Sierra Metals is a leading producer of precious and base metals in Latin America. The company owns and operates three commercially producing mines: Yauricocha in Peru, and Bolivar and Cusi in Mexico.Sierra Metals, formerly Dia Bras Exploration, began exploration and development work in Mexico in early 2003. In 2004, the Bolivar mine was acquired and aggressively developed to move the mine towards production. In 2006, the Cusihuiriachic ("Cusi") silver district expanded rapidly with the acquisition of a 100-square-kilometer property that included 12 former silver mines. From 2006 to 2011, the company shipped high-grade development ore from the Bolivar project to its wholly-owned Malpaso plant. Beginning in 2009, the company started producing silver doré at the Malpaso mill from development ore at the Cusi project.Sierra Metals is committed to expanding its global reserves and resources in Peru and Mexico. Currently, extensive exploration and development programs are underway to increase known reserves and resources near each mine. Additionally, broader regional targets are being explored to continue advancing the company’s project pipeline towards production.Sierra Metals continues to strive toward its goal of becoming a leading low-cost producer of precious and base metals in Latin America by enhancing its production profile and continually increasing its reserves and resources.
