Notes:
  1. Mineral Reserves and Mineral Resources are as defined by the CIM Definition Standards on Mineral Resources and Mineral Reserves.
  2. Mineral Resources are exclusive of Mineral Reserves.
  3. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
  4. Caylloma Mineral Reserves are estimated and reported as of June 30, 2010 using break-even cut-off grades based on estimated NSR values using assumed metal prices of US$16.63/oz Ag, US$1066.68/oz Au, US$1984/t Pb and US$1962/t Zn; historic metallurgical recovery rates of 87% for Ag, 43% for Au, 91% for Pb and 89% for Zn; and historic operating costs adjusted for inflation. Caylloma Mineral Resources are reported as of June 30, 2010 based on estimated NSR values using the aforementioned assumed metal prices and a cut-off grade of US$30/t.
  5. Caylloma Mineral Resources include oxide material that is not amenable to processing in the existing flotation plant. Measured and Indicated oxide resources are estimated at 831,100 tonnes averaging 200 g/t Ag, 0.38 g/t Au, 1.10% Pb and 1.30% Zn. Inferred oxide resources are estimated at 677,000 tonnes averaging 176 g/t Ag, 0.30 g/t Au, 0.50% Pb and 0.91% Zn.
  6. San Jose Reserves are estimated and reported as of Dec. 31, 2010 using break-even cut-off grades based on assumed metal prices of US$15.12/oz Ag and US$897.51/oz Au, estimated metallurgical recovery rates of 88% for Ag and 90% for Au and projected operating costs. San Jose Resources are estimated and reported at a Ag Equivalent cut-off grade of 100 g/t, with Ag Eq in g/t = Ag (g/t) + Au (g/t) * ((US$856.16/US$13.75) * (91.5/92.5)) = Ag (g/t) + Au (g/t)*61.6.
  7. Totals may not add due to rounding procedures.
