Sierra Metals Inc. is a growing mid-tier precious and base metals producer in Latin America. The Company owns two low-cost mines in commercial production: the Yauricocha mine in Peru and the Bolivar mine in Mexico.
Sierra Metals Inc., formerly known as Dia Bras Exploration Inc., began exploration and development work in Mexico in early 2003. In 2004, the Company acquired the Bolivar mine property and began active development to advance the property towards production. In 2006, a rapid expansion into the Cusihuiriachic (“Cusi”) silver district resulted in the Company acquiring a 100 km2 property encompassing 12 former silver mines situated within a close proximity to the wholly owned Malpaso Mill. From 2006 to 2011 the Company shipped high-grade development ore for custom milling to the Malpasso Mill from the Bolivar project. Starting in 2009 the Company also started producing silver dore at the Malpaso Mill from development ore at the Cusi project.
In the spring of 2011, the Company expanded operations into Peru with the purchase of 82% of Sociedad Minera Corona S.A. (“Corona”) for a total purchase price of $286 million. Corona’s main asset is the Yauricocha mine in the Yauyos province in western central Peru. This purchase dramatically changed the production profile of Sierra Metals and excelled the Company from a junior exploration and development company to a mid-tier precious and base metals producer.
This rapid expansion in Peru was followed by the completion of the Piedras Verdes mill in Mexico and the announcement of commercial production at the Bolivar mine. Located 6 km from the Bolivar mine, the Piedras Verdes mill has a throughput capacity of 1,000 tpd with plans to expand to 2,000 tpd by mid-2013.
Sierra Metals is currently focused on expanding production at its Yauricocha and Bolivar mines and advancing its Cusi Property into commercial production. Additionally, the Company is completing an aggressive exploration and development programme to expand global reserves and resources and advance its pipeline of projects towards to production.
