The primary coal-bearing formations on these properties are situated in the Central Appalachia portion of the Appalachian Plateau structural province. The coal-bearing formations are Carboniferous in age, being in the Pennsylvanian system which includes the base of the Conemaugh Formation, occurring near the ridge tops in the northern portion of the Leaseco Property; the Allegheny Formation; the upper section of the Kanawha Formation, which comprises the major portions of the exposed ridges; and the New River Formation, which is present below drainage. Surface and shallow subsurface strata consist of fine to coarse-grained sandstones, siltstones, shales, coals, and underclays of the Allegheny Series and Kanawha Group of Pennsylvanian age. The upper approximately three-fourths of the section appear typical of an upper deltaic plane-alluvial plane sequence, heavily dominated by sandstone, and coal seams in this part of the section are generally erratic and subject to rapid changes in thickness and character. The lower approximately one-fourth of the section appears representative of a transitional or lower deltaic plane environment, with siltstone and shale lithologies more prevalent, and coal seams in general exhibiting better regularity and consistency than those in the upper part of the section. The sediments of the Allegheny, Kanawha, and New River Formations were deposited in a northeast-southwest trending and rapidly subsiding basin in western Virginia, southern West V ........

The complex includes the Maple Eagle No. 1 underground mine, the Sycamore surface mine, a preparation plant and other related assets.

Mining Method: Surface/underground/room and pillar

Production Equipment: Continuous miner units and front-end loaders

The Maple underground coal mine operates in the Eagle coal seam and employs the room-and-pillar mining method with continuous miners to produce premium high volatile coking coal, which can be used in the steelmaking process.

All of the underground mining reserves can be accessed by drift entries from the Armstrong Creek watershed.
