The period 17th June to 3rd July, 1953, was spent by the writer on the uranium fields. During this time an inspection was made of all work being carried out by the Bureau; in addition, the investigations by Territory Enterprise Limited at Rum Jungle were shown to the writer by W. Thomas, Resident Geologist.

Presentation to minerals industry representatives at the Geological Survey of Western Australia, 4 May 2010.

These maps were made initially for the PDAC 2001 International Convention. They have been published and made available via the web. There are two maps for each of the following commodities (gold, nickel, lead-zinc and copper). The first map depicts Australia's mineral occurrence locations, deposits, potential rock units and geological regions with the mineral occurrence density grid, while the second map provides an infrastructure theme and the mineral occurrence density grid. Infrastructure includes roads, railways and pipelines.

This is the second progress report of the coal drilling programme near Ashford in the Parishes of Macdonald and Myall, County of Arrawatta. The first report (Record 1949/106) covered the drilling of D.D.H's 1-5. Drilling was continued to test the coal measures lying between old Ashford Colliery and the Severn River. Five more holes were drilled through the coal seam, north of No. 2 D.D.H. An account of the drilling work is set down in this report, together with a description of local geology, and estimates of the coal reserves in the field.

Consequent upon instructions received from the Superintending Geologist, Mr. C.J. Sullivan, the copper-gold deposit at Yeuralba was visited and inspected on the 9th, 10th, and 11th May, 1950. This geological report gives an overview of the inspection and its findings. The situation, history, workings, general geology, orebody, mineralisation, and production history of the deposit are briefly described.

This report has been written as the result of conversations between the writers and officers of the Joint Coal Board in Sydney, Lithgow and Cessnock, and with similar assistance from the Geological Survey of New South Wales. The writers visited the Western and Northern coalfields during August and inspected most of the operating open-cuts. The results of the enquiries are presented in five tables which are set out at the end of this report and which contain, in statistical form, the greater part of all the information elicited. The text matter of the report is explanatory of the tables and also discusses the methods which have been used in arriving at the estimates of coal reserves. In the ensuing discussion emphasis has been laid on coal reserves available for open-cut mining, and all enquiries directed to the Join Coal Board were concerned with open-cut coal only.

Coal outcrops in the bed of a small gully tributary to the Severn River, at a point 7 miles north of the village of Ashford, 36 miles north of Inverell, New South Wales. A small colliery has been developed in the Ashford Seam and worked intermittently until 1925, mainly to supply coal and coke to the Silver Spur mine near Texas, Queensland. The coalfield and extensions to the north and south have been examined by officers of the New South Wales Department of Mines, the Australian Aluminium Production Commission, the Joint Coal Board and others. During March, 1949 a diamond drilling programme was initiated by the Bureau of Mineral Resources, Geology and Geophysics and both geological and geophysical investigation of the area was carried out by the Bureau during the early phases of the drilling campaign. The geology of the area, nature of the coal, and drilling results are discussed in this report. Logs of diamond drill holes and percussion bores sunk by a former lease-holder are given in the appendix.

In November, 1947, at the joint request of the Queensland Government and four companies which are associated with the search for oil in the area, the Bureau commenced geophysical work in the Roma district of Central Queensland. During the first phase of the geophysical operations, gravity and magnetic methods were applied in the reconnaissance of a large area. The object of these operations was to disclose gravity or magnetic anomalies which might be related to geological structures, indicate the broader structural elements of the sedimentary basin in which the oil and gas occur, and enable areas to be selected for investigation by more exact methods. The purpose of this report is to state clearly the geological problem and the geophysical methods adopted in the attempt to solve it. The geology of the area, possible oil-bearing structures, and the application of geophysical methods to date, are discussed. A sketch map and geological section plan are included.

In 1943, an investigation was carried out on portions of the Latrobe Valley Brown Coalfield, using the electrical resistivity method, to see whether or not this method could prove useful in determining the depth to coal. At this time, the possibility of a gravity survey was discussed, and in January, 1948, gravity tests were commenced using a Humble-Truman gravimeter. Later, a substantial number of the readings were repeated with a more modern type of gravity meter, and a few new stations established. The results were subjected to a preliminary investigation soon after the completion of field work, but it was evident that a much more detailed study would be required before an interpretation could be completed. Prior to these tests, discussions took place between technical officers with a view to selecting an area for testing on which the results could be related to some of the known geological structures, and, subsequently, an area was selected in the Parish of Hazelwood for this purpose. The geology of the area, survey method, and results are discussed in this report. Accompanying geological plans are included.

Black coal of Permian age has been found near Oaklands and Coorabin in the Riverina District, New South Wales. The coal is low-grade compared with the bituminous coals of Permian age at Newcastle, but has significance due to its situation in the south-western part of New South Wales, near the Murrumbidgee and Murray irrigation areas, and not far from the Victorian border. This report has been compiled mainly from field observations and from the files of the Bureau. The report gives a broad overview of the situation of the field and aspects of geology. The discovery, development, and workings of the coalfield are described. The characteristics of the coalfield are discussed, including petrography, the quality of the coal, the presence of water, and the extent of the field. Extensive data on the shafts and bores are appended. Accompanying geological plans are included.
