The coal reserves reported herein are typically high-volatile bituminous coals with the exception of the Kittanning A, B, C, D and Eagle horizons, which exhibit some mid-volatile characteristics. The primary coal-bearing formations on these properties are Carboniferous in age, being in the Pennsylvanian system, which includes the base of the Conemaugh Formation; the Allegheny Formation; the Kanawha Formation; and the New River Formation. The average mineable seam thickness for coal horizons in these formations ranges from 2.5 to 6.0 feet, with the exception of the Peerless seam at Leaseco where the minimum is 2.25 feet. Within the subject properties coal zones can locally exceed 9.8 feet where individual coal beds merge to form a single mineable unit. Structurally, the strata on the subject Property exhibit a regional northeast southwest strike and a regional northwestward dip of approximately one to four percent, averaging about three percent and are flat-lying. The seams are generally continuous and non-complex but may vary in thickness and even locally be absent. Furthermore, the seams are unaffected by tectonic deformation.

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.
