Comment: Stibarsen, Arsenic,Antimony,Valentinite and other oxides and arsenides also Calcite are found at this mine. The specimen Stibarsen is one of the pre 1990 specimens that I brought back from this site. It is a rare Native Element mineral very rarely seen in the average mineral collection. It is very good value not only for the price but because of the rarity of the mineral.
