Description:
This project is posted in the interest of transparency and response to Executive Order 14241.
The project sponsor proposes to construct, operate, reclaim, and close an underground mining and precious metal milling operation known as the Grassy Mountain Mine Project.
The project would consist of a mine and process plant area and a project access area. Access to the mine would be along an existing road, though road improvements would need to be made to accommodate large mining vehicles. The project sponsor proposes to mine approximately 2.07 million tons of mill grade ore and 0.27 tons of waste rock for a mine life of approximately 8 years. The project would result in approximately 487.9 acres of proposed surface disturbance on 18.9 acres of private land and 469 acres of public land.
