PbCu(AsO4)(OH)
Orthorhombic
Duftite, a lead copper arsenate hydroxide mineral, was reported from Sterling Hill by Jenkins (1993b). It was found in fractured marble at two localities within the mine. One of these was in a gravity tram; the other was in the east limb, in an old open stope north of the East Shaft and north of the (old) 150-level shaft station. Duftite occurred as bright-green 0.5 mm coatings and as extremely small microcrystals. Associated minerals in the gravity tram assemblage are anglesite, azurite, brochantite, galena, goethite, greenockite, and malachite. In the east limb assemblage the associated minerals are brochantite, goethite, tennantite, and two unknown minerals. Jenkins (1993b) provided a discussion of the formation of duftite.
