Company Overview

Osisko Development Corp. is a North America–focused gold development company engaged in the acquisition, exploration, development, and potential production of precious metal assets. The company operates within the gold mining and development industry, with its business centered on advancing past-producing or historically explored mining districts toward production. Its primary value proposition is the redevelopment of high-quality, district-scale assets in stable mining jurisdictions.

The company’s core revenue drivers are expected to come from future gold production rather than current operating cash flow, as Osisko Development remains primarily in the development and construction phase. Its strategic positioning emphasizes assets with existing infrastructure, historical production, and defined mineral resources, which management believes can reduce development risk. Osisko Development was formed in 2020 through a strategic reorganization by Osisko Gold Royalties Ltd., evolving into an independent public company focused on mine development rather than royalty generation.

Business Operations

Osisko Development’s operations are organized around three principal development-stage assets: the Cariboo Gold Project in British Columbia, the Tintic Project in Utah, and the San Antonio Gold Project in Mexico. These assets collectively represent the company’s core business units and are intended to support a phased transition from development to production. The company does not currently report sustained commercial production, and revenue generation is primarily tied to financing activities rather than mineral sales.

Operationally, the company controls mineral rights, processing facilities under development, historical underground workings, and land packages associated with its projects. The Cariboo Gold Project is the most advanced asset, supported by feasibility studies and permitted infrastructure. Osisko Development operates through wholly owned subsidiaries and does not rely on material joint ventures for its core assets, though it maintains technical and contractor relationships typical of mine development companies.

Strategic Position & Investments

Osisko Development’s strategic direction is focused on advancing its flagship Cariboo Gold Project toward near-term production while incrementally de-risking its U.S. and Mexican assets through exploration and engineering studies. Growth initiatives include continued underground development, resource expansion drilling, and optimization of mine plans to improve project economics. Capital investments are primarily allocated toward construction readiness, permitting, and exploration programs.

The company’s asset portfolio reflects targeted acquisitions of advanced-stage projects rather than grassroots exploration. The acquisition of the Tintic Project expanded its presence in the United States and added a high-grade historic mining district to its portfolio. Osisko Development maintains a strategic relationship with Osisko Gold Royalties Ltd., which has participated as an investor and financing partner, providing balance sheet support and industry alignment rather than operational control.

Geographic Footprint

Osisko Development operates exclusively in North America, with a geographic footprint spanning Canada, the United States, and Mexico. Its corporate headquarters are located in Montreal, Quebec, while its principal operational focus is in Western Canada and the Western United States. The company’s assets are located in established mining regions with existing infrastructure and regulatory frameworks supportive of mineral development.

The Cariboo Gold Project anchors the company’s presence in British Columbia, representing its most significant capital commitment. In the United States, the Tintic Project provides exposure to Utah, a jurisdiction with a long mining history. The San Antonio Gold Project extends the company’s reach into Mexico, offering geographic diversification while maintaining a focus on politically stable and mining-friendly regions.

Leadership & Governance

Osisko Development is led by a management team with extensive experience in mine development, capital markets, and royalty-based mining finance. The company benefits from continuity with the broader Osisko group, reflecting a governance philosophy centered on disciplined capital allocation, technical rigor, and long-term asset value creation.

Key executives include:

• Sean Roosen – Chairman & Chief Executive Officer
• Matthew Gili – Chief Financial Officer
• Guy Gagnon – President
