Rare Earth Minerals in USA Map: Mines, Data and Status

Overview of US Rare Earth Minerals (REMs): National Significance in 2025–2026

The United States is at a turning point regarding rare earth minerals (REMs)—a group of 17 chemically similar elements that are essential for the supply of advanced manufacturing, defense technologies, and the next generation of infrastructure and sustainable energy systems. In 2026, the strategic management and development of these critical mineral resources have shifted from being a long-term aspiration to an urgent national priority underscoring both economic security and technological leadership for the country.

Quick answer. The United States mined an estimated 51,000 tons of rare earth oxide in mineral concentrates in 2025, worth about US$240 million. Bastnaesite (a rare earth carbonate mineral) from Mountain Pass, California, made up almost all of it, and monazite (a rare earth phosphate mineral) from heavy-mineral sands in the southeastern states added a smaller stream (USGS Mineral Commodity Summaries, 2026). That is second place behind China at 270,000 tons. USGS puts US reserves, the part that is economic to mine today, at 1.9 million tons of rare earth oxide, against 44 million tons for China.

On counting: USGS defines the rare earth elements as the 15 lanthanides plus yttrium (USGS SIR 2010-5220). Adding scandium gives the 17 elements often quoted. The map and tables below show where the deposits sit and what stage each project has reached.

Rare earth minerals—despite the misleading “rare” label—are relatively abundant globally, including across the USA. Yet, most REMs are seldom found in economically extractable concentrations. Their strategic importance lies in producing permanent magnets for electric vehicles (EVs), wind turbines, consumer electronics, modern batteries, and core defense systems.

2025–2026 Strategic Mining Trends & Industry Revival: The Rise of Domestic Producers

The early 2020s saw the USA address the vulnerabilities of an overreliance on foreign supply chains—especially China, which accounted for the vast majority of global rare earth production over recent decades. The shift has led to the strategic revival of domestic mining and processing capacity, with MP Materials and other developers restoring America’s mineral production capabilities.

Federal initiatives in 2025 have focused on revitalizing existing mines like the Mountain Pass mine in California—historically the nation’s REM flagship—and supporting the development of new extraction sites in Alaska, Wyoming, and the Appalachian region.

• ✔ Advanced Technologies: AI, satellite mapping, and remote sensing accelerate resource assessment.
• 📊 Federal Projects: New initiatives increase domestic supply and invest in infrastructure.
• ⚠ Risk: Environmental management and community acceptance are critical challenges.
• ✔ Economic Diversification: Rare earth mining supports job creation in rural mining communities.
• 💡 Innovation: Integration of satellite-based mineral detection enhances early-stage exploration efficiency.

Rare Earth Minerals in USA Map: Geographic Hotspots & Key Deposits

The rare earth minerals in USA map for 2025–2026 is a showcase of critical deposits and emerging sites that form the backbone of the country’s rare earth infrastructure. Several zones stand out for their estimated reserves, prospective mineral types, and their roles in national supply chains:

• Mountain Pass, California: The largest US producer, historically significant, yielding key REMs like neodymium, praseodymium, cerium, and lanthanum.
• Bokan Mountain, Alaska: Notable for rich heavy rare earths (yttrium, dysprosium), important for advanced electronics and defense.
• Bear Lodge, Wyoming: In federal permitting; the Bull Hill resource averages 4.08% TREO (measured and indicated, company, 2024).
• Appalachian Basin: Unique potential from mining residues, with REMs linked to coal and phosphate extraction.
• Other Strategic Deposits: Texas, Idaho, and ongoing discoveries across Western and Southeastern US states, driving diversification and resilience.

Rare earth deposits map by state: projects and status

The list below covers the rare earth deposits and projects that matter most for a rare earth mines map of the United States. Stage and figures are as last reported by each operator or agency.

For a longer list of owners and project status, see our guide to US rare earth deposits, projects and owners. Note that rare earths are not precious metals. If you want one US map with rare earths next to gold, silver or copper, filter the USGS database below by commodity.

Where to find rare earth project data and mine locations

Five public sources cover most of what a claim owner, consultant or investor needs:

• USGS Scientific Investigations Report 2010-5220. It summarizes the principal US deposits state by state and includes an index map in PDF and TIF form (report page). The geology is sound, but the status text dates from 2010.
• USGS Mineral Resources Data System (MRDS). Reports on deposits worldwide, with name, location, commodity, reserves and references, a map viewer and downloads. WMS and WFS services load it into GIS software. USGS stopped systematic updates in 2011, and the Alaska Resource Data File is the fuller record for Alaska (MRDS).
• USGS Mineral Commodity Summaries. Yearly production and reserves by country, revised each February (rare earths chapter).
• Company technical reports and filings. US-listed firms file reserve and resource reports under SEC Regulation S-K 1300, as Rare Element Resources did for Bull Hill. Canadian-listed firms use NI 43-101, and Ucore’s 2026 report follows both. Australian-listed firms announce through the ASX.
• Federal Permitting Dashboard. Projects under FAST-41, such as Bear Lodge, show their review timetable there (Permitting Council notice).

Satellite imagery adds a screening layer. Before you stake or buy ground near a known carbonatite or alkaline intrusion, imagery can map rock types, alteration and structure to rank where to sample first. It does not detect rare earth elements directly, so rock sampling and assays still set the grade. Farmonaut delivers this kind of screening as exploration targets, ahead of a resource estimate.

