A fault-bounded basin of Throssell Range Group sedimentary rocks prospective for Nifty-style base metal mineralisation is contained within De Grey's tenement applications south of the Rudall River national park. The prospectivity of the area is enhanced by base metal anomalism identified during limited reconnaissance sampling of ferruginous lag by CRA Exploration in 1993 that was never followed up.

The Nifty copper deposit to the north is hosted in Throssell Range Group sedimentary rocks and was discovered by WMC Resources in 1980 when a lead-copper anomaly was identified through ferruginous lag sampling.

Specific targets for evaluation are defined by the lead-copper-cobalt-barium anomalism that remains open along strike, together with two discrete conductors within the basin identified by the recent Geoscience Australia AEM survey.

The acquisition of this project gives De Grey the opportunity to complete the first systematic evaluation of this prospective sedimentary basin initially using low cost surface sampling.
