TARGET: Possible diamondiferous kimberlites subcropping under Cainozoic cover in an area located 110 km north-east of Glendambo. EXPLORATION: Acquisition and interpretation of 6759 line km of airborne magnetic and radiometric surveys, regolith heavy...

This report reviews the available information on the region and presents a preliminary appraisal of the past nickel exploration data supplied by South Western Mining Co. Ltd. Current field and laboratory information has also been included. The study...

'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...

A small area located approximately 20 km north-northwest of Orroroo was taken up to explore for possible diamondiferous kimberlite intrusions. Three known kimberlite dykes, one of which is diamondiferous, trend in a north-westerly direction through...

Diamond exploration undertaken within the southern of two adjoining licence areas taken up along part of the western flank of the Peake and Denison Ranges, that is centred ~100 km south-east of Oodnadatta, was aimed at discovering the source(s) of...

During a search for possible diamondiferous rocks within an area lying to the north of William Creek and abutting the south-eastern side of the Peake and Denison Ranges, stream sediment sampling and a low level, 5300 line km aeromagnetic / radiometric...

As part of a search for possible alluvial diamonds, within gravels of probable Tertiary age which may have been derived from a nearby area known to contain kimberlitic rocks, 4 stream sediment samples and 7 bulk samples were taken and processed to...

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...

A buried dipolar kimberlite target was detected west of Woomera by aeromagnetic and ground magnetic surveys. Sampling of surface gravels for diamond indicators and microdiamonds proved inconclusive. Aircore drilling (2 holes, total 143 m) identified...

Diamond exploration which was undertaken across practically the whole of Kangaroo Island, barring national and conservation parks and reserves, sought to test the potential of the island to contain kimberlite pipes and / or associated rock types, and...

Airborne magnetic / radiometric and EM surveys conducted west of Woomera did not reveal any promising diamondiferous kimberlite targets, and stream sediment and soil sampling carried out over a resultant uranium / potassium anomaly revealed no...

Exploration for diamonds, undertaken in an area centred 60 km east-northeast of Lyndhurst which had not been searched for this commodity previously, comprised the acquisition of aeromagnetic/radiometric and helimag surveys, and gravel and loam...

Diamond and base metal exploration carried out north-east of Marla comprised gravel, soil and rock sampling, helicopter and ground magnetometry, RC drilling (7 holes, total 647 m) and an airborne EM survey. Chromite anomalies were located in the...

A single dodecahedral 0.375 mm x 0.3 mm microdiamond and several different kimberlitic indicator minerals were recovered during regional stream sediment and gravel sampling of an area surrounding and extending south-west of Hawker. Follow-up...

Investigation of interpreted aeromagnetic anomalies located north-east of Moolawatana, in an area with previously recorded stream sediment chromite, comprised a ground magnetic survey and aircore drilling (3 holes, total 261 m). Two of the holes were...

CRA's acquisition and interpretation of aeromagnetic and ground magnetic surveys, plus its gravel and stream sediment sampling, have successfully located a few kimberlites in the Truro area, 70 km north-east of Adelaide, where a large number of...

Diamond exploration undertaken north-east of Marla, near Vernon Hill, comprised helimag and ground magnetic surveys plus drainage sampling. Magnetic sources were indicated at depths exceeding 200 m. One magnetic target was tested by a 117 m deep RC...
