Vancouver, February 23, 2010 - Scorpio Mining Corporation (TSX: SPM) is pleased to present an overview of its first year in commercial production and report that it has set another record for metal production in the fourth quarter ended December 31, 2009 ("Q4").

Peter J. Hawley, Chairman, CEO comments, "The fourth quarter mine production and mill throughput is another record quarterly performance for the Company since we declared commercial production at the Nuestra Señora mine in January 2009. The Company continues to ramp up operations for 2010 with the Q1 2010 mill throughput scheduled for 30,000 tonnes per month. It has been a great first year with the team, mine and mill facility out-performing all targets set for each quarter. As the Platte River Gold acquisition nears completion, the Company continues to look forward to increased production and a planned mill expansion for 2010."

Fourth Quarter 2009 Highlights:

• The Company's Mexican operations generated positive cash flows.
• Nuestra Señora cash operating costs were 27% lower than budgeted at US$35.47 per tonne compared with the budgeted cost of US$48.45 per tonne⁽¹⁾.
• Underground ore production increased from 39,687 tonnes in the third quarter 2009 ("Q3") to 54,860 tonnes in Q4, an increase of 38%.
• The average monthly mill throughput increased from 18,975 tonnes in Q3 to 23,793 tonnes in Q4, an increase of 25%. The Company expects mill throughput to further increase to a projected 30,000 tonnes per month for Q1 2010.
• During Q4, the mill processed 71,378 tonnes in 81 days of production at an average grade of 1.25% lead, 0.43% copper, 2.78% zinc and 99 g/t silver. This represents a 25% increase from Q3 production of 56,925 of tonnes in 77 days at an average grade of 1.30% lead, 0.44% copper, 2.47% zinc and 105 g/t silver.
• During Q4, contained metals produced in concentrates consisted of 1.371 million pounds of lead, a 24% increase from Q3; 485,000 pounds of copper, a 45% increase from Q3; 3.331 million pounds of zinc, a 57% increase from Q3 and 202,451 ounces of silver, a 21% increase from Q3. For comparison, in Q3 the contained metals produced were 1.108 million pounds of lead, 335,000 pounds of copper, 2.120 million pounds of zinc and 167,817 ounces of silver. The Company's mandate for Q4 was to focus on increasing mill throughput, and, as a result of higher metal prices, the Company was able to process lower-grade material in Q4 thereby reducing its reliance on the higher-grade cut and fill ore and extending the high-grade life of mine sectors.
• For the first year of commercial production, contained metals produced in concentrates consisted of 4.188 million pounds of lead, 1.186 million pounds of copper, 8.747 million pounds of zinc and 600,375 ounces of silver.

2009 Overview

• A total of 178,421 tonnes mined of which 141,640 tonnes were ore.
• The mill facility operated 271 days for the year and processed 210,324 tonnes of material.
• Average recovery for lead in lead concentrate payable was 74%; for copper in copper concentrate payable was 57%; for zinc in zinc concentrate payable was 78% and for silver in lead and copper concentrates payable was 88%.
• Lead concentrates graded on average 51.98% lead and 3,019 grams per tonne silver payable for the year.
• Copper concentrate graded on average 25.42% copper and 3,088 grams per tonne silver payable for the year.
• Zinc concentrate graded on average 56.41% zinc payable for the year.
