Notes on our operations and projects
Grootegeluk
- Positive outcomes of an external
estimation audit, illustrating the
credibility of the processes
underpinning our estimates
- Production of coking coal
increased but year-on-year RoM
decreased slightly
Thabametsi
- The resource is located immediately adjacent to
our Grootegeluk operation, and we are
considering scenarios that will unlock maximum
value for the integrated Waterberg business
Belfast
- Market to resource flexibility was achieved
through establishing a domestic client base
- Challenges experienced early in the reporting year
were addressed, resulting in exceptional
production performance in Q3/4
- Grade control is a key enabler for mining flexibility
between the various pits at the operation
Leeuwpan
- An optimisation study is in
progress to attain a steady and
consistent RoM supply as the
OL pit nears depletion. The focus
will be primarily on the exploitation
of the remaining OI pit
Matla
- The implementation of the three mine
expansion projects, securing an estimated ~85%
of Matla Coal Reserves, progressed well
- Coal Resources identified through innovative
MRM principals, previously situated outside the
LoM, provided additional pit room and the
necessary flexibility for the mining teams to
alleviate implementation delays
Mafube
- A 50% owned, highly successful joint venture mine
with our partner Thungela Resources
- Focused exploration drilling during the year to
increase geological confidence and progress on
environmental studies enhanced future planning
at the operation
Moranbah
- A 50%-owned, hard-coking coal joint venture development with Anglo American Steelmaking Coal in the Bowen Basin, Queensland, Australia
- The execution of a 33km2 3D seismic survey is currently in progress. On completion, most of the Resource will be covered by 3D seismic surveys and will, in
conjunction with focused drilling, contribute materially to the de-risking of the Coal Resource
Our coal estimates for the reporting year (Resource (Mt)) (Reserve (Mt))
Total attributable Coal Resources
Total attributable Coal Reserves
Our total attributable Coal Resources 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 Reserves decreased by ~3%, primarily due to mining depletion and revised LoM plans. A material decrease in Coal
Reserves only noted at our Leeuwpan mine (~14%) is due to new drill hole information received and layout losses that occurred during mine
plan execution.
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: |
a. |
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. |
b. |
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. |

Rounding off of figures quoted may result in minor computational discrepancies, although it is not deemed significant. |
