The Hatches Creek wolfram field is situated at the south-east end of the Davenport Ranges approximately 300 miles by road north-north-east of Alice Springs. The present report is written primarily to indicate the amount of ore which may be expected in the principal mines, chiefly by limited development in depth, and to suggest certain lines of prospecting and development which are likely to result in production of ore and which will enable a more confident statement of possibilities to be made at an early date.

This report follows a preliminary report dated 9th September, 1942, and it is not proposed to recapitulate the matter contained therein, although some references to the preliminary report are necessary. The principal purpose of a second visit to the Lakes was to determine accurately the area of useful salt-bearing surface and the nature of the beds. Much evidence confirmatory of the views expressed earlier regarding the structure of the lake beds was noted. However, a plane-table survey revealed that the total extent occupied by recoverable salt is considerably less than a casual inspection would suggest and consists of the following areas, which are shown on the accompanying plan.

The uranium ores of the Mt. Painter area, in South Australia, although inadequately developed or proved, are the most important sources of uranium compounds yet discovered in Australia. Their chemical treatment is relatively easy, whereas the extraction of uranium from certain other recorded ores is difficult. The possibility of the Mt. Painter ores being amenable to appreciable beneficiation is not remote. The uran-ilmenite from Radium Hill (in South Australia) can be considered as a comparable source of uranium only if the ore is processed for its titanium content so as to obtain the uranium as a by-product. This ore is not amenable to significant beneficiation as regards its uranium content. The remaining minerals listed require several modifications of chemical treatment, detailed consideration of which is not yet justified by known reserves of ore. The recovery of the associated uranium can be effected from any uranium ore without substantial modification of the processes advocated for the extraction of the uranium. The methods suggested for the recovery of uranium from these several minerals aim at the production of sodium diuranate which is a convenient intermediate for conversion into other uranium derivatives. The methods discussed were formerly applied on a small commercial scale to the treatment of South Australian uranium ores, particularly those from the Mt. Painter field.

An inspection was made on Sunday, September, 5th of a pegmatite dyke about five miles southeast of Greg-Greg in the Upper Murray district, New South Wales. This report comprises notes on felspar occurrence.

The presence of muscovite on Yinnietharra Station in commercial sizes and qualities has been known since 1913, but little active development was carried out in the locality until 1926, when a syndicate, formed in England, took up leases and began operations. Activity lapsed the following year, but desultory prospecting more recently has led to the production of a few small cases of spotted mica, some of which was sold in Melbourne in the early part of 1942. The deposits described hereunder are shown on the accompanying locality map, Plate 1. At this stage only brief references are made to deposits containing stained and spotted mica unsuitable for critical electrical or radio applications.

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.

The Wymah mine was visited with Dr. Fisher on Wednesday 25th July. Dr. Fisher has recently visited the mine with Dr. Owen and will be presenting notes embodying his observations, hence this report will be very brief and will refer only to features having a bearing on ore reserves.

Phosphate deposits in the vicinity of Canowindra, Molong, Wellington and Borenore were examined in company with members of the Joint Parliamentary Committee on Rural Industries on the 27th and 28th February, 1943. Two slightly different types of deposit occur in these localities. These deposits are described herein.
