The relatively concentrated portion of this copper is only a small fraction of the whole, constituting an estimated 10 10 metric tons in deposits with a grade of 0.25% or more. At current world mine production, this represents a million years' supply of copper theoretically available in the mineable portion of the earth's crust.
