Bauxite

The Northern Territory is a major producer of bauxite from the Gove mining operation in northeastern Arnhem Land. 

Production

Since mining at Gove began in 1971, more than 236 million tonnes of bauxite has been mined. Total remaining reserves and resources at Gove total 201 million tonnes at an average grade of 49.5% aluminium oxide. 

An alumina refinery operated in Gove from 1972 to 2014 but is now in care and maintenance, with all bauxite now exported. Production at Gove in 2014/15 was 7 million tonnes of bauxite.

Geology

A number of other lateritic bauxite deposits are known along the northern coastline of the NT. These deposits - like Gove - have developed over Cretaceous rocks during the Cenozoic, including on Marchinbar Island, Elcho Island, Croker Island and the Coburg Peninsula. 

Further potential exists in Arnhem Land across untested lateritic areas west of Woolen River, north of the Peter John River and in the King River area.
