The target within an area centred ~35 km north-west of Cleve was massive stratiform Broken Hill and Aggenys style base metals mineralisation associated with the Lower and Upper Middleback Jaspilite units of the Hutchison Group. A world class sized Pb-Zn orebody (greater than 100 Mt) was sought. Exploration centred on the Campoona Syncline, by virtue of its high background geochemistry, (Cu, Pb, Zn, Mn, Ag), banded iron formations and Sirotem anomalies. Only low level mineralisation was indicated, and many Sirotem anomalies were found to be due to graphite schist. Ground EM soundings indicated that INPUT airborne EM survey anomalies are due to shallow conductors. Most uranium anomalies seen in airborne radiometric survey data are associated with surficial sand cover. 1143 vertical RAB holes for 10,818 m, drilled during February-March 1980 to test the bedrock strata lying above the Early Proterozoic - Middle Proterozoic unconformity, recorded low U assay values, but many base metal intercepts were recorded up to maxima of 7700 ppm Zn and 5200 ppm Pb. Later on, 8 diamond (1840 m) and 57 RC percussion holes were drilled to test selected geophysical and subsurface geochemical anomalies. Detailed geological mapping done by Shell is presented at 1:25,000 and 1:10,000 scales.
