Toronto, April 1, 2011 - Scorpio Mining Corporation (TSX: SPM) ("Scorpio" or the "Corporation") is pleased to announce its financial and operating results for the fourth quarter ("Q4") and the year ended December 31, 2010.

Performance Highlights:

Parviz Farsangi, President and Chief Executive Officer comments, "We are very pleased with our 2010 financial results, in particular with the fourth quarter which forms the basis for an improved 2011 forecast. In 2011, the Corporation aims to produce nearly 50% more silver equivalent ounces than in 2010 and also carry out an aggressive exploration program. We believe these results place the Corporation among the best performing silver producers with significant base metal by-product credits in Mexico. I thank our team for its focus and commitment and for setting the stage for our next level of success, including plant expansion."
