| ● | Rounding of figures may cause computational discrepancies. |
| ● | All changes more than 10% in the total Resources of an operation are explained. Tonnages are quoted in metric tonnes and million tonnes is abbreviated as Mt. |
| ● | Coal Resources and qualities (raw coal) are quoted on an MTIS and air-dried basis (adb). |
| ● | Coal Resources are quoted inclusive of Coal Resources that have been modified to Coal Reserves unless otherwise stated. |
| ● | Resources inside LoMP refer to MTIS Resources in the LoMP layout. |
| ● | Thickness and quality cut-offs applied at each project or mine are stated in the ancillary section. |
| 1 | Operation refers to operating mine or significant project. The mining methods are opencast (OC) and underground (UG). |
| 2 | Figures are reported at 100%, irrespective of percentage attributable to Exxaro, and refer to 2022 only. |
| 3 | Locality maps are for illustrative purposes only. Detailed maps are provided in the ancillary section. |
| 4 | Raw coal qualities (adb); CV: calorific value (gross), IM: inherent moisture, S: total sulphur and VM: volatile matter. |
| 5 | The percentage difference between 2022 reported MTIS and 2021 reported MTIS. Brackets signify a decrease. |
| 6 | The positive movement between categories and the increase in Resources inside LoMP are the result of new information. |
| 7 | The decrease of 12.5Mt is the result of mining (4.3Mt), model update (~1.5Mt), disposals (~4.5Mt), mining losses (~0.7Mt) and reconciliation (~2.2Mt). |
| 8 | The increase in total and inside LoMP Resources and the positive movement between categories is the result of new information and the inclusion of the Rooipan area (~33Mt). |
| 9 | The positive movement between categories is the result of new information. |
| 10 | The positive movement between categories is the result of new information. |
| 11 | Estimates are received from Anglo American Steelmaking Coal Proprietary Limited and not audited by Exxaro. |
