Zinkenite, a lead antimony sulfide mineral, was found on the 900 level at Sterling Hill in the early 1990’s. It is black, opaque, and occurs associated with quartz in 5-30-cm boudins within calcite (Figure 21-40), in a part of the mine which was host to seligmannite and other sulfosalts. Criddle and Stanley (1993) reported it to contain Sb 43.6, Pb, 33.2, S 21.9, Cu 0.6, total = 99.3 wt.%, and they provided reflectance data.
Part of the material referred to by Palache (1941b) as “needles of an antimony compound” was found by the writer to be zinkenite; see also berthierite.
