Mt Isa Super Basin

Mt Isa Super Basin is a world class mineral province and the world’s greatest base metal region. It hosts six major zinc-lead sedimentary exhalative deposits, and several sub-economic deposits.

The Mt Isa area has been an important mineral province ever since John Campbell Miles identified deposits of copper, silver and zinc almost 100 years ago. Its long history as a mining province has delivered extensive infrastructure throughout the region, including processing plants, roads, power and waste treatment facilities. The discovery by CRA of the Century zinc mine in the early 1990s and the subsequent development of the mine, extended infrastructure into the northwest of the Mr Isa Super Basin, in close proximity to the Paperbark and Bluebush projects. The Century mine was closed in early 2017, but includes a 7Mtpa processing plant, camp and pipeline which transports mineral concentrates to the coast.

The Queensland government recently set up the North West Minerals Province Taskforce to support projects and communities, boosting minerals and infrastructure development in the northwest of the state, including in and around the Mt Isa Super Basin.

The Mt Isa Super Basin also hosts manganese, bauxite, uranium, phosphate, silver and copper deposits.
