Cobalt

Prospectivity

The Territory is a potential producer of cobalt associated with ironstone-hosted copper-gold mineralisation in the Tennant Creek and Rover mineral fields. In the Rover field, Castile Resources Ltd have defined a cobalt resource at the Rover 1 copper-gold deposit, and are planning future production of pure cobalt metal. High-grade copper and cobalt intersections have been reported at Emmerson Resources Ltd’s Hermitage and Jasper Hills prospects north of Tennant Creek. Opportunities also exist to extract cobalt from tailings associated with historic mines in the Tennant Creek field. Elmore Ltd’s Peko Tailings project is currently producing magnetite, with potential to extract of cobalt and copper from the tailings.

The largest known cobalt resource in the NT is at the Browns deposit near Batchelor in the Pine Creek Orogen, where cobalt occurs within a large resource that also contains copper, nickel and lead. Sediment hosted cobalt-nickel-copper mineralisation occurs in the McArthur Basin, with significant exploration underway for sediment-hosted copper-cobalt mineralisation. In Central Australia, laterite-hosted nickel-cobalt occurs in the southwestern Aileron Province and mafic-hosted copper-cobalt resources have been defined in the Irindina Province.
