Copper and Potash Proposed for Critical Status by USGS

Copper and potash are among six new proposed additions to the US Geological Survey’s latest list of critical minerals — a further step in clearing the way for broader policy support.

The two commodities join lead, rhenium, silicon and silver as additions to the 2025 draft list of 54 critical minerals, according to a Federal Register notice seeking public comment. The USGS also said it intends to analyze the potential for including uranium and metallurgical coal. Arsenic and tellurium are recommended for removal.
