  • The following report is based on an examination of the mine made by the writer in February, 1947, and on information gained from the Western Australian Geological Survey. The production history, geology, ore reserves, and prospects of the mine are discussed. Four accompanying plans are included.

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

  • 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 occurrence of ferruginous laterite in the vicinity of Moss Vale, Bundanoon and Wingello, County of Camden, has long been known. In order to define any zones enriched in alumina, a subsurface prospecting campaign was undertaken by the Australian Aluminium Production Commission at Wingello during July and August, 1948 and at Ellsmore in the early part of 1949. The results of this investigation and previous work are summarized in this report. Detailed descriptions of the laterite and of the individual deposits are given.

  • Coal outcrops in the bed of a small gully tributary to the Severn River, at a point 7 miles north of the village of Ashford, 36 miles north of Inverell, New South Wales. A small colliery has been developed in the Ashford Seam and worked intermittently until 1925, mainly to supply coal and coke to the Silver Spur mine near Texas, Queensland. The coalfield and extensions to the north and south have been examined by officers of the New South Wales Department of Mines, the Australian Aluminium Production Commission, the Joint Coal Board and others. During March, 1949 a diamond drilling programme was initiated by the Bureau of Mineral Resources, Geology and Geophysics and both geological and geophysical investigation of the area was carried out by the Bureau during the early phases of the drilling campaign. The geology of the area, nature of the coal, and drilling results are discussed in this report. Logs of diamond drill holes and percussion bores sunk by a former lease-holder are given in the appendix.

  • Australian mineral exploration spending in 2006-07 rose by 38% to a record $1,714.6 million of which 36% was spent on the search for new deposits. Spending rose in all States and the Northern Territory with South Australia up by 78% to $260.7 million while Western Australia dominated with 49% of Australian mineral exploration spending. The base metal group was the dominant target accounting for 32% of exploration spending overtaking gold (27%) for the first time since 1983. Exploration results were announced for a wide range of commodities from across the country with the most significant being the announcement of a 38% increase in contained copper in the Olympic Dam deposit, South Australia, and of an initial 4 Moz resource in the Tropicana gold deposit, Western Australia.

  • Australian mineral exploration spending in 2007-081 rose by 41% to a record $2461.4 million2 of which 44% was spent on the search for new deposits3. Spending rose in all States and the Northern Territory; Western Australia dominated with 51% of Australian mineral exploration spending. Base metals were the dominant target with 32% of exploration spending while gold was the major commodity sought with 24% of total spending. Exploration results were announced for a wide range of commodities from across the country with significant increases in resources at the Prominent Hill copper-gold project in South Australia, Cadia gold-copper project in New South Wales, Cloncurry copper and gold project in Queensland and the Solomon iron ore project in Western Australia. High-grade nickel intersections were reported from the Spotted Quoll and Lounge Lizard deposits in Western Australia.

  • Geoscience Australia provides information on the nation's future capacity to produce mineral resources. Australia's Identified Mineral Resources is an annual nation-wide assessment of Australia's ore reserves and mineral resources. All major and a number of minor mineral commodities mined in Australia are assessed. Australia's economic demonstrated resources (EDR) of the following mineral commodities increased during 2005 - bauxite, cobalt, diamond (gem and industrial), iron ore, manganese, nickel, rutile, silver, uranium, zinc and zircon. EDR of black coal, copper, gold and tantalum decreased in the same period. EDR for brown coal, magnesite, molybdenum, niobium, platinum group metals, shale oil, and vanadium remained at levels similar to those reported in 2005. Increases in EDR were due to on-going drilling and evaluation of known deposits resulting in the transfer (re-assessment) of resources from inferred or sub-economic categories into EDR, and discoveries of new deposits or extensions of known deposits. A few mining companies re-estimated ore reserves and mineral resources more conservatively, notably in regard to black coal, to comply with the requirements of the Australasian Code for Reporting of Mineral Resources and Ore Reserves (JORC Code).

  • 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.
