Currently viewing: Summarised Group Mineral Resource and Mineral Reserve estimates | Next: Belfast
The reported Mineral Resources and Mineral Reserves remaining as at 31 December 2021 are indicated in this section. Mineral Resource and Mineral Reserve figures are not an inventory of all mineral occurrences drilled or sampled but a realistic record of those, under assumed and justifiable technical and economic conditions, that may be economically extractable currently and in future.
Mineral Resources and Mineral Reserves are reported inclusive of Mineral Resources that have been converted to Mineral Reserves. An exception is reporting for Gamsberg and Black Mountain Mining (BMM) because figures received from Vedanta Resources (JORC Code) represent Mineral Resources excluding Mineral Resources converted to Mineral Reserves.
In addition, we provide Resource estimates within LoMP and insight into all applicable modifying factors. Exxaro includes all estimates directly under its management control and estimates of entities in which Exxaro holds a 25% interest or larger. Mineral Resources and Mineral Reserves are reported at 100% irrespective of the percentage attributable to Exxaro.
Explanations for material changes in year-on-year movements are provided as footnotes in the Mineral Resources and Mineral Reserves tables.

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 2021 only. |
3 | Locality maps are for illustrative purposes only. Detailed maps are provided in the ancillary section. |
4 | The + symbol is used in instances where the scheduled LoMP extends beyond the expiry of the mining right. In each instance, Exxaro has a reasonable expectation that the mining right will be renewed. |
5 | 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. |
6 | The percentage difference between 2021 reported RoM and 2020 reported RoM, and the percentage difference between 2021 reported total saleable tonnes and 2020 reported total saleable tonnes. Brackets signify a negative. |
7 | Movement between categories is primarily the result of stooping areas downgraded to Probable Reserves (~15Mt) without surface ownership. |
8 | Movement from Probable to Proved reflects the change in the Resource. The increase in the LoM year is due to the adjustment in annual RoM volumes. |
9 | Decrease is primarily the result of mining depletion (5.2Mt). |
10 | Increase in Probable is the result of a new mine layout. The increase in the LoM year is due to the adjustment in annual RoM volumes. |
11 | The Coal Reserve is reported as Probable as a result of the lapse of the IPP project development agreement. |

1 | Operation refers to the BMM operating mine or significant project. Mining method: opencast (OC) or underground (UG). |
2 | Figures are reported at 100% irrespective of percentage attributable to Exxaro. |
3 | The increase is mainly the result of changes to wireframes and commodity prices. |
4 | The increase is mainly the result of additional exploration and upgrade of Inferred material to Indicated. |
5 | Big Syncline is a brownfields exploration project. This is a high-volume, low-grade Zn deposit. The increase is the result of changes to Resource reporting criteria with increased commodity prices. |
6 | The decrease is the result of Resources being transferred to Reserves. |
7 | The increase is mainly the result of changes to reporting criteria with increased commodity prices. |
