Highlights

• The Strategic Defense Critical Mineral Factbook 2025 highlights that China's dominance in minerals stems from its refining capacity, not geological reserves.
• China controls the processing of antimony, gallium, germanium, graphite, and tungsten, despite mining activities being distributed globally.
• The report indicates that U.S. mineral vulnerability is primarily a processing issue.
• Lack of domestic or allied refining capacity means new mines and friend-shoring strategies cannot fully address strategic supply chain exposure.
• Known risks are quantified in the report, but it does not provide execution roadmaps.
• Rebuilding processing infrastructure remains a critical unresolved challenge for U.S. mineral security.

The newly released Strategic Defense Critical Mineral Factbook 2025 (opens in a new tab) by Andrew Knipe of the Silverado Policy Accelerator delivers a sober, data-driven diagnosis of America’s most acute mineral vulnerabilities—and in doing so, quietly reinforces a reality Rare Earth Exchanges™ has tracked since our launch last year:

China’s dominance in critical minerals is not primarily geological, but industrial and processing-based. Drawing on U.S. Geological Survey data, refinery capacity estimates, and trade-exposure analysis, the Factbook identifies a class of “Strategic Defense Critical Minerals” where U.S. national security faces direct and concentrated risk from foreign entities of concern—chief among them, China.

Where the Numbers Stop—and the Pattern Emerges

The Factbook’s charts are stark. Across antimony, gallium, germanium, graphite, rare earth elements, tungsten, and tantalum, China controls a dominant share of global refining and processing capacity, often far exceeding its share of mine production or reserves. In rare earths, the asymmetry is especially pronounced: while mining is geographically distributed, downstream refining and magnet-grade separation remain overwhelmingly concentrated in China, particularly for heavy rare earths and magnet materials. Similar patterns appear in gallium, germanium, and battery-grade graphite—materials essential to semiconductors, defense systems, EVs, and advanced electronics.

What the report gets right is precision. It clearly distinguishes between mine production, reserves, and refinery output, exposing where the U.S. vulnerability truly lies. In many cases, America’s weakness is not a lack of ore in the ground, but a lack of domestic or allied processing capacity.

What the Factbook Doesn’t Say—But Shows

The Factbook avoids polemic language, but its implications are unmistakable. Even where mining is geographically diversified—graphite in Africa, rare earths in Australia, tantalum in the DRC—processing chokepoints re-centralize control in China. This explains why export controls on gallium, germanium, or rare earths ripple immediately through Western defense and technology supply chains, while new mines take a decade or more to materially affect supply.

There is little speculation here; if anything, the bias is institutional conservatism. The report catalogs risk without prescribing urgency. Yet the data quietly undermine any narrative that upstream “friend-shoring” alone can solve strategic exposure.

Why This Matters for the Rare Earth Supply Chain

For investors and policymakers, the takeaway is structural: rare earth and critical mineral security is a processing problem first, and a mining problem second. The Factbook’s own tables show that without refining, reserves are strategic illusions. This aligns with REEx reporting—China’s advantage rests on decades of industrial integration, permissive permitting, and state-backed scaling, conditions the U.S. has yet to replicate.

Limits and Open Questions

The Factbook is intentionally narrow. It does not model timelines, capital costs, environmental trade-offs, or workforce constraints involved in rebuilding processing capacity. Nor does it assess whether U.S. allies can realistically substitute Chinese refining at scale. These omissions are not errors—but they matter for execution.

REEx Conclusion

The Strategic Defense Critical Mineral Factbook 2025 is accurate, rigorous, and quietly damning. It confirms that America’s mineral vulnerability is known, mapped, and quantified. What remains unresolved is action. The current administration has at least introduced some urgency, but not nearly sufficient industrial policy. Until processing capacity is rebuilt—domestically or with trusted partners—control will continue to flow to those who refine, not those who mine.
