Toronto, May 5, 2011 - Scorpio Mining Corporation (TSX:SPM) ("Scorpio Mining" or the "Corporation") announces that it has executed payment of CDN $20 million to retire fully all issued and outstanding 7% unsecured subordinated convertible debentures of the Corporation (the "Debentures"), which matured on May 5, 2011. The payments were made using funds generated by the Corporation from its Nuestra Señora operation in Sinaloa State, Mexico. By repaying the Debentures the Corporation is now completely debt free.

Parviz Farsangi, President and CEO, states: "It is the solid performance of the Nuestra Señora operation in the last two consecutive quarters that has allowed the Corporation to eliminate its debt. We are confident we will meet our 2011 commitments as previously stated, and continue to grow through development of our many existing assets. We believe the Corporation stands among the best performing silver producers with significant base metal by-product credits in Mexico."

ON BEHALF OF SCORPIO MINING CORPORATION
