Abstract
Resource estimates for individual mineral deposits reported by companies using the Joint Ore Reserves Committee Code are compiled in Geoscience Australia's national mineral resources database and used in estimating national resource inventories which are reported in categories of the National Mineral Resources classification system. The national inventory provides a long term national perspective of potentially mineable resources and the results are published online in 'Australia's Identified Mineral Resources'. Analyses of resource trends show that growth in Australia's resources have generally been strongly influenced by: - discoveries of new deposits, and extensions of resources at known deposits, - advances in metallurgical techniques and mining methods which have stimulated the exploration and development of new ore types and low grade deposits previously considered uneconomic, - availability of cheaper energy, - increases in prices of mineral commodities driven largely by the massive demand from China. From the early 1970s, Australia's iron ore mines have been based on large resources of direct shipping hematite ores in the Hamersley Basin. From 2003, Australia's Economic Demonstrated Resources (EDR) of iron ore grew to record levels as increased demand for iron ore generated renewed interest in magnetite ores. As a result, large increases in magnetite resources were recorded as development of large magnetite deposits in the Pilbara (Sino Iron project) and mid-west regions of WA (eg Karara deposit) commenced. Trends in Australia's EDR of black coal, gold and other major commodities are discussed.
