TORONTO--(BUSINESS WIRE)-- Sierra Metals Inc. (TSX: SMT) (OTC: SMTSF) (“Sierra Metals” or “the
Company”) announces second quarter 2023 production results from its three underground mines in Latin
America: Yauricocha, a polymetallic mine in Peru and Bolivar a copper mine and Cusi a silver mine each in Mexico.
Consolidated Q2 2023 results will be released before market-open on Monday, August 14th followed with management hosting a conference call and webcast the same day at 11:00 AM EDT.
Ernesto Balarezo, CEO of Sierra Metals, commented, “As we complete our rst half of 2023, we are pleased with the continued operational recovery at Bolivar. Q2 2023 marks the fourth sequential strong quarter for the mine, achieving production of more than 400,000 tonnes, a landmark amount not achieved by this mine since Q3 2020.
These production numbers reinforce our condence in Bolivar's potential to grow further.
The Yauricocha mine operated below its full capacity of 3,600 tonnes per day ("tpd"), which was in line with our
expectations. We continue to believe that the Yauricocha mine can get back to its full production capacity of 3,600 tonnes on receipt of the permits to operate below the 1120 level.”
Mr. Balarezo concluded, “With two strong quarters of production during this year, we have shown that with our focus on safe and ecient operations combined with the various organizational changes, we can achieve the
desired results and unlock the potential of our two core mines."
