KAZ Minerals is responsible for the restoration and rehabilitation of land following the closure of its mining sites.
The Group is committed to rehabilitating mine sites after closure, as is required by law in the countries we operate in. The General Directors of the Group’s operations are responsible for compliance with closure and rehabilitation obligations. The Group periodically reviews and updates closure plans for each of its sites, including calculating the likely costs associated with closure.
The provision represents the discounted value of the estimated costs to decommission and reclaim the mines based on the current estimated life of mine of each deposit. During 2021, the Group began capping works at the Nikolayevsky above-ground tailings storage facility, as part of a retirement programme after deposition of tailings material was ceased in 2020.
