Uranium was produced as a bi-product of radium mining in South Australia at Radium Hill from 1906, and Mount Painter from 1911 (radium being used for medical purposes). From the 1930s, Radium Hill was operated as an underground mine.According to Thyer (1979), following the conclusion of the Aerial Geological and Geophysical Survey of Northern Australia (AGGSNA) in 1941, the then remaining geophysical staff were transferred to what became known as The Mineral Resources Survey (MRS) led by H G Raggatt, the Geological Advisor to the Commonwealth. Several surveys were carried out by the MRS (see Thyer, 1979) from 1941 until 1946, when the federal government created the Bureau of Mineral Resources, Geology and Geophysics. In 1944, the British and Australian Governments requested that a search for uranium deposits commence, and officers from the MRS carried out surveys in the Mount Painter and Radium Hill areas of South Australia, the only areas where uranium had previously been mined (Dickinson, 1954).The surveys at Mount Painter were conducted by R F Thyer in August-September, 1944 using a Geiger-Mueller ratemeter built in the Physics Department of Adelaide University. Surveys at Radium Hill were conducted by J M Rayner and C H Zelman using a G-M ratemeter and counter mounted on a truck (the first mobile survey). Surveys continued at both areas through 1945 (Thyer, 1979).In 1948 tax concessions were offered by the Commonwealth for successful discoveries, which encouraged individual prospectors to participate.In 1950, the geophysical branch of the South Australian Dept. of Mines conducted radiometric logging of diamond drill cores and a scintillometer survey of the underground workings at Radium Hill.During the early establishment of the BMR, newly built scintillometers from Canada and the United States were included with airborne magnetometer surveys from 1952 on, with the first being at Rum Jungle in the Northern Territory in August, 1952 and Radium Hill in November, 1952.While radiometric surveys can detect uranium directly, other geophysical methods also have important applications to uranium exploration situations. Gravity, magnetic, electromagnetic, and induced-polarisation surveys, conducted on regional and local scales, can be shown to be useful over a wide variety of uranium deposits.ReferencesDickinson, S.B., 1954.
