The geology of the properties is consistent with regional trends. Coal seams of economic importance on the properties typically range from 1 foot to 6 feet in thickness and are primarily low-volatile in rank. There are 11 coal seams on the properties that demonstrate reserve or resource potential including (not all of which are included within this report), in descending stratigraphic order: Sewickley, Redstone, Pittsburgh, Bakerstown, Upper Freeport, Lower Freeport, Upper Kittanning, Middle Kittanning, Lower Kittanning, Brookville, and Mercer.

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 generally continuous, but may be locally absent. Secondary discontinuity due to erosional features is present in most areas, resulting in seam outcropping, or visible exposure of the seam at the surface. Other than oxidation of the coal exposed at the surface, erosion of the seams has no significant impact on the mineralized deposits. Mineable seams associated with the properties are generally outcrop-accessible. Coal seams are characterized by both single-bench and multiple-bench coal horizons with parting (non coal) material varying by seam and area. Seam parting is common within the coal seams on the properties with intra-seam parting material increasing drastically in some areas. Roof strata are typically shale or sandy shale with zones of sandstone roof being common. Floor strata are typically sandstone, shale, sandy shale, fireclay, or in the case of the Upper Kittanning, limestone.

Limestone beds occur within the various stratigraphic groups of the region. Some of these limestone beds are extracted in conjunction with surface mining of the Sewickley coal in particular.

The proposed A-Seam mine is scheduled to begin production in the first quarter of 2029. 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 97 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 602,000 marketable tons at steady state.

NAPP currently operates two preparation plants, the Cambria Plant and the Shade Creek Plant, and has one preparation plant temporarily idled, the Rockwood Plant.

The Cambria Preparation Plant is designed for 400-tons per hour (tph) raw coal feed. It was relocated from its original site in 2009 incorporating design upgrades at that time. Raw coal at the Cambria plant is crushed screened to provide sized material to each of the following process circuits.

The Cambria complex has the capacity to store 120,000 tons of clean coal. The plant is serviced by CSX and has a unit-train loading capacity of 2,000 tph and can load a 130-car unit train. The power requirement for the Cambria plant as currently configured averages approximately 5,500 kilovoltampere (kVA). Water consumption at the plant averages approximately 100 gallons per minute (gpm).

The Shade Creek Preparation Plant is designed for 500 tph raw coal feed. Currently the plant is used primarily for t ........
