How much water will be pump from the mine?

Estimated dewatering rates pumped from the mine range from 220 gpm to 500 gpm as the mine access is developed. The dewatering rate during full operation is estimated between 420 and 470 gpm. All but the 210 gpm of water needed for use in the milling process returns back to the groundwater system via the underground infiltration system after treatment by the reverse osmosis water treatment system.
