SIERRA METALS REPORTS SECOND QUARTER 2017 PRODUCTION RESULTS

SIERRA METALS REPORTS SECOND QUARTER 2017 PRODUCTION RESULTS

Toronto, ON – July 17, 2017Sierra Metals Inc. (TSX: SMT) (NYSE MKT: SMTS) (BVL: SMT) (“Sierra Metals” or “the Company” - http://www.commodity-tv.net/c/search_adv/?v=297652) is pleased to report second quarter 2017 production results featuring the second highest quarter of throughput and third highest quarter of metal production to date from the Yauricocha Mine.

Results are from Sierra Metals’ three underground mines in Latin America: the Yauricocha polymetallic Mine in Peru and the Bolivar copper and Cusi silver Mines in Mexico.

 

Second Quarter 2017 Production Highlights

 

  • Silver equivalent production of 2.7 million ounces; a 3% decrease from Q2 2016
  • Copper equivalent production of 23.1 million pounds; a 3% decrease from Q2 2016
  • Total tonnes processed of 454,805; a 10% decrease from Q2 2016
  • Increase of 14% in silver equivalent production and 10% increase in throughput at Yauricocha during Q2 2017 vs Q2 2016

 

During the second quarter of 2017, consolidated metal production decreased 3% compared to Q2 2016. The decrease in metal production was due to lower throughput, lower head grades and lower recoveries of all metals, except gold recoveries at Bolivar; and lower throughput, lead and zinc head grades, and silver and lead recoveries at Cusi. This was partially offset by higher throughput, higher copper and zinc head grades, and higher recoveries of all metals, except gold, at Yauricocha.

 

Igor Gonzales, President and CEO of Sierra Metals commented “Sierra Metals continues to see solid metals production and tonnage processed at our flagship Yauricocha Mine. We are working to increase tonnage at Bolivar with the procurement of new equipment and through the exploration and development of higher grade ore sources which are expected to come into the mine plan early next year.”

 

He continued, “At Cusi, weaker production was the result of a new plan which refocuses efforts away from narrow veins and emphasizes the access, development and production from the Santa Rosa de Lima zone, which has wider structures as well as higher silver grades. An initial 15,000 meter drill program recently completed saw average silver equivalent grades of 371 grams per tonne and average widths of 4.1 meters. The Company has almost completed an additional 15,000 meters of infill drilling and is working to complete a ramp designed to allow us to include material from the Santa Rosa de Lima zone, which has improved head grades as part of our mill feed in the latter part of the year. Additionally, structural development will be completed using a long hole mining method which is a change from our existing cut and fill methodology.”

 

He concluded “We continue working at all our mines to improve grade, operations and best practices as well as introduce modern equipment. Management are optimistic that these changes will serve to increase production and improve grade for the latter part of 2017 and for the years to come.”

 

 

 

 

Consolidated Production Results

 

 

 

Yauricocha Mine, Peru

 

The Yauricocha Mine processed the second highest quarterly throughput in the mine’s history of 237,912 tonnes in Q2 2017, representing a 10% increase compared to Q2 2016. The 14% increase in metal production in Q2 2017 was driven by higher plant throughput, higher copper and zinc head grades, and higher recoveries of all metals, except gold. The Company continues to see improvements in metal production as a result of the installation of a higher capacity hoist and the positive exploration and infill drilling results achieved during the last twelve months.

 

Continued production from higher grade ore zones, including the Esperanza Zone and the Cuerpos Chicos, has allowed the Company to continue to increase throughput and improve head grades, resulting in higher silver and copper equivalent metal production. The Company also saw an increase in the production of copper (77%) and zinc (18%), while production of silver, lead and gold decreased due to more copper oxides and no lead oxides being processed during Q1 2017. Management believes throughput and metal production will remain stable throughout the year.

 

A summary of production from the Yauricocha Mine for Q2 2017 has been provided below:

 

 

 

 

Bolivar Mine, Mexico

 

Bolivar saw a reduction in throughput during the quarter with 192,937 tonnes processed which was an 18% decrease when compared to Q2 2016. The lower throughput was due to lower head grades and recoveries which have been slightly lower due to higher antimony levels which have required some blending with lower grade ore stopes.  Additionally, lower volume occurred due to reduced equipment availability as well as the lack of water available to be pumped from the dam into the plant due to lower rainfall levels and an unusually dry summer season.  

 

Copper production of 3.1 million pounds decreased 27%, silver production of 73,000 ounces decreased 31% and gold production of 620 ounces decreased 17% in Q2 2017 compared to Q2 2016.

 

The Company’s focus at Bolivar during the remainder of 2017 will be on improving production volume through the procurement of new equipment including Jumbos, Scoops and Trucks which arrived near the end of the quarter, with the intention of moving more material from available production stopes within the mine.

 

A summary of production for the Bolivar Mine for Q2 2017 has been provided below:

 

 

 

Cusi Mine, Mexico

 

Total ore processed of 23,956 tonnes during Q2 2017 decreased 54% compared to Q2 2016. Lower head grades and recoveries for all metals contributed to the 54% decrease in silver equivalent production.

 

Silver production of 95,000 ounces decreased 55%, gold production of 126 ounces decreased 42%, lead production of 0.5 million pounds decreased 59%, and zinc production of 0.3 million pounds decreased 49% compared to Q2 2016.

 

Despite the decreases in tonnage and metal production at Cusi it is important to note that Cusi only represents approximately 5% of Sierra Metals current total production. Cusi’s contribution to the Company’s overall production is expected to increase depending on the exploration and development success expected at the recently discovered Santa Rosa de Lima zone.  The Company is currently re-evaluating its development plan at the mine following a successful reinterpretation of the mine’s geology. Management are very encouraged by data from a recently completed 15,000-metre drilling program (see press release dated June 5, 2017) that was focused on the high-grade Santa Rosa de Lima zone with a goal of increasing tonnage and grade at Cusi, which was not included in the recently released Mineral Resource Estimate at Cusi (please see news release dated April 13, 2017). Further drilling in this area is based on a new conceptual interpretation of the Santa Rosa de Lima structure at the Cusi Mine. This interpretation is based on exploration drilling of the NW-SE regional structural system and demonstrates that mineralization is consistent across the assessed area.

 

Management plans to focus on improving head grades and maintaining production at a rate of approximately 400 tpd, while stockpiling ore at the plant and producing it in batches. The Company is ramping down to the Santa Rosa de Lima zone in an effort to improve head grades as well as focus on the reinterpretation of geology at Cusi.
