The dykes which contain the felspar outcrop lie on the western slope of a hill two miles east of Wodonga, and south-southeast from Albury. This report comprises notes on the occurrence of the felspar and descriptions of the individual deposits.
-
The barite deposits are about three miles northeast of Bredbo, which is nearly 50 miles south of Canberra. This report provides a description of the deposits.

The mine was examined on Monday, June 21st, and the surface and underground workings were mapped by tape, compass and clinometer. An account of the examination and its findings is given in this report. The general geology of the district, economic geology, and calculated ores reserves are described.

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).
