Our Coal Resources and Coal Reserves

Our total attributable Coal Resource decreased by ~1%, primarily due to mining. On-mine drilling increasing the level of confidence resulted in material movements between the Coal Resource categories, as noticeably observed at our Mafube mine.

Our total attributable Coal Reserve decreased by ~3%, primarily due to mining depletion and revised LoM plans (LoMPs). A material decrease in Coal Reserves only noted at our Leeuwpan mine (~14%), the result of new drill hole information received as well as layout losses that occurred during the execution of the mine plan.

Other than normal mining depletion, no material changes to the total attributable Coal Resource and Coal Reserve estimates are further reported for any of our operations.

Notes:

• Resource estimations are based on the latest available geological models, which incorporate new validated geological information and, if applicable, revised seam, Resource definitions and Resource classifications. For the 2023 reporting cycle, reported estimates are derived from actual mining up to the end of October, incorporating the planned estimates for November and December.
• Resource and Reserve estimates in our statements are quoted in full, irrespective of Exxaro’s shareholding. Our attributable tonnage is clearly presented in the image above and, when used in our report, always clearly defined as such.
• Rounding off of figures quoted may result in minor computational discrepancies although it is not deemed significant.
