Morocco, Imiter Mine, Proustite, Xanthoconite, etc.

The Imiter Mine has become a prolific source of silver minerals. I was recently able to acquire some great specimens that feature superb xanthoconite, proustite and pearcite plus sharp crystals of acanthite ps argentite. The xanthoconite and proustite crystals are of particular interest. While the individual crystals are small, 1mm or less, they make up rich botryoids of crystals up to 10mm across. The specimens are really rich and extraordinary! Some of the crystal assemblages appear to be pseudomorphs of xanthoconite/proustite after argentite. Finally, the matrix of all of these specimens is solid quartz laced through with rich native silver. Extraordinary!

  • Lots of well formed, ruby-red crystals in clusters or balls to 3m or so in a opening on the top of this quartz-silver matrix. The opening appears to be an empty cast of some previous mineral, long dissolved. There are also lots of nice clusters of thin-platy, red pearcite crystals scattered about. A little xanthoconite and acanthite, as well.
