Pyrargyrite crystals to 8mm with orange crystals of Xanthoconite. Truthfully, I did not notice the orange crystals until I photographed this specimen. These crystals fit the ID of Xanthoconite well. They stuck out well and look much like Xanthoconite. So either the mineral has not been reported at Fresnillo or the specimen is from San Martin or Bote.

Highly modified cubic crystal. It's a pretty good example from this locality as far as I can tell.
