 mineral rights over 8,662.3 hectares, valid until 2039. Further studies to define mineral reserves and the life of the mine will be undertaken in 20 25. The Vanderbijl iron ore deposit at Thabazimbi, for which the resources are estimated, is located on the northern margin of the Transvaal sub-basin. The Transvaal Supergroup was deposited in an open marine sedimentary basin developed on the Kaapvaal Craton within fluvial, deltaic to marine depositional environments. The iron ore deposits are developed at or close to the transitional contact zone of the combined footwall dolomites and upper transitional shale beds (including the overlying an approximately 15 meter thick chert-rich shale layer) of the Malmani Subgroup and the overlying BIFs of the Penge Formation.
