1 Large decrease owing to reduced mining at Mogalakwena. Surface stockpiles were processed in 2009. Rock broken at Bokoni only included until 30 June 2009
2 Water reassigned to groundwater rainfall according to latest water model definitions.
3 Increase attributed primarily to better internal measurements of the overall water balance.
4 Reduction is owing to exclusion of BRPM and Bokoni JVs.
5 Not measured.
6 Parameter not reported as final figures for 2008 could not be verified.
7 Substandard acts and conditions reported in 2010.
8 Excludes toll refining from Anglo American Platinum Limited marketing.
