Production Guidance for 2015

Silver: 3,144,000 oz – 3,668,000 oz
Copper: 21.0 million lb – 24.3 million lb
Lead: 44.3 million lb – 51.8 million lb
Zinc: 41.9 million lb – 48.9 million lb
Gold: 11,200 oz – 13,000 oz

Audra Walsh, President and CEO of Sierra Metals, commented:“2014 was another record year of metal production driven by organic growth in our three mines. The Company’s metal production exceeded the high end of the guidance for silver, gold, lead and zinc while copper production was within the guidance range. Our Q4 2014 production of 875,400 silver ounces was the highest quarter in the history of the Company, as was the ore throughput. The management team remains focused on executing opportunities to further increase production and reduce costs in 2015, which we anticipate will help offset the impact of depressed metal prices. The quality of our assets will enable us to continue delivering solid production results during 2015.”

Mine Operations

The total tonnes of ore processed of 1,706,715 in 2014 compared to 1,321,781 in 2013 was a 29% increase year-over-year. The success of increasing consolidated metal production in 2014 was assisted by higher throughput at all three mines, Bolivar (76%), Cusi (45%) and Yauricocha (6%).

A summarized table of our Q4 2014 consolidated production results is presented below:

Consolidated Production 3 Months Ended 12 Months Ended
Dec 31, 2014 Dec 31, 2013 % Var Dec 31, 2014 Dec 31, 2013 % Var

Yauricocha Mine, Peru

The Yauricocha Mine continued to be the Company’s largest producing mine with a total of 224,986 tonnes processed in Q4 2014 representing a 5% increase compared to 214,454 tonnes in Q4 2013. Total annual tonnes processed of 885,495 in 2014 compared to 837,496 tonnes in 2013 resulted in a 6% increase year-over-year. Mineralization at the Yauricocha Mine is hosted in three different zones including Lead-Oxide, Copper-Oxide and Polymetallic ore-bodies.

During Q4 2014, aggregate production of these ore bodies was 595,340 oz of silver, a 28% increase year-over year; 2.3 million lb of copper, a 97% increase year-over-year; 11.6 million lb of lead, a 6% increase year-over year; 13.4 million lbs of zinc, consistent year-over year; and 1,360 oz of gold, an 18% decrease year-over-year. Higher metal production was mainly driven by an increase in the polymetallic and copper oxide throughput and by higher lead and copper head grades, and higher silver and lead recoveries. Increase in production was partially offset by lower head grades in the Lead-Oxide body in line with Yauricocha’s mine plan. A summary of production from the Yauricocha Mine for Q4 2014 has been provided below:
