  • The Australian Geological Provinces Database contains descriptions and spatial extents of the fundamental geological elements of the Australian continent and offshore surrounds. Province types include sedimentary basins, tectonic provinces such as cratons and orogens, igneous provinces, and metallogenic provinces. Spatial data has been captured largely at approximately 1:1M scale for intended use between 1:2M and 1:5M scale.

  • Six scout drilling holes totalling 1020 feet of drilling were sunk by the Bureau in the Stony Pinch and Thornton Area, about 6 miles south-south-east of the City of Maitland in the Hunter Valley of N.S.W. The bores penetrated the Four Mile Creek beds and the Buttai Sandstone of the Tomago "Stage" of the "Upper" Coal Measures. In the absence of reliable stratigraphical control, the seams cannot be correlated with much certainty. Bore BMR 4 Stony Punch indicated that Donaldson's Seam(?) is thin and much banded; the coal, excluding bands, has an ash content of about 15% and calorific value of 12,300 B.Th.U/lb. This same bore showed that the basal 7 feet 3 inches of the Big Ben Seam had an ash content of about 25% and calorific value of 10,600 B.Th.U/lb. if 8 inches of non-coal bands are excluded. The general results of the drilling were that the coal seams were heavily banded, variable and high in inherent ash. Accordingly the prospecting was halted after drilling six holes.

  • Howards Springs are situated about 3.5 miles north-east of a point on the Stuart highway about 16 miles south of Darwin. They are seepage springs on a branch of the Howard River. Radioactive material was found in the area by Mr. L. Good, Box 273, Darwin, during October, and samples were sent to Rum Jungle for testing. A brief inspection of the area was made by the writer and Dr. N.H. Fisher on 7th November, 1952. It seems likely that the mineral causing radioactivity has been precipitated, probably by organic matter, from the spring water in the black clay layer, but the original source of the material is not at present clear.

  • A map showing selected mines, mineral deposits and historice mines on the radiometric map of Australia. 1:5 million scale.

  • Australia's Identified Mineral Resources 2010 presents estimates of Australia's mineral resources at end of December 2009 for all major and several minor mineral commodities (Table 1) based on published and unpublished data available to Geoscience Australia. These resource estimates provide a long term view of what is likely to be mined. They are compared with national totals of ore reserves for each commodity, which provides the industry view of what is likely to be mined in the short to medium term. Mine production data are based on figures from the Australian Bureau of Agricultural and Resource Economics and Sciences. World ranking of Australia's mineral resources have been calculated mainly from information in publications of the United States Geological Survey. A summary of significant industry developments also is presented. Australia's Identified Mineral Resources 2010 provides information on and analysis of mineral exploration expenditures in Australia for 2008-09 and the calendar year 2009. Trends in expenditure are presented and discussed.

  • The Cobar field was visited during the period 18th to 24th July, mainly in connection with the exploration programme which is taking place in that area. During this visit, however, some information was obtained concerning the operations of the mines controlled by New Occidental Gold Mines, N.L., which company is being assisted financially by the Commonwealth. Estimated operational costs, grade, and production figures are given. The development, exploration, and future of the field are discussed.

  • Four deposits at Ellsmore were sampled for bauxite content. The results, showing the economic bauxite proved, are tabulated in this report. Figures are given for each of the individual deposits and for the Ellsmore area.

  • At least as early as 1940, it was realised by the Department of the Interior that the reserves of suitable rock (shale or slate) in the pit adjacent to the Canberra Brickworks were limited. A decision was made to find a temporary site to provide sufficient material to supply the brickworks for two years. A site at Deakin, 1700 yards by road east from the existing brickworks was selected and was recommended by Dr. W.G. Woolnough in 1940 as suitable, subject to testing by costeans and pits. A survey of the area in the subdivision of Deakin, Canberra City Area, was then arranged and was made during March and April, 1944, the object being to determine if there were sufficient reserves of suitable material to supply the Canberra brickworks for a period of not less than two years. This report describes the results of this survey.

  • Red ochre of high quality has been produced from deposits in Ophthalmia Range since 1937. The bulk of the production has been derived from one lease, No. 37OH, the deposits on which are the subject of this report. The locality was visited in June, 1944. This reports comprises notes on access, topography, geology, economic geology, and production. A geological plan of the vicinty of the ochre deposits accompanies this report.

  • Brief descriptions and estimates of the size and grade of the more important known uranium deposits in various parts of the world.
