Prospective hydrogen production regions of Australia

There is significant interest in Australia, both federally and at the state level, to develop a hydrogen production industry. Australia’s Chief Scientist, Alan Finkel, recently prepared a briefing paper for the COAG Energy Council outlining a road map for hydrogen. It identifies hydrogen has the potential to be a significant source of export revenue for Australia in future years, assist with decarbonising Australia’s economy and could establish Australia as a leader in low emission fuel production.
As part of the ongoing investigations into the hydrogen production potential of Australia, Geoscience Australia has been commissioned by the Department of Industry, Innovation and Science to develop heat maps that show areas with high potential for future hydrogen production. The study is technology agnostic, in that it considers hydrogen production via electrolysis using renewable energy sources and also fossil fuel hydrogen coupled with carbon capture and storage (CCS). The heat maps presented in this work are synthesized from the key individual national-scale datasets that are relevant for hydrogen production. In the case of hydrogen from electrolysis, renewable energy potential and the availability of water are the most important factors, with various infrastructural considerations playing a secondary role. In the case of fossil fuel hydrogen, proximity to gas and coal resources, water and availability of carbon storage sites are the important parameters that control the heat maps.
In this report we present 5 different heat map scenarios, reflecting different assumptions in the geospatial analysis and also reflecting to some degree the different projected timeframes for hydrogen production. The first three scenarios pertain to renewable energy and hydrogen produced by electrolysis. Differences between the three scenarios depend on whether hydrogen is produced near the coastal areas, where infrastructure and water are not issues or whether hydrogen can be produced in inland areas provided water does become a constraining factor.  Assumptions regarding the proximity of a currently connected electrical grid to transport renewable energy also play a large role in the different scenarios. The final two scenarios focus on the potential for fossil fuel hydrogen, coupled with CCS, with the difference between the two scenarios being related to the timeframes for readiness for both fossil fuel production and availability of CO2 storage resources.

Summarised report on ore prospects of mines held by New Occidental Goldmines NL, Cobar, New South Wales

The Great Cobar ore deposit was discovered in 1870. Production commenced in 1871 and since that date mining at Cobar has been more or less continuous. The field has produced copper, gold, and silver to the value of approximately Â£A27,000,000. Cobar has been the most important producer of copper in New South Wales, and in recent years, has also been the most important gold-mining centre. The Zinc Corporation Limited is carrying out, with the aid of the Bureau, an extensive geological and geophysical examination of the area, with the hope of finding other orebodies. The Bureau itself has extended geological mapping over an area of approximately 2,000 square miles in the Cobar-Nymagee-Canbelego district with the ultimate aim of discovering other ore deposits, or even fields of the Cobar type. In the Nymagee district, North Broken Hill Limited is also carrying out, in co-operation with the Bureau, an extensive exploration programme. The history, production, reserves and prospects of the New Occidental, Chesney, and New Cobar mines are discussed in this report.

Preliminary report on geophysical survey to the north of Leigh Creek coalfield, SA

The Leigh Creek Coalfield is approximately 350 miles north of Adelaide. Coal seams of economic importance are known to occur in two basins about 5 miles apart. Immediately to the north of the known coal basins is an area of some hundred or more square miles, much of which is covered by a thin layer of rocks younger than the coal measures. Other coal basins could exist beneath this cover, and it is considered necessary to the sound development of the coalfield as a whole, that the prospecting of this area should be completed at an early date. The present survey was undertaken at the request of the South Australian Government and was carried out during October, November and December, 1947. The report is a preliminary one since the analysis of the results is not complete. However, sufficient work has been done to make possible the selection of sites for test drill holes. The geology of the area, geophysical method and application, results, interpretation, and testing are discussed in this report. The results of the gravimetric survey are shown on an accompanying plan.

The Hutton Creek bore, Queensland

In the search for oil in Queensland, Drillers Limited, a subsidiary of Oil Search Limited, Sydney, put down a deep bore at Hutton Creek near Injune, in the parish of Simmie, county of Westgrove and 60 miles north of Roma. Drilling operations, which began in 1935 and ceased in 1938 when the depth of the bore was 4,688 feet, were carried out with a Commonwealth Government plant. The major part of the drilling was done by the percussion method, but cores were taken at various depths down to 4,678 feet. No samples were received for microscopic examination until the bore reached the depth of 650 feet, but from this depth to the bottom of the bore-hole, 638 samples of cuttings and cores were examined. Findings from a study of these samples are recorded in this report.

