Our North Queensland copper mining and processing operations include the Mount Isa Mines complex, Ernest Henry Mining near Cloncurry, and copper refinery in Townsville.

Operating since 1924, Mount Isa Mines remains one of Australia's largest industrial complexes, operating two separate mining and processing streams - copper and zinc-lead-silver.

Our Mount Isa copper operations host two underground mines, including Australia's deepest underground copper mine at 1,900 metres. Ore is processed and smelted on site before being transported via rail to our copper refinery and port operations in Townsville for further processing and export.

Ernest Henry Mining is a copper and gold mining and processing operation located near Cloncurry. The operation began production in 1998 as an open pit mine and in 2011 transitioned to underground mining as part of a $589 million life of mine extension project. Copper ore is processed at the on-site concentrator and trucked to Mount Isa Mines for smelting into copper anode.


With a mining history spanning over 140 years, our CSA Mine is Australia's highest grade copper mine, and at 1,600 metres deep, it is also the second deepest underground copper mine in the country.

Located in Cobar, Central Western New South Wales, CSA Mine produces copper concentrate with a silver by-product. The product is then transported via rail to Port Waratah in Newcastle, from where it is shipped to smelters around the world.
