The coal seams of interest within the Property are the Powellton and Eagle.

Strata on the Property are mostly of the Pennsylvanian-age Kanawha Formation and the older, lower Beckley and Fire Creek seams are part of the New River Formation of the Pottsville Series. The rock formations between the coal seams are characterized by large proportions of sandstone interspersed with shale units.

Coal seams with remaining resource potential evaluated within this TRS include, in descending stratigraphic order, the Powellton and the Eagle seams.

Seam Description
The coal produced at the Power Mountain complex is High-volatile B bituminous coal based on the ASTM classification of coals. This ranking is for coal with greater than 31% volatile matter and a moist, mineral matter free btu of 13,000 to 14,000. These coals have historically been sold on metallurgical market. Due to the high value of these High Volatile coking coals, all the seams have been extensively mined in the past. Generally, the coal rank increases with depth whereas the highest seams stratigraphically and physically on the hills exhibit the greatest volatile matter content. are along the southeastern margin of the resource northwest at approximately 2%. The Eagle seam at Jerry matter conte ........

The complex has one active underground mine - Jerry Fork Eagle Mine (with an estimated life of 3 years) which produces High Vol. B quality met coal from the Eagle coal seam. In November 2022, the Company acquired additional property rights and coal resources and plan to develop a second underground mine which will produce High-Vol. B quality met coal from the Powellton seam with production expected to commence in 2023.
