The Geology of Urgency: Mongolia's Rare Earth Promise and the Race to Build Supply Chains Beyond China

Introduction

In April 2025, China's Ministry of Commerce introduced export licensing requirements for seven rare earth elements and permanent magnet materials — a move widely understood as retaliation for the Trump administration's Liberation Day tariffs. By October, Beijing had expanded those controls dramatically, adding five additional elements, extending extraterritorial jurisdiction to products manufactured outside China using Chinese technologies, and imposing presumptive license denials for any entity with affiliation to a foreign military. According to the IEA's Global Critical Minerals Outlook 2025, China is the leading refiner for 19 out of 20 important strategic minerals, with an average processing market share of 70 percent. In rare earth refining specifically, Chinese state-backed monopolies control roughly 89 percent of global capacity.

The disruption that followed was not theoretical. Western manufacturers scrambled for permanent magnets, automotive factory utilization rates fell, and European rare earth prices reached multiples of their Chinese equivalents. The crisis made concrete what analysts had long argued in policy journals: supply chains built on a single dominant jurisdiction can be interdicted at will. The two strategic responses that have since gained traction — China-independent processing infrastructure in North America and the accelerated development of frontier deposits in Mongolia — are not competing approaches. They are structurally interdependent, and together they define the contours of the post-monopoly rare earth market that Western governments are now racing to construct.

A Control Regime That Keeps Expanding

The architecture of China's 2025 export control escalation deserves careful reading, because its ambition extends well beyond raw material flows. The October 9 announcements from MOFCOM — Announcement No. 61 and its companion notifications — represented the first time China applied a foreign direct product rule to its own export control regime, asserting jurisdiction over foreign-produced items if they contain Chinese-origin rare earths above a 0.1 percent value threshold or are manufactured using Chinese rare earth technologies. The inclusion of rare earth processing equipment and manufacturing technology in the October package was particularly consequential: as the IEA noted, these restrictions on processing equipment risk constraining the ability of emerging projects to refine raw materials and produce permanent magnets, introducing major operational hurdles for nascent industrial ecosystems.

A temporary reprieve arrived in November, when China suspended the October controls for one year following the Xi-Trump meeting, as part of a broader trade agreement. But the suspension applied only to the October announcements, not the April licensing regime, which remains in force and continues to require case-by-case export approvals for seven rare earth elements and permanent magnet materials. The pattern is instructive: each round of controls has been broader than the last, and diplomatic pauses have consistently proved shorter than the investment cycles they were meant to stabilize. As the Foundation for Defense of Democracies observed, Beijing has retained every lever of control it deployed, while reserving the right to escalate further. The supply chain vulnerability is structural, not episodic.

Processing Independence: The North American Infrastructure Bet

The U.S. policy response has been both rapid and revealing about where the critical bottleneck lies. In July 2025, the Department of Defense invested $400 million in equity into MP Materials, making the U.S. government the company's largest shareholder. The deal included a 10-year price floor commitment of $110 per kilogram for neodymium-praseodymium products — approximately $50 per kilogram above spot price at the time — and an additional $150 million loan to expand heavy rare earth separation capabilities at Mountain Pass, California. The Department of War also entered a 10-year offtake agreement for 100 percent of output from MP Materials' planned second magnet manufacturing facility. The message embedded in those terms is clear: Washington is prepared to underwrite the economics of domestic processing at a level that the market alone would not justify.

In Canada, the Saskatchewan Research Council has built a Rare Earth Processing Facility in Saskatoon designed from inception to operate without any reliance on Chinese technology, equipment, or critical consumables — a design constraint that reflects the lesson learned when China banned the export of rare earth extraction and separation technologies in December 2023. At full capacity, the facility is expected to produce approximately 525 tonnes per year of neodymium-praseodymium metal, along with heavy rare earth oxides including dysprosium and terbium. These facilities represent a genuine shift in Western processing capability. But they share a common vulnerability: both require a sustained feedstock pipeline that does not originate in, or route through, Chinese-controlled supply chains. That is precisely where Mongolia enters the analysis.

