Mine Life2025
Schrock Run (including the associated Schrock Run Extension area) is an active surface mining area scheduled to be completed in 2024. Schrock Run highwall mining operates in 2023 to 2025.

Saleable product from the surface operations is projected to be sold into both the metallurgical and thermal coal markets.

The Shaffer property is proposed as replacement production upon depletion of the Schrock Run/Schrock Run Extension operations and is scheduled to operate from 2024 to 2026. Will Farm is a proposed surface mining area scheduled to operate from 2026 to 2028.

Summary:

Geology of the Properties The geology of the properties is consistent with regional structural trends. In Maryland, the local Casselman synclinal fold is evident in the Casselman mine. 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, in descending stratigraphic order: Sewickley, Redstone, Pittsburgh, Bakerstown, Upper Freeport, Lower Freeport, Upper Kittanning, Middle Kittanning, Lower Kittanning, Brookville, and Mercer. 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 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 outcro ........

Summary:

Schrock Run (including the associated Schrock Run Extension area) are the only active surface mining area scheduled to be completed in 2024. Expected production for the operations totals approximately 224,000 marketable tons.

Schrock Run highwall mining operates in 2023 to 2025 and mines an additional 200,000 marketable tons.

The Schrock Run Extension mine, a surface mine using contour and highwall mining methods.

The proposed surface mines are planned to be operated by a mobile equipment spread built around Hitachi EX3600 or Komatsu PC 2000 shovels as the principal excavators. The surface mine operations are linked in the financial model by the progression of equipment spreads and crews from resource area to resource area. The configuration of this equipment spread, or fleet is projected to be maintained for the future mine projections. Equipment replacements are scheduled at appropriate times over the period for the equipment.

The Hitachi and Komatsu shovels are supported with a fleet of equipment including:
- Caterpillar 785 Rock Trucks;
- Caterpillar D11 Tractors;
- Caterpillar 16M Road Graders; and
- Other support equipment including backhoes and service trucks.

The mine model generally targeted overburden strip ratio limits of 16 to 20 bcy of overburden per ton. Higher ratios may be encountered occasionally. Tractor contribution to production may drop due to shorter panel lengths and rock truck ........


Crushing and Grinding

Corsa preparation facilities have raw coal handling systems consisting of a rotary breaker and screen used to remove large rock and size raw coal.

Production:
Roughly 50% of the proposed production planned for the thermal market is assumed to be washed, while the remainder of the thermal coal product is assumed to be shipped raw to customers.
