The Dundurrabin copper prospect is 3.5 miles northwest of Dundurrabin sawmill and settlement, and 5 miles from Lyringham, which is connected by road to Grafton, Armidale and Dorrigo. The mine is favourably situated with regard to supplies of water and timber. Development consists of an adit to the lode with a cross-cut through it (Plate I), connected to a shaft from the surface on the south wall of the lode. The shaft has been sunk 30 feet below the adit with another cross-cut at that level through the formation. A few pits and costeans have been put down along the strike. Geology, prospects, and recommendations for further work are discussed.

The period 30th to 31st May, 1946, was spent in selecting five sites for diamond drilling at the Cosmopolitan Howley Mine, Brocks Creek district. A description of the geology and the conclusions reached as regards drilling are given in this report. A plan of the mine and sections plan are included.

Five leases were taken up by the Commission in the Parishes of Jeeraland, Traralgon, Budgeree and Yinnar in the County of Buln Buln. These notes give brief descriptions of three of these leases and also contain some recommendations relative to prospecting on them. Two geological sketch maps are included.

The overburden (or non-scheelite bearing rocks overlying the ore-bearing rocks) at the mine of the King Scheelite N.L. at Grassy include: 1) A layer of windblown sand ranging in thickness up to 30 feet; 2) An irregular layer of non-mineralised rocks occurring in the north-western part of the present workings; 3) Non-mineralised rocks conformably overlying the lode in the southern part of the workings; 4) Overburden dumped on the southern side of the open cut. The problem of the dumping of the overburden is involved in that of the selection of a suitable site for the treatment plant. Under the proposed scheme to increase production a new site will have to be found for the treatment plant that is to be erected.

Mount Kitchin lies about thirty miles west from Chillagoe in Northern Queensland and is 13 miles by bush-track south-west from the now deserted town site of Arbouin on Cardross copper field. Six claims embrace the mica deposits at Mount Kitchin, but only three of these could be examined, on the 8th October, 1942, in the short time at disposal. The brief examination of these three claims, namely, "Wonder", "Anniversary" and "Southern Cross" confirms the remarks of Mr C.C. Morton in his report dated 1/5/42 to the Chief Geologist, Brisbane, and it appears that the "Southern Cross" and "Anniversary" claims contain the only deposits which may become producers in the future. When compared with the mica deposits of Central Australia the pegmatite bodies at Mount Kitchin are very small.

Australia's Identified Mineral Resources is an annual national assessment that takes a long-term view of Australian mineral resources likely to be available for mining. The assessment also includes evaluations of long-term trends in mineral resources, world rankings, summaries of significant exploration results and brief reviews of mining industry developments.

The enquiry into this mine resulted from an application by the company for a loan from the Commonwealth to carry out exploration and development. The Tindalls Gold Mine has not been examined by the Bureau and unless this is done no definite statement about the ore possibilities of the property can be made. However, from past reports it seems likely that the deposit has a chance of producing a large tonnage of ore. Under present conditions and with the mining methods now employed, it is extremely doubtful whether ore of this grade could be mined at a profit. The ore reserves, mining, milling, costs, and general financial outlook with respect to the mine are discussed in this report.
