Exploration for possible economic stratabound copper mineralisation, carried out by Shell Minerals Exploration (Australia) over part of SML 575/703 near Arkaroola in the northern Flinders Ranges under an informal joint venture agreement with the licensee North Flinders Mines, proved unsuccessful, and therefore after six months investigation Shell withdrew its proposed interest. The Blue Mine Conglomerate and associated units, of Adelaidean age, are reported to be shallow marine deposits laid down adjacent to an ancient shoreline. Historically, copper mineralisation had been recorded from many occurrences throughout the ~27 km outcrop strike length of these units. Detailed geological/stratigraphic section mapping was carried out by Shell in an attempt to find evidence of a Zambian Copperbelt - type environment for the deposition of the lower Adelaidean units. Some similarity was noted, but this could be applied to most of the Adelaide Geosyncline. Many important Copperbelt characteristics could not be found. The transition shales, which immediately overlie the Wortupa Quartzite, were examined. As the O'Donoghue Castle mine occurs in this horizon, it was considered prospective for further copper mineralisation. Only traces of shear-controlled mineralisation were found. A detailed stream sediment sampling survey of the Skillogalee Dolomite, east of the Paralana Fault, failed to outline any areas of anomalous zinc. All main copper occurrences in the Wooltana area were visited. The Coup, Claret, Wywyana and Groan anomalies were examined in detail. It was concluded that structure was the main control of the mineralisation.
