In a continuation of diamond and base metal exploration of newly discovered carbonatite / kimberlite intrusive bodies in an area located immediately north of Orroroo, these bodies were examined petrographically and analysed to compare their...

Diamond exploration undertaken over a much dissected 460 square km area of the south-central Flinders Ranges between Stirling North and Mount Arden comprised aeromagnetic interpretation and heavy mineral processing of a regional suite of 170+ stream...

During the period April 1st to July 14th 1964, the writer was privileged to visit overseas a number of important non-metallic mineral deposits including most of the world's major phosphate deposits. In the United States inspections were made of the...

An area situated immediately south-east of Elliston has been explored for diamonds, in conjunction with similar work being carried out by the joint venture on Flinders Island and on its adjoining Venus Bay, Colton and Polda mineral exploration...

Renewed diamond exploration has been conducted in a part of the western Eyre Peninsula where numerous kimberlite indicator mineral (KIM) anomalies occur in surficial sediments, and where the four adjoining licence areas involved lie in close proximity...

Older volcanic basalt outcrops in the north bank of Salt Creek 7 miles north of Dergholm (Section 42, Parish Dergholm, Victoria). Investigation of this olivine basalt flow with amygdules of zeolite, by surface mapping, auger and diamond drilling has...

Low grade, nickel bearing, weathered ultrabasic rocks that form a part of the Giles Complex in the North-West Province of South Australia were first discovered by a SA Mines Department field party in 1953. Since their discovery the weathered rocks,...

An extensive detailed and regional exploration programme was carried out in the North-west Province in 1965. Geological mapping, geophysical (gravity and aeromagnetic) traversing, and test drilling were undertaken to test known occurrences and...

'Industrial minerals' are those minerals or assemblages of minerals which are economically important because of their physical or chemical properties, rather than their metal or energy content. The term is synonymous with 'non-metallic minerals', and...

The Mount Toondina structure, a small but pronounced vertically fault-bounded inlier of Permian sediments within a flat-lying Mesozoic sequence, is represented by an annular magnetic feature located 45 km south of Oodnadatta. A single gravity profile...

The Gawler Craton has, for some time, been known to have potential for kimberlite discoveries. Recently, Orogenic Exploration Pty Ltd found a complete range of kimberlitic indicator minerals, and five small diamonds, on Flinders Island, about 40 km...

Exploration over the eastern flank of the Musgrave Block to the north of De Rose Hill, for potential buried Giles Complex layered intrusive bodies, comprised SAEI data interpretation, airborne magnetic, radiometric and electromagnetic surveys, ground...

Reconnaissance mapping and sampling of an area of poorly exposed Precambrian crystalline basement north of Kingoonya has shown that the regional geology is dominated by intensely folded, discontinuously outcropping banded iron formations that are...
