KAZ Minerals is responsible for the restoration and rehabilitation of land following the closure of its mining sites.
The Group is committed to rehabilitating mining sites after closure, as it is required by law in Kazakhstan and Kyrgyzstan. The operations’ General Directors are responsible for the Group’s 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. Provision is made to cover the costs of closure and rehabilitation and amounted to $59 million at 31 December 2018. More information can be found in note 26 to the financial statements on page 149 of the Annual Report 2018. The provision represents the discounted values of the estimated costs to decommission and reclaim the mines based on the current estimated life of mine of each deposit.
In December 2016, mining operations at Yubileyno-Snegirikhinsky ceased as mineral resources at the mine were fully exploited. A closure plan is currently being executed by the Group, which includes the sealing of all mine access points, the contouring of waste heaps, removal of buildings and infrastructure, and management of water run-off. The site will be returned as closely as possible to its pre-development state as required by legislation. No significant adverse impacts on the local environment are anticipated following completion of the required reclamation work.
