This estimate is for reclamation of the entirety of the planned extraction areas (formerly <br /> Tract A, Tracts B, and Mineral Reserve Area 1) from a static water surface elevation with <br /> maximum lateral inflow. The analysis computes the cost to dewater the full pit, and then <br /> to dewater for one additional month while reclamation is completed. <br /> RAPTOR MATERIALS, LLC.
