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 ground geophysics reconnaissance drilling of 2 zones had intersected iron formation over 5.5 miles EW, 600'-1000' Ns and to depths of 850'. The formaiton appears to average 25% iron oxide, is relativley course grained and Davis Tube...

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...

This report outlines an attempt to ascertain the cause of a magnetic anomaly occurring on Archaean rocks, and the occurrence of any associated mineralisation. The investigation included a general study of the surface geology of the area, rock chip...

The author spent eleven months in the United States of America (September 1963 to July 1964) as an exchange visitor. He was engaged as party leader on a deep resistivity study of the earth's crust in Orogon and Washington States. The work was later...

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%...

A ground magnetic survey was carried out over an aeromagnetic anomaly to measure the vertical component of the earth's field. The results are presented as profiles and contours and a site proposed for a diamond drill hole on the basis of the...

Drilling results confirm the general synclinal structure. The jaspilite complex appears to be too low grade, too deeply weathered and too narrow to be of immediate economic interest. The western flank and main synclinal axis need more exploration for...

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 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...

Two diamond drillholes were completed over the period January to July 1963 in the initial stages of investigation of the Dawesley aeromagnetic anomaly, aiming mainly to test two IP anomalies 1 mile apart that had been detected on SADM grid line 1000...

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...

A gravity trough extending southerly from Lake Torrens suggests a possible subsurface escape route for brines from Lake Torrens. It is recommended that this gravity trough be drilled, however this recommendation may be modified by later seismic...

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...
