A large tin-silver mine which closed in 1992, but reopened on a small scale since 2002 principally for specimen production. There was an 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.

Notes on the mineral list:

- Franckeite from here is frequently mislabelled and sold as "teallite". Most of the alleged "teallite" photos on this page probably really represent just franckeite, not teallite nor a mixture of the two.

- Jamesonite from here is frequently mislabelled and sold as "zinkenite", although true zinkenite does occur too (especially in association with andorite).

- Most of the crystals sold as "ferrokësterite" are really stannite (although a few "stannites" were found to be actual ferrokësterites).

- Many specimens labeled "San Jose mine" are actually from the neighbouring Itos mine.

- It's important to note that nearly all the stannites mined during the 1970s-1980s have been confirmed as stannite, but the ferrokësterite specimens mined between 2002-2004 were originally labelled and sold as stannite (mostly through Brian Kosnar), until they were properly identified by Bob Downs at the University of Arizona as ferrokësterite (https://rruff.info/Ferrokesterite/R110173).
