  • 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.

  • The writer spent four days in 1949 in the Adaminaby-Kiandra Area with J. Glover mapping the country north-north-east of the present Tunnel Line. In 1951 a fortnight more was spent on the Tunnel Lines themselves by the writer under the guidance of senior geologist D.C. Moye and geologists K. Sharp and C. Wood, who provided a large amount of information not yet available in written form. All sediments in the Tunnel Area are Ordovician, and in the case of the Tumut Pond beds an even older age is possible.

  • Attention has been directed to the cobalt workings at Carcoar as a possible source of radioactive minerals in two ways. During testing of museum specimens for radioactivity, it was found that cobalt ore from Carcoar was strongly radioactive. Also, the occurrence of uranium in the cobalt ores was reported by Mr. McKillop, formerly a land holder in the area, who submitted a copy of a report signed by Professor T.H. Laby, certifying the presence of uranium in samples examined by him, and at a later date, a sample containing an uranium mineral. A brief visit was paid to the area in 1948, and the presence of strong radioactivity on dumps was confirmed. A more extensive survey of the area was, therefore, undertaken by geophysicists during 1949-50 and 1950-51. This report gives an account of the geophysical operations carried out in the vicinity of the Carcoar cobalt workings and describes the results of these investigations.

  • 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.
