Top 10 North America Rare Earth Projects 2026

The ten most significant north america rare earth projects span three countries, four geological deposit types, and every stage of development from surface outcrop to active production — collectively representing the western world’s best near-term answer to Chinese dominance of rare earth supply. US executive orders designating critical minerals a national security priority, combined with Canadian federal funding through the Critical Minerals Infrastructure Fund, have accelerated permitting and feasibility timelines across the sector since 2022. For a full regional overview, see our North America rare earth hub.

How We Ranked North America Rare Earth Projects

Projects are assessed on four criteria weighted in order: resource scale (measured and indicated TREO tonnage where available), project maturity (scoping study through to operating status), strategic element mix (NdPr and HREE weighting above lanthanum/cerium-dominant deposits), and proximity to or ownership of processing infrastructure. Producing operations rank above advanced-stage projects regardless of resource size. All resource figures are company-reported unless otherwise stated; investors should refer to current NI 43-101 or JORC technical reports.

Top 10 North America Rare Earth Projects Ranked

1. Mountain Pass — California, USA (MP Materials, NYSE: MP)

Mountain Pass is the only operating rare earth mine in North America and the continent’s largest REE producer by volume. MP Materials reports annual production of approximately 42,000 tonnes of rare earth oxide equivalent, making it one of the five largest REE mining operations globally. The deposit is a carbonatite with well-established infrastructure including an on-site concentration facility. MP is expanding into separated NdPr oxide production at Mountain Pass under its Stage II programme, targeting magnet-ready output for the US defence and EV supply chains. The principal constraint is that the mine currently ships concentrate to China for separation — a dependency Stage II is designed to eliminate by 2026–27.

2. Nechalacho — Northwest Territories, Canada (Vital Metals, ASX: VML)

Nechalacho became the first new rare earth mine opened in Canada in decades when Vital Metals began ore extraction in 2021. The deposit contains an estimated 94.7 million tonnes at 1.46% TREO in the indicated and inferred categories, with near-surface mineralisation amenable to selective mining. The project targets the Tardiff Zone for higher-grade ore and ships concentrate for processing. Vital Metals has faced financing constraints in recent years, and project pace is contingent on capital availability. Nechalacho’s primary value is its NdPr content and its status as proof that Canadian REE projects can move from resource to production.

3. Wicheeda — British Columbia, Canada (Defense Metals, TSXV: DEFN)

Wicheeda is among the most advanced undeveloped NdPr projects in Canada. Defense Metals completed a Definitive Feasibility Study in 2024, reporting a resource of 11.1 million tonnes measured and indicated at 2.95% TREO — one of the highest average grades among North American carbonatite deposits. The DFS outlined a 22-year mine life producing approximately 8,000 tonnes of REO per year. The Canadian government awarded C$2.9 million in federal funding in 2025 to advance environmental permitting. Wicheeda’s risk is financing — the project requires significant capital and has not yet secured a processing partner or binding offtake.

4. Ashram — Québec, Canada (Commerce Resources)

Ashram is one of the largest undeveloped rare earth deposits in the world by contained TREO, with a resource exceeding 220 million tonnes at 1.77% TREO in the measured, indicated, and inferred categories — placing it in the same tier as globally significant deposits. Commerce Resources (TSXV: CCE) completed a Preliminary Feasibility Study that confirmed favourable mineralogy for conventional flotation-hydrometallurgical processing. Ashram is LREE-dominant (La, Ce, Nd, Pr), which limits its premium element yield relative to HREE-enriched projects. The primary constraint is project stage — Ashram remains at PFS, and moving to DFS and permitting will require substantial capital and a longer development timeline than projects already at DFS stage.

5. Round Top — Texas, USA (USA Rare Earth)

Round Top is a rhyolite-hosted deposit in west Texas with an unusually broad critical mineral suite including heavy rare earths, lithium, beryllium, and uranium. USA Rare Earth has advanced the project to a construction-stage processing facility in Corsicana, Texas, designed to produce separated REE oxides. The deposit’s HREE enrichment — particularly terbium, holmium, and yttrium — differentiates it from most North American REE projects, which are LREE-dominant. Resource scale is more modest than the top carbonatite projects, but the multi-mineral economics and Texas processing infrastructure investment are strategically significant. See our United States rare earth overview for broader US project context.

