Australia's Identified Mineral Resources 2010

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resources at end of December 2009 for all major and several minor mineral commodities (Table 1) based on published and unpublished data available to Geoscience Australia.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.

Australia's Identified Mineral Resources 2009

Australia's Economic Demonstrated Resources (EDR) for the following 18 mineral commodities increased during 2008 - black coal, copper, gold, iron ore, lead, lithium, manganese ore, molybdenum, nickel, niobium, rare earth oxides, silver, tantalum, tungsten, uranium, vanadium, zinc and zircon. In the same period, EDR of nine commodities decreased - brown coal, cobalt, diamonds (gem and industrial), mineral sands (ilmenite and rutile), platinum group elements, shale oil and tin. EDR for antimony, bauxite, cadmium, magnesite, and phosphate rock remained at levels similar to those reported in 2007. World ranking: Australia's EDR of brown coal, mineral sands (rutile and zircon), nickel, silver, uranium, zinc and lead remain the world's largest, while antimony, bauxite, black coal, copper, gold, industrial diamond, iron ore, ilmenite, lithium, manganese ore, niobium, tantalum and vanadium all rank in the top six worldwide. Resource life: Ratios of accessible Economic Demonstrated Resources (AEDR) to current mine production provide indicative estimates of the resource life. AEDR of most of Australia's major commodities can sustain current rates of mine production for many decades. Resource life based on ore reserves is lower, reflecting a shorter term commercial outlook. Over the decade 1997 to 2008 there has been a significant trend towards lower AEDR/production ratio for coal and iron ore, which was the nett result of major increases in production and reassessment of resources. Commodities with resource life of less than 50 years are diamonds (about 10 years at current rates of production), manganese ore (20 years), gold (30 years), zinc (35 years) and lead (40 years). The severe world financial crisis in late 2008 highlighted the fact that a long resource life for a particular commodity is not a guarantee that such resources will continue to be exploited in Australia. In an increasingly globalised and competitive commodity market, multinational mining companies are continually in search of mineral deposits that will offer attractive returns on their investment. Such returns are influenced by the quality of the resources (grade and tonnage) as well as environmental, social and political factors, land access and even the location and scale of the competitor projects - individual mine projects in Australia will be ranked by multinational corporations against the investment returns from other deposits worldwide. Australia's continuing position as a premier mineral producer is dependent on continuing investment in exploration to locate high quality resources and/or to upgrade known deposits in order to make them competitive on the world market, and investment in beneficiation processes to improve metallurgical recoveries. Australia's Identified Mineral Resources 2009 provides information on and analysis of mineral exploration expenditures in Australia for the calendar year 2008. Trends in expenditure are presented and discussed.

Australia's Identified Mineral Resources 2008

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. It includes international rankings, summaries of significant exploration results, brief reviews of mining industry developments, and an analysis of mineral exploration expenditure across the States and Northern Territory. AIMR provides governments, industry, the investment sector and general community with an informed understanding of Australia's known mineral endowment and level of exploration activity. An important objective is to monitor whether resources are being discovered and developed for production at rates sufficient to maintain Australia's position as a major supplier of mineral commodities. Australia's economic demonstrated resources (EDR) for the following 18 mineral commodities increased during 2007 - antimony, bauxite, cobalt, copper, gold, iron ore, manganese ore, ilmenite, rutile, zircon, molybdenum, nickel, rare earths, silver, tungsten, uranium, vanadium and zinc. In the same period, EDR of eight commodities - black coal, cadmium, diamonds (gem and industrial), lead, niobium, phosphate rock, platinum group metals and tantalum decreased. EDR for brown coal, lithium, magnesite, shale oil and tin remained at levels similar to those reported in 2006. 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 the discovery of new deposits or extensions of known deposits. Sustained increases in prices for most metal and mineral commodities over recent years has allowed companies to re-assess the economic viability of lower grade resources and deposits which previously were considered to be uneconomic. Overall this has contributed to an increase in EDR for many metal and mineral commodities.

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. It includes international rankings, summaries of significant exploration results, brief reviews of mining industry developments, and an analysis of mineral exploration expenditure across the States and Northern Territory. AIMR provides governments, industry, the investment sector and general community with an informed understanding of Australia's known mineral endowment and level of exploration activity. An important objective is to monitor whether resources are being discovered and developed for production at rates sufficient to maintain Australia's position as a major supplier of mineral commodities. Australia's economic demonstrated resources (EDR) of the following mineral commodities increased during 2006 - black coal, copper, gold, iron ore, rutile, zircon, platinum group metals, silver, tin, tungsten and vanadium. EDR of bauxite, cobalt, diamond (gem and industrial), lead, manganese, nickel, uranium and zinc decreased in the same period. EDR for brown coal, magnesite, molybdenum, niobium, shale oil and tantalum remained at levels similar to those reported in 2005. Estimates of Australia's resources of coal bed methane gas are reported for the first time in AIMR. 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. Sustained increases in prices for most metal and mineral commodities over recent years has allowed companies re-assess the economic viability of lower grade resources and deposits which were previously considered to be uneconomic. Overall this has contributed to an increase in EDR for many metal and mineral commodities.

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).

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 2004 - bauxite, black coal, copper, gold, iron ore, ilmenite, lead, manganese, rare earth elements, tantalum, tin, uranium and zinc. EDR of cobalt, diamonds (both gem and industrial), lithium, phosphate, rutile, silver, tungsten and zircon decreased during the year. EDR for brown coal, magnesite, molybdenum, nickel, niobium, platinum group metals, shale oil, and vanadium remained at levels similar to those reported in 2003. 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. Newly delineated resources of 1 256 t added to gold's total national inventory, with growth in all east coast mainland states and South Australia. A few mining companies re-estimated ore reserves and mineral resources more conservatively for some commodities to comply with the requirements of the Australasian Code for Reporting of Mineral Resources and Ore Reserves (JORC Code).

Australia's Identified Mineral Resources 2004

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. It includes evaluation of long term trends, international rankings, summaries of significant exploration results, brief interviews of mining industry developments, and an analysis of mineral exploration expenditure across Australia. Australia's economic demonstrated resources (EDR) of the following mineral commodities increased during 2003 bauxite, copper, diamonds (both gem and industrial), ilmenite, lead, nickel, niobium, silver, tantalum, tin, zinc and zircon. EDR of black coal, iron ore, lithium, magnesite, manganese, platinum group metals, rare earth elements, rutile and uranium decreased during the year. EDR for brown coal, cobalt, gold, molybdenum, phosphate rock, shale oil, tungsten and vanadium remained at levels similar to those reported in 2002. Increases in EDR were due to ongoing 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. The large increase in EDR for copper during the year resulted from a re-assessment of measured and indicated resources for Olympic Dam deposit (SA), and the discovery of additional economic resources at Mount Isa and Ernest Henry deposits (Qld). Decreases in EDR of black coal and iron ore during 2003 reflect increased rates of mine production. In addition, mining companies re-estimated their ore reserves and mineral resources more conservatively so as to comply with the requirements of the Australasian Code for Reporting of Mineral Resources and Ore Reserves (JORC Code).
