Upgrade of processing facility

The Willow Creek Prep Plant was constructed as a 450 tph partial wash facility for upgrading coarse metallurgical coal (+12.7 mm) for the PCI market. The original preparation plant included a small fine coal cleaning circuit to process misplaced fines that report to the wash plant. The 12.7 mm x 0 fine raw coal reported directly to the product stream. Due to decreasing fine raw coal quality within the existing mineable seams, DRA Global was contracted to upgrade the facility to process 660 tph of 50 mm x 0 metallurgical coal.
