A report on the results of a micropalaeontological examination of samples taken from the depth of 2,000 feet down to 3,132 feet. This series is in continuation of that reported upon on 19/3/46.

On June 20th King Island Scheelite N.L. asked for advice on the location of suitable drill holes north of their present 150 and 170ft. faces to determine the geology along the No. 3 fault. In this report a scheme of drilling is set out, which would determine the geological structure of the area and indicate tonnage of ore and overburden. A plan is attached to the report which shows the bench limits, the main geological features and selected diamond drill hole sites.

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.

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.

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.

In response to a request from Mr. W.H. Williams, Director of Mines, Tasmania, a geological survey was made of the asbestos deposits situated near the tunnel on the Emu Bay railway, 5 miles north-east of Zeehan. A programme of investigation was set out involving a detailed survey of the deposit, prospecting and development work, an assessment of potential fibre grades and ore values, and research into milling practice and market utilization of fibre. The geological survey and related investigation, which are the focus of this report, were concerned mainly with the first three items. Three plates, including a geological map, surface plan, and a plan showing underground workings and effective grades, are attached to this report.

The Pioneer tungsten-bismuth mine, Hatches Creek, was discovered in 1917 and worked on a small scale from then until a short time after the conclusion of World War I, when production ceased owing to a fall in tungsten prices. Prices rose again in 1937, and exploration resumed. The general geology, ore bodies, and working of the Pioneer mine are discussed in this report.

A visit was paid to Gidleigh Station on Saturday, January 12th. The ten bores previously put down on the property were examined. Details including depth, flow, elevation, and the results of observations made at the site, are given in this report.

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