Mine Area 1 will be downgraded from the approximate 80 foot wide mine haul road to a 20 foot wide dirt road. Topsoil will be replaced on cut and fill slopes needed for the reclaimed road as well as the disturbance from the operations haul road and these areas will be revegetated. Also at the end of mining, the main haul road to Mine Area 2 will be reclaimed in the same manner. All other mine roads needed to access the various mine facilities will be reclaimed upon completion of use of the facility. The road reclamation will occur in conjunction with the associated facility reclamation.

13.7.4 Utilities The two utilities located at the site will be power facilities and telephone facilities. Both utilities will be brought onto the site through underground lines. Upon completion of mining activities these utilities will be disconnected leaving the underground lines in place.

13.8

Reclamation Timetable

Reclamation will occur as contemporaneously as practicable with the mining operation; however, it will be limited in the first 5 year term do to the DMLW’s request to minimize the amount of disturbance within the permit area. The placement of overburden stockpile 1 and 2 on the previously mined and backfilled pit areas will minimize the amount of disturbance required for the mining operations but will also limit contemporaneous reclamation in the first 5 year term.. Reclamation will run concurrently with the mining operation once overburden stockpile 2 is complete and will continue through the mine life...

13.9

Reclamation Costs

The estimated reclamation costs for each year of the mining operation are outlined in the following incremental bond schedule. Before operations commence on each increment, a bond for the specified amount will be filed with the Division of Mine, Land and Water (DMLW). Year “0” addresses some minor predevelopment involving the construction of a pioneer trail within the permitted corridor for the mine access road and the completion of one drill hole.
