Europe just found something massive buried under Norway, and it’s making China very nervous.
Europe’s largest rare earth deposit just got considerably bigger. On March 3, 2026, Rare Earths Norway announced that its Fen Carbonatite Complex in Telemark, southern Norway, had grown 81 percent since the previous evaluation in 2024, reaching 15.9 million metric tons of total rare earth oxide content. The estimate, prepared under the internationally recognized JORC Code by consulting firm WSP, is based on roughly 30,000 meters of drill core analyzed to date, including 10,000 meters drilled during a 2025 campaign.
Two years ago, the same deposit was estimated at 8.8 million tons. The jump also marks a qualitative shift: for the first time, part of the resource has been classified in the higher-confidence “Indicated” category, reflecting more detailed geological knowledge of the site.
Europe has no operating rare earth mines. Demand is climbing as the continent pushes to electrify transport and scale up renewable energy, which puts Fen directly at the center of a supply problem that has been building for years.
The One Mineral China Would Rather Europe Not Find
Rare earth elements are not geologically scarce, but economically viable deposits cluster in very few places. China controls roughly 90 percent of global rare earth processing, and in 2024, 95 percent of EU rare earth imports came from China, Malaysia, and Russia, according to Eurostat. That concentration has moved from a trade concern to a security one.
What makes Fen especially valuable is its mineral composition. Rare Earths Norway reported that 19 percent of the oxides are neodymium and praseodymium, known together as NdPr, upgraded from a previous estimate of 17 percent. These are the primary inputs for permanent magnets used in electric vehicle motors, wind turbines, consumer electronics, and defense systems including advanced sensors, precision motors in fighter jets, and military drones.
No viable substitute exists for NdPr in high-performance magnets at industrial scale. The deposit also contains significant quantities of niobium and thorium, the latter already subject to letters of intent for long-term sale to Thor Medical in Norway and Copenhagen Atomics in Denmark for use in radiopharmaceutical and energy production.
Bernd Schaefer, CEO of EIT RawMaterials, an EU-funded critical minerals agency, described the updated estimate as a turning point: “By nearly doubling its known size, Rare Earths Norway has moved from being a promising discovery to a world-class strategic asset that can single-handedly help de-risk our most vulnerable supply chains.”
Seven Times Bigger Than Its Nearest European Rival
Sweden previously held Europe’s largest known rare earth deposit. LKAB’s Per Geijer site near Kiruna contained around 1.3 million tons of rare earth oxides when announced in 2023, later revised to 2.2 million tons. Fen, at 15.9 million tons, is now more than seven times larger than that figure.
That gap matters for a practical reason. Critical mineral extraction is expensive and capital-intensive. Larger deposits spread permitting costs, infrastructure investment, and operational overhead across more recoverable material, which is what separates a financially viable project from one that is merely technically possible. Fen’s NdPr fraction alone sits at roughly 3 million tons, placing it in a tier where serious industrial output becomes realistic.
Rare Earths Norway has previously said the project could supply around 5 percent of EU demand for NdPr by 2032, based on a planned initial output of 800 tons per year. The company is also developing what it calls an “Invisible Mine” concept, a low-impact extraction method using raise mining techniques developed in collaboration with Montanuniversität Leoben in Austria, designed to reduce surface disruption and disposal requirements compared to conventional approaches.
Permits, Paperwork, and a 2031 Target That Has to Hold
Fen already holds an extraction permit, clearing one significant legal threshold. CEO Alf Reistad told Reuters the project still needs an operating permit and remains in the permitting phase, acknowledging it would require what he called “derisking procedures” before competing on price with Chinese output.
Norway’s Minister of Trade and Industry, Cecilie Myrseth, who appeared alongside Reistad at the PDAC mining convention in Canada the week of the announcement, said the deposit “brings us into an entirely different league” and called on authorities to establish the framework conditions needed to secure Europe’s first rare earth extraction.
Production is not expected before late 2031, with the 800-ton annual NdPr target following in 2032. That volume addresses a portion of EU demand but does not close the broader supply gap alone. Whether the timeline holds depends on regulatory review, and European mining projects have routinely taken longer than planned to clear environmental and community assessment processes.
Europe Wants the Minerals. Now It Has to Prove It Can Extract Them.
The EU’s December 2025 RESourceEU Action Plan targets a reduction of rare earth extraction dependency on a single country from 95 percent to 42 percent by 2030, supported by nearly 3 billion euros in mobilized financing over the next twelve months. Projects like Fen sit at the center of that ambition. The plan also proposes faster permitting for strategic mineral projects across the bloc, which could shorten the regulatory runway Fen faces.
Rare Earths Norway’s immediate task is securing the operating permit, with further drilling and feasibility work continuing to define the deposit’s full extent. The company has set late 2031 as its production start target, a date that will test both its technical readiness and Europe’s ability to turn its stated critical minerals strategy into an operating mine.
