Airborne and ground magnetic surveys were conducted in the Bundulla area of the Nullarbor Plain (SA), prior to drilling a prominent circular aeromagnetic feature. 2 percussion/rotary mud holes, each drilled to TD 369.5 m, penetrated crystalline...

In a search for possible concealed Olympic Dam type base metal deposits within an area located 80 km north-west of Yalata, the licensee investigated several previously identified contiguous magnetic and gravity anomalies by performing ground magnetic...

Roxby Downs - type base metal deposits, potentially associated with linear and discrete magnetic anomalies of unknown origin in the basement, were the prime targets of exploration in an area extending between Koonalda and Hughes, adjacent to the SA/WA...

In a search for possible Proterozoic - Cainozoic unconformity - related, concealed sedimentary uranium deposits in an area of the Eucla Basin located 60 km north of Fowlers Bay, 42 rotary mud drillholes totalling 1432.4 m were put down on 5 traverses...

Continuing exploration for possible buried economic Tertiary sediment-hosted uranium deposits in the vicinity of Ifould Lake consisted of ground truthing of aerial radiometric anomalies by scintillometer surveys and chemical analysis of auger...

Following an airborne magnetic/radiometric survey, two rotary percussion holes totalling 819 m were drilled on negative magnetic anomalies to reach pre-Mesozoic basement (gabbro and meta-sandstone) in the Koonalda area of the Nullarbor Plain. No...

North Ltd's Barton Project commenced in 1990 across a number of licences progressively taken out over the western Gawler Craton, which eventually came to include EL 1865. Initial exploration for heavy mineral sand in the Barton-Ooldea area, 100-200...

Seven wells were drilled in the Oak Valley area. One well drilled at the airstrip yielded 3 L/s of 74 000 mg/L water, a quality that is only suitable to use for compaction. Three wells drilled close to swamps located west of Oak Valley gave low yields...

Deeply weathered rocks are evident from Late Cretaceous to (Late) Middle Eocene, followed by two major periods of duricrust formation in Oligocene - Early Middle Miocene.

In Wilkinson 1 drillhole, 1 carbonaceous drill cuttings sample and 5 drill core samples were examined, and compared with sediments found in the Tallaringa Palaeodrainage System and Wallira West 1. Palynomorphs are present in the drill cuttings from...

Compilation is complete. Geological problems and points of interest are discussed.

Diverse palynomorph assemblages were recovered from Wilkinson 1 and are correlated with the latest Eocene Sparganiaceaepollenites barungensis Zone (Harris 1971) in South Australia and the upper Nothofagidites asperus Zone (Stover and Partridge 1973)...

Drilling for potable ground water in recharge areas favouring local freshening of the water table aquifer (3 holes totalling 148 metres) was unsuccessful.

15 rotary coreholes have been drilled within EL 281 held by the Director-General, SA Department of Mines and Energy, to assess the potential of three areas, viz. the Pidinga Lakes, Lake Tallacootra and Chundie Swamps. All lignitic core recovered from...

Brief summary progress report.

Two major palaeodrainage systems of Tertiary age, with watersheds of up to 35 000 square km and channel lengths of 200-250 km, have been recognised and delineated using LANDSAT imagery, during 1:250 000 scale geological mapping in western South...

This outline was compiled from available seismic and drilling data. Renewed exploration activity has shown the need to upgrade information relating to the Permian and the ?Cambrian sub-basins beneath. 2 seismic programmes, to clarify the structural...

Programme of fully cored shallow holes. Aim was to investigate stratigraphy of the palaeochannels, relate this to the geology and evaluate economic potential of channel confined sediments, to test for lignite, sedimentary uranium, alluvial gold, heavy...
