Brightstar Resources Limited (ASX: BTR) has announced that the Supreme Court of Western Australia has approved the acquisition of 100% of Aurumin Limited's shares and options. The consolidated Mineral Resource Estimate (MRE) at the Sandstone Gold Project now stands at 2.4Moz @ 1.5g/t Au, with the group total MRE increasing to 3.9Moz @ 1.5g/t Au. Brightstar and Aurumin currently have six drilling rigs operating in Sandstone, targeting material MRE growth and infill drilling key deposits to enable an increase in confidence classification. A Mineral Resource upgrade for Sandstone is targeted for release in 1H CY26 following significant exploration drilling over the past 12 months (+70,000m completed to date). Workstreams are also progressing on the consolidated Pre-Feasibility Study, with mining engineering, metallurgical, geotechnical, approvals and permitting activities continuing to fast-track the eventual development of the Sandstone Gold Project, targeted for a Final Investment Decision in 2H CY27. The successful development of Sandstone, in conjunction with the near-term production expansion of Brightstar's Menzies-Laverton asset base, underpins Brightstar's aspirational production target of +200,000oz pa.

Brightstar aspires to be a leading mid-tier gold miner via a staged growth strategy, with current operations and proposed expansions providing a significant platform for growth. The development of the Menzies, Laverton, and Sandstone Gold Projects is central to delivering on Brightstar's vision and positioning the company as an emerging mid-tier Western Australian gold producer.
