• Underground ore production and plant throughput in Q3 2011 increased 45% and 19% respectively compared to Q3 2010.
• Contained metals produced in concentrates in Q3 2011 reflect an increase of 22%, 11% and 17% for silver, zinc and copper respectively, and a decrease of 20% for lead compared to Q3 2010.
• Recovered silver equivalent ounces⁽³⁾ for Q3 2011 increased 13% to 604,975 ounces compared to 537,698 ounces in Q3 2010.
• As of September 30, 2011, the Corporation had $30.2 million in cash compared to $16.8 million as of June 30, 2011.
• As of June 15, 2011 the Corporation no longer maintained significant influence over the operations of Scorpio Gold Corporation ("Scorpio Gold"). The Corporation elected to record its investment in Scorpio Gold as an available-for-sale financial instrument measured at fair value with changes in fair value being recognized in other comprehensive income. Included in other comprehensive income for the three-month period ended September 30, 2011 is an unrealized gain on these shares of $3.5 million. As of September 30, 2011, Scorpio Mining still holds approximately 15.5 million shares in Scorpio Gold representing 13.7% of Scorpio Gold's issued and outstanding shares.

⁽¹⁾ Includes a $19.8 million gain on dilution and deconsolidation of Scorpio Gold Corporation for the nine-months ended September 30, 2010.
⁽²⁾ This is a non-IFRS performance measure; please see Non-IFRS Performance Measures section in the Corporation's Management Discussion and Analysis.
⁽³⁾ Silver equivalent ounces in 2011 were established using budgeted prices as follows: silver US$24 per oz.; zinc US$1.01 per lb.; lead US$1.02 per lb.; and copper US$3.58 per lb.

During Q3 2011, the operation was able to maintain a high processing rate with the introduction of profitable lower grade ore from contingent sources despite problems with mobile mining equipment which disrupted production from higher-grade mining areas.

Delivery was taken of a new jumbo drill, which was commissioned at the end of the quarter and is accelerating the advance of development for production and exploration purposes. The Corporation has made a further $4.5M purchase of new mining equipment that will replace aging machines as delivery occurs in Q1 and Q2 of 2012. As a contingency, the Corporation has engaged a contractor in the key area of production drilling to ensure that adequate long hole stoping tonnes are available in the near term. This contractor is expected to mobilize to site in early November 2011.

Review of Resources at Nuestra Señora

The Corporation has recognized an unexpected divergence between the Nuestra Señora mineral reserve estimate set out in the independent technical report (the "Technical Report") dated March 28, 2011 and entitled Mineral Reserve Update, Nuestra Señora, 43-101 Technical Report prepared for Scorpio Mining 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. While the Corporation has encountered lower than estimated lead and copper grades in these production areas, development and definition drilling has resulted in a shortfall of tonnes in some of the mineralized zones in these areas, compared to the reserve estimate in the Technical Report. In order to better understand this discrepancy, the Corporation has initiated a comprehensive review of the Nuestra Señora mineral reserve and resource estimates set out in the Technical Report. As part of this review, the Corporation has engaged an independent expert to review and produce a new resource and reserve estimate that is compliant with NI 43-101, and that takes into account, among other things, the Corporation's most recent available results and data. The Corporation expects the new resource and reserve estimate to be available by the end of the Q2 2012. Based on current information from production at the Nuestra Señora Mine, the Corporation expects that the new estimate will show a reduction of the Corporation's resources and reserves at Nuestra Señora, the amount of which cannot be accurately quantified at this time.

Other Developments and Exploration

Development at Candelaria continued on three levels with 8,500 tonnes of high-grade ore excavated in Q3 2011 grading 202 g/t silver, 2.89% zinc, 1.38% lead and 0.67% copper. In the coming quarter, open stope mining will be tested at Candelaria to assess the impact of dilution that results from that bulk mining method.

The Corporation is aggressively advancing its exploration activities to further build its mineral resource base and prove additional reserves. In the Cosalá District, the Corporation has NI 43-101 compliant mineral resources at the San Rafael and El Cajón deposits (see independent technical report prepared by Mine Development Associates and filed on SEDAR December 4, 2009), and over 40 exploration targets at various stages of advance. An 8,000 m delineation drilling program is currently underway with the objective of adding to and upgrading mineral resources at the San Rafael Deposit and recently operating La Verde Mine, to support near-term production growth.

There are currently six diamond drilling rigs operating on multiple projects, including step-out exploration drilling at the Nuestra Señora, Candelaria and La Verde deposits in the Cosalá District, and exploration drilling at the La Revancha and Tepozan deposits in the Parral District, Chihuahua. The potential for expanding known mineralization and discovering new zones of high-grade mineralization is high, and continued exploration success in these areas could potentially result in significant increases to the mineral resource base and overall mine life.
