Investigations consisted of: 1) economic appraisal, mapping and sampling of mineralised structures within mineral leases; 2) regional investigation to east of Mount Grainger mine (report in RB 84/31) - includes details of exploration by Abignano Ltd....

The investigation has involved a survey of known wells followed by the drilling of two rotary holes into dolomites of the Tapley Hill Formation. These have been abandoned due to high salinity and low yield. It is considered that the likelihood of...

26 hour test has shown that the discharge of the existing pump is very close to the safe yield of the well. Analysis of the drawdown curve shows that a second production well sited 150 metres from the present well in the same fissure system would...

Siliceous barite infills steeply dipping fractures within Sturtian sediments, adjacent to the southern margin of the Oraparinna Diapir. The lodes were mapped, surveyed and sampled. Barite production has been small and intermittent, 1000 tonnes from...

Aim was to test the northerly drainage between the Teetulpa and Waukaringa Goldfields for fine grained gold mineralization, and over small anticline south of Ajax Mine in the Black Hill Bore area. 90 samples were collected. No anomalous gold or silver...

144 samples from 20 sq km of Umberatana Group were assayed. Anomalous Zn (max. 190 ppm) and Pb (max. 70 ppm) occur in northwest of the area in Balcanoona Formation. Anomalous values also occur at Mount Ogilvie Goldfield.

Since 1962, recorded production from Universal Milling's barite deposit, part of Linke's lode, has totalled 28,542 tonnes. The deposit is in a Class B Environmental Area within the Flinders Ranges National Park. The steep barite lode has formed in a...

Since 1962, recorded production from Steetley's barite deposit, which forms part of Linke's lode, has totalled 6,237 tonnes. The deposit is in a Class B Environmental Area within the Flinders Ranges National Park. The steep barite lode has formed in...

Geochronological analyses of samples of the Willochra Subgroup and the Tapley Hill Formation, which unconformably overlie the Beda Volcanics, give ages of 724±40 Ma and 750±53 Ma respectively, thereby indicating that the original age determination of...

Since early 1976, 315 tonnes of structural slate have been mined. The slate is flaggy laminated carbonate bearing siltstone which splits along planar bedding surfaces to produce slabs for billiard table tops and paving. It is superior in some respects...

In a sampling programme carried out over the Sturtian Merinjina Tillite and basal Tapley Hill Formation strata on parts of the COPLEY 1:250 000 mapsheet area, 684 soil samples and 71 rock samples were collected at 25 m and 12.5 m intervals along 24...

Six holes totalling 659 m were drilled at four locations on the Bookaloo - Mount Gunson section of the Stuart Highway. Supplies of construction quality groundwater were obtained at three of the locations. There is some evidence to suggest that the...

The core complex contains carbonate breccia and raft like inclusions of rocks including dolerites. These have distinct magnetic signature and associated gravity effects. Gravity surveys have revealed steep regional gradient characteristic of basement...

Investigation of the Upalinna Diapir, located 20 km east of Wilpena Pound in the Adelaide Geosyncline, has identified a number of structural and sedimentary features normally associated with evaporite diapirs. The Upalinna Diapir is a small,...

Metropolitan Adelaide is founded on a wide variety of soils that overlie sediments and rocks. Some of the soils and sediments react to seasonal and human-induced changes in water content with marked changes in volume. The black earths and...

The principal objective of the Cooperative Research Centre for Landscape Evolution and Mineral Exploration (CRC LEME) Shields Program and the Primary Industry and Resources of South Australia (PIRSA) Regolith Terranes Group in South Australia is to...

This report summarizes information on 10 South Australian mineral deposits with individual aggregate gold resources and/or historic production of 1 tonne or more. By far the largest is the Olympic Dam Cu-U-Au-Ag deposit, with a measured and indicated...

266 summary sheets on significant lead-zinc occurrences and anomalous concentrations have been prepared by the Department's Lead-Zinc Taskforce as a data package, in the form of 5 reports, to assist in the search for lead-zinc deposits to provide...

The rationale of utilising soil air carbon dioxide and oxygen measurements as a guide to oxidising sulphide is that sulphide oxidation in the presence of water and oxygen will produce sulphuric acid, which in turn will attack any carbonates present to...

The results of a data review by MESA in 1992 to assess the prospectivity of the northern Flinders Ranges for concealed Triassic coal highlighted four main areas as having the best potential for a discovery. Following exploration for coal by MESA/ETSA...
