The following eleven holes have been drilled: holes Nos. 22-33. Ongoing drilling operations, and the results and conclusions that can be drawn to date are outlined in this report.

In company with Mr. L.A. Richardson an inspection was made of this deposit on Friday, December 4th. The workings were plotted and examined, though these sections off the main drives could not be inspected very thoroughly owing to having no lighting available except matches.

No. 2 Bore, Boronga is situated north of Moree, near the New South Wales - Queensland border. The samples forwarded for microfaunal examination were from between the depths of 25 feet and 2104 feet.

The following notes on the number of the mica mines in the Harts Range area were collected on a recent water survey. They are very incomplete but it is thought that they may be of interest in view of the possibility of stepping up production in this area. Complete data concerning production, etc. of the mines seems to be impossible to obtain.

The relevant portions of letters from Non-Metallics Limited addressed to Mr. J.M. Newman, setting out the reasons for their Application for a Commonwealth Grant, and the details of the Company's position are reproduced here.

Following a request by the Premier of South Australia an inspection of the Leigh Creek Coalfield was made on December 5th to December 8th, 1941. My opinion was sought chiefly on the probability of there being a considerable tonnage of coal available which could be won by open cut mining, preferably from one section of the field, near Telford Siding.

Report on the facts and cost of maintaining and increasing production at the Mount Bischoff tin mine, Waratah, Tasmania.

An overview of the types, occurrence, supply and production of asbestos in Australia, 1942.

Two reports on the Costerfield Gold-Antimony veins have been published. Bulletin No. 50 of the Victorian Geological Survey, by H.S. Whitelaw gives an account of the lodes and workings and of the history of the mine. An excellent description of the reefs and the mineralisation by Dr. F.L. Stillwell appeared in the proceedings of the Australasian Institute of Mining and Metallurgy, New Series, No. 48, 1922. In view of the existence of these publications, repetition of the details of Costerfield history, workings and geological features is avoided as much as possible in this report, and they are merely summarised in order to present the essential facts concerning the mineralised system.
