The southern portion of the Mount Painter Inlier contains large volumes of granitic breccia of uncertain origin. 3 vertical exploratory diamond drillholes were sited near Mount Gee and Mount Painter to determine the depth of this breccia, and to...

Specimens from the Mt Grainger Goldfield include quartzites, sandstones in which kaolinite is believed to represent earlier feldspar, siltstones, shales, diamictites of probable glaciogene origin, granitoids and andesites. Low to moderate temperature...

Large ferruginous concretions in the South Maslin Sand contain attractive botryoidal masses of iron oxides. They are prized as mineral specimens. Genesis of the concretions probably resulted from dissolution and subsequent precipitation of iron...

Geological data indicates deposits have similar Cu - U mineralization. The Mount Painter deposits occur in Radium Ridge Beds of Sturtian age unconformably overlying Radium Creek Metamorphics and underlying Mount Gee Beds. Recent work suggests these...

A strikingly attractive red and black banded iron formation of Proterozoic age outcrops at Wilgena Hill, 14 km east of Tarcoola. The iron formation is fine-grained, finely laminated and polishes to a high finish. Reserves of banded iron formation...

Geological mapping has defined a northeasterly fault trend in the Radium Creek Metamorphics and Older Granite Suite basement. Pods of granitic breccia have developed along these faults, and to the east and NE of Mount Painter, they contain uraniferous...

Rare specs of gold were found at an old ochre mine next to the township of Oodla Wirra in remnant Tertiary and Recent alluvial deposits. Gold has also been recovered from a haematite vein in Adelaidean Umberatana Group rocks. Mining and sampling has...

As part of the South Australian Steel and Energy Project, MESA targeted Palaeoproterozoic banded iron formation (BIF) at Hawks Nest as a possible iron ore resource. Detailed ground magnetic, gravity and drilling programmes identified seven deposits;...

As part of the South Australian Steel and Energy Project, Mines and Energy South Australia completed an exploration programme for iron ore at the Hawks Nest prospect during 1995 and 1996. Along with detailed magnetic and gravity surveys, the work...

This report is a summary of company exploration of the Coober Pedy Ridge and Mount Woods Inlier, northern Gawler Craton, for the period until 1993, being information extracted from data on open file with the emphasis on data referring to the iron ore...

As part of the South Australian Steel and Energy Project, MESA has targeted Palaeoproterozoic banded iron formation (BIF) rocks at Giffen Well prospect as a possible iron ore resource. Ground magnetic, gravity and drilling programmes have identified...

Following the acquisition and interpretation of 435 line km of ground magnetic surveys over selected aeromagnetic anomalies within regions of high magnetic relief on the northern Gawler Craton, 121 reverse circulation holes totalling 8609.25 m were...

Mines and Energy South Australia, as part of its contribution to the South Australian Steel and Energy Project, has defined an iron ore resource in the Coober Pedy region. Extensive ground magnetic, gravity and drilling programs identified four...

As part of the South Australian Steel and Energy Project, MESA has targeted significant aeromagnetic anomalies in the search for a possible iron ore resource. At Peculiar Knob prospect, previous company exploratory drilling in 1985 of such a magnetic...

A newly-discovered, small, non-outcropping haematite orebody has been outlined at Hawks Nest on the Stuart Shelf by MESA scout drilling. As a trial procedure a Transient Electromagnetic (TEM) survey was conducted over the known subcrop limits, the...

Mines and Energy South Australia are currently investigating the geometry and ore grades of banded iron formation deposits within the Gawler Craton near Coober Pedy, for possible use in the production of pig iron. Core samples from five diamond cored...

The Mesoproterozoic Gawler Range Volcanics - Hiltaba Granite Suite - related Olympic Dam style Cu-U-Au mineralisation, and Menninnie Dam replacement style Pb-Zn-Ag mineralisation, have served to raise the prospectivity of rocks in and underlying the...

Exploration for Challenger - type primary gold deposits that may possibly have formed within buried Archaean basement rocks in the Commonwealth Hill area, which is the purpose of one of two joint venture agreements currently in force between Minotaur...
