The Yauricocha Mine is located in the Alis district, Yauyos province, department of Lima approximately 12 km west of the Continental Divide and 60 km south of the Pachacayo railway station. The active mining area within the mineral concessions is located at coordinates 421,500 m east by 8,638,300 m north on UTM Zone 18L on the South American 1969 Datum, or latitude and longitude of 12.3105⁰ S and 75.7219⁰ W. It is geographically in the high zone of the eastern Andean Cordillera, and within one of the major sources of the River Cañete, which discharges into the Pacific Ocean. The mine is at an average altitude of 4,600 masl (Gustavson, 2015). The current operation is an underground polymetallic sulfide and oxide operation, providing material for the nearby Chumpe process facility. The mine has been operating continuously under Sociedad Minera Corona S.A. (SMCSA or Minera Corona) ownership since 2002, and has operated historically since 1948. Sierra Metals, Inc. purchased 82% of SMCSA in 2011. | |
