Processing

Summary:

Raw coal is hauled from the mine by truck either directly to customers or to the Levan rail loadout where it is transloaded and shipped by the Union Pacific railroad.

As necessary to meet customer requirements, the company selectively wash a portion of the coal produced from the Sufco mine at 400 ton-per-hour Castle Valley preparation plant (‘Castle Valley Prep Plant’), which is located at the Savage Energy Terminal.

The Levan rail loadout, which is located 82 miles from the Sufco mine, maintains 1.2 million tons of stockpile capacity in three separate stockpiles with blending capabilities to meet customer specifications. The Levan rail loadout is capable of railcar loading at 4,000 tons per hour and has sufficient rail loop siding capacity to accommodate unit trains of 104 railcars.
