Dia Bras continues to achieve record production results in the third quarter of 2012

Dia Bras achieved record-breaking production in the third quarter of 2012. The announcement of commercial production at the Bolivar Mine coupled with improvements in operating efficiencies resulted in year-over-year increase of total metal production. The Company achieved a total of 317,355 tonnes of ore processed (compared to 251,526 tonnes in 2011) from all operations, representing a 26% increase year-over-year. A summarized table of consolidated production results is presented below.

Yauricocha Mine, Peru

The Yauricocha Mine in Peru continued to be the Company's largest producing mine with a total of 221,033 tonnes processed in the third quarter of 2012. Mineralization at the Yauricocha Mine is hosted in three different zones including the Copper, Lead-Oxide ("Oxides") and Polymetallic ore bodies.

During the third quarter of 2012, aggregate production of these ore bodies was 559,719 oz of Ag, 2.0 million lb of Cu, 9.8 million lb of Pb, 14.1 million lb of Zn and 2,409 oz of Au. A summary of production from the Yauricocha Mine for the third quarter of 2012 has been provided below.

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.

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.
