Insights

Critical Metals advances Tanbreez rare earth project with 70% BFS completion, positioning for potential production of strategic minerals by 2026.

Critical Metals Corp has reached a significant milestone with approximately 70% completion of the Bankable Feasibility Study (BFS) for its Tanbreez Rare Earth Project in South Greenland. The BFS, led by Danish engineering firm NIRAS, remains on schedule for submission in Q4 2025 and will cover a 500,000 tons per annum mining and processing operation.

The engineering scope encompasses comprehensive designs for open pit mining, processing infrastructure, and environmental management. Key components include mine design with blasting and haulage logistics, crushing and magnetic separation circuits, slurry transport systems, and tailings deposition infrastructure. The project also includes port facilities, haul roads, power generation, and worker accommodation.

What's particularly noteworthy is the integration of environmental considerations directly into the technical design phase. NIRAS is incorporating hydrological modeling, dust dispersion controls, and closure planning into the final design � elements that are increasingly critical for securing regulatory approvals in environmentally sensitive regions like Greenland.

The company has also completed its 2025 environmental baseline sampling program, which included comprehensive monitoring across 19 freshwater stations, sediment coring, and various ecological assessments. This environmental work will support the Environmental Impact Assessment (EIA) required for final regulatory approval.

The Tanbreez project represents a potential new source of rare earth elements, which are critical materials for high-tech applications including renewable energy technologies, electric vehicles, and defense systems. With rare earth supply chains dominated by China, new Western-controlled sources have significant strategic importance. However, investors should note that significant regulatory hurdles remain before commercial production could begin, including final approval from Greenland's Mineral License and Safety Authority following the BFS submission.

NEW YORK, Sept. 02, 2025 (GLOBE NEWSWIRE) -- Critical Metals Corp. (Nasdaq: CRML) (“Critical Metals Corp� or the “Company�), a leading critical minerals mining company, today announced that Tanbreez Mining Greenland A/S (“Tanbreez�) is approximately 70% complete on the final stages of the Bankable Feasibility Study (BFS) for a 500,000 tons per annum mining and processing operation at the Tanbreez Rare Earth Project in South Greenland. The BFS is being led by Danish engineering firm NIRAS A/S (“NIRAS�), a globally leading multidisciplinary engineering and environmental consultancy based in Denmark. The BFS remains on track for submission in Q4 2025. In addition, NIRAS has completed environmental fieldwork for the 2025 baseline sampling program.

Tony Sage, Executive Chairman of the Company, commented:

“The progress on the final BFS engineering and the completion of the 868 baseline sampling program represent a major milestone in unlocking the full potential of the Tanbreez Rare Earth Project. Our partnership with NIRAS ensures that both technical and environmental aspects are being addressed to the highest standards, reinforcing our commitment to responsible development.�

This final BFS phase includes:

Completion of mine design and process plant engineering
Tailings management and water treatment strategies
Integration of environmental and regulatory inputs
Preparation of documentation for submission to Greenland’s MLSA

Proposed plant and port site.

The engineering scope encompasses detailed design of the two open pit mining phases, including blasting and haulage logistics, crushing and magnetic separation circuits, slurry transport systems, and tailings deposition infrastructure at Lake Foster. It also includes port and haul road layouts, diesel power generation, and worker accommodation facilities. NIRAS is integrating hydrological modelling, dust dispersion controls, and closure planning into the final design to ensure long-term environmental compliance, operational efficiency, and alignment with Greenland’s regulatory framework.

Completion of 2025 Baseline Sampling Program

In parallel, Critical Metals Corp confirms that environmental fieldwork for the 2025 baseline sampling program has officially been completed. This program—coordinated by NIRAS ran through August 2025 and was designed to close spatial and seasonal gaps in the existing baseline dataset.

Key components of the sampling campaign included:

  • Bergerhoff dust monitoring
  • All-year freshwater sampling across 19 stations
  • Sediment coring in Lake Foster and Kangerluarsuk Fjord
  • Arctic char population update via electrofishing
  • Intertidal sampling of mussels, bladderwrack, and sea scorpion

About Tanbreez

The Tanbreez Rare Earth Project is one of the world’s largest hard rock rare earth elements (REE) deposits, located in southern Greenland near the town of Qaqortoq. The project is notable for its high concentration of heavy rare earth oxides (HREOs), which are critical for high-tech applications, clean energy, and defence industries. Unlike other major TREO deposits, Tanbreez contains very low levels of uranium and thorium, making it more environmentally and politically viable.

  • Deposit Type: Kakortokite (a stratiform layered igneous rock rich in TREOs)
  • Kakortokite Estimate: ~4.7 billion tonnes of REE-bearing mineralisation
  • Heavy REE Content: ~27% of Total Rare Earth Oxides (TREO)
  • Location: Near Qaqortoq, southern Greenland
  • Target drilling: ongoing to achieve Measured and Indicated Mineral Resources
  • Project Stage: advanced Bankable Feasibility Study phase

Kakortokite host may not always contain any economic mineralisation of TREO.
