This paper provides a formal definition of the Cultana Subsuite, outlining the igneous petrology of the intrusion, its geochemical characteristics, and the nature of hydrothermal alteration and brecciation affecting the rocks. The Cultana Subsuite is...

Infill aeromagnetic and ground gravity surveys undertaken approximately 50 km west of Port Augusta were followed by an IP survey and lag sampling. Anomalous Cu and Au values were returned, but only a minimal IP response was recorded. Regolith mapping...

Exploration targeted copper porphyry style mineralisation in the Cultana Homestead area, and was concentrated at two locations where traces of copper mineralisation were found at the surface. At Old Point Lowly mine, malachite concretions were found...

Surface geological mapping and open hole rotary drilling of 21 stratigraphic holes totalling 8717 m were carried out within the relinquished ground portion, which from reviewing the results is regarded as having low potential for copper and other base...

Cultana is located on parts of the north-eastern Eyre Peninsula, northern Spencer Gulf and south-western Flinders Ranges, and is underlain by rocks of the Mesoarchaean-Mesoproterozoic Gawler Craton, the Neoproterozoic Adelaide Geosyncline, Torrens...

This report describes the results of a MESA consultant's second generation regional geological mapping and drillhole data interpretation work for the Roopena and Uno 1:100 000 sheets on PORT AUGUSTA, performed during 1993 and 1994 as part of the SAEI...

The Cultana basement 3D Geological Model covers a region which includes the Roopena, and western half of the Cultana, 1:100,000 mapsheet areas. The subsurface geology that has been modelled comprises a succession of deformed Palaeoproterozoic...

This inaugural regolith map of the southern Gawler Ranges margin provides a valuable regional overview of the main regolith types and their associated landforms, plus a general outline of the major areas of bedrock or regolith-dominated terrain, as...

This work was undertaken to try to determine the age relationships between the various formations in the Moonabie Range, namely, the Moonabie Grit, the Moonabie Porphyry and the Corunna Conglomerate. The stratigraphic relationships that were observed...

Poorly described Lower Carpentarian basement ?basic igneous rocks, occurring over an area of approximately 65 square miles situated 3 to 8 miles east and north-east of Iron Knob, were investigated by BHP to establish their exact nature and to assess...

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...

A small area located on the eastern side of the Roopena Fault Zone, proximal to the south-eastern margin of the Gawler Ranges, is being explored for possible buried epigenetic gold and silver mineralisation, or IOCG type base metal sulphide...
