TORONTO–(BUSINESS WIRE)–Sierra Metals Inc. (TSX: SMT) (BVL:SMT) (NYSE AMERICAN: SMTS) (“Sierra Metals” or “the Company”) announces second quarter 2022 production results.
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 2022 Consolidated Production Highlights
- Consolidated production guidance met with ongoing operational turnaround program at Bolivar
- Consolidated copper equivalent production of 17.8 million pounds; a 12% increase from Q1 2022
- Average daily throughput at Bolivar of 2,930 tonnes per day; a 37% increase from Q1 2022
Consolidated Q2 2022 results will be released on Thursday August 11th with a Shareholder Conference Call and Webcast to be held on Friday August 12th at 11:00 AM EDT
Luis Marchese, CEO of Sierra Metals, commented, “We continue to focus on the goals set forth when we announced our operational turnaround program, maintaining our strong commitment to health, safety, environment and the well-being of our stakeholders. In the current reduced commodities price and high inflation environment, we continue to monitor operations and production to determine any necessary modifications to our plans”
“Earlier this year, we provided a timeline for delivering initial improvements at our operations, which included a plan to ramp up production starting in Q2 of this year. Our turnaround program is starting to take effect with quarter-over-quarter improvements. At Yauricocha, we report quarter-over-quarter improvements to average daily tonnage and slightly higher grades for all metals except lead, with a 12% increase in copper equivalent production over Q1 2022. At Bolivar, when compared to Q1 2022, we report a 37% quarter-over-quarter improvement in average daily throughput during this quarter, along with slight increases to grades which resulted in a 62% increase in copper equivalent production over Q1 2022. At Cusi, an unexpected underground flooding event during the quarter resulted in a 38% decrease in quarter-over-quarter silver equivalent production.”
He concluded, “We are trending in the right direction with consolidated production improvements from our mines, having achieved production within our guidance for H1. Our disciplined approach to achieve stabilized mining operations continues, with our primary goal in mind – to achieve a full recovery at Bolivar. Infill drilling and exploration programs continue, in order to better define current resources and aim for new high grade ore bodies such as the Fortuna discovery at Yauricocha.”
Consolidated Production Results
Q2 2022 throughput from the Yauricocha Mine was 317,087 tonnes which is in line with throughput during Q1 2022. Higher grades in all metals with the exception of lead, resulted in an 11% increase to copper equivalent pounds produced. When compared to Q2 2021, throughput from the Yauricocha Mine was 4% lower when combined with lower grades, except for copper and gold, which resulted in a 21% decrease in copper equivalent pounds produced.
At the Bolivar Mine, throughput was 256,372 tonnes during Q2 2022 or 37% higher as compared to Q1 2022. Higher copper, silver and gold grades resulted in a 62% increase to copper equivalent pound production when compared to the previous quarter. When compared to Q2 2021, throughput at Bolivar was 33% lower and grades were lower for all metals except for gold, resulting in a 46% decrease in copper equivalent pounds produced.
At Cusi, throughput was 66,722 tonnes during Q2 2022 or 21% lower as compared to Q1 2022. Lower throughput and lower grades resulted in a 38% decrease in silver equivalent production. When comparing Q2 2022 to Q2 2021, silver equivalent production remained flat due to higher head grades for all metals, despite a 9% decrease in throughput.
Yauricocha Mine, Peru
The Yauricocha Mine processed 317,087 tonnes during Q2 2022, which was in line with throughput in Q1 2022. However, we note an improvement when compared to Q1 2022 copper equivalent pound production, with an 11% increase to 12.1 million pounds due to improved grades in all metals with the exception of lead.
When compared to Q2 2021, there was a 4% decrease from the 328,909 tonnes processed in the same quarter of 2021. Negative variances in the lead and zinc grades and positive variance in the copper grade resulted from mining in the Esperanza ore body. Despite a 39% increase in copper production, copper equivalent production was 21% lower than the Q2 2021 production, due to lower quantities of silver, zinc and lead produced.

Bolivar Mine, Mexico
The Bolivar mine processed 256,372 tonnes in Q2 2022, compared to 187,556 tonnes in Q1 2022, which was a 37% increase. Higher production as well as higher grades in all metals resulted in a 62% increase in copper equivalent pound production.
When comparing Q2 2022 to Q2 2021, tonnes were 33% lower and grades for copper and silver were 27% and 35% lower respectively, while gold was 14% higher. The change in grade profile is due to the depletion of Bolivar West and the new contribution of the Bolivar NorthWest orebody. When compared to Q2 2021, the decrease in throughput and grades resulted in a 46% decrease in copper equivalent pounds produced during Q2 2022.
While the operational turnaround effort continues at Bolivar, we expect higher plant throughput for the balance of the year, due to improved access to mineralized areas including higher contribution from the Bolivar Northwest zone.

Cusi Mine, Mexico
Operating at an average throughput of 763 tpd, Cusi processed 21% fewer tonnes of ore in Q2 2022 as compared to Q1 2022, mainly due to the unexpected underground flooding issues in the quarter. The decrease in grades and throughput at the Cusi Mine resulted in a 38% decrease in silver equivalent ounces.
When comparing Q2 2022 to Q2 2021, the mine processed 9% fewer tonnes of ore. Silver production decreased 4% to 0.3 million ounces, gold production increased 13% to 160 ounces and lead production increased 112% to 0.3 million pounds. Silver equivalent production of 283,000 ounces for the quarter was in line with Q2 2021.
