Following the recommendations of an earlier investigation, a visit was arranged in June, 1947, to inspect the deposits near Hampton, at Toowoomba, and in the South Burnett District. As a result of this inspection it was decided to start a testing campaign on Portion 194v, Wooroolin and to follow this work by testing in the vicinity of Portion 206v. The method to be employed and scope of any further work was to be modified in the light of experience gained at the first two areas, called Kingaroy No. 1 and Kingaroy No. 2 respectively. The geology of the area, methods of testing, and the nature of the laterite are described in this report. A comparison of the results of searches by the Queensland Geological Survey and by the Australian Aluminium Production Company is given. Accompanying plans are included.
