Notable Quotes

• Gerald Panneton, Chairman and CEO: "The PEA study is the major step towards bringing the project towards possible development and potential future production. The PEA is to be based on the recent May 15, 2026 press release announcement on adding 595,000 Inferred ounces within 5.1 million tonnes grading 3.64 g/t gold on the 103N zone, and the updated mineral resource study due in September 2026, with the addition of almost 20,000 metres of drilling unaccounted for. After spending nearly C$ 19 million in drilling, we look forward to the potential restart of the historic Con Mine once the purchase is completed (see news release November 22, 2021)."
