Founded in the mid-1990s as a junior exploration outfit, Sierra Metals has grown through disciplined project evaluation, strategic acquisitions and focused capital investment. The company is headquartered in Vancouver, Canada, and maintains a technical and administrative staff that supports operations across North and South America. Sierra Metals places strong emphasis on sustainable practices, safety protocols and community engagement, integrating environmental stewardship into its mine development plans.
Leadership at Sierra Metals is led by President and CEO Mario Stifano, whose tenure has emphasized operational optimization and cost control. The board and management team bring extensive experience in mining engineering, finance and corporate governance. Looking ahead, the company continues to advance exploration initiatives near existing operations and evaluate additional prospects to expand its resource base and production profile.
