Molycorp proposes to construct and operate a molybdenum tailings disposal facility on 1,230 acres of public land near Questa, New Mexico ... the project would consist of a 568-acre tailings pond in the saddle of Guadalupe Mountain. The pond would be formed by the construction of two rock-filled dams at either end of the saddle. Other facilities would include a tailings pump station, an extension of the tailings pipeline, tailings distribution lines, access roads and a patrol road, a powerline, a seepage collection pond, surface water diversion channels, and a decant water channel. The project would provide additional storage for approximately 200 million tons of tailings from Molycorp's molybdenum mine located approximately 12 miles east of Guadalupe Mountain.
