In February 2021, the United States Bankruptcy Court for the Western District of Kentucky confirmed Hartshorne’s plan of liquidation. In February 2021, the plan of liquidation became effective, and Hartshorne commenced the final stages of winding up the estates.
Hartshorne executed a liquidation trust agreement and transferred its remaining assets and liabilities to a liquidation trust, as well as assigning remaining critical contracts and insurance policies. Hartshorne funded the carve-out escrow with the majority of Hartshorne’s cash-on-hand and transferred any remaining cash to the liquidation trust. The Hartshorne entities were dissolved on the effective date. The remaining assets will be liquidated by the trustee over time.

Summary:
The Buck Creek Mining Complex of Cypress (Buck Creek No.2 Mine) coal resource is in the WK No. 9 coal seam approximately 650 feet below the surface at the proposed mine portal site. The coal seam is flat lying with a modest dip of 2 to 3 degrees generally to the northwest and toward the centre of the bowl-shaped Illinois Coal Basin. Thickness of the WK No. 9 coal seam modelled in the CRE averages approximately 3.8 feet (46 inches), a suitable seam thickness for high- productivity underground mining with approximately 0.7 feet (8 inches) of out-of-seam mining needed to achieve an average mining height of 4.5 feet (54 inches) required for equipment clearance. Seam and mining heights are similar to a number of underground mines in the region.
Mining Methods
- Continuous
- Room-and-pillar
Summary:
The Cypress is a well-defined coal resource, which is located in an area with a long history of coal mining. Proposed production from the mine will come exclusively from utilising the room-and-pillar method. The selection of underground room-and-pillar mining is validated by examining the method of mining used by adjacent operations which are some of the highest productivity room-and-pillar mines in the world.
In addition, the room-and-pillar mining method with continuous miners has received all of the necessary approvals from regulatory agencies at nearby operations and is supported by well-established equipment models with a ready supply of repair and replacement parts. No prototype equipment has been selected for use in the Cypress.
The slope is designed as an 18-foot wide by 18- foot high slope constructed at a 16 degree gradient that measures approximately 2,500 feet in length from the bottom of the box cut to the coal seam. This length includes an allowance for a vertical curve at the bottom of the slope to provide room for a level segment of the slope belt for conveyor transfer points.
A dual-compartment vertical airshaft will be constructed in order to ventilate the mine. One-half of the shaft will be designed for intake (fresh) air, and the other will carry return air which has coursed through the mine. The shaft will be constructed on the permitted surface site by conventional drilling, blasting and mucking from the surface to a dept ........
