Scorpio Mining Announces 2013 Exploration Program

TSX: SPM

VANCOUVER, April 4, 2013 /CNW/ - Scorpio Mining Corporation (TSX: SPM) ("Scorpio Mining" or the "Company") announces its planned 2013 exploration program, which will concentrate on developing new resources within and around the Nuestra Señora Mine and explore for new resources within its 100% owned 26,819 hectare land package in the Cosalá District, Sinaloa, Mexico.

The Company has planned 11,500 meters of both surface and underground drilling at the Nuestra Señora Mine to investigate new areas and to further define and upgrade areas with currently defined "inferred resources". Drilling is active in the main Nuestra Señora zone below the 12^th level. Down-hole geophysics is being contemplated to further refine targeting in this important area of investigation.

A 5,000 meter surface drilling program has also commenced to test the Venado, Los Cristos, and San Ramon targets, where significant silver-lead-zinc+/-copper mineralization has been identified in either outcrop, drill core or historical workings. Located within 3 to 16 kilometers of the Nuestra Señora processing facility, these high priority targets, could potentially lead to building the resource base and enter the growth pipeline of development projects. A location map is available at: www.scorpiomining.com/i/maps/pr/CosalaDistrictExpl.jpg.

The Company has engaged Terraquest Ltd. of Markham, Ontario to complete a 1,150 line kilometer heli-borne magnetic, radiometric and EM-VLF survey that will cover a significant area centered on the San Rafael and El Cajón development projects. This will be the first geophysical survey ever conducted in the area, with the intent to characterize the numerous existing targets and potentially identify new targets based on geophysical signatures. Detailed mapping and geochemical sampling of select areas within and around this grid is also underway.

The Company has also commissioned an ASTER alteration study using new satellite imagery to identify mineralogical alteration zones related to structures throughout the entire concession area. The current understanding of controls to mineralization in the district is that structural features such as fault zones and related dilational zones provided the main conduit for mineralizing fluids as well as structural traps for the emplacement of mineralization. The information gained from the ASTER survey in conjunction with other surveys will greatly enhance geological interpretation and drill targeting.

The planned 2013 exploration program is budgeted at $5.2 million. Follow-up programs will be planned based on success of the drilling and results from the numerous surveys underway.

Peter J. Hawley, Scorpio's Interim President & CEO comments, "Our goal this year is to step out and delineate new targets in the district using advanced remote sensing technology and detailed ground studies, and apply the information gained to identify high priority targets that could potentially add to the overall resource base in the near term. This holistic approach has never been applied to the Cosalá District, where all known showings and deposits to date were discovered by surface prospecting. Our mandate is to put projects into the development pipeline, and to do so we will employ all information gathered to focus on those targets having the most solid technical attributes and best potential for advance."
