Minera Zalamera S.A. de C.V (2009-2010)
In 2011, Hochschild Mining obtained two contiguous mining concessions, Reducción Norte Corazón de Tinieblas and Corazón de Tinieblas, in the municipalities of Malinaltepec, Zapotitlán de las Tablas, Tlacoapa and San Luis Acatlán in Guerrero state, Mexico. Exploration and exploitation of the mine was prevented by community legal challenges. These led Hochschild Mining to renounce the concessions in 2015 and in 2019 the federal mining authorities cancelled the two mine concessions completely.
