  • A geological examination of the Renison Bell Tin Field was made in company with Mr. H.G.W. Keid, Field Geologist, Tasmanian department of Mines, during January and February, 1942. Workings, lode outcrops and the principal topographical features were mapped by plane table on a scale of 100 feet to an inch, and all accessible underground workings were plotted on a scale of 40 feet to an inch. Surface exposures were poor, owing to dense growth of bracken and other scrub and were largely confined to the vicinity of present or previous workings, tramlines, tracks, roads and railway lines. The history and production, geology, and economic geology of the field are outlined. The individual lodes are described in some detail. Methods of mineral exploration are discussed.

  • This progress report follows a general report on the Wymah field by N.H. Fisher and C.L. Knight, submitted in June, 1942. It contains details concerning the development, ore structures, and mineral reserves of the Wymah wolfram mine.

  • The samples of diatomite were received recently from the Director of the Geological Survey of New Zealand. The localities for the samples are given as Middlemarch, Wainui and Whirinaki. The three diatomites are of freshwater origin. The following notes are the result of microscopic examination.

  • A brief description of the talc deposits is given in this report. Details including situation, geology, and tonnage are noted.

  • This report is written as a result of observations made at Mansfield during an examination of the phosphate deposits in company with members of the Joint Parliamentary Committee on Rural Industries on the 20th March.

  • This report gives a brief overview of the situation and geological features of the barite deposit.

  • The occurrence of molybdenite deposits near Yetholme has been known for many years. The most important deposits are close to the eastern boundary of Ph. Yetholme, Co. Roxburgh. The deposits have been worked in a small way for molybdenite at several places, have been examined by several geologists, and have been investigated by two of the major mining companies. The result of this work has shown that although considerable tonnages are available, the molybdenite content is too low to make mining attractive. It is not proposed to describe the geology, mining excavations, and other factors affecting the field in this report since that has already been done in several previous reports. It is the purpose of this report, however, to point out that the Yetholme deposits contain a considerable amount of scheelite and may well warrant large scale mining for this now important ore of tungsten.

  • Ajana is 66 miles north from Geraldton by rail and is the terminus of the branch railway which passes through Northampton mining district. Aspects of regional geology and mineral occurrence are discussed in these notes.

  • The Womobi wolfram mine is situated in M.I.6798 in the Parish of Thologolong, County of Benambra, one mile east of the main Murray Valley Highway and 42 miles by road easterly from Albury. The mine was mapped on September 4th, 1943. The surface was mapped by plane table on Decemeber 1st, 1943, in company with Mr B.P. Utting, and underground mapping brought up to date. The mine is developed by a short adit to the reef, with drives along the reef system 370 feet east and 240 feet west, the west drive being connected to the surface by another adit opening. A connection has been made to the surface from the east drive at 190 feet from the adit, and two short rises were previously in existence 20 feet or so on either side of the adit. At 30 feet in the west drive a winze was sunk 50 feet and a level has been driven along the lode. Stoping is in progress above this level and above the east level.
