CML7 Development PlanCML7 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.
