The Coober Pedy 1:250 000 sheet area (COOBER PEDY) is bounded by latitudes 29°S and 30°S and by longitudes 133°E and 135°E in the arid north of South Australia. The only town is the opal mining town of Coober Pedy on the northeastern margin of the...

A large area surrounding the southern end of Lake Eyre, which is known to be underlain by a thinning succession of Cretaceous basinal sediments, was taken up to explore for possible economic secondary sandstone-hosted uranium mineralisation. No field...

Mineral exploration conducted in an area centred approximately 125 km west of Tarcoola has addressed targets including possible Challenger type metamorphic gold mineralisation or Olympic Dam type epithermal IOCG mineralisation, and also less deeply...

Late Palaeozoic sedimentary rocks of the Arckaringa Basin in northern South Australia include diamictite and sandstone units of the Boorthanna Formation that were deposited as lodgement till under fluvioglacial conditions. The clast size and matrix...

The central Gawler Craton is blanketed by thin sedimentary cover that ranges in age from Neoproterozoic to Quaternary. Locally, though, such cover can reach a maximum of ~500 m thickness in Permian glacial valleys or rift structures. This guide...

The WINTINNA 1:250 000 mapsheet area lies between latitudes 27° to 28° South and longitudes 133°30’ to 135°00’ East. This ~16 400 square km area includes the Marla and Cadney Park settlements, and is crossed by the Stuart Highway and Adelaide to...

TARGET: Lower Permian coal of steaming or coking grade, suitable for open cut development. EXPLORATION: Rotary drilling of 42 open and partly cored holes totalling 5122 m, including 105 m of coring, with follow-up geophysical logging. RESULTS: 7...

Critical minerals are a collection of metal and non-metal commodities considered essential for economic and industrial development, and for which there are significant concerns around future supply due to resource scarcity or geopolitical factors. The...

This report presents the results of a study jointly conducted by the Geological Survey of South Australia and CSIRO Mineral Resources which aimed to enhance the expression of geological structure in geophysical images and to derive depth to magnetic...

Exploration as part of a continuing regional search for possible diamondiferous kimberlites was undertaken 70 km west-northwest of Roxby Downs. Extensive sampling of current drainage lines in interdune swales, plus loam sampling in other...

Following an evaluation of existing subsurface data, 9 vertical percussion holes totalling 670 m were drilled to test discrete gravity anomalies in the Mount Woods area, in a search for Olympic Dam type mineralisation. The holes encountered...

Possible shallowly buried, surface-mineable coal formed within the Lower Permian Mount Toondina Formation, and similar to the coal occurring in the Phillipson Trough area, was the target of exploration carried out in the poorly defined Tallaringa...

The GOMA basement drilling program was named after the Gawler-Officer-Musgrave-Amadeus deep seismic reflection survey line, that was completed in 2008 by Geoscience Australia (GA) as part of its Onshore Energy Security Program. Funding for the seismic...

Concealed basement on GILES comprises ?Archaean to Palaeoproterozoic metamorphic rocks belonging to the Nawa Subdomain of the Gawler Craton. These are intruded by Mesoproterozoic Hiltaba Suite granitic bodies and Mesoproterozoic or Neoproterozoic...

A new generation, first edition WINTINNA 1:250 000 scale geological map and explanatory notes have been published. These documents represent the conclusion of the Geological Survey of South Australia's geological mapping program undertaken in the...

The Peake and Denison Inliers (comprising the Davenport Range, Denison Range and small basement inliers to the east) form the dominant geological structure on WARRINA. The Inliers include outcrops of Palaeoproterozoic metamorphic basement which is...
