Performance overview

sierra metals inc. is a premier latin american precious and base metals producer. the company owns and operates three mines in commercial production: the yauricocha mine in peru, the bolivar and cusi mines in mexico. in the spring of 2011, sierra metals expanded operations into peru with the acquisition of 82% of sociedad minera corona s.a. (“corona”) . corona’s main asset is the yauricocha mine in the yauyos province in western central peru. this purchase dramatically transformed the production profile of sierra metals and propelled 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 had originally a throughput capacity of 1,000 tpd and after the 2013 expansion, the capacity now stands at 2,000 tpd. in janu
