Title: Nuestra Senora Main Zone Increases In Size With Underground Drilling Reporting 988 g/t Ag, 11.06% Zn, 2.36% Cu, 8.63% Pb and 0.729 g/t Au Over 1.90 Meters And 6.70 Meters Grading 325 g/t Ag, 3.89% Zn, 2.03% Cu, 1.18% Pb and 0.343 g/t Au

Vancouver, March 12, 2008 - Scorpio Mining Corporation (TSX:SPM) is pleased to report additional underground drill results targeting the main zone of the Nuestra Senora deposit from the 11th, 10th, 9th, 8th and 6th Levels of the Nuestra Senora ramp at its 100% owned Nuestra Senora project, Sinaloa State, Mexico.

Peter J. Hawley, Chairman, CEO comments, "Drilling of the main zone of the Nuestra Senora deposit continues to support the overall wide spread mineralization modelled and is also allowing mineral resources to be converted to reserves. Given the recent surge in metal prices, the planned start of commissioning of the mill on March 31st, 2008 is well timed for the Company to benefit from the higher prices of the various commodities."
