The $58 million mineral bet and the much harder problem behind it

THE UNITED States' answer to China's stranglehold on critical minerals this week takes the form of three small loans. On 7 August the Export-Import Bank announced $58 million in financing for projects that will produce graphite in Alabama, process tantalum and niobium in Pennsylvania and boost boron output in California. It is the sort of announcement that looks decisive on a press release and almost nothing at all on a balance-sheet.

The trouble with the critical-minerals story is not the rhetoric, which has been consistent across administrations for years. It is the arithmetic. China refines approximately 70% of global production across 19 of the 20 strategic minerals analysed by the International Energy Agency. For graphite, the material that makes lithium-ion batteries work, China accounts for 96% of refined output, according to IEA and World Economic Forum data. For tantalum, used in the capacitors of smartphones and automobiles, it holds 46% of global refining. The United States does not mine tantalum or niobium at all; it imports nearly all of its boron, a mineral the government only added to its critical list last year.

These three ExIm loans are directed at that gap. Westwater Resources receives $25 million for a graphite mine and processing plant in Alabama — the country's first source of natural graphite, though the firm has been developing the project since 2021, when its board approved $202 million for phase one. Global Advanced Metals, another $25 million recipient, mines tantalum and niobium in Australia but processes them in Pennsylvania; the US currently relies on foreign supply for both metals. The remaining $8 million goes to 5E Advanced Materials for a boron project in California, with commercial production expected in 2028.

The loans are real. The problem is whether they are enough, and whether they are pointed at the right bottleneck.

The reason is not hard to see. China's dominance in critical minerals is not primarily a mining story. It is a processing one. The United States could mine all the graphite it needed tomorrow and still ship it to China for refinement into battery-grade material. The midstream bottleneck — turning ore into something an engineer can use — is where Beijing has built an infrastructure moat that no small number of ExIm loans can quickly fill. Rebuilding refining capacity requires capital investment measured in the hundreds of millions or billions, multi-year construction timelines, and the ability to tolerate environmental and community opposition that American politicians have historically been unwilling to absorb.

To be sure, the $58 million is not the whole of the administration's strategy. ExIm's statutory exposure cap stands at $135 billion, and in February 2026 the bank approved a separate $10 billion direct loan for a Strategic Critical Minerals Reserve. The Department of War has committed hundreds of millions more to midstream rare-earth projects, including a deal with MP Materials in California that combines a $400 million equity stake with a price floor for neodymium-praseodymium oxide. The administration has also used the FAST-41 infrastructure-expediting process to approve several mines and signed an $8.5 billion critical-minerals agreement with Australia.

Yet even the broader picture leaves structural questions unanswered. ExIm's total annual authorizations in fiscal 2025 were $8.7 billion, against a target of $11.3 billion for fiscal 2026. The bank's charter expires on 31 December 2026, pending congressional reauthorisation. The institution is being asked to perform a strategic supply-chain function for which its authorities, risk appetite and tools were never designed. The default-rate ceiling of 2% is fine for commercial export finance. It is arguably too conservative for the kind of patient, early-stage mineral projects that struggle to attract private capital precisely because they are unproven.

The deeper problem is that mining and processing expansion are the slowest possible response to a supply-chain vulnerability. China has been investing in this sector for more than a decade, under state plans that outlasted several US presidential administrations. As the Council on Foreign Relations noted in a February 2026 report, traditional catch-up would take years or decades. The more promising American strategy would involve leapfrogging: materials engineering that reduces or eliminates rare-earth dependence, waste recovery and recycling that creates circular supply chains, and technologies that extract minerals from mine tailings and industrial by-products. Those are the areas where the United States can compete on innovation rather than on the ability to outspend the Chinese state in low-margin refining.

Some of that is already happening. Companies such as Niron Magnetics are scaling rare-earth-free magnets using iron nitride, backed by ARPA-E funding. ReElement Technologies entered a $1.4 billion public-private partnership announced in November 2025, combining government loans with private capital for domestic rare-earth processing. But the scale remains modest, and the "valleys of death" between lab discovery and commercial scale remain under-financed. Debt-based government instruments like ExIm loans are ill-suited to that early-to-growth stage. Equity, patient venture-style capital and risk-sharing mechanisms would fill the gap more effectively.

The three new loans will produce minerals. If they go according to plan, they will also demonstrate that American companies can build processing capacity on home soil. That is valuable in itself. But the political appeal of a press-release announcement should not be confused with supply-chain resilience. The United States is 100% import-reliant for 12 critical minerals and over 50% reliant for 29 more, according to the US Geological Survey. The gap between that reality and three ExIm loans, however useful, is measured in billions of dollars and a generation of investment.

A wiser policy would treat the ExIm financing as one tool among many, not as a strategy in miniature. The first task is to close the financing gap for early-stage mineral technologies that could reduce dependence on Chinese processing, not merely replicate it on American soil. The second is to give ExIm and similar institutions authorities suited to patient, strategic capital, not just short-term commercial lending. The third is to accept that environmental permitting, community opposition and the political costs of mining are not bugs to be legislated away but constraints that any realistic timeline must acknowledge.

China measured its advantage in decades. The United States should measure its response the same way.
