    In the mine's first years, 4.1 million tons of waste rock will be stockpiled on the surface while the mine is hollowed out. The sulfide-bearing ore deemed to be economically valuable is crushed to increase surface area and then sent to a surface stockpile before entering the concentrator plant where the metals are chemically extracted.
