* 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.

Head grade and recovery differences between Q3 2012 and Q3 2011 reflect changes in the blend of available ore sources from the Nuestra Señora mine at those times. The Nuestra Señora mine has multiple mineralized zones with varying metal grades and ratios. Metallurgical performance is largely dependent upon the blend of ore sources fed to the plant. In Q3 2012, the recovery of copper and silver was substantially reduced due to the low copper head grade.

The average head grades of copper and silver processed in July and August were 0.18% and 86 g/t, respectively, which were relatively low compared to past production. However, in September, mine production from areas with higher grades resulted in significantly higher head grades of 0.27% for copper and 96 g/t for silver. The Company's objective is to maintain similar higher head grades throughout Q4 2012.

Mine development during Q3 2012 focused on increasing drilled and blasted ore stocks to maintain an equivalent plant supply of 10 weeks. Since the beginning of Q3 2012, the Company implemented a number of cost reduction initiatives and strengthened its operations with the addition of a Chief Mine Geologist, Mine Maintenance Superintendent and a new Mine Manager.

At the end of Q3 2012, the Company commissioned a flash flotation cell in the process plant, which is currently under evaluation. The Company expects to improve the efficiency of the flash flotation cell throughout Q4 2012 as head grades to the plant are stabilized.

About Us

Scorpio Mining Corporation is a silver producer operating in Mexico with significant base metal by-product credits. In addition, the Company has over 40 exploration targets mostly in the vicinity of its current operations.

The 100% owned Nuestra Señora Mine and plant located in the Cosalá District of Sinaloa State, Mexico, has proven to be a low-cost operation with the benefit of flexible mining methods and diversified metal production. It has a fully mechanized underground operation and a processing facility built for expansion to 4,000 tonnes per day. The plant produces zinc, copper and lead concentrates with a significant silver component in the copper and lead concentrates. Scorpio Mining's strategy focuses on exploring and developing its existing mineral properties. At the nearby San Rafael and El Cajón deposits, an extensive diamond drilling program is in progress to potentially increase the mineral resource base and support an upgrade to reserve category.

Scorpio Mining also holds a 100% interest in the advanced, high-grade La Revancha silver and Tepozán silver-gold projects, both located in the productive Parral District within the respective states of Chihuahua and Durango, Mexico.

Scorpio Mining's Interim CEO, Peter J. Hawley, P.Geo., is a qualified person for the Nuestra Senora operations and has reviewed and approved the content of this release. For additional information, please see the Company's website at www.scorpiomining.com.
