Sierra Metals Announces 2025 Production and Cost Guidance

In This Article:

TORONTO, December 05, 2024--(BUSINESS WIRE)--Sierra Metals Inc. (TSX: SMT | OTCQX: SMTSF | BVL: SMT) ("Sierra Metals" or the "Company") is pleased to provide production and cost guidance for 2025 for its two underground mines in Latin America: the Yauricocha mine ("Yauricocha") in Peru and the Bolivar mine ("Bolivar") in Mexico.

Ernesto Balarezo, CEO of Sierra Metals, comments, "We are very excited to have reached full capacity levels in Yauricocha, allowing us to operate at higher throughput rates. The latter is reflected in the increased metal production and stronger cost guidance. At Bolivar, we also expect to operate at full capacity throughout the year, despite lower projected grades due to our mining sequencing plan. Overall, looking ahead to 2025, we envision a year of full throughput at both operations, while we position our mines for sustainable long term value creation."

At Yauricocha, we expect our production to come mostly from below level 1120, complemented by the recent discovery of a new high-grade zone in the upper part of the mine. A number of investments made in 2024 and planned during 2025 should increase throughput rates beyond the name plate capacity of 3,600 tonnes per day. The expected increase in production from higher head grades and higher throughput rates will allow the mine to have a stronger cost structure in 2025.

At Bolivar, we expect to successfully complete a series of initiatives to increase throughput rates, while we forecast lower grades across all metals, mainly driven by the mine sequencing schedule. In general, our expectations are for a steady copper and silver production in 2025. Given all of this, Bolivar should have a similar cost structure in 2025 as compared to 2024.
