• Production from the Nuestra Señora Mine in Q2 encountered lower silver, copper and lead grades compared to Q1 2013; however, the on-going placement of backfill, where higher-grading secondary stopes could readily be developed, will allow for safely mining of higher ore grades during H2 2013.
• Reduced plant throughput in Q2 primarily resulted from the scheduled relining of the two plant ball mills and accumulated downtime of one of these mills, which required replacement of a worn pinion and subsequent modification and corrective maintenance to overcome an elevated vibration issue.
• Reduced metal recoveries in Q2 were a consequence of the lower silver, copper and lead feed grades to the plant, coupled with the repeated stoppages for making mechanical adjustments on the repaired ball mill.

Other Developments:

• During Q2, the Company released the latest reserve estimate for the Nuestra Señora Mine and the Preliminary Economic Assessment ("PEA") for the advanced Cosalá District mineral resources. On the PEA, President and CEO, Pierre Lacombe, comments, "The PEA case outlines positive economics for the set of assumptions used. The PEA provides a base from which further optimization studies will be performed, regarding alternate development scenarios seeking to maximize net present value."
• During Q2, the Company received approval from the federal environmental authority (SEMARNAT) for its Environmental Impact Statement (MIA) pertaining to underground mining at the El Cajón and San Rafael deposits. The Company continues to work with the state offices of SEMARNAT to obtain the Change of Land Use Permit (CUS) related to El Cajón, which is also required prior to project commencement. After receiving a denial of the original application in May, the Company has been in liaison with the authorities and is advancing a revised submittal that is anticipated to be filed in early Q3. Receipt of the CUS may accordingly be expected in Q4, and once in hand, the Company is ready to break ground and advance the development work required to put the El Cajón deposit into production in Q1 of 2014.
• Sales negotiations for the concentrates produced at the Nuestra Señora plant were completed late in Q2, with delivery to the account of the retained buyers initiated as of July 1, 2013.
• A contract mining arrangement has been finalized that will allow for provision of silver-copper ore from the Company's wholly-owned La Verde Mine to the Nuestra Señora plant. La Verde entered production in the mid-1980's and was operated continuously until Scorpio assumed control of the operation in early 2011, to perform refurbishment for improved safety, exploration drilling and metallurgical testing. By Q4 2013, La Verde may contribute up to 15,000 tonnes per month of relatively high-grade, silver-copper material (per historical records; no NI 43-101 compliant resource estimate is available for this deposit) from a series of parallel, near-vertical mineralized shear zones. The first ore stream is expected to be made available by the end of Q3.
