The mine was examined on Monday, June 21st, and the surface and underground workings were mapped by tape, compass and clinometer. An account of the examination and its findings is given in this report. The general geology of the district, economic geology, and calculated ores reserves are described.

An examination was made of a wolfram vein seven miles north of Broken Hill, on July 8th, 1943. This report contains brief notes on the nature of the vein and the mineral specimens examined.

A mineralight examination of scheelite occurrence at Hatches Creek and Wauchope was carried out. The results of the examination are recorded in this report.

This report describes the results of a micro-examination of rock samples from Mrs. F.F. Bennett's Bore No. 3805. The samples were taken between the depths of 17 feet and 1984 feet.

This summarised account of oil-drilling activities in Australia and New Guinea is given in two parts, first, a summary of past operations, and second, the status of investigations. Part 1 is almost entirely factual. The object has been to present a summary account of actual drilling operations, the results being obtained and the expenditure incurred therein. Part 2 states briefly the position we appear to have reached in the search for oil and summarises any present activity. The notes are given by States and Territories commencing with New Guinea and thence in clockwise order. "New Guinea" means the island of New Guinea and includes the Mandated section of the island as well as Papua.

Two samples of diatomite were recently received from Broken Hill Pty. Co. Limited for microscopic examination. They were from Nettle Creek, 9 miles north-east of Mt. Garnet and near Innot Hot Springs. The results of the microscopic examination are given in this report.

Report on a collection of fossils taken from three locations near the property of "Avondale", in the centre of King Island. This report comprises the list of fossils determined in the sample and notes on the fossil assemblage.

The Chilcot copper mine is situated 15 miles south-south-west from Orange, from which it may be reached by reasonably good road. It was examined during 1942 by Dr. N.H. Fisher, Chief Geologist, Mineral Resources Survey, who recommended that a geophysical survey be made to search for additional ore shoots along the lode channel (1942/020). The geophysical survey was made during the three weeks ending 19th December. Operations were commenced over the area north-east of the mine, extending a distance of 550 feet from the mine, thus covering the part favoured by Dr. Fisher for extension of the lode channel. Later the survey was extended a similar distance to the south-west and the north-eastern part was extended a further 150 feet. Methods used comprised geomagnetic, spontaneous, polarisation, electro-magnetic and potential ratio. Traverses were placed at 50 feet intervals and observations by the various methods were made at intervals of 25 feet and, in some parts, at closer intervals. The results of this survey are discussed herein.

A visit of inspection to the Lakes Entrance Shaft, with the object of making a collection of fossils from the sediments already excavated, was made on the 17th and 18th of December. The list of fossils recognised is fairly comprehensive but for the reasons stated it consists chiefly of small forms obtained by washing down the sandy marls. The approximate depths at which the various palaeontological horizons were encountered in the shaft are given below, the sequence and lithology of the beds being identical with that proved in all bores in the vicinity.
