TORONTO--(BUSINESS WIRE)--Oct. 15, 2024-- Sierra Metals Inc. (TSX: SMT; OTC: SMTSF; BVL: SMT) (“Sierra Metals” or the “Company”) reports third quarter 2024 production results from its two underground mines in Latin America: the Yauricocha polymetallic mine (“Yauricocha”) in Peru and the Bolivar copper mine (“Bolivar”) in Mexico.

Ernesto Balarezo, CEO of Sierra Metals, commented, “I am pleased to see Yauricocha operating at more than 3,000 tpd during the quarter and on track to sustainably achieve 3,600 tpd this year given the successful development below level 1120. Furthermore, Bolivar continues to deliver steady numbers quarter over quarter. Given the good results of both of our mines and the successful ramp up of our operations, we expect to exceed our consolidated production guidance for 2024.”

Consolidated Production Results

Throughput increased at both operations, therefore, consolidated throughput in Q3 2024 was 7% higher than in Q2 2024 and 7% higher than in Q3 2023 driven by higher throughput from both operations. Furthermore, copper production as of September 30, 2024, was 9% higher than during the same period in 2023.

Yauricocha Mine, Peru

Processing at a rate of 3,050 tpd, throughput at the Yauricocha mine was 266,917 tonnes during Q3 2024, an increase of 5% over the previous quarter, as the mine commenced extraction activities below the 1120 level. Head grades and recoveries for copper, silver, and gold improved in comparison to Q2 2024 but dropped slightly for zinc and lead. The higher grades were due to increased contributions from the Esperanza zone and the copper-rich zone of Pamela. As a result of higher throughput, grades and recoveries, metal production of copper, silver, and gold improved 97%, 43% and 41%, respectively, as compared to Q2 2024.

When compared to Q3 2023, Copper grades were up 14% as the mining below the level 1120 continues to move forward successfully. As a result, copper production increased by 23%.

Bolivar Mine, Mexico

The Bolivar Mine processed 401,730 tonnes in Q3 2024, which was a 7% increase from Q2 2024. Copper, silver, and gold production increased by 3%, 17%, and 12% respectively, when compared to Q2 2024.

When compared to Q3 2023, production of copper, silver, and gold increased by 11%, 50%, and 13% respectively, that was driven by 11% higher throughput and improved head grades for each metal.

Higher throughput and grades for the nine-month period ended September 30, 2024, resulted in an increase in all metal production when compared to the same period in 2023.
