The Onkaparinga Catchment Water Management Board (OCWMB) is responsible for an area of approx. 920 square km which includes the Onkaparinga Catchment in the Adelaide Hills and the Noarlunga and Willunga sedimentary embayments south of Adelaide, South...

To evaluate potash potential, brine samples were collected from below the dry bed of Lake Cadibarrawirracanna, and analysed for Ca, Mg, Na, K, B, HCO3, C1, total phosphate and sulphate. Potassium contents were too low to be of interest.

The exploration concept was based on searching for secondary uranium mineralisation that might be derived from the Musgrave Block basement rocks and that could have become precipitated within calcrete horizons from ponded uraniferous surface drainage...

It was proposed that the recovery of aluminium sulphate from South Australia alunite should be investigated. The only known deposit of any significance is in the Hundred of Ramsay, Yorke Peninsula, near Port Vincent. Material from this locality and...

Three samples of alunite containing various amounts of silica were subjected to heat treatment and the residues extracted with water to recover potassium sulphate. High recoveries were obtained from a sample containing only a small percentage of...

The recovery of a saleable potassium product from potassium enriched salts obtained by evaporation of salt bitterns was investigated. Four methods of treatment, namely, flotation, leaching, ion exchange and hydrolysis of the magnesium salts were...

Imported potassium salts are obtained from materials which require only simple and cheap methods of treatment. Because of the complex nature of salt bitterns, more costly methods of extraction are required. It is unlikely that any of the methods of...

The use of ion retardation as a separation procedure for the recovery of potassium from salt bitterns was investigated. The separation of potassium salts was not sufficiently great to be of practical use. It is unlikely that any variation of the...

The distribution of potassium between Dowex 50 resin and aqueous solutions containing salts of potassium and either sodium or magnesium was determined. Equilibrium curves, which were drawn from the data, showed that potassium could possibly be...

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...

Electron microprobe analysis was carried out on 3 brecciated samples to establish whether feldspar grains have identifiable overgrowths and if these are consistent with the feldspar having grown in low temperature, low pressure conditions.

Boorthanna 1 was drilled as a combined mineral/petroleum exploration hole and stratigraphic test in the southern section of the Boorthanna Trough, 29 km west of William Creek township, to: (1) penetrate the Devonian section in the search of potash...

An area centred about 30 km south-east of Burra has been explored for possible buried economic Burra style copper mineralisation and for Mongolata Goldfield type alluvial and reef gold. The host metasedimentary unit to the Monster mine, the...

An intensely faulted and folded area centred ~65 km north-east of Parachilna, where extensive hydrothermal alteration is evident in the Neoproterozoic bedrock, and where considerable past small-scale surface mining activity has occurred, but where no...

An area located ~ 70 km north-east of Ooldea Siding and 50 km east of Maralinga is being explored for the industrial mineral kaolin, and more particularly its crystallographic form halloysite, which typically occurs as microtubules or nanotubes which...

An intensely faulted and folded metasedimentary area centred ~50 km east-northeast of Blinman, where extensive hydrothermal alteration is evident in the Neoproterozoic bedrock, and where considerable past small-scale surface mining activity has...

Shallow drilling of sediments on the eastern margin of the Eucla Basin (in 25 vertical rotary mud holes with a total penetration of ~1280 m) to test for secondary uranium mineralisation, although limited by drilling difficulties, has resulted in the...

Shallow drilling of sediments on the eastern margin of the Eucla Basin (in 7 vertical rotary mud holes with a total penetration of ~110 m) to test for secondary uranium mineralisation, although limited by drilling difficulties, has resulted in the...

TARGET: Potash in Devonian evaporites within deep Palaeozoic basins. Secondary targets were coal and sulphur in the Devonian to Permian section. The area was selected because of the recent discovery of Devonian evaporites in SADM Cootanoorina 1....
