Vancouver, August 13, 2007 - Scorpio Mining Corporation (TSX:SPM) is pleased to report addition underground drill results from the 10th Level of its 100% owned Nuestra Senora deposit, Sinaloa State, Mexico.

Peter J. Hawley, Chairman, CEO reports, "The exploration and definition drilling from the 10th level of the Nuestra Senora deposit, approximately 210 metres vertically below surface, correlates very well to that of the previously reported drilling from the 8th and 9th levels (see news release of July10, 2007). In addition, the company continues to find extensions to the Nuestra Senora mineralization at the periphery of the deposit. All of the mineralization found to date in the Nuestra Senora and nearby satellite deposits is accessible by underground development, and exploration continues to expand the mineral inventory. The Company continues to be very impressed by the robust nature and extent of mineralization within a relatively small area."
