Field reconnaissance and assessment of surface mineralisation, regional geological mapping and geochemical sampling, detailed ground magnetic and radiometric surveying, and shallow vertical percussion drilling (5 holes, total 491 feet) were carried...

The primary objective of the subject successful Accelerated Discovery Initiative (ADI) project proposal has been to determine the nature, extent and economic potential of rare earth elements (REE) mineralisation in the Benagerie Ridge portion of the...

Exploration for uranium and associated copper, gold and rare earth elements undertaken in the Mount Painter area comprised the acquisition of a helicopter-borne magnetic and radiometric survey during July 1990, plus the conduct of a stream sediment...

Exploration for possible Precambrian hydrothermal vein-style or unconformity type uranium deposits, and for any other economic metalliferous minerals, was carried out over several small inliers of Palaeoproterozoic rocks that crop out poorly through...

As part of exploration for economic metallic mineral deposits within an area of partly outcropping Precambrian calcsilicate rocks present on Kalabity Station, a field reconnaissance of all known mineralised areas was carried out initially. The...

Mineral prospecting in the Olary Province began many years ago, about the time of discovery of the great Broken Hill lode of New South Wales. Although many discoveries were made, and a number of mines worked, no significant producers survived from the...

An unusually large skarn deposit some 25 miles east of Mt. Isa is characterised by an abundance of rare earth bearing minerals in association with calc-silicates, apatite and uraninite. A mineral, containing 63.7% lanthanon oxides, which appears to be...

Drill cuttings samples taken from the depth interval 102 to 173 feet KB in the SADM Tallaringa (water) bore were separated into light and heavy mineral fractions and these were examined microscopically. The sediments studied can be divided into two...

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...

Uraniferous lodes at Radium Hill occur as shear replacements and infillings along overthrust type fractures developed within a domed anticline (northeast-southwest major axis) in granitised metasediments. At least three major shear zones have...

Uranium occurrences have now been found over extensive areas of outcropping Archaean granitoid rocks and migmatites in the Crocker well area, approximately 40 miles north-west of Olary in the north-east of South Australia. The South Australian...

No sedimentary phosphorate has been found in commercial quantities in outcropping Cambrian rocks of the Flinders Ranges. Two types of minor occurrences were defined: - 1.Those in ferruginous glauconitic limestone (consisting of pelletal apatite)....

Work copper mineralisation occurs along the northern margin of a probable intrusion of Willouran diapiric material into siltstones of the Wilpena Group. The mineralisation is mainly secondary copper carbonates but quartz-carbonate veins containing...

Rare earth minerals have been found in numerous localities in South Australia, but most deposits are small or are low in grade. There has been no production on a commercial scale. The most abundant minerals are those containing variable amounts of...

26 tons of yttrium and 4 tons scandium are extractable from 2 tailings dams with high sulphate content but less than 10% extraction possible from bulk of uranium leach residues with high solid mineral content.

No satisfactory process for direct chemical treatment of the bulk Port Pirie tailings. Effectiveness of high intensity magnetic separation for concentrating monazite and xenotime from deslimed tailing should be assessed. Slimes fraction is suitable...

A search primarily directed at assessing the stratiform copper and magnesite potential of an area centred 50 km south-west of Marree has consisted mainly of office studies comprising the collection and review of open file geoscientific data. Early in...

At the commencement of the term of the subject licence, exploratory/appraisal diamond drilling using a single rig was continued on the Olympic Dam gravity anomaly by the licensee for gathering more geological information to use to try to understand...

A search primarily directed at assessing the hydrothermal stratiform copper potential of a small area centred to the east of the Chace Range, about 35 km north-east of Hawker, consisted mainly of office studies comprising a review and evaluation of...
