This report describes magnetic investigations made at East Arm, for the purpose of determining whether a certain area would be suitable as a site for an aircraft compass swinging base. A similar survey was made on an adjoining area in December, 1944 (Report No. 1945/1) where magnetic conditions were found to be satisfactory but for other reasons the general design was altered and the site of the proposed swinging base was moved from that area. On 9th June, 1945, a request for investigation of the new site was submitted. The instruments used and the methods employed were similar to those used in the December survey and the report on that survey should be consulted for details of the same. The results of the survey are discussed here. Two accompanying plans are included.

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.

Notes on beach sand workings by company at September 1st, 1945.

Report on six samples of limestone from localities in Flinders Island, Tasmania.

Ten samples from a bore were submitted for micropalaeontological examination. The first sample was taken at a depth of 19-35 feet and the last at 417-425 feet. As these samples are the first in a series from bores in the Mt. Burr area, the fossil content of each sample is listed in detail, so that it can form a basis for the work on samples from other bores. At the end of the report a complete list of fossils determined, together with their distribution in the samples, is given.

Results of a micropalaeontological examination of samples from the depth of 25 feet down to 563 feet.

The first discovery of bauxite in South Gippsland which was brought to public notice is said to .have been made in 1918 by Mr. Donald Clarke on the property known as Nahoo , allotment 8, Parish of Narracan South. Bauxite from this deposit has been used for chemical purposes for over twenty years. It is understood that other occurrences had been noted prior to Mr Clarke's report. Eleven additional discoveries were made from time to time up to April, 1942, when the extensive prospecting programme mentioned in the foreword was undertaken. In the short time that has elapsed since then a further twelve deposits have .been discovered, making a total of 24 deposits in the adjoining parishes of Moe, Allambee East, Narracan South, Mirboo and Budgeree in the county of Buln Buln. Several of these deposits have been systematically tested by shaft sinking and boring. The deposits at Boolarra, Oallignee and Nahoo have been reported on very briefly by Whitelaw (1921), Ferguson (1936) and Baragwanath (1940), but there have been no detailed descriptions of the deposits and no general account of their geological relationships. It should be noted that there has been no authenticated report of the occurrence of bauxite in Victoria outside South Gippsland and that little is known of the deposits other than those in the Boolarra-Mirboo North area.

This report describes the field evidence in support of supergene origin for the torbernite deposits in the Mount Painter district. This origin is also emphasised by Stillwell and Edwards. This report was originally written in response to a preliminary report by Stillwell in which a hydrothermal genesis was favoured.
