Thick sediment cover in the Proterozoic Curnamona Province impedes effective mineral exploration in some of the most prospective areas located away from bedrock outcrop. The objectives of the CurnaMinEx project are to test the effectiveness of surface techniques to locate buried mineral deposits. An effective technique would reduce exploration costs associated with the current practice of pattern drilling stratigraphic or structural targets defined by geophysical methods. Reconnaissance soil sampling of nine mineral prospects was used to identify four prospects that appeared to be suitable for further work, namely, Kalkaroo (Cu-Au-Mo), Polygonum (Cu-Au-Pb-Zn), Goulds Dam (U) and Christmas Ball (Cu-Au). Soil samples were taken from near surface and from deeper in the soil profile at the first appearance of Ca-salt accumulation. Minus 200 micron sample fractions were split, and the subsamples leached using various partial leach solutions; MMI-M, weak cyanide, sodium hydroxide and magnesium chloride, and aqua regia. Leachate solutions were then analysed using ICP-MS and ICP-OES for a suite of elements including Cu, Au, As, Pb, Zn and U. At Kalkaroo and Goulds Dam, the electro-geochemical CHIM technique was used as an additional method for mobile ion collection. Partial leaches consistently produced clearer anomalies when compared with the results from aqua regia digest, although some anomalies were unrelated to known mineralisation. CHIM provided a surface response at Kalkaroo that best correlated with highest-grade mineralisation at depth, and produced fewer false anomalies. However, the anomalies were mostly single elevated values. Due to time and equipment constraints, CHIM survey traverses were mostly too short in duration to provide a truly objective assessment. A more consistent surface geochemical response to mineralisation at the Kalkaroo Deposit was obtained from 10-25 cm depth samples, in the form of double-peak anomalies for Mo. This result is supported by irregular higher levels recorded for U, Au, Cu and soil conductivity measurements. Soil sampling produced quite different results to those using CHIM, and this observation suggests that there is a fundamental sensing difference between the techniques. Analytical results obtained from the Polygonum Prospect support those of previous surveys by BHP and Platsearch in which surface geochemical data were interpreted as reflecting metal distribution in basement rocks buried beneath 100 m of sediment cover. Additional work is recommended to investigate metal dispersion in the area and the likely mechanism(s) for metal mobilisation in cover sediments above mineralised bedrock. Additional samples including soil for gas analysis, groundwater, and vegetation (rosewood, mulga and mistletoe leaf) were collected also and analysed by various techniques, but these data have yet to be fully assessed.
