This report is written chiefly to present estimates of reserves of bauxite proved to date in Gippsland. Consequently, discussions of the geological aspects of the investigation, though essential to an understanding of the subject, are kept to a minimum. The existence of bauxite in the neighbourhood of Boolarra and Thorpdale, County Buln Buln, South Gippsland has been known for some years and bauxite from Nahoo, Allot. 8 Ph. Narracan South, has been used for chemical purposes for over 20 years. Eleven additional discoveries were made from time to time up to April, 1942, when an extensive prospecting programme was undertaken. In the short time that has elapsed since then a further twelve deposits have been discovered, making a total of twenty-four deposits in the adjoining parishes of Moe, Allambee East, Narracan South, Mirboo and Budgeree in the county of Buln Buln. Several of these deposits have been systematically tested by shaft sinking and boring. This exploration is still in progress.
