Sierra Metals Reports Q1 2024 Production Results, Including Record Quarterly Copper Equivalent Production at Bolivar

19 April 2024

Sierra Metals Inc. is pleased to announce first quarter 2024 production results from its two underground mines in Latin America: the Yauricocha polymetallic mine in Peru and the copper-producing Bolivar mine in Mexico.

Ernesto Balarezo, CEO of Sierra Metals, commented, “During the first quarter of 2024, the Bolivar mine achieved another record quarter, continuing its upward trend of quarterly increases in metal production. Meanwhile, we are very pleased to announce that after receipt of the permit to mine below the 1120 level on February 21, 2024, we have already initiated the development activities. We expect to reach full capacity at Yauricocha by Q4 2024, while continuing to manage every aspect of the mine to maximize production levels above the 1120 level. Additionally, I am happy to announce that we are on track to meet our annual guidance. Overall, for both operations, 2024 has gotten off to a good start with expectations of further operational improvements as the year progresses.”

Consolidated quarterly throughput during Q1 2024 was 638,916 tonnes, which is a 23% increase from the same quarter of 2023, as both mines registered increases in throughput during Q1 2024 compared to Q1 2023. When compared to Q4 2023, consolidated throughput was 5% lower.

Grades from the Bolivar Mine during Q1 2024 were higher than Q1 2023 and Q4 2023, while Yauricocha experienced declines in copper grades during Q1 2024 compared to Q4 2023, as well as decreases in grades for precious metals compared to both Q1 2023 and Q4 2023. These lower grades from the Yauricocha Mine were primarily due to the limited available ore above the 1120 level. However, the Company expects that grades will improve as the development below 1120 level progresses.

Consolidated production for all metals except zinc increased in Q1 2024 compared to Q1 2023. When compared to Q4 2023, consolidated production for copper, silver, and gold were lower by 7%, 9% and 4%, respectively.

Yauricocha Mine, Peru

Throughput from the Yauricocha Mine during Q1 2024 was 240,686 tonnes, a 10% increase over Q1 2023 due to increased access to mining areas. As compared to Q4 2023, mine throughput was lower given the natural depletion of ore zones in the upper part of the Yauricocha Mine. These volumes are expected to improve as the development below 1120 level progresses.

For Q1 2024, copper and lead grades remained aligned with Q1 2023, but gold, silver, and zinc grades were lower. Compared to Q4 2023, zinc grades were higher but copper grades decreased, attributable to the reduced output from the high-grade copper ore bodies (Pamela and Kimberly). Mining activities primarily focused on the lower-grade orebodies, such as Fortuna and Esperanza Distal, which were originally contemplated in the mine plan for the quarter.

Copper equivalent production of 8.6 million pounds for Q1 2024 was a 20% decrease from Q4 2023 as the drop in the throughput rates and lower copper, silver and gold grades impacted metal production. When compared to the same quarter of Q1 2023, copper equivalent production remained in line as increased copper and lead production were offset by the decline in zinc, gold, and silver production during Q1 2024.

Bolivar Mine, Mexico

Throughput from the Bolivar Mine during Q1 2024 was 398,230 tonnes, a 33% increase over Q1 2023 and a slight 3% decrease compared to Q4 2023. The increase over the same quarter of the prior year was driven by advancement in the mine’s development, which allowed for improved access to mineralized zones.

The improved access and mining activities in the high-grade Dulce zone drove grades higher for all metals when compared to Q1 2023 and Q4 2023. Production for copper, silver, and gold was 48%, 46% and 32% higher, respectively, when compared to Q1 2023. In comparison to Q4 2023, these increases were 13%, 14%, and 7%, respectively. The Company is dedicated to continued exploration efforts aimed at further understanding the continuation of Dulce, yielding promising results so far.

Copper equivalent production of 11.4 million pounds from the Bolivar Mine during Q1 2024 was a 44% increase over Q1 2023 and 12% increase over Q4 2023.
