FOURTH QUARTER 2011 HIGHLIGHTS
Financial

• Revenue from metal payable decreased 12% to $ 13.8 million in Q4 2011 compared to $15.7 million in Q4 2010. Although there was increased production of contained metals in Q4 2011 compared to Q4 2010, the decrease in revenue was due mainly to lower silver and copper payables due to variations in metallurgy, and commercial settlement variations which have subsequently returned to acceptable ranges; decreases in the recorded metal prices and an increase in lead concentrate inventory at the end of Q4 2011;
• Cash cost (recovery) per silver payable ounce, net of by-product credits, was $9.65 in Q4 2011 compared to $(1.82) in Q4 2010. This increase in Q4 2011 resulted from lower than usual payable silver as explained above; and the fact that not all of the contained metals from production were realized since a customer was not able to purchase all of the December production of lead concentrate, which contains a significant portion of silver. In addition, the Corporation incurred approximately $0.9 million of additional costs in Q4 2011 beyond those incurred in Q4 2010, specifically relating to additional spare parts for the mill, increased insurance premiums for increased coverage, year-end adjustments for labour, and contracting a third party to perform drilling. This increased cost accounted for $3.66 cash cost per silver payable ounce;
• Mine operating earnings in Q4 2011 decreased 34% to $3.6 million compared to $5.5 million in Q4 2010. The decrease in mine operating earnings is due to the factors explained above, namely decreases in metal payables and metal prices, an increase in concentrate inventory which led to reduced revenues; and the additional $0.9 million costs;
• Net loss in Q4 2011 was $(1.0) million or $0.00 per share (basic) compared to net earnings of $15.0 million or $0.08 per share (basic) in Q4 2010 as a result of the reduction in revenues and increased costs described above; the Q4 2010 earnings included a $11.5 million deferred income tax recovery adjustment which accounted for $0.06 per share (basic);
• Adjusted EBITDA⁽²⁾ in Q4 2011 decreased 52% to $3.6 million compared to $7.4 million in Q4 2010 as a result of the reduction in revenues, and additional costs described above; and
• Cash flow from operating activities in Q4 2011 decreased by 83% to $1.1 million compared to $6.6 million in Q4 2010 as a result of the reduction in revenues, additional costs described above and the prepayment of $1.8 million for reagents to be delivered in 2012.

Operations

• Underground ore production and plant throughput in Q4 2011 increased 32% and 17%, respectively, compared to Q4 2010;
• Recovered silver equivalent ounces⁽³⁾ in Q4 2011 increased 13% to 694,538 ounces compared to 612,941 ounces in Q4 2010;
• Contained metals produced in concentrates in Q4 2011 reflect an increase of 17%, 19% and 26% for silver, zinc and lead, respectively, and a decrease of 17% for copper compared to Q4 2010;
• Announced high-grade results from San Rafael drilling (Press release November 7, 2011); and
• Appointed Vice-President of Exploration.

⁽¹⁾ The year ended December 31, 2010 results include a $20.2 million gain on dilution and deconsolidation of Scorpio Gold Corporation and a $9.9 million future income tax recovery adjustment; the Q4 2010 results include an $11.5 million future income tax recovery adjustment.

NUESTRA SENORA MINERAL RESOURCES AND RESERVES UPDATE

The Corporation has identified an unexpected divergence between the mineral resource and reserve estimates set out in the technical report dated March 28, 2011 and entitled Mineral Reserve Update, Nuestra Señora, NI 43-101 Technical Report (the "Nuestra Señora Technical Report") prepared for the Corporation by Genivar Inc., and the actual mineralization that the Corporation has encountered in the main production areas between Levels 8 and 12 at the Nuestra Señora Mine. The Corporation has encountered ore with lower than estimated lead and copper grades in these production areas, and development and definition drilling has identified lower tonnages relative to what was expected in the Nuestra Señora Technical Report.

In order to better understand this divergence, the Corporation has commissioned a comprehensive update of the Nuestra Señora mineral resource and reserve estimates. As part of this update, in Q3 2011 the Corporation engaged Mine Development Associates, an independent expert, to prepare new resource and reserve estimates that are compliant with NI 43-101 and that take into account the latest information available to the Corporation. The Corporation expects the new resource estimate to be available by the end of Q2 2012. An updated reserve estimate is expected in late Q3 2012 or early Q4 2012.

As of the date of this press release, the Corporation's current assessment of the geology, exploration and production data indicates that the mineral deposit at Nuestra Señora is not as continuous as previously interpreted. The model developed by the Corporation based on the geological information and data available to it at the time, predicted areas suitable for block mining from large stopes. However, geological information and data from actual mining received by the Corporation since the development of such model suggests that the mineral deposit is more variable in distribution and continuity, and more confined in extent than anticipated. Accordingly, management expects a significant reduction in the resource and reserve estimates at the Nuestra Señora Mine. The magnitude of the reduction cannot be accurately quantified at this time. Such a reduction could adversely impact production, life of mine, and cash flow forecast, including the Corporation's previously released production guidance for 2012. A reduction in operating earnings from this mine could negatively impact earnings and the financial condition of the Corporation.

OUTLOOK FOR 2012

• Continuous improvement of safety and environmental systems building on the recent achievement of 1 million hours with no lost time accidents;
• Sustaining capital expenditures of $5.2 million allocated for maintaining and improving existing operations at Nuestra Señora;
• Approved $5 million for Phase I of the Nuestra Señora plant expansion by 80% to 2,750 tonnes per day. Phase I of this expansion which includes engineering, civil works, and the purchasing of long lead time items such as an additional used ball mill and the installation of a flash flotation cell, is expected to be concluded in Q2 2012. The commencement and completion of Phase II which includes construction and commissioning will depend on the results of the updated NI 43-101 resource and reserve estimates at Nuestra Señora, El Cajón and San Rafael, drilling results at La Verde and permitting. The total plant expansion is estimated at $20 million and will be funded internally;
• $9.3 million allocated for exploration including exploration drilling at Nuestra Señora and its adjacent deposits; infill and exploration drilling at San Rafael, El Cajón and La Verde to support near-term production growth; exploration drilling of multiple prospects in the Cosalá North District; and drill testing of the La Revancha and Tepozán projects in the Parral area;
  - Updated resource estimates at San Rafael and El Cajón deposits are expected by the end of Q2 2012 and reserve estimates are expected by the end of Q3 2012 or early Q4 2012;
  - Drilling on the La Verde Mine is expected to finish in Q2 2012 to be followed by geological modelling and interpretation. The Corporation will make an assessment at that time to determine whether the data will support a resource estimate. The mine is currently undergoing refurbishment to improve safety and production efficiency; and
  - 4,500 meters surface drilling program at La Revancha and Tepozán. The initial drill results from La Revancha in Parral District have returned significant silver values over substantial widths (Press release March 5, 2012).

The Nuestra Señora processing plant has an existing capacity of approximately 1,500 tonnes per day (tpd) but is expandable up to approximately 4,000 tpd. The Corporation has commenced Phase I of the plant expansion to 2,750 tpd. The commencement of Phase II of this expansion depends on the results of the resource and reserve update at Nuestra Señora and geological interpretation of the La Verde Mine to ascertain their ability to provide immediate expanded ore feed while the San Rafael and El Cajón deposits are being developed. Other growth alternatives being evaluated include the development of a second processing facility in the Cosalá District. Such expansion would allow for the diversification of process circuits and reduce the distances between multiple ore sources and processing facilities. Near term and future production growth to support these expansion scenarios are expected to come through advancement of deposits in the Cosalá District.
