This report represents an up to date analysis of the stratigraphy, structure, gelogical evolution and petroleum prospectivity of the Naturaliste Plateau based on a revised interpretation of seismic reflection data combined with drilling and gelogical sampling results and supported by potential field interpretation.

The map has two sheets. The first sheet shows resources of rare-earth elements by regions. The second sheet shows resources by deposit types.

Review of activity in the Australian minerals industry in 2009-10

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.

Provinces are defined in terms of overlapping packages of rocks related by depositional or emplacement process, time and space (for example a sedimentary basin), and overprints resulting from various metamorphic or deformation events. These provinces and the events which formed them are recorded in Geoscience Australia corporate Oracle databases and linked with spatial data at a nominal 1:1 millon scale in a GIS delivered via the WWW.

Rumbalara is a small siding on the Adelaide-Alice Springs railway line. It is about 120 miles by rail and 143 miles by road south of Alice Springs. The mine is 35 miles by road northeast of the siding. The object of the visit was to determine, if possible, the extent of the deposits and to decide whether they are likely to be able to supply the requirements of the Australian paint industry, particularly during the present war. The period 29th July to 2nd August, 1943, was spent in the field. During this time a plane table survey was made of the deposit and its environs. The underground workings were surveyed by chain and compass. Half a day was also spent at the field on the 18th January, 1944, in collecting specimens and making a brief inspection of new workings.

The Tennyson Uranium prospects, six in number and referred to as prospects 1 to 6, include 15 deposits all apparently too small and too low in grade, at the surface, to be worth working. Five of them (1A, 1F, 2A, 3, and 5) could be expected to yield 9, 25, 8, 15, and 5 to 18 tons of ore per foot of depth. Assay results are available for prospect 2 only. The estimated average grade of the surface material in deposits 2A and 2C, down to a depth of approximately 3 inches, is 0.21 and 0.13 per cent U3O8 respectively. However, the near surface material may be impoverished by leaching, and the grade may improve at depth. The country is hard, and the width of the orebody ranges from 10 inches in deposit 1F to 16 inches, and possibly 52 inches, in deposit 5. Drilling of a typical deposit should establish the type of mineralization, and indicate the change in grade of ore that might be expected below the surface. It is recommended that any drilling undertaken by the Bureau should be on a deposit, discovered by a Bureau party, 1.25 miles south-east of Tennyson's No. 1 prospect. In any case, the commencement of drilling in the Edith River area should be deferred until after inspection of some, at least, of any anomalies indicated by the proposed air-borne survey of 1953.

A report showing, in so far as figures are available, the salient features of the mineral industry just prior to the outbreak of the Second World War.

This report has been written as the result of conversations between the writers and officers of the Joint Coal Board in Sydney, Lithgow and Cessnock, and with similar assistance from the Geological Survey of New South Wales. The writers visited the Western and Northern coalfields during August and inspected most of the operating open-cuts. The results of the enquiries are presented in five tables which are set out at the end of this report and which contain, in statistical form, the greater part of all the information elicited. The text matter of the report is explanatory of the tables and also discusses the methods which have been used in arriving at the estimates of coal reserves. In the ensuing discussion emphasis has been laid on coal reserves available for open-cut mining, and all enquiries directed to the Join Coal Board were concerned with open-cut coal only.
