Bolivar Mine, Mexico

Since the announcement of commercial production on November 29, 2011, the new Piedras Verdes mill has continued to increase the production profile of the Bolivar Mine. During the third quarter of 2012, total ore processed at the Bolivar Mine increased 110% with 71,239 tonnes processed compared to 33,859 tonnes in the same period of 2011. This resulted in third quarter production of copper increasing 82% year-over-year for a total of 1.5 million lb, compared to 0.8 million lb in 2011. Despite this substantial increase in throughput during the third quarter of 2012, zinc production decreased 71% year-over-year to 1.3 million lb compared to 4.4 million lb in 2011. The decrease in zinc production resulted from a lower head-grade of 1.21% in the third quarter of 2012 compared to 6.65% in the same period in 2011. Additionally, silver production decreased by 2.3% in the third quarter of 2012 to 39,239 oz compared to 40,145 oz in the same period of 2011. This decrease in production was the result of a 53% decline in head grade from 46 g/t Ag in 2011 compared to 22 g/t Ag in 2012. A summary of production from the Bolivar Mine for the third quarter of 2012 has been provided below.

Cusi, Mexico

Total production at Cusi increased 170% in the third quarter of 2012 with 25,084 tonnes processed compared to 9,270 tonnes in the same period in 2011. The higher tonnage is explained by the additional processing of 11,965 tonnes of historic tailings at the Mal Paso plant while Cusi's mineral accounted for 13,120 tonnes. In this context, the combined effect of historic tailings and Cusi's mineral during the third quarter of 2012 drove silver and lead grades down to 158 g/t and 0.56%, compared to 181 g/t and 0.62% in the same period of 2011, respectively. A summary of production from the Cusi operation for the third quarter of 2012 has been provided below.
