The Bookartoo ochre mine, which lies 19 km south-east of Parachilna on the western face of the Heysen Range, for centuries has been a traditional and important source of quality ceremonial decorative pigment for the aborigines of central and eastern...

Flotation tests requested by Nairne Pyrites Ltd. were carried out using two different alkaline pH regulators and ammonium sulphate to activate depressed sulphides did not give results any better than those obtained normally. In some cases excess...

Nairne Pyrites Ltd reported that, when ore drawn from a recently developed area of the open cut was fed to the mill, a serious reduction in metallurgical efficiency occurred. A request was made that laboratory investigations be conducted to determine...

This report gives details of laboratory scale batch flotation tests carried out on pyritic ore supplied by Nairne pyrites Ltd. The work was carried out at Nairne, the object being to check the effect on flotation efficiency of variations in reagent...

Laboratory tests on two samples of pitchblende gravity concentrates received from South Alligator Uranium N.L. and assaying 50 percent U308, show that the material can be further upgraded to 70 percent U306 by removal of iron pyrite by flotation; the...

Tests carried out on ore supplied by Nairne Pyrites Limited showed that the Fortisol series reagents can be used to replace secondary butyl xanthate and/or Flotation Oil 66.

Sulfide and oxide trace element geochemical analyses have been conducted on more than 290 core chip samples collected from stored drill cores of 39 drillholes located across South Australia, as part of a collaborative project being conducted between...

In recognition of the centenary of Henry Yorke Lyell Brown's appointment as the first Government Geologist for South Australia, and the foundation of the Department of Mines and Energy, aspects of South Australia's colourful and vital mining and...

Expert inspection, by a government geologist, of the recently drained lower workings within the Spring Creek copper mine, below the entry adit level, has confirmed a previously expressed Chief Inspector of Mines' opinion that the wide working face...

Approximately 1000 geochemical drainage samples have been collected in two areas within the Stirling - Clarendon project area. Twelve square miles have been sampled in the Lenswood area at an average density of 27 samples to the square mile, and 26...

In August 1966, a request for assistance with conducting pyritic sulphur exploration in the vicinity of Brukunga was received by the SA Department of Mines from Nairne Pyrites Pty Ltd. Brukunga is 29 miles east of Adelaide by road and 3.5 miles north...

Diamond drilling at the Almanda Mine was continued with the completion of holes DAL 3 and 4, to depths of 187.45 and 104.37m. Both holes passed through the main east-west shear zone in siltstone/shale, but did not encounter the Stonyfell Quartzite. No...

Five hundred drainage geochemical samples were collected in an area of 16½ square miles over the Mount Grainger Diapir and surrounding country rock, during February and March 1963. Results of this survey outlined an extensive copper, lead, zinc...

The Balhannah Mine situated on Section 4048, Hundred of Onkaparinga produced 9 tons of bismuth and 170 tons of copper during the period 1869-1875. Subsequent exploration during 1881, 1889, 1936 and 1949 did not locate additional ore. The present...

Oxidized copper minerals and molybdenite occur in quartz veins cutting sericitized granodiorite 2 miles (3km) east of Bendigo Homestead. Coincident copper soil and I.P. anomalies were tested by drilling. A zone of probable secondary copper,...

Two 300m deep diamond drill holes tested an induced polarisation anomaly at the Bendigo prospect. The holes intersected weakly sericitised granodiorite carrying minor sulphide mineralisation, mainly pyrite, in narrow quartz veins. The average metal...

A band of basic granulite occupying the nose of a syncline in a folded sequence of predominantly acid gneisses was examined by detailed mapping, geochemical sampling, induced polarization and both rotary-percussion and diamond drilling. Primary...
