return on expenditure on new deposits has been disappointing. Geoscience Australia identifies only one gold discovery, three base metal discoveries and one molybdenum discovery from . This decreasing discovery rate is reflected in Australia strongly focused on brownfields drilling, with 63% of expenditure on those targets.

Geochemical Signatures of IntrusionRelated Mineral Systems A related EGRU project, with separate funding, started earlier this year when PhD student, Peter Illig, began field work on his research project: Magma related hydrothermal gold and base metal deposits in the Chillagoe district, NE Queensland. The preliminary findings so far include:
Intrusionrelated — these deposits are commonly polymetallic and can include a range of precious, base metal and speciality metals ( Pb, Zn, Sn, In, Au) in addition to significant silver.

The alkalic goldporphyry deposits of the Cadia district are located in the eastern Lachlan Fold belt of New South Wales, Australia. The district comprises four porphyry deposits (Ridgeway, Cadia Quarry, Cadia Hill and Cadia East – Far East) and two related skarn deposits (Big Cadia and Little Cadia).

The major difference between Crusader and the majority of these intrusionrelated deposits is the abundance of sulfide and quartz; the orebodies at Crusader are sulfide and quartz poor, and Cudepleted, whereas other intrusiverelated orebodies within the Yilgarn Craton are sulfide and quartzrich and are often associated with Cu mineralization ( Duuring et al., 2007).
