Exploration for Mississippi Valley type (MVT) lead zinc along the western margin of the Park has been confined to the upper part of the Wilkawillina Limestone of the Cambrian Hawker Group, where surface lead, zinc and copper mineralization and karstic features have been recognized associated with palaeosurface at the top of Wilkawillina Limestone, and possible unconformity lower in the sequence. Stage 1 exploration, comprising regional geological mapping, stream sediment and rock chip sampling has delineated 8 prospects : Southern, Camp, Manga, Llina, Hayward, Concert, Willa and Northern. Stage 2 exploration, comprising detailed rock chip and soil sampling, geological mapping and geophysical surveys has shown that Southern, Manga, Concert and Willa prospects have the most potential for MVT mineralization. Diamond drilling would be required to determine the extent of karstic features of the upper member of the Wilkawillina Limestone and its potential to host economic lead zinc mineralization both in the Park and elsewhere in the Flinders Ranges. No further work is proposed at this stage, pending the outcome of company exploration elsewhere in similar environments.
