Mines Management Receives Strong Support for the Montanore Adit Reopening from Montana Governor's Office and Local Community.

SPOKANE, Wash. -- Mines Management, Inc. (AMEX:MGN) (TSX:MGT) is pleased to announce it received strong support from the community of Libby, Montana, and the office of the state's Governor in a ceremony marking the re-opening of the Libby Adit.

In a presentation by the Governor's State Director of Economic Development, Mr. Evan Barrett, he commented, "This mine is not only good for Libby and Lincoln County, but for the State of Montana. There is a way to do mining right, that is what is refreshing about this project. It is the first major step to return quality jobs to this county."

The ceremony was attended by, among others, Lincoln County Commissioners, Libby Mayor and City Council members, Lincoln County Port Authority, Troy City Council members, U.S. Forest Service officials, local business leaders and town's people, representatives from the Governor's office and management of the Company.

The re-opening of the Libby Adit signals the commencement of a two-phase project to rehabilitate the tunnel and conduct an underground drilling and evaluation program. The Libby adit was originally constructed and partially completed between 1988 and 1991 by the former operator of the Montanore Project, Noranda Minerals Corp. The adit was advanced to a length of approximately 14,000 feet prior to cessation of activities. Once the tunnel has undergone rehabilitation, and necessary infrastructure replaced, the Company plans to advance the tunnel 3,000 feet and initiate a 35,000-foot diamond core drilling program. The project is estimated to take approximately 24 months, and would employ up to 30 people.

The first phase of the project, reopening the portal and conducting preliminary evaluation of its condition, was recently completed. The second phase of the project, which includes dewatering, installation of necessary infrastructure, rehabilitation, advancement of the tunnel, and a diamond drill program, is subject to approval based upon results of the preliminary evaluation by the Montana Department of Environmental Quality.
