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.
Associated minerals are: pharmacosiderite, olivenite, conichalcite, jarosite, arseniosiderite, scorodite, malachite, azurite, chlorargyrite, mixite and lavendulan.
4) Secondary arsenates including adamite, erythrite, karibibite, parasymplesite, pharmacosiderite, olivenite, schneiderhohnite, and villyaellenite from the Veta Negra mine near Los Loros.
Occurrence: Associated minerals are: olivenite, conichalcite, clinotyrolite, cornubite, kolfanite, pharmacosiderite, gerhardtite, atacamite, gilmarite, wallkilldellite-(Fe), cuprite, domeykite, algodonite and native copper.
Pharmacosiderite occurs rarely as small yellow crystals at the Gambatesa mine, found in association with olivenite, and in fossil wood at the Cassagna mine, in association with copper and arsenic minerals (Palenzona, 1991).
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.
