Copper: Officially a US Critical Mineral
Given the key role copper plays in the energy transition and uncertainty surrounding its future supply, it would be safe to call the red-colored metal a “critical mineral”. Yet in the United States, that hasn’t been the case, at least until recently.
According to the US Geological Survey, a “critical mineral” must meet the following three criteria: 1) It is essential to economic and national security; 2) It plays a key role in energy technology, defense, consumer electronics, and other applications; and 3) Its supply chain is vulnerable to disruption.
While copper qualitatively does satisfy all of those, quantitatively though, its risk score has been below what the USGS uses as a cut-off, rendering it somewhat of a “pseudo critical mineral”.
But that all changed on July 31, 2023, when the US Department of Energy (DOE) officially put copper on its critical materials list, marking the first time a US government agency has included copper in a “critical” list, following the examples set by the EU, China, Canada, and many other major economies.
Also included in the DOE’s list are aluminum, cobalt, copper, dysprosium, electrical steel, fluorine, gallium, iridium, lithium, magnesium, natural graphite, neodymium, nickel, platinum, praseodymium, terbium, silicon, and silicon carbide.
