Exploration for possible commercial diamond deposits has been carried out along a portion of the G2 gravity lineament located immediately south of William Creek and the southern Peake and Denison Ranges, looking for inferred diamondiferous kimberlite...

During the first year of combined reporting for exploration licence 2675 “Ediacara”, 2593 “Blinman’ and 2627 “Wilkawillina”, the exploration focus was primarily on the Ediacara tenement. During mid-1999, Perilya reviewed the Ediacara Mineral Field,...

As part of continuing diamond exploration on the subject five licences, more of the first pass sampling program was completed by Flinders Diamonds in August 2006 via aircore drilling of 47 vertical holes for an aggregate 1852 m aimed at penetrating to...

An area centred ~40 km east of Peterborough in the vicinity of Mount Grainger Goldfield has continued to be explored for possible small diamondiferous kimberlite bodies and for buried economic stratabound, structurally controlled and disseminated...

Base metal and gold exploration undertaken over a lengthy period since 1980 in the Yudnamutana Hill area, 20 km north-west of Arkaroola, has comprised detailed geological mapping of major basement and cover stratigraphic units and known mineral...

Following recognition of the likely young age of the sources of the Abminga area magnetic anomalies, and the discovery of a number of diamond indicator minerals in sediments to the west of the Peake and Denison Ranges, the Allandale joint venture...

Results of reconnaissance geochemical sampling of outcrop and lag gravels of ?Birksgate Complex ferruginous quartzites within the eastern Musgrave Block did not justify further exploration for potential Broken Hill-style exhalative Pb-Zn-Ag deposits.

Previous drilling by WMC at the Kartanya prospect, 30 km west of Rudall in the central-southern Eyre Peninsula, yielded several high grade Fe intersections with up to 1% P and 140 ppm Zn. Reassaying of drillhole samples returned reduced levels of...

Interpretation of available SADME/BMR airborne magnetic survey data, and subsequent ground magnetic and gravity surveys to define five targets, were conducted in the area between Watson Siding and Ooldea, prior to drilling two rotary percussion holes...

As part of a regional search for diamondiferous kimberlite, stream sediment sampling of ?54 sites in the Wharton Hill area failed to reveal any kimberlite indicator minerals. However, heavy mineral concentrates from samples taken at four sites in the...

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...

Recent company reconnaissance studies have shown the presence of anomalously high Ta and Nb in sodic granites in the Mount Painter area. Herein a preliminary account is given of the field relationships, petrology, geochemistry, mineral chemistry and...

Reconnaissance geological mapping of existing, previously quite productive opal workings in the White Hill area of the Stuart Range 'Breakaway' country, 100 km south-east of Coober Pedy, was followed by exploratory and infill narrow-hole auger deep...

Ground magnetic and gravity surveys were carried out over a south - southeast trending aeromagnetic feature located 20 km south-east of Naracoorte. It was concluded that drilling to depths of around 150 m would be required to test for the possible...

An area located 140 km north-west of Tarcoola was taken up to explore for possible economic high grade occurrences of palygorskite clays formed in Tertiary palaeochannels and associated playa lakes. This was a response to a discovery of palygorskite...

Calcrete sampling over aeromagnetic targets within the Fowler Shear Zone was undertaken, to locate evidence of possible Cu-Au mineralisation developed during emplacement of Hiltaba Suite granites south and south-west of Wynbring. Weakly anomalous Au...

The subject adjacent licence areas, located approximately 55 km north-northeast of Coober Pedy, were the first tenements taken out for regional opal exploration under the provisions of the newly proclaimed South Australian Opal Mining Act 1997. The...

A small licence area centred approximately 70 km north-northwest of Oodnadatta is being explored for possible economic buried IOCG type mineralisation that may have formed in the wholly concealed, almost unknown basement rocks there. Interest is...

35 surface samples of various clastic sediments deposited on Kangaroo Island were studied microscopically to see if the respective abundances, composition and mineralogical features of their heavy mineral grain components might shed light on possible...

Investigator Resources Limited (IVR) is continuing to explore its contiguous tenement package in the Southern Gawler Ranges for economic precious and base metals, following its discovery of the Paris silver deposit in 2011. A prospective region called...
