This report describes a geophysical test survey made in September 1952, at the request of the Queensland Department of Mines and Mines Exploration Pty. Ltd., over an area measuring 750 feet by 1,000 feet in the Liontown area, about 28 miles south-west of Charters Towers, Queensland. The existence of a lead lode was known, because of its exposure in some inclined shafts, and this test survey was made to determine if the geophysical methods used could locate the exact position of the known lode, the ultimate object being, if the test survey were successful, to extend the investigations over a greater area. Self-potential and electromagnetic methods were used. A fairly strong indication, with an easterly strike, was recorded by the electromagnetic method at a position coinciding with the known lode, but no clear anomaly was recorded there by the self-potential survey. An even stronger electromagnetic anomaly, also with an easterly strike, was recorded about 300 feet south of the known lode, and was continuous from one end of the surveyed area to the other. The only self-potential anomaly of any importance was recorded between the two electromagnetic indications and is probably due to a quartz reef with pyrite mineralisation. The results show that the test was successful, in that the known lead lode was clearly indicated, and it is recommended that the survey be extended over a greater area to determine the full extent of the mineralisation. A target for a diamond drill-hole is also suggested, to determine the cause of the high electrical conductivity in the southern part of the area.
