Copper: the Essential Critical Mineral Powering Our Economy

What Makes a Mineral "Critical" in Today's Economy?

Critical minerals are defined by their essential role in economic and national security, vulnerability to supply disruptions, and importance in manufacturing and technology sectors. These resources are designated as "critical" when their absence would significantly impact a country's economy or defense capabilities.

For a mineral to qualify as critical, it typically must meet several key criteria:

• Essential to key industries – Irreplaceable in strategic sectors like defense, energy, and technology

• Supply chain vulnerability – Limited production sources, geopolitical risks, or processing constraints

• Limited substitutability – Few or no viable alternatives with similar performance characteristics

• Growing demand trajectory – Increasing importance in emerging technologies and green transition

Copper has historically occupied a unique position—universally recognized as essential but often not officially designated as "critical" on national strategic mineral lists. This status has begun to change as governments reassess copper as critical mineral in light of energy transition demands and evolving supply-demand dynamics.

How Does Copper Meet the Definition of a Critical Mineral?
