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.
