibility Study later this year.
- High-grade gold assays up to 125g/t from 2025 reverse circulation drilling
- Drilling targeted key deposits – Achilles North, Lord Henry, Vanguard, Shillington-Two Mile Hill
- Results support upcoming Mineral Resource upgrade scheduled for June 2026
- Pre-Feasibility Study on track for early September 2026 delivery
- 2026 drilling campaign underway to extend and infill resources
Strong Drilling Results Reinforce Sandstone’s Potential
Brightstar Resources Limited (ASX, BTR) has released a detailed update on its 2025 reverse circulation (RC) drilling program at the Sandstone Hub in Western Australia, home to a current Mineral Resource Estimate of 2.4 million ounces at 1.5 grams per tonne gold. The drilling campaign, focused on key deposits including Achilles North, Lord Henry, Vanguard, and Shillington-Two Mile Hill, has delivered high-grade gold intercepts that underscore the project’s robust growth potential.
Among the standout results, the Achilles North deposit yielded an exceptional 3 metres at 42.5g/t gold from 158 metres, including a remarkable 1 metre at 125g/t. Similarly, Lord Henry returned multiple high-grade hits such as 5 metres at 10.7g/t from 57 metres and 2 metres at 9.04g/t from 46 metres. These results not only confirm the quality of existing mineralisation but also hint at extensions beyond the current resource boundaries.
Strategic Infill and Extension Drilling
The 2025 drilling was designed to both infill and test for extensions along strike and at depth, providing critical data to underpin Brightstar’s forthcoming Mineral Resource upgrade, expected in the June quarter of 2026. This upgrade will feed directly into the Pre-Feasibility Study (PFS), targeted for completion in early September 2026, which aims to refine mine planning and development strategies.
Brightstar’s Managing Director, Alex Rovira, highlighted the significance of these results, noting that the high-grade intercepts from extensional drilling are vital for de-risking the project and supporting the upcoming resource and feasibility milestones. The company’s recent capital raising has bolstered its financial position, enabling an accelerated exploration and development program at Sandstone.
Ongoing Exploration and Future Outlook
With diamond drilling assays from 2025 still pending, Brightstar has already commenced its 2026 drilling campaign, deploying both RC and diamond rigs to complete infill drilling and pursue resource growth. The Sandstone Hub’s extensive tenure of approximately 1,800 square kilometres in underexplored greenstone belts presents significant upside potential.
Brightstar’s strategy is clear, to rapidly grow and upgrade the Sandstone resource base, advancing it towards becoming a meaningful gold production hub in Western Australia. The company’s portfolio, supported by strong infrastructure and a favourable jurisdiction, positions it well for future development and production phases.
As the market awaits the Mineral Resource upgrade and PFS results, these drilling outcomes provide a compelling narrative of exploration success and project momentum.
Bottom Line?
Brightstar’s high-grade drilling results at Sandstone set a promising foundation for resource growth and project advancement in 2026.
Questions in the middle?
