Using the government studies cited in American Resources’ Critical Metals Report, we attempt to reconcile conflicting mineral lists and department definitions. We believe the American Resources “Risk Pyramid” provides a reasonable window into the federal government’s approach to the United States’ mineral supply issues.
Until the U.S. Government issues a single and definitive study of critical metals issues in the context of defense and national security, the American Resource Risk Pyramid allows a composite view of the various studies that have been done, and a relative ranking of metals and minerals identified as critical and strategic.
For more information about our methodology, please refer to pages 11-12 of our Critical Metals Report.
