Disclosure of provisions [text block] | 25 Provisions Site restoration Site restoration relates to the estimated cost of closing down the mines and represents the site and environmental restoration costs, estimated to be paid throughout the period up until closure due to areas of environmental disturbance present at the reporting date as a result of mining activities. In the case of Blanket Mine the costs of site restoration are discounted based on the estimated life of mine. Site restoration costs at Blanket Mine are capitalised to mineral properties depreciated at initial recognition and amortised systematically over the estimated life of the mine for costs relating to the decommissioning of property, plant and equipment.
