The Lakes Entrance Oil Shaft is situated in allotment 21, Parish of Colquhoun, about 2 miles north-east of Lakes Entrance township. The shaft was sunk with the object of developing, by means of low pressure mining methods, the oil-bearing beds known to exist in the lower portion of the Tertiary basin in the Lakes Entrance area. It is estimated that, during mining operations, approximately 12,000 tons of Tertiary sediments were excavated. Consequently a unique opportunity was afforded the palaeontologist and geologist to study the stratigraphic sequence of Tertiary beds in the Lakes Entrance area. During visits paid to the scene of operations, extensive collections of fossiliferous material were made by the author. This report comprises notes on the scope of the micro-palaeontological investigation, the stratigraphy and the palaeontology of the Lakes Entrance Oil Shaft.

An examination was made of a proposed dam site at Geehi in April, 1947. The report comprises notes on access, general geology, evidence gathered from aerial photography, and the suitability of the site. Three accompanying plans, and a petrographic report on rocks collected from the vicinity, are appended to this report.

Collie is the only developed coalfield in Western Australia. Between June 1946 and April 1947 a comprehensive geological and geophysical survey was carried out to determine the boundary of the basin, its general configuration and the depth (thickness) of the sediments overlying the basement. The aim of the survey was to define those areas where there was sufficient thickness of sediments to enable drilling to be carried out with a reasonable expectation of proving additional reserves of coal. The geology of the area, application of the gravity method, results and interpretations, and drilling recommendations are discussed in this report.

Overview of general work, sampling, mapping and levelling, drafting, and laboratory work carried out during the month of September, 1947.

The geology, production history, ore grade, and ore reserves of the Northern Star Mine are discussed in this report. Four accompanying plans are included.

Report on surveying, sampling, and plant sampling work carried out during the month of July, 1947.

This geophysical survey was undertaken as part of a campaign by the N.S.W. Mines Department and the Commonwealth Bureau of Mineral Resources to explore the ore possibilities of the Cobar Mining Field. Tests, made in January 1947, on specimens of ore from the operating mines showed that some of the ore from the New Cobar and Chesney Mines exhibited appreciable magnetisation due to its pyrrhotite and possibly magnetite content. The survey was commenced in March, 1947 using the magnetic method only as a first method of attack. Watts Vertical Force Variometers Nos. 15887 and 16128 were used, the field work being carried out by the writers. The geology of the area, object of the survey, results, and recommendations for future drilling are discussed in this report. Two accompanying plans are included.

The aim of this examination was to map in as much detail as possible the structure of the Apinaipi Anticline, which is situated on the coast of Papua, 100 miles north-west of Port Moresby. The survey programme and the geomorphology, structure, and lithology of the area are discussed in this report. Accompanying maps and section plans are included.
