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.

The Chivor mining district corresponds to the historical group of emerald workings located in Chivor Municipality. It was already known and exploited in pre-Columbian times by the indigenous Muisca peoples.

Geologically, the Chivor mining district forms part of the Eastern emerald belt of Boyacá. Emerald mineralization is hosted in Cretaceous sedimentary sequences, mainly black shales and bituminous limestones of the Guavio and Macanal formations. The emeralds occur in hydrothermal veins related to Andean tectonic fracturing, resulting from the interaction between beryllium-rich fluids and chromium- and vanadium-bearing host rocks. Typical mineral associations include Calcite, Dolomite, Pyrite, and occasionally Parisite and Fluorite.
