Three prospects and two prospects covered by 16 claims were inspected in company of the claimholder. Small quantities of uneconomic mineralisation were found. Mr Robertson's mineral collection was examined and two specimens described.

Diamond drilling of the Mount Christie ironstone deposit has shown that three main ore types exist in it. At the request of the SA Department of Mines, drill core samples from hole CD1 were combined to produce three composite samples representing the...

Magnetic separation was carried out on a sample of titaniferous hematite to produce a concentrate for chlorination and direct reduction tests. A concentrate containing 81.7 per cent Fe203 and 6.35 per cent Ti02 was produced.

Two magnetite-martite deposits occur in Archaean metamorphic on Section 85, Hundred Myponga. The smaller (south-western) occurrence consists of scattered float and is on no economic significance. The larger (eastern) occurrence contains about 50,000...

An inspection of a mineral claim situated on a deposit of ironstone in allotment 759 (Section 1735), Hundred Moorooroo, 1½ miles westerly from Penrice was made on August 9th, 1961. The claimholders, Messrs. H.E. Heppner and M. Kuchel are seeking an...

Beneficiation tests on drill core samples from the two major zones of the deposit produced results similar to those obtained from earlier work on a surface sample. The grade of the samples was made lower than that previously investigated. Magnetic...

Following aerial ground geophysics reconnaissance drilling of 2 zones had intersected iron formation over 5.5 miles EW, 600'-1000' Ns and to depths of 850'. The formaiton appears to average 25% iron oxide, is relativley course grained and Davis Tube...

Analysis of the Corunna and Roopena one-mile sheets and plotting of structures subsequently recognised shows that the Iron Monarch area is a centre of radial structures. The structures and their arrangement are probably caused by upward vertical point...

Australia imports annually approximately 2000 tons of red iron oxide which is used as a pigment in the paint, rubber, linolem and building industries. Previous laboratory testwork on an iron ore from Malcolm Creek had shown that a hematite flotation...

Following aerial and ground geophysics and detailed geological mapping reconnaissance drilling at five potential ore zones has indicated 8.7M tons with a maximum possibility of 17.8M tons/100 vertical feet assaying 25% Fe or better. Preliminary tests...

The testing of iron ores for beneficiation by magnetic separation is normally done in laboratory separators of various types and the results are reported in terms of the variables, such as magnet coil current, rotor speed and gap width, of the...

Ten ground magnetic and gravity traverses delineated the Carrow Anomaly. Seven drillholes disclosed iron formation up to 200 ft. wide. Assuming a stike length of 3000 ft., reserves could approach 6 million tonnes per 100 ft. assaying 23.0 - 28.6%...

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...
