~ Large decrease due to reduced mining at Mogalakwena. Surface stockpiles were processed in 2009. Rock broken at Bokoni only
   included until 30 June 2009.
* Water reassigned to groundwater rainfall according to latest water model definitions.
† Increase attributed primarily to better internal measurements of the overall water balance.
Δ Parameter not reported as final figures for 2008 could not be verified.
° Excludes toll refining from Anglo Platinum marketing.
• Substandard acts and conditions reported in 2010.
‡ Reduction is due to exclusion of BRPM and Bokoni JVs.
