Osisko Development Business Summary

Osisko Development Corp. (ODV) is a North American gold development company that generates revenue through the extraction and sale of precious metals, primarily from its high-grade Trixie mine at the Tintic Project. The company’s business model focuses on the rapid advancement of past-producing mining camps in tier-one jurisdictions, with primary business segments comprising the flagship Cariboo Gold Project in British Columbia and the Tintic Project in Utah. Following the January 2026 divestiture of its San Antonio asset in Mexico, Osisko has streamlined its portfolio to accelerate its transition into an intermediate producer targeting over 200,000 ounces of annual gold production. Key direct competitors include Perpetua Resources, Centerra Gold, and Endeavour Silver, against whom Osisko differentiates itself through its fully permitted status at Cariboo and a robust resource-to-reserve conversion strategy backed by extensive historical data. The leadership team is anchored by Founder, Executive Chairman, and CEO Sean Roosen, whose pedigree includes co-founding the original Osisko Mining and developing the Canadian Malartic mine, one of Canada’s largest gold operations. He is supported by President Chris Lodder, a veteran explorer with a track record of discovering over 34 million ounces of gold, and CFO Alexander Dann, who manages the firm’s complex multinational financial operations. Recent strategic appointments include Sarah Harrison as VP of Permitting and Compliance (February 2026) and David Rouleau as VP of Project Development, who oversees operational readiness for the Cariboo build-out. The company maintains strong institutional backing, most notably from Appian Capital Advisory, which secured a US$450 million project loan facility in late 2025 to fully fund the flagship project's construction phase.
