The Trump administration has included copper, coal, and silver in the list of key mineral resources.

The United States has added uranium, copper, and silver to the government's list of critical minerals, indicating that the Trump administration is expanding the range of commodities it considers crucial to the U.S. economy and national security. According to the government website, the updated list from the U.S. Geological Survey also includes metallurgical coal, potash, rhenium, silicon, and lead. This list is set to replace the 2022 version. The list determines which commodities will be included in the investigation under Section 232 announced by the Trump administration in mid-April regarding processed critical minerals and their derivative products, which could lead to tariffs and trade restrictions. Trump has made strengthening domestic supply of critical minerals a priority, citing the threat to national security, infrastructure development, and technological innovation posed by excessive reliance on foreign supply.
