Sb2S3
Orthorhombic
Stibnite, an antimony sulfide mineral, was first reported as 0.1 mm acicular crystals, radiated groups, and aggregates from Sterling Hill by Hendricks (1960). It was later found at Sterling Hill in 1990 and verified using X-ray powder methods. The new material is opaque and gray. It occurs on the 800 and 900 levels, as microscopic crystals associated with locally abundant zinkenite, and also with arsenopyrite, realgar, calcite, quartz, pyrite, and silicates. Needles of an antimony compound were reported from the 900 level by Palache (1941b), but re-examination of Palaches crystals showed them to be zinkenite and berthierite. Stibnite is not known from Franklin.
