Minerals occurring in this leached zone included goethite, hematite, jarosite, erythrite, native bismuth, bieberite, heterogenite, nontronite and pitticite. The oxidation of chalcopyrite produced considerable amounts of limonite and malachite together with cuprite, native copper and azurite near the tops of ore zones.
They often contain inclusions of arsenopyrite, pyrrhotite, or marcasite, and are sometimes covered by a scorodite or pitticite crust.
Associated minerals are: scorodite, pitticite, bukovskyite, kankite, zykaite, gypsum, jarosite and amorphous ferric hydroxides.
