Cambrian rocks lying beneath relatively thin Phanerozoic cover on the western edge of the Murray Basin were targeted by CSR principally for stratiform volcanogenic massive copper sulphide deposits, and for epigenetic Palaeozoic gold occurrences derived from Lower Cambrian basic and intermediate volcanics. Potential for possible granite porphyry - hosted molybdenum ore of Climax, Colorado type, and for Mount Read Volcanic Belt - analogous replacement/skarn type base metal mineralisation occurrences, were also investigated. Exploration activities included lithogeochemical analyses of granites, a photogeology study, the reprocessing of earlier BMR regional aeromagnetic survey data, the acquisition and interpretation of a 2012 line km aerial magnetic and radiometric survey, the conduct of ground magnetic surveys over 4 selected magnetic features, the drilling of 4 vertical rotary percussion and diamond holes (total 468 m, including 25 m of bottomhole coring) that were completed in basement igneous rocks, and making tentative stratigraphic correlations for volcanic rocks that were encountered by some of the drillholes. It is considered that the petrological characteristics and drill core geochemistry of the volcanics, while supporting the presence of extensive propylitic chlorite - epidote alteration, are not diagnostic of typical sources for either economic volcanogenic or skarn type major base metal deposits, so accordingly a decision was made to surrender the licence.
