Boring by the Alice Springs Works Department and by Webb Bros. of Mt. Riddock Station showed that subterranean water supplies in the schists and gneisses in this area are usually small in quantity and that the water is brackish. The best chances of obtaining water for the mining fields seems to lie in sinking relatively shallow wells on the creeks and depressions running northward from the Harts Range. These depressions are believed to contain from 30 to 60 ft. of alluvium. Eight possible sites for wells were selected, two being within the foothills of the main range and six at a distance of 1.5 to 2 miles from the foothills of the range. Six of these sites are now being tested by a light hand-boring plant. This plant is expected to penetrate the alluvium quickly and wells will be sunk where favourable results are obtained. The sites selected are within easy reach of the following mines: Jenkins' Mine, The Spotted Tiger Mine, B. Rech's (Rex?) Mine, Hit and Miss Mine, Central Mine and Eldorado Mine.

The deposit is situated 2 miles west from the Scheelite mine at Grassy. A short description of the geology of the area, workings, and mineral occurrence is given in these notes.

The Nelson Bore, which is still in progress and is being drilled with the Commonwealth Rotary plant in collaboration with the Victorian Mines Department, has now reached the depth of 3746 feet, with no indication that the basement rock will soon be reached. Unfortunately no bore in Western Victoria or south-eastern South Australia has been drilled to bedrock, consequently no suggestion can be made as to the possible depth at which it will be met in the present bore. The deepest bore in the area to be palaeontologically examined is Knight's Dome, No. 2, Mt. Gambier, South Australia, which reached the depth of 2013 feet, drilling ceasing in carbonaceous sands.

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 principal heavy mineral deposits occur along the stretch of beaches from Ballina to Tweed Heads, in northern New South Wales, though lesser, but still commercial, accumulations are known at least as far south as Coff's Harbour, and north to Southport in Queensland. Beaches at Yamba, Wooli, and at Fingal have been worked out by Porter and Derrick, the principal producers. This report gives an overview of mineral occurrence, and the formation, composition, and origin of the deposits.

The Dundurrabin copper prospect is 3.5 miles northwest of Dundurrabin sawmill and settlement, and 5 miles from Lyringham, which is connected by road to Grafton, Armidale and Dorrigo. The mine is favourably situated with regard to supplies of water and timber. Development consists of an adit to the lode with a cross-cut through it (Plate I), connected to a shaft from the surface on the south wall of the lode. The shaft has been sunk 30 feet below the adit with another cross-cut at that level through the formation. A few pits and costeans have been put down along the strike. Geology, prospects, and recommendations for further work are discussed.

This report is based entirely on the following typewritten report obtained from the Mines Department of Tasmania: Scott, J.B. 'Report on Mineral Leases 79 P/M, 30 P/M, 82 P/M, 83 P/M, 78 P/M, 71 P/M, 64 P/M, 65 P/M, 66 P/M, and 107 P/M, King Island, chartered in the name of the Sea Elephant Prospecting Association, 6th December, 1926'. The Sea Elephant tin deposit is situated about five miles west from the Sea Elephant Bay on the east coast, and 16 miles by road from Currie, the chief port on the west coast. The deposit consists of sand and clay overlying tin-bearing drift. A detailed account of the deposit is provided in this report.

Report on surveys made at Coorabin on 12th and 13th August, 1942. Locations of drill sites and bores, and R.L. values are listed.

The Pink Lakes, also known as Linga Lakes, lie in the Parish of Mamengoroock, Country of Weeah, in north-western Victoria, about 10 miles north-north-east of the small town of Underbool on the Ouyen to Pinnaroo railway (See Fig. 1). The three lakes known as the Pink Lakes that are being worked for salt are Sailor Lake, Lake Crosby and Crescent or Home Lake. The areas of the salt leases are: Sailor Lake leases, 206 acres; Lake Crosby leases, 395 acres; Crescent Lake leases, 311 acres. Portions of the above areas are occupied by the beaches and fore-shores of the lakes, and the total potential salt-bearing surface of the three lakes is actually about 700 acres. In addition to the Pink Lakes above-mentioned there are in the vicinity two other salt lakes viz: (a) Lake Poulton, about 70 acres in area, and two miles west of Lake Crosby, and (b) an un-named lake, here referred to as 'School' Lake, probably rather less than 50 acres in area and situated one mile south of the west end of Crescent Lake. Salt is formed on both these lakes, but Lake Poulton is somewhat difficult of access on the north-east and north, and School Lake is in a Government Reserve and is not available for leasing. The geology and salt resources of the Lakes are outlined. Several proposals, put forward with a view to increasing the yield of salt from Pink Lakes, are discussed herein.

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.
