Resoiling of dredged areas, Bulolo, Territory of New Guinea

At the end of 1945 the area dredged by the Bulolo Gold Dredging Co. Ltd. was 831 hectares. At that time 307 hectares remained to be dredged and of this 227 hectares contained soil which has been shown by soil analysis to be reasonably good. Resoiling would not be practicable on about 70 hectares of this area, as the Company plans to dredge this section twice, first with shallow and then with deep-digging dredges. Similar soil exists on 3-400 hectares classified previously by the Company as marginal ground, but which, since the increase in the Australian price of gold, is now probably quite profitable. This makes the total area that might be suitable for resoiling about 500 hectares compared to 1,281 hectares that either has been dredged or to which for other reasons resoiling is not applicable. Revenue to the Administration from the gold produced at Bulolo is over Â£1,000 per hectare from royalty alone and as most of the area has now been worked it seems questionable whether resoiling is worth further consideration at this stage. No provision was made for resoiling in the terms of the original mining tenements, but the Company's officials have expressed willingness to co-operate in carrying out the wishes of the administration. It has been considered impracticable now to resoil the areas that have been dredged or to rebuild the existing dredges for mechanical resoiling, but if the Department of Internal Territories considers that the matter should be pursued further, the Company might be asked to consider removing soil from the dredge path by bulldozer or other mechanical means and replacing the soil on the flattened out tailings after the dredge has passed; also to provide details of the economics of carrying out a similar scheme on the areas in which values were previously considered to be marginal.

Monazite in beach sand concentrates, Queensland and New South Wales

An earlier reconnaissance survey indicated that monazite is the only likely source of thorium in Australia and further, that the beach sands on the eastern coast for approximately 170 miles on either side of the Queensland-New South Wales border contain by far the largest reserves of monazite. For this reason a special investigation of these sands was conducted. An inspection was made during September, 1944, of the beach sand deposits and of the various plants engaged in the production of concentrates from the sands. Samples were taken, where necessary, to supplement the known information about the composition of the sands and of the different mill products, mainly with a view to ascertaining the distribution and disposal of monazite in the concentrates. The production procedures, disposal practices, and total production of monazite are discussed in this report. An accompanying  locality map is included.

The Storey's Creek mine, Storey's Creek, Tasmania

The Storey's Creek mine is situated about 14 miles by road in a northerly direction from Avoca. Avoca is connected with the State railway system. The lodes contain both wolfram and cassiterite and the mine is at present being worked by Storey's Creek Tin Mining Co. The lodes were discovered at least as early as the eighties and were worked for tin ore. The wolfram content did not become marketable until about 1900. The mine was taken over by a local tribute party and worked successfully until about 1937. Since then the working has been conducted by The Storey's Creek Tin Mining Co. N.L. The production during the past 10 years has been as follows: [see record for table].

The 2018 National Seismic Hazard Assessment for Australia – Data package, maps and grid values

Geoscience Australia, together with contributors from the wider Australian seismology community, has produced a National Seismic Hazard Assessment (NSHA18) that is intended as an update to Geoscience Australia’s 2012 National Seismic Hazard Maps (NSHM12; Burbidge, 2012) and its 2013 update (Leonard et al., 2013).  The update at this time is intended to take advantage of recent developments in earthquake hazard research and to ensure the hazard model uses evidence-based science.  This Geoscience Australia Record provides an overview of the output datasets generated through the development of the NSHA18.  Time-independent, mean seismic design values are calculated on Standards Australia’s AS1170.4 Soil Class Be for the horizontal peak ground acceleration (PGA) and for the geometric mean of the spectral accelerations, Sa(T), for T = 0.1, 0.2, 0.3, 0.5, 1.0, 2.0 and 4.0 s over a 15-km national grid spacing.  Hazard curves and uniform hazard spectra are also calculated for key localities at the10% and 2% probability of exceedance in 50-year hazard levels.  Uniform-probability seismic hazard maps of PGA, in addition to all spectral periods, are provided for 10% and 2% probability of exceedance in 50 years.
A Python script is provided to enable end users to interpolate hazard curve grids and to export site-specific hazard information given an input location and probability of exceedance (in the case of uniform hazard spectra).  Additionally, geographic information system (GIS) datasets are provided to enable end users to view and interrogate the NSHA18 outputs on a spatially enabled platform.
This is the most complete data publication for any previous Australian National Seismic Hazard Assessment.  It is intended to ensure the NSHA18 outputs are openly available, discoverable and accessible to enable end-users to integrate these data into their own applications.

