“The United States has consistently maintained that a strong domestic minerals and metals industry is an essential contributor to the nation’s economic and security interests…The United States has a fundamental interest in maintaining a competitive minerals and metals sector that will continue to contribute significantly to the nation’s economic strength and military security. The industry represents an $87 billion enterprise that employs over 500,000 U.S. workers and provides the material foundation for U.S. manufacturing.” The 1980 National Academy of Sciences executive summary of “Competitiveness of the U.S. Minerals and Metals Industry”
A concise summary of U.S. mineral vulnerabilities was presented to the Industrial Readiness Panel of the House Armed Services Committee as early as 1980 by General Alton D. Slay, Commander Air Force Systems Command. He pointed out that technological advances have increased the demand for exotic minerals at the same time that legislative and regulatory restrictions have been imposed on the U.S. mining industry.
The 1981 report “A Congressional Handbook on U.S. Minerals Dependency/Vulnerability” singled out eight materials “for which the industrial health and defense of the United States is most vulnerable to potential supply disruptions” – chromium, cobalt, manganese, the platinum group of metals, titanium, bauxite/aluminum, columbium, and tantalum – the first five have been called “the metallurgical Achilles’ heel of our civilization.”
