Bedded deposits of magnesite known to exist within the southern Flinders Ranges, where they outcrop over a considerable strike distance extent in the country approximately 20 km east of Port Pirie, were identified by Magnesium Developments Limited...

Magnesite beds formed within the Late Proterozoic Skillogalee Dolomite were the targets of exploration in the southern Flinders Ranges, 15 km east of Port Pirie. Field mapping and sampling, together with the acquisition and image processing of an...

Outcrop and drill core samples of magnesite-rich strata obtained from the Myrtle Springs and Witchelina deposits were examined petrographically to characterise the mode of occurrence and sedimentary history of the contained magnesitic material. A...

Known magnesite beds existing within the Adelaidean Skillogalee Dolomite in the far north-western Flinders Ranges, and extending into the Willouran Ranges over a strike distance of 120 km heading north-westwards from Leigh Creek South township, have...

Talc occurs in the Mount Fitton area in a massive recrystallized dolomite of Proterozoic age. The larger talc deposits are concentrated on its margins. This massive dolomite cuts through bedding and formation boundaries, and available evidence...

Talc has been mined at Mount Fitton in the northern Flinders Ranges on a continuous basis since 1945, for industrial use in the manufacture of cosmetics, ceramics and refractory ware. From 1979 to 1996, under authority of a series of Exploration...

Known magnesite beds within the Adelaidean Skillogalee Dolomite were the targets of exploration in the southern Flinders Ranges, 20 km north-east of Port Pirie, to determine their viability for mining as potential feedstock for a planned magnesium...

For earlier reports on its base metal exploration that were submitted by BHP Minerals covering the three licence reporting years 4/8/1995-3/8/1998, see the separate index record for Env 09983. Exploration undertaken within a large licence area...

Exploration Licence (EL) 2570 Mt Parry was granted to Magnesium Developments Limited on the 4 January 1999. Exploration within EL 2570 focussed on magnesite (MgCO3), which occurs within a sequence of interbeds with the Neoproterozoic, Skillogalee...

An area located in the south and central Willouran Ranges, and centred ~45 km south-west of Marree, has been explored for possible buried economic Neoproterozoic stratiform copper mineralisation and inferred MVT, replacement or diapir-related other...

A small area located on the inland side of The Coorong, midway between Salt Creek and Chinaman Wells, has been explored for possible economic evaporitic deposits of dolomitic magnesite which can be used to supply local markets for carbonate minerals....

A known, undeveloped stratabound Neoproterozoic magnesite deposit at Witchelina, for which resources and reserves have historically been defined, has been taken up afresh in anticipation that a beneficiation procedure can be developed that will result...

An area of outcropping magnesite-bearing metasediments extending from 10 km west of to 55 km north-west of Leigh Creek township is being explored to re-assess its commercial potential for magnesia and magnesium metal production, following other...

EL 4729/6019, which extends along the Mount Norwest Range located west-northwest of Leigh Creek for a distance of 50 to 66 km from there, and surrounds the location of the historic large Witchelina magnesite deposit, is being explored for possible...

EL 4729, which extends along the Mount Norwest Range located west-northwest of Leigh Creek for a distance of 50 to 75 km, and surrounds the location of the historic large Witchelina magnesite deposit, is being explored for possible other economic...

TARGET: The Willouran Ranges south-west of Marree were investigated for possible Olympic Dam type base metal occurrences which might have formed within the Precambrian Callanna, Burra and Umberatana Group sediments, and the area was also concurrently...
