About Tharisa - delivering on expansion and growth opportunities, commercialising technology solutions

Tharisa is an integrated resource group playing a pivotal role in the global energy transition and the decarbonisation of economies. Leveraging innovation and technology, Tharisa covers the entire value chain - exploration, mining, processing, beneficiation, marketing, sales, and logistics - for PGMs and chrome concentrates. The low cost, multigenerational Tharisa Mine is located on the southwestern limb of the Bushveld Complex, South Africa, the largest source of PGMs and chrome globally. Development of the Karo Platinum Project, a tier-one PGM project on Zimbabwe's Great Dyke, further reinforces Tharisa's growth strategy. Investments in downstream beneficiation, including proven chrome and PGM alloy production, will add significant value when commercialised. Tharisa is committed to reducing carbon emissions by 30% by 2030 and the sustainability roadmap targets net carbon neutrality by 2050. Through Redox One, Tharisa is advancing proprietary iron-chromium redox flow battery technology, utilising the very commodities it mines to support long-duration energy storage - a key component in the transition to renewable energy.

Tharisa plc is listed on the Johannesburg Stock Exchange (JSE: THA) and the London Stock Exchange (LSE: THS, Equity Shares (Transition) Category).
