  • 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 2023 only.
3 Raw coal qualities (adb); CV: calorific value (gross), IM: inherent moisture, S: total sulphur and VM: volatile matter.
4 The percentage difference between 2023 reported MTIS and 2022 reported MTIS. Brackets signify a decrease.
5 The decrease is the result of new information and sterilisation that occurred during mine plan execution.
6 Movements within categories are the result of new information.
7 Independent power producer (IPP).
8 Estimates are received from Anglo American Steelmaking Coal Proprietary Limited and not audited by Exxaro.
