  • Western Australia is the only State from which vermiculite is produced. Occurrences are known in some of the other states and in the Northern Territory, but the information is not sufficiently detailed to enable their importance to be assessed. Vermiculite occurrence by State and Territory, and processing capabilities, are detailed in this report.

  • Salt is harvested from the surface of Lake Cowan, approximately 8 miles east of Widgiemooltha. This report follows a visit to the lake in July, 1945, and comprises notes on geology, salt deposits, grade, and harvesting.

  • The work described in this report forms part of the uranium investigation being conducted by the Commonwealth Government for the British Government. The work was carried out at Mt. Painter from 7th February to 26th March, 1945, following prior geophysical work. This report covers work including setting up and calibrating the assay equipment, and testing 100 samples from the Mount Painter No. 6 workings and 12 samples from East Painter No. 1 adit. In addition, some field work was carried out on Radium Ridge using a new type of portable equipment. The report is divided into two parts, the first dealing with the assay work and the second with the field work.

  • Results of a micropalaeontological examination of samples from bores Nos. 3855 and 3859. Samples were from the depths of 7 to 427 feet down and 1 to 977 feet down respectively.

  • Results from the micro-examination of samples from 2254 to 4554 feet down, No.2 Bore, Boronga. The series examined is in continuation of that reported upon 30th May, 1942.

  • The first discovery of bauxite in South Gippsland which was brought to public notice is said to .have been made in 1918 by Mr. Donald Clarke on the property known as Nahoo , allotment 8, Parish of Narracan South. Bauxite from this deposit has been used for chemical purposes for over twenty years. It is understood that other occurrences had been noted prior to Mr Clarke's report. Eleven additional discoveries were made from time to time up to April, 1942, when the extensive prospecting programme mentioned in the foreword was undertaken. In the short time that has elapsed since then a further twelve deposits have .been discovered, making a total of 24 deposits in the adjoining parishes of Moe, Allambee East, Narracan South, Mirboo and Budgeree in the county of Buln Buln. Several of these deposits have been systematically tested by shaft sinking and boring. The deposits at Boolarra, Oallignee and Nahoo have been reported on very briefly by Whitelaw (1921), Ferguson (1936) and Baragwanath (1940), but there have been no detailed descriptions of the deposits and no general account of their geological relationships. It should be noted that there has been no authenticated report of the occurrence of bauxite in Victoria outside South Gippsland and that little is known of the deposits other than those in the Boolarra-Mirboo North area.

  • Report on mine maintenance, costs, equipment, employment, reserves, and workings.

  • This report describes the field evidence in support of supergene origin for the torbernite deposits in the Mount Painter district. This origin is also emphasised by Stillwell and Edwards. This report was originally written in response to a preliminary report by Stillwell in which a hydrothermal genesis was favoured.

  • Bore No. 3853 on E.W. Langbien's Bullaroon Station, Bourke is situated 2 miles west-northwest from Bore No. 3825 on the same property and reported upon 7/12/43 and 2/11/44. This report details the results of the micro-examination of samples taken from 28 to 386 feet down.

  • The mine manager at Mount Bischoff Tin Mine, Mr. Eddy, proposes to mine the Greisen Orebody by means of a system of gloryholes, in combination with stoping. It was requested that a scheme of development work necessary for opening up the orebodies preparatory to mining should be decided on and set out on paper. This report is concerned with the proposals for development and testing work which would determine whether the larger gloryhole would be justified or whether a smaller gloryhole on the hanging wall ore and stoping on footwall ore would be a more profitable method.
