Exploration for possible Cambrian stratabound base metal sulphide deposits over an area in the vicinity of Meningie has targeted a number of N-S strike-elongated intense aeromagnetic and gravity anomalies presumed to originate in Kanmantoo Group metasediments. Detailed ground resistivity and magnetic surveys plus 2 programmes of drilling (14 vertical rotary/percussion holes totalling 709 m, plus 2 inclined diamond holes totalling 400 m) have confirmed that the magnetic and gravity anomalies are due to magnetite - rich banded amphibolite and gneiss containing anomalous intersections of pyrite and pyrrhotite and trace chalcopyrite. The geophysical and drilling data, plus the results of petrographic and mineragraphic studies on basement samples, have been used to refine the existing (SADME) interpretation of bedrock geology in this region. Evidence gathered suggests that the mafic rocks now tested represent an intruded, retrograded and dynamically metamorphosed igneous suite which was primarily differentiated before it was intruded along a major fault developed within the Kanmantoo Group sequence.
