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.

The second drill hole on the area of the Dapville No. 1 anomaly has been completed and some details of the results are given in this report. Following the discovery of this and other magnetic anomalies of low intensity in the course of surveying, there is a need for the determination of priority on the part of the operating company, in the testing of these anomalies. The principal purpose of this report is to draw further attention to the Peak magnetic anomaly and to discuss various factors which the company may desire to take into consideration in the determination of the priority question mentioned above.

This report describes the results of the micropalaeontological examination of five rock specimens from the Kimberley Basin.

This report describes the results of a micropalaeontological examination of thirty-one rock samples collected from the Andamooka and Coober Pedy opal fields.

This record describes the results of a micropalaeontological examination of samples collected from the depth of 30 to 1445 feet down.

The area was bored and sampled in May, 1948. Bores were put down to water level, using a post-hole digger. When the sand brought up from the boreholes appeared to contain appreciable quantities of heavy minerals, it was sampled by quartering. Sample weights, volumes, and dry concentrates were determined. Percentage composition of concentrates was determined by grain counting. The estimates of the quantities and grades of heavy mineral concentrates, the quantities of overburden, and the quantities of each of the heavy minerals are tabulated in this report. Data collected in the course of the investigation has been tabulated and is appended. Accompanying locality and section plans have been included.

This report describes the results of a micropalaeontological examination of two rock samples from the Kimberley district.

This report describes the results of a micropalaeontological examination of eight rock samples from Mount Canaway.

Samples from 37 bores were submitted by the Director of Mines, Adelaide, for micropalaeontological examination. Two of these bores were put down in the plains to the north of Adelaide and the remainder in the area to the south of the city. A short account of the stratigraphic sequence and detailed descriptions of the bore samples are given in this report.
