Summary:

Leeuwpan geology.
Two coal seams have been identified at Leeuwpan: top coal seam (TC) and bottom coal seam (BC). BC correlates with the seam 2 (S2) of the Witbank and Highveld coalfields and TC correlates to the seam 4 (S4) and seam 5 (S5). BC qualities are generally higher than TC 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, were 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. Associated with the dolerite intrusion are numerous thin dolerite dyke structures that transgress the stratigraphy. Factors controlling geological and quality continuity are mainly surface weathering, significant variation in seam thickness due to an undulating tillite floor, faulting associated dolerite activity and dolomitic basement, and devolatilisation and weathering due to dolerite intrusions (sills and dykes).

The average total seam thickness at Leeuwpan is 10.9m, with an average raw calorific value of 20.1MJ/kg, raw volatile matter of 18.7% and raw ash content of 31.4% (adb). These qualities require beneficiation for export-quality products.


Mining Methods

  • Truck & Shovel / Loader


Summary:

Leeuwpan is an opencast operation with various Reserves, in various pits, mined simultaneously. Current mining operations are on the OJ (depleted in 2018), OL and OWM Reserves with the introduction of OI Reserves. The OI box-cut was completed in September 2018 and first coal was produced in Q1 2019. The mine uses trucks and shovels for mining-related operations. We estimate that the mine will be in production until 2031, with the mining right lapsing in 2039. Leeuwpan supplies domestic and export markets. The mine is equipped with a rapid rail load-out station, which is the preferred means of coal offtake, although road transport is accommodated.

Summary:

Leeuwpan has two dense medium separator (DMS) plants that beneficiate export thermal coal and a crush-and-stack (CS) plant that handles selectively mined thermal coal, mainly for the local market. The second DMS plant, commissioned in 2016, is operated by Fraser Alexander (FA DMS). The original DMS plant produced a 5 700kcal/kg product whose market ended in Q4 2018, necessitating the change to a 5 300kcal/kg product. The FA DMS, on the other hand, was geared to produce a 5 200kcal/kg product. The CS produced a 4 200kcal/kg product. All three plants produce mainly thermal coal.
