Will the Black Butte Copper Project lower the water table of the area?

Our numeric hydrologic model shows that dewatering of the mine area will have an effect on the water table only in the area of the mine itself with noticeable drawdown only in the part of the bedrock hydrologic system containing the mine. Continuously backfilling the mine with cemented tailings reduces the extent of drawdown as mining advances. The water table will return to normal on completion of mining.