Claim, licence and land-access rules differ by state and agency. Check with the BLM or a qualified professional, and plan field safety before any site visit.

Key Rare Earth Mineral Deposits and Strategic Insights in the USA (2025-2026)

Reserves, resources and what the table numbers mean

Only Mountain Pass reports proven and probable reserves in the table above. The other projects report resources, which have not been shown to be economic. Within resources, measured and indicated tonnes carry more confidence than inferred ones. USGS puts measured and indicated US rare earth resources at 3.6 million tons, compared with reserves of 1.9 million tons (USGS, 2026).

Check three things before you compare two projects: the unit (short tons or tonnes), the basis (reserve or resource) and the grade measure (TREO, or only the magnet metals neodymium and praseodymium). A high TREO grade can hide a heavy share of cerium and lanthanum, which sell for about US$1 to US$2 per kg as oxides, against US$69 per kg for NdPr oxide (USGS, 2025 averages). The calculator below turns a tonnage and grade into contained and recoverable oxide.

Technological Infrastructure & Domestic Processing: Building a Sustainable Future

Increased rare earth mineral production is reshaping American infrastructure. The rise of electric vehicles, wind energy farms, and the modernization of defense systems is driving urgent demand for a reliable, domestic supply of REMs.

Examples of Infrastructure Investments (2025–2026):

• Separation capacity at Mountain Pass (CA), where MP Materials made 2,599 tons of NdPr oxide in 2025, and a planned Ucore processing plant in Louisiana
• Federal permitting support, such as the FAST-41 listing of Bear Lodge in Wyoming in March 2026
• R&D programs targeting more energy-efficient, sustainable extraction and processing technologies
• Strategic investments in remediation and environmental management to ensure long-term viability

Supply Chain Strategies & National Security: The Defense Dimension

The US Department of Defense (DoD) places a premium on securing domestic rare earth mineral supply chains due to their role in core defense systems. In the post-2025 defense strategy, the focus is on reducing dependence on foreign elements to mitigate the risks of supply disruptions during periods of international tension.

Strategic Focus Areas (2025–2026):

• ✔ Critical Defense Components: REMs are embedded in precision munitions, radar systems, advanced guidance devices, and secure communication electronics.
• ⚠ Vulnerability: Any bottleneck in import-dependent supply chains (especially from China) creates risk for US national security.
• ✔ Federal Oversight: Increased collaboration with domestic mining operators to scale production and introduce advanced monitoring across key sites.
• ✔ Stockpiling & Resilience: Strategic stockpiles and multi-source strategies are being built for defense stability.

Rare earth supply chain map: mine, separation, metal and magnet

The gaps are in the middle of the chain. USGS estimates net import reliance at 67% of apparent consumption of rare earth compounds and metals in 2025 and 100% for heavy rare earths (rare earths, heavy rare earths). China added export controls on samarium, gadolinium, terbium, dysprosium, lutetium, scandium and yttrium in April 2025 and suspended a wider October expansion for one year in November. A price floor of US$110 per kg for NdPr products at Mountain Pass has applied since 1 October 2025 under MP Materials’ agreement with the Department of War, compared with a 2025 average market price of US$69 per kg (MP Materials).

FAQ: US Rare Earth Minerals Map

Where can I find rare earth project data and mine locations?

Start with the USGS 2010 summary of principal US deposits, which has an index map, and the MRDS database, which you can load into GIS. For current status, use each operator’s SEC, SEDAR+ or ASX filings and the Federal Permitting Dashboard. The data-sources section above lists all five.

How many rare earth mines are in the US?

USGS names one mine that produced rare earths as a primary product in 2025: Mountain Pass, California, where bastnaesite is mined. It also reports monazite produced from heavy-mineral sands in the southeastern states (USGS, 2026). The other projects in the state table are in permitting, study or exploration stages.

Where are rare earth minerals found in Wyoming?

Three projects are best documented. Bear Lodge (Bull Hill) is in northeastern Wyoming and in federal permitting (Permitting Council). Ramaco’s Brook Mine property is near Sheridan (10-Q). American Rare Earths reports the Halleck Creek project.

Are there rare earth deposits in Alaska?

Yes. Ucore Rare Metals holds the Bokan-Dotson Ridge project on Prince of Wales Island, and its April 2026 update reported 24,371 tonnes of measured and indicated contained TREO (Ucore). Its heavy rare earth share makes it a heavy-element target.

Are rare earths precious metals?

No. The rare earth elements are 15 lanthanides plus yttrium, used mainly in magnets, catalysts and electronics, and they are not precious metals such as gold or platinum. To view them together on one US map, filter MRDS by commodity.

What does REM mining mean?

In this article REM is shorthand for minerals rich in rare earths. Geologists and filings write REE for the elements, REO for oxides and TREO for total rare earth oxides. Searching those terms returns the technical reports.

Can satellites find rare earth deposits?

Satellites cannot see rare earth elements directly. They map the host rocks, alteration and structures that guide where to sample, and the result is a ranked set of exploration targets. Sampling and assays confirm grade before any resource estimate.

Conclusion: Strategic Leadership in Critical Minerals and Beyond

In 2026, rare earth minerals continue to be at the heart of US economic development, defense security, and technological innovation. The United States ranks second in mine output and is building separation and magnet capacity, but China still mined more than five times as much in 2025 (USGS, 2026).

The deliberate mapping, extraction, and processing of US rare earths—along with strong national policy support—form the foundation of a secure, resilient, and sustainable future for American industry and national defense.
