Deposit Type

  • Sedimentary


Summary:

The Property is situated in the southern portion of the Appalachian Basin, which contains two-fifths of the nations’ bituminous coal deposits and extends over 900 miles from northern Alabama to Pennsylvania.

The primary coal-bearing formations on the Property are Carboniferous in age, being in the Pennsylvanian system, which includes the Breathitt Formation. The average mineable seam thickness for coal horizons in these formations ranges from 1 foot to over 6 feet. The coal seams are generally continuous and non-complex but may vary in thickness and may also be locally absent. Seams retain normal stratigraphic sequence throughout the Property and no evidence has been observed that seams have been modified from pre-deformational thicknesses.

Mineable coal seams within the Property are typically low-ash with the exception of the Joyner seam, and highthermal content bituminous coals. The maximum seam thic ness may reach over 6.0 feet in the Upper Jellico underground mines; however, the average mineable thickness of the seams in this evaluation generally ranges from 1 foot to 4 feet. Seams are generally continuous, but may be locally absent. Secondary discontinuity due to erosional features is present in most areas, resulting in seam outcropping, or visible exposure of the seam at the surface. Other than oxidation of the coal exposed at the surface, erosion of the seams has no significant impact on the mineralized deposits. All seams outcrop on the property ........

Summary:

The Cumberland Gap mine is a projected future underground mine. There is currently no active underground mining in the Cumberland Gap seam.

The Cumberland Gap (Straight Creek) mine is located on Straight Creek. The Cumberland Gap seam is accessed via slope and shaft. Cumberland Gap is a thermal coal mine and is located on the WPP lease.

Production is scheduled for 255 days each year, which represents production on Monday through Friday and occasional Saturdays with idle holidays. On each day, three production sections are scheduled to produce coal on two shifts; the third shift is reserved for maintenance and mine conveyor belt and power moves. The sections are configured with one continuous miner available in each for production. One section, which will be used for developing mains, will be a conventional section, using shuttle cars to transport coal from the continuous miner to the conveyor belts. The other two sections will employ continuous haulage equipment to transport coal from the continuous miner to the conveyor belts. Productivity is planned at the rate of 220 feet of advance for each unit-shift of operation in the conventional section and 340 feet of advance for each unit-shift of operation in the continuous haulage sections. A total of 46 to 129 employees are assigned to the mine.

Principal production equipment includes a continuous miner, two roof bolters, two scoops, and either three shuttle cars or three bridge conveyors and t ........
