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 2021 Production Highlights
- Copper production of 9.5 million pounds; a 2% decrease from Q2 2020
- Silver production of 1.0 million ounces; a 67% increase from Q2 2020
- Gold production of 2,812 ounces; a 2% increase from Q2 2020
- Zinc production of 21.1 million pounds; a 54% increase from Q2 2020
- Lead production of 8.0 million pounds; a 24% increase from Q2 2020
- Copper equivalent production of 24.8 million pounds; a 9% increase from Q2 2020
The Company achieved 62% and 25% increase in throughput as compared to Q2 2020, at its Yauricocha and Bolivar mines respectively. The Yauricocha mine achieved 328,909 tonnes during the quarter at an average rate of 3,759 tpd. Earlier during the quarter, the Company announced receipt of permit to build and operate an expansion of its capacity to 3,600 tpd plus an allowance for up to an additional 5%.
Consolidated copper production decreased 2% to 9.5 million pounds, silver increased 67% to 1.0 million ounces, zinc increased 54% to 21.1 million pounds, lead increased 24% to 8.0 million pounds, and gold increased 2% to 2,812 ounces compared to Q2 2020.
Luis Marchese, President, and CEO of Sierra Metals commented: "Despite the challenges we have faced due to the Covid-19 Pandemic, I am pleased with the relatively solid production performance in Q2 2021. The Company continues to face operational difficulties related to COVID-19 at all mines but particularly in Peru. We expect that we will continue to be impacted for the remainder of the year and as such we are reviewing our production guidance and may revise it as part of our Q2-2021 consolidated financial results."
He continued, “Looking ahead to the second half of 2021, we anticipate seeing an improvement in production results over the first half of the year as we continue to manage the implications of COVID-19 using best practices. Our goal continues to be avoiding any mine closures while ensuring that strict protocols remain in place to protect the wellbeing of our employees as well as the local communities. Additionally, we have commenced implementation on a 500,000 tonne per year magnetite concentrate plant at Bolivar which is expected to be operational early next year. We also received the final permit required for the construction and operation of the expansion of throughput at Yauricocha to 3,600 tonnes per day. We continue to work on the completion of Preliminary Feasibility Studies for all three mines to support planned expansions at all mines starting in 2024. Brownfield and greenfield exploration programs continue, and we continue to strive to optimize and improve operations with an aim of reducing costs where possible in this challenging environment.”

Yauricocha Mine, Peru
The Yauricocha Mine demonstrated its operational flexibility by processing a record 328,909 tonnes during Q2 2021, which is a 62% increase from Q2 2020. On June 16, 2021, the Company announced receipt of a permit from the Peruvian Ministry of Energy and Mines, which allows for the construction and operation at a capacity of 3,600 tpd.
The higher throughput was partially offset by lower head grades for all metals, resulting in a 7% higher copper equivalent production as compared to Q2 2020. In terms of zinc equivalents, this was a 29% increase over the same quarter of 2020. Copper production for the quarter was 11% lower, while silver, lead, zinc and gold production increased by 35%, 22%, 54% and 23% respectively as compared to Q2 2020. Due to COVID-19 operating restrictions the focus has been on larger but lowered grade ore bodies to meet tonnages with a reduced work force.

Bolivar Mine, Mexico
The Bolivar Mine processed 385,331 tonnes in Q2 2021, which is a 25% increase from the Q2 2020 throughput. The average daily throughput realized during the quarter was 4,404 tpd. Head grades for copper, silver, and gold were 8%, 27%, and 30% lower, respectively, as compared to Q2 2020. Copper equivalent production for Q2 2021 decreased 8% as compared to Q2 2020, because of lower silver (6%) and gold (15%) production offset by 5% higher copper production. Production continues to be focused more on the Mina de Fierro zone in Q2 2021 as part of our COVID-19 management plan. Mina de Fierro is a larger ore body with greater tonnages; however, the head grades and recoveries are lower than the Bolivar West zone. It is expected that as the Bolivar Mine returns to more normal operations and more ore is taken from the Bolivar West zone that we will see and improvement in head grades and recoveries in the future.

Cusi Mine, Mexico
The Cusi Mine throughput for Q2 2021 was 73,294 tonnes or 838 tpd. There was no production during the same quarter of 2020, as Cusi remained in care and maintenance throughout that quarter, due to the government-mandated shutdown to contain the advancement of COVID-19. Silver head grade for Q2 2021 was 138.94 g/t resulting in silver production of 269,000 ounces. Additionally, gold production was 142 ounces and lead production was 129,000 pounds respectively during the quarter.
