The history of the project, tabulated geophysical results, summarised bore logs (KR's 1-11) with the grade of the iron formations intersected are recorded. Recommendations are made for further ground geophysics and drilling.

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...

A 410 lb sample of iron ore, labelled Malcolm Creek, was received. It was requested that the investigation should include crushing and sizing tests, Davis-tube tests, Humphreys-spiral tests and any other tests considered available.

The sample received was a banded quartz-iron oxide ore containing 43.1% acid-soluble iron. The main iron oxide mineral present was martitised magnetite, the effective grainsize of which ranged from 0.01 x 0.02 mm to 1.23 x 1.63 mm, the bulk of the...

Ground geophysics suggests that the major structure is an overturned anticline or syncline, closed to the east-northeast, and with the axial plane striking east-northeast - west-southwest and dipping steeply to the north. High magnetic and residual...

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...

Magnetic separation tests on natural and reduced feeds, Humphreys spiral tests and preliminary flotation tests were carried out in this investigation. Best results were obtained by magnetic concentration of the reduced ore, which produced a...

The high grade crabodies and the jaspilites of the Middleback Group Archaean (?) in the Middleback Ranges (Loc. 1) are the largest reserves if iron ore in South Australia. Most of the numerous deposits elsewhere in the State, especially the high grade...

Determination of the magnetic iron content of ores has normally been made by means of the Davis tube. Examination of a Billeroo iron ore, which contained a high proportion of martite, gave misleading results (a) (AMDL-175). This project was therefore...

A potential iron ore deposit has been investigated in the upper horizon of jaspilite beds of the Hutchison Group, where a drag fold has caused a thickening of the jaspilite beds. Surface samples average 42.2% acid soluble iron. The deposit has a...

Aeromagnetic anomalies mapped at Mount Woods and to the south were investigated for their iron ore potential by conducting a low-level aeromagnetic survey and by performing a geological reconnaissance and acquiring ground magnetic and gravity data....
