A process of rationalisation of several prior-held CRAE tenements covering Cambrian trough sediments which partly outcrop in the south-eastern Mount Lofty Ranges has led to limited ongoing exploration by that company. Ground-based follow-up of all accessible INPUT anomalies from the 1983 Murray Bridge Aerial EM Survey was completed, principally by soil and rock chip geochemical sampling and by 1:5000 scale surface geological mapping of eleven anomalies, but it also including the acquisition of ground EM, CSAMT and Sirotem survey data along traverses at certain geochemically anomalous sites. The performance of an EM34-type ground EM survey, run over four INPUT anomalies to detect any buried sulphidic conductors, was ineffective in resolving drill targets. Inclined RAB percussion open drillhole PD85HA1, sited to test the weak Sirotem anomaly found at InMB23, was terminated at 94 m after penetrating a barren sequence of interbedded micaceous phyllites and quartz-biotite schists. No significant drill chip assays were returned. Surface Cu-Au-Bi soil and rock chip anomalies associated with brecciated quartzitic schists found outcropping at several other INPUT anomalies remain untested at depth, owing to the probable lack of continuity/width of the outcropping bedrock host horizon as now perceived by CRAE.
