**Totals may not add due to rounding. Metal price assumption (in USD) used to calculate the $40 NSR COG for all Deposits are Cu=$2.50/lb Zn=$0.80/lb Pb=$0.85/lb and Ag=$20.00/oz. All mineral estimates exclusive of dilution and recovery factors. See Technical Reports filed under Capstone's profile on SEDAR for further information. 

*Grade corrected from December 31, 2011 AIF. No change to contained metal.
