The mine 1s located in Routt County, Colorado approximately ten (10) miles south of Hayden along County Highway 53 in sections 30 and 31 of TSN, R88W. The loadout for the mine is situated approximately two miles southeast of Hayden in parts of sections 10, 14, 15, 22 and 23 of 76N, R88W. The Hayden Gulch mine has been in existence since January, 1978, and is currently operating under a permit (C-003-80) issued on January 4, 1981 by the Colorado Mined Land Reciamation~Division (the Division).
