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.

OM1: Annual Report to Shareholders

Omnia Metals Group Ltd pivoted its strategy to focus on critical minerals in the US, acquiring the Stibnite Ridge Antimony and Silver Project and staking the Radix REE and Gallium Project in Montana, supported by $3.1 million in capital raises. Initial reconnaissance at Radix identified high-priority REE-Nb targets, while drilling at the Salt Creek Gold Project in Australia returned no significant mineralization. The company also entered a JV for the Corvette Project, which has historical high-grade gold intercepts, and continues to hold an earn-in interest in a Canadian lithium project.
