Two small deposits of white to pale-coloured claystone, discovered in creek banks located respectively 10.5 and 12 miles south of Manna Hill township, were inspected for the local station owners. It was found that the beds of clean claystone are very...

In February 1951, South Australian Barytes Limited became interested in this mine, held under claim by Reginald John Alfred Larsson and requested an inspection by Department of Mines officers. This request was repeated, and endorsed by Larsson in...

An occurrence of barite mineralisation located in the eastern valley wall of the River Torrens gorge, 16 miles east-northeast of Adelaide, which lies on freehold property and has been privately mined in the past, was inspected in order to gauge its...

Geological mapping of seven contiguous mineral claims at Golden Grove held by the SA Builders' and Contractors' Association revealed three areas of potential brick clay. A programme of test boring was carried out to define the deposits and obtain...

In reports of 1 September 1953 by L.W. Parkin and 11 February 1954 by F.E. Hughes it was recommended that, in view of the results obtained from drilling at the Inglewood prospect, further trenching and drilling in Sections 5555 and 5556, Hundred of...

Recently modifications to existing borehole logging equipment have been carried out at Parkside Laboratories. In order to standardise borehole logging results and shorten the time delay in plotting, certain alterations in procedure have been...

In order to standardise borehole logging results and shorten the time delay in plotting, alterations in procedure and modification to equipment have recently been made. Arrangements have been made with the Boring Branch and the Officer-in-charge at...

An unsucessful attempt has been made, by gravity and magnetic methods, to locate the presumed extension of a fault in Adelaide System rocks near Kapunda.

Three gravity traverses have been measured over the Katunga Hills in order to investigate the similarity of the gravity anomaly over them to an anomaly of magnitude 6 mGal just north of Iron Knob. An anomaly of magnitude 3-4 mGal was found centred on...

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...

Ten diamond drill holes were drilled to assess the reserves available for quarrying at the Roadside (Maralinga) Quarry and to test its suitability for concrete and road aggregate. Drilling revealed dolomite reserves of 190,000 cubic yards. Large...

Results are reported of laboratory firing tests made on 11 shale samples and 4 clay samples, performed in both oxidising and reducing furnace atmospheres for various length heating periods over an extensive fusion temperature range. The bloating...

An inspection of an occurrence of talc situated in Section 228, Hundred of Jellicoe, 3¼ miles northeast of Truro, was made on 12/10/1960. The deposit was first noted by D. King (Mining Review 103, 1957, pp. 68-69) when a borehole showed about 4 feet...

The results of this investigation show a small gravity "low" over the structure suggesting that the rock formations beneath the central portion of the Dome are less dense than those comprising the surrounding area. No significant magnetic variations...

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...
