EXHIBIT L
RECLAMATION COSTS
The following Reclamation Cost estimate is based on the
assumption that there will be restricted no more than 20 . 0 acres ±
of disturbance at any-one time, as shown on the Mining Plan Map. The
mine working face will be 500 feet long by an average of 45 feet
high and would need cut/fill sloped at 23 .47 yd/lft . Finish
sloping on the 1200 feet of partially backfilled 2 : 1 slopes at
37 . 50 yd/lft to complete the 3 : 1 slope. The 20 acres will then be
resoiled with an average of 3 inches of soil using a scraper to
spread it and a blade to shape the seed bed. At that time we will
have to respread 8, 070 cubic yards of topsoil and move 11, 715 cy of
cut\fill sloping. The final backfill sloping and shaping on the
exterior slopes will require moving 45, 000 cubic yards of material .
The table below outlines the various areas of disturbance at the
time explained above. A D8N dozer is used to do the cut/fill
sloping, a 631G scraper will resoil and couplet bank sloping and a
140G Blade is used to shape the reclamation area. The mobilization
haul distance is 12 . 0 miles at a average speed of 45 mph. The
revegetation cost figure used includes fertilizer, grass seed,
labor and drilling costs .
