Summary:
The Oaktown Mining Complex is situated in the Carbondale Group (Formation) of the Pennsylvania System. Near-surface geology of this area primarily consists of the overlying Quarternary System. Coal seams mined in this region are generally classified as medium- to high-sulfur content and moderate ash thermal coal products.
The Indiana V Seam is the only coal seam of economic interest on the property. Structurally, the Indiana V Seam consists of a singular and relatively consistent horizon averaging between 4 ft to 8 ft thick containing little in-seam parting. The Indiana V globally dips in the general westerly direction and experiences localized areas where the seam elevations vary. Pronounced gradients can occur periodically in the form of rolls in the seam. Depths for the Indiana V Seam range from approximately 300 ft to 450 ft below ground surface within the Oaktown Mining Complex area.
The Indiana V Seam coal bed is characterized as high sulfur and moderate ash coal that is used for steam purposes.
Pennsylvanian sedimentary strata comprise the uppermost stratigraphic units of bedrock in and around the Oaktown Mining Complex. These units primarily include bedrock of, in descending stratigraphic order, the McLeansboro, Carbondale and Racoon Creek Group. The strata of the Pennsylvanian system are predominantly clastic and contain subordinate amounts of coal and limestone. The Indiana V (Springfield) coal seam resides within the Carbondale Grou ........

Summary:
The Oaktown Mining Complex is comprised of the Oaktown Fuels No. 1 and Oaktown Fuels No. 2 underground mines. Each mine utilizes R&P mining (employing continuous miners [CMs]) for primary production. This mining method is highly productive and commercially demonstrated; it has been one of the primary approaches to mining the Indiana V Seam for decades. Oaktown Mining Complex has utilized this mining method since the inception of each operation. To date, Oaktown Mining Complex has produced a combined 58.3 million tons of clean coal. The complex is configured to operate up to seven CM sections, with an annual production target of approximately 8 million product tons. The Oaktown Mining Complex is generally considered an industry leader in terms of mining productivity and mining costs when compared to other R&P underground operations.
The Oaktown Mining Complex LOM plans developed by BOYD show a relatively stable production output until individual production sections are retired corresponding to reserve exhaustion. In the aggregate, the Oaktown Mining Complex LOM plan projects the complex will produce approximately 131.6 million tons of run-of-mine (ROM) coal (91.6 million saleable tons after processing) during the next 17 years (through 2038).
Coal is produced by the Oaktown Fuels No. 1 and No. 2 underground mines using the R&P mining method. R&P mining is a partial extraction technique that recovers a portion of a coal seam.
