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

Our numeric hydrologic model shows that any water table changes affect only 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.
