Copper is a critical mineral that plays a vital role in the economy and national security. The Copper Development Association (CDA) is a company that advocates for the inclusion of copper on the U.S. Critical Minerals List. The company recognizes the importance of copper in energy technology, defense, consumer electronics, and other applications. With a vulnerable supply chain, copper is susceptible to disruption, making it a critical mineral that requires immediate attention. CDA's main service is to provide data and research on the criticality of copper, which is essential to economic and national security. The company aims to urge the Secretary of Interior to add copper to the Critical Minerals List, ensuring the availability of this essential mineral for the country's defense and economic security.
