The area previously surveyed by SADM in the “Racecourse” area near Burra, using a 400 foot dipole-dipole configured induced polarisation spread, was resurveyed using a 200 foot dipole-dipole IP sensor configuration. This was done to obtain closer...

10 miles north-west of Tumby Bay, a syncline of jaspilite, with a shallow southerly plunge, could contain 8-13 million tons of magnetic iron ore per vertical 100 feet. Unweathered jaspilite with magnetite occurs. Assessment of the potential of the...

In September 1964 and June 1965 an exploratory survey found good hydrological – geophysical correlation for the sedimentary formations in Southern Yorke Peninsula. Further work is warranted to delimit the boundaries of the aquifers and the extent of...

In May 1965 an exploratory resistivity survey showed that geophysical - hydrogeological correlation of the sedimentary formations near Waikerie was possible. Further work at closer intervals is warranted.

Further electromagnetic and induced polarization work has been carried out in the Tarcoola Blocks mine and Brown Hill areas at Tarcoola to extend and substantiate previous investigations (ref. RB 59/128, 23 November 1964). The latest results...

A re-examination of the induced polarisation (I.P.) grids covering the Ediacara Mineral field clearly reveals that many of the reported anomalies are extremely doubtful, as they have been based upon insufficient data, incorrect presentation of data or...

Using an electromagnetic device, a series of traverses were surveyed in the immediate vicinity of the Dome Rock Copper Mine. Several anomalous areas were defined, some of which are considered worth further investigation.

The survey of Lower Yorke Peninsula was conducted between the 14th and 23rd February 1955 taking 25 hours flying time and covered the land areas of the one mile military sheets of Curramulka, Stansbury, Edithburg, Turton, Coonarie, Deberg and...

A ground magnetometer survey was carried out on section 134, Hundred of Cunningham, County Ferguson by the writer and B.E. Wilton, on the recommendation of L.S. Denholm. No significant magnetic anomalies were located suggesting the absence of...

A geophysical survey was carried out by the writer at Yalpara on the recommendation of A.R. Crawford (Geologist - Engineering and Mineral Resources Section). A base line running magnetic north and south (3000 feet long) was laid out by the writer and...

An airborne magnetometer complete with aircraft and crew was retained under contract to conduct surveys over selected areas within the state. A description is given of the equipment layout and of the procedure of reducing the results obtained.

Almost six weeks were spent with the Far North-West party at Granite Downs Station in conducting magnetic and gravity traverses. Work was curtailed before sufficient results could be obtained for an accurate picture of subsurface structure. Gravity...

Ground magnetometer surveys were carried out by the writer over typical portions of the geomagnetic anomalies located at the North Billeroo dam area and adjacent to the Alconie dam to determine their cause. Inspection of these areas showed that the...

A survey with gravity meter and vertical force variometer has been carried out on two aeromagnetic anomalies to the west of the Katunga Hills. The area is covered with sand and alluvium and results obtained indicate the anomalies to be due to varying...

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...

Four different types of geophysical surveys were carried out in the vicinity of the old Talisker Mine in an effort to detect the presence of possible sulphide ore bodies. No conclusive results were obtained due to the lack of penetration of the...

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

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...

An electromagnetic (EM) survey was carried out in the vicinity of the inactive Uley graphite mine in an effort to detect possible extensions of the known graphitic lodes with a view to developing additional open cut areas. Several zones of anomalous...
