Abstract

The Wallaroo-Moonta copper field offers a challenge to modern geological and geophysical ore-finding methods. After the production of some 338,066 tons of copper valued at over 20 million pounds, large scale mining ceased in 1923. In spite of the present urgent need for copper, investigators have agreed that no good purpose can be served by re-opening the old mines and that any further substantial production from the field depends upon the discovery of new ore-bodies. Since the ore-bearing rocks are almost completely covered by superficial deposits, it is not unreasonable to suppose that there are still undiscovered ore-bodies in the field. Nevertheless some 30,000 feet of diamond drilling have been carried out in the past and the results, generally speaking, have been very poor. This is not surprising, perhaps, when the local nature of ore occurrences and the vast extent of barren country rock is contemplated. It appears that there is a clear task for geological and geophysical methods to select sites where diamond drilling will have the maximum chance of intersecting ore. The masking of the surface geology immediately suggests the application of geophysical methods and in 1929 some work was carried out at Moonta by the Imperial Geophysical experimental Survey. After a limited amount of work this Survey was forced to the conclusion that the field presented greater difficulties to electrical prospecting, owing principally to the screening effect of the saline overburden. Since 1929, however, geophysical technique has progressed considerably, and more is known concerning the physical conditions of the field. In view of the possible prize at stake it was therefore decided early this year to re-open and carry out further geophysical surveys. The work was carried out in close co-operation with the South Australian Mines Department, which had previously made extensive investigations of the structural geology, and had recommended the use of the geophysical methods.
