Digenite



Digenite, a copper sulfide mineral, is very rare locally. It was found at Sterling Hill, occurring as blackish, thin, pseudohexagonal, distorted, dull, platy crystals, associated with sarkinite and adamite. Although tarnished, the crystals reportedly had a very bright luster when found. An occurrence in an altered sulfide zone below the 700 level at Sterling Hill was reported by Jenkins and Misiur (1994). It has not been reported from Franklin. (Dunn, 1995)
