The pipeline of rare earth mining projects outside China has reached an inflection point in 2026. Final investment decisions, government-backed financing packages, and a rash of strategic acquisitions have moved several assets from development-stage speculation into funded construction. This briefing covers the most significant active and advancing rare earth mining projects globally, with status verified as of June 2026. Production data is sourced from the USGS Mineral Resources program; project-level data is drawn from company disclosures and exchange filings.
Why Rare Earth Mining Projects Are Attracting Record Capital in 2026
China controls approximately 60% of global rare earth mine production and over 90% of processing capacity. Export controls on rare earth processing technology, introduced in late 2024 and extended in scope through 2025 and 2026, have made the case for Western rare earth mining projects more urgent than at any prior point. US, EU, and allied government financing — through mechanisms including the US International Development Finance Corporation (DFC), export credit agencies, and the EU Critical Raw Materials Act framework — is now flowing into projects that would have struggled to reach FID on commercial capital alone. See our analysis of China’s rare earth export controls for the regulatory context driving this investment surge.
Nolans Bore, Australia — FID Reached May 2026
Arafura Rare Earths (ASX: ARU) took its Final Investment Decision on 21 May 2026, moving the Nolans Bore project in Australia’s Northern Territory from development into execution. Construction is scheduled to commence in September 2026, with first production targeted for mid-2029. The project is designed to produce 4,440 metric tonnes of NdPr oxide annually over an approximately 38-year mine life — representing up to 4% of projected global NdPr demand.
Nolans is notable among rare earth mining projects for its fully integrated design: ore extraction, beneficiation, hydrometallurgical processing, and rare earth separation all occur within a single Northern Territory site, eliminating the logistical exposure created when mining and processing occur in separate jurisdictions. Financing is drawn from a multi-sovereign export credit agency syndicate involving the US, Canada, Germany, and South Korea, alongside the Northern Australia Infrastructure Facility. Hatch has been appointed as EPCM contractor — details in the Arafura Nolans project page. A second equity tranche of approximately A$174.5 million remains subject to shareholder approval at an EGM scheduled for July 2026.
Serra Verde (Pela Ema), Brazil — Operating; Acquisition Pending
Serra Verde’s Pela Ema mine in Goiás state, Brazil, is the only large-scale producer of all four magnetic rare earths — neodymium, praseodymium, dysprosium, and terbium — outside Asia. The mine began commercial production in 2024 and is already operating at a scale that Serra Verde expects will account for approximately half of global ex-China rare earth production within the next year.
In April 2026, USA Rare Earth (Nasdaq: USAR) announced a definitive agreement to acquire Serra Verde for approximately $2.8 billion — $300 million in cash plus 126.9 million shares. The transaction, expected to close in Q3 2026, is subject to regulatory approval; Brazil’s antitrust watchdog opened an investigation in May 2026, adding a procedural hurdle to the timeline. A 15-year US government-backed offtake agreement covers 100% of Pela Ema’s Phase 1 NdPr, dysprosium, and terbium production. The $565 million DFC financing package closed earlier in 2026 and is being deployed for operational upgrades. This is the most strategically significant of the current rare earth mining projects for Western HREE supply chain diversification. For pricing context on the elements Serra Verde produces, see our dysprosium price tracker and terbium price tracker.
Tanbreez, Greenland — Advanced Exploration; Pilot Plant Underway
The Tanbreez project in southern Greenland holds one of the world’s largest rare earth resource bases — a 4.7 billion tonne total resource with approximately 27% heavy rare earth concentration — and has become a focus of US government strategic interest in 2026. Critical Metals Corp (Nasdaq: CRML) secured Greenland government approval in April 2026 to take its ownership to 92.5%. The project cleared its core environmental permit for the Hill Block in 2026 — the primary regulatory hurdle before production.
Pilot plant operations commenced in May 2026, with a 150-tonne bulk sample programme planned for June 2026. A metallurgical breakthrough announced in March 2026 demonstrated a ~40% improvement in refined concentrate grade, achieving 2.96% TREO. Tanbreez is not yet a producing rare earth project — commercial production must commence by end of 2028 under the terms of its exploitation licence. What distinguishes it from most development-stage rare earth mining projects is its low uranium content (below Greenland’s 100ppm threshold), resolving the permitting constraint that blocked the competing Kvanefjeld project. See our Greenland rare earth country profile for full context.
