The Ánimas Mine is an important Bolivian polymetallic deposit located in the south of Potosí Department, especially known for its Wurtzite, Sphalerite, Galena and silver mineral specimens. The mine forms part of a group of historic workings in the Ánimas district, developed in a high-altitude Andean environment and closely linked to hydrothermal systems related to the Tertiary magmatism of the Bolivian Eastern Cordillera.

Geologically, the mineralization is associated with intermediate- to low-temperature hydrothermal veins hosted in volcanic and sedimentary rocks, with complex parageneses rich in zinc, lead and silver sulfides. Wurtzite frequently occurs forming foliated or crested aggregates, often associated with Galena and Sphalerite.
