Following the demerger, Anglo American Platinum became an independent company, was renamed Valterra Platinum Limited in May 2025, and began trading as a standalone business on the Johannesburg Stock Exchange on May 28, 2025.
After the spin-off, Anglo American retained a 19.9% shareholding in Valterra Platinum for a limited period.
In September 2025, Anglo American sold this entire retained stake, completing its exit from Valterra Platinum.
Formed over two billion years ago as a result of multiple injections of magma into the earth’s crust many kilometres below the surface, the Bushveld Complex is geologically unique due to its size, uniformity of its layering and extent of known mineral content. Twickenham is located in the Eastern Limb of the Bushveld Complex, north of the Steelpoort fault. The main economic horizons and PGMs mineralisation are the UG2 and Merensky Reefs. Both reefs subcrop on the property, striking approximately north-north-west/south-south-east at an average dip of 15° to the south-west over a strike length of 16km. The UG2 and Merensky Reefs are separated by approximately 400m of mafic cumulate rocks. The Merensky Reef thickness ranges from 100cm to 200cm, with an average thickness of 140cm. The mineralisation occurs mainly in a poikilitic plagioclase pyroxenite bound by thin chromitite stringers and associated pegmatoidal textures, which contain the highest PGM grades. The UG2 Reef chromitite layer varies in thickness from 30cm to 110cm (average of 62cm), overlain by up to five chromitite stringers varying in thickness from 2mm to 1cm. The immediate footwall of the UG2 Reef is usually a pegmatoidal feldspathic pyroxenite, which varies in thickness from a few centimetres to 200cm, with an average of 60cm. The topography consists of a long valley between the fairly rugged Leolo mountain range, comprising main zone gabbro and gabbro-norites. The tectonic setting is characterised by north-north-east/south-south-west striking dolerite dykes of post-Karoo age and faults. A fairly prominent dyke swarm exists on Paschaskraal farm with individual dyke widths reaching 30m to 40m. Other geological discontinuities impacting the mining horizon are potholes, with rare occurrences of replacement pegmatites of various compositions (sometimes iron rich).
