PROVISION FOR ENVIRONMENTAL REHABILITATION PROVISION FOR ENVIRONMENTAL REHABILITATION
SIGNIFICANT ACCOUNTING ASSUMPTIONS AND ESTIMATES
Estimates of future environmental rehabilitation costs are determined with the assistance of an independent expert and are
based on the Group’s environmental management plans which are developed in accordance with regulatory requirements as
well as the life-of-mine plan (as discussed in note 9 to the consolidated financial statements) which influences the estimated
timing of the rehabilitation cash outflows and the planned method of rehabilitation of reclamation sites and deposition facilities.
An average discount rate ranging between 9.5% and 9.9% (2024: between 10.1% and 10.6%), average inflation rate of 5.1%
(2024: 5.6%) and the discount periods as per the expected life-of-mine were used in the calculation of the estimated net present
value of the rehabilitation liability.
ACCOUNTING POLICIES
The net present value of the estimated rehabilitation cost as at reporting date is provided for in full. These estimates are
reviewed annually and are discounted using a pre-tax risk-free rate that is adjusted to reflect the current market assessments of
the time value of money and the risks specific to the obligation.
Annual changes in the provision consist of financing expenses relating to the change in the present value of the provision and
inflationary increases in the provision, as well as changes in estimates.
The present value of dismantling and removing the asset created (decommissioning liabilities) are capitalised to PPE against an
increase in the rehabilitation provision. If a decrease in the liability exceeds the carrying amount of the asset, the excess is
recognised in profit or loss. If the asset value is increased and there is an indication that the revised carrying value is not
recoverable, an impairment test is performed in accordance with the accounting policy dealing with impairments of property,
plant and equipment. Over time, the liability is increased to reflect an interest element, and the capitalised cost is depreciated
over the life of the related asset. Cash costs incurred to rehabilitate these disturbances are charged to the provision and are
presented as investing activities in the statement of cash flows.
The present value of environmental rehabilitation costs relating to the production of inventories and sites without related assets
(restoration liabilities) as well as changes therein are expensed as incurred and presented as operating costs. Cash costs
incurred to rehabilitate these disturbances are presented as operating activities in the statement of cash flows. The cost of
ongoing rehabilitation is recognised in profit or loss as incurred.

These costs do not represent a reduction of the above liability and are expensed as operating costs.
(a)Change in estimate of environmental rehabilitation recognised in profit or loss
The decrease is mainly as a result of Crown Complex being classified as Mineral Reserve and now included in the Life of Mine,
resulting in a change in its rehabilitation methodology, from in situ to red earth footprint rehabilitation.
(b)Change in estimate of environmental rehabilitation recognised to decommissioning asset
Increases mainly as a result of inflationary increases in rehabilitation costs and the expansion of FWGR infrastructure.
(c)Environmental rehabilitation payments
40ha of the Brakpan TSF (2024: 25ha) and 4.4ha of the Driefontein 4 TSF (2024: 15.1ha) were vegetated during the year.
GROSS COST TO REHABILITATE
The Group estimates that, based on current environmental and regulatory requirements, the total undiscounted rehabilitation cost
is approximately R930.2 million (2024: R972.0 million).
