An area located 100 km south-east of Oodnadatta, encompassing Adelaidean sediments and associated intrusives of the Peake and Denison Inliers, was considered prospective for copper and gold mineralisation, while potential for diamonds was inferred from widespread distribution of indicator minerals to the west. Re-processing of available aeromagnetic data defined nine anomalies considered to have kimberlitic signatures. Lack of indicator minerals from past sampling downgraded the diamond potential, and exploration for copper-gold mineralisation was not undertaken as efforts were concentrated elsewhere.
