| Schedule of estimates and assumptions used in calculation of impairment of goodwill | The Group’s estimates and assumptions used in the 31 December 2025 impairment testing include:
*No impairment assessment performed at 31 December 2024 and 2025 as carrying values reduced to nil due to change in the rehabilitation provision 1Includes the operating gold mines Driefontein, Kloof and Beatrix 2The Keliber impairment assessment at 31 December 2025 applied an average lithium hydroxide price of US$17,475/t (2024: US$18,640/t, 2023: US$22,933/t), nominal discount rate of 10.1% (2024: 9.9%, 2023: 10.1%), inflation rate of 2% (2024: 2%, 2023: 2%) and a life-of-mine of 20 years (2024: 23 years, 2023:24 years) 3The estimates and assumptions used in the impairment assessment of the Burnstone project include an average gold price of R1,670,512/kg (2024: R1,189,493/kg, 2023: R1,012,625/kg), inflation rate of 3.5% (2024: 5.0%, 2023: 6.0%) and life-of-mine of 23 years (2024: 25 years, 2023: 25 years) 4No impairment assessment was performed for Mimosa at 31 December 2025. The average PGM basket price used on the Mimosa equity-accounted joint venture at 31 December 2024 was R25,433/4Eoz (2023: R26,632/4Eoz) 5The average prices and the exchange rate were derived by considering various bank and commodity broker consensus forecasts 6Nominal discount rate for the Burnstone project is 15.2% (2024: 17.5%, 2023: 18.9%) and for the equity-accounted joint venture Mimosa at 31 December 2024 was 22.7% (2023: 31.2%) 7The nominal discount rate is calculated as the weighted average cost of capital of the respective CGUs 8The inflation rate is based on the expected forecast inflation rate in the geographical region which most affects the CGU's cash flows 9Periods longer than five years are considered appropriate based on the nature of the operations since a formally approved life-of-mine plan is used to determine cash flows over the life of each mine based on the available reserves
