Inspections were made of the Burra, Kapunda, Wallaroo, Moonta, Hamley, and Kanmantoo Copper Mines, and a number of smaller mines on the outskirts of the main mining centres. There follows a review of each of the areas in the order visited.

On Saturday, 20th September, we visited the Chemistry Department, Crawley, Western Australia, and saw the experimental plant erected for the treatment of Lake Campion alunite. The process was discussed with Professor Bayliss and Mr. H. Bowley, Government Mineralogist and Assayer. On the morning of Monday, 22nd September, we met the Minister for Mines, State Officials and Messrs. F.B. Norwood and L. Gibbons at the Mines Department, Perth. At this meeting the Whim Creek and Ravensthorpe (Phillips River) copper areas were discussed. On the afternoon of the 22nd we met the Aluminium Panel at the Department of Industry and discussed the Lake Campion proposals. On Tuesday 23rd, lateritic bauxites were examined as several localities on the Darling Range and at Toodyay. Following is a review of the matters discussed in Western Australia.

Geological investigation by the Bureau commenced late in July, 1948, and continued until the end of October of that year. The objects of the survey were to lay the foundation for future detailed studies of the mining field, to study the factors controlling ore localization, to assess the quantity and value of ore exposed to date, and to estimate the potential value of the field. In the search for orebodies, a knowledge of the geological factors can be of great assistance, and it is felt that the information given in this report and in the accompanying plans should be of considerable help in this respect. However, the prospector's methods - loaming, dollying, panning etc. are still quite fundamental to success in a prospecting field such as Tennant Creek and the suggestions made in this report are intended to supplement this type of work. The climate, topography, vegetation, gold production, general geology, and gold deposits of the area are described in this report. Detailed descriptions are given of the individual mines examined to date.

Prospectors J.C. Paul and T.C. Ash claimed to have discovered wolfram near Lake Koolymilka in the area reserved for the Long Range Weapons project. The general geology and working of the area are briefly outlined in this report, and it is shown that no wolfram or any other minerals of economic importance are present.

The scientific search for ore in Australia is still in an early stage of development, because, until recently, a sufficient supply of metals was available from concentrations readily detectable by ordinary prospecting methods. Now the whole mineral supply position is changing and the rate of discovery of new deposits by prospectors in the present century had been quite discouraging. The Australian Government and the Australian mineral industry have recognised the need for mineral exploration both to supply home requirements and to assist in overcoming world shortages. An overview of the situation is presented in this report, which outlines the problem and the corrective reforms and activities undertaken by the state and federal governments, and mining companies, to promote mineral exploration. A summary is given of the exploration and ore-finding work undertaken by mining companies and government agencies between 1930 and 1949.

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 Treasure Mine, Hatches Creek, is believed to have been discovered in 1914 and has been one of the most consistent producers of wolfram to the present time. This report gives an account of the economic geology of the mine. The ore type, reefs and workings, ore localization, and ore reserves are described.

The Mosquito Creek Wolfram Field was visited on 6th and 7th October, 1951. This report gives a brief account of the inspection. The general geology of the area, the ore-bearing reefs, and the mining leases inspected, are described.

This mine, which is also known as the Magword Antimony Mine, is situated about 30 miles easterly from Guyra. The geology and workings of the mine are discussed in this report.
