Survey was located on 7 seismic lines. Gravity interpretation indicates deep basement structure associated with Precambrian sediments. Features within the Tertiary - Cainozoic units are delineated. Further work is recommended to investigate possible Tertiary palaeochannels and faults to upgrade sedimentary uranium exploration within the Wertaloona area. Relatively shallow basement exists west of the Wertaloona Fault and base metal exploration may be warranted. Small number of structures can be correlated with faults within the Middle and Early Cambrian units, but more data is necessary, especially SE of Arrowie Outstation, where basement high is suspected.
