• Significant high-grade gold intercepts from diamond and RC drilling at the Sandstone Gold Project
• Drilling focused on infilling and extending key deposits for upcoming Mineral Resource update and Pre-Feasibility Study
• Ongoing drilling with 4 rigs continuing to advance the project

Brightstar Resources has announced results from diamond core (DD) and reverse circulation (RC) drilling programs at the Sandstone Gold Project, which hosts a current Mineral Resource Estimate of 2.4Moz @ 1.5g/t Au. The drilling targeted infill and extensional work at several key deposits across the Sandstone Hub, including Bull Oak, Vanguard, Havilah, Achilles, and the Indomitable Camp. Significant assays were returned, including 214.75m @ 0.97g/t Au from 32.75m, 10.82m @ 2.91g/t Au from 271.68m, and 7m @ 17.7g/t Au from 138m at the Bull Oak deposit. The diamond drilling also provided key structural, geotechnical, and metallurgical data for the ongoing Pre-Feasibility Study. Drilling is ongoing with 4 rigs active, focused on infilling areas below the existing Mineral Resource to facilitate an upgrade, as well as extensional growth-focused drilling. The Sandstone Mineral Resource upgrade is expected mid-year, with the Pre-Feasibility Study targeted for delivery in the second half of 2026.

The company expects to deliver a Mineral Resource upgrade and Pre-Feasibility Study for the Sandstone Gold Project in the second half of 2026.
