Represents adjustment for ore inventory movements and removal of production stripping costs
Adjusted operating costs represents net cash costs adjusted for finished goods inventory movements, divided by ounces sold
Represents spend on major projects that are designed to increase the net present value of the mine are not related to current production. Significant projects in the period include projects to facilitate
mining of Kapit ore-body, throughput and recovery related projects at Lihir.
Depreciation and amortisation of mine site assets is determined on the basis of the lesser of the asset's useful economic life and the life of the mine. Life-of-mine assets are depreciated
according to units of production and the remainder on a straight line basis. Depreciation and amortisation does not form part of All-In Sustaining Cost or All-in Cost with the exception of
amortisation on reclamation and remediation (rehabilitation) assets.
