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. {"type": "Polygon", "coordinates": [[[134.5, -23.5], [135.5, -23.5], [135.5, -22.5], [134.5, -22.5], [134.5, -23.5]]]} 134.5 135.5 -23.5 -22.5 AU-NT GA Publication Geology Published_External Record geology industry mineral deposits mineral exploration resource assessment Download the Record (pdf) documentDigital Download the Record (pdf) PDF Unnamed resource documentDigital HTML
