Australia's Identified Mineral Resources is an annual nationwide assessment which takes a long term view of mineral resources likely to be available for mining. The highest category in the national inventory is Economic Demonstrated Resources (EDR), which in essence, combines the Joint Ore Reserve Committee (JORC) Code categories of ore reserves and most of the Measured and Indicated Resources. JORC Code ore reserves of commodities are included for comparison, which provide a short to medium-term view of mineral stocks. The assessment also includes evaluations of long-term trends in mineral resources, world rankings, summaries of significant exploration results, and brief reviews of mining industry developments. This entry is for the revised (minor edits - 2014) version of AIMR 2011 GeoCat #73703.

The critical success factors which control hydrocarbon prospectivity in the Otway Basin have been investigated using petroleum systems approaches. Greater than 99% of the hydrocarbon inventory within the Victorian Otway Basin has been sourced from Austral 2 (Albian-Aptian) source rocks and these accumulations are typically located either within, or within approximately 3,000 m of source rock kitchens which are at peak thermal maturity at present day. Importantly, the zones of greatest prospectivity are located where these source rocks have been actively generating and expelling hydrocarbons throughout the Late Tertiary, primarily as a result of sediment loading associated with progradation of the Heytesbury shelfal carbonates. This peak generation window occurs at an average depth of approximately 2,500-3,500 m 'sub-mud' across much of the basin, which has allowed prospective hydrocarbon fairways to be mapped out, thereby highlighting areas of greatest prospectivity. It is believed that the spatial proximity of the actively generating source rocks to the accumulations is due to several factors, which includes overall poor fault seal in the basin (success cases occur where charge rate exceeds leakage rate) and relatively complex and tortuous migration fairways (which means that large volumes of hydrocarbons are only focussed and migrate for relatively short distances). etc

Australia's Identified Mineral Resources 2010 presents estimates of Australia's mineral resources at end of December 2009 for all major and several minor mineral commodities (Table 1) based on published and unpublished data available to Geoscience Australia. These resource estimates provide a long term view of what is likely to be mined. They are compared with national totals of ore reserves for each commodity, which provides the industry view of what is likely to be mined in the short to medium term. Mine production data are based on figures from the Australian Bureau of Agricultural and Resource Economics and Sciences. World ranking of Australia's mineral resources have been calculated mainly from information in publications of the United States Geological Survey. A summary of significant industry developments also is presented. Australia's Identified Mineral Resources 2010 provides information on and analysis of mineral exploration expenditures in Australia for 2008-09 and the calendar year 2009. Trends in expenditure are presented and discussed.

This publication is the successor to Oil and Gas Resources of Australia 2002 and continues as the definitive reference on exploration, development and production of Australia's petroleum resources. It covers exploration, reserves, opportunity for growth of oil and gas resources, development, coalbed methane resources, production, crude oil and shale oil and supporting information and statistics. It includes a forecast of Australia's crude oil and condensate production from 2004 to 2025, and sustainability indicators for petroleum resources. Information on Australia's petroleum data availability is also included and an estimate of Australia's undiscovered oil and gas potential and a review of developments in geological sequestration of carbon dioxide. The Appendices describe wells drilled and seismic surveys carried out in 2003. There is also a chronological listing of offshore and onshore oil and gas discoveries to 2003 listings of all petroleum platforms and pipelines, and a map showing all Australian petroleum exploration and development titles, with a key of title holders and interests as at March 2004. OGRA 2003 provides the background for much of the advice on petroleum resources given to the Australian government and is a key source for petroleum exploration, production and service companies, petroleum engineers and geologists, energy analysts, stockbrokers and share investors.

A deposit of weathered graphic granite at White Rocks, 2 miles south of Queanbeyan, was investigated and the limits of material in it suitable for easily quarryable road metal were determined. The area was divided into two sections: a northern one held for the most part by the Queanbeyan Council, and a southern section at present held privately as a grazing lease. "Indicated" reserves, based on the present quarrying level, of 170,000 cub. yds were established in the northern section. Most of this material will be of the same quality as that being quarried at present; some of the material towards the southern boundary of the lease will however be harder and require more blasting. In the grazing leases "inferred reserves" of 140,000 cub. yds. were delineated. It is expected that this material will be quite suitable for road making but may be slightly inferior in sizing to the material at present being quarried; also it may require more blasting in some portions than the material being quarried at present; it will carry a higher average overburden than the Queanbeyan lease.

In 2000, the US Geological Survey released its World Petroleum Assessment (2000). This assessment provided estimates of the quantities of conventional oil, gas and natural gas liquids that have the potential to be added to reserves in the period 1995-2025. The assessment was for regions outside the United States. For Australia, the Bonaparte, Browse and Gippsland Basins plus the North West SHelf were assessed.

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.

This statement sets out the results of drilling by the Bureau within Swansea Sub-area N.S.W. (J.B.C. plan BG-4). The area investigated comprises approximately 115 acres, about 2 miles south of the township of Swansea in the parish of Wallarah, Country Northumberland. In the Swansea area 'test and define' core drilling by the Bureau has indicated coal reserves of approximately 302,000 tons within the physical limits required for open cut exploitation. This total is made up of more than 87,000 tons in the "Open Cut Block" and 215,000 tons in the "West Block". Proving is recommended for the open cut Block and for the West Block, except that in the latter area the obstruction which will be offered to open cutting by the presence of the P.M.G. cable should be considered before proving is undertaken.

This statement gives the results of a scout drilling campaign conducted by the Bureau at the Kirby's Hill Area of the Western Coalfield of New South Wales. The area investigated comprises approximately 200 acres of the parish of Cullen Bullen in the County of Roxburgh. At Kirby's Hill itself a maximum of about 300 feet of Coal Measure rocks rests on Upper Marine beds, and this is one of the most westerly exposures of the Upper Coal measures. The purpose of scout drilling was to determine the suitability of the Lithgow and Irondale Seams for open cut exploitation.
