About Tharisa Platinum Mine

"Tharisa Minerals is 74% owned by Tharisa and is uniquely positioned as the world's only co-producers of both PGM and chrome concentrates. Tharisa Minerals' core asset is the Tharisa Mine, which is situated on South Africa's Western Limb of the Bushveld Complex - host to more than 70% of the world's platinum and chrome resources [Source:].

Business Needs

As Tharisa Mine is the largest known single chrome resource deposit in the world, the Group is was positioned to benefit from the projected growth in demand for chrome, which is primarily used in stainless steel manufacturing. The Tharisa Mine expansion project would ultimately process 3.6-million tons of ROM (run-of-mine) ore a year.
