Sociedad Minera Corona S.A. is a Peru-based polymetallic mining company engaged in the exploration, extraction, beneficiation, and commercialization of base and precious metallic ores and mineral concentrates. The company conducts its primary mining and metallurgical operations at the Yauricocha underground mining unit located in the Yauyos Province within the Department of Lima, Peru, utilizing the Chumpe differential flotation processing plant. Its systematic product offerings include copper concentrates; zinc concentrates; lead concentrates; silver-bearing lead concentrates; and precious metal contents encompassing gold and silver recovered as commercial by-products within its base metal concentrates. Sociedad Minera Corona S.A. commercializes its mineral concentrate production primarily to domestic and international commodities traders, refining facilities, and industrial smelting companies. The company operates as an operating subsidiary of Dia Bras Peru S.A.C., which is controlled by Sierra Metals Inc. In recent operational and corporate developments, the company secured official regulatory authorizations and environmental permits to develop and exploit high-grade mineralized zones below the 1120 level at the Yauricocha mine, facilitating a substantial operational ramp-up that restored plant throughput to its full authorized capacity of 3,600 metric tonnes per day and generated record multimetal production recoveries. In addition, the company has undertaken deep-level infill and step-out diamond drilling campaigns to upgrade and expand its mineral reserve and resource inventory, while its controlling shareholder, Sierra Metals Inc., entered into a definitive business combination agreement with Peruvian mining group Alpayana S.A.C. to consolidate mining and processing assets across the central Peruvian mineral belt. Sociedad Minera Corona S.A. was incorporated in 1993, maintains its corporate headquarters in Lima, Peru, and lists its common shares on the Lima Stock Exchange under the ticker symbol MINCORC1.
