SNM: Northern drilling extends mineralisation beyond current MRE

Sentinel Metals Limited has reported additional drill results from its 2026 program at the Columbia Gold-Silver Project in Montana, USA, confirming broad gold mineralization and extending it beyond the current Mineral Resource pit shell. Notable intercepts include 21.7m at 2.19g/t Au from DDCO26-011 and 9.1m at 2.56g/t Au from DDCO26-010, with some mineralization lying outside the existing pit shell. These results, along with pending assays for the final four holes, will be incorporated into an updated Mineral Resource Estimate in November 2026.
