Sinclair said the reported assays were received after the 31 July 2026 resource cut-off and lie outside the updated 1.8Moz resource. The company said both Mt Henry and Selene remain open at depth and along strike, while five rigs continue drilling across the deposits.
At Selene, Sinclair reported intersections of 41.1m at 1.1g/t gold from 194.9m, including 24.9m at 1.5g/t gold, and 16.0m at 1.2g/t gold from 222.0m, including 6.3m at 2.1g/t gold. The company said the latest results extended known mineralisation by about 75m beyond the current resource boundary.
At Mt Henry, the company reported intersections including 18.0m at 1.8g/t gold from 315.0m, including 7.0m at 4.0g/t gold; 23.0m at 1.4g/t gold from 239.0m; and 13.0m at 1.8g/t gold from 324.0m. Sinclair said drilling had extended known mineralisation by up to about 100m beyond the resource boundary, with an intersection a further approximately 180m beyond the boundary in the deposit's central section.
Sinclair plans to continue step-out drilling at Mt Henry and Selene through 2026, with assays pending from 33 holes outside the current resource footprint. The company is targeting its next Mineral Resource update before the end of FY27.