Mongolia's Geological Endowment and Its Structural Constraints

Mongolia's rare earth potential is rooted in geology that mirrors some of the world's most productive deposits. The country shares alkaline intrusive geological structures with northern China, where the Bayan Obo deposit — the largest known rare earth deposit globally — sits just across the border in Inner Mongolia. Academic research has identified at least twelve sites of significant rare earth mineralization across Mongolia, with three demonstrating established economic potential: the Khalzan Buregtei peralkaline granite deposit in the northwest, and the Mushgai Khudag and Khotgor carbonatite deposits in the south.

Of these, Khalzan Buregtei is the most advanced and strategically significant. The deposit is considered the most important in Mongolia because it is enriched in heavy rare earth elements — the precise category for which Chinese dominance is deepest and Western alternatives most scarce. Dysprosium, the critical input in advanced permanent magnets for electric vehicles and defense systems, is the primary commercial target. In July 2025, Wood Plc was appointed by the Mongolian National Rare Earth Corporation to lead a definitive feasibility study covering both concentrator and refinery process plants, building on a pre-feasibility study completed in 2024. MNREC CEO Tsolmon Adiya has framed the project as one that will contribute to supply chains outside China — an explicit positioning that aligns with Western procurement priorities.

The structural obstacles, however, are equally well-documented. Mongolia sends 84 percent of its exports to China and currently ships 88 percent of its minerals unprocessed. Only 30 percent of the country's territory has been geologically surveyed, and just 1 percent is licensed for exploration — figures that indicate vast upside but also underdetermined resource definition. The Rio Tinto dispute over Oyu Tolgoi, resolved only in 2022 after years of renegotiation, remains the reference case for what investor confidence looks like when fiscal terms are contested. Foreign capital will require greater regulatory predictability than Mongolia's mining sector has historically offered before long-term offtake commitments can be secured.

The Policy Architecture: Western Capital and the Frontier Opening

Western governments have begun constructing the policy scaffolding needed to connect frontier deposits to non-Chinese processing infrastructure. The European Union's Critical Raw Materials Act has set an explicit target of reducing Chinese rare earth dependence by up to 50 percent by 2029, and the EU has committed €3 billion for short-term strategic projects. According to Bloomberg Intelligence's Rare Earths 2026 Outlook, global public funding injections for rare earth supply chain development are expected to reach $10 billion in 2026 alone. The EU has designated 60 Strategic Projects targeting critical minerals, with 13 located in external partner countries including Canada, Kazakhstan, Ukraine, and Zambia — though Mongolia is notably absent from that list, reflecting unresolved institutional gaps that the Khalzan Buregtei feasibility process must address to qualify.

Mongolia's own analysis, published by the Mineral Resources and Petroleum Authority, frames the country's rare earth projects not primarily as fiscal revenue sources but as a strategic bridge to global high-value supply chains. The Mongolian Mining Journal, citing Wood Mackenzie's year-end 2025 report, noted that rare earth elements have become what analysts describe as "the most powerful weapon in modern diplomacy." If Khalzan Buregtei and the Khotgor project reach full production, Mongolia plans to supply between 552,800 and 903,000 tonnes of REE concentrate annually to international markets. At those volumes, the country would represent a material addition to the non-Chinese feedstock base — particularly in heavy rare earths — that facilities like Saskatchewan's separation plant are designed to process.

Conclusion

The 2025 rare earth export controls have served an unintended clarifying function. They have demonstrated, with factory-floor consequences, that supply chains built on a single dominant refiner can be interdicted at will and that diplomatic truces offer only temporary insulation. The structural response — North American processing infrastructure designed for Chinese independence, and frontier geology in Mongolia being advanced toward production — reflects a coherent logic: processing capacity without diverse upstream supply is fragile, and geological endowment without processing independence is commercially inert. Only the combination constitutes genuine resilience.

Mongolia's Khalzan Buregtei deposit, now advancing through definitive feasibility with Wood Plc as lead consultant, occupies a precise position in this architecture. Its heavy rare earth content, led by dysprosium, addresses the segment of the supply chain where Chinese dominance is most acute and Western alternatives most scarce. What remains unresolved is the institutional scaffolding — stable fiscal terms, offtake agreements, development financing — that would formally connect Ulaanbaatar's geology to Saskatoon's separation capacity. The geological case has been made. The geopolitical case is being made by Beijing with every new export control announcement. The remaining question is whether Mongolia's regulatory environment, and the Western capitals now deploying rare earth capital at scale, can move from strategic intention to commercial execution before the next round of Chinese leverage resets the terms of engagement.
