Tanbreez

What Tanbreez does

Tanbreez Mining Greenland A/S is a fully-permitted rare earth mining development project located in Southern Greenland, near the town of Qaqortoq. The project is centered on a Kakortokite ore body covering an 8 x 5 km area approximately 400 m thick, containing a JORC-compliant resource of 4.7 billion tonnes and an estimated 28.2 Mt of total rare earth oxides (TREO), with over 27% heavy rare earth element (HREE) content — a composition described as the largest undeveloped heavy rare earth deposit outside China and ranked #1 globally by Mining.com. Tanbreez is 92.5%-owned by NASDAQ-listed Critical Metals Corp (CRML), with European Lithium Ltd retaining a 7.5% stake subject to a non-binding acquisition LOI.

The project targets extraction of rare earth elements alongside zirconium, tantalum, niobium, and hafnium, with initial planned production of 85,000 tonnes of rare earth oxides per annum, scalable to 425,000 tonnes. Independent testing in March 2026 confirmed a 40% improvement in refined concentrate grade to 2.96% TREO, and the Bankable Feasibility Study is over 70% complete. An Exploitation License was granted in August 2020, geochemical test reports have been approved by Greenland's Environment Agency for Mineral Resource Activities, and a $120 million letter of interest has been issued by the US Export-Import Bank. First ore production is targeted for late 2028 to early 2029.

Tanbreez operates a B2B sales-led go-to-market targeting defense contractors, clean energy and EV manufacturers, and advanced technology companies seeking to diversify rare earth supply away from Chinese dominance. Long-term offtake agreements cover 25% of projected production with REalloys Inc. (15%, supplying defense-grade metals under US DoD contracts) and Ucore Rare Metals Inc. (10%, focused on rare earth separation and processing). Distribution is enabled by year-round direct shipping access via deep water fjords to the North Atlantic Ocean. Capital sources include a $50 million PIPE financing in 2025, a $30 million acceleration program, the EXIM Bank LOI, and staged acquisition consideration via CRML share issuance.

Core offering

Tanbreez is developing a large-scale hard rock rare earth mining and concentration project in Southern Greenland based on a 4.7 billion tonne resource containing 28.2 million tonnes of Total Rare Earth Oxide (TREO) and over 27% heavy rare earth content. The project is designed to produce rare earth concentrates together with co-products including zirconium, tantalum, niobium, and hafnium for downstream separation and processing serving defense, clean energy, and advanced technology manufacturers. The asset is fully permitted under a granted Exploitation License and benefits from year-round deep-water fjord shipping.

Product overview

Tanbreez is a fully-permitted, globally significant rare earth mining project in Southern Greenland, operated as a subsidiary of Critical Metals Corp. The project centers on the Tanbreez Rare Earth Mine, which processes ore from a 4.7 billion-ton Kakortokite deposit covering an 8x5 km area to produce Rare Earth Concentrate containing both light and heavy rare earth oxides (with over 27% heavy rare earth content). The project has secured exploitation licensing from the Greenland Government and strategic offtake agreements covering 25% of projected production with REalloys Inc. and Ucore Rare Metals Inc.
