TORONTO , March 6, 2012 – Scorpio Mining Corporation (TSX:SPM.TO) (“Scorpio” or the “Corporation”) is pleased to report additional positive drill results from its San Rafael Development Project, favorably located only 19 kilometers by road from the Nuestra Señora processing facility in the Cosalá Mining District, Sinaloa State, Mexico .

“A total of 7,948 meters of drilling were completed at San Rafael in 2011 and so far in 2012 we have completed another 2,836 meters” stated Parviz Farsangi, President and CEO. “The continued positive drilling results coming out of San Rafael, which include some significant gold credits and the discovery of a new manto body, not only enhance the Corporation’s plans for expansion in the Cosalá Mining District, but also reflect the excellent work carried out by our technical team on the ground.”

Highlights from the latest San Rafael drill results include:

·         Hole SR-264: 288 g/t Ag, 0.23 g/t Au, 0.52% Zn, 0.75% Pb and 0.213% Cu over 15.2 m true width

·         Hole SR-279: 1,562 g/t Ag, 2.1 g/t Au, 1.53% Zn, 0.27% Pb and 6.119% Cu over 5.1 m true width

Previously the San Rafael mineral occurrence was thought to be composed of three distinct bodies hosted in skarn:

·         The Main Zone, which is a manto at the contact of skarn altered limestones and overlying rhyolites

·         The Upper Zone, which is a parallel and somewhat narrower body above the Main Zone; and

·         The 120 Zone, which is a steeply dipping body that intersects the Main Zone and trends northwest.

Drilling completed by Scorpio at San Rafael has focused on defining proposed open pit boundaries of the Main Zone and the in-fill drilling of widely-spaced intersections from prior drilling campaigns. Currently, drilling is following a fourth new manto-like body discovered to the northwest of the main deposit area.

This new manto body has the potential to add to the current mineral resource estimate reported for San Rafael, which is presented below:

Mineral Resource Estimate- San Rafael Deposit (August 12, 2009)

Note: Metal prices used in the above estimates are US$12/oz. silver, US$0.80/lb. zinc, US$0.70/lb. lead, US$2.00/lb. copper and US$750/oz. gold. A 3.5% zinc equivalent cutoff was applied to the Main & Upper Zones, and a 100 g/t AgEq cutoff applied to the 120 Zone. The NI-43-101 technical report to support this estimate was filed on SEDAR on Dec. 4 ^, 2009 and is available for viewing under the Corporation’s profile at www.sedar.com. Mineral resources which are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing or other relevant issues. The quantity and grade of reported Inferred resources in this estimation are uncertain in nature an there has been insufficient exploration to define these Inferred resources as an indicated or measured mineral resource and it is uncertain if further exploration will result in upgrading them to an Indicated or Measured mineral resource category.

San Rafael Development Project – Latest Drill Results

Note: Results for drill holes SR247-252 were released November 7, 2011 with gold results pending. NC is reported for true widths in areas where insufficient structural data was available to allow a calculation of true thickness.

Scorpio expects to complete drilling on all portions of the San Rafael Development Project by mid to late March, 2012. Upon receipt of all results and the technical review of the data, a new mineral resource estimate will be completed with the intent to upgrade a significantly larger portion of the resource to the measured and indicated mineral resource categories.
