1 | Operation refers to 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 2023 only. |
3 | The + symbol is used in instances where the scheduled LoMP extends beyond the expiry of the mining right. In each instance, Exxaro reasonably expects the mining right to be renewed. |
4 | Export refers to export thermal coal except at Grootegeluk mine, where it refers to semi-soft coking coal suitable for the export and inland markets. |
5 | The percentage difference between 2023 reported RoM and 2022 reported RoM. Brackets signify a decrease. |
6 | The mining right lapses in 2025, the LoM is scheduled for an additional 13 years thereafter. The change in the Probable Reserve is due to the update of the LoMP and reconciliation. |
7 | The decrease is the result of new drill hole information received as well as layout losses that occurred during the execution of the mine plan. |
8 | Changes are the result of the movement in the Resource base and exclusion of area due to environmental considerations. |
