AUSTRALIA’S IDENTIFIED MINERAL RESOURCES 2004 Expenditure Mineral exploration expenditure for a range of commodities is collected quarterly by ABS. The following discussion is based on the survey data for 2002–03 (year ended 30 June 2003) and the first two quarters of 2003–04. Differentiation of exploration spending into commodity groups prior to 1980 is based largely on a breakdown of ABS totals by Geoscience Australia. Australian mineral exploration expenditure rose by 11.4% to $732.6 million in 2002–03 according to the ABS. This was the highest financial year current dollar amount since 1998–99. Spending for calendar year 2003, based on the sum of the ABS four quarterly figures, rose by just over $57 million to $735.3 million. Gold was again the principal commodity sought and its share of total exploration remained steady at 51.7% in 2002–03. While retaining its dominant position, exploration expenditure on gold rose by $47.1 million to $378.4 million (Fig. 2, Table 5) its highest level since 1998–99. Although Western Australia remained dominant in the search for gold its share of spending fell slightly to 70% ($265.6 million). For reasons of confidentiality of data collected for either Victoria or the Northern Territory, or both, ABS has not published exploration expenditures on individual commodities for those jurisdictions, however aggregate spending in the two was $59 million (15.6% of total spending). In other States, spending on gold was: Queensland $24.3 million (6.4%), New South Wales $19.9 million (5.3%), South Australia $8.3 million (2.2%) and Tasmania $1.4 million (0.3%). FIGURE 2.