Nolans vs Serra Verde vs Tanbreez: A Comparison
| Project | Operator | Location | Status (June 2026) | Primary REEs | First Production |
|---|---|---|---|---|---|
| Pela Ema (Serra Verde) | USA Rare Earth (acq. pending) | Goiás, Brazil | Operating | NdPr, Dy, Tb, Y | Operating since 2024 |
| Nolans Bore | Arafura Rare Earths (ASX: ARU) | Northern Territory, Australia | FID reached; construction Sep 2026 | NdPr oxide | Mid-2029 (target) |
| Tanbreez | Critical Metals Corp (Nasdaq: CRML) | Southern Greenland | Advanced exploration; pilot plant active | HREE-rich mixed | By end 2028 (licence requirement) |
| Round Top | USA Rare Earth (Nasdaq: USAR) | Texas, USA | Development; target production 2028 | Heavy REEs | 2028 (target) |
| Mount Weld | Lynas Rare Earths (ASX: LYC) | Western Australia | Operating | NdPr, Ce, La | Operating |
Mountain Pass and the US Domestic Rare Earth Mining Projects
Mountain Pass in California, operated by MP Materials (NYSE: MP), remains the only operating rare earth mine in the United States — producing approximately 45,000 MT annually of light rare earth concentrate. By 2026, MP Materials’ Fort Worth, Texas magnet manufacturing facility is in active commissioning, pursuing a mine-to-magnet domestic supply chain. Mountain Pass produces no meaningful heavy rare earth output; US dependency on Myanmar and China for dysprosium and terbium feedstock remains unresolved, making the Serra Verde acquisition by USA Rare Earth strategically significant for the broader US rare earth mining projects picture.
Lynas Rare Earths (ASX: LYC) continues to operate Mount Weld in Western Australia — the highest-grade known rare earth deposit outside China — while advancing its Kalgoorlie processing facility to reduce dependency on the Malaysian LAMP plant.

The Outlook for Rare Earth Mining Projects Outside China
The 2026 investment surge into rare earth mining projects represents a structural shift rather than a cyclical response. Government financing has moved from supplementary to foundational — most of the projects reaching FID or construction in 2026 would not have done so on commercial capital alone at current NdPr prices. The constraint that remains: processing. Most rare earth mining projects outside China still depend on Chinese separation capacity at some point in the value chain. The Nolans integrated design and Serra Verde’s on-site processing are the exceptions. Building Western separation infrastructure is the decade-defining challenge that exploration and mining alone cannot resolve. For the supply chain risks that sit behind these rare earth mining projects, see our rare earth supply chain analysis and our ranking of rare earth refining companies outside China. For current NdPr pricing — the commercial output that determines project economics — see the neodymium price tracker.

What is the most significant rare earth mining project outside China in 2026?
Serra Verde’s Pela Ema mine in Goiás, Brazil, is currently the most strategically significant operating rare earth mining project outside China — the only large-scale producer of all four magnetic rare earths (neodymium, praseodymium, dysprosium, and terbium) outside Asia. USA Rare Earth (Nasdaq: USAR) announced a $2.8 billion acquisition of Serra Verde in April 2026, pending regulatory approval expected in Q3 2026.
What is the status of the Nolans Bore rare earth project in 2026?
Arafura Rare Earths (ASX: ARU) reached Final Investment Decision on 21 May 2026. Construction is scheduled to commence in September 2026, with first production targeted for mid-2029. Nolans is designed to produce 4,440 metric tonnes of NdPr oxide annually and is one of the few rare earth mining projects with fully integrated on-site processing from ore to separated oxide.
Why is the Tanbreez project in Greenland strategically important?
Tanbreez holds a 4.7 billion tonne total resource with approximately 27% heavy rare earth concentration — one of the largest known deposits of dysprosium and terbium outside China. Critical Metals Corp (Nasdaq: CRML) reached 92.5% ownership in April 2026 and commenced pilot plant operations in May 2026. Unlike the blocked Kvanefjeld project, Tanbreez qualifies under Greenland’s uranium mining ban as its uranium content falls below the 100ppm threshold.
Why are Western governments funding rare earth mining projects directly?
Most rare earth mining projects outside China cannot reach Final Investment Decision on commercial capital alone at current NdPr prices. Government financing — through the US International Development Finance Corporation, export credit agencies from the US, Canada, Germany and South Korea, and the EU Critical Raw Materials Act framework — has become foundational rather than supplementary to project economics in 2026, filling the gap that private capital alone cannot close.
What is the difference between a rare earth mine and a rare earth processing facility?
A rare earth mine extracts ore from the ground; a processing or separation facility converts that ore into separated rare earth oxides suitable for magnet or industrial use. Most rare earth mining projects outside China still depend on Chinese processing capacity at some point in the value chain. Nolans Bore and Serra Verde’s Pela Ema are notable exceptions — both are designed with on-site integrated processing, eliminating the need to ship concentrate to China for separation.
