Copper, the most critical metal | Kitco News
· Over 200 copper mines are expected to run out of ore before 2035, with not enough new mines in the pipeline to take their place. Some of the largest copper mines are seeing their reserves dwindle; they are having to dramatically slow production due to major capital-intensive projects to move operations from open pit to underground.

Locations of Deposits
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.
