We are a premier Latin American precious and base metals producer with significant resource growth potential. The Company owns and operates three mines in commercial production: the Yauricocha Mine in Peru, the Bolivar and Cusi mines 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 Bolivar Mine property was acquired and active development was done to advance the property towards production. In 2006, a rapid expansion into the Cusihuiriachic (“Cusi”) silver district resulted in the acquisition of a 100 km2 property encompassing 12 former silver mines. From 2006 to 2011 the Company shipped high-grade development ore from the Bolivar project to its wholly owned Malpaso Mill. Starting in 2009, the Company started producing silver dore at the Malpaso Mill from development ore at the Cusi project.
