BRIGUS GOLD CORP. ANNOUNCES FILING OF PRELIMINARY PROSPECTUS

(Not for distribution to United States newswire services or for dissemination in the United States)

Halifax, Nova Scotia; October 4, 2010 – Brigus Gold Corp. (“Brigus Gold” or the “Company”) (TSX and NYSE Amex: BRD) announced today that it has filed a preliminary short form prospectus in respect of the previously announced bought deal offering. The Company entered into an underwriting agreement dated October 1, 2010 with a syndicate of underwriters led by Haywood Securities Inc. (the “Lead Underwriter”) and including Cormark Securities Inc., BMO Nesbitt Burns Inc., CIBC World Markets Inc., Jennings Capital Inc., Paradigm Capital Inc. and Brant Securities Limited (together with the Lead Underwriter, the “Underwriters”). Pursuant to the underwriting agreement, the Company has (i) agreed to sell and the Underwriters have agreed to purchase 30,000,000 units (“Units”) of Brigus Gold at a price of C$1.50 per Unit, and (ii) appointed Haywood as agent to offer for sale, on a guaranteed agency basis, up to 2,941,177 Flow-Through Shares at a price of C$1.70 per Flow-Through Share (collectively, the “Offering”). Each Unit will consist of one common share (“Common Share”) and one quarter of one common share purchase warrant (each whole warrant a “Warrant”), with each Warrant entitling the holder to acquire one Common Share at a price of C$2.19 expiring November 19, 2014.

The Company will use the gross proceeds from the sale of the Flow-Through Shares to incur flow-through expenditures for its Canadian projects located near Timmins, Ontario and Uranium City, Saskatchewan which qualify as 100% Canadian Exploration Expense (“CEE”), and will renounce such flow-through expenditures to the investors for the taxation year ending December 31, 2010.

After deducting expenses related to the Offering, the Company plans to use C$5 million of the net proceeds from the sale of the Units for working capital with approximately 50% of the balance used to reduce outstanding project debt related to the Black Fox project and 50% of the balance used to reduce the Company’s existing gold hedge commitments.

This press release shall not constitute an offer to sell or solicitation of an offer to buy the securities in any jurisdiction. The securities will not be and have not been registered under the United States Securities Act of 1933, as amended, and may not be offered or sold in the United States absent registration or applicable exemption from the registration requirements.
