NEWS RELEASE

AUREUS ANNOUNCES UNDERWRITING AGREEMENT IN CONNECTION WITH UPSIZED OFFERING TO RAISE APPROXIMATELY US$16.0 MILLION

Aureus Mining Inc. ("Aureus" or the "Company") announces that in connection with its previously announced offering on 2 October 2013, it has entered into an underwriting agreement (the "Underwriting Agreement") with GMP Securities L.P., Clarus Securities Inc., RBC Europe Limited and Numis Securities Limited (the "Underwriters") to sell 30,900,000 common shares (each, a "Share") at a price of £0.32 per Share (the "Offering Price") pursuant to a private placement offering for gross proceeds of approximately £9.9 million (approximately US$16.0 million) (the "Offering").

The net proceeds of the Offering will be used to advance focused exploration activities within the Company's Bea Mountain Mining License, involving follow up drilling campaigns at Weaju and Ndablama gold targets, and for general corporate purposes.

The Company has granted the Underwriters an over-allotment option (the "Over-Allotment Option") to purchase up to 4,635,000 Shares at the Offering Price to cover over-allotments, if any, made by the Underwriters in connection with the Offering and for market stabilisation purposes on the AIM Market of the London Stock Exchange plc ("AIM"). If the Over-Allotment Option is exercised in full, the total gross proceeds of the Offering will be approximately £11.4 million (approximately US$18.4 million). The Over-Allotment Option is exercisable in whole or in part, at any time and from time to time, for a period up to two business days before the closing of the Offering.

The closing of the Offering remains subject to certain conditions including, but not limited to the receipt of all necessary approvals, including by the Toronto Stock Exchange ("TSX") and AIM. The closing of the Offering is expected to occur on or about 10 October 2013, or such other date as the Company and the Underwriters may agree. The Offering is also conditional upon the Underwriting Agreement not having been terminated.

The Shares issued to Canadian residents will be subject to resale restrictions under Canadian securities laws for a period of four months plus one day from the Closing of the Offering. Subject to applicable securities laws, the Shares issued to residents of countries other than Canada pursuant to the Offering may not be sold, transferred or otherwise disposed on the TSX or, except pursuant to an exemption from the prospectus requirements under Canadian securities laws, to any person in Canada or otherwise into Canada for a period of four months plus one day from the date of the closing of the Offering.

Director Participation

Pursuant to the Offering, certain directors of the Company have committed to subscribe for Shares in the Offering at the Offering Price as follows:
