SUMMARY OF FINDINGS
MINERAL EXPLORATION (OTHER THAN FOR PETROLEUM)
TREND ESTIMATES
The trend estimate for total mineral exploration expenditure increased by 4.5% to $249.2m in the December quarter 2004. The estimate has risen in the last five quarters and is now 33.3% higher than the December quarter 2003 estimate.
Western Australia had the largest increase this quarter (of $8.2m or 5.8%), while Victoria had the largest decrease (of $1.5m or 12.2%).
The trend estimate for metres drilled has been increasing for the past five quarters. The current estimate is now 31.8% higher than the December quarter estimate for last year.
MINERAL EXPLORATION (OTHER THAN FOR PETROLEUM)
EXPLORATION EXPENDITURE
The seasonally adjusted estimate of mineral exploration expenditure decreased by $3.1m (1.3%) this quarter. Victoria had the largest decrease (of $4.2m or 29.8%), while Western Australia had the largest increase (of $1.5m or 1.0%).
In original terms, mineral exploration expenditure increased by $9.7m (3.9%). This increase was dominated by exploration on areas of new deposits, which increased by $9.4m (9.6%). Expenditure on areas of existing deposits increased by $0.3m (0.2%).
In original terms, the largest increase by minerals sought came from expenditure on nickel and cobalt exploration (up $12.4m or 22.9%, with most of the increase coming from Western Australia) and iron ore (up $5.3m or 17.8%). The largest decrease was for exploration on gold, which fell by $13.1m (11.9%).

MINERAL EXPLORATION (OTHER THAN FOR PETROLEUM)
METRES DRILLED
In seasonally adjusted terms, total metres drilled decreased by 4.9% in the December quarter 2004 (down 14.3% in original terms). The seasonally adjusted downturn was due to a decrease in drilling in areas of new deposits (down 32.9%), while drilling in areas of existing deposits increased by 2.1%.

PETROLEUM EXPLORATION EXPENDITURE
OVERVIEW
Expenditure on petroleum exploration for the December quarter 2004 increased by $76.1m (36.2%) to $286.6m.
Expenditure on exploration on production leases decreased (by $4.0m), while exploration on all other areas increased significantly by $80.1m or 53.0% this quarter.
Offshore exploration had a strong increase of $74.8m (54.7%), while onshore exploration expenditure increased by $1.4m (1.9%).
REGIONAL DATA
In the December quarter 2004 most states showed a rise in petroleum exploration expenditure. Victoria had the largest rise of $49.0m. Western Australia recorded the largest decrease of $16.6m (12.8%).
