Mine Operations

Dia Brasachieved record-breaking production in the second quarter of 2012. The acquisition of Sociedad Minera Corona S.A. ("Corona") inMay 2011, coupled with the announcement of commercial production at the Bolivar Mine were the two main drivers of the substantial year-over-year increases in metal production. The Company reached a total of 323,396 tonnes of ore processed (compared to 37,408 in 2011) from all operations, representing a 765% increase year-over-year. These substantial increases in production have resulted in record production figures in the second quarter and the first half of 2012. A summarized table of consolidated production results is presented below.

Yauricocha Mine, Peru

The Yauricocha Mine inPerucontinued to be the Company's largest producing mine with a total of 217,078 tonnes processed in the second 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 second quarter of 2012, aggregate production of these ore bodies was 544,707 oz of Ag, 2.2 million lb of Cu, 9.0 million lb of Pb, 11.5 million lb of Zn and 2,876 oz of Au. A comparative summary of production from the Yauricocha Mine for the first and second quarters of 2012 has been provided below.

Bolivar Mine, Mexico

Since the announcement of commercial production onNovember 29, 2011, at the Bolivar Mine, the new Piedras Verdes mill has continued to consistently increase production throughput. During the second quarter of 2012, total ore processed at the Bolivar Mine increased 203% with 86,061 tonnes processed compared to 28,415 tonnes in the same period of 2011. This substantial increase resulted in second quarter production of silver increasing 52% year-over-year for a total of 52,544 oz, compared to 34,585 oz in 2011; and copper production increasing 135% year-over-year with 1.9 million lb produced compared to 0.8 million lb in 2011. Despite this substantial increase in throughput during the second quarter of 2012, zinc production decreased 13% year-over-year to 3.8 million lb compared to 4.4 million lb in 2011. The decrease in zinc production resulted from a lower head-grade of 2.51% in the second quarter of 2012 compared to 7.94% in the same period in 2011.
