  • Rounding of figures may cause computational discrepancies.
  • Tonnages are quoted in metric tonnes and million tonnes is abbreviated as Mt.
  • Inferred Resources inside LoMP refer to Inferred Resources considered for the LoMP. These Resources have not been converted to Reserves.
  • Coal Reserves are quoted on a RoM Reserve tonnage basis, which represents tonnages delivered to the plant at an applicable moisture and quality basis.
  • Saleable Reserve tonnage represents the product tonnes of coal available for sale on an applicable moisture basis.
  • All changes more than 10% in the total Reserves of an operation are explained.
  • Resource to Reserve modifying factors per operation are stated in the ancillary section.
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.

  • Rounding of figures may cause computational discrepancies.
  • Volatile matter (VM), sulphur (S), ash content (ash) and gross calorific value (CV).
  • Saleable Coal Reserve tonnage represents the product tonnes of coal available for sale on an applicable moisture and air-dried quality basis.
1 Saleable product tonnages are quoted in metric tonnes and million tonnes is abbreviated as Mt.
2 Top coal (TC) and bottom coal (BC).
