Ongoing exploration for possible economic sandstone-type uranium deposits formed in Tertiary palaeochannels in the Yarramba area, 50 km north-west of Cockburn, has included further open hole rotary drilling and downhole geophysical logging (176 holes...

As part of continued exploration over a 48% reduced licence area from prior EL 1416 (see Env 8585 for relinquishment report), 36 exploratory inclined RC drillholes (total penetration 3404 m) evaluated nine high-priority aeromagnetic targets, with some...

Exploration for possible economic primary and secondary uranium deposits, within an area extending for 50 miles north-westwards from Cockburn and Mingary, has consisted of the first-time (for this locality) acquisition by the licence operator of an...

In early 1991, Blinman 2 wildcat drilled through 2031 metres of sediments of the late Adelaidean Umberatana Group on the flank of the Blinman Diapir. Three small methane shows occurred in fracture zones in the Tapley Hill Formation.Two potential...

Base metal exploration of two lead-zinc mineralized areas previously discovered by Billiton and WMC within Hutchison Group metasediments near Mt Allalone, northwest of Buckleboo on central Eyre Peninsula, comprised ground magnetic and EM surveys, RAB...

The standing of crude oil on the beaches of southern Australia was first recorded approximately 150 years ago. This material, known locally as coastal bitumen, was used by the early maritime visitors and settlers to caulk their vessels and is the...

The abandoned and flooded Spring Creek mine, located 7 miles south of Wilmington on the north-western slope of Mount Remarkable, was visited by an officer of the SA Dept of Mines in order to check whether any radioactive minerals were present in still...

Government-led prospecting for economic uranium mineralisation, conducted in the Yankalilla area during June-September 1954, has consisted of detailed Geiger counter radiometric survey traversing of the outcropping Archaean basement rocks at 1 chain...

The purpose of the work described was to compare and contrast the petrography, accessory minerals, and absolute ages of 25 granitic and allied rock samples collected from widely scattered localities in South Australia. The processes that are...

Bumbarlow 1 (TD 720.33 m) aimed to test the lithology and petroleum potential of the Cambrian section in the central part of the eastern Arrowie Basin. It continuously cored a sequence over 300 m thick of flat-lying Proterozoic sediments interbedded...

Attempts to date granites and metamorphics within the Outalpa (Willyaman) Inlier of South Australia were made in order to determine isotopic ages of events within the Proterozoic Olarian Orogeny. Two conformable adamellitic to granodioritic gneisses...

Two major Late Proterozoic glaciations, separated by a thick interglacial interval of the order of 3000 m, are recorded in the Adelaide Geosyncline of South Australia. The earlier, Sturtian, succession includes two major glacial phases according to...

Flow banded, porphyritic acid volcanics (similar in age to the Gawler Range Volcanics) occur on Hart Island. Xenolithic within the volcanics is pink leucogranite, about 1550 Ma. Synchronous with the volcanics are grey, leucocratic alkali granites....

Coonawarra is important viticultural area. Its establishment was possible because of low salinity groundwater and suitable soil. Since 1970 groundwater levels have shown no significant decline due to irrigation and no increase in salinity. A pollution...

The intrusives are dominated by granite, N - S oriented diorite dykes up to 50 metres wide, and late stage aplitic and pegmatitic veins with variable orientation. A Middle Proterozoic age is indicated for some of the granitoids, which were probably...
