    Critical Metals’ $835M Tanbreez deal: project economics and schedule for mine planners

    First reported on MINING.com

    30 Second Briefing

    Critical Metals plans an $835 million all‑stock acquisition of European Lithium, offering 0.035 CRML share per EUR share to cancel a 34% stake and secure 100% ownership of the Tanbreez rare earth project in southern Greenland. The deal consolidates a 4.7‑billion‑tonne heavy rare earth resource at Killavaat Alannguat, already subject to a preliminary economic assessment valuing the project at about $3 billion. Critical Metals has offtake agreements covering roughly 75% of planned output, $120 million in US EXIM Bank financing lined up, and targets first ore in late 2028 or early 2029.

    Technical Brief

    • Share exchange ratio fixed at 0.035 CRML share for each European Lithium share.
    • Implied transaction value of $835 million derived from 22 April closing prices and FX rates.
    • European Lithium’s 34% CRML stake, worth about $540 million on 22 April, will be cancelled.
    • Cancellation of EUR’s holding increases CRML’s free float and removes a single dominant shareholder.
    • Greenland government has already approved indirect transfer of the Tanbreez licence to Critical Metals.
    • Critical Metals’ market capitalisation rose 5% on announcement, reaching approximately $1.5 billion.
    • Transaction secures the remaining 7.5% Tanbreez interest, taking CRML from 92.5% to full ownership.

    Our Take

    Earlier coverage on 10 March noted Critical Metals committing $30 million to accelerate drilling and engineering at Tanbreez, so moving to 100% ownership now likely streamlines decision-making on that work programme and any redesign ahead of the 2028–29 production window.

    The 23.6% pre-market share price jump reported on 17 April after Greenland approved the indirect Tanbreez licence transfer suggests regulatory risk in southern Greenland has eased for Critical Metals, which is important given the project’s large 4.7-billion-tonne rare earth resource and long permitting tail.

    With US Export-Import Bank already lined up for $120 million of financing at Tanbreez and China named as a comparator in this piece, the deal positions Critical Metals within the small group of non-Chinese heavy rare earth developers in our database that are explicitly leveraging US-backed funding to advance supply outside Asia.

    Tungsten’s turning point: Mt Carbine and Dolphin mine implications for engineers

    Surging tungsten prices and tightening supply chains are pushing Australian projects such as EQ Resources’ Mt Carbine in far north Queensland and Group 6 Metals’ Dolphin mine on King Island towards higher output and accelerated development. Mt Carbine is ramping up from tailings retreatment to open-pit and underground ore, while Dolphin is restarting historic underground workings with a new processing plant targeting high-grade scheelite concentrates. For geotechnical and mining teams, the shift raises demand for hard-rock stoping, ground support in narrow, high-stress veins, and fine-tuning of gravity–flotation circuits for complex skarn ores.

    American Ocean Minerals vessel Anuanua Moana: design and survey notes for engineers

    American Ocean Minerals has deployed its 196‑foot research vessel Anuanua Moana as a dedicated deep-sea exploration and environmental monitoring platform across more than 500,000 km² of Cook Islands EEZ and US‑regulated areas, including AOM Area 1 in the Clarion‑Clipperton Zone and AOM Area 2 in the Penrhyn Basin. The ship carries advanced sonar, subsea tracking, a 6,000‑metre‑rated ROV, and onboard geology, chemistry and biology labs, and has already mapped a 23,500 km² licence in 16 days, supporting estimates exceeding 500 million wet tonnes of polymetallic nodules. Backed by a merger with Odyssey Marine Exploration to form a roughly $1 billion US‑controlled critical minerals company, AOMC has secured compliance for two Deep Seabed Hard Mineral Resources Act applications covering 1.4 billion tonnes of inferred resources, while collecting over three years of baseline ecological data for EIAs and feasibility studies amid strong environmental scrutiny.

    Triton Uranium’s Saskatchewan Atlas project: schedule and PEA lens for mine planners

    Triton Uranium has started on-site development at its Atlas project in Uranium City, Saskatchewan, aiming to fast-track a near-surface, infrastructure-ready open-pit operation and is weighing a 2026 US stock exchange listing via SPAC, backed by nearly US$16 million in private funding. A 10,000-metre drill programme beginning June 2026 will test four priority zones, feeding resource estimates and a preliminary economic assessment later that year. The strategy targets compressed permitting and construction timelines versus typical decade-long uranium developments, leveraging historic workings and modern extraction and processing technologies.
