Description of evidence supporting recognition of deferred tax asset when utilisation is dependent on future taxable profits in excess of profits from reversal of taxable temporary differences and entity has suffered loss in jurisdiction to which deferred tax asset relates During the year, management considered whether the unrecognised deferred tax asset related to the group's Papua New Guinea entity, Morobe Consolidated Goldfields Limited (MCG), should be recognised, partially or in full. Due to the significant increase in the Hidden Valley operation's estimated future taxable profits a portion of the unrecognised deferred tax asset to the value of R1.1 billion has now been recognised as at 30 June 2026. Management also considered the recognition of previously unrecognised deferred tax assets related to Harmony Gold Australia. Due to the acquisition of MAC Copper, which included the CSA mine, the group's Australian entities moved into a net deferred tax liability including the previously unrecognised deferred tax asset. Consequently, the full unrecognised deferred tax asset of R1.5 billion has now been recognised as at 30 June 2026.
