* For comparative purposes the metal prices used to calculate silver equivalent ounces recovered are based upon the following: silver at US$24 per oz.; zinc at US$0.90 per lb.; copper at US$3.50 per lb. and lead at US$0.90 per lb.

• Record quarterly throughput of 136,610 tonnes was attained in Q3 2013 due to high processing plant availability of 97.6% in a period with limited planned maintenance requirements.
• Production from the Nuestra Señora Mine in Q3 2013 encountered higher zinc, lead and silver head grades compared to Q2 2013, while copper head grade was lower.
• Changes in quarter-on-quarter metal recoveries were in line with relative head grade changes.
• Despite a significant drop in copper grade and recovery, the quality of copper in concentrate was the highest on record. A record in the quality of the lead concentrate was also achieved.

Other Developments:

• At the end of Q3 2013, a 14% cut in the Company's workforce was implemented across operational and exploration departments. These changes were necessary to increase operational efficiency as well as providing a prudent response to global economic conditions which have caused significant declines in metal prices. Further structural changes will be implemented in Q4 2013 to facilitate ongoing improvement and personnel development.
• During Q3 2013, the federal environmental authority (SEMARNAT) requested additional information from the Company related to its Change of Land Use Permit (CUS) application, for allowing development of the El Cajón underground mine. That information was submitted at the end of Q3 2013 and liaison with SEMARNAT continues to advance this final, pending permit. Once in hand, the Company will immediately commence the development work required to put the El Cajón deposit into production. The related environmental impact statement had been accepted in April 2013.
• Contract mining has commenced at the Company's wholly-owned silver-copper La Verde Mine. During Q3 2013, La Verde provided a small quantity of ore which has been transported to the Nuestra Señora plant. Initial process optimization trials will commence during Q4 2013 and production should ramp soon after, approaching 15,000 tonnes per month by year-end. La Verde entered production in the mid-1980's and was operated continuously until Scorpio assumed control of the operation in early 2011, starting with improvements to ground control, followed by exploration drilling and metallurgical testing.
• During Q3 2013, JDS Energy and Mining Inc. was engaged to perform a prefeasibility study (PFS) for underground mining of the El Cajón deposit. A development decision for El Cajón has already been made on the strength of the existing NI 43-101 resources, its proximity to the Nuestra Señora processing plant, and results of the recent Preliminary Economic Assessment of the Cosalá District. However, the completion of the PFS, expected in Q1 2014, will result in the publication of NI 43-101-compliant mineral reserves.
