In view of the shortage of tungsten supplies in allied countries, efforts are being made in Australia to increase production with a view to not only satisfying domestic requirements, but also exporting to Great Britain and the United States of America. The King Island scheelite mine is at present the largest producer of tungsten ore in Australia, and the possibilities of increased production from it were, therefore, among the first to be considered. Geological and geophysical surveys were made in June and July, 1942. A preliminary report was prepared in September and a drilling campaign drawn up to test the deposits with the object of proving sufficient ore-reserves to justify increased production for war purposes. Up till the present, fifteen drill holes have been completed and under a modified programme four remain to be drilled (two of these are in progress). This second preliminary report is based on the drilling and assaying results to date (details of thirteen holes are available).
