High-Grade Discovery At The 1350 Zone

VANCOUVER – Metallis Resources Inc. reported the discovery of high-grade mineralization from the Company’s inaugural diamond drilling program on the Greyhound Property in central Idaho. This program was designed to test three priority targets along the 3.5 km shear zone, with many other high potential targets remaining untested. The first three drill holes at the 1350 Zone have returned multiple high-grade intervals of silver and gold, accompanied by significant antimony (Sb), lead, and zinc mineralization. Highlights include: 0.54 meters (m) of 2,135 g/t AgEq (including 2.0% Sb) in GH25-05, and 1.90 meters of 514 g/t AgEq (including 0.50 m of 1,281 g/t AgEq) in GH25-07.

Fiore Aliperti, President and CEO, said, “This inaugural program has confirmed that the 1350 Zone is a robust, high-grade mineralized zone that warrants significant follow-up drilling to determine its full width, strike length, and vertical extent. The exceptional silver grades, combined with consistently strong gold values that were historically underappreciated, underscore the strength of this system. Antimony grades exceeding 5 percent further reinforce the critical-metal potential of Greyhound and add meaningful value in addition to the precious-metal endowment.

By identifying the position of the high-grade band within the thick shear and refining our understanding of the structural controls, the team has established a clear framework for expanding this discovery. As soon as seasonal access allows, we plan to return to build on these results and continue advancing what is shaping up to be a potentially transformative opportunity for Metallis and its shareholders. We are committed to unlocking its full value alongside our investors.”
