An area located approximately 40 km north-west of Hawker in the southern Flinders Ranges has been explored by Copper Range as part of a regional programme being conducted in the central Adelaide Geosyncline, which is targeting large alteration zones...

The PORT AUGUSTA 1:250,000 mapsheet area covers the north-eastern part of the Eyre Peninsula, the northern Spencer Gulf and the south-western Flinders Ranges, and extends from latitude 32°00'S to 33°00'S and longitude 136°30'S to 138°00'S. The main...

In May 1980 Amdel was asked to carry out preliminary investigations to determine the beneficiation potential of the various minerals present in a sample of Warrakimbo micaceous iron oxide. In the first stage of the work a mineralogical examination and...

Exploration within an area of outcropping Adelaidean sediments located 80 km north-east of Hawker targeted possible stratiform copper-gold mineralisation in dolomitic sediments, as at Martins Well and Willippa Dome, and cobalt-nickel(-copper)...

Mapping in the vicinity of the Warrakimbo mine and Rainy Day prospect, approximately 30 km west of Hawker, has indicated that altered dolomitic members of the Etina Formation are the most prospective hosts for specular haematite mineralisation, which...

Isolated old workings evidence the presence of small pockets of both galena and polysphaerite (lead phosphate) developed along a strong N-S trending fault zone, which radiates from a small circular diapir lying to the north of the Blinman Diapir. A...

An area centred approximately 70 km north-east of Hawker has been explored by E-Z for possible economic stratabound lead-zinc deposits. The company's evaluation of the results of base metal exploration carried out previously in the Flinders Ranges had...

A new deposit of massive, specular micaceous haematite, found associated with Neoproterozoic diapiric thrust faults and with hydrothermally recrystallised calcarenite members of the Etina Formation, was mapped at the Rainy Day prospect, which is...

Exploration for possible economic carbonate sediment-hosted Carlin style hydrothermal gold and copper mineralisation in the Mount Stuart - Patawarta Gap area of the Flinders Ranges has comprised soil, rock chip and stream sediment sampling, the...

Possible intrusive Proterozoic salt bodies beneath the Blinman, Upalinna, Martins Well, Mt Hemming, Willippa and Bibliando Domes were investigated by field mapping, including the construction of measured outcrop stratigraphic sections, seismic...

The Third Plain zinc silicate (willemite) deposit, located 14 miles south-east of Blinman, has been newly assessed by North Flinders Mines for its economic potential. Originally discovered by Kennecott Explorations in late 1966, and evaluated by them...

Exploration for possible hydrothermal/stratabound replacement-type base metal deposits in an area located 28 miles north-east of Hawker, adjacent to the northern margin of the Worumba Diapir, has consisted of photogeological mapping of structures...

After conducting a thorough evaluation and gap analysis of the past exploration carried out on the Blinman Dome and environs, the licence operator decided to carry out regional stream sediment sampling (1000 samples taken over 60 square miles) in the...

Inspection of an extensively faulted domal area within upper Adelaidean metasediments east and south-east of Martins Well Homestead sought to find barite deposits of sufficiently high grade and quantity to resemble those of the Oraparinna mine area,...

Reconnaisance and detailed geochemical surveys, plus limited diamond drilling at the Baratta mine (2 holes for 480 feet), failed to find any extensions to known but worked-out near surface Cu-Pb-Zn lodes. It was concluded that only a small area...
