A small area of coarse haematite floaters were tested by scout boring to determine the origin of the haematite. The boring proved the material to be a scree deposit probably from an eroded ore body further up the slope to the north of Prospect No. 2.

At a cost of 0.9d. per ton, 27 percussion holes aggregating 2280 feet have disclosed 1 and a quarter million tons of limonite assaying possibly 50% Fe, 3% Mn, 9% Insolubles. Further ore occurs in the immediate vicinity and northerly in the Cooyerdoo...

In an area of limited basement outcrop located between 2 and 5 miles north-northwest of Iron Knob township, the Department's surface traverse channel sampling (969'), percussion boring (643’) and diamond drilling (1270’) tested a low grade...

The results of gravity and magnetic surveys over Prospect No. 5 display trends which can be interpreted in more than one way. From results of previous drilling, a number of small gravity anomalies appear to be associated with iron ore, which a larger...

The Radium Hill uranium mine is located approximately 60 miles S.W. of Broken Hill. The deposits are of hypogene metosomatic origin, and represent replacement lode deposits along anticlinal axial plane shears in folded Archean gneisses. Lode...

An uncompleted gravity survey over Prospect No. 6 suggests that there may be an association between the gravity anomalies and a massive limonite orebody. Further gravity work is recommended to enable greater confidence in interpretation.

A zone of limonite and haematite outcrops 4 miles long has been located on the lower south-western slopes of the North Middleback Range. Detailed mapping, drilling and costeaning have been completed by the Department to evaluate the area. The area has...

The following combined observations were made during a brief visit of inspection to the principal iron ore occurrences in Western Australia by the South Australian Director of Mines, Mr T.A. Barnes, Senior Geologist, Mr G.F. Whitten, and Mining...

Extensive deposits of medium-high grade stratiform iron ores occur in the Radium Hill area. Deposits readily amenable to open cut mining occur over large areas, in beds ranging to 60 feet in width and varying considerably in the content of...

Vertical magnetometer and gravity meter traverses have been run over anomalies disclosed by aeromagnetic surveys near Cowell on Eyre Peninsula. The presence of a very large quantity of magnetic rock, denser than the surrounding rocks and thus...

The use of ammonium nitrate mixed with carbon as an explosive has been pioneered in the United States of America. Advantages: The advantages are that ammonium nitrate can be freighted in bags by rail, truck, or ship similarly to superphosphate at much...

This report summaries the preliminary examination of the northeast area of the Braemar Ironstone Deposit. Nine detailed cross-sections have been prepared. Revised tonnage estimates for Razorback Ridge have been made, namely 109 million tons above...

A deposit of ironstone, reported on by R.K. Johns (D.M. 1183/55, G.S. 364) was inspected, further samples have been taken, and a section through the deposit has been drawn. No further action is recommended.

Two high grade hematite orebodies reported by R.L. Jack (Bulls, 3 and 9, Geological Survey of South Australia) were located and mapped on Section 5, Hundred of Campoona. Samples were taken for petrological examination and assay. No further action is...

The Sturtian iron formation in the Braemar – Manunda District, 30-40 miles south of Yunta, is being examined as a possible future source of iron ore. Iron occurs as matrix in tillite and as bedded magnetite-hematite-quartzite. One deposit known as...

This report lists deposits visited, summarises exploration techniques investigated and recommends briefly an iron ore exploration policy for the immediate future. It will be supplemented by later reports.

An outcrop of hematite quartzite reported by prospector Morley on Sections 17 and 19, Hundred Kelly, was inspected. Surface chip samples were taken for assay over 5 outcrops. No further action is recommended at this stage.

The heavy mineral fraction of an alluvial sand south of Moomba contains fine black magnetic grains. X-ray diffraction and electron probe analyses show that the magnetic grains have a hexagonal crystal structure intermediate between that of hematite...
