Critical Metals’ Greenland Tanbreez plan: project finance and schedule lens for engineers
Reviewed by Joe Ashwell

First reported on MINING.com
30 Second Briefing
Critical Metals has begun a strategic review that could see it sell, spin off or partner non-core assets to accelerate its Tanbreez heavy rare earth project at Killavaat Alannguat in southern Greenland, hiring Clear Street and White & Case LLP to run the process. Tanbreez, fully acquired in April, carries a preliminary economic assessment value of about $3 billion on a 4.7‑billion‑tonne resource across two deposits and already has offtake agreements for roughly 75% of future output. Up to $120 million in US EXIM financing is in place, with first ore targeted for late 2028 or early 2029.
Technical Brief
- Strategic review explicitly considers asset sales, joint ventures, alliances or full business separations across the portfolio.
- Clear Street appointed as financial adviser and White & Case LLP as legal adviser for the process.
- Company flags no assurance any transaction will occur, so Tanbreez funding plan still partly contingent.
- Project characterised as one of the largest undeveloped heavy rare earth deposits outside China, shaping market positioning.
- Critical Metals aims to become a “pure-play Western source” of heavy rare earths and critical minerals.
- Portfolio streamlining is intended to reallocate both capital and execution capacity directly into Tanbreez development.
Our Take
In our database, Tanbreez is one of the few heavy rare earth projects outside China with both a long-term offtake (the 15‑year REalloys deal) and a prospective US Export‑Import Bank link, which makes asset sales a relatively low‑dilution way for Critical Metals to unlock the US$3 billion PEA valuation.
The 4.7 billion‑tonne resource at Killavaat Alannguat positions Tanbreez at the very large end of rare earth deposits in our coverage, so any asset divestments are likely to be judged by investors on whether they accelerate first production into the stated 2028–2029 window rather than on pure portfolio rationalisation.
Compared with other Western Hemisphere rare earth and critical minerals financings we track, Critical Metals’ mix of Greenland exposure and a US‑centric financing/offtake ecosystem (REalloys, US EXIM) suggests the company is targeting premium strategic pricing rather than competing directly with lower‑cost Chinese supply.
