The Company has been given a mandate by its Board of Directors to proceed into production based on the review of the positive results from the PFS (see news release of June 14, 2007)

The PFS projects that the base case cash operating cost of producing silver at the Nuestra Señora project, after accounting for by-product credits, will be a negative US$0.98 per ounce produced, using discounted metal prices.

Peter J. Hawley, Chairman, CEO comments, "After reviewing the PFS and given the project's strong economics, particularly the current metal price scenario which shows a 60.7% Internal Rate of Return (IRR), along with the upside potential to increase mineral reserves and resources, it is the Company's view that we have to get this project into production as soon as possible to take advantage of the current strong metal prices. With the recent additional staffing of a Mill Superintendent, Mill Construction Manager, Chief Production Geologist and the awarding of mill construction contracts we are in a position to aggressively push the project forwards towards commencement of production as scheduled for March, 2008. We look forward to providing ongoing updates of our surface exploration results, underground development and exploration work and our progress on the mill facility construction as we approach the start up time line."

President, Mr. D. Roger Scammell, PGeo, is the Company's Qualified Person for the Nuestra Señora project. Mr. Scammell is responsible for the current exploration and development program and has reviewed the content of this release.

ON BEHALF OF SCORPIO MINING CORPORATION
