It said the Hurricane Project benefits from "excellent" infrastructure, located approximately 40 km northwest of the McClean Lake mill, and features relatively shallow mineralization at near 325 m, "supporting efficient exploration and future development optionality".

Dan Brisbin, vice president of exploration, said, "Planned drilling is expected to build on positive 2025 results and continue our approach of both testing deposit expansion targets around the margins of the Hurricane deposit and exploring for new deposits along the highly prospective Larocque Trend."
