ETM–Greenland rare earth dispute: licensing and risk takeaways for mine planners

30 Second Briefing
Energy Transition Minerals claims Greenland has effectively expropriated the Kvanefjeld rare earth project by refusing to renew its exploration licence and applying Act 20’s 100 ppm uranium limit retroactively to block a mining licence lodged in 2020. The company says it has invested about US$150 million since 2013 and argues 2025 drilling identified rare earth mineralisation below the uranium threshold in largely untested parts of the licence, alongside proposals to separate uranium from concentrate and return it underground. Greenland cites community opposition near Narsaq, while ETM pursues arbitration and diversifies with the Penouta brownfield tantalum project in Spain.
Technical Brief
- Act 20 sets a hard uranium cut-off at 100 ppm (0.01%) for project approval.
- ETM advanced Kvanefjeld through full resource definition, environmental studies and statutory public consultation before lodging its 2020 mining application.
- Greenland renewed ETM’s exploration licence on a three‑year cycle, including once after Act 20, before the current refusal.
- Explanatory notes to Act 20 allow waivers where strict application would constitute expropriation, now central to arbitration arguments.
- ETM contends 2025 drilling targeted largely untested licence areas, delineating REE zones with uranium below the statutory limit.
- Proposed flowsheet changes included uranium separation from rare earth concentrate and permanent subsurface reinjection of the uranium stream.
- Kvanefjeld’s Nd, Pr, Dy and Tb output has been promoted as potentially supplying up to 15% of global rare earth production.
- Greenland’s government cites sustained local opposition near Narsaq, focused on uranium and broader environmental impact concerns.
- In parallel, ETM is repositioning with the Penouta brownfield tantalum restart in Spain as a separate European critical minerals asset.
Our Take
Our database shows that while Kvanefjeld in Greenland is stalled in arbitration, ETM has been pivoting capital and management attention towards the Penouta tin–tantalum–niobium asset in Spain, which already has a Section C concession approval and therefore offers a lower permitting-risk pathway to critical minerals exposure in Europe.
The related May 18, 2026 analysis of Kvanefjeld highlights permitting and regulatory stability as a key execution risk for critical minerals; combined with Greenland’s 100 ppm uranium threshold, this signals that future rare earth projects with uranium by‑products will likely need front‑loaded social licence and radiological management strategies to avoid similar stand‑offs.
