An investigation of historic shallow workings on secondary copper mineralisation associated with a narrow fracture zone in the Moonabie Porphyry comprised 1:1000 scale surface mapping, geochemical sampling, petrographic studies and an IP survey. Minor...

Ground scintillometer work carried out by BHP over its SMLs in the Middleback Range area has been shown not to be an effective reconnaissance tool for finding uranium anomalies, but it does have demonstrated value for identifying sources of...

Two separate orientation geochemical sampling programmes have been undertaken during 1969 over BHP's Special Mining Lease areas near Whyalla. In the Pandurra Station area, shallow residual soils over known mineralised Carpentarian bedrock were...

During early 1970 BHP investigated an area on Roopena Station, 20 miles north-northwest of Whyalla, for possible late Meso- to early Neoproterozoic stratiform copper associated with the basal Adelaidean unconformity. Previously, interesting minor...
