From Nov 2019 to Nov 2024
TORONTO, Jan. 24, 2019 /PRNewswire/ - Sierra Metals Inc. (TSX: SMT) (BVL: SMT) (NYSE AMERICAN: SMTS) ("Sierra Metals" or "the Company") is pleased to report fourth quarter 2018 and full year 2018 production results, as well as 2019 production guidance. 2019 cost and capital expenditure guidance will be provided in February as the planning and costing of various capital projects, which have been recently added or modified, are currently being completed.
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.
2018 Consolidated Production Highlights
Fourth Quarter 2018 Production Highlights
The Company achieved record consolidated quarterly ore throughput during Q4 2018, as well as record quarterly ore throughput from the Bolivar and Cusi Mines. These results continued the Company's successful production increases realized during the first three quarters of 2018, which resulted in strong annual consolidated production figures.
Metal production at Yauricocha increased 14% in Q4 2018 compared to Q4 2017 due to 5% higher ore throughput, higher head grades of all metals, except zinc, and higher lead and gold recoveries. At Bolivar, 20% higher ore throughput, and higher silver and gold head grades resulted in a 16% increase in copper equivalent pounds produced in Q4 2018 compared to Q4 2017. The Cusi Mine realized a 258% increase in throughput which resulted in a 70% increase in silver equivalent ounces produced during Q4 2018 compared to Q4 2017.
During 2018, the annual consolidated production of silver, copper, zinc and gold increased 17%, 27%, 1%, and 25%, respectively, while annual consolidated lead production decreased 7% compared to 2017.
Igor Gonzales, President and CEO of Sierra Metals, commented: "I am very pleased with the Company's strong Q4 production results, which contributed to a solid year of production in 2018. The Company continues to reap the benefits of the successful operational improvement programs at all Mines.
The Company has completed expansion work at the Bolivar Mine and is ramping up to 3,600 tonnes per day while also implementing a throughput expansion at Cusi to 1,200 tonnes per day. The Company has also completed all of the necessary work and has submitted all of the required documentation to the authorities in Peru for its Yauricocha mine and expects to receive its Environmental Impact Assessment permit shortly. Furthermore, the Company has almost completed updated Life of Mine Plans, and is working to complete Pre-Feasibility and Feasibility studies, based on the encouraging PEA's results released for all three Mines, demonstrating positive economics, and supporting the potential for future important production expansions.
At Yauricocha, during Q4 2018, we have completed the refurbishment of the lower part of the Mascota Shaft as well as the infrastructure and tie-ins for the Yauricocha tunnel, allowing for faster turn-around in the cycle time of the trolley locomotives, and providing for increased capacity and handling of larger volumes of ore and waste. Tonnage through the tunnel can be ramped up further as larger locomotives and ore cars are added in the future.
In Q1 2019 the Yauricocha shaft continues to be sunk to the 1270 level to provide access to further reserves and resources at the Mine and loading pockets will be added later this year on the 1210 level. Also, work will commence on a ramp connecting the 920 level with the 720 level at Yauricocha providing for an additional 10,000 tonnes per month of increased capacity to move ore and waste from the mine."
He concluded, "2019 will be an important year for the Company as we ramp up production in Mexico while continuing to modernize and improve all Mines implementing best operational practices. These changes should allow the Company to increase metal production to new highs. Our Company wide ongoing brownfield exploration programs should also lead to further significant growth in reserves and resources, which will add to the value of our assets during the year ahead."

Yauricocha Mine, Peru
The Yauricocha Mine processed a total of 1,106,649 tonnes during 2018, representing an 8% increase from 2017, and 268,363 tonnes in Q4 2018, representing a 5% increase compared to Q4 2017. Zinc equivalent metal production in Q4 2018 increased by 14% due to higher ore throughput, higher head grades for all metals, except zinc, and higher lead and copper recoveries. The higher lead head grades and lead production realized during Q4 2018 was the result of increased production from the cuerpos chicos that contained higher lead grades during the quarter. Higher copper head grades and lower zinc head grades resulted from the inclusion of certain copper-enriched zones at Esperanza, polymetallic ore from the Central Mine Zone, and a small inclusion of polymetallic ore from the cuerpos chicos.
Year over year zinc equivalent production was 7% higher in 2018 compared to the prior year. Copper Production was 43% higher, zinc production 2% higher, and gold production was 18% higher. This was partially offset by a 5% decrease in silver production, and a 5% decrease in lead production from 2017.

Bolivar Mine, Mexico
The Bolivar Mine processed 1,031,750 tonnes in 2018, representing a 16% increase over 2017. Q4 2018 record throughput was 272,645 tonnes, which was 20% higher when compared to Q4 2017. The higher throughput and higher gold and silver head grades resulted in a 16% increase in copper equivalent production in Q4 2018 compared to Q4 2017. The increase in throughput was due to the work performed to increase the profile of the ramps and main access drives to 5 meters wide x 5 meters high within the mine to provide access to larger conventional road dump trucks as well as articulating 6-wheel trucks to move higher volumes of ore out of the mine. The development work performed during the year resulted in increased access to more minable stopes which also contributed to the higher throughput. The Company is pleased with the progress made on the expansion plans at the Bolivar Mine. With the early completion of construction at the Piedras Verdes Mill, we expect to deliver on the goal of a 20% increase in production from 3,000 TPD to 3,600 TPD, in Q1 2019.
Copper equivalent production at the Bolivar Mine increased 16% in 2018 compared to 2017, with copper production 14% higher, silver production 38% higher, and gold production 38% higher. In Q4 2018, copper production increased by 8% to 4,230,000 pounds, silver production increased 53% to 128,000 ounces, and gold production increased 47% to 1,163 ounces compared to Q4 2017. The 16% increase in copper equivalent production was driven by higher throughput, and higher silver and gold head grades.

Cusi Mine, Mexico
Annual production at the Cusi Mine was 186,889 tonnes in 2018, which was 112% higher than 2017. Total ore processed increased 258% to 58,289 tonnes during Q4 2018 compared to Q4 2017. The higher throughput was partially offset by lower head grades and recoveries for all metals, but still resulted in a 70% increase in silver equivalent production in Q4 2018 compared to Q4 2017.
Silver equivalent production increased 48% during 2018 compared to 2017, as silver production increased 108% to 700,000 ounces, while gold production decreased 12% to 372 ounces, lead production decreased 33% to 1,194,000 pounds and zinc production decreased 92% to 71,000 pounds. However, during Q4 2018, silver, gold, and lead production were 107%, 62%, and 38% higher than Q4 2017, respectively.
The increase in throughput was partially the result of the Company's successful development and mining of ore from the recently discovered high-grade silver stockwork zone located within the Santa Rosa de Lima ("SRL") vein complex. This mineralized zone extends to over 100 meters in length, 40 meters in width and 70 meters in height. Our development plan is now incorporating the wider dimensions of this zone.

2019 Production Guidance
The Company anticipates that 2019 silver equivalent production will range between 19.5 to 21.8 million ounces, copper equivalent production will range between 107.0 to 119.9 million pounds, and zinc equivalent production will range between 261.5 to 292.9 million pounds. The increase in 2019 guidance for silver ounces and copper pounds compared to the actual 2018 production is due to the significant throughput and recovery increases planned at Bolivar and Cusi. At Yauricocha, higher copper production should be realized due to consistent copper head grades and improvement to recoveries expected from the various areas planned to be mined from the copper areas in the Esperanza Zone during 2019.
