Press Release Highlights:

• Total silver ("Ag") production of 728,211 ounces ("oz") in the first quarter of 2014 compared to 610,407 oz for the same period of 2013. A 19% increase year-over-year.
• Total copper ("Cu") production of 5.7 million pounds ("lb") in the first quarter of 2014 compared to 4.1 million lb for the same period of 2013. A 41% increase year-over-year.
• Total lead ("Pb") production of 12.2 million lb in the first quarter of 2014 compared to 8.5 million lb for the same period of 2013. A 43% increase year-over-year.
• Total zinc ("Zn") production of 12.7 million lb in the first quarter of 2014 compared to 13.3 million lb for the same period of 2013. A 4% decrease year-over-year.

Daniel Tellechea, President and CEO of Sierra Metals, commented: "Sierra's strong production during the first quarter is mainly reflective of higher lead head grades and silver recoveries at Yauricocha, and higher throughputs at the Bolivar and Cusi mines. Bolivar has been operating at a rate close to 2,000 tpd during the quarter and Cusi at an average production rate of 375 tpd. We expect solid production results in the second quarter and we are on target to meet our production guidance for 2014."

Mine Operations

During this period, the Company achieved a total of 416,465 tonnes of ore processed (compared to 317,637 tonnes in 2013) from all operations, representing a 19% increase year-over-year.

There was no variation in production at the Yauricocha Mine during the first quarter of 2014 versus the first quarter of 2013, while production increased 126% at Bolivar and 16% at Cusi. The lower grade in silver and copper at Yauricocha and Bolivar was completely offset by the following strong production results: (1) higher production rates at Bolivar, (2) higher lead head grades and silver recoveries at Yauricocha, and (3) overall higher production rates, grades and recoveries at Cusi. A summarized table of consolidated production results is presented below:

Yauricocha Mine, Peru

The Yauricocha Mine continued to be the Company's largest producing mine with a total of 215,550 tonnes processed in the first quarter of 2014, representing no variation compared to 214,867 tonnes in 2013. Mineralization at the Yauricocha Mine is hosted in two different zones including Lead-Oxide ("Oxides") and Polymetallic orebodies.

During the first quarter of 2014, aggregate production of these orebodies was 494,294 oz of silver, a 4% increase year-over year; 1.7 million lb of copper, a 20% decrease year-over-year; 11.7 million lb of lead, a 39% increase year-over year; 12.7 million lb of zinc, a 2% decrease year-over year; and 1,474 oz of gold, a 8% decrease year-over-year. Lower copper production was driven by lower head grades in line with Yauricocha's mine plan. A summary of production from the Yauricocha Mine for the first quarter of 2014 has been provided below:

Silver production at Bolivar increased 70% year-over-year with a total of 91,660 oz produced (compared to 54,062 oz in 2013).

Cusi Mine, México

On January 1, 2013 the Company announced that the Cusi Mine achieved commercial production but is still under development as most of the ore comes from development rock. During the first quarter of 2014, total ore processed increased 16% with a total of 32,825 tonnes of ore processed (compared to 28,315 tonnes in 2013). During the first quarter of 2014, production of silver at Cusi increased 74% with a total of 142,258 oz of silver (compared to 81,744 oz in 2013). This increase is mainly driven by higher throughput compared to the first quarter of 2013 (32,825 tonnes versus 28,315 tonnes), higher head grades and recoveries compared to the first quarter of 2013 (169.3 g/t Ag versus 141.7 g/t Ag), higher recoveries (79.6% versus 63.4% in the first quarter of 2013).
