It incorporates exploration, mining, processing and the beneficiation, marketing, sales and logistics of PGMs and chrome concentrates, using innovation and technology as enablers. Its principal operating asset is the multi-generational Tharisa Mine, located in the south-western limb of the Bushveld Complex, South Africa. Tharisa is also developing the Karo Platinum Project, a low-cost, open- pit PGM asset located on the Great Dyke in Zimbabwe, while simultaneously focusing on beneficiation in the form of chrome and PGM alloys. A 15-year Power Purchase Agreement with Etana for the procurement of wheeled renewable energy and a 40 MW solar project under construction will ensure that Tharisa Minerals' drive to reduce its carbon footprint by 30% by 2030 is well within reach, forming a major part of a roadmap to become net carbon neutral by 2050. Redox One is accelerating the development of a proprietary iron chromium redox flow long-duration battery utilising the commodities we mine.
