Greenland grants long‑term mining approval for Critical Metals’ Tanbreez rare‑earth project
The Government of Greenland formally approved Critical Metals Corp.’s Mining and Closure Plans for the Tanbreez project on September 29, 2026. The approval covers extraction of 19 critical elements, including heavy rare earths and magnet metals, and is valid through September 2050. The company must still obtain activity‑specific operating permits before construction can start. Chairman and CEO Tony Sage said the decision de‑risks the project and clarifies the path to development.
Why it matters
The approval removes a major regulatory hurdle, giving investors clearer visibility on the timeline to develop one of the world’s largest heavy rare‑earth deposits. The company’s next step is to secure the required operating permits, after which construction could commence, potentially unlocking a Western‑aligned supply source for critical minerals.
