Possibly some tiny pyrargyrite and pyrostilpnite
crystals are in there too: Terry Wallace at the University of Arizona is working on it.
Diaphorite and fizelyite were first observed in Canada at the Van Silver mine, and it is the second reported occurrence in Canada for semseyite, miargyrite and pyrostilpnite.
In 1978, Ty Balacko first collected samples from the ore stockpile and, with thorough microscopic examination, observed diaphorite and pyrostilpnite. Ty Balacko has provided almost all of the "unknowns" for this study.
The only common evidence of two simultaneously deposited antimony-bearing sulfides occurs at the end of the sequence where pyrargyrite and pyrostilpnite are found growing on each other.
The recently discovered Potosi vein is producing complex, lustrous, 4-mm to 5-mm crystals associated with crystals of diaphorite, pyrostilpnite and pyrargyrite, in vugs in massive pyrargyrite and miargyrite.
Small vugs in this vein contain short, prismatic pyrargyrite crystals to 2 mm, associated with crystals of miargyrite, pyrostilpnite, valentinite, pyrite and quartz.
Small (1-2 mm), well-formed orange-red crystals of pyrostilpnite having typical gypsum-like habit and flexibility have been found since 1995 in the newly opened Potosi vein.
The Silvana mine has produced an array of very fine to spectacular micromineral and thumbnail specimens including rare, fiery-orange pyrostilpnite, lustrous cubanite, pyrargyrite and stephanite as well as showy, irridescent pyrrhotite.
Clusters of lustrous disphenoids occur with pyrostilpnite, pyrargyrite, cubanite and quartz on specimens from the 42-12-1 stope.
Specially notable are microcrystals of samsonite, pyrostilpnite
and pyrargyrite, large masses of alabandite, crude pinkish gray crystals of wenkite up to 1 cm and apophyllite in colorless to white crystals up to 2 cm, rarely associated with white harmotome crystals of the same size.
Steve Pullman has obtained pyrostilpnite as scales and microcrystals from the 6700 level of the Dean mine, as well as scorodite microcrystals from the Wilson-Independence mine, both in Lander County.
Pyrostilpnite as submetallic red scales and crystals (to I mm) has been found at the Van Silver claim near Whistler, and rucklidgeite has been found with quartz from Bear Mountain, near Harrison Lake, Hotsprings (both available from Steve Pullman).
