| Copper-glance readily alters to other minerals, such as malachite, covellite, melaconite and chalcopyrite. |
| Covellite and chalcocite have been reported from the Property, generally interpreted to be associated with the base of the oxidation zone. |
| In a similar reaction, it can also help to retrieve copper from chalcopyrite and covellite. |
| Good crystals of covellite have not been reported from the District. |
| Examination of thin sections confirms the presence of widespread pentlandite together with millerite and lesser covellite. |
| Other minerals present in the upper zone include bornite, covellite, chalcocite, prousite, hematite, kaolin, and illite-smectite. |
