Excluding a preliminary visit on September 22nd, four days, November 20th - 23rd was spent on the property. In company with Mr. F. Hanlon of the New South Wales Geological Survey, the surface in the vicinity of the lode outcrops was mapped by plane table on a scale of 100 feet to the inch, and the accessible underground workings mapped in detail and sampled. Cleaning out of the lower "F" Adit had begun at the time of examination, but at the time of writing is not yet complete. This will be mapped at a later date and the results of the examination will be added as an appendix to this report. In addition to the geological and contour map of the surface, plans submitted with this report include a longitudinal section on a scale of 100 feet to an inch, showing the generalised outline of the orebody and the relation between the various outcrops, a more detailed longitudinal section on a scale of 30 feet to an inch showing the distribution of ore values in the principal mineralised section, cross-sections through each of the two principal shafts, and plans of the A, B, and C levels (that of the F level to be prepared later) all on 30 feet to an inch. This report contains notes on the development, general geology, petrology, economic geology, and ore reserves of the Attunga mine.

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.

The Ashford Caves are situated on M.L. 1, Parish of MacIntyre, County of Arrawatta, approximately 12 miles north-westerly from Ashford and 47 miles from rail at Inverell. Claims have been made that there are large reserves of both guano and phosphate rock in these caves. It has been claimed in the Press that 1,200,000 tons of guano are available. The caves were visited on 17.6.43 by the writers in company with the Commonwealth Parliamentary Joint Committee on Rural Industries. The writers' conclusions regarding the guano and phosphate rock deposits are summarised herein.

The available reef exposures were examined under ultra-violet light on September 28th-29th by N.H. Fisher and C.L. Knight, together with Mr. F.N. Hanlon of the New South Wales Geological Survey. A description of the scheelite follows in the report.

The Womobi wolfram mine is situated in M.I.6798 in the Parish of Thologolong, County of Benambra, one mile east of the main Murray Valley Highway and 42 miles by road easterly from Albury. The mine was mapped on September 4th, 1943. The surface was mapped by plane table on Decemeber 1st, 1943, in company with Mr B.P. Utting, and underground mapping brought up to date. The mine is developed by a short adit to the reef, with drives along the reef system 370 feet east and 240 feet west, the west drive being connected to the surface by another adit opening. A connection has been made to the surface from the east drive at 190 feet from the adit, and two short rises were previously in existence 20 feet or so on either side of the adit. At 30 feet in the west drive a winze was sunk 50 feet and a level has been driven along the lode. Stoping is in progress above this level and above the east level.

Langbien's Bore is situated about 12 miles south-east of W.R. Johnston's Bore previously reported upon. The samples examined are from a depth of 50 feet down to 450 feet.

The country rock of the Coimadai antimony orebodies is Lower Ordovician slate and sandstone, with northerly strike and steep westerly dip. It is intruded by narrow east-west striking pre-mineral porphyry dykes, which dip north and are displaced by or in places form the walls of the lode channels. The antimony lodes are lenticular ore-shoots in fault zones which show signs of intense crushing and shearing, the shoots being usually associated with fault intersections or branches. The workings are divided into two sections: No. 1, Draper's, in which the lode system strikes north-northwest and dips 45-55 degrees west, and No. 2, Bondison's, where the strike is east-northeast and the dip 60 degrees to the north. In No. 1 section most of the ore above the adit level has been extracted, but possibly 400 tons of the 5% Sb, ore have been developed below the level, and prospects of further ore are good. Gold values are much higher in No. 2 than in No. 1 section, but few assay data are available with regard to either antimony or gold content.

These deposits, usually known as Hite's Felspar, are situated southeast of Bombala, in M.L.1., Parish of Nalbough, County of Auckland, on the easterly slope of a spur running northward from a sister peak to Wog Mountain. This preliminary note concerns the situation and geology of the felspar and molybdenite deposits at Wog Mountain.

The felspar deposit near Londonderry was examined on Saturday, September 11th, 1943. The deposit has been worked by open cut, the size and shape of which are given in the plan accompanying this report. The report comprises rough notes on mineral assemblage and production figures.
