Now think to yourself how far it extends depth-wise. The fact that there's workings there tells ya something.
Bingham Canyon is 4km wide and 1km deep. It's a porphyry copper deposit, grading 0.47% copper, 0.25g/t gold, formed by a quartz monzonite porphyry intrusion. It also happens to be the largest man-made excavation in the world (for the time being).
