RB 59/00139 Geological report no. 2 on the Koppio, jaspilite complex, Hundred Koppio, southern Eyre Peninsula, Cummins 1-mile map.
Drilling results confirm the general synclinal structure. The jaspilite complex appears to be too low grade, too deeply weathered and too narrow to be of immediate economic interest. The western flank and main synclinal axis need more exploration for...-
