T. 18 N., R. 101 W., 6th P.M., Wyoming 

                        Section 34: E                        1/2                        , E                        1/2                        NW                        1/4                        , SW                        1/4                        ;                     

Containing 1,399.48 acres more or less.

All of the acreage applied for has been determined to be suitable for surface mining. There are no existing surface facilities or structures that will be impacted by the proposed pit. There are no producing oil and/or gas wells on the tract. All of the surface and mineral estate on the LBA tract is controlled by the BLM. 

The tract contains surface mineable coal reserves within the Upper Cretaceous Almond Formation. In the LBA area, the coal cropline extends roughly southwest to northeast along the northwestern edge of the proposed pit. 

Mining is expected to begin along this cropline. The coal seams dip more rapidly than the ground surface toward the southeast and an economic cutoff of about 200 feet of overburden is projected for the final mine cut. 

Numerous coal seams occur in the immediate area, but only four are considered to be mineable within the proposed pit. These are identified, in descending order, as the AG, AF, AFL, and AE seams. The AG is the uppermost seam and is the most consistent over the LBA, generally ranging from 4-6 feet thick. The interburden between the AG and AF seams ranges from about 5-40 feet thick on the LBA. The AF seam ranges from 2-12 feet thick on the LBA and is joined with the AE seam near the cropline in Section 4. The AFL seam is a localized split that is largely confined to Section 34. The parting between the AF and AFL seams ranges from 0-20 feet thick and the AFL seam itself ranges from 2-3 feet thick on the LBA. The interburden between the AF and AE seams ranges from 0-45 feet thick on the LBA. The AE seam varies from 2-8 feet thick on the LBA. The composite mineable coal thickness ranges from 10-20 feet thick over the LBA. 

The LBA tract contains an estimated 11,218,740 tons of mineable coal in the four seams described above that could be recovered by surface mining methods. This mineable reserve is based on a minimum 20 foot overburden thickness to avoid any coal oxidation areas, a minimum coal thickness of 2 feet, and a maximum stripping ratio of 14.6:1 (bank cubic yards per ton of coal). Other coal seams and splits are found in the LBA area, but these have not been included in this reserve estimate due to thickness, depth, poor quality, limited areal extent, or any combination of factors. 

Potential bidders must establish their own practicable criteria for mining, including their estimate of recoverable reserves based on multiple seams and thin seam mining. 

The Pit 14 LBA coal is ranked as subbituminous B. The overall average quality is approximately 9965 BTU/lb with about 7.57% ash and 0.54% sulfur. These quality averages are generally higher than those for the coal reserves currently being mined at the adjacent surface mine. 

                    The tract will be leased to the qualified bidder of the highest cash amount provided that the high bid meets or exceeds the BLM's estimate of the fair market value of the tract. The minimum bid for the tract is $100 per acre or fraction thereof. The bids should be sent by certified mail, return receipt requested, or be hand delivered. The Cashier will issue a receipt for each hand-delivered bid. Bids received after 4 p.m., on Monday, June 4, 2007, will not be considered. The minimum bid is not intended to represent fair market value. The fair market value of the tract will be determined by the Authorized Officer after the sale. The lease issued as a result of this offering will provide for payment of an annual rental of $3.00 per acre, or fraction thereof, and of a                           ( print page 23844)                        royalty payment to the United States of 12.5 percent of the value of coal produced by strip or auger mining methods and 8 percent of the value of the coal produced by underground mining methods. The value of the coal will be determined in accordance with 30 CFR 206.250.                 

Bidding instructions for the tract offered and the terms and conditions of the proposed coal lease are available from the BLM Wyoming State Office at the addresses above. Case file documents, WYW160394, are available for inspection at the BLM Wyoming State Office.
