Xanthoconite

Xanthoconite is found as a rare mineral in several of the mines where Proustite is found. It generally forms in the same deposits as Proustite, and may even form together with it in a single matrix. In addition to their differences in crystal symmetry, Xanthoconite usually has a more orange color than Proustite.
