Mines Management, Inc. (NYSE-Amex:MGN)(TSX:MGT) is pleased with the recent advances made by the government agencies in their selection of the preferred alternative for the transmission line proposed for the Montanore Silver-Copper Project.

Mines Management’s President and CEO, Mr. Glenn Dobbs, stated, “Getting to this phase on the transmission line is a major and welcome milestone in the process to re-permit the Montanore project, and reflects the significant progress we have made this year. We continue to work closely with the agencies on the remaining facets of the plan as we progress toward conclusion of the Final Environmental Impact Statement (“EIS”) and Record of Decision (“ROD”), and anticipate additional progress as we move further through the final phase of permitting the Montanore.”

As part of the environmental review process, the agencies considered a variety of alternatives for the location of the transmission line, and, based partly upon public comment received following review of the Draft EIS, modified the various alternatives considered for the project. Following further analysis, the agencies made a determination as to their preferred alternative for the transmission line that will be advanced in the remaining environmental review process. This is not a final decision, but it is a critical step in the continued advancement of the review process.

The selected alternative for the transmission line minimizes impact to critical habitat for many species including grizzly bears, bull trout, and old growth timber, as well as preservation of the visual natural attributes of the region.
