The Mesquite Mine began operations under an approved plan of operations during 1985. Since this time, plan modifications and expansions have occurred, which are summarized within the approved Mesquite Mine consolidated plan of operations dated October, 1995. On November 30, 1998, Newmont Gold Company, operator of the Mesquite Mine, submitted a plan of operations for an expansion of the mine. The existing mine site encompasses 5,200 acres, of which 3,655 acres have been disturbed by mining activities to date. The total area proposed for disturbance under the expansion is 693 acres, of which 190 acres would be new, unpermitted disturbance.

The expansion would allow the company to continue extracting and processing economical gold deposits, delineated by drilling programs initiated during 1988 and continuing to date. Current ore reserves would be depleted by the end of year 2000, while expansion would increase the mine life a projected seven years into year 2006. The plan modification proposes to process approximately 89 million tons of ore and 242 million tons of waste rock. The Big Chief and Rainbow pit expansions would encompass approximately 350 acres of Federal, State and private (patented) land, of which 76 acres would be new, unpermitted land disturbance. The plan modification also describes alternative methods for storage of waste rock, either in existing mined-out open pits, at new or expanded out-of-pit storage areas, or a combination of both; and construction of ancillary facilities including roads, fencing and drainage diversions.
