CONTENTS FINANCIAL STATEMENTS YEAR IN REVIEW DIRECTORS’ REPORT CORPORATE DIRECTORY SHAREHOLDER INFORMATION 8.

This expenditure includes all capitalised exploration and evaluation expenditure in respect of the area of interest, direct costs of construction, overheads and where applicable borrowing costs capitalised during construction. Once mining of the area can commence, the aggregated capitalised costs are classified under non-current assets as an appropriate class of property, plant and equipment. Accumulated mine development costs are depreciated on a units of production (UOP) basis over the economically recoverable reserves of the mine.
