  • The presence of apatite on the southern portion of Alcoota Station has been known for several years. The locality was visited during October, 1944. Two days were spent in the examination of the deposit and mapping. An account of the locality, geology and mineralisation is provided in this report.

  • On the 5th February, Mr. A. A. McLeod, General Superintendent of King Island Scheelite, N.L., telegraphed that it was desired to obtain further information about the ore structure to the north-east of cross-section line 13, and suggested the drilling of two diamond drill holes. Three possible sites and holes were discussed. In response to a request from Mr. McLeod, a visit was paid to the mine on the 26th and 27th ultimo, when returning from Mount Bischoff mine, Tasmania. The whole position regarding the above portion of the deposit and open cut were reconsidered, and problems regarding drilling further west on the northern side were also investigated. A short statement was prepared while at the mine which forms the basis of the remainder of this report.

  • "Greisen Lode" is the name given locally to the foot-wall section of a wider mineralised zone, which will be referred to as the Greisen Orebody in this report. Mining operations have been carried out by tributers in recent years on several portions of the orebody, namely, stoping from the Main Tunnel, stoping from an adit-crosscut driven from the No. 4 Gossan Bench, and some stoping operations from a level above the latter bench. During the past three months a level has been driven for 260 feet westwards from the Main Tunnel to prospect the orebody at this level and develop it for mining. Over the past few weeks a detailed geological examination of the orebody has been made and the area involved mapped on a scale of 20 feet to an inch by means of plane table and alidade.

  • Gypsum has been found in all the states of the Commonwealth, but, as far as known at present, deposits of commercial importance are limited to New South Wales, Victoria, South Australia and Western Australia. South Australia is the major producer and provides approximately 80 percent of the total Australian production. An account of gypsum deposits and occurrence by state is given in this report.

  • During the period August 1942 - August 1943, a boring campaign was conducted in the Coorabin section of the coalfield by the Commonwealth Coal Commission. The boring was done by the Water Conservation and Irrigation Commission of New South Wales under the supervision of the Mineral Resources Survey Branch of the Department of Supply and Shipping. When the Coal Commission withdrew, and before the plant was removed from the field, an additional bore was put down by the Department of Supply and Shipping in the Oaklands section of the field. This report contains the results of analyses of the bores.

  • The Curragundi Bore is situated in Portion 15, Ph. Gingham, County Benarba, 12 miles east of Four Posts No. 2 Bore and 11 miles west of Midkin No. 3 Bore. It is about 40 miles southeast of Boronga No. 2 Bore reported upon 30/5/42. The samples examined for micro-fauna were taken from the depth of 50 feet down to 2107 feet 6 inches. The results of this micro-examination are recorded in this report.

  • The Wilks Creek wolfram mine is situated in the parish of Steavenson, county of Anglesey in central Victoria. It is approximately 4 miles south from the small town of Marysville, a popular tourist resort, and 61 miles by road northeast from Melbourne. Underground and surface mapping was carried out on the 23rd and 24th November, 1943, with compass, tape and Abney level. This report comprises an overview of production history, general geology, economic geology and ore reserves.

  • A brief report on the occurrence of beryl on Yinnietharra Station, Western Australia was prepared following a visit to the locality in December 1948. That report referred to three deposits: 1) 0.25 to 0.5 mile N.25°W. from The Cairn; 2)0.25 mile S.60°E from the Mica King mine; 3) Rowe's mine, 2 miles southeast from Morrissey Hill. The report stated that 20 or 30 tons of detrital beryl in large pieces could be picked from the surface with ease. It was pointed out that by collecting small pieces and wider search the immediately available tonnage might be doubled. In June 1944, the first two of the above deposits were again visited, as was one on Bidgemia Station not seen on the previous occasion.

  • In 1935 Mr. F. Blake of the Geological Survey of Tasmania visited Cape Barren Island in connection with the underground water supply at Franklin Village which is situated on Sanford Bay in the northwest part of the island. He collected a small sample of fossiliferous limestone which he forwarded to the late Mr. F. Chapman who was then Commonwealth Palaeontologist. No examination of the material was made at the time. Recently it came under the notice of the writer who has made a detailed microscopic examination of it. The results of the examination are recorded in this report.

  • Results of a micro-faunal examination of samples from bores Nos. 188, 195, 208, and 213, parish of Maryvale, Victoria.
