Scorpio Mining Provides Future Production Outlook

TSX:SPM

VANCOUVER, April 21 /CNW/ - Scorpio Mining Corporation ("Scorpio", or the "Company") (TSX: SPM), wishes to outline its planning and future outlook with respect to the Company's Mexico operations and intended production increases.

Peter J. Hawley, Chairman, CEO reports, "The Company is in the process of finalizing an expansion plan for its Mexico operations. Metallurgical work and flow sheet design completed by SGS Lakefield Research show that the San Rafael mineralization (Platte River project) reports a lead concentrate that grades 58% lead and 680 g/t silver with 78% recovery, and a zinc concentrate that grades 51% zinc and 128 g/t silver with 82% recovery. The current plan is to install a second circuit for the San Rafael material at the Nuestra Senora (Cosala) mill facility, at a normal throughput of 2,500 tonnes per day (TPD). This new circuit, together with the existing circuit of 1,600 TPD, will easily handle the planned 2012 production increase to 4,000 TPD. The Cosala mill facility was originally designed for expansion and the existing primary crushing system and conveyors are more than sufficient for the 2012 ramp up. Modifications required for the expansion include the installation of an additional ball mill, flotation cells, thickeners, regrind mills and various pumps. The Company expects the plant expansion to be cost effective and completed by the end of the second quarter of 2011."

"In February 2008, an in-house Preliminary Economic Assessment Study (PEA) by Mine Development Associates of Nevada for Platte River Gold Inc. (now a wholly owned subsidiary of Scorpio) looked at open pit mining of the San Rafael body at a rate of 3,000 TPD. The Company has initiated work to augment the PEA for a pre-feasibility level study ("PFS") and design for a minimum of 2,000 TPD mining operation. To this end, the Company is in final planning for open pit infill drilling for mine planning, condemnation drilling for waste rock disposal, and geomechanical and hydrogeological drilling for rock mechanics of the pit walls and any potential water flow in the pit area. The results of this work will be incorporated in the final PFS, which is expected later this year. Importantly, the land on which the deposit sits is 100% owned by Scorpio, which will help accelerate the estimated 3-month permitting window."

"In closing, the Company has begun an aggressive expansion program aimed at reducing operating costs while increasing metal output over the next 2.5 years, at which time it expects to achieve intermediate producer status with respect to metals produced."

Forecast for the Year 2010 Metal Output:

    
    -   First quarter mill throughput exceeded the budgeted rate of 1,000 TPD
        at an average of 1,173 tonnes per operating day.

    -   Daily mill throughput is estimated to be 4,000 TPD; an increase of
        90% from the estimated 2011 mill throughput of 2,100 TPD.

    -   Yearly throughput is budgeted at 1.32 million TPY based on 330 days
        operating; an 82% increase from 2011.

    -   Lead output is expected to increase by 45% to ~18 million pounds from

        follows: Lead US$0.80 per lb; zinc US$0.80 per lb; copper US$2.20 per
        lb and silver US$13 per ounce.
