Exploration for diamonds and also for possible ultramafic igneous intrusion - related base metal mineralisation is being conducted in the area surrounding the small Permo-Triassic fluvioglacial sedimentary basin at Springfield in the southern Flinders...

EL 2603 is prospective for gold, base metals and diamonds. Regional studies and diamond exploration in the Nackara Arc region of South Australia demonstrate that it is a favourable tectonic environment similar to that of the AK 1 diamond pipe in the...

The Mt Caroline exploration licence is in the eastern part of the Musgraves Province in northern South Australia, approximately 300 km southwest of Alice Springs within the Anangu Pitjantjatjara Yankunytjatjara (APY) Lands. The tenement is comprised...

An area comprising two sub-blocks centred ~24 km north-west of Carrieton in the southern Flinders Ranges has been explored for possible buried diamondiferous kimberlite intrusions. The only work undertaken on EL 4184 was the acquisition of 10 small...

In continuing exploration for possible buried economic kimberlite diamond deposits that may have been intruded into Mesozoic and older basement and later become weathered out into cover sediments located along the western faulted margin of the Peake...

Work said to have been completed during the 2011 reporting period included an inspection and limited sampling of retained historic Utah drill cores from the Copper Claim area, checking of the preliminary resource estimates made by Utah from its drill...

Investigations of the likely diamond potential of a part of the central Eyre Peninsula were conducted under a farm-in joint venture agreement which was in place for about fifteen months. Work comprised the collection of six drill cuttings bulk...

Intensive surface sampling of mineralogical anomalies associated with possible buried intrusive plugs in the Mount Christie region has recovered one only small diamond, now interpreted as a false source indicator and probably due to laboratory...

Seven 25 kg stream sediment samples were obtained for detailed heavy mineral studies as part of a search for the source of a nearby palaeoplacer diamond deposit, which has only recently been discovered in Triassic basal conglomerates deposited within...

Exploration which aimed to test the base of the Neoproterozoic Tapley Hill Formation for economic sedimentary copper deposits has included 10 rotary drillholes (total 1731.8 m), notably with a successful intersection of 1 metre of chalcocite - bearing...

Diamond exploration undertaken about 80 km south of Coober Pedy comprised a helicopter geological reconnaissance and collection of 8 bulk loam samples for heavy mineral analysis. No kimberlitic indicator minerals were recorded.

Stockdale's diamond exploration work included reconnaissance stream sampling, and photogeology and Landsat interpretation. Ground magnetic surveys were run over aeromagnetic anomalies interpreted from the previous nickel exploration (Mount Purvis)...

TARGET: Buried possible Olympic Dam - type mineralization, and massive iron ore mineralization, in the Balta Baltana Creek area; possible diamond-bearing kimberlite rocks on Engenina. EXPLORATION: Aeromagnetic surveys were flown with follow-up ground...

An integrated regional exploration programme, including heavy mineral sampling, air photointerpretation, multi-element analysis of sample concentrates, and aeromagnetic/radiometric survey acquisition plus data interpretation, has shown diamond...

No potential kimberlites indicated.

In a search for possible buried kimberlite intrusions that may source authenticated historical diamond finds at the Echunga gold diggings, CRAE drilled 3 vertical percussion holes (total penetration 288 m) on 3 selected magnetic anomalies out of 30...

Ground magnetic surveys of possible diatreme localities, and gravel and soil sampling of selected heavy mineral trap sites in Quaternary alluvium, were undertaken in a search for diamonds north of Orroroo, in an area of unusual curvilinear...

A block comprising 727 square km or ~44.5% of EL 1003, being most of its northern portion, has now been relinquished due to its perceived diminished prospectivity for sedimentary copper mineralisation or diamonds. 11 percussion holes which were...
