Rosebery Mine has traditionally had a rolling mine life of six years. Our exploration program, Project Horizons, commenced work in 2006 and expanded the resource by 65 per cent to 11.7 million tonnes.
The potential for a small zinc resource was identified at the Jupiter prospect near the Rosebery mine.
A pre-feasibility study was carried out in 2007/08 to review the economic merits of renewing the surface facilities at Rosebery. While benefits from replacement of the grinding and flotation circuits at a cost of $125 million were identified, these are not essential in the short-term. The feasibility study will be completed and then the final design and construction phase will be deferred. Work on the new tailings storage facility and the underground ventilation upgrade will continue.
