Final EIS For Graymont Mine Expansion Available For Review

The Final Environmental Impact Statement for the proposed Graymont Mine expansion is now available for public review. The Bureau of Land Management and the Montana Department of Environmental Quality have posted the Final EIS at their websites: and

The proposed mine expansion is on unpatented mining claims on public lands west of Townsend, Mont. The expanded operation would be a continuation of mining along a prominent limestone ridge which forms the crest of the “Limestone Hills.”  Mining was originally permitted here beginning in 1981 and has continued ever since.

Alternatives proposed in the EIS were developed collaboratively with other agencies and with public involvement.

The proposed expansion would add another 1,940 acres to the permit and an additional 1,313 acres of surface disturbance. The principal concern, developed through public meetings and agency review, was the potential loss of mule-deer and mountain-sheep habitat and winter browse vegetation, primarily mountain mahogany. The Preferred Alternative in the Final EIS ensures long-term regeneration of the existing mule deer and bighorn sheep populations in the winter range in the Limestone Hills. This Alternative, also called the Modified Pit Backfill, provides for more diverse topography and soils that favor winter browse species.

The BLM's mission is to sustain the health, diversity, and productivity of America’s public lands for the use and enjoyment of present and future generations.
