The Renison Bell tinfield, Tasmania

The discovery of tin ore on the field was made in June, 1890, and for many years work was confined to the alluvial and detrital tin ore. The gossan outcrops of the pyritic tin-bearing ore bodies were not recognised as the source of the detrital tin for some years. During the construction of the Emu Bay Railway in 1900, the railway line necessitated a large cutting on the Renison Bell lease, and exposed the main lode system. Capital was not available for development of the property, and operations were confined to the erection of batteries to treat the detrital matter and oxidised ores which were free-milling. Spasmodic attempts have been made to treat the sulphide ore by precalcination and gravity concentration, and at the present time Renison Associated Tin Fines N.L. are experimenting with the flotation of cassiterite, which is preceded by flotation of the iron sulphides. Inspection of all workings reveal that the area has been carefully searched for all outcropping tin lodes, and mining operations have been more or less confined to selective mining of the oxidised ore and very little of the richer sulphide ore.

Preliminary report on the Greisen orebody, Mt Bischoff tin mine, Tasmania

"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.

Preliminary geophysical survey, Morwell brown coalfield, Victoria

This report deals with the results obtained in tests with the electrical resistivity method on the brown coalfields at Morwell and Traralgon, Victoria, in an attempt to develop a rapid method of determining the presence of the coal and its depth below the surface. These tests were carried out in the latter part of 1943 by the Geophysical Section of the Mineral Resources Survey at the request of the Victorian Electricity Commission. Thirty-four resistivity-electrode separation tests were made over a wide variety of geological sections in the parishes of Maryvale, Hazelwood and Loy Yang. These tests were preceded by a number of tests by specific resistivity made on various types of overburden and on coal exposed in the open cuts at Yallourn. This report discusses the results of these tests although verbal information concerning them has already been made available to the Commission's officers. It will be shown that under certain conditions, the predictions of the depth to coal are reliable within fairly narrow limits while under other conditions the predictions are misleading. It is proposed in the first instance to outline the method and apparatus used in these tests. In addition, it is considered advisable to outline the methods of interpretation employed in order that the conclusions reached will by fully appreciated. In addition to discussing the resistivity results, the report deals briefly with the possibility of using gravity methods on the same prospecting problem. Calculations have been made of gravity anomalies to be expected from certain coal sections and it is shown that under favourable conditions this might prove of value in determining the presence and position of the coal.

Preliminary report on bauxite near Campbell Town, Tasmania

Bauxite deposits on Rosedale, Meadowbank and Riccarton Estates at Campbell Town were tested by shaft-sinking and boring during November and December 1946. Earlier than this the Tasmanian Mines Department had sunk a number of shafts on the deposits, mainly at widely spaced intervals. The work undertaken chiefly consisted of testing between the shafts sunk by the Mines Department so that the interval between the points tested was reduced to 200 feet or less. A few of the old shafts were cleaned out and resampled. The results of the tests at each estate are discussed in this report.

Second report on a collection of fossils from Lakes Entrance shaft, Gippsland, Victoria

This collection of fossils was made by Mr. H.J. Cook, Supervisor of the Lakes Entrance project during December, 1942. It consists chiefly of broken specimens of molluscan shells, the most important being a fragment of large Mitra, Fulgoraria ancilloides (Tate) and an almost complete specimen of Cypraea consobrina (McCoy). The importance of the discovery of the latter species is discussed in the report on my recent visit to the shaft, but the presence of the former (which had previously only been recorded from the Balcombian and has a length of 110 millimetres) in the present collection, again indicates that valuable information has been lost through inadequate sampling of a rich shelly zone in the Kalimnan stage.

The Hutton Creek bore, Queensland

Note that this record includes Record 1945/015 by the same author. In the search for oil in Queensland, Drillers Limited, a subsidiary of Oil Search Limited, Sydney, put down a deep bore at Hutton Creek near Injune, in the parish of Simmie, county of Westgrove and 60 miles north of Roma. Drilling operations, which began in 1935 and ceased in 1938 when the depth of the bore was 4,688 feet, were carried out with a Commonwealth Government plant. The major part of the drilling was done by the percussion method, but cores were taken at various depths down to 4,678 feet. No samples were received for microscopic examination until the bore had reached the depth of 650 feet, but from this depth to the bottom of the bore-hole, 638 samples of cuttings and cores were examined. Core samples were taken at more frequent intervals towards the bottom of the bore-hole than higher up. The results of the study of the cores and cuttings from the bore-holes are described in this report.

The production of sulphuric acid and Portland cement from calcium sulphate and aluminium silicates: the chemical fundamentals

Sulphuric acid may be produced not only from sulphides but also from calcium sulphate, by the use of which portland cement can be manufactured simultaneously with the acid. For the manufacture of sulphuric acid and portland cement from calcium sulphate and aluminium silicates, a mixture of anhydrite, clay, sand, and coke as a reducing agent is usually used. The chemical fundamentals underlying the manufacturing process are discussed in this report. The chemical reactions involved in the production process and the uses of raw materials are described at length.

Report on taxation in the mining industry

This report arises from an application by Tableland Tin Dredging, N.L. that tin mining be exempt, like gold mining, from taxation. A detailed examination was made of the tin-mining industry, the results of which are attached to the Report: Appendix I outlines the economic position of the Australian tin industry, and Appendix II summarises the positions of the individual mines. Since the application was first submitted, amendments to the Act have considerably improved the taxation position of mining companies. During the investigation the conclusion emerged that, notwithstanding the recent decided improvements in taxation as applied to mining, some further improvements seemed desirable. Since it was found inadvisable, on grounds of economics policy, to make a special case for the tin industry,  proposals were put forward for the mining industry as a whole, using data collected from various mines as particular examples of the effects of taxation.

Note on the oil possibilities of the North-West Basin and the Desert Basin

A visit of one month was paid by the writer to the North-West Basin and the Fitzroy area of the Desert Basin. It is largely due to the careful planning of the excursions by the Senior Geologists in charge that a coherent picture of the stratigraphical and tectonical conditions was obtained within the comparatively short time at disposal. This note contains a few remarks on the stratigraphy and tectonics of both areas in connection with oil prospects.

Re-examination of fossils of locality B68 (204 miles west of Djarra) Queensland, with a note on the palaeography of the Middle Cambrian

In the Preliminary Report on Cambrian Fossils (1948/073) collected in the Northern Territory, locality B.68, 20.4 miles west of Djarra, was placed among the localities with the western development of the Middle Cambrian Xystridura-fauna. Mr. P.B. Nye has drawn the writer's attention to the fact that the Djarra locality is in Queensland 90 miles east from the Northern Territory border; i.e. far away from those localities with a typical "western fauna" and near those with an "eastern fauna". A re-examination of the fossils and palaeogeographical interpretation of the locality near Djarra therefore becomes necessary.

Preliminary report: geophysical survey at Cobar, New South Wales

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.
