• Significant assays received from diamond drilling at the Musketeer, Indomitable and Vanguard deposits
• Musketeer drilling returned high-grade intercepts up to 26.7g/t Au over 4.2m
• Indomitable drilling intersected zones of strong sericite alteration and quartz veining with assays up to 11.7g/t Au over 6.5m

Brightstar Resources has received results from its maiden diamond core drilling (DD) program at the 2.4Moz @ 1.5g/t Au Sandstone Hub, completed in late 2025. The drilling was designed to infill key deposits, the subject of ongoing Pre-Feasibility Study (PFS) work streams, as well as test for growth extensions along strike and down dip. Significant assays were received from the Musketeer, Indomitable and Vanguard deposits. At Musketeer, the drilling intersected zones of altered banded iron units (BIFs) with felsic porphyry intrusions, returning high-grade intercepts up to 26.7g/t Au over 4.2m. The Indomitable deposit is hosted within a deeply weathered ultramafic unit, with mineralisation associated with stratigraphy-parallel northwest-dipping lodes as well as north-south oriented lodes. The DD holes intersected zones of strong sericite alteration with quartz veining, with assays up to 11.7g/t Au over 6.5m. Assays remain outstanding for DD completed at the Vanguard, Bull Oak, Lord Henry, Lord Nelson, and Two Mile-Hill-Shillington Deposits, with drilling ongoing. Brightstar is fully funded to comprehensively drill out the Sandstone Gold Project, undertake all feasibility study assessments and permitting activities, to advance Sandstone to Final Investment Decision.

Brightstar is targeting a Mineral Resource Estimate upgrade for the Sandstone Project in JunQ'26.

Brightstar's 2026 drilling campaign is now well underway with two RC and two DD rigs drilling at Sandstone to complete the last of the infill drilling for PFS work streams, and commence extensional drilling targeting growth to the Mineral Resources.
