Bornite is an important copper ore mineral and occurs widely in porphyry copper deposits along with the more common chalcopyrite.Chalcopyrite and bornite are both typically replaced by chalcocite and covellite in the supergene enrichment zone of copper deposits.

Szenicsite is a type locality at the Jardinera No. 1 Mine, at Chile. By error, the type locality was previously given as "Tierra Amarilla". The mineral is associated with baryte, brochantite, chalcocite, chalcopyrite, chrysocolla, gold, hematite, lindgrenite, molybdenite, powellite and quartz. [3]
Chalcopyrite is an exception to most copper bearing minerals. In contrast to the majority of copper minerals which can be leached at atmospheric conditions, such as through heap leaching , chalcopyrite is a refractory mineral that requires elevated temperatures as well as oxidizing conditions to release its copper into solution.

Depending on the locality it is found accompanied by arsenic, tennantite, proustite, chalcopyrite, galenite, and baryte (in the type locality); by kutinaite and paxite (in Nieder-Beerbach); or by arsenic, bismuth, tennantite, loellingite, rammelsbergite, proustite, and quartz (in Sainte-Marie-aux-Mines).
Djurleite with quartz and pyrite from Butte, Montana (size: 9.0 x 6.2 x 4.0 cm) Djurleite is a widely distributed but little known ore mineral of copper, found in the secondary enrichment zones of copper deposits, associated with other secondary copper sulfides digenite, chalcocite, bornite, chalcopyrite and anilite with pyrite.

Alabandite forms in epithermal polymetallic sulfide veins and low-temperature manganese deposits. It occurs with acanthite, calcite, chalcopyrite, galena, pyrite, quartz, rhodochrosite, rhodonite, sphalerite and native tellurium.
