An area of high country in the far northern Mount Lofty Ranges was taken under licence to try to find the primary source(s) of widely dispersed detrital gold known from Recent and Tertiary cover sediments in the region, while focussing mainly on...

A licence area consisting of two separate sub-blocks that cover ~460 square km of Palaeoproterozoic BIF ironstone outcrops in the northern and southern parts of the Middleback Range on north-eastern Eyre Peninsula was taken up by The Broken Hill Pty...

The subject quarterly reports record primarily the progress and results of surface and underground exploratory drilling designed to define the Olympic Dam orebody. Further brief comments are provided about the establishment of mining and mineral...

A version of the Russian-invented CHIM electro-geochemical prospecting technique, which has lately been developed at Guilin University, China, was trialled in field surveys conducted at the Challenger gold mine, and at the Kalkaroo Cu-Au-Mo and Goulds...

This report is Phase 1 of a management plan for the former Port Pirie Uranium Treatment Plant site, and is essentially a preliminary investigation to establish a greater understanding of the characteristics of the site. Phase 2 will follow on from...

A version of the CHIM electro-geochemical prospecting technique that has been developed at Guilin University, China, was trialled in South Australia during August 2007 in field surveys conducted at the Challenger gold mine, at the Tunkillia gold...

The Brukunga mine site is a former open pit iron sulfide mine that continues to contribute to Acid and Metalliferous Drainage (AMD) into downstream waterways. Mine-based sources of AMD include the waste rock dumps and tailings storage facility. In...

An investigation has been conducted into the leaching of Crocker Well ore concentrates and the recovery of uranium and thorium from the leach liquor. Approximately 90% of the uranium and 80% of the thorium can be extracted from the concentrates by hot...

Newly acquired ground magnetic, mobile metal ion partial leach and conventional soil geochemical data do not support a possible kimberlite origin for an observed linear suite of small circular aeromagnetic anomalies occurring along the western margin...

Tailings remaining after the crushing/acidic leach treatment of uranium-bearing davidite ore from the Radium Hill mine, which are held in six clay-lined containment ponds ('dams') at the now disused Port Pirie ore treatment plant, have been studied to...

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...

3 samples were investigated. These contained malachite, chrysocolla and atacamite in siliceous gangue with some calcite. Copper from Mount Gunson is amenable to sulphuric acid leaching to dissolve copper. About 90% of the copper was extracted from...

Reports detail a field examination, a history of production and exploration, a mining resumption economic assessment, and negotiations with Jervois Sulphates (NT) Ltd. Austminex commenced its involvement in mineral exploration of the Stuart Shelf...

Report details engineering designs, drawings and costings for a new commercial scale leaching plant intended by E-Z to treat 70,000 tons/year of its crushed Beltana willemite ore having an average feed grade of about 40% Zn. The enriched, dissolved...

Geological mapping and the interpretation of drillhole data from the vicinity of the recently defined Southern orebody extension at Beltana (including 4 new diamond holes totalling 1600 feet) has enabled the licensee to formulate likely parameters of...

When Samin Ltd decided in 1969 to re-open the Burra mine for open pit extraction and onsite processing of the substantial remnant orebody of oxidised copper minerals, it was initially envisaged that the copper recovery method would involve an acid...

Ongoing exploration of abandoned historic mine workings and the surrounding area at the Mountain of Light prospect, located approximately 2 miles east of Copley, was aimed at delineating an economic copper oxide/carbonate - mineralised orebody and any...

Investigation of some isolated coarse-grained jaspilite outcrops and likely intervening subcrop, in an area 12 miles west of Iron Baron near the Middleback Range, sought to identify a currently economic iron ore resource of more than 60 Mt existing...
