Investigations have disclosed lead zinc mineralization as open - space filling, in the upper part of the Cambrian, Wilkawillina Limestone. Lead, zinc and copper mineralization is associated with dolomitization, facies changes, and karstic features developed at palaeosurfaces at the top of the Wilkawillina Limestone and a possible unconformity lower in the sequence. Detailed rock chip (2550 samples), soil sampling (108 samples), geological mapping, IP and Sirotem surveys have outlined 4 prospective areas (Southern, Manga, Willa and Concert prospects), showing features characteristic of Mississippi Valley type lead zinc deposits. Further work would be dependent on company exploration in the same geological environment elsewhere in the Flinders Ranges and would involve diamond drilling.
