An area of 117 square miles surrounding Carrieton Railway Siding was prospected for possible economic diapir-related base and precious metals hosted within bounding Adelaidean strata. A comprehensive regional stream sediment survey was conducted (2928 samples), plus a detailed geological and aerial photographic interpretation, and field inspection of all known mineral occurrences. Numerous low-order copper anomalies were detected in a variety of lithologies, including a maximum value of 910 ppm from Tapley Hill Formation located marginal to the northern zone of the Carrieton Diapir. No significant lead, zinc or silver anomalies were seen. Elevated barium values are present throughout most units of the local stratigraphic succession, and an inferred large deposit of vein type barite averaging 70% BaSO4 was discovered, associated with a major subvertical shear fault that transects the northern diapiric mass.
