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...

Initial bulk gravel sampling for diamond indicator minerals, and sampling of residual surface clays for base metals, returned negative results and only background values respectively. Subsequent rotary drilling of 3 holes (total 390 m), following...

The 2000 Mt Wintinna coal deposit is located approximately 700 km north-northwest of Port Augusta in South Australia. The area has opencut potential, and is proposed for development to supply a thermal power station. Meekatharra Minerals Ltd holds...

Exploration licence 5781 was taken up to evaluate the development potential of the East Wintinna Early Permian sub-bituminous coal deposit, which is the largest known coal deposit in the Arckaringa Basin and is regarded as having the best future...

An area of 185 square km was taken up by SAPEX to allow it to evaluate afresh known sub-bituminous coal measures in the Permian Mount Toondina Formation that constitute the East Wintinna coal deposit. This deposit had been discovered by Meekatharra...

Tasman Resources' ("Tasman") Central Gawler Project tenement acreage, originally comprising seven exploration licences ELs 3339 to 3345, was initially applied for on the basis of perceived prospectivity for diamonds: however, following Tasman's...

An area of 304 square km was taken up by SAPEX to allow it to evaluate afresh known sub-bituminous coal measures in the Permian Mount Toondina Formation that constitute the Weedina coal deposit. This deposit, located ~90 km north-east of Coober Pedy,...

An area located at the south-eastern end of the Lake Phillipson Trough in the Arckaringa Basin has been taken up primarily to investigate potential palaeochannels containing lignites or pyritic sands of both Permian and Mesozoic age, which it is...

The Geological Survey of South Australia’s (GSSA) Gawler Challenge Phase 2: next generation mineral systems mapping (GP2) program allowed the authors of this report to revisits some ground-breaking landscape evolution studies with new geophysical data...

An area centred over the south-central Coober Pedy Ridge tectonic feature, 55 km south-southeast of Coober Pedy township, is being explored for possible economic buried massive haematite and magnetite within either Proterozoic banded iron formation...

The Robin Rise exploration licence, centred approximately 35 km south-southwest of Coober Pedy, covers portions of the Palaeoproterozoic basement domain known as the Coober Pedy Ridge, an east-northeast trending magnetic block of variable magnetic...

During the sixth licence year, on renewed EL 2717 covering the same area as previously, the licensee, now a wholly owned subsidiary of AuIron Energy Limited (formerly Meekatharra Minerals Limited), progressed its investigations of the geology of the...

Appraisal drilling of the previously defined south-eastern portion of the Wintinna Coal Deposit was undertaken by the licensee to try to better determine in situ resources of Permian sub-bituminous coal which might potentially be useable for coal seam...

Two separate areas in the Arckaringa Basin, designated as EL 5598 Areas 'A' and 'B', have been taken up to allow for a fresh assessment of the development potential of the large East Wintinna and Weedina coal deposits, respectively. During the first...

During licence Year 16, on its renewed EL 4534 over the period October to December 2010, South Australian Coal Limited (SA Coal) undertook a drilling campaign of 15 rotary mud partly cored vertical holes for 2871 m which included 2064.7 m of coring,...

Exploration licence 5699 was taken up to evaluate the development potential of the East Wintinna Early Permian sub-bituminous coal deposit, which is the largest known coal deposit in the Arckaringa Basin and is regarded as having the best future...

An area covering probable extensions to the Permian sediments of the southern Phillipson Trough was taken up by Southern Coal Holdings (SCH), a wholly owned subsidiary of WPG Resources Ltd, to explore for possible economic sub-bituminous coal...
