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.

Summary report on the ore prospects of some Western Australian gold mines. The report provides details on production, ore deposits, and operations.

Brief description of limestone from a locality half a mile north of Cape Leeuwin Lighthouse.

The report describes the results of a micropalaeontological examination of samples taken from the depth of 30 to 100 feet.

This report covers the plane table survey work carried out from December, 1947, to February, 1948, on the ridge running N.W. from the U.S.A. Legation, and from Brick Trig. Station to the Brick Works. The stratigraphy, soil, structure, and topography of the area are discussed in the report.

The first geological reconnaissance of the proposed diversion of the Snowy River to the Murray Valley was undertaken in late 1946. This work was followed by more detailed work in the summer of 1947-8 when field parties carried out a reconnaissance of a strip of country covering the approximate route which the main tunnel is expected to follow. Part I of this report deals briefly with the geological work accomplished during the two field seasons and provides a summary of the engineering geology of the main and subsidiary tunnel lines. Parts II and III consist of the geological reports by the leaders of the two field parties. Part II covers the survey area from Waste Point to the Geehi River. Part III covers the survey area from the Geehi River to Khancoban. Accompanying plans are included.

This work was undertaken to extend regional mapping in the central and western portions of the A.C.T. and to provide a geological map of the Cotter River Area for use in engineering investigations. The regional geology portion of the Cotter Valley between Gingera and Bull's Head had previously been mapped on a scale of 1/2 mile to the inch, and this map was extended, by the recent survey, northwards to the Territory border and north-easterly to the Murrumbidgee River.

This report describes the results of the micropalaeontological examination of five rock samples collected from the south side of the Desert Basin.

It has been fairly firmly established that the fineness of the gold in any ore deposit varies with the depth from the surface at which the deposit was formed and as a corollary to this, that it is dependent upon the temperature and pressure at the time of deposition. This relationship is such that, under certain conditions, the gold fineness, taken into consideration with other recognised criteria, furnishes a very sensitive and reliable guide to the relative temperature of ore formation, at least within the epithermal and the upper part of the mesothermal range. The definition, determination, relation to deposits, and application of gold fineness are discussed in this report.
