Stibnite
Gray Rock Mine, Truax Creek, Bridge River area, Lillooet Mining Division, British Columbia, Canada
Coarse-grained prismatic Stibnite crystals, here as massive Stibnite with minor Quartz matrix, were the ore at the Grey Rock Mine. Small vugs in the accompanying Quartz, as on the lower left of the photo, have micro Stibnite crystals. The Stibnite crystals are sometimes bent.
