Rare Earths Norway has announced a substantial upgrade to mineral resources at its Fen project, describing the deposit as Europe’s largest rare earth accumulation and a potential cornerstone of the continent’s strategic supply chain.
According to a revised estimate prepared by consulting firm WSP, indicated and inferred resources at Fen now total 15.9 million tonnes of rare earth oxides, an 81 percent increase from the 8.8 million tonnes reported in 2024. The updated figures place Fen well ahead of Sweden’s Per Geijer deposit, previously cited by LKAB as Europe’s largest rare earth discovery.
Bernd Schaefer, CEO of EIT RawMaterials, said the resource expansion elevates Fen from a promising discovery to what he described as a world-class strategic asset. He noted the project could serve as the foundation for a compact “mine-to-magnet” value chain within Europe, supporting industrial resilience and long-term raw material security.
Europe currently has no operating rare earth mines, leaving the region heavily dependent on imports. Eurostat data show that in 2024, 95 percent of the European Union’s rare earth imports originated from China, Malaysia and Russia. The development of Fen would support EU efforts to diversify supply and reduce strategic vulnerability.
Rare earth elements are essential for advanced defence systems, including precision motors and sensors used in naval vessels, fighter aircraft and drones, as well as permanent magnets required for electric vehicles, wind turbines and consumer electronics. The latest resource estimate indicates that approximately 19 percent of Fen’s oxides consist of neodymium and praseodymium, key materials for high-performance magnets. The deposit also contains notable quantities of niobium and thorium.
Rare Earths Norway has previously outlined plans to commence production in late 2031, targeting annual output of 800 tonnes of NdPr by 2032, equivalent to roughly 5 percent of projected EU demand. While the company holds an extraction permit, it still requires an operating permit before mining can begin. The latest announcement did not revise projected timelines or production targets.
The project aligns with the EU’s ResourceEU action plan adopted in December 2025, which seeks to accelerate domestic extraction, processing and recycling of critical minerals. However, current EU policy does not restrict the export destinations of rare earths mined within the bloc, meaning production could still be sold to non-European markets.
