Why One-off Federal Investments Won’t Make or Break US Critical Mineral Supply

To understand how these interventions are perceived across the critical minerals sector, we interviewed industry experts, academics, and company representatives on how new policy approaches could impact supply chain dynamics.

Experts broadly agreed on the project-finance challenges facing mining and minerals processing, with investors discouraged by systemic uncertainty over payback periods and long-term mineral demand. Most experts agreed that US interventions like price floors, offtake agreements, and equity stakes are likely to continue in an environment of volatile and depressed prices, even though these policies can be extremely expensive for the government. We also observed consensus among experts that stable downstream market demand is crucial for offtake agreements and price-stabilization efforts to succeed.

While interviewees generally viewed the deal with MP Materials as a national security priority and therefore a necessity, the deals struck with other projects—such as Lithium Americas, Trilogy Metals, and Vulcan Elements—prompted more questions. Some voiced concern over whether the decisionmaking was based on robust techno-economic and environmental impact analyses, if a compromise was struck on investing in more strategic projects in favor of immediate solutions, and the connections between the administration and selected projects.

Experts also agreed on the need for bilateral and multilateral international agreements, especially with allies like Australia and Canada, as the United States has limited mineral-processing capabilities. Despite consensus on the need for such frameworks, some emphasized that international deals must not act as substitutes for supporting domestic processing capacity in limited cases.

Several experts noted the need to strengthen federal technical capacity and argued for reviving the functions that once were carried out by the US Bureau of Mines, or creating a modern counterpart, noting that continued federal intervention without such technical expertise could lead to inefficiencies in public-private partnerships. However, others cautioned that reviving the bureau might politicize decisionmaking and duplicate the work of existing research arms such as the National Laboratories and the Critical Minerals Innovation Hub.
