| Schedule of Sensitivity Analysis for Types of Market Risk | The group has reviewed its foreign currency exposure on financial assets and financial liabilities and has identified the following sensitivities in the exchange rates that would affect profit and loss before tax: •Rand/US$ exchange rate – 3% (2025: 4%) based on the standard deviation from a one-year forecast of various financial institution outlooks •Rand/A$ exchange rate – 5% (2025: 3%) based on the standard deviation from a one-year forecast of various financial institution outlooks •A$/US$ exchange rate – 5% (2025: 4%) based on the standard deviation from a one-year forecast of various financial institution outlooks. Only material foreign currency exposure balances were considered when determining the need for a sensitivity analysis and therefore management has not performed a sensitivity analysis on PGK/US$ exchange rates.

prices that would affect other comprehensive income and profit or loss before tax, respectively: •Gold price: 11% (2025: 11%) based on the standard deviation of a one-year forecast gold price from various financial institution outlooks •Silver price: 17% (2025: n/a) based on the standard deviation of a one-year forecast silver price from various financial institution outlooks. A sensitivity has been performed in the 2026 year due to the increased silver derivatives balance and the silver price volatility.

| Schedule of Financial Assets Measured at Fair Value | The following table sets out the group’s assets and liabilities measured at fair value by level within the fair value hierarchy:
(a)The level 1 valued assets comprise of listed equity securities held by MAC Copper and are designated at fair value through other comprehensive income. The level 3 valued instruments comprise mainly of the equity investment in Rand Mutual Assurance. The fair value of the investment was estimated with reference to an independent valuation. A combination of the "Embedded Valuation" and "Net Asset Value" techniques were applied to revalue the investment at the reporting dates. In evaluating the group's share of the business, common practice marketability and minority discounts as well as additional specific risk discounts were applied. There are no inputs to the valuation that a reasonably possible change would result in a material change in the fair value of the investment. (b)The level 1 valued assets comprise of listed equity securities designated as fair value through other comprehensive income instruments. The majority of the level 2 valued assets are directly derived from the Top 40 index on the JSE and are discounted at market interest rates. This relates to equity-linked deposits in the group's environmental rehabilitation trust funds. The remaining balance of the environmental trust funds is carried at amortised cost and therefore not disclosed here. (c)The mark-to-market remeasurement of the derivative contracts (refer to note 17 for further details) was determined as follows: •Foreign exchange contracts comprise of zero cost collars: The zero cost collars were valued using a Black-Scholes valuation technique derived from spot Rand/US$ exchange rate inputs, implied volatilities on the Rand/US$ exchange rate, Rand/US$ inter-bank interest rates and discounted at a market interest rate (zero-coupon interest rate curve) •Rand gold forward sale contracts: spot Rand/US$ exchange rate, Rand and dollar interest rates (forward points), spot US$ gold price, differential between the US interest rate and gold lease interest rate which is discounted at a market interest rate •US$ gold forward sale contracts: spot US$ gold price, differential between the US interest rate and gold lease interest rate and discounted at a market interest rate •Silver contracts (zero cost collars): a Black-Scholes valuation technique, derived from the spot US$ silver price, strike price, implied volatilities, time to maturity and interest rates and discounted at a market interest rate •Rand gold zero cost collar contracts: a Black-Scholes valuation technique, derived from spot Rand/US$ exchange rate, spot US$ gold price, Rand and dollar interest rates (forward points) with discounting at the market interest rate (zero- coupon interest rate curve), US$ gold forward rates, time to maturity and implied volatilities 37Financial risk management continued Fair value determination for financial assets and liabilities continued (c)The mark-to-market remeasurement of the derivative contracts (refer to note 17 for further details) was determined as follows: continued •US$ gold zero cost collar contracts: a Black-Scholes valuation technique, derived from spot US$ gold price, US$ gold forward rates, US$ interest rates with discounting at the market interest rate (zero-coupon interest rate curve), time to maturity and implied volatilities. (d)The fair value of receivables arising from copper and silver concentrate sales contracts at 30 June 2026 which contain provisional pricing mechanisms are determined using the appropriate quoted forward price from the exchange that is the