Abstract (in part):

Yancowinnaite is a new member of the tsumcorite group of minerals from the Kintore open cut, Broken Hill, New South Wales. The new mineral occurs in seams in a goethite-garnet matrix associated with beudantite-segnitite, mimetite, agardite-Y, carminite and chlorargyrite. Yancowinnaite is triclinic. Crystals are < 10 um in maximum dimension and occur as rosette-like aggregates forming overgrowths on gartrellite. The colour is yellowish-green to green, the streak is yellow and the lustre is vitreous. The Mohs hardness is estimated to be ~ 3. The new mineral is brittle with irregular fracture and one perfect cleavage.
