Mine Operations

Dia Bras achieved record production results for the first quarter of 2012. The acquisition of Sociedad Minera Corona S.A. ("Corona") in May 2011 was the main driver of the substantial year-over-year increases in metal production. The Company achieved a total of 286,022 tonnes of ore processed from all operations representing an 827% increase year-over-year. These substantial increase in processing resulted in record quarterly production figures. 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 211,937 tonnes processed in the first 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 first quarter of 2012, aggregate production of these ore bodies was 496 Koz of Ag, 2.6 million lb of Cu, 7.8 million lb of Pb, 10.5 million lb of Zn and 2,995 oz of Au. A summary of production from the Yauricocha Mine for the first quarter of 2012 has been provided below.

Currently, the Company is completing an updated NI 43-101 resource calculation and anticipates releasing it in the second quarter of 2012.

Bolivar Mine, Mexico

With the announcement of commercial production November 29, 2011, first quarter of 2012 was the first full quarter of production since completion of the new Piedras Verdes Mill. During this period total ore processed at the Bolivar Mine increased 154% with 61,949 tonnes compared to 25,980 tonnes in the first quarter of 2011. As a result, production of silver increased 101% year-over-year with a total of 44 Koz (22 Koz in 2011) and total copper production increased 122% year-over-year with 1.2 million lb produced (0.6 million lb in 2011). Despite the substantial increase in throughput during the first quarter of 2012, zinc production decreased 12% year-over-year to 3.1 million lb (compared to 3.6 million lb in 2011) as a result of a lower head grade of 2.9% compared to 7.1% in the first quarter of 2011. A summary of production from the Bolivar Mine for the first quarter of 2012 has been provided below.

The Company continues to realize operating efficiencies at the Bolivar Mine and in March of 2011 achieved its highest monthly throughput with 25,038 tonnes per month processed. Currently, the Company is completing an updated NI 43-101 resource calculation and anticipates releasing it by the end of the second quarter this year.

Cusi, Mexico

During the first quarter of 2012 the Cusi Pilot-Mining operation processed 12,136 tonnes through flotation and 7,553 tonnes through lixiviation compared to 4,887 tonnes and 6,821 tonnes, respectively, during the same period in 2011. This substantial increase in tonnes processed was planned to offset projected decreases in head-grades for silver and lead. During the first quarter of 2012 head grades for silver and lead were 156 g/t Ag (compared to 277 g/t Ag in the same period of 2011) and 0.52% Pb (compared to 1.78% in in the same period of 2011). A summary of production from Cusi's Pilot-Mining Operations for the first quarter of 2012 has been provided below.

Currently, the Company is in the midst of a substantial exploration programme on the Cusi property that will focus on expanding known zones of disseminated-type silver mineralization in the vicinity of the Promontorio and Santa Eudwiges deposits. Additionally, on a more regional scale, exploration work will focus on defining the continuity of this high-grade, disseminated-type silver mineralization along the Cusi Fault that spans some 3 kilometers between the Promontorio and Santa Eduwiges. The Company anticipates completing an updated NI 43-101 resource calculation on the property in the fourth quarter of 2012.
