President Trump is set to convene senior mining executives at the U.S. State Department on Aug. 7, 2026, as the administration pushes to secure critical mineral supplies for the United States and its allies. Earlier reporting identified Rio Tinto, BHP and Freeport-McMoRan among the companies tied to the meeting, with other mining and materials groups also expected. The supply push has gained urgency as the United States works to replenish weapons inventories depleted during fighting with Iran. Reuters previously reported that U.S. stockpiles of precision-guided missiles and air defense interceptors were heavily consumed over more than five months of war, and defense officials and lawmakers warned that replacing some inventories could take years because of limited production capacity, even as the Trump administration denied reports of severe ammunition shortages. Pentagon officials and defense companies have said minerals including rare earths, tungsten, germanium and scandium are essential to producing precision-guided missiles, fighter jets, armored vehicles, infrared sensors and other advanced weapons systems. The meeting also fits into a broader policy effort that includes a $12 billion mineral stockpile initiative announced in February and a July 2026 executive order tightening sourcing rules for defense contractors.
