Exhibit "C" Exploration License No. COC -74911
Site Reclamation:
Upon completion of drilling and related activities, all drill holes will be backfilled, sealed and
abandoned. During drilling, fluid return will be monitored to identify the depth and extent of any water -
producing zones. Upon abandonment, in accordance with Drill Hole Plugging Procedures agreed to by
BLM and CDRMS. Bentonite chips or bentonite plug gel or similar seal will be established in the bottom
of the hole, extending to within ten feet of the surface. A cement plug will be set in the hole ten (10) feet
below the ground to within three (3) feet of the surface. Accumulations of drill cuttings and mud will be
backfilled into and buried in the mud pit (if any) or otherwise buried.
All trash and debris will be removed from drill sites for disposal. Excavations, including mud
pits, will be backfilled. Where mud pits are necessary, they may be temporarily fenced and allowed to
dry and/or backfilled with drill cuttings and/or previously excavated material. During backfilling, the
material will be mixed and compacted as it is replaced, by running the equipment over the backfilled area
during placement of successive lifts. Following backfilling, disturbance areas will be graded to their
approximate original configuration and surface drainage reestablished. Any salvaged topsoil materials
will be re- spread onto the regraded surface and reseeding of the areas (pads and roads) will take place
using the following seed mixture. A metal post with tag will be placed in the vicinity of the hole as a
permanent marker.
Seed application rates will be doubled if aerial broadcast methods are used
Seeding will take place in the fall or early spring. Monitoring of re-seeding efforts will occur for
a couple of field seasons to determine stand success, re- seeding requirements and control of any noxious
weeds.
Estimated amounts of coal to be removed during exploration
During the exploration drilling process a estimated 8 tons of coal will be recovered from this
area. This coal will occur in the form of coal core that is recovered, so that it can be analyzed to
determine its physical, chemical, and energy related properties, this will allow for the determination of
whether it is of sufficient quality, and quantity to allow Oxbow to apply for a coal lease in this area.
Coal tonnages removed were calculated by estimating the volume of coal to be removed from each
exploration drillhole, times the typical weight of coal at 80 # /cu.ft. as shown below:
Volume of coal removed: V= 7 r 2 h
r = 3 inches, h = 12 ft. ave. per seam assume 2 seams of coal encountered.
Estimated tonnage = 8.01 tons of coal removed during exploration drilling process.
