| • | Rounding of figures may cause computational discrepancies.
|
| • | Percentage zinc (% Zn), percentage copper (% Cu), percentage lead (% Pb), grams per tonne of silver (Ag g/t), percentage manganese (% Mn) and percentage sulphur (% S). |
| • | Tonnages are quoted in metric tonnes and million tonnes is abbreviated as Mt. |
| • | Estimates are as received from Vedanta Resources at 31 March 2022 and are not audited by Exxaro. |
| • | All changes more than 10% are explained. |
| • | Tonnages are reported on a dry basis. |
| 1 | Operation refers to the BMM operating mine or significant project. Mining method: opencast (OC) or underground (UG). |
| 2 | Figures are reported at 100% irrespective of percentage attributable to Exxaro. |
| 3 | The percentage difference between 2022 reported MTIS and 2021 reported MTIS. Brackets signify a decrease. |
| 4 | The increase is mainly the result of depletion, changes to the models and increased commodity prices applied in the cut-off grade calculations used for reporting. |
| 5 | The increase is mainly the result of increased commodity prices applied in the cut-off grade calculations used for reporting. |
| 6 | Big Syncline is a brownfields exploration project. This is a high-volume, low-grade Zn deposit. The Resource was not updated in 2022 and remains the same as reported in 2021. |
| 7 | The increase is the result of previously reported Reserves being transferred back to Resources and increased commodity prices applied in the cut-off grade calculations used for reporting. |
| 8 | The increase is mainly the result of a revised and updated Resource estimate and increased commodity prices applied in the cut-off grade calculations used for reporting. |
| 9 | The increase is mainly the result of increased commodity prices applied in the cut-off grade calculations used for reporting. |
| 10 | Gamsberg Kloof lies to the east of the Gamsberg open pit and was estimated and declared for the first time in 2022. |
