Notes on the mica deposit, Hundred of Para Wirra, County of Adelaide, South Australia. Mineral resources and principle workings are described.

Recently, it was desired for engineering and other purposes to test the micaceous marls and the glauconitic sandstone below the bottom of the shaft. It was decided to put down a diamond drill hole and to use the cores for necessary testing. This report deals mainly with the examination of the cores of glauconitic sandstone obtained from the drill hole. An attempt has been made to correlate much of the available data on the Lakes Entrance field which has a bearing on the Lakes Entrance oil project, and to provide a summary of the occurrence and distribution of oil in the glauconitic sandstone. Finally the report includes a critical examination of the factors influencing the recovery of oil from the glauconitic sandstone by horizontal oil wells, and an estimate of the percentage of oil which might be recoverable from a given area at Lakes Entrance.

A total of 16 rotary cored bores were sunk by the Bureau in Portions 14, 15, 16 and 17, Parish of Wallarah, Northumberland County, 5 miles south of Swansea. Approximately 1,100 ft. of "Test and Define" drilling proved a possible maximum of 960,000 tons of coal, or a minimum of 750,000 tons in the Wallarah Seam under an average overburden coal ratio 5:1. The overburden is mainly conglomerate. The geology of the area and mining are discussed in this report. The results of drilling are detailed in the accompanying plates, stratigraphic logs, and descriptive bore logs of the Swansea South area.

The Cobar mining field was examined between August, 1946 and June, 1947. Attention was concentrated on the operating mines, viz. New Occidental, New Cobar and Chesney. New Occidental Gold Mines, N.L. owns all three deposits and had requested assistance from the Commonwealth Government to search for new orebodies on their leases. It had previously been recognised that each of these orebodies lay close to a sharp contact between fine-grained and coarse-grained sediments. Of particular interest are the portions of the contact which have been subjected to minor folding, because, immediately to the south of these folds, fracturing favourable for ore localisation has developed. The geological examination was carried out in conjunction with the Geological Survey, Mines Department, New South Wales. Surface and detailed underground mapping were carried out. A preliminary magnetic survey of part of the field was carried out by the Geophysical Section during the first half of 1947. A special study of the New Cobar Mine and the plans of that deposit were made by Dallwitz, Fleischman and Ivanac. This report provides a comprehensive overview of the situation, topography, history, structural geology and general geology of the area. Detailed descriptions are given of the history, workings, orebodies, and structure of each individual deposit. Various accompanying plans of the mines and the Cobar mineral field are included.

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

This Summary Report provides an overview of the Regional Hydrogeological Characterisation of the Laura Basin, Queensland, Technical Report (GeoCat number 78881).

On Saturday, 20th September, we visited the Chemistry Department, Crawley, Western Australia, and saw the experimental plant erected for the treatment of Lake Campion alunite. The process was discussed with Professor Bayliss and Mr. H. Bowley, Government Mineralogist and Assayer. On the morning of Monday, 22nd September, we met the Minister for Mines, State Officials and Messrs. F.B. Norwood and L. Gibbons at the Mines Department, Perth. At this meeting the Whim Creek and Ravensthorpe (Phillips River) copper areas were discussed. On the afternoon of the 22nd we met the Aluminium Panel at the Department of Industry and discussed the Lake Campion proposals. On Tuesday 23rd, lateritic bauxites were examined as several localities on the Darling Range and at Toodyay. Following is a review of the matters discussed in Western Australia.

A report on the Montana silver-lead mine, Zeehan, Tasmania.

King Island is situated at the western end of Bass Strait. The scheelite deposits at Grassy were discovered by Mr. T. Farrell about 1913. A new Company - King Island Scheelite N.L. was formed and commenced operations during 1938 and results of their operations to the 31st October, 1941 show: [see record for complete table]. The present production (based on 1941 figures) is 30,000 tons of ore per annum from which 200 tons of scheelite concentrate is obtained. Geology, mining operations, milling practice, and recommendations for testing and development are discussed.

Terrex Seismic was contracted by ANSIR to conduct seismic recording operations for Ballarat Goldfields NL to acquire approximately ten (10) kilometers of high resolution 2D data within the Ballarat region of Victoria. Recording commenced on the 8th May 2006 and was completed 3 days later on the 11th May 2006. The acquisition area of the Ballarat High-Res 2D was situated approximately eight (8) kilometers south of the township of Ballarat.
