Ongoing exploration for Olympic Dam-style Cu-Au-U mineralisation, over an area centred ~15 km south-east of Arcoona Homestead, during this period comprised 3D geophysical modelling of possible source geometries for, and RC drilling (10 holes, total...

Exploration for Olympic Dam-style mineralisation, undertaken over an area centred ~15 km south-east of Arcoona Homestead on the Stuart Shelf, which includes WMC's formerly partly tested Emmie Bluff prospect, has comprised the acquisition of ground...

A representative selection of rock types obtained in the cores of the DDH1 and DDH2 iron ore exploration holes was made with a view to studying the mineralogy, the lithology and any microstructures of interest present in the formations intersected. A...

An inspection of the deposit was requested after a sample submitted by Mr Wood for identification proved to be magnetite inter grown with hematite (Petrological Report P 41/55 attached). The writer was accompanied by Mr Wood and Mr A.R. Crawford...

An aerial magnetometer survey carried out by the BMR in 1952, followed up by SADM during 1953 with detailed ground magnetometer surveys, revealed two prominent magnetic high anomalies located south of Balgowan on Yorke Peninsula (maximum recorded...

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...

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...

This project has been directed towards treating the low-grade ironstone constituting the Braemar Iron Formation. Report AMDL-111 dealt with the reduction by hydrogen of small solid cylinders of ironstone cut from surface samples. Report AMDL-189...

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...

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...

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%...

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.

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...

Geological mapping, on a scale of 1" represents 440 feet and sampling of Lower Marinoan and Upper Sturtian sediments was carried out as a result of anomalous aeromagnetic values occurring within the sections listed above. From surface investigations a...

A third diamond drill hole was completed to a depth of 175m at the Dawesley anomaly. It intersected micaceous siltstones, greywacke and schists of the Kanmantoo Group. No significant mineralisation was encountered.

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...
