RUBICON ANNOUNCES SECONDARY OFFERING OF ITS COMMON SHARES

Rubicon Minerals Corporation has filed a preliminary short form prospectus in all the provinces of Canada except Quebec in connection with an overnight-marketed secondary offering (the "Offering") by Evanachan Limited and McEwen Trading LP (the "Selling Shareholders"), entities owned or controlled by Robert R. McEwen, of 45,714,357 common shares of Rubicon owned by the Selling Shareholders. The Offering will be conducted by GMP Securities LP.

The Offering will be priced in the context of the market with the final terms of the offering to be determined at the time of pricing. It is intended that upon completion of the offering, the Selling Shareholders will own no common shares of the Company. Rubicon will not receive any proceeds from this Offering. Closing of the Offering is expected to occur on or about October 5, 2010 and is subject to certain conditions, including the approval of the Canadian securities regulatory authorities.

The board of directors of Rubicon has formed a special committee to advise the board of directors in connection with the Offering. The special committee has retained BMO Capital Markets as its financial advisor.

Rob McEwen said "Rubicon was and continues to be a great company. They have excellent management, an important discovery, and a strong treasury with which to explore and develop it. The Company has grown to represent a disproportionate share of my stock portfolio for an investment where I am not actively involved in management. This step is designed to focus my interests in the companies I run, US Gold Corporation and Minera Andes."
