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. Bornite is also found as disseminations in mafic igneous rocks, in contact metamorphic skarn deposits, in .

Chalcocite (copper sulphide) is an important ore mineral of copper. It has more than double the copper content by weight % of chalcopyrite (the most common ore of copper) and is therefore a much more profitable ore mineral. It was the main copper ore worked in the rich West Penwith mines of Geevor, Botallack and Levant. This specimen is from Geevor and was collected underground in 1964. It ...
