2014

Toronto, June 2, 2014 - Scorpio Mining Corporation (TSX: SPM) ("Scorpio" or the "Company") today announced that Tocqueville Asset Management, L.P. and The Tocqueville Trust (collectively, "Tocqueville") have agreed that they will not pursue the nomination of their own candidates for election to the Company's board of directors at Scorpio's 2014 annual meeting of shareholders, to be held on June 12, 2014. As a result, the Company has agreed to discontinue its recently commenced legal proceeding against Tocqueville concerning the validity of Tocqueville's intended director nominations.

"We are pleased to see Tocqueville stand down from its attempt to take control of the Company's Board at our annual meeting," said Ewan D. Mason, Chairman of the Company. "However, we cannot ignore Tocqueville's disruptive actions and we call on all of our shareholders to show their support for the positive momentum at the Company and vote in favour of our director nominees at the annual meeting."

On May 12, 2014, Tocqueville delivered to the Company a notice of its intention to nominate three new individuals for election to the Company's Board at the 2014 annual meeting, in addition to its current nominee, Thomas Weng, who is already on the Company's Board, to give Tocqueville four nominees on Scorpio's seven-member Board. The Company brought the above described legal proceeding as it believed that Tocqueville's notice did not comply with the advance notice provisions of the Company's By-Laws respecting the nomination of directors and was therefore invalid.
