Estimates done at November 30, 2010 and reconciled to February 29, 2012 by including material removed by trial
mining and bulk sampling in Q4 FY2011 and FY2012.
* Saxendrift probable mineral reserves are exclusive from the indicated mineral resources.
Rockwell also holds the Zwemkuil Project (incl. Zwemkuil, Mooidraai and Holsloot properties), which was reviewed in fiscal 2011. This is a significant exploration target, but to date there has not been sufficient work done to estimate mineral resources.
Estimates completed by Rockwell's Group Mineral Resources Manager, GA Norton, (Pr. Sci. Nat.), a qualified person who is not independent of the Company. Reviewed by TR Marshall, PhD, (Pr. Sci. Nat.), an independent qualified person.