The Arcadia bore, Queensland

Note that this record includes Record 1945/014 by the same author. The Arcadia bore is situated in the parish of Arcadia, county of Westgrove, 85 miles north of Roma and 40 miles north-north-east of Injune. Drilling operations extended from 1936 to 1939 and were carried out by Drillers Limited. The bore was drilled in a large dome structure developed in Triassic and Permian sediments. The Arcadia bore is the second deep bore in Queensland from which a comprehensive series of samples has been examined for their microfaunal content. This examination was carried out on 1,256 samples consisting of drill cuttings taken over every five feet and of cores taken at numerous depths below 4,112 feet. The findings from the examination of these samples are described in this report.

Foraminifera in the Permian rocks of Australia

The presence of foraminifera in the Permian sediments of Australia was recorded as early as 1882. Some systematic work was done up to 1905, but there was no further investigation into these micro-fossils until 1937. A considerable amount of research is still necessary before it can be stated whether or not a definite system of zoning, based on micro-faunas, can be applied to the Permian rocks of Australia. It seems possible, however, that certain species may be characteristic of the Upper and Middle Permian deposits. In the extensive collections of Permian rocks examined from the Hunter River District in New South Wales, assemblages of foraminifera rather than restricted species have proved useful for zonal purposes and this method of zoning should prove valuable when more material is examined from the Permian deposits of other States.

The mineral deposits and mining industry of Papua

Mineral deposits in Papua include those of gold, copper and manganese and from these there has been produced gold; silver; copper, copper matte and copper ore; manganese ore; osmiridium and platinum. The gold has been obtained from alluvial deposits and lodes and from the copper deposits. Silver has been obtained along with the gold, but no separate record of it has been kept. The copper and manganese ores have been obtained from their respective deposits. The osmiridium and platinum have been won during the mining of the alluvial gold deposits. A fairly intensive search has been made for petroleum, but there has not been any commercial production. The total value of the mineral production to 30th June, 1941, is Â£3, 246, 353, the detailed production being as follows: [see table in record].

Review of geophysical surveys in the Wallaroo-Moonta district, South Australia during 1942

The Wallaroo-Moonta copper field offers a challenge to modern geological and geophysical ore-finding methods. After the production of some 338,066 tons of copper valued at over 20 million pounds, large scale mining ceased in 1923. In spite of the present urgent need for copper, investigators have agreed that no good purpose can be served by re-opening the old mines and that any further substantial production from the field depends upon the discovery of new ore-bodies. Since the ore-bearing rocks are almost completely covered by superficial deposits, it is not unreasonable to suppose that there are still undiscovered ore-bodies in the field. Nevertheless some 30,000 feet of diamond drilling have been carried out in the past and the results, generally speaking, have been very poor. This is not surprising, perhaps, when the local nature of ore occurrences and the vast extent of barren country rock is contemplated. It appears that there is a clear task for geological and geophysical methods to select sites where diamond drilling will have the maximum chance of intersecting ore. The masking of the surface geology immediately suggests the application of geophysical methods and in 1929 some work was carried out at Moonta by the Imperial Geophysical experimental Survey. After a limited amount of work this Survey was forced to the conclusion that the field presented greater difficulties to electrical prospecting, owing principally to the screening effect of the saline overburden. Since 1929, however, geophysical technique has progressed considerably, and more is known concerning the physical conditions of the field. In view of the possible prize at stake it was therefore decided early this year to re-open and carry out further geophysical surveys. The work was carried out in close co-operation with the South Australian Mines Department, which had previously made extensive investigations of the structural geology, and had recommended the use of the geophysical methods.

Geological report on the Rumbalara ochre deposits

Rumbalara is a small siding on the Adelaide-Alice Springs railway line. It is about 120 miles by rail and 143 miles by road south of Alice Springs. The mine is 35 miles by road northeast of the siding. The object of the visit was to determine, if possible, the extent of the deposits and to decide whether they are likely to be able to supply the requirements of the Australian paint industry, particularly during the present war. The period 29th July to 2nd August, 1943, was spent in the field. During this time a plane table survey was made of the deposit and its environs. The underground workings were surveyed by chain and compass. Half a day was also spent at the field on the 18th January, 1944, in collecting specimens and making a brief inspection of new workings.
