The Cobar field was visited during the period 18th to 24th July, mainly in connection with the exploration programme which is taking place in that area. During this visit, however, some information was obtained concerning the operations of the mines controlled by New Occidental Gold Mines, N.L., which company is being assisted financially by the Commonwealth. Estimated operational costs, grade, and production figures are given. The development, exploration, and future of the field are discussed.

Attention was directed to the inadequacy of supplies of acid grade fluorspar in Australia when the Bureau of Mineral Resources was asked to sponsor an application to import a quantity from England in 1948. The British Ministry of Supply released a proportion of the amount required but advised that the supply position in England was not secure and only limited quantities could be released for export in the future. The Ministry suggested that if known Australian requirements were likely to be heavy, some material might be supplied as a matter of urgency. An investigation of the fluorspar industry in Australia was then undertaken to estimate future requirements and the extent to which these could be met from domestic sources; the results of this investigation are the subject of this report. The uses, grading, consumption, supply, prices, and projected future supplies of fluorspar are discussed.

Shortly after I took up the appointment of Mineral Economist, the high quality of the mica from the Harts Range came to my notice. Accordingly, I paid a visit to Harts Range between the 22nd September and 4th October. In judging the possibilities of developing the mica deposits of the Harts Range, the difficulty is the almost complete lack of reliable detailed mining data in the past - production data for the later war years only are available. However, by comparing the degree of areal concentration of the pegmatites, the type of deposits and the quality and sizes of the mica so far produced with those in India, a reasonable picture can be obtained of comparative possibilities. The method of approach throughout this report, therefore, will be comparison of the Harts Range with India mica. This report gives an account of the present state of the Australian mica industry, including descriptions of current trade terms, the grading and classification of mica, and the Harts Range Mica Belt deposits. Suggestions and recommendations for the development of the industry are discussed.
