[1] Additions of US$0.9 million were recorded in trade payables as of June 30, 2026.
[2] The cost basis and the balance of accumulated depreciation and impairment include assets that are fully depreciated but remain in service. As of June 30, 2026, the initial cost of the fully depreciated assets that remain in service was US$0.7 million.
[3] The impairment charge relates to the change in the rehabilitation asset (see Note 20) for both Mazowe Mining Company (MMC) and Redwing Mining Company (RMC). The carrying amount was immediately impaired due to the non-operational status of these mines.
