Uranium mineralisation was first discovered at the old Shamrock Copper Mine during a systematic search of old mine dumps by the South Australian Department of Mines in 1955. Follow-up investigations located a small high-grade uranium lode (Valley...

Base metal exploration activities undertaken by Thiess Brothers in the Yumali - Coomandook area investigated several coincident regional gravity and aeromagnetic anomalies arising from concealed Palaeozoic basement rocks. These anomalies are part of a...

Sediments including basalt and limestone of late Pleistocene-early Pliocene age occur on Mount Graham. Both these rock types are considered suitable material for crushing for use as road metal. Reserves of basalt are estimated to be between...

Wilgena 1 (TD 973 m) penetrated 964 m into Tarcoola Formation within the Wilgena Sub-basin, without encountering magnetic basement. Thin dacitic to basaltic tuffs and basaltic flows, interbedded with carbonaceous siltstones, indicate contemporaneous...

This discordant dyke related to kimberlite and carbonatite intrusions has been emplaced at a low temperature into Umberatana Group shales and siltstones. Its composition is unsuitable for use in manufacturing glass and ceramics due to both low...

Rocks from Saint Francis Island include trachyte, trachyandesite and rhyolite. Drill core from Dampier DDH1 includes 2 types of dolerite, and from Afmeco KGB3 fresh dolerite or basalt. Other specimens examined include basalt and gneiss from the...

The SADM stratigraphic hole Roopena DDH1 was originally drilled near Roopena homestead in 1967 to TD 155.61 m, and was deepened to TD 249.59 m by SADME in 1978 (as DDH1a) to obtain relationships between the Roopena Volcanics and older units. At...

Reserves of 151 tonnes of basalt are inferred.

Since 1950, 75 000 tonnes of fine grained, columnar jointed Wisanger Basalt have been quarried, 3 km NW of Kingscote. It is the only aggregate quarry with a crushing plant on K.I, and produces a large range of products. Indicated reserves are 370 000...

The wholly cored SADME DDH Myall Creek RC1 was sited at the eastern extremity of the exposed Gawler Range Volcanics, and was completed [as a vertical hole] at 551.34 m total depth [the limit of drilling rig capability] on 26/10/1978, without reaching...

SADME Nanyah 1 (hole synonym M154), a Murray Basin hydrogeological observation bore, was extended beneath the sedimentary cover to reach basement in order to investigate the source of a prominent aeromagnetic anomaly. A 3-metre bottomhole core of...

A trachyandesite from the Gawler Range Volcanics at Buckleboo and an alkali basalt from the main quarry at Mount Schank are suitable for Departmental geochemical standards. A sample from an outcrop of Heatherdale Shale at Carrickalinga Head is a...

Rocks which in the field appear to be emplaced as dykes or lava flows have been found to be altered and weathered, and include metasediments and laterites or gossans. Rocks of probable igneous origin include basaltic and doleritic types. Only one...

Maximus Resources' Billa Kalina Project area lies within the Olympic Dam Province of the Gawler Craton, where the basement rocks host Olympic Dam, one of the largest iron oxide-associated copper-gold (IOCG) deposits in the world. IOCG deposits are...

An area covering most of the northern outcropping Peake and Denison Ranges basement inliers was taken up by Pancontinental Mining to test for possible economic occurrences of lead-zinc and copper-gold mineralisation (broadly matching Mount Isa Block,...

During 2007-2008, the first year of the diamond exploration joint venture with the Filsell brothers in the Paratoo area, Flinders Mines' activities comprised: • acquiring part of a detailed helicopter-borne infill aerial magnetic ('helimag') survey,...

An area covering ground adjacent to the southern boundary of current EL 3056 (formerly EL 2483), on which licence the newly discovered (in November 2001) Prominent Hill IOCG deposit is situated, is being explored for similar style buried...
