Sierra Metals Inc. said its full-year production came in ahead of guidance in the majority of metal groups. The company plans to boost production of silver and gold in 2015, is targeting largely unchanged production in copper and lead, and a drop-off in the production of zinc. "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,” said president and chief executive officer Audra Walsh. “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."
