Additionally, reserve projections often underestimate the contents of the earth's crust because lower ore grade deposits may not be considered a reserve (World Nuclear Association, 2012). Demand for elements varies by element group (see Table 1) and the variety of strategic elements results in a similar variety of supply problems.
Copper is vital to modern life and has an often-irreplaceable role in everyday infrastructure and technology. However, while the planet’s Cu endowment is finite, global Cu production continued to increase over the past century—a growth that has been matched by significant growth in estimated Cu mineral reserves and mineral resources.
