Toronto, December 04, 2014 - Scorpio Mining Corporation (TSX: SPM) ("Scorpio" or the "Company") today announced completion of a purchase option agreement for the Cosalá 2 Concession ("the Concession"), in the Cosalá District of the State of Sinaloa, Mexico.

The Company will be required to disburse limited yearly amounts over a period of up to 10 years following an initial payment of about US$13,000. All future annual payments will be contingent on the Company having obtained the required permits to carry out a surface diamond drilling exploration program. The preliminary mapping and sampling of the Concession has indicated several areas of similar geology to the Nuestra Señora deposit.

Pierre Lacombe, President & CEO of the Company commented: "The Cosalá 2 concession covers 305 ha and is bordering on the south, east and west sides our current land package from where our producing Nuestra Señora Mine and the historical Candelaria Mine are located. It is therefore deemed to be a highly prospective area to find additional resources, similar to those mined from these deposits. We are looking forward to tap into the exploration opportunities that such an agreement will provide."

Scorpio Mining's President and CEO, Mr. Pierre Lacombe, Eng., is a Qualified Person as defined under National Instrument 43-101 and has reviewed and approved the content of this release.

ON BEHALF OF SCORPIO MINING CORPORATION

President & CEO
