Brightstar Unifies Sandstone Gold Project with 2.4Moz Resource After Court Approval

Court Approval Finalizes Strategic Acquisition

Brightstar Resources Limited (ASX – BTR) has secured a critical milestone with the Supreme Court of Western Australia approving its acquisition of Aurumin Limited through a court-sanctioned share scheme of arrangement. This legal endorsement, expected to become effective on 21 November 2025, marks the first consolidation of the Sandstone Greenstone Belt under a single owner in over a decade.

The acquisition will see Aurumin’s shares and options absorbed into Brightstar’s structure, with Aurumin’s options cancelled and replaced by new Brightstar options. This move not only simplifies ownership but also strengthens Brightstar’s foothold in a historically fragmented gold district.

Significant Resource Growth and Exploration Momentum

Post-acquisition, the combined Mineral Resource Estimate (MRE) for the Sandstone Gold Project stands at approximately 2.4 million ounces of gold at a grade of 1.5 grams per tonne. When combined with Brightstar’s broader portfolio, the group’s total MRE rises to 3.9 million ounces, underscoring the scale of this consolidation.

Brightstar currently operates six drilling rigs at Sandstone, aggressively pursuing resource growth and upgrading confidence levels through infill drilling. With over 70,000 metres drilled in the past year and plans to extend drilling to around 120,000 metres before mid-2026, the company is positioning itself to deliver a Mineral Resource upgrade in the first half of next year.

Pathway to Development and Production Ambitions

Alongside exploration, Brightstar is advancing a consolidated Pre-Feasibility Study (PFS) for Sandstone, focusing on mining engineering, metallurgy, geotechnical studies, and regulatory approvals. The company targets a final investment decision (FID) for the project in the second half of 2027, aiming to fast-track development.

Brightstar’s Managing Director, Alex Rovira, highlighted the strategic importance of this consolidation, noting that Sandstone represents one of the largest undeveloped gold projects in Western Australia’s goldfields held by a junior company. The deposits are largely near surface, offering potential for both open pit and underground mining with a multi-decade mine life.

Complementing Sandstone, Brightstar’s existing Menzies-Laverton assets are poised for near-term production expansion. Together, these projects underpin Brightstar’s aspirational target of producing over 200,000 ounces of gold annually, a significant step toward becoming a mid-tier gold producer.

Looking Ahead

With the court approval now secured, Aurumin shares are expected to be suspended from trading on 21 November 2025, marking the formal completion of the transaction. Investors will be watching closely for the upcoming Mineral Resource upgrade and the results of the Pre-Feasibility Study, which will provide clearer insight into the economic viability and timeline of the Sandstone project’s development.
