Copper

The Northern Territory is highly prospective for copper, with a large range of deposits and deposit styles, and nearly two million tonnes of historical production.

There are no currently operating copper mines in the Northern Territory (NT). Past production and projects with copper resources in the NT are located within four main geological provinces.

Projects

The Aileron Province is a significant emerging greenfields copper province. The most significant known deposit and most advanced copper project is at Jervois, 300km northeast of Alice Springs. Mineralisation at Jervois occurs in a series of strata-bound, subvertical sulfide-rich deposits. There are numerous other copper deposits in the Aileron Province, with a variety of mineralisation styles.

The Warramunga Province hosts the Tennant Creek mineral field, where the majority of the Territory’s copper production has been sourced from ironstone-hosted gold-copper-bismuth deposits. Significant copper-gold resources remain in the Tennant Creek field, and the associated Rover field, 70km to the southwest.
