In 1992-93 the value of mineral exports was $29 748 million, which was almost 63% of all commodity exports for that year.
Australia's gold and base metal resources in the Economic Demonstrated Resources (EDR) category increased significantly in
1993. In contrast, diamond EDR decreased substantially for both industrial and gem categories, but subeconomic resources for
both categories rose sharply. Other major commodities such as bauxite, black coal, brown coal, iron are, manganese ore, mineral
sands and nickel had minor or no change in EDR. During the past year there were successful exploration programs at many known
deposits and in greenfield regions. At a number of mines resources were increased progressively despite mining over an extended
period. Mineral exploration expenditure in Australia rose marginally in 1992-93 to $631.8 million, indicating some recovery
from the downward trend of the last four years. Gold continued to be the main exploration target, attracting 50.7% of the
total 1992-93 expenditure.
