    28. Estimated Project Costs – Stage 1 • Acquisition & Corporate $ 4.9m • Infrastructure $ 5.9m • Mine Development $ 6.9m • Mine Operating $ 4.6m • Stage 2 Feasibility $ 2.0m • Subtotal $ 24.3m • Stage 1 Revenue $ 5.6m • Total $ 18.7m

    29. CML7 Development Plan Stage 1 > Kintore decline to upper part of Western Mineralisation - Initial stope trial of 120,000t > Infill drilling of Western Mineralisation, zinc lodes and remnant lead lodes Stage 2 > Development for sustained 500,000 tpa production from Western Mineralisation - metal output of 23,000t zinc, 17,000t lead and 560,000oz silver > Continued infill drilling of resource targets Stage 3 > Expansion into lodes in southern and northern areas of CML7 via declines from Kintore and Blackwoods pits respectively > Resource upgrade to support expansion to 1 million t.p.a.

    30. ExpectedProject Schedule • Data Analysis, Drilling Feb 01 - June 01 • Initial Mining Approval, Equity Funding May 01 - Sept 01 • Decline Development Dec 01 - Jun 02 • Stage 1 Production (120,000t) Jun 02 - Dec 02 • Project Expansion Feasibility & Funding Jul 02 - Sept 02 • Stage 2 Expansion (500,000tpa) Feb 03 - Oct 03

    35. Summary - CML7 • Revisiting major orebody • Existing drilled resource • Established infrastructure • Continuous mining lease • No land title issues likely • Low capital entry to production • Early cash flow projected

    36. Expected Timetable • Marketing June - August • Prospectus issued September • AIM listing October
