  • Presentation made to the Second US Geological Survey Conference on Reserve Growth. Discussed results of reserve growth study undertaken at Geoscience Australia.

  • The Australian mineral industry is an integral part of the domestic economy with $30.3 billion being generated in export earnings in the 1994-95 fiscal year. As in 1993-94, export earnings from minerals in 1994-95 were just over 60% of the earnings from all commodity exports for the year. The Australian Bureau of Agriculture and Resource Economics (ABARE) forecast that earnings from mineral exports will be $34.6 billion in 1995-96. Without Australia's large and diverse mineral resource base such a major contribution to the economy would not have been possible. Australia ranks as one of the world's leading mineral resource nations. According to estimates published by the United States Bureau of Mines (USBM), Australia is one of the world's top five countries for resources of bauxite, bismuth, cadmium, industrial diamond, gold, mineral sands, lead, lithium, manganese, rare earth oxides, silver, tantalum, and zinc. Australia has the world's fifth largest economic resources of brown coal and the sixth largest of black coal, and has the world's largest low cost uranium resources. In 1995, Economic Demonstrated Resources (EDR) for gold increased substantially and those for bauxite, ilmenite, rutile, zircon, and nickel increased slightly. There was a significant reduction in the EDR for tin and minor reductions for black coal, iron ore, lithium, magnesite and platinum group metals (PGM). Exploration expenditure rose again in 1994-95 to reach $893.3 million. Gold was the main target with an expenditure of $554.5 million, which was 62% of all mineral exploration expenditure. Continued high levels of exploration are essential if Australia is to maintain its mineral resource stock to support a sustainable contribution by the sector to the economy.

  • A medium term forecast of undiscovered hydrocarbon resources for the Bonaparte Basin has been generated by Geoscience Australia and reveals that there is the potential to discover 56 gigalitres (350 million barrels) of oil, 82 billion cubic metres (2.9 trillion cubic feet) of gas, and 18 gigalitres (115 million barrels) of condensate in the next ten to fifteen years.

  • How much oil and gas remains to be discovered? At the Australian Petroleum Production and Exploration Association (APPEA) Conference in Hobart in 2001, Dr Trevor Powell, Chief of the Petroleum and Marine Division, delivered a paper discussing the future of Australia?s hydrocarbon production1. Australia has enjoyed a high level of self-sufficiency for its liquid hydrocarbon requirements but forecasts of future production suggest that as early as 2005, the level of production will drop by about 33% and by 2010, production will be down by about 50%. This production forecast includes forecast production from already developed and soon to be developed fields, as well as a component from fields yet to be discovered.

  • Shows operating mineral mines, deposits where development has commenced or where a decision to mine has occurred. Closed mines or mines not currently operating are generally not shown

  • This report deals with the results of 25,000 ft. of boring over an area of 15 sq. miles. Twenty-six coal seams were identified and named. Total reserves of all seams with band-free thickness greater than 4.0 ft. are 200,000,000 tons. Net open-cut reserves (to 9:1 ratio) of 7,500,000 tons over an area of 400 acres were tested and defined on four seams. All work in the Howick Area was done in the period March, 1952, to June, 1953.

  • Gas is a vital and growing part of the Australian and global energy mix. The gas industry is being transformed due to changes in markets and technology that are bringing new gas resources into play. This report builds on the Australian Energy Resource Assessment (AERA) was first published in March 2010 as a supporting document to the Energy White Paper process. The AERA (Geoscience Australia and ABARE, 2010) is a national prospectus for energy resources. It examined Australia's identified and potential energy resources ranging from fossil fuels and uranium to renewable sources. In the two years following the release of the AERA there have been significant changes in gas resources and within the gas market. This report provides an assessment of Australia's gas resources in 2012 and has been released to contribute to the final phase of the Energy White Paper process. The report documents the growth of gas resources and new projects that underpin an increasing role for gas both in Australia and internationally. For example coal seam gas (CSG) reserves have doubled since 2010 and three CSG/liquid natural gas (LNG) projects are now under construction, In addition, major new offshore conventional gas projects have been committed and commenced construction, including Ichthys in the Browse Basin and Prelude, the world's first floating LNG project. And Australia's third export LNG project, Pluto, has commenced operations.

  • Extended review of mineralexploration in Australia in 2010.

  • Wells Limestone, situated 8 miles from Canberra in A.C.T., is a lens of massive limestone in a formation largely consisting of shales of Silurian age. The gently undulating topography and the low relief of the area of outcrop itself do not provide an attractive quarry site, although the stone seems very suitable for use as aggregate. Soil interpretation from shallow bores indicate considerable extensions of the deposit beyond the outcrop. 'Indicated' and 'inferred' reserves of limestone [have] been calculated, although further proving of reserves should be done before it is decided to establish a crushing plant at the deposit.

  • The area tested by drilling comprises approximately 30 acres of the Parish of Cullen Bullen in the County of Roxburgh, and is immediately to the east of the Portland-Mudgee railway line about 1.5 miles northward from Cullen Bullen Station. The purpose of drilling was to test the Irondale and Lithgow seams of the Upper Coal-Measures for thickness and quality, and thus determine whether or not the more detailed investigation of proving is warranted. Seven holes, with an average depth of 116 feet, were drilled by Goldfields Diamond Drilling Co. under contract to the bureau of near sites chosen by the Geological Survey of N.S.W. The total footage drilled was 810 feet and coal-core recovery averaged 89%. Core drilling in the Tyldesley Area has indicated the presence of 41,000 tons of banded high-ash coal in the lower split of the Lithgow Seam. The coal is considered unsuitable for exploitation by open cut methods and a proving campaign is not recommended.
