Geological Setting, Deposit Types and Mineralization.
The coal deposits in the eastern USA are the oldest and most extensively developed coal deposits in the country. The coal-bearing formations on the properties are Carboniferous in age, being in the Pennsylvanian system, which includes the Monongahela, Conemaugh, Alleghany, and Upper Pottsville groups. These coal-bearing formations contain two-fifths of the nation’s bituminous coal deposits, extend over 900 miles from northern Alabama to Pennsylvania, and are part of what is known as the Appalachian Basin. The Appalachian Basin is more than 250 miles wide and in some portions, contains over 60 coal seams of varying economic significance. Seams are typically between 1 foot and 6 feet in thickness, with relatively little structural deformation. Coal in the region is classified as high- to low-volatile bituminous with rank increasing to the east. Coals are typically characterized as low to medium sulfur and high heat content.

Mineralization.
Mineable coal seams within the properties are typically low-ash, low to high-sulfur, and high- thermal content bituminous coals. Regionally, the coals are typically low-volatile in rank, with rank increasing from west to east. The maximum seam thickness may reach over 6.0 feet where multiple coal benches occur in proximity to one another; however, the average mineable thickness of the seams in this evaluation generally ranges from 1 foot to 4 feet. Seams are generall ........

The proposed A-Seam mine is scheduled to begin production in 2032. The Brookville A seam is accessed via box cut entry along the outcrop. This mine is projected to be a metallurgical coal operation on leased mineral property.

Production is scheduled for 255 days each year, which represents production on Monday through Friday. On each day, two production sections are scheduled to produce coal on two shifts; the third shift is reserved for maintenance and mine conveyor belt and power moves. The sections are configured as regular sections with one continuous miner available for production on each section. Productivity is planned at the rate of 180 feet of advance per shift of operation. A total of 101 employees are assigned to the mine.

Principal production equipment includes two continuous miners, four roof bolters, six shuttle cars, and two scoops. Coal is extracted from the production face with the continuous miner and hauled to the mine conveyor in shuttle cars. At the conveyor belt, the coal is discharged from the shuttle cars onto a feeder breaker for transfer onto the conveyor. The conveyors carry the coal to the outside, where it is stacked on the ground to await truck transport to the preparation plant and load-out. The truck haul distance is approximately 10 miles.

Expected annual production averages approximately 593,000 marketable tons at steady state.

The mine is scheduled to operate from 2032 and terminate during 2045.
