Mine Life | 2031 |
Gibson South mine currently has approximately 23,350 underground acres permitted. The mine property is controlled through both fee ownership and leases of the coal. Leases generally have an initial term with automatic extensions for as long as mining operations are conducted within a described area.
Production from the Gibson South mine is shipped by truck or rail via CSX or NS railroads from a rail unloading point directly to customers or to various transshipment facilities, including the Mount Vernon Transshipment Facility, for delivery by barge. |

Summary:
Gibson South extracts coal underground from the Springfield (Indiana No.5). The seam lies between 450 and 650 feet deep and dips gently (about 1%) to the west/southwest. The seam varies in thickness over the reserve area from over nine feet in the northern areas in close proximity to the Galatia paleochannel and thins to four feet in the south, distal to the channel. The average coal thickness within the GSM is about six feet.
On a 1.50 float, dry basis, the Springfield seam averages about 7.1% ash, 2.0% sulfur, and 13,500 btu/lb. The mineral deposit type (coal rank) mined by the GSM is a high volatile bituminous B/C coal.
The geologic model developed to characterize the resource/reserve is a bedded sedimentary deposit model. This is generally described as a continuous, non-complex, typical cyclothem sequence that follows a bedded sedimentary sequence. The geology, including coal thickness and extent has been and continues to be verified by an extensive drilling program.
