An operating copper-gold mine located 2 kms south of Cloncurry.
The Great Australian Mine was discovered by the explorer Ernest Henry in the 1867, and Cloncurry was settled to service this mine and others nearby which were developed subsequently. The mine was operated spasmodically till 1919, due to its isolation, but reopened in about 1995. It now operated by CopperChem and is still being open cut mined today. Ore is currently mined in three open pits at a rate of approximately 700,000 tonnes per year. In 2009 indicated and inferred reserves were shown as 2.2Mt @0.14g/t Au and 1.55%Cu.
The ores were fault-related veins in early Proterozoic dolostone, metadolerite and metatuff. There was an extensive supergene zone rich in native coper, cuprite and chalcocite; the primary ore was chalcopyrite rich.
