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...

Detailed geological mapping has identified a metamorphosed iron formation though to be equivalent to the Middleback Group of Eyre Peninsula. Four diamond drillholes have given complete intersections of the Mount Christie, Fingerpost Hill and George...

The project followed a logical appraisal, from conducting high level aeromagnetics through low level aeromagnetics, ground geophysics, drilling and shaft sinking, to metallurgical testing. All geophysical methods used divide the anomaly into three...

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...

Supplementary gravimeter traverses have been run over the strong Bungalow aeromagnetic anomaly to further define it. Earlier in the year a percussion drilling programme was carried out over the same area. In the light of both sets of results it is...

Two angle diamond drillholes (totaling 1062 feet) were put down on a site of an anomaly detected during an aeromagnetic and ground magnetic survey. It was hoped that copper mineralisation may be located. A magnetic zone 80 feet wide and dipping 65...

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...

In an area of limited basement outcrop located between 2 and 5 miles north-northwest of Iron Knob township, the Department's surface traverse channel sampling (969'), percussion boring (643’) and diamond drilling (1270’) tested a low grade...

For a project to determine the base metal potential of known copper-mineralised igneous rocks which outcrop in an area located approximately 59 km south-west of Olary, the South Australian Government has completed detailed mapping, geochemical...

Following the acquisition and interpretation of 435 line km of ground magnetic surveys over selected aeromagnetic anomalies within regions of high magnetic relief on the northern Gawler Craton, 121 reverse circulation holes totalling 8609.25 m were...

As part of the South Australian Steel and Energy Project, MESA has explored several significant aeromagnetic anomalies to try to find a possible iron ore resource. The Sequoia, Wirrida and Gina magnetic anomalies were chosen as indicating...

Mines and Energy South Australia, as part of its contribution to the South Australian Steel and Energy Project, has defined an iron ore resource in the Coober Pedy region. Extensive ground magnetic, gravity and drilling programs identified four...

Economic deposits of iron-oxide associated copper-gold mineralisation of the Moonta-Wallaroo or Olympic Dam style, hosted in Palaeoproterozoic basement rocks of the Moonta Sub-domain, were targeted by exploration in three now surrendered licences,...

[ Note - here is Part 2 of the abstract relating to 2 separately indexed parts ]. A new joint venture with Barrick Gold, pertaining to the renewed (as EL 3424) tenement, was signed on 8/2/2007, after which that company as operator undertook a 749...

The main aim of Havilah Exploration's PACE Initiative Year 3 approved drilling programme was to test the east-west trending, quartz-veined breccia zone that passes through the central Kalkaroo Dome, specifically in the footwall of the Kalkaroo Cu-Au...

No field work was performed over a small licence area located approximately 40 km east-southeast of Tarcoola, where an E-W elongated intense magnetic anomaly corresponds to a low hill of outcropping banded iron formation with an eastwards extension...

Centrex Metals commenced reverse circulation exploration and resource definition drilling at the Wilgerup iron ore deposit on 6/9/2006, which was partly funded by the PACE Initiative as a Year 3 approved project, with funds allocated for 1000 m of RC...
