The Pentagon is reconsidering an $80 million conditional loan to rare-earths refiner ReElement Technologies, according to reports, creating a public dispute with White House officials. The loan was announced in November by the Pentagon’s Office of Strategic Capital (OSC) as part of a broader U.S. push to build domestic critical-minerals supply chains and reduce reliance on China. No money has been disbursed, and the government says the deal remains subject to financial, legal and technical due diligence.

Officials reviewing the proposal raise doubts about whether ReElement can scale production and reach stated long-term revenue targets. The disagreement reflects an internal tension between moving quickly to develop rare-earth capacity and applying rigorous vetting for emerging companies. White House trade adviser Peter Navarro has criticized OSC’s review process as overly burdensome, describing the company as the type of high-risk investment the administration wants to pursue.

Bloomberg reports that Pentagon representatives defend OSC’s oversight, saying it seeks both speed and disciplined dealmaking. ReElement’s chief executive says the company is continuing its work and its Indiana refining facility development. Under the arrangement, ReElement would produce rare-earth oxides from recycled materials, while partner Vulcan Elements would convert them into magnets for defense and energy uses.
