The updated mineral resource estimate shows measured and indicated resources rising to 3.73 million tonnes grading 7.17 g/t gold, containing 859,500 ounces, a 229% increase from the PEA published in March 2025. Inferred resources fell 38% to 0.89 million tonnes at 7.06 g/t gold (202,800 ounces) as infill drilling converted material into higher-confidence categories. The estimate incorporates roughly 36,470 meters of drilling from 164 core holes completed between 2023 and the end of 2025.
