20 | Provisions
Site restoration Site restoration relates to the estimated cost of closing down the mines and projects and represent the site and environmental restoration costs, estimated to be paid as a result of mining activities or previous mining activities. For the Blanket Mine site restoration costs are capitalised in property, plant and equipment with an increase in the provision at the net present value of the estimated future and inflated cost of site rehabilitation. Subsequently the capitalised cost is amortised over the life of the mine and the provision is unwound over the period to estimated restoration. For properties in the exploration and evaluation phase, such as the Bilboes, Maligreen and Motapa projects, site restoration costs are capitalised in exploration and evaluation assets with an increase in the provision at the undiscounted value of the estimated cost of site rehabilitation. Subsequently the costs capitalised are not amortised and the provision is not unwound.

* | The change in estimate is due the Blanket Mine’s LoM that was extended to 2041 (that is inclusive of inferred resources and it based on an internal estimate representing management’s best estimate of the LoM inclusive of the latest drilling results).
@ | After further review of the Motapa claims the old tailings storage facility, previously included in the rehabilitation liability, is not within the Caledonia claims area. The tailing storage facility was subsequently excluded from the rehabilitation liability footprint.
The discount rate in calculating the present value of the Blanket Mine provision is 4.19% (2023: 4.14%) and is based on a risk-free rate and cash flows are estimated at an average 2.14% inflation (2023: 2.40%). The gross rehabilitation costs, before discounting, amounted to $5,950 (2023: $5,629) for Blanket Mine as at September 30, 2024. The undiscounted gross rehabilitation costs for exploration and evaluation assets as at September 30, 2024, amounted to $4,466 (2023: $4,466) for Bilboes Holdings, $567 (2023: $1,466) for Motapa and $287 (2023: $287) for Maligreen.
