Scorpio Mining Completes Phase I Drill Program at La Revancha

Toronto, April 30, 2012 - Scorpio Mining Corporation (TSX: SPM) ("Scorpio Mining" or the "Corporation") reports final results from the recently completed 4,068 meter Phase I drill program at its 100% owned La Revancha Project, Chihuahua State, Mexico.

The La Revancha project is located in the Parral Mining District, which has a mining history dating back to colonial times and hosts several significant silver deposits and operating mines. At La Revancha, over 1.5 kilometers of steeply dipping, north-south oriented veins have been identified at surface. Mineralization is hosted in silicified breccia and replacement zones filling fractures and faults. At least three veins are observed: La Revancha, El Alto and San Nicholas. Drilling to date of the La Revancha and El Alto vein systems has indicated reasonably consistent mineralization over a strike length of at least 500 meters and possibly up to 700 meters, including one identified gap in the mineralization. Mineralization has been tested up to 250 meter vertical depths. It remains open at depth, at least 100 meters to the south and at least 300 meters to the north.

The near vertical nature of the mineralizing system and the fact that nearly all mineralization drilled to date is above the valley floor indicates the potential for relatively easy development and mining in the future.

Final results of holes LAR-42, -43, -46 and -59 as well as previously reported holes (press release - March 5, 2012) are presented below.

* Previously reported in the Corporation's March 5, 2012 press release.
** NC is reported for true widths in areas where insufficient structural data was available to allow a calculation of true thickness.

A follow on program of at least 2,000 meters is planned beginning in late June or July 2012. Subject to results, the Corporation anticipates conducting a preliminary resource calculation for this project by year end.

With completion of the first phase of drilling at La Revancha, the Corporation has commenced a 2,500 meter drilling program at the nearby Tepozán Project.
