Nyrstar

Overview

The G9 project is located in Guerrero State, Mexico. The area comprises 12,000 hectares in six mining concessions that are some 160 kilometres south-southwest of Mexico City. The mineral deposit currently being mined is the G9 deposit, which achieved commercial production in April 2009 and comprises high grade zinc, copper, lead, gold and silver. In addition to the G9 Mine, there are four additional ore bodies that have been delineated as JORC compliant resources (Reforma, El Largo, El Rey and Naranjo). In January 2011, Nyrstar successfully completed the acquisition of Farallon Minera Mexicana S.A. de C.V. (Farallon).
