Tharisa advises stakeholders that it is currently managing a cybersecurity incident after detecting

About Tharisa
Tharisa is an integrated resource group critical to the energy transition and decarbonisation of
economies. 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. Tharisa plc is listed on the Johannesburg Stock Exchange (JSE: THA) and the
Main Board of the London Stock Exchange (LSE: THS).
