At Oumlil copper occurs as small grains, in some cases with pharmacosiderite and karibibite, and in other cases with small masses of cuprite coated by conichalcite in a section containing lavendulan and cuproaustinite.
Occurrence: In quartzites associated minerals with: arsenopyrite, scorodite, mimetite, pharmacosiderite, barium-pharmacosiderite and goethite.
Epimorphs/pseudomorphs of arseniosiderite after siderite and overgrowths of arseniosiderite on the edges of pharmacosiderite crystals were also observed at the Dolores prospect.

Thin fracture coatings and vug linings of botryoidal, dark green to black dufrenite have been observed very rarely, associated with radial sprays of strengite, minute cubic crystals of pharmacosiderite, and local sprays of meurigite.
Associated species in microcrystals include pharmacosiderite. aluminotungstite, russellite, cassiterite, and two apparent unknowns.
