NORTH THOMPSON CREEK MINES (a) 1991 Annual Reclamation Report Permittee: Minrec, Inc. 2768 Compass Drive, Suite 101 Grand Junction, CO 81506 Permit No. C-81-025 (b) No land was disturbed during 1991 except where an open channel spillway for sediment pond 9 was installed and a small area along the embankment of the long pond. (c) No land was backfilled during 1991. (d) No land was topsoiled during 1991. (e) No land was seeded or cultivated during 1991 except the small area that was disturbed where the open channel spillway for sediment pond 9 was installed. (f) The disturbed areas associated with the North Thompson Creek Mines were reclaimed during 1986 and 1987. In the fall of 1986 the refuse pile was seeded and mulched. In the fall of 1987 the remainder of the mine site was seeded and mulched and the unit train loadout was seeded. Following is a table which shows the location, number of acres and date of planting for all previously revegetated areas. All seeding was done in the fall of the year. Location Acres Year Seeded Refuse Pile 8.0 1986 Mine Sites 30.7 1987 Truck Dump 1.9 1987 Unit Train Loadout 24.5 1987 (g) A vegetation study was performed at the mine site and the unit train loadout. The study at the mine site, which is enclosed, was performed to determine if the cover at the mine site was adequate to control erosion. The cover at the mine site averages 46.28 which is quite good although no comparison was made with the adjacent area so a soil loss comparison was not prepared. The study at the unit train loadout was performed to demonstrate that the vegetation is adequate to control erosion. This study 2.04.13 supports a land use change request, technical revision application, TR-012.
