Summary of the U.S. Geological Survey's Methodology and Technical Input for the 2025 U.S. List of Critical Minerals Industry Overview - The report focuses on the mineral commodities critical to the U.S. economy, assessing the potential effects of supply chain disruptions on the U.S. economy, particularly in light of the Energy Act of 2020 [16][20]. Core Findings and Arguments - The analysis evaluates mineral commodity supply risk using two main criteria: 1. Economic effects assessment quantifying potential impacts of trade disruptions on U.S. GDP. 2. Examination of reliance on a sole domestic producer, which represents a single point of failure [16][23]. - The study assessed over 1,200 scenarios for 84 mineral commodities, revealing that disruptions could lead to a net decrease in U.S. GDP ranging from nearly $4.5 billion to an increase of $33 million, reflecting U.S. import dependency and global production concentration [16][22]. - Six mineral commodities were recommended for inclusion on the List of Critical Minerals (LCM) based on their risk assessment: - Potash - Silicon - Copper - Silver - Rhenium - Lead Two commodities, arsenic and tellurium, were recommended for removal from the LCM [17][16]. Important but Overlooked Content - The report highlights the increasing risks associated with foreign supply disruptions, particularly due to recent export controls from China on several minerals, including antimony, gallium, and germanium [19][20]. - The methodology used in this assessment represents a significant advancement over previous assessments by incorporating an economic effects model that allows for direct comparison against other economic risks and costs of risk mitigation strategies [17][22]. - The report emphasizes the importance of reliable supplies of mineral commodities for maintaining and growing the U.S. economy, given their essential role in various technologies and industries [19][20]. Conclusion - The findings underscore the critical nature of certain mineral commodities to U.S. economic security and the need for ongoing assessment and strategic planning to mitigate risks associated with supply chain disruptions [16][17].
