Material early-stage aircore drilling success at Sandstone

• Significant gold assays from first-pass aircore drilling at Indomitable North and Bollinger prospects
• Indomitable North returned 24m @ 3.97g/t Au from 48m, including 8m @ 10.4g/t Au
• Bollinger returned 12m @ 2.08g/t Au from 124m, including 4m @ 5.60g/t Au

Brightstar Resources has announced the results of an aircore drilling program at its Sandstone project, which hosts a current Mineral Resource Estimate of 2.4Moz @ 1.5g/t Au. The drilling targeted early-stage prospects across the project, with the most significant results coming from the Indomitable North and Bollinger prospects. At Indomitable North, located approximately 500m from the existing 0.3Moz Au Indomitable Mineral Resource, the drilling returned several high-grade intercepts, including 24m @ 3.97g/t Au from 48m, including 8m @ 10.4g/t Au from 60m in SSAC25199. The Bollinger prospect, located 1.5km from Indomitable, also produced encouraging results, with 12m @ 2.08g/t Au from 124m, including 4m @ 5.60g/t Au from 124m in SSAC25224. These results have provided high-priority targets for follow-up RC drilling in Brightstar's 2026 exploration campaign. The company's exploration team continues to apply targeting principles across the broader Sandstone project, and the early-stage exploration activities remain a priority, running in parallel with infill and resource definition drilling and feasibility study work.

The exploration team continues to apply targeting principles to the Sandstone project as a whole, so it is exciting to consider what new prospects will be proposed for near-term testing. The early-stage targeting and exploration activities remain a priority for the exploration team and continue in parallel with infill and resource definition drilling and feasibility study work.
