The IP response of Sedimentary Copper Deposits at Kapunda, South Australia

Abstract

The Adelaide Geosyncline is host to sedimentary copper deposits that led to the formation of a copper mining industry in Australia in the mid 1800?s. During the 1960?s, historic workings at Kapunda were revisited in the search for possible extensions to mineralisation. Due to poor outcrop, geophysics played a significant role in this program. In particular the induced polarization method was used to look for primary sulphide mineralization of the Kapunda ore. The interpretation of these data relied largely on the calculation of a metal factor. A re-interpretation of these data using inversion of the PFE has revealed further information regarding the structure of the mineralised zones, and led to the identification of several targets for copper mineralisation.
