INTANGIBLE ASSETS
Mineral properties
Mineral properties acquired are recognized at fair value at the acquisition date. Mineral properties are recognized at fair value if acquired as part of a business combination, whereas they are recognized at cost if acquired as an asset. Mineral properties are tested annually for impairment on the same basis that property, plant and equipment are when there is an indication of impairment. Mineral properties are amortized on units of production basis from the point at which the mine commences production (refer to ‘depreciation and amortization’ policy below).
