Exxaro initiated the Leeuwpan divestment process as part of its ongoing portfolio optimisation strategy to ensure the future resilience of its coal business. Unfortunately, progress on the divestment stalled and the process was stopped in the third quarter of 2022 to ensure stability at the mine. |

Summary:
Leeuwpan mine is in the Delmas coalfield, on the western border of the Witbank coalfield. The geology within the Delmas coalfield is similar to that of the Witbank coalfield.
Like the Witbank coalfield, the Delmas coalfield has up to five coal seams in the middle Ecca group sediments of the Karoo supergroup. The Karoo sequence in the area is represented by the Dwyka formation and the middle Ecca with little or no lower Ecca development. The middle Ecca sequence of coal horizons, interbedded with sediments, is highly truncated due to erosion with minor areas where the full sequence is developed. The basement is generally the Malmani dolomites from the Transvaal supergroup.
Are identified two coal seams at Leeuwpan: top coal seam and bottom coal seam. The bottom coal seam correlates with the S2 of the Witbank and Highveld coalfields and the top coal seam correlates with S4 and S5. The bottom coal seam qualities are generally higher than the top coal seam qualities.
The coal seams at Leeuwpan are primarily interbedded with sandstone, shale and carbonaceous shale.
The coal was deposited on glacial sediments of Dwyka tillite, which in turn was deposited on dolomite of the Transvaal supergroup. A significant amount of magma intruded as concordant sills of dolerite in the Karoo strata in the Delmas area. Thin dolerite dyke structures that transgress the stratigraphy are associated with the dolerite intrusion. Factors controlling geological ........
Summary:
Leeuwpan has two operational opencast pits and continually participates in optimisation initiatives. Overburden removal was below budget due to contractor termination and challenges associated with a new mining business partner’s onboarding. This also impacted subsequent pit liberation, which negatively influenced RoM and overall production.
Leeuwpan is an opencast operation with Reserves in various pits mined simultaneously. Current mining operations are on the OL and OI Reserves. The mine uses a conventional truck-and-shovel mining method.

Reserves at December 31, 2022:
Quality cut-offs: Ash =50%, a non-material amount of coal =50% ash may be included to ensure optimised extraction.
Mineral Resources are reported inclusive of Mineral Reserves.