6. White Mesa Mill — Utah, USA (Energy Fuels, NYSE American: UUUU)

White Mesa Mill is the only operating conventional rare earth processing facility in the United States — making it strategically distinct from every other entry on this list. Energy Fuels processes alternate feed materials (uranium-bearing ores from third-party mines) to produce mixed rare earth carbonate, which it supplies to Neo Performance Materials for downstream separation. The mill does not mine REEs directly; its value is as processing infrastructure in a country with almost no domestic separation capacity. Energy Fuels is developing an on-site REE separation capability targeting separated NdPr oxide. For neodymium price context, this separation buildout is one of the few western-hemisphere projects that could directly influence NdPr supply outside China within this decade.

7. Ucore Rare Metals — Alaska, USA (TSXV: UCU)

Ucore Rare Metals is developing a rare earth separation and processing hub strategy centred on its proprietary RapidSX™ solvent extraction technology. Ucore is constructing a Strategic Metals Complex (SMC) in Louisiana, targeting commercial-scale separation of NdPr and HREE oxides from third-party feedstock — positioning itself as a processing company rather than a miner. The Bokan-Dotson Ridge deposit in southeast Alaska provides a longer-term mining asset with significant HREE content including dysprosium and terbium. See our dysprosium price page for supply context on HREE. Ucore’s near-term value lies in the Louisiana SMC, not the mine, and timeline execution remains the key risk.

8. Montviel — Québec, Canada (Geomega Resources)

Montviel is a large carbonatite-hosted REE deposit in northern Québec with a resource of approximately 566 million tonnes inferred at 1.35% TREO — one of the largest by total tonnage in Canada. Geomega Resources (TSXV: GMA) is developing an ionic-exchange processing route that avoids conventional acid leaching, potentially reducing processing costs and environmental footprint. The deposit is LREE-dominant. Montviel is at a relatively early stage compared to Wicheeda or Ashram and faces the standard infrastructure challenges of remote Québec projects including road access and power. Geomega’s dual focus on Montviel and its ISR recycling technology for NdFeB magnet waste adds optionality but dilutes near-term project focus.

9. Alces Lake — Saskatchewan, Canada (Appia Rare Earths & Uranium, TSXV: API)

Alces Lake contains some of the highest-grade surface-accessible rare earth mineralisation in North America, with drill results consistently returning greater than 10% TREO in narrow zones with exceptional heavy rare earth enrichment including terbium, dysprosium, and holmium. Appia Rare Earths is advancing exploration across the property. The project is at an early stage — no resource estimate that would support economic assessment has been completed — and the high-grade zones are structurally complex and narrow, creating metallurgical and scale challenges. Alces Lake’s strategic value lies in its HREE grade; its near-term production potential is limited without significant further work and financing.

10. Bear Lodge — Wyoming, USA (Rare Element Resources)

Bear Lodge is a carbonatite-hosted REE deposit in Wyoming with a measured and indicated resource of approximately 18 million tonnes at 3.05% TREO. Rare Element Resources (OTC: REEMF), in which General Atomics holds a significant stake, is developing a proprietary selective extraction process (WPEx™) targeting a low-cost processing flowsheet without conventional solvent extraction. A demonstration plant has been built to prove the technology at scale. Bear Lodge is NdPr-enriched relative to most North American carbonatites but has faced a lengthy permitting and financing timeline. Progress on the WPEx demonstration plant is the key near-term milestone.

North America Rare Earth Projects — Summary Comparison

The Outlook for North America Rare Earth Projects

The pipeline of north america rare earth projects is deeper than at any point since the Mountain Pass closure in 2002, but capital remains the binding constraint across nearly every non-producing entry on this list. US Department of Defense Title III funding and the Canadian Critical Minerals Infrastructure Fund have provided grant capital to advance permitting and feasibility work, but none of the pre-production projects has secured full project financing. The projects most likely to reach construction decisions in the 2026–28 window are Wicheeda — which has a completed DFS and federal support — and Energy Fuels’ White Mesa separation expansion, which benefits from existing licensed infrastructure. According to USGS data, the US imported approximately 74% of its rare earth compounds and metals in 2024, with China the dominant supplier — a figure that underscores the strategic urgency behind this project pipeline. Natural Resources Canada identifies rare earths as a priority critical mineral under its 2022 Critical Minerals Strategy, which targets federal investment in exploration, processing, and recycling infrastructure.
