Background on Mine

The Bowie #2 mine began commercial production in November 1997 and has a capacity of 6 million tons per year.

Bowie's primary product is a high Btu, low sulphur run-of-mine steam coal. The coal can be supplied as a stoker product. Mining is done underground in the thick Paonia Somerset "B" and "D" seams. Recoverable reserves presently leased exceed 100 million tons. The property has 60 million tons under permit.

The Bowie #2 mine utilizes continuous miners for development and plans to install a longwall mining system in November 1998. The longwall will mine in both the "B" and "D" coal seams. Demonstrated low cost production, coupled with high-Btu, low-sulphur product will make this a product in demand by the electric utility industry.

The Bowie #2 mine is all salaried, union-free organizations. Employees are also eligible to participate in production and safety incentive programs. A high percentage of the workforce holds mine foreman papers. This, along with their demonstrated safety and productivity, makes them one of the most skilled workforces in the industry.

A modern, fast-loading system complements the capacity and productivity of the mine operation. Over 21,000 tons of closed storage at the train loadout site assures loading of 100 car trains in under two hours per train.

With a proven production and safety record and long-term reserves in hand, the Bowie #2 mine should remain one of Colorado's primary producers well into the 21st century.
