Haematite quartzite occurs as a thin bedded formation in the Archaen metasediments of eastern Eyre Peninsula and have been traced intermittently from the Middleback Ranges, near Mangale, west of Tumby Bay, near Koppio southwards to west of Port...

One of the magnetic anomalies noticed in the aerial magnetic survey of the Maitland Military Sheet has now been investigated in some detail. A preliminary ground reconnaissance disclosed the presence of two large magnetic anomalies in the vicinity of...

This report summarises regional geology and the results of geophysical surveys and drilling. Ultrabasic rocks underlie the centres for each aeromagnetic anomaly and are sufficiently dense to account for each gravity survey. Spectrographic analyses do...

Sturtian glacial sediments south of Yunta contain haematitic and magnetitic siltstones (banded iron formation) and haematitic and magnetitic tillites formed by chemical deposition of magnetite euhedra in a finer grained haematite groundmass. Both...

As part of the SADM iron exploration programme in South Australia, geophysical and drilling investigations have been undertaken on the Warramboo Anomaly, the largest elongate asymmetrical aeromagnetic anomaly in the State outside of the Middleback...

The accompanying resume of current knowledge of ironstone deposits in the Central Province has been prepared for general distribution. It is based on recent field work, and supersedes that previously recorded by the writer in Summary Report, RB...

The initial test programme at Warramboo has been completed after drilling 13,163 feet. Techniques have been developed for drilling, sampling, and logging the materials encountered. The majority of holes intersected granitised metasediments...

From a preliminary investigation in an area of Proterozoic Sturtian series rocks 7 miles North East of Radium Hill there appears in excess, both quartzite and ironstone, of the 75000 cubic yards of crushed aggregate required for construction purposes...

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 submission of ironstone samples for examination by Mr. H.V. Clark the department requested precise locality information to enable a field examination to be made. An inspection was carried out by G.R. Heath, Geologist, and the writer on 7th...

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...

Kaditcha Rock and "Helene Reef" are discontinuous olongated craggy hillocks of ferruginous Wilpena Group sandstone and chart on the southern limb of a north east trending syncline. Outcrops are too small, and grade too low to be of economic interest...

The major structure is thought to be a north plunging syncline, the east limb of which has been folded into lesser anticlines and synclines. North plunging anticlines are though to flank this syncline. Grade of jaspilite in the syncline could...

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%...

Following geological mapping of a keel structure in iron formation and a gravity survey, two diamond drill holes tested the west limb and the core of the structure. The first (D.D.2) penetrated 2 ft. 6 in. of haematite in a leached zone adjacent to a...
