The Mesoproterozoic (~1590–1586 Ma) Gawler Range Volcanics (GRV) comprise a sequence of A-type dominantly felsic volcanic rocks which were extruded in the central part of the Gawler Craton as part of a volcano-plutonic Silicic Large Igneous Province...

The diamond drillhole RC 1 is located on the south-eastern margin of the Gawler Ranges, and was drilled by the South Australian Department of Mines and Energy during 1978. This vertical stratigraphic drillhole, which was terminated at a depth of 558.0...

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 exploration target for stratabound base metals in the Red Lake area, which lies just to the east of Pernatty Lagoon and abuts the Arcoona Plateau, was the top of Pandurra Formation erosional surface. Percussion (17 holes totalling 2619 m) and...

Possible economic stratiform base metal mineralisation formed within the Woocalla Dolomite Formation, which is shallowly buried over a wide area south-east of Lake Dutton, was targeted by ongoing work in an area located west and south-west of Pernatty...

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...

Consultants were engaged by the licensee to conduct an extensive geological and geochemical investigation of a 2700 square mile area surrounding the Mount Gunson copper deposit, and to perform an interpretation of available regional aeromagnetic data....

MSDP03 is one of four diamond drillholes drilled during 2015 in the Six Mile Hill area as part of the Mineral Systems Drilling Program (MSDP). The hole was drilled vertically to 262.6 m depth over the period 25/9/2015-2/10/2015, and intersected two...

MSDP01 is one of four diamond drillholes drilled during 2015 in the Six Mile Hill area as part of the Mineral Systems Drilling Program (MSDP). The hole was drilled vertically to 1116.8 m depth over the period 31/7/2015-15/9/2015, and intersected six...

Geochemical and isotopic data from mantle-derived mafic rocks provide important constraints on our understanding of the composition and evolution of the lithosphere through time. Since the lithosphere is sensitive to tectonic processes such as...
