Sierra Metals Reports 2015 Production and Announces 2016 Production Outlook

• INCREASE IN PRODUCTION OF 32% AT ITS BOLIVAR MINE AND 18% AT ITS CUSI MINE OFFSET BY TEMPORARY DECLINE of 14% AT ITS YAURICOCHA MINE IN THE FOURTH QUARTER 2015

TORONTO, Feb. 9, 2016 /CNW/ - Sierra Metals Inc. (TSX: SMT) (BVL: SMT) ("Sierra Metals" or "the Company") reports fourth quarter production results including an increase in copper equivalent production and record throughput at its Bolivar Mine, and an increase in silver equivalent production at its Cusi Mine, while the restructuring process at its Yauricocha Mine continued to temporarily depress throughput and grades resulting in lower production for the three-month period ended December 31, 2015 ("Q4 2015").

Total consolidated tonnes processed increased by 9%, however silver equivalent and copper equivalent production both decreased by 7% respectively for the twelve-month period. Results are from Sierra Metal's three underground mines in Latin America: the Yauricocha polymetallic Mine in Peru and the Bolivar copper and Cusi silver Mines in Mexico.

Fourth Quarter Production Highlights

• Total tonnes processed of 456,842; a 7% increase over Q4 2014
• Silver equivalent production of 2.3 million ounces; a 23% decrease from Q4 2014
• Copper equivalent production of 15.6 million pounds; a 23% decrease from Q4 2014

Fourth Quarter consolidated metal production declined as a result of reduced plant throughput of 14% and lower ore grades at the Yauricocha Mine in Peru which was partially offset by the increase in throughput at both the Bolivar and Cusi Mines. The decrease in throughput at the Yauricocha Mine continues to be attributable to the ongoing restructuring that has addressed the management of water control issues, and is focused on the improvement of mine sequencing and implementation of best practices and mechanization of the Mine.

"While we anticipate improved consolidated results in the current year, we are extremely pleased to see increased copper equivalent production at Bolivar and growth in silver equivalent production at Cusi." commented Mark Brennan, President and CEO of Sierra Metals.  "We continue to focus on the restructuring and rehabilitation at the Yauricocha Mine with the implementation of best practices and the introduction of modern methodologies. Management is optimistic that these beneficial changes that have resulted in lower production in the near term will serve to increase production in the coming years."

He continued, "Further success in brownfields exploration such as the recent discovery of the Esperanza Zone at our Yauricocha Mine, combined with our production optimization program shall enable Sierra Metals to continue on a solid path of increased production and resource growth for the foreseeable future."  

Production Guidance for 2016

The company is pleased to announce consolidated production guidance for 2016.

	2016 Guidance
	Low	High
Silver ounces	2,600,000	3,200,000
Copper pounds (000's)	24,400	30,100
Lead pounds (000's)	26,700	32,900
Zinc pounds (000's)	43,200	53,400
Gold ounces	9,100	11,200
Silver equivalent ounces (000's)^(1)	10,400	12,800
Copper equivalent pounds (000's)^(1)	69,100	85,300

(1) 2016 Silver equivalent ounces & copper equivalent pounds were calculated using the following metal prices: $14.96/oz Ag, $2.25/lb Cu, $0.75/lb Pb, $0.73/lb Zn, $1,112/oz Au.

All metals have a higher production guidance for 2016 than compared to 2015 production with the exception of lead.  Production of lead at the Yauricocha Mine is forecasted to be lower due to required stope development which has yet to be completed as well as anticipated lower grades at depth in the central mine zone. Replacement of Higher grade lead zones are expected to come from the recently discovered Esperanza zone in the future.

Yauricocha Mine, Peru

The Yauricocha Mine processed a total of 193,710 tonnes in Q4 2015 representing a 14% decrease compared to Q4 2014.

Lower metal production was driven by lower plant throughput and lower head grades from the polymetallic and lead-oxide concentrates.

Lower recoveries of lead and silver were a consequence of lower head grades in the ore sources available to be mined in 2015 versus 2014.
