Principal copper minerals are enargite, luzonite
, chalcopyrite and chalcocite, with zinc and lead in sphalerite and galena.
The principal copper ore minerals are enargite (copper-arsenic sulphide) and luzonite
Gebhard and Schluter (1998) determined that some unusual crystals on older specimens from Quiruvilca, previously thought to be enargite, are in fact the world's finest crystals of luzonite
Mankayan is a vein-type deposit containing enargite and luzonite
, and in 1990 produced just over 1 Mt of ore at 1.
In neither report, however, was the luzonite

, which differs in color from enargite, is found in the Cleopatra vein and in orebodies with a high gold content.

The identification of luzonite
/famatinite from Seravezza is based on Gandolfi camera powder X-ray diffraction patterns; no precise chemical data are available, so that attribution to either luzonite
or famatinite is not possible at this time.
