Latest Carboniferous and earliest Permian ages are determined for 3 drill core samples.

Brief summary progress report.

There are no known major water resources in the northwest Gawler Craton area. The groundwater that is used for stock occurs in Tertiary sediments and weathered basement overlying the Gawler Craton. A Transient Electromagnetic (TEM) survey which was...

There are no known major groundwater resources in the Garford area, which borders the Barton and Ooldea Ranges dunefield and Great Victoria Desert southwest of Coober Pedy. The groundwater that is used by graziers for stock watering occurs in...

An area centred ~90 km west-northwest of Tarcoola and ~15 km south of the Challenger gold mine is being explored for possible economic metallic mineralisation that may have formed in igneous and metamorphic basement rocks, ideally in places where the...

Stockdale's exploration for diamonds in the Barton region, at the start of the licence period, commenced with the evaluation of 136 potential kimberlite targets generated by the detailed in-house interpretation of data acquired from an extensive new...

The existence of a Permian trough incised in crystalline basement of the Gawler Craton near Mulgathing has been verified by seismic and gravity measurements, followed by drilling. The trough is about 4 km wide and may reach depths of 800 m or more. In...

Three separate small sub-blocks forming a licence in the Tarcoola district have been explored for possible economic buried Tertiary sandstone-hosted uranium mineralisation and for any other metallic mineralisation that may have formed in underlying...

Coal exploration performed by CRA in the eastern part of the Mulgathing Trough comprised a literature review, stratigraphic interpretation of previous drillhole and geophysical data, and the planning of a 6-hole rotary exploratory drilling programme...

Following reappraisal, the relinquished sector is considered to hold little potential for occurrence of Tertiary brown coal in the Gibraltar Rocks area. Sampling gave no encouragement to search for base metals or kimberlites.

Following the conduct of a geological review of known gold and iron occurrences in an area lying to the north of the Tarcoola Goldfield, it was decided that exploration licence tenure over this ground would not be retained.

Following initial assessment of available data, exploration for copper, gold and base metals in an area 60 km west of Tarcoola concentrated on regional calcrete sampling. Analysis for gold and a suite of base metals indicated several areas of...

After two intensive regional reconnaisance programmes of heavy mineral sampling, backed up by air photointerpretation and drill hole record checks, the licensee has concluded that the tenement areas relinquished have a low prospectivity for diamonds....

Interpretation of aeromagnetic data, plus regional geochemical calcrete sampling, 100 km north-west of Tarcoola, identified four prospects with low-order (5-6 ppb Au) anomalies. Infill calcrete sampling of these sites led to the conclusion that...

Shallow Precambrian crystalline basement underlies the greater part of the BARTON 1:250 000 map area. Thicker Neoproterozoic, Cambrian and Carboniferous Permian sediments occur in the northwest, with the southern margin bounded by the Karari Fault...
