Cordero Permitting Milestone Within Discovery's Broader Growth Strategy

Beyond Cordero, the company's disclosure notes that Discovery is advancing plans to more than double annual gold production through its Porcupine assets near Timmins, Ontario. The acquisition of the Kidd Operations in June 2026 is cited as expanding the company's land position and adding critical minerals to its production profile.
