Osisko Development Corp. is a North American gold development company focused on past-producing camps located in mining friendly jurisdictions with district scale potential. Spearheaded by Sean Roosen—who discovered, funded, built and operated Canada’s largest gold producing mine, Canadian Malartic—the Company’s objective is to become an intermediate gold producer. Its flagship fully permitted 100%-owned Cariboo Gold Project, located in B.C., Canada, received its permits in Q4 2024 with project finance discussions already underway. Meaning, Osisko is one of the few developers with a shovel ready project in North America. The Company also boasts considerable brownfield exploration potential at its two other properties—the Tintic Project in the historic East Tintic mining district in Utah, U.S.A., and the San Antonio Gold Project in Sonora, Mexico.
