| • | Rounding of figures may cause computational discrepancies. |
| • | Percentage zinc (% Zn), percentage copper (% Cu), percentage lead (% Pb), grams per tonne silver (Ag g/t), percentage manganese (% Mn) and percentage sulphur (% S). |
| • | Tonnages are quoted in metric tonnes and million tonnes is abbreviated as Mt. |
| • | Reserves are quoted on a RoM Reserve tonnage basis, which represents tonnages delivered to the plant at applicable moisture and quality. |
| • | Inferred Resources in LoMP refer to Inferred Resources considered for the LoMP. |
| • | Estimates are as received from Vedanta Resources at 31 March 2022 and are not audited by Exxaro. |
| • | All changes more than 10% are explained. |
| 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 and refer to March 2022 only. |
| 3 | The percentage difference between 2022 reported RoM and 2021 reported RoM. Brackets signify a decrease. |
| 4 | The decrease is due to mining depletion. |
| 5 | The increase is the result of the completion of multidisciplinary feasibility studies completed during 2021. |
| 6 | The decrease is due to mining and changes to modifying factors. |
