*Note: The Copper Rand mine closed in December 2008. The Proven reserves reported in the table were adjusted from the published mineral reserves at year-end 2007 by subtracting the total mined tonnes in 2008 (data sourced from Q3 MD&A 2008 and internal reports for Q4 2008). The ore mined in Q4 2008 was selectively high-grade and most likely brought down the remaining grade of the Proven category; accurate calculations of the copper grade of the remaining ore in the Proven category is not possible as no reconciliation was done at year-end 2008. Other categories remain unchanged. The data has been converted from short tons to tonnes (x 0.907) and from oz/short ton to g/t (x 34.28).
