Comparison of Changing Estimates for Copper

Caption

Comparison of changing estimates for copper reserves, resources and theoretical estimate of ultimate resource to depth of 3.3 km. These estimates are based on grades similar to those of deposits exploited today. If lower grades become feasible to mine, as has occurred over the past century, the resource size could increase significantly. Note log scale.