principal active market for the particular metal. As such, these receivables, which have the characteristics of a commodity derivative, are classified within Level 2 of the fair value hierarchy. (e)At 30 June 2026, the fair value movement was calculated using a discounted cash flow model, taking into account forecast dividend payments over the estimated repayment period of the loan at a rate of 11.2% (2025: 11.5%). A 22 basis points (2025: 28 basis points) change in the discount rate, which would represent a reasonably possible change based on expected movement in lending rates, would not cause a material change in the fair value of the loan. The loan balance forms part of other non-current assets in the balance sheet. During the 2026 year, repayments to the value of R23 million (2025: R28 million) were received. (f)Contingent consideration liabilities (refer to note 27) consist of the following: •Mponeng operation The contingent consideration related to the Mponeng operation was determined using the expected gold production profile for Mponeng. At 30 June 2026, the liability was valued at R433 million (2025: R676 million), using a discounted cash flow valuation method at a post-tax real rate of 11.1% (2025: 10.8%). Should the expected gold production profile increase by 10.8% or decrease by 10.8%, the contingent consideration liability would increase by R157 million (2025: R319 million at 11.5%) or decrease by R157 million (2025: R319 million at 11.5%) respectively. This represents reasonably expected changes which were determined based on the average variance between the planned production and the actual production achieved over a number of years. No other reasonably expected changes in key unobservable inputs would have caused a material change in the fair value of the liability. •Eva Copper The contingent consideration for Eva Copper includes contingent consideration valued at R540 million (2025: R781 million), using a probability weighted method for the new resource payment and a discounted cash flow valuation for the excess payment, both discounted at a post-tax nominal rate of 11.1% (2025: 11.4%). A long-term copper price of US$4.78/lbs (2025: US$4.25/lbs) was applied in the valuation. A 11.3% change (2025: 11.8%) in the long-term copper price, which would represent a reasonably possible change based on the standard deviation of market analysts long-term forecasts of the copper price, would not cause a material change in the fair value of the contingent consideration. •NSR Royalty The NSR royalty was valued at R1.1 billion, using a discounted cash flow valuation, discounted at a post-tax real discount rate of 7.0%. The valuation is determined using the present value of the expected discounted cash flows over the expected life-of-mine of CSA. Expected cash flows are determined by making use of market analyst forecasts of the copper price and after deducting for the estimated treatment and refining charges in terms of the existing offtake agreement with Glencore. Should the long-term copper price either increase or decrease by 11.3%, which would represent a reasonably possible change based on the standard deviation of market analysts long-term forecasts of the copper price, the fair value of the royalty liability would increase or decrease by R131 million respectively. (g)The streaming contract liabilities balance includes a copper compound and silver embedded derivative valued at R147 million and R525 million, respectively. These liabilities were assumed by the group on acquisition of MAC Copper and are measured at fair value through profit or loss. Refer to note 29. •The copper compound derivative relates to the embedded copper price within the copper stream and the buy-down option. The copper compound derivative is valued using a copper future curve simulation valuation model and a Monte-Carlo valuation for the buy-down option at each reporting date. The following key assumptions were used in the valuation of the copper compound derivative: Copper spot price of US$13 279 per tonne, LME Copper implied volatility of 22.3% and own credit spread 8.4%. In isolation, at 30 June 2026, a 10% increase/decrease in copper spot price, which would represent a reasonably possible change based on the standard deviation of market analysts' short-term forecasts of the copper price, would not cause a material change in the fair value of the copper stream embedded derivative liability. •The silver derivative relates to the embedded silver price within the silver stream. The silver derivative is valued using a silver future curve simulation valuation model at each reporting date. The following key assumptions were used in the valuation of the silver derivative: Silver spot price of US$58.26/oz and own credit spread of 7.7%. In isolation, at 30 June 2026, a 20% increase/decrease in silver spot price, which would represent a reasonably possible change based on the standard deviation of market analysts' short-term forecasts of the silver price, would not cause a material change in the fair value of the silver derivative liability.
