The Radio Hill Ni?Cu massive sulphide deposit: a geophysical case history

Abstract

The Radio Hill Ni?Cu deposit is situated approximately 30 km south of Karratha in Western Australia (Fig. 1). It was originally located by Westfield Minerals (WA) N.L. in 1972 as an aeromagnetic anomaly with coincident weak Ni?Cu soil geochemistry in an area of no outcrop. Between that time and 1978 various geophysical surveys and drilling failed to locate significant mineralisation. Between 1981 and 1986 geophysical surveys and drilling by Teck Explorations Limited and Samim Australia Pty Ltd located a significant Ni?Cu sulphide deposit. Table 1 summarises the geophysical surveys carried out over the area.
