AUSTRALIAN STOCK EXCHANGE AND MEDIA RELEASE
EXCELLENT EXPLORATION RESULTS FROM PROMINENT HILL AND GOLDEN GROVE
Initial results received from near mine exploration drilling at Oxiana’s Prominent Hill Project in South
Australia and Golden Grove Operations in Western Australia have highlighted potential for significant
expansions to resources at both sites.
At Prominent Hill the first two diamond core holes of an exploration drilling program, aimed at significantly
expanding the size of the deposit and assessing underground mining options, have intersected wide intervals of
high tenor copper-gold and gold-only mineralisation, 400-500 metres beneath the current resource. Mineralisation
remains open at depth.
Better down hole copper-gold intervals reporting from chalcocite and bornite mineralised hematite breccias include
HOLE D276 28 metres @ 2.1% Copper and 0.6g/t Gold
17 metres @ 1.8% Copper and 0.6g/t Gold
135 metres @ 1.5% Copper and 1.0g/t Gold
HOLE D277 62 metres @ 1.4% Copper and 0.8g/t Gold
Wide intervals of 1-2 g/t gold-only mineralisation occur both within, and peripheral to, the copper-gold system in
both holes. Full results are currently being compiled and assessed. A further release with sections will follow when
this work is complete.
At Golden Grove, drilling beneath the Scuddles mine, where Oxiana is recommencing copper production in 2007,
has intersected 46m of massive sulphide with sphalerite (Zinc sulphide) near the top of the intersection and
chalcopyrite (copper sulphide) throughout. These sulphides are approximately 200m below a 1996 hole which
returned 4m grading 19.5% Zinc and the sulphide zone appears to have a vertical extent approaching 400m with
no defined base at present. The lateral extent of the zone remains untested. Sampling and assaying of the entire
sulphide interval is being expedited and full results will be released as they become available in early 2007.
Exploration programs to extend the resource bases at Prominent Hill and Golden Grove will continue throughout
2007 using some eight drill rigs.

* Both Prominent Hill holes are diamond core in mineralised intervals and collared at 60/000. Hole D276 is drilled on section 5450E and D277 on section
5800E. True mineralised widths are approximately 0.6 times down hole interval. Sampling and assaying protocols for Prominent Hill are included in the
Prominent Hill Resource Statement for 30 June 2006. Refer Oxiana website.
Within this statement references to Resources and exploration results have been approved for release by Mr A. Manini BSc(Hons), FAusIMM who is a
Competent Person as defined by the JORC Code (2004). He has consented to the inclusion of the material in the form and context in which it appears.
