An absolute age of 677 Ma +/- 12 Ma was determined from analyses of six selected zircon grains separated from the subject volcanic rock sample, but the result is strongly affected by the need to impose large corrections to the data to compensate for...

Initial exploration carried out near Lilydale Homestead, 80 kilometres south-east of Yunta, targeted possible Starra-style gold in the Braemar Ironstone facies. Flying of an airborne semi-detailed magnetic and radiometric survey identified magnetic...

Exploration for possible heavy mineral sand marine placer deposits within Tertiary sediments on the northern margin of the Murray Basin comprised aircore drilling (28 holes, total 744 m) in the Mutooroo station area, 50 km south-east of Olary. The...

The Curnamona Province is exposed in the Willyama, Mt Painter and Mt Babbage Inliers, but much is obscured by younger sedimentary cover. It comprises a late Palaeoproterozoic metasedimentary and metavolcanic succession (Willyama Supergroup) with some...

Significant exploration focussed on: · stratabound 'Telfer-style' gold in Adelaidean metasediments in the Nackara Arc, using stratiform or stratabound structurally-controlled genetic models; and structurally controlled gold and base metal...

266 summary sheets on significant lead-zinc occurrences and anomalous concentrations have been prepared by the Department's Lead-Zinc Taskforce as a data package, in the form of 5 reports, to assist in the search for lead-zinc deposits to provide...

An area centred ~50 km south west of Cockburn is being explored for possible economic base and precious metal mineralisation that may have formed in buried Palaeoproterozoic basement rocks, as well as for any secondary uranium mineralisation that may...

Half of a small licence area located in the Anabama district has lately been surrendered. The ground had been taken up to explore for possible economic buried base metal mineralisation that might have formed on and near the south-eastern margin of the...

A small area covering the eastern end of the historic Anabama copper prospect in the Benda Range south of Manna Hill has been explored for possible buried economic, epithermal/hydrothermal structurally controlled copper-gold mineralisation that may...

A very small area centred ~60 km south-east of Olary has been explored for possible economic buried Late Proterozoic sediment-hosted or volcanic hosted massive sulphide (VHMS) Cu (-Co) mineralisation. Previous exploration conducted by Longreach Metals...

Continuing exploration for possible hydrothermal or epithermal base metal and precious metal deposits, within an area centred 60 km south-west of Olary, at the outset targeted some previously identified geochemical anomalies, principally via shallow...

The target of exploration carried out in an area centred 65 km south of Olary was a possible large supergene occurrence of low grade gold-copper mineralisation within the felsic to intermediate Boucaut Volcanics. Selected samples from earlier drilled...

An area centred ~50 km south-east of Manna Hill township on the Barrier Highway was taken up to explore for possible economic buried epithermal, VHMS style copper-gold or other base and precious metal mineralisation which could have formed within...

Exploration for possible concealed volcanogenic massive sulphide (VHMS) base metal mineralisation associated with the Mesoproterozoic Boucaut Volcanics has included the acquisition and assaying of 1200 soil samples, traverse drilling of 224 shallow...

Newmont Mining used a ground magnetic survey, an IP survey and a soil geochemical survey to select sites at the Mutooroo Ridge copper prospect for its subsequent drilling during May and October 1977 of 2 inclined, percussion precollared diamond cored...

An area centred ~50 km south-east of Manna Hill township on the Barrier Highway has been taken up to explore for possible economic buried epithermal, VHMS style copper-gold or other base and precious metal mineralisation which could have formed within...

The Mingary 1:100 000 map area in the north-east of the state covers part of the Curnamona Province. Five suites of basic intrusives have been identified in the area. The most widespread is a series of amphibole-bearing sills which, having an...

RC drilling (22 holes, total 1322 m) was carried out at the historic Anabama and White Rock copper prospects, 60 km south-east of Mannahill. A resource of 4.2 Mt @ 0.52% Cu was inferred within an oxidised zone present above 80 m depth, but subsequent...
