Economy The Greenvale mining lease has undergone extensive exploration work by Straits Resources and Metallica Minerals for the purpose of reopening the nickel and cobalt operations. The surrounding areas have extensive nickel and cobalt mineralisation.

According to the managing director of Metallica Minerals, Andrew Gillies, the deposit's quality and purity are remarkably high. Scandium oxide is a critical component of solid oxide fuel cells which have promise for the efficient direct production of electricity from low carbon gas fuels.
