Highlights
— Contracted M3 Engineering to complete the Pitarrilla feasibility study.
M3 has designed and built many mines in
Mexico , including the Penasquitomine.
— Feasibility study on track for mid-year 2012 completion.
— Construction permit application on track for second-half 2012
submission.
— Feasibility design is being based on an open-pit mine and a 16,000 tonne
per day plant with an agitated leach circuit producing a silver dore and
a flotation circuit producing separate zinc and lead concentrates
containing payable silver.
— Hired experienced project manager and key development and construction
management personnel.
— Measured and Indicated mineral resources estimate of 655.7 million
ounces of contained silver (at a 30 g/t silver cut-off grade).
— Inferred mineral resources estimate of 65.0 million ounces of contained
silver (at a 30 g/t silver cut-off grade).
“Pitarrilla’s mineral resources are significant and drive the potential for a long-life mine with strong annual silver production,” said
The Pitarrilla feasibility study is being prepared by
A diamond drill program of approximately 8,300 meters is scheduled for 2012, with the objective of expanding the near-surface oxide mineralization at the

Notes to Table 1:
1. Dr.
Warwick Board , Ph.D. (Geology),P.Geo ., is the Qualified Person forthe reported mineral resources estimate.
2. All mineral resources have been classified in accordance with current
CIM definition standards.
3. The Ordinary Kriging with appropriate top-cuts modeling methodology was
employed for the mineral resources estimates presented in the above
table.
4. Although a silver cut-off grade of 30 g/t Ag is considered at this time
to be the most likely economic cut-off grade for large-scale open-pit
mining of the Pitarrilla deposit, it has not yet been confirmed by the
appropriate mining studies. A detailed economic cut-off grade analysis
will be conducted as part of the Pitarrilla feasibility study.
5. Silver capping grades used in the estimation range between 415 g/t Ag
and 1,825 g/t Ag for the various oxide domains, and between uncapped to
1,370 g/t Ag for the various sulphide domains. Zinc capping grades used
in the estimation range between 0.55% Zn and 4.63% Zn for the various
oxide domains, and between uncapped and 10.00% Zn for the various
sulphide domains. Lead capping grades used in the estimation range
between uncapped and 4.02% Pb for the various oxide domains, and
between uncapped and 6.04% Pb for the various sulphide domains.
6. Detailed bulk density modeling was conducted taking into account
lithological variability (including an analysis of voids),
mineralization, and degree of oxidation.
7. The drillhole database including collar, survey, assay, lithology, and
mineralization, used in the preparation of the mineral resources
estimate in Table 1 was validated through conducting detailed
verification checks, including QA/QC of location and assay data.
8. Sums may not equal reported totals due to rounding.
