• Significant assays include 411m @ 1.11g/t Au, 162.3m @ 1.38g/t Au, and 147.7m @ 1.01g/t Au at Two Mile Hill-Shillington deposit
• Whistler deposit returned 31m @ 5.17g/t Au and 13m @ 3.54g/t Au
• Lord Nelson deposit had 16m @ 1.49g/t Au and 5m @ 2.15g/t Au

Brightstar Resources has received results from diamond and reverse circulation drilling completed at the 2.4Moz @ 1.5g/t Au Sandstone Gold Project. The drilling was designed to infill key deposits and test for growth extensions. Significant assays include 411.2m @ 1.11g/t Au, 162.3m @ 1.38g/t Au, and 147.7m @ 1.01g/t Au at the Two Mile Hill-Shillington deposit, which hosts a current Mineral Resource of 664koz @ 1.6g/t Au and remains open at depth. The deposit is a potential bulk-tonnage underground mining operation to provide higher-grade ore within the proposed multi-ore source processing hub at Sandstone. At the Whistler deposit, drilling returned 31m @ 5.17g/t Au, 13m @ 3.54g/t Au, and 13m @ 3.32g/t Au. The Lord Nelson deposit had significant intercepts of 16m @ 1.49g/t Au and 5m @ 2.15g/t Au. The latest results will be incorporated into the upcoming Mineral Resource Estimate update and the ongoing Pre-Feasibility Study work.

The company expects to release a Mineral Resource Estimate update for the Sandstone Gold Project in JunQ'26, with the Pre-Feasibility Study targeted for delivery in 2H'CY26.

Brightstar's Managing Director commented that the drilling results clearly highlight the potential scale of the Sandstone project, with the Two Mile Hill-Shillington deposit shaping up to be a significant contributor to a future Sandstone operating hub. The company's ongoing drilling and feasibility study work at the Sandstone Hub continues to progress.
