In the search for Mount Gunson type sedimentary copper, 4 deep exploratory diamond drillholes (out of 22 totalling over 5000 m) intersected subeconomic mineralisation at the target base of the Sturtian Tapley Hill Formation (best value 3 m @ 1.55% Cu in CU9; also 21.3 m @ 0.51% Cu in UB16). A trial Maxiprobe survey (a vertical EM electrical sounding method) was run to try to pick faults that might define the edges of Beda Volcanics lava flows, but the method used here requires further experimentation. A 5 km long Mini Sosie seismic reflection survey spread centred on hole CU9 indicated that the subsurface topography of the pre - Tapley Hill unconformity plane is not flat-lying as was assumed, but is markedly undulose and varied. Subsequent to the flying of two airborne magnetic surveys and a re-assessment of previous magnetic data, exploring for diamonds, 13 resulting aeromagnetic anomalies that were separately drilled looking for kimberlites are now thought to be caused by local surface concentrations of magnetite and ironstone, although some deeper anomalies have not yet been explained.
