A preliminary geological examination of an area at the northern extremity of Gungahlin district was carried out for the purpose of determining with fair approximation the area occupied by slate apparently suitable for brick-making. The geology of the area and the suitability of the site for a brick pit are discussed in this report. A geological sketch map of the district is included.

Greenwood's Camp area is situated approximately 1/2 mile east-northeast of the East Painter Camp at the junction of Heighty Creek and an un-named creek along which runs the camel pad to the Mount Painter divide. A reconnaissance survey of the area was made during which a number of small torbernite occurrences were discovered. The area was later mapped in more detail by E. Broadhurst and K. Llewellyn and during the course of their examination the No. 5 prospect was discovered. As a result of his examination Broadhurst recommended that a Geiger-Muller radiation survey should be made of those parts of the area which he considered most likely to contain torbernite or other uranium minerals. The survey under review was carried out as a result of this recommendation. The geology of the area, technical matters, and the results of the survey are discussed in this report.

The pressure of the liquid, or reservoir pressure, within the glauconitic sandstone at Lakes Entrance has been the subject of conjecture in recent years and the low yields of oil which typify the field have been attributed by some observers to low reservoir pressure. Reservoir pressure, however, is only one of a number of factors upon which the rate of yield depends. Other factors of equal importance are the permeability of the producing formations and viscosity of the fluids produced. The methods, tests, and results involved with the determination of reservoir pressure from liquid level data are discussed in this report.

Bore No. 3831 on W.L. Fennell's property is situated about 30 miles northeast of Langbien's bores. This report describes the results of a micro-examination of samples taken from 6 feet down to 1118 feet.

Findings from a micro-examination of samples taken from the depths of 2,110 feet down to 3,533 feet 11 inches. The series is in continuation of that reported upon 11/10/44.

The bore under discussion is the first of a series which is being examined for a microfauna from the Great Artesian Basin in South Australia. The samples examined were collected from the surface to the depth of 380 feet. A description of the bore and detailed report of the microscopic examination of the bore samples are given in this report.

Report on mine maintenance, costs, equipment, employment, reserves, and workings.

Results from the micro-examination of samples from 2254 to 4554 feet down, No.2 Bore, Boronga. The series examined is in continuation of that reported upon 30th May, 1942.

On 21st November, 1944, a visit was made to the above block at the request of the lessee (Mr. G.D.C. Tanner) who had asked for advice regarding water supply. The report following this visit recommended the testing of an alluvium-filled basin which occupies part of the southeastern quarter of the block. Subsequently Mr. Tanner sank a well at a site about 1,000 feet south of the point indicated as most favourable. For all practical purposes it may be considered that the well has proved that the alluvium is not capable of yielding a useful supply of water at the end of a dry period, and it became necessary to consider the possibility of obtaining water from the bedrock. The present report embodies results of a further examination with this end in view. The location, topography, geology, and possibility of underground water at Block 10 are discussed in this report. A geological sketch map of Block 10 is included.
