Chalcostibite is rare at Rudabanya, found in small cavities in the spongy siderite ores of the Polyanka, Andrassy I and III sections.
Skinnerite is closely associated with chalcostibite and chalcocite.
Among these minerals are arsenopyrite and chalcostibite, both of which occur sparingly as isolated euhedral crystals in some of the massive native antimony; jamesonite, which was noted as an inclusion in a single grain of gudmundite; and rare, scattered grains of pyrite and chalcopyrite.
And a real killer find was the chalcostibite belonging to Frederic and fellow Frenchman Christophe Dubois.
The crystals are a dull metallic gray, and form needle-like or bladed crystals to 1 cm, occasionally associated with slightly iridescent metallic black chalcostibite crystals to 1 cm on brown siderite crystals.
