Resources and Reserves

Mimosa

Mimosa holds contiguous mining rights for a total area of 6,590 hectares across the Wedza Complex in the Great Dyke. As at 30 June 2007, Implats owned a 50% shareholding in Mimosa Investments Limited (with Aquarius Platinum Limited owning the remaining 50%).

Underground stoping operations at Mimosa are being conducted by means of mechnanised bord and pillar methods. The mining method is being changed from a combination of semi-mechanised and mechanised sections to a fully mechanised operation.

Notes

The figures in the statement above reflect the total Mineral Resource and Ore Reserve estimates for Mimosa as at 30 June 2007.
Mineral Resources are quoted inclusive of Ore Reserves.
Mineral Resources are quoted before accounting for anticipated pillar losses. Predicted geological losses have been subtracted from the Mineral Resource estimates.
Compared to previous published figures the material differences are:
- Mineral Resources estimates are now quoted at a 1.95m width aligned with the overall conversion of the mining activities from a combination of semi-mechanised and mechanised section to a fully mechanised operation.
- The resultant revised widths impacted on both the tonnage and grade estimated.
- The Mineral Reserve area at South Hill has been extended by some 300m southwards on completion of the phase 5 studies.
- The Mineral Resource estimate for North Hill was revised after incorporation of the assay results from the 2006 drilling campaign. The estimate is now based on the new generation assay database only.
- Rounding-off of numbers may result in minor computational discrepancies.
