A sample of coal was substituted to determine whether any separation of bright and dull coal or coal and ash could be effected. Methods of beneficiation investigated were gravity concentration with a Humphrey Spiral, and flotation. No appreciable...

The area under review is situated in the south-eastern section of Telford Basin between co-ordinates 8,000 and 34,000, and is a southern extension of the main (Telford) coal seam proved previously on the eastern margin. Coal has been proved by close...

The Upper Goal Series have been proved over a length of 19,000 feet round the north eastern half of the periphery of a closed pound structure in the Central Area of Telford Basin. A number of coal seams have been disclosed by close boring operations...

The area recently proved extends along the south eastern margin of Telford Basin between N-S lines 300 and 9200 and is a western extension of the main (Telford) seam coal proved previously in the south eastern sector of Telford Basin. Boring...

Five bores have been drilled at Malbooma, 22 and a half miles west of Tarcoola, to test the occurrence of brown coal previously reported from water bores. One bore intersected Tertiary lignite whereas the other four entered bedrock at a shallow depth.

Drilling has confirmed the presence of a substantial body of lignite in a northern extension of the Clinton coal basin at a higher level than the main seam in the main Clinton Coalfield. The lignite has many sand and clay partings. Further scout...

Three species of Triassic freshwater molluscsa of the family Unionidae occur in the Leigh Creek and Springfield Coal Basins. One species Unio cyrensis is redescribed and two, Unio springfieldensis and Protovirgus isenschi, described as new. One Lower...

A small inlier of Permian sediments has been discovered at Mount Toondina, south of Oodnadatta. These sediments are of freshwater, lacustrine origin and consist of interbedded shales, siltstones, minor sandstones and coal seams. They contain a fossil...

Since the days of early settlement in South Australia mineral production from Yorke Peninsula has made an important contribution to the wealth of the state. Firstly, with the discovery and mining of copper in the Moonta Wallaroo district early in...

The presence of lignite in the Inkerman-Balaklava area was proved in 1922 when exploratory drilling was first carried out. A total of 30 bores were drilled between 1922 and 1950. Indicated reserves calculated on the basis of this drilling were 200...

The peat deposits in the lower South East were examined for the Electricity Trust of South Australia. They were found to be unsuitable for electric power generation. Occurrences of lignitic material in some water bores are to be further reviewed.

Eocene paralic lignitic sands of a maximum known thickness of 380 feet occur in Cummins and Wanilla Basins. A thin deposit of mid-Tertiary limestone occurs at Fishery Bay. Pliocene limestones transgress on to Archaean basement at Fishery Bay and are...

The East Boolcunda Basin was examined in order to map the Triassic rocks in detail and to assess their coal-bearing potentiality. It was found that these rocks conform to a true basin structure, similar in most respects to the Leigh Creek and...

Tertiary coal is known from a number of bores on Mulgathing station, 22 ½ miles west of Tarcoola. A reconnaissance survey of the area has shown that a large area of Tertiary sediments occur at shallow depth beneath Recent sediments and drilling is...

A review of drilling in the Lincoln and Uley-Wanilla basins has shown that low grade coaly or lignitic sediments of Tertiary age exist in depressions within the late Tertiary land surface. The coaly sediments encountered are of a low grade and beneath...
