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

  • This summarised account of oil-drilling activities in Australia and New Guinea is given in two parts, first, a summary of past operations, and second, the status of investigations. Part 1 is almost entirely factual. The object has been to present a summary account of actual drilling operations, the results being obtained and the expenditure incurred therein. Part 2 states briefly the position we appear to have reached in the search for oil and summarises any present activity. The notes are given by States and Territories commencing with New Guinea and thence in clockwise order. "New Guinea" means the island of New Guinea and includes the Mandated section of the island as well as Papua.

  • Australia's Identified Mineral Resources is an annual nation-wide assessment of Australia's ore reserves and mineral resources.

  • In Portion 11, Ph. of Stockrington Diamond Drilling near an unnamed creek tributary to Surveyor Creek has disclosed coal continuously for a distance of 7,600 feet south from the northern boundary of the Portion. The seam is split and banded and the coal is inherently high in ash. Proximate analyses of the coal were carried out by the New South Wales Mines Department laboratory in Sydney. All coal ores were forwarded from the field and shale etc. bands of greater thickness than half an inch were discarded by the analysts. Stony coal or carbonaceous shale with S.G. greater than 1.6 was also rejected from the assay samples. Consequently the analyses quoted indicate a composition roughly equivalent to that which might be expected for cleaned or hand-picked coal from this area.

  • This statement sets out the results of drilling in part of the Minmi Area, Newcastle District. The area covered by the drilling grid totals about 390 acres and includes parts of Portion 130, Ph. of Teralba and Portions 15 and 26, Ph. of Hexam. This statement refers to the western and central blocks of the area. Proximate analyses and calorific value determinations of the coal cores were made by the New South Wales Mines Department laboratory in Sydney. The analyses here quoted indicate a composition roughly equivalent to that which might be expected for cleaned or hand-picked coal from this area.

  • 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.

  • Geological investigation by the Bureau commenced late in July, 1948, and continued until the end of October of that year. The objects of the survey were to lay the foundation for future detailed studies of the mining field, to study the factors controlling ore localization, to assess the quantity and value of ore exposed to date, and to estimate the potential value of the field. In the search for orebodies, a knowledge of the geological factors can be of great assistance, and it is felt that the information given in this report and in the accompanying plans should be of considerable help in this respect. However, the prospector's methods - loaming, dollying, panning etc. are still quite fundamental to success in a prospecting field such as Tennant Creek and the suggestions made in this report are intended to supplement this type of work. The climate, topography, vegetation, gold production, general geology, and gold deposits of the area are described in this report. Detailed descriptions are given of the individual mines examined to date.

  • 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.

  • This statement, supplemented by graphic bore logs, sets out the results of a drilling campaign conducted at Cocked Hat Creek immediately west of the village of Young Wallsend, Newcastle district, by the Bureau in accordance with an agreement between the Mines Department of New South Wales, the Joint Coal Board and the Bureau. The area covered by the drilling grids totals about 200 acres, and includes parts of Portions 55, 69, 73 and 79, Parish of Teralba, County of Northumberland. It is known that this area, and a large extension to the north amounting to at least 4 square miles, is underlain by the Australasian seam which had been intersected at 50 feet from the surface in Portion 60 where it is approximately coincident with sea-level. Also the seam is exposed at various points along the northern margin to the larger area at elevations ranging from 170 to 220 feet. The purpose of the drilling was to test the thickness and quality of this seam, hitherto almost unknown factors, and to determine whether a potential open-cut site worthy of more exhaustive investigation exists.
