Within the surrendered sections of the subject exploration licences in the Karoonda, Marmon Jabuk, Swan Reach, Blanchetown and Cooke Plains areas, following the conduct there of a 45.4 line km gravity survey and the drilling and geophysical logging of...

The sediments are dolomitic and clay rich mudstones and siltstones with intraformational mud conglomerates and rare cherts. The effects of flood and drought are reflected in lithological changes related to fluctuations in the physical and chemical...

Major resources of magnesite are included as sedimentary interbeds within Late Proterozoic Skillogalee Dolomite which extends the length of the Geosyncline for 820 km. Magnesite interbeds are best developed from Leigh Creek to the Willouran Ranges,...

The high environmental values of the Coongie Lakes area are recognised through their inclusion in the Register of the National Estate, their inclusion as a wetland of international importance under the Ramsar Convention, and wider acknowledgement that...

Exploration for gypsum that may have formed in Holocene salt lakes of the Ashville area, 30 km south of Tailem Bend, comprised field inspections and the completion of 14 push tube coreholes up to 1.67 m deep for a total penetration of 13.02 m. High...

Interpretation of aerial photographs revealed a paralic salt lake adjacent to the Coorong National Park near Kingston (South-East), in an area of land that was about to be sterilised for allowing ongoing mineral exploration, due to the provisions of...

A licence area covering a large salt lake (Lake Gregory) of the Cenozoic Lake Eyre Basin, and the underlying Mesozoic Eromanga Basin sediments situated to the north of the uranium-rich Mount Babbage and Mount Painter inliers, ~120 km north-east of...

Continuing exploration by Delhi of the industrial salt potential of subsurface brines in the Lake Torrens basin aimed to ascertain the potential reserves of NaCl in the southern part of the lake, and to confirm the availability of suitable brine...

Exploration aimed at alluvial gold in Cainozoic sediments derived from Umberatana Group, as opposed to previous exploration for reef gold. No encouraging assay results from 154 samples or from ground inspection and quartz vein samples in Umberatana...

Negative heavy mineral sampling results and a lack of magnetic anomalies suggest that two areas located south-west of Lake Eyre South have little potential for diamonds and / or kimberlites.

129 test pits were sampled and analysed using the water of crystallization method to identify economic gypsum above the water table.

Over the report period Agip Australia completed the drilling and geophysical logging of 39 open rotary holes totalling 3845 m to investigate if economic coal seams occur within Permian sediments of the southern Arckaringa Basin. Although the Permian...

The geological settings of Birkhead Formation oil fields in the study area are characterised by access to Permian-sourced hydrocarbons. This study has shown that in over 60% of the fields the main Nappamerri Group seal is absent; for those fields...

Very limited reconnaissance sampling of Cainozoic marginal lakebed sediments in northern Lake Gairdner has suggested that little chance exists there for discovering deposits of soluble sodium carbonate minerals.

32 rock samples, of unknown age, taken from the carbonate sequence intersected above the salt diapir section in SADME Wilkinson 1 stratigraphic drillhole, were examined petrographically to determine their possible depositional environment. Another 21...

An area of the western Murray Mallee located near Blanchetown has been explored for possible economic heavy mineral sand accumulations in Pliocene raised beach strandlines. At the outset, the licensee performed a field inspection and drew up measured...

A number of shallow Neogene salt lakes, that extend in chain-like fashion along the length of the inner Coorong and its hinterland as far south as Lacepede Bay, have been investigated for possible economic evaporitic mineral deposits that may have...

This set of reports describes the resource discovery, process of appraisal, selective extraction and product sales history relating to a group of small Holocene surficial gysum deposits located in the brackish to saline swampy hinterland extending...

Three drill cutting samples of carbonaceous sands were submitted for palynological analysis. The spore-pollen assemblages of drillholes NR 3 (from the depth interval 16-18 m) and NR 4 (16-18 m) are possibly of the latest Eocene Upper Nothofagidites...

Palynological analyses of eight cuttings and three sidewall core samples from the petroleum exploration drillhole Troas 1, in the SA offshore Otway Basin, show two distinctive microfloristic assemblages. The youngest samples are dated as Late Eocene,...
