About this time a small stamp mill, or pounding mill, was built near the mine to crush the gold ore; this was probably the first mill of this type to be erected in the United States.

This means that accessing about 90,000 pounds of ore requires digging and moving between 200,000 and over 1,500,000 pounds of earth—a rough average of more than 500,000 pounds per battery. The precise number will vary for different battery chemistry formulations, and because different regions have widely variable ore grades.
