Bianchite, a zinc sulfate hydrate mineral, was first reported from Sterling Hill by Hendricks (1960), and another Sterling Hill occurrence was reported by Cook (1973). Subsequent reexamination of Cook's material by [Dunn] found it to be hexahydrite. An occurrence below the 700 level at Sterling Hill was described by Jenkins and Misiur (1994) as 2 mm "jackstraw aggregates of 20-30 micron needles or thin blades," yellow-white, and occurring on secondary calcite or on sulfides; it is likely a post-mining mineral. Bianchite has not been reported from Franklin. (Dunn, 1995)
