Notes:

    1. Mineral Reserves and Mineral Resources are as defined by CIM Definition Standards on Mineral Resources and Mineral Reserves
    2. Mineral Resources are exclusive of Mineral Reserves
    3. Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability
    4. There are no known legal, political, environmental or other risks that could materially affect the potential development of the Mineral Resources or Mineral Reserves at Caylloma or San Jose
    5. Mineral Resources and Mineral Reserves are estimated as of July 4, 2013 for San Jose and as of June 30, 2013 for Caylloma and are reported as of December 31, 2013 taking into account production-related depletion for the period through December 31, 2013
    6. Mineral Reserves for San Jose are estimated using break-even cut-off grades based on assumed metal prices of US$24.00/oz Ag and US$1,400.00/oz Au; estimated metallurgical recovery rates of 89% for Ag and 89% for Au and projected operating costs for year-end 2013. Mineral Resources are estimated at a Ag Eq cut-off grade of 70 g/t, with Ag Eq in g/t = Ag (g/t) + Au (g/t) * ((US$1,391.63/US$25.14) * (89/89))
    7. Mineral Reserves for Caylloma are estimated using break-even cut-off grades based on estimated NSR values using assumed metal prices of US$24.00/oz Ag, US$1,400/oz Au, US$2,100/t Pb and US$1,900/t Zn; metallurgical recovery rates of 82% for Ag, 45% for Au, 93% for Pb and 88% for Zn; and projected operating costs for year-end 2013. Caylloma Mineral Resources are reported based on estimated NSR values using assumed metal prices of US$25.14/oz Ag, US$1,391.63/oz Au, US$2,116/t Pb and US$2,028/t Zn; metallurgical recovery rates as detailed for Mineral Reserves; and an NSR cut-off grade of US$50/t
    8. Totals may not add due to rounding
    9. N/A = Not Applicable