Beach sands investigation: the area between the allotment frontages and DC 22, Seashell Avenue to Riviera Road, North Burleigh, Queensland

The area was bored and sampled in May, 1948. Bores were put down to water level, using a post-hole digger. When the sand brought up from the boreholes appeared to contain appreciable quantities of heavy minerals, it was sampled by quartering. Sample weights, volumes, and dry concentrates were determined. Percentage composition of concentrates was determined by grain counting. The estimates of the quantities and grades of heavy mineral concentrates, the quantities of overburden, and the quantities of each of the heavy minerals are tabulated in this report. Data collected in the course of the investigation has been tabulated and is appended. Accompanying locality and section plans have been included.

Preliminary report on the Precambrian rocks of the Lawn Hill, Camooweal and Dobbyn sheets

An area of about 12,000 square miles was mapped in the field seasons 1950-51. It contains four Pre-Cambrian rock groups ranging from Archaeozoic to Uppermost Proterozoic. The main groups in the area, the Mt. Isa and Lawn Hill Groups, are shallow-water geosynclinal sediments involved in a Proterozoic orogeny which resulted in fairly intensive folding along dominantly north-south axes, together with much faulting. The geological features discussed in this report include physiography, topography, stratigraphy, igneous activity, structure, mineral deposits and water supply.

A review of the petroleum prospects of the North West and Fitzroy Basins of Western Australia and suggestions for a future exploration programme.

For the evaluation of the petroleum prospects of a sedimentary basin, the following factors are generally considered. Lithology, mode of deposition, thickness of the sediments contained in the basin, source and reservoir rocks. Facies of the sediments, changes in facies and the trends of such facies changes. Relationship of the various formations to each other - conformity, disconformity, unconformity, regressive and transgressive overlap, erosional gaps and their significance structurally and for accumulation. Direct or indirect evidence for the presence of oil - seepages, traces or showings of bitumen, oil and/or gas existing bores, bituminous character of some of the stratigraphic members. Tectonics - folding (single phase, multiple phase), faulting, tectonic history and its bearing on migration and accumulation of oil. Types of tectonic traps, and stratigraphic traps in relation to folding and faulting (sandy facies near basement uplift, reef formation on crests of rising anticlines, sandy facies in connection with ancient fault lines). Some of these criteria can be applied to the North-West and the Fitzroy Basins, but it is realized that the information available is not complete enough yet to fully discuss all aspects involved. On the other hand it is felt that, at this stage, a brief review of the results already obtained can greatly assist in an outline of a future programme. It will be seen that much emphasis is laid on geophysical work i.e. gravity investigations for the regional aspect of the problem - the configuration of the basins - and seismic investigations of structures which are selected for deep testing. In our opinion the results obtained so far in the North-West Basin, by both types of geophysical work, have clearly demonstrated the soundness of this way of approach

Report on overburden at the King Island scheelite mine

The overburden (or non-scheelite bearing rocks overlying the ore-bearing rocks) at the mine of the King Scheelite N.L. at Grassy include: 1) A layer of windblown sand ranging in thickness up to 30 feet; 2) An irregular layer of non-mineralised rocks occurring in the north-western part of the present workings; 3) Non-mineralised rocks conformably overlying the lode in the southern part of the workings; 4) Overburden dumped on the southern side of the open cut. The problem of the dumping of the overburden is involved in that of the selection of a suitable site for the treatment plant. Under the proposed scheme to increase production a new site will have to be found for the treatment plant that is to be erected.

Preliminary report on an investigation of Mount Langla Volcano

Mount Langla is one of a group of volcanoes which lies on the western end of the island of New Britain. The 3,800 feet cone is on the eastern flank of the ancient volcano, Mount Talawe and is almost due south of the wartime Gloucester airstrip. The original report concerning the signs of increasing activity was made by Father McSweeney of the Kalingi Catholic Mission. Father McSweeney was returning from a trip along the north coast on 12th May, when he noticed condensed steam rising from a new location on the summit of Mount Langla. On a visit to Borgen Bay on 30th May he saw gas bubbles in the sea close to the shoreline adjacent to the small conical hill which lies on the western side of the Bay. At the request of the Government Secretary the writer left Popondetta and flew to Lae on 18th June, and left by trawler the same day to arrive at Kalingi on 20th June. An inspection of the volcano confirmed the recent nature of the increase in gas emission and revealed a number of phenomena which are usually identified as pre-eruption conditions.
