This target emerged from detailed geological mapping and surface channel sampling that indicated a strong structural control on higher-grade gold distribution (see news release dated October 7, 2025). MC25-232 successfully confirmed this interpretation, delivering the widest continuous interval of gold mineralization encountered at Argus North to date, returning 208.0 meters (\"m\") grading 2.3 grams per tonne gold (\"g/t Au\"), while extending the southern footprint of the zone by an additional 50 metres.Step-out drilling continues to systematically expand the Argus North mineralized system along strike and to depth. Recent holes have returned multiple broad and high-grade intercepts (see news releases dated April 10, June 26, July 23, September 3, October 7, and October 22, 2025), including 69.6 m grading 3.4 g/t Au in the initial discovery hole MC25-232.New Highlights from Argus North208.0 m grading 2.3 g/t Au, in drill hole MC25-232, including 54.4 m grading 3.3 g/t Au, including8.0 m grading 5.0 g/t Au, and4.0 m grading 5.8 g/t Au2.0 m grading 5.5 g/t Au4.0 m grading 4.3 g/t Au24.9 m grading 5.2 g/t Au, including12.0 m grading 7.2 g/t Au, and3.0 m grading 7.5 g/t AuOngoing step-out drilling at Argus North, combined with mechanical stripping and channel sampling, has continued to demonstrate wide intervals of gold mineralization over >150 meters of strike length and from surface to >350 meters vertically. The Argus North Zone remains open along strike, down-dip, and down-plunge. The Company has completed 81 drill holes to date (assays announced for 37 holes) completing the previously announced ...
