Mine Operations

Sierra Metals maintained strong production results in the second quarter of 2013. During this period, the Company achieved a total of 323,751 tonnes of ore processed (compared to 325,913 tonnes in 2012) from all operations, representing a 1% decrease year-over-year.

Despite a decrease in production at the Yauricocha Mine, the Company maintained strong production in the quarter resulting from (1) the Cusi Mine achieving commercial production as of January 1, 2013, and (2) continued increases in operating efficiencies at the Bolivar Mine. Both of these achievements are part of the Company's growth strategy to expand production in Mexico during 2013. A summarized table of consolidated production results is presented below.

Bolivar Mine, Mexico

During the second quarter of 2013, total ore processed at the Bolivar Mine increased 3% with 88,406 tonnes processed compared to 86,061 tonnes in 2012. Silver production at Bolivar increased 41% year-over-year with a total of 74,037 oz produced (compared to 52,544 in 2012). This substantial increase in production was a result of higher silver-grades (30.33 g/t Ag in 2013 compared to 24.38 g/t Ag in 2012) and an increase in recovery rates (85.58% recovery in 2013 compared to 77.74% in 2012) year-over-year. Copper production during the period increased 7% with a total of 2.0 million lb produced (compared to 1.9 million lb in 2012). Zinc production decreased 83% with a total of 0.7 million lb produced (compared to 3.8 million lb in 2012). The decline in Zinc production resulted from a decrease in Zinc grades (0.75% in 2013 compared to 2.51% in 2012) and reduced recovery rates (44.92% in 2013 compared to 80.12% in 2012).
