Stratiform base metal sulphide deposits and sedimentary uranium accumulations were targeted in the Stuart Creek area, which straddles the Torrens Fault on the eastern margin of the Stuart Shelf. Two airborne magnetic and radiometric surveys totalling...

During June-July 1972, 35 shallow vertical rotary percussion drillholes for a total penetration of 877 m were completed within the Ediacara Fault Zone to test for economic base metal mineralisation, the majority of the holes being sited at locations...

WMC's Stuart Shelf exploration activities from 1975 to 1985 have sought mainly Olympic Dam style mineralisation (copper - uranium - precious metals in haematitic breccia host rocks), with lesser emphasis directed at: possible distal analogues of the...

Survey between Nectar Brook reservoir and Redcliff Point over the proposed Redcliff petrochemical plant indicates that a narrow valley, filled with up to 200 metres of low density sediments, occurs beneath the western portion of the site. Subsidence...

Depot Creek is one of few localities with sedimentary contact between the Burra and Callanna Groups. The Depot Creek 1 drillhole [TD 874.35 m] provided subsurface control for making an interpretation of the structure of the eastern margin of the...

Geology is summarised based on literature and recent geological mapping. The Adelaidean outcrops in the Willouran Ranges where it is folded, fractured and cut by partly diapiric crush zones. The oldest Adelaidean, Callanna Beds, occurs as blocks in...

The Northern Power Station, presently under construction, is the third power station to be built at Port Augusta. Two previous stations (Playford A and B) were constructed during the 1950s, although investigations into the feasibility of using the...

Contains summarised geological logs of 93 diamond drillholes and 4 percussion drillholes that were drilled by SADM/SADME and by exploration companies, including the logs of 2 early water bores drilled near Port Pirie. The holes penetrated Cambrian,...

Pre-Mesozoic rocks are best exposed in the Willouran Ranges SW of Marree, but inliers occur as far west as Stuart Creek. These approximate the junction of the Stuart Shelf (to the west) with the Torrens Hinge Zone, which extends east to the Norwest...

The Torrens Hinge Zone Project aimed to demonstrate the existence of prospective metalliferous rocks beneath the Cainozoic cover, to stimulate exploration and to investigate the transition between the Adelaidean sequences of the well-exposed Adelaide...

Beda Volcanics and Backy Point Formation crop out in only a few localities on northeastern Eyre Peninsula, north of Whyalla, but drilling has shown them to extend for approximately 170 km to the north below younger cover. The Beda Volcanics comprise...

As part of Torrens Energy' pioneering hot rock geothermal resource exploration in the central part of the Torrens Hinge Zone, a two-dimensional reflection seismic survey traverse was acquired using low-impact Vibroseis signal source equipment in the...

Economic deposits of iron-oxide associated copper-gold mineralisation of the Moonta-Wallaroo or Olympic Dam style, hosted in Palaeoproterozoic basement rocks of the Moonta Sub-domain, were targeted by exploration in three now surrendered licences,...

The recent Geoscience Australia - run regional seismic traverse across the Stuart Shelf has revealed the architecture of the buried Neoproterozoic sediments there, and also that of the structures created during the Delamerian inversion. Dewatering of...

Investigation of an anecdotal historic ?alluvial gold occurrence located adjacent to the Lochiel - Ninnes Road has consisted of a field reconnaissance and some surface geochemical sampling (31 soil, 2 weathered metasedimentary bedrock) along a 20 m...

An area located immediately north of Port Augusta was taken up to explore for possible economic gold, base metals and diamonds. However, continuing uncertainties concerning who were the correct holders of Native Title rights and a consequent lack of...

Exploration for possible sediment-hosted base metals and for Olympic Dam style deposits, in an area bordering the eastern side of Lake Torrens and located approximately 48 km west of Leigh Creek, has consisted only of geophysical data reprocessing and...
