Report on the Rum Jungle uranium deposits

There are three areas so far discovered, each in a different state of development. They are: the East Finniss deposit, which has had a number of costeans and three shafts sunk on it by the present party; the Brown's mine deposit, which has an old shaft and many costeans sunk for copper around 1906; and the Mt. Fitch prospect which has two costeans and an 11 ft. shaft, all old and some distance from the present area of interest. This report deals only with an assessment of the present position and with recommendations for future work in the uranium prospects.

Report on investigation of sulphur deposits, Iamelele-Fangululu district, Fergusson Island, with appendix: Clays resulting from hydrothermal decomposition of volcanic flow rocks

An examination of the deposits took place from 29th June to 13th July, 1950. Very heavy rains hampered the work, but it was possible to make a careful examination of the volcanic areas, and also to gain a general idea of the geological conditions. Some mapping was carried out by compass-pace methods but it is evident that more detailed surveying, with the use of aerial photographs, in order to produce a geological map of the D'Entrecasteaux group, would be worthwhile. An account of this examination and its results is given in this report. The general geology of the area and vegetation are described. The location, nature, extent and destruction of the sulphur deposits are discussed. A note on clays resulting from hydrothermal action upon volcanic flow rocks is appended.

Investigation of potential hydrocarbon contamination sources during the study of Barnicarndy 1, Canning Basin, Western Australia

A regional hydrocarbon prospectivity study was undertaken in the onshore Canning Basin in Western Australia as part of the Exploring for the Future (EFTF) program, an Australian Government initiative dedicated to driving investment in resource exploration. As part of this program, significant work has been carried out to deliver new pre-competitive data including new seismic acquisition, drilling of stratigraphic wells and the geochemical analysis of geological samples recovered from exploration wells. 
A regional, 872 km long 2D seismic line (18GA-KB1) acquired in 2018 by Geoscience Australia (GA) and the Geological Survey of Western Australia (GSWA), images the Kidson Sub-basin of the Canning Basin. In order to provide a test of geological interpretations made from the Kidson seismic survey, a deep stratigraphic well, Barnicarndy 1, was drilled in 2019 in partnership between Geoscience Australia (GA) and the Geological Survey of Western Australia (GSWA) in the Barnicarndy Graben, 67 km west of Telfer, in the South West Canning Basin.
Drilling recovered about 2100 m of continuous core from 580 mRT to the total driller’s depth (TD) of 2680.53 mRT (Normore and Rapaic, 2020). An extensive analytical program was carried out to characterise the lithology, age and depositional environment of these sediments. This included detailed organic geochemistry including isotopic and biomarker analyses of core samples. In order to determine the possible presence of organic contaminants in core samples that may jeopardise interpretation of results, manufactured products used during drilling and sample processing were identified as potential sources of hydrocarbon contamination and were investigated for their hydrocarbon content. In addition, in order to test if any hydrocarbon contamination was occurring due to contact with these manufactured products, water samples from the sumps and surface samples of drill muds from specific depths were collected and analysed as well.

In order to provide a test of geological interpretations made from the Kidson seismic survey, a deep stratigraphic well, Barnicarndy 1, was drilled in 2019 in a partnership between Geoscience Australia (GA) and the Geological Survey of Western Australia (GSWA) in the Barnicarndy Graben, 67 km west of Telfer, in the southwest Canning Basin.
Drilling recovered about 2100 m of continuous core from 580 mRT to the driller’s total depth (TD) of 2680.53 mRT. An extensive analytical program was carried out to characterise the lithology, age and depositional environment of these sediments. This data release presents organic geochemical analyses undertaken on rock extracts obtained from cores selected from the Barnicarndy 1 well. The molecular and stable isotope data carbon and hydrogen will be used to understand the type of organic matter being preserved, the depositional facies and thermal maturity of the Lower Ordovician sedimentary rocks penetrated in this well. This information provides complementary information to other datasets including organic petrological and palynological studies.

Report on the detection by resistivity methods of electrically resistive bodies buried in wet soil at shallow depths

This report deals with the problem of detecting electrically resistive bodies of small size buried at shallow depths in wet soils. Detection was attempted by means of measurements made on the surface of the soil using the electrical resistivity method. The present report can be regarded as an extension of an earlier one (No. 1943/64B). The purpose of the new tests was twofold. Firstly it was proposed to make tests of 'normal' resistivity effects using a constant electrode arrangement and measuring the resistivity at closely spaced points on water saturated soils. The second part of the testing programme was contingent on the first part proving that under saturated conditions soil resistivities were sufficiently constant to warrent an attempt being made at detection. If this condition of constancy existed, it was proposed to extend the work of the tests, reviewed in the previous report, to actual field conditions. This has been done and the present report deals with the results obtained.

Uranium minerals in Australia

The uranium ores of the Mt. Painter area, in South Australia, although inadequately developed or proved, are the most important sources of uranium compounds yet discovered in Australia. Their chemical treatment is relatively easy, whereas the extraction of uranium from certain other recorded ores is difficult. The possibility of the Mt. Painter ores being amenable to appreciable beneficiation is not remote. The uran-ilmenite from Radium Hill (in South Australia) can be considered as a comparable source of uranium only if the ore is processed for its titanium content so as to obtain the uranium as a by-product. This ore is not amenable to significant beneficiation as regards its uranium content. The remaining minerals listed require several modifications of chemical treatment, detailed consideration of which is not yet justified by known reserves of ore. The recovery of the associated uranium can be effected from any uranium ore without substantial modification of the processes advocated for the extraction of the uranium. The methods suggested for the recovery of uranium from these several minerals aim at the production of sodium diuranate which is a convenient intermediate for conversion into other uranium derivatives. The methods discussed were formerly applied on a small commercial scale to the treatment of South Australian uranium ores, particularly those from the Mt. Painter field.

Pacific Sea Level and Geodetic Monitoring Project: Levelling & GNSS Monitoring Survey Report Alofi, Niue, 2019

The Australian Bureau of Meteorology (BoM), Geoscience Australia (GA) and the Pacific Community (SPC) work together on the Australian Aid funded Pacific Sea Level and Geodetic Monitoring Project (PSLGMP). The project is focused on determining the long-term variation in sea level through observation and analysis of changes in the height of the land (using Global Navigation Satellite System (GNSS) data) and changes in the sea level (using tide gauges managed and operated by the BoM. It is the role of GA and SPC to provide information about ‘absolute’ movement of the tide gauge (managed by BoM) using GNSS to continuously monitor land motion and using levelling (SPC) to measure the height difference between the tide gauge and GNSS pillar every 18 months.

Land movement caused by earthquakes, subsidence and surface uplift have an important effect on sea level observations at tide gauges. For example, a tide gauge connected to a pier which is subsiding at a rate of 5 mm per year would be observed as a rate of 5 mm per year of sea level rise at the tide gauge. Because of this, it is important to measure, and account for, the movement of land when measuring ‘absolute’ sea level variation - the change in the sea level relative to the centre of the Earth. Relative sea level variation on the other hand is measured relative to local buildings and landmass around the coastline.
Geoscience Australia’s work enables more accurate 'absolute' sea level estimates by providing observations of land motion which can be accounted for by BoM when analysing the tide gauge data.

This report provides the results of the GNSS monument monitoring survey & high precision level survey completed between the Sea Level Fine Resolution Acoustic Measuring Equipment (SEAFRAME) tide gauge and the GNSS Continuously Operation Reference Station (CORS) in Alofi, Niue, in May of 2019. It also provides an updated height of the tide gauge derived from GNSS time series analysis and precise levelling observations.
