Summary:
The properties are located in the Pocahontas Coalfields of the Central Appalachian Coal Basin. The Carboniferous age coal deposits are situated in the Pottsville Group, New River and Pocahontas Formations. The rock strata, including the coal deposits, are sedimentary rocks formed by alluvial, fluvial and deltaic sediments deposited in a shallow, subsiding basin. The most common rock types are various types of sandstone and shale, with the coal deposits typically in multiple seams in relatively thin coal beds, one to five feet thick.

Summary:
Princeton is a coal mine in Princeton, West Virginia, that specializes in surface and underground mining of coal to produce coke and pulverized coal injection (PCI).
Princeton's operations consist of three open-pit surface mines, two underground mines, a preparation plant and two rail loadouts.
The property has a long history of coal mining, mostly by predecessors in title to AMP. Significant underground mining of some of the deeper coal seams on the properties have occurred, notably the Pocahontas seams nos. 3 and 4, along with the no. 11 seam. In addition, a substantial amount of the thicker coal outcrops has been contour mined previously, providing access for highwall mining and on-bench storage of excess spoil from future surface mining.
