Footnotes:
- 1
- During 2010 the management structure in mining was revised into four business units. Karee includes the shafts K3, 1B and 4B and will also include K4 once production commences. Westerns comprises Rowland, Newman and ore purchases from W1. Middelkraal represents Hossy and Saffy. Easterns includes E1, E2 and E3.
- 2
- Pandora attributable tonnes mined includes Lonmin’s share (42.5%) of the total tonnes mined on the Pandora joint venture.
- 3
- Tonnes milled excludes slag milling.
- 4
- Lonmin purchases 100% of the ore produced by the Pandora joint venture for onward processing which is included in downstream operating statistics.
- 5
- Tonnes milled and derived metal in concentrate from third-party ore purchases.
- 6
- Milled head grade is the grammes per tonne (5PGE+Au) value contained in the tonnes milled and fed into the concentrator from the mines (excluding slag milled).
- 7
- Recovery rate in the concentrators is the total content produced divided by the total content milled (excluding slag).
- 8
- Metals in concentrate includes slag and has been calculated using industry standard downstream processing losses.
- 9
- Corresponds to contained base metals in concentrate.
