SML 214A was a one-year period of extended exploration tenure by licensee RMC Minerals at the Spring Creek copper mine and environs to allow a new farminee, Base Minerals Ltd, to conduct further work aimed at delineating extensions to the known secondary copper orebody. Base Minerals conducted a prospect-scale IP/resistivity survey comprising 17 E-W traverses, which defined a highly anomalous IP chargeability zone 2400 feet long and up to 200 feet wide, showing readings that were reported to be the highest conductivities ever recorded in the Flinders Ranges area. This tantalising anomaly extends to the south of the mine, at right angles to the known mineralised fault zone, and appears to correspond to strike-related basal Sturtian black siltstone beds lying near a pronounced lithostratigraphic boundary. Follow-up percussion drilling by Base Minerals (5 widely-spaced holes totalling 1175 feet) gave very disappointing results, with no significant Cu values in any drillhole. Carbon analyses on samples from all holes ranged from 2.5-4%, the higher values corresponding to the strongest IP responses, while sulphur analyses for hole SCP1 drilled over such an anomaly returned 0.7% S for the depth interval 75-110 feet and 1.3% S over the interval 105-145 feet. Accordingly it is concluded that the large measured IP effects can be readily explained by the presence of much finely disseminated graphite accompanied by coarser well-disseminated pyrite.
