Provision is made for costs relating to environmental rehabilitation consisting of activities relating to restoration, decommissioning as well as costs of residual impact at a rehabilitated mine after final closure restoration and decommissioning have been completed. Estimates are based on unscheduled closure costs that are reviewed internally every six months and by external consultants every three years or earlier, should the level of risk require such external review. Where provision is made for dismantling of assets and site restoration costs, an asset of similar initial value is raised and depreciated in accordance with the accounting policy for property, plant and equipment.
Contributions are made to the environmental rehabilitation funds to provide for funding of costs relating to the residual impact at each mine after closure, rehabilitation and decommissioning have been completed. The environmental rehabilitation funds are consolidated.
