Preparation of lightweight aggregate from a sample of Tapleys Hill shale, as successfully achieved by 'bloating' (the expansion of a viscous melt of crushed rock particles by trapped gas released during fusion in a rotary kiln), is described. Six...

In an area located approximately 7 to 20 miles north of Orroroo, a number of previously worked old small barite and copper prospects were examined in detail, and recommendations were made for additional work to be done, e.g. bulldozer trenching, soil...

TARGET: Possible commercial oil shale beds in either the Cretaceous Madura Formation or the Cambrian Observatory Hill Formation; possible Mississippi Valley - type lead-zinc deposits within the Observatory Hill Formation; economic lignite seams...

An investigation of several well-defined and relatively high intensity aeromagnetic anomalies (up to 20,000 gammas), disclosed by an Aero Services Corp. 1962 regional survey conducted partly in the vicinity of Mount Woods, was undertaken in a search...

No economic or potentially economic mineralisation was noted during a geological survey of the old surface and underground gold workings on the Mount Grainger Goldfield. The Mount Grainger anticlinal structure is considered by the authors to be quite...

Appraisal of the historic Spring Creek copper mine area, located approximately 8 miles south-southeast of the township of Wilmington, commenced with an IP survey of the immediate mine site, where the lode outcrops over some 20 feet in weathered...

SML 113 covering about 1000 square km of Upper Proterozoic and Lower Cambrian sediments, and scattered masses of intrusive diapir, was taken out in the vicinity of Beltana to explore for copper deposits analogous to those found by SA Department of...

Possible stratiform / hydrothermal syngenetic base metals deposited on the flanks of the Pernatty Culmination in the vicinity of fault lineations were targeted in an ongoing regional drilling programme (in part comprising 7 vertical rotary percussion...

An area surrounding Beltana in the Flinders Ranges, which is known to contain low level base metal mineralised Adelaidean and Cambrian sedimentary rocks and diapiric intrusive structures, has been prospected by a combination of photogeological studies...

Exploration for possible economic stratabound/stratiform copper, zinc and vanadium mineralisation occurring within a large area located south-west of Marree has consisted of geological field mapping and regional stream sediment sampling (3470...

Exploration of the 'Burra Ridge' highland of Adelaidean Burra Group rocks outcropping along a direct line between the towns of Burra and Robertstown, which has a history of mineral production from nine major early copper mines and many smaller...

Exploration undertaken in the vicinity of Reaphook Hill addressed the potential of previously reported anomalous stream sediment zinc and manganese values found in the Wilkawillina Limestone at locations a few miles north of the hill, and also...

Several small areas in the vicinity of the Mount Coffin Diapir, which covers ~5 square km within the north-central Flinders Ranges immediately to the south-east of Copley, have been explored with the hope of finding additional copper resources near...

A north-south elongated, narrow licence area centred ~30 km north of Whyalla and covering ground inland adjacent to the Lincoln Highway, has been taken up to explore for possible economic buried stratiform/stratabound, Mississippi Valley type...

At the historic Bird-In-Hand mining claim, where previous mine exploration drilling beneath the old workings by current licence operator Maximus Resources had delineated an inferred remaining gold resource of 53,000 ounces over the depth extent from...

Evaporite minerals in black shale at the base of the Early Cretaceous Bulldog Shale near the western margin of the Eromanga Basin were the target about 50 km NE of Coober Pedy. Reconnaissance mapping, soil sampling, auger drilling and the backhoe...

Reconnaissance geological mapping of existing, previously quite productive opal workings in the White Hill area of the Stuart Range 'Breakaway' country, 100 km south-east of Coober Pedy, was followed by exploratory and infill narrow-hole auger deep...

An area taken up to comprise the middle member of a block of three tenements located in the Myall Creek region ~ 30 km west-southwest of Port Augusta has been explored for possible economic buried stratabound copper sulphide mineralisation as well as...

This report presents detailed industry-derived statistics on the State's output and sales values of earth resource commodities realised during the six month period ended 30 June 2008, and compares the data with that returned for the previous six...
