Notes for Mineral Reserve and Mineral Resource Estimates:
  1. CIM Definitions and Standards were followed for Mineral Reserve and Mineral Resource Estimates.
  2. Mineral Reserves are estimated at a NSR cut-off value of US$40/tonne at Nuestra Se�ora, US$54/tonne at San Rafael and US$190/tonne at Galena.� The NSR cut-off is calculated using recent operating results for recoveries, off-site concentrate costs, and on-site operating costs.
  3. Mineral Resources are estimated at a NSR cut-off value of US$34/tonne at San Rafael, US$40/tonne at Zone 120, US$30/tonne at El Caj�n and US$190/tonne at Galena.� Mineral Resources at Nuestra Se�ora are estimated at a 90g/tonne silver equivalent cut-off grade.� NSR and silver equivalent cut-offs were calculated using recent or expected operating results for recoveries, off-site concentrate costs, and on-site operating costs.
  4. Mineral Reserves are estimated using metal prices of US$16.00/oz Ag, $2.50/lb Cu, $0.90/lb Pb and $0.90/lb Zn.
  5. Mineral Resources are estimated using metal prices of US$18.00/oz Ag, $3.00/lb Cu, $1.05/lb Pb and $1.05/lb Zn.
  6. Mineral Resources are exclusive of Mineral Reserves and as such the Mineral Resources do not have demonstrated economic viability
  7. A minimum mining width of 4.5 feet was used for estimating Galena Reserves, with a minimum additional dilution of 0.5 feet from both the hangingwall and footwall.� A mining recovery of 95% was used to reflect the selective nature of the mining methods used at the operation.
  8. A mining recovery of 90% was used for estimating Mineral Reserves at Nuestra Se�ora and San Rafael to reflect the mining methods used at the operations.
  9. Numbers may not add or multiply accurately due to rounding.
  10. The Mineral Resource estimate for the Cosal� Operations is based on block models prepared by independent mineral resource consultants. The Nuestra Se�ora Mineral Reserve and Resource estimate was prepared by Company personnel under the supervision of James Stonehouse, a Qualified Person for the purpose of NI 43-101.� The San Rafael, Zone 120 and El Caj�n Mineral Resource estimates were prepared by� Paul Tietz, C.P.G.� who is all independent consultants and Qualified Persons for the purpose of NI 43-101.� The San Rafael Mineral Reserve estimate was prepared by company personnel under the supervision of Shawn Wilson, a Qualified Person for the purpose of NI 43-101.
  11. The Mineral Resource estimate for the Galena Complex was prepared using a combination of block modelling and the accumulation method.  The Mineral Resource estimate was prepared by Company personnel under the supervision of Aaron Gross, C.P.G., a Qualified Person for the purpose of NI 43-101.� The Mineral Reserve estimate was prepared by Company personnel under the supervision of Shawn Wilson, a Qualified Person for the purpose of NI 43-101.
