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...

As part of a regional evaluation of the variably exposed Lower Proterozoic metasedimentary sequence on eastern Eyre Peninsula for possible economic pitchblende mineralisation, portion of a semi-detailed airborne radiometric/magnetic survey was flown...

TARGET: Possible economic heavy mineral sand accumulations in Pliocene raised beach strandlines developed along the south-western margin of the Murray Basin. EXPLORATION: Acquisition of an airborne magnetic and radiometric survey during November...

TARGET: Unconformity related, vein-like and vein-type uranium in the Cleve Metamorphics, Katunga Dolomite and Mangalo Schist; lead-zinc sulphides of Broken Hill or Balmat-Edwards type in the Hutchison Group. EXPLORATION: Uranium exploration...

TARGET: Copper and uranium in Adelaidean sediments and Mesoproterozoic igneous rocks. EXPLORATION: A trial low-level helicopter-borne radiometric survey (using a nominal 1/10th mile flight line spacing and 50 foot mean sensor elevation) with ground...

The discovery in July 1970 of a strong surface radioactive thorium anomaly emanating from outcrop near Uno Homestead, 48 km north-west of Iron Knob, which was made by a Japanese company's geophysical prospecting party, prompted the leasing of the...

When Getty Oil took over management of the Stuart Range Project licences, it reviewed all of Newmont's drillhole data and undertook reclogging of the drill cores with the aim of correlating stratigraphy across the project area. Starting in October...

Unprospective, contrasting surficial cover and granitic bedrock gamma ray sources for 6 weak radiometric anomalies were located during ground reconnaissance of an area north of Lake Everard. Lateritic ironstones, thought to be developed above granite...

To provide a basis for interpretation of the results of radiometric logging of boreholes in the Crockers Well Area, four vertical diamond drill holes have been sunk to 50 feet depth at symmetrically placed points within an area 6 x 4 feet. These have...

The following is submitted as a summary of the present knowledge of the distribution of thorium in the State of South Australia. The aim has been to assemble the information contained in the numerous departmental reports and to record the degree of...

Trialling of precipitation and leaching techniques for the recovery of Y, Sc and heavy lanthanides from process sulphate liquors gave low recoveries. A solvent extraction process using EHPA (di-ethyl hexyl phosphoric acid) was proposed for recovering...

This bulletin contains geochronological data and interpretations from the Gawler Craton of South Australia that have been completed by Mark Fanning of The Australian National University, by Geological Survey of South Australia personnel, and by...

Stream sediment and heavy mineral concentrate samples from an area of Lower Proterozoic basement rocks were investigated for indications of copper, tin, molybdenum, bismuth and tungsten mineralisation. No significant results were obtained.

This report deals with the stratigraphy and economic geology of an area on the eastern margin of the Eucla Basin and the western margin of the Gawler Block. The area is centred upon the FOWLER 1:250 000 map area. The stratigraphic section of the...

Possible Mesoproterozoic unconformity-related uranium deposits within the Cariewerloo Basin, involving an inferred structural preparation component whereby basic intrusive members of the Gairdner Dyke Swarm cut across this unconformity in a manner...

An area of the onshore Tertiary Eucla Basin located about 170 km north-west of Ceduna and 50 km north-east of Ooldea Siding on the Trans Australian Railway has been explored for possible economic heavy mineral concentrations formed within shallow...
