San José Mine, Oruro City, Cercado Province, Oruro Department, Bolivia

StandardDetailedBy ChemistryMineral Photos (170)Site Photos (5)MapsSearch Google

A large tin-silver mine which closed in 1992, but reopened on a small scale since 2002 principally for specimen production. There was abundant production of specimen-grade sulfosalts, especially during the 1970s, including by far the world's best andorites and plagionites, and good specimens of zinkenite, franckeite, stannite and others. Franckeite from here frequently sold mislabelled "teallite". Jamesonite from here frequently sold mislabelled "zinkenite", although zinkenite does occur. Many specimens labelled "San Jose mine" are actually from the neighboring Itos mine (qv).
