The Radio Hill and Mt Sholl layered intrusions have very similar mineralisation features, namely mineralised host rocks are predominantly gabbro and plagioclase-bearing pyroxenite that form a thin marginal envelope to interlayered peridotite and pyroxenite. Disseminated and subordinate massive sulphides are located near the basal contact, and massive sulphides are largely concentrated in depressions along the basal intrusive contacts beneath the thickest sequence of mafic-ultramafic cumulates.

Exploration on the Sholl type intrusions has the potential of hosting major nickel-copper-cobalt ore bodies in structural embayments in basal contacts, as at Radio Hill. Mineralisation that has already been identified has indicated the potential of the system.
