Drilling results confirm the general synclinal structure. The jaspilite complex appears to be too low grade, too deeply weathered and too narrow to be of immediate economic interest. The western flank and main synclinal axis need more exploration for...

A comparison of known iron deposits in Western Australia and South Australia suggests that large, high grade iron orebodies occur in flatly dipping favourable horizons which have a leached and oxidised appearance: siliceous, steeply dipping iron...

The major structure is probably an overturned north plunging anticline, the nose possibly containing 450 000 tons per vertical foot and averaging 45.8% iron. Preliminary tests at Australian Mineral Development Laboratories suggest that the ore may be...

Reconnaissance of ironstone quarries and iron formation outcrops revealed Archaean (?) and Upper Proterozoic (Sturtian) iron formation and laterites derived from them. These are easily distinguished on geological and aeromagnetic criteria. While a...

At the request of the South Australian Department of Mines a survey of current Australian usage of mineral fillers and pigments was made. The survey was intended to determine the consumptions and specifications typical of various industries and to...

This report is an economic appraisal of the viability of mining the low grade deposits of iron ore occurring in the Warramboo area (including Kopi and Kyancutta) and at Greenpatch. The former is located in central Eyre Peninsula, 123 miles by railway...

Jaspilite beds possibly containing 4 tons of ore averaging 37% Fe have been located at Charlton Gully, Jaspilite occurring on a hill in Section 4E, Hundred Wanilla could contain a possible 1.6M tons of ore averaging 44% Fe. As the latter is thought to...

Detailed geological mapping has identified a metamorphosed iron formation though to be equivalent to the Middleback Group of Eyre Peninsula. Four diamond drillholes have given complete intersections of the Mount Christie, Fingerpost Hill and George...

Irregular oxidised orebodies up to about 3 feet thick, containing copper carbonates, quartz, sphaerocobaltite (cobalt carbonate) and wad (hydrated manganese oxide), occupy both shear zones aligned parallel with bedding, and crush zones developed...

Copper carbonates are sporadically distributed throughout steeply dipping mica schist in a zone up to about 70 ft. wide. The host rocks have been regarded as overturned metamorphosed Burra Group (Torrensian) beds resting on the Aldgate Sandstone...

Steeply east-dipping jaspilite beds, with a thickness of between 200 feet and 400 feet, could contain 9 to 22 million tons per 100 vertical feet of coarse-grained, slightly magnetic iron oxides. Surface samples average 39.1 % acid soluble Fe....

Siliceous ironstone in Sec. 201, 3 miles west of Yongala, occurs as scattered lenses within sandy shale on the lower slopes of a hill and as a capping at the top. The scattered and irregular nature of the outcrops allows only the rough estimate of...

Magnetic separation, flotation concentration arid gravity concentration/size classification methods were tested for the beneficiation of Nairne-pyrite calcines. Magnetic separation following a reducing roast produced a concentrate assaying 62.1% Fe at...

Ironstone on Section 201, Hd. Mannanarie, near Yongala, was drilled and found to be only 3m thick. Reserves are thus very low. Limestone drilled to 15m on the neighbouring Stone Reserve gave a very poor core recovery, a reflection on the porous,...
