North America rare earth production is concentrated at a handful of operating assets — but government-backed investment and a pipeline of advanced projects are reshaping the region’s position in global supply chains. The United States accounts for roughly 12–14% of global rare earth mine output, almost entirely from MP Materials’ Mountain Pass facility in California. Canada is at an earlier stage but holds significant hard-rock deposits that have attracted both federal funding and strategic offtake interest from allied nations.
North America Rare Earth — Why It Matters Now
China controls approximately 60% of global rare earth mine production and a far higher share of separation and processing capacity — a structural imbalance that has driven US and Canadian policy intervention since at least 2020. China’s imposition of export controls on heavy rare earths including dysprosium and terbium, tightened in 2023 and again in early 2025, has added urgency to supply chain diversification across allied governments.
The US response has combined regulatory and financial tools: the Inflation Reduction Act (IRA) critical minerals provisions, Defence Production Act (DPA) Title III funding, and direct Department of Defence (DoD) grants to domestic producers and processors. Canada’s Critical Minerals Strategy, launched in 2022 and updated in 2024, commits CAD 3.8 billion to critical mineral development, with rare earths among the priority commodities. A bilateral US–Canada critical minerals partnership, formalized in 2023, has accelerated project-level co-operation and cross-border supply agreements.
The strategic logic is straightforward: north america rare earth supply that bypasses Chinese processing reduces exposure to export restrictions and tariff escalation. Both governments are backing projects that can demonstrate near-term production, not just resource definition.
United States Rare Earth — Key Assets and Producers
MP Materials (NYSE: MP) operates Mountain Pass in San Bernardino County, California — the only operating rare earth mine and concentrator in the United States. Mountain Pass produced approximately 45,000 tonnes of rare earth oxide (REO) concentrate in 2024, making it the largest single producing asset outside China by output. MP Materials has expanded into downstream processing, commissioning a separation facility at Mountain Pass and constructing a magnet manufacturing facility in Fort Worth, Texas, targeting NdFeB magnet production for General Motors.
Energy Fuels (NYSE American: UUUU) operates the White Mesa Mill in Utah — the only fully licensed conventional uranium and rare earth processing mill in the United States. Energy Fuels has been expanding its REE processing capability, receiving rare earth carbonate from Chemours’ monazite operations in Georgia and from international sources including Brazil. White Mesa is positioned as a midstream processor rather than a miner, offering a route to separated rare earth oxides independent of Mountain Pass.
USA Rare Earth is advancing the Round Top project in Hudspeth County, Texas — a heavy rare earth and critical mineral deposit with a published resource and a pilot processing facility on site. Round Top contains meaningful concentrations of terbium, dysprosium, and yttrium alongside lithium and other critical minerals. The project has received DoD interest and is targeting a production decision in the mid-2020s.
Ucore Rare Metals (TSXV: UCU) is developing its RapidSX separation technology, targeting deployment at a planned strategic metals complex in Louisiana. Ucore has secured a licence from Innovation Metals Corp for the RapidSX solvent extraction platform and is progressing engineering studies for commercial-scale separation capacity. The Louisiana facility, if built, would add US-based heavy rare earth separation capacity currently absent outside of MP Materials’ operations.
Canada Rare Earth — Projects and Producers
Vital Metals (ASX: VML) operates the Nechalacho project in the Northwest Territories — Canada’s first producing rare earth mine, which achieved first ore extraction in 2021. Nechalacho contains a high-grade near-surface zone with elevated NdPr content and a larger, lower-grade resource at depth. Vital Metals has undertaken initial ore sorting and processing trials, though the project remains at an early production stage pending downstream processing arrangements.
Defense Metals (TSXV: DEFN) is advancing the Wicheeda REE project in British Columbia, one of the more advanced rare earth development projects in Canada. Wicheeda contains a carbonatite-hosted deposit with a NI 43-101 resource of approximately 11.3 million tonnes grading 2.86% LREO, giving it meaningful scale relative to peers. A preliminary feasibility study is underway, with the project targeting the NdPr market.
Neo Performance Materials (TSX: NEO) operates rare earth separation and magnet alloy powder facilities in Europe and Asia, with its corporate headquarters in Toronto. Neo is not a Canadian miner but represents the most significant Canadian-listed downstream rare earth processor — and has been actively pursuing supply agreements with North American mining projects to feed its processing operations.

