The Leer Mine reserve is a relatively flat lying, sedimentary deposit of Pennsylvanian Age. The Leer Mine is actively mining a single coal seam, the Lower Kittanning.The principal minable coal seam on the Leer Mine Property is the Lower Kittanning Seam. The Lower Kittanning Seam occurs in a larger area, with a higher seam thickness than all other listed seams in the formation. The Leer Mine is actively mining the Lower Kittanning Seam. The Lower Kittanning Seam reserve extends northeast from Grafton, West Virginia toward Thornton, West Virginia. The reserve area is approximately 6.5 miles in length and approximately 4.0 miles wide. The Lower Kittanning Seam consists primarily of a single horizon of coal with a bone coal parting. Drillholes show seam thickness ranging from 0.0 to 10.5 feet. The seam thins (< 3.0 feet) to the south and east of the Leer Mine LOM Plan and to the north and east of the northern extension of the Leer Mine LOM Plan. The mineable coal seam is typically low-ash, high thermal content, high volatile A rank bituminous metallurgical coal product. Parting does occur within the property and generally is between one and three feet thick. The parting does not affect the end product since the coal is washed. The seam is generally continuous but is absent in areas outside the Leer Mine LOM Plan. These sub-crops of the Lower Kittanning seam are usually from sandstone washouts.
