EASTERN MINING DISTRICT
<br />• The proposed permit revision will add approximately 7,680 acres to the permit area, of which approximately 4,440
<br />aches (58%) are associated with the Eastem Mining District. The additional acreage was added to square up the permit
<br />area and accommodate future panels to the north of the Eastem Mining District. The schedule for mining the Eastem
<br />Mining District and the remainder of the districts within the permit area is provided on Map 23, Mine Plan.
<br />The mine plan for the Eastem Mining District is shown on Maps 23. Prior to mining this coal, a new federal lease will
<br />have to be issued for the coal in the following described parcels:
<br />Township SN, Ran eg 86W
<br />Section 21 - N/2, SEl4;
<br />Section 22 - W/2, E/2EJ2;
<br />Section 23 -ALL;
<br />Section 26 - NW/4, NW/4NF/4, and N/2SW/4;
<br />Section 27 - W/2;
<br />Section 28 - NF/4, E/2NW/4; and
<br />Section 33 - NF/4NE/4.
<br />The lease application was submitted on Febmary 1, 1993, and the lease has been issued with an effective date of
<br />Febmary 1, 1996.
<br />Cyprus has acquired the fee coal, located in the Eastern Mining District. During this period, the state coal has been
<br />transferred to Cyprus. Coal ownership is shown on Map 2.
<br />• During the fivo-year permit term (1993 - 1998) covered by this application, mining will continue in the Southwest
<br />Mining District and extend from the present northern extent of the north mains in Section 20, TSN, R86W,
<br />approximately 8,300 feet into Section 17, TSN, R86W. Development mining will occur in gateroads 5 Right through
<br />10 Right, submains in Sections 28 and 29, including 1,000 feet ofdevelopment mining in gateroads 2 Right through 4
<br />Right. The submain will be developed off the 6 Right gateroad and will include up to six entries driven on
<br />approximately 100-foot centers and approximately 5,500 feet in length. When the submains come off the north
<br />mains, up to 7 entries will be driven, plus a sump, as shown on Map 23. A single entry may be driven off the recovery
<br />room for each longwall panel to facilitate longwall moves. This entry will be of similar geometry as the gateroad
<br />entries. Also, an additional entry will be driven at the intersection of the submains and gateroads to facilitate driveage
<br />and recovery operations. These entries are typically less than 100' in length and then turn to the south and tine in with
<br />the gateroad. Longwall mining will occur in panels 9 Right, 8 Right, and 7 Right. These mining areas are shown on
<br />Map 23, Mine Plan, and each mining process, i.e. longwall or development, is designated by a unique pattern on the
<br />map. The 9 Right, 8 Right, and 7 Right longwall panels will involve mining of coal contained in State of Colorado
<br />Lease CO-3229, Federal Coal Leases C-081330 and COC-54608, and fee coal owned by Cypms Western Coal
<br />Company. Gate roads 10 Right, 9 Right, 8 Right, and 7 Right will mine coal from the same parcels as described
<br />above for the longwall panels. The 6 Right gateroad will mine coal from the same leased and fee coal described in
<br />addition to coal mined from Federal Lease D-052547. The 5 Right gateroad will mine coal from Federal Leases C-
<br />081330, COC-54608, and fee coal owned by Cypms. The submains will see coal mined from Federal Leases D-
<br />052547 and C-081330 and private coal owned by Twentymile Coal Company in the SW/4 of Section 28. The North
<br />Mains will mine coal from Federal Coal Lease C-081330, fee wal owned by Cypms, and from coal in State Lease C-
<br />609. The remaining five-year blocks are shown on Map 23. The surface ownership for the Eastern and First North
<br />Mining Districts is shown on Map 1, Surface Ownership. The render is referred to this map for location of the parcels
<br />owned by the various companies, individuals, or governmental entities.
