The Ore Reserve and Mineral Resource estimates were compiled in accordance with The SAMREC Code, 2007 and The JORC Code, 2004 as applicable. The Mineral Resources are reported as inclusive of those Mineral Resources modified to produce the Ore Reserve figures, i.e. the Ore Reserves are included in the Mineral Resource figures.

The figures reported represent 100% of the Ore Reserves and Mineral Resources. Rounding of figures may cause computational discrepancies.

Mining method: OP = Open Pit, UG = Underground.
Mamatwan tonnages stated as wet metric tonnes. Wessels and GEMCO tonnages stated as dry metric tonnes.

GEMCO – Ore Reserves: Changes are the result of pricing changes (increases) between FY07 and FY08. Culturally significant areas have also been excised from the Ore Reserves (G Quarry rainforest) adjacent to the local community. This excision equates to 3.24Mt of ROM for 1.29Mt of product at 47.6% Mn at a yield of 40%.
(2)
Mamatwan – Ore Reserves: X-Zone included as a reserve.
(3)
Wessels – Ore Reserves: Dilution factors as per Ukwazi Mining were used for the resource to reserve conversion. Note that the reserve estimation includes a fines portion of 24% which defines the difference between ROM and quality product. Changes due to following: Revised structural interpretation and model of the Lower Body; Wessels Mine used to be a high grade mine – mean manganese content for W1Lump being 48%. As a result only this high grade portion was previously declared while a low grade portion, W4Lump at a mean grade of 41.8% manganese, was declared as an exclusive resource,with the selling of this product being dependent on marketing requirements. Positive changes in market conditions now allow for the inclusion of all grades above a cut-off of 37.5% Mn; The traditional W1L at a mean grade of 48% was also adjusted to 47% Mn; Changes also due to mine production depletion.

GEMCO – Mineral Resources: The resource has only been depleted due to mine production.
(5)
Hotazel Manganese Mines: An agreement has been signed between Samancor Manganese and an empowerment consortium Ntsimbintle Mining (Pty) Ltd, but remains subject to government approval. When approved, this transaction allows for the inclusion of part of the Prospecting Rights held by Ntsimbintle into the Wessels and Mamatwan Mining Areas in exchange for 9% of the equity in Hotazel Manganese Mines, thereby adding the resources within the Ntsimbintle Prospecting Right to the Wessels and Mamatwan Mining Rights. The Anglo American share of Wessels and Mamatwan mines (Hotazel Manganese Mines) will consequently drop to 36.4%.
(6)
Mamatwan – Mineral Resources: Mineral Resources have been declared above a 35% Mn cut-off grade and also exclude those resources to be contributed by Ntsimbintle Mining (Pty) Ltd.
(7)
Wessels – Mineral Resources: Changes due to following: Revised structural interpretation and model of the Lower Body; The Upper Body, after extensive evaluation, was added as an Indicated Resource. Changes also due to mine production depletion. Figures exclude those resources to be contributed by Ntsimbintle Mining (Pty) Ltd.
