The Bolivar mine is a low cost copper-zinc-silver producing asset that achieved commercial production in November 2011. The Company completed an updated NI 43-101 compliant resource in the fall of 2012 and has expanded the Piedras Verde mill to 2,000 tpd in the fall of 2013
The Company also owns a substantial base of advanced exploration properties in Chihuahua, Mexico.

Commercial production at Cusi was declared in January 2013. Development ore from Cusi is currently being processed at the Malpaso Mill to generate revenues and advance the property towards becoming an important silver producing mine. A NI 43-101 was completed in July 2013 and an aggressive exploration and development programme resulted in a resource update in late March 2014.
