The operational history, orebody, workings, grade, tonnage, and financial considerations relating to the Chesney mine are discussed in this report. Two geological plans are included.

An overview of the occurrence and testing of bauxite deposits in Australia.

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.

In response to the proposal for a new administrative building to be erected, 1/4 mile east of Parliament House, nine test pits were put down by the Department of the Interior for the purpose of examining the sub-surface conditions. Four of the pits were used for engineering tests of the bearing power of the rock foundations. The geology of the site is discussed in this report.

The geophysical test survey of this field was commenced on 5/6/45 and operations were terminated on 6/8/46 when it was considered advisable to await the results of the drilling campaign for guidance in planning the future geophysical programme. The most intense work was done on the south-east gossan area where the methods used included, electromagnetic, potential-ratio, spontaneous polarisation, magnetic and resistivity. This interim report is supplementary to a detailed report of the survey and refers in detail only to some of the results on the south-east gossan area.

This report deals with all the known bauxite deposits at Ouse including one occurrence on Cleveland Estate. This report comprises notes on the general situation, access, geology, and bauxite reserves at Ouse, along with descriptions of the individual deposits.

Progress report on the testing campaign, commenced in May, 1945, of the bauxite deposits at Ouse, Tasmania, No. 2 Area.

Two earlier reports on this subject dealt with this industry on the basis of information then available and virtually omitted from consideration the activities of the producer and consumer subsidiaries of the Colonial Sugar Refining Company. This company has now supplied detailed information, particularly on its plans for production and it is therefore necessary to review the industry afresh. The production and consumption of asbestos in Australia are discussed in this report.

The extent, structure, and thickness of the Coorabin coal measures are discussed in this report.

Brief descriptions and estimates of the size and grade of the more important known uranium deposits in various parts of the world.