North America Rare Earth — Policy and Investment Context
US federal investment in north america rare earth supply chains has accelerated materially since 2022. DPA Title III funding has been directed at separation and processing capacity — a deliberate focus on the processing bottleneck rather than mine development alone. The DoD has issued grants to MP Materials, Energy Fuels, and USA Rare Earth, among others. The IRA’s critical minerals provisions offer production tax credits for domestically processed rare earth materials meeting content thresholds, providing a long-run incentive for processing investment.
Canada’s federal government has committed CAD 3.8 billion through the Critical Minerals Strategy, with the Canada Infrastructure Bank and Export Development Canada providing additional project finance tools. The Canada–US Critical Minerals Action Plan (2023) includes commitments on data sharing, permitting co-ordination, and joint research. Both governments have signalled that rare earths qualify for the highest tier of strategic priority under their respective frameworks.

North America Rare Earth Outlook
North america rare earth production capacity is expected to increase modestly through 2026–2027, with Mountain Pass remaining the dominant source and White Mesa adding separated output from monazite processing. The near-term constraint is not ore — it is licensed separation capacity capable of producing the high-purity oxides that magnet manufacturers require. MP Materials’ separation ramp and the White Mesa expansion address this, but at a scale that remains a fraction of Chinese output.
Canadian projects face the standard development hurdles: permitting timelines in the two-to-four-year range for advanced projects, infrastructure gaps in remote jurisdictions (Nechalacho’s Northwest Territories location requires fly-in access and offsite processing), and financing markets that remain selective for pre-revenue miners. Wicheeda and similar carbonatite-hosted deposits carry lower metallurgical risk than ionic clay deposits but require capital-intensive processing circuits.
The policy environment is the strongest it has been for North American producers, and allied-nation offtake — from Japan, South Korea, and the EU — is emerging as a financing lever for projects that can demonstrate permitting progress and bankable feasibility studies. The medium-term outlook for north america rare earth supply is cautiously constructive, contingent on processing investment keeping pace with mine development.

Which country produces the most rare earths in North America?
The United States is the largest rare earth producer in North America, primarily through MP Materials’ Mountain Pass mine in California, which produced approximately 45,000 tonnes of rare earth oxide concentrate in 2024. Canada has reached early-stage production at the Nechalacho project in the Northwest Territories but remains at a fraction of US output volumes.
What is North America’s share of global rare earth production?
The United States accounts for roughly 12–14% of global rare earth mine production, according to USGS data. Canada’s contribution remains small but is growing as projects advance from development to production. Combined, North America represents a meaningful but minority share of global supply, which is still dominated by China at approximately 60%.
What are the key north america rare earth projects outside Mountain Pass?
Key projects include Energy Fuels’ White Mesa Mill in Utah (US-based rare earth processing from monazite), USA Rare Earth’s Round Top deposit in Texas (heavy rare earth focus), Vital Metals’ Nechalacho mine in Canada’s Northwest Territories, and Defense Metals’ Wicheeda project in British Columbia. Ucore Rare Metals is developing separation technology for a planned Louisiana processing facility.
How is the US government supporting rare earth production?
The US government has deployed multiple tools: Defence Production Act (DPA) Title III grants to producers and processors, Department of Defence direct funding to MP Materials, Energy Fuels, and USA Rare Earth, and Inflation Reduction Act critical minerals tax credits for domestically processed materials. These programmes target the full supply chain from mine to magnet, with particular emphasis on closing the processing and separation gap relative to China.
Does Canada have significant rare earth deposits?
Yes. Canada hosts several advanced rare earth development projects, including Vital Metals’ Nechalacho deposit in the Northwest Territories and Defense Metals’ Wicheeda carbonatite project in British Columbia. Canada’s Critical Minerals Strategy commits CAD 3.8 billion to development across priority minerals including rare earths, and a bilateral action plan with the United States supports project co-ordination and data sharing.
