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 Tallandoon Antimony mine, known locally as Dalgliesh and Murphy's, is 2 miles northwesterly from Tallandoon store on the main Omeo Highway and just within the northeast boundary of the Parish of Tallandoon, County of Bogong. This record comprises a description of the general geology and geological report on the antimony deposits.

The felspar deposit which is owned and operated by South Australian Silicates Co. Pty. Limited was visited on the 13th September, 1943, in company with Mr. Sampson, Secretary, of the Company and Mr. S.B. Dickinson, Deputy Government Geologist of South Australia. A description of the deposit follows in the report.

Two samples of diatomite were recently received from Broken Hill Pty. Co. Limited for microscopic examination. They were from Nettle Creek, 9 miles north-east of Mt. Garnet and near Innot Hot Springs. The results of the microscopic examination are given in this report.

This summarised account of oil-drilling activities in Australia and New Guinea is given in two parts, first, a summary of past operations, and second, the status of investigations. Part 1 is almost entirely factual. The object has been to present a summary account of actual drilling operations, the results being obtained and the expenditure incurred therein. Part 2 states briefly the position we appear to have reached in the search for oil and summarises any present activity. The notes are given by States and Territories commencing with New Guinea and thence in clockwise order. "New Guinea" means the island of New Guinea and includes the Mandated section of the island as well as Papua.

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.

The Wallendbeen talc workings are situated just east of the Wallendbeen township and railway station in the parish of Wallendoon, County of Harden, New South Wales. The workings, which consist of innumerable pits and shafts, are distributed along a narrow belt of country, usually more than 200 feet wide and extending from approximately 2 miles north to 1/2 mile south of the railway. The main workings at present are at the southern end of the field and the two producing pits were inspected. An examination was also made of a shaft at the northern end of the field. The talc is second-grade material, occurring both massive and schistose and should be referred to as steatite or soapstone. This report provides an overview of the geology and workings of the deposits.

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.
