The Macquarie Arc is a newly recognised copper- gold opportunity extending south from New South Wales into the Deddick Zone (Ordovician age mineralisation) There is potential for porphyry and VMS plays, and (beneath younger cover) for equivalents to NSW Ordovician Cu-Au porphyry mineralisation (eg Cadia, Parkes) and Ordovician VMS...
correlated each of these stages recognised in active magmatic arc geothermal systems with over events of alteration and mineralisation within porphyry Cu-Au and associated high and low sulphidation Cu-Au-Ag epithermal deposits (Corbett and Leach, 1998) This work therefore complemented the earlier studies (Henley and...
