Kalgoorlie Nickel ProjectKalgoorlie Nickel ProjectAn Emerging World Class Nickel Producer
Annual General Meeting 2004
Forward Looking StatementsForward Looking StatementsThis presentation contains “forward-looking statements”. Such forward-looking statements include, without limitation, (i) estimates of future earnings, the sensitivity of earnings to nickel and other metal prices and foreign exchange rate movements; (ii) estimates of future nickel and other metal production and sales; (iii) estimates of future cash costs; (iv) estimates of future cash flows, the sensitivity of those cash flows to the nickel and other metal prices and foreign exchange rate movements; (v) statements regarding future debt assumptions; (vi) estimates of future capital expenditures and (vii) estimates of resources and statements regarding future drilling programs.Where the Company expresses or implies an expectation or belief as to future events or results, such an expectation or belief is expressed in good faith and believed to have a reasonable basis. However, forward looking statements are subject to risks, uncertainties and other factors which could cause actual results to differ materially from future results expressed, projected or implied by such forward-looking statements. Such risks include, but are not limited to, nickel and other metal price volatility, currency fluctuations, increased projected production costs and variances in ore grade or recovery rates from those assumed in mining plans, as well as political and operational risks, government regulation and judicial outcomes. For a more detailed discussion of such risks and other factors, see the Company’s Annual Report for the year ended 30 June 2004 and Half Year Report for the six months to 31 December 2003 as well as the Company’s other filings. The Company does not undertake any obligation to release publicly any revision to any “forward-looking statement” to reflect events or circumstances after the date of this presentation, or to reflect the occurrence of unanticipated events, except as may be required under applicable securities laws. The Company has recently released the results of an Independent Resources Estimates and Scoping Study. The Company wishes to make it clear that at this stage (i) none of the Company’s Resources have been converted into Reserves and (ii) a bankable feasibility study been yet to be completed on the Kalgoorlie Nickel Project (“KNP”).
JORC Code 1999 Compliance The information in this report that relates to Mineral Resources is based on information compiled by Norman Mathew Longworth, who is a Member of the Australasian Institute of Mining and Metallurgy. Norman Mathew Longworth has sufficient experience which is relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined in the 1999 Edition of the “Australasian Code for Reporting of Mineral Resources and Ore Reserves”. Mr. Longworth is a fulltime employee of Heron Resources Limited, employed as Exploration Director.

SummarySummaryThe KNP has the following key attributes:
ScaleResource acquisition complete – is now the world’s second largest contained nickel resourceAble to support a 50,000tpa Ni-in-conc processing plant over 25 years+
High Grade Mineralogy well suited to screen up gradeLFG of >1.5% for Life of Project
Located in the world’s best region for a major nickel projectLow sovereign riskWell developed infrastructure and mining cultureAble to “piggyback” off the Ravensthorpe experienceProximity to key emerging markets (China and India)
Proven Flow Sheet Similar to Ravensthorpe’s proposed flow sheetOverriding aim of minimising production risk / utilising off-the-shelf technologies
Robust financial profile
Established community leadership
The KNP will be developed into a world class producer of nickel
