Several classic European localities have produced exceptional examples of Tetrahedrite. These include Freiberg, Saxony, Germany; Siegerland, North Rhine-Westphalia, Germany; the Ste Marie-aux-Mines, Haut-Rhin, Alsace, France; Příbram, Bohemia, Czech Republic; and Cavnic (Kapnic), Maramureș Co., Romania. A mercury-rich variety of Tetrahedrite is well-known from the Schwazz-Brixlegg area, Inn valley, North Tyrol, Austria. The famous Herodsfoot Mine of Lanreath, Liskeard District, Cornwall, England, has produced excellent crystals of this mineral, almost always associated with golden Chalcopyrite.
Peru has produced what many believe are among the finest Tetrahedrite crystals, in a wide range of different localities. These include Casapalca, Lima Department; the Mundo Nuevo Mine, Huamachuco, La Libertad Department; the Pasto Bueno and Pachapaqui Districts, Ancash Department; the Julcani Mine, Huancavelica Department; the Huallanca District, Huánuco Department; and the Alimon Mine, Huaron, Pasco department. Another important South American locality is the Machacamarca District, Potosí Department, Bolivia.
In Mexico, large Tetrahedrite crystal clusters have come from Zacatecas at Concepción del Oro and at San Martín. In the U.S., an important locality was the Bingham Canyon Mine, Salt Lake Co., Utah. Lustrous Tetrahedrite and Pyrite
associations were found in the Daly-Judge Mine, Park City District, Wasatch Mts, Summit Co., Utah; and Tetrahedrite was one of the important accessory minerals found with Rhodochrosite
at the Sweet Home Mine, Alma, Park Co., Colorado.
