Rare earth developer Critical Metals has approved the construction of a multi-use storage and pilot facility in Qaqortoq, Greenland, a move that sent its shares sharply higher on Wednesday. The new infrastructure is intended to support the company’s flagship Tanbreez project as it moves toward development.
The company said the facility will be delivered under a full turnkey contract covering engineering, permitting, logistics, construction and commissioning. Designed specifically for Arctic conditions, the site is expected to be completed and operational by May 2026. In parallel, Critical Metals has acquired a residential property in Qaqortoq, which will be converted into a permanent local office and operational base.
Chief executive Tony Sage said the project provides a clear and structured pathway to deploy pilot-scale infrastructure in a challenging Arctic environment, while also demonstrating the company’s commitment to responsible local operations.
Investors reacted positively to the announcement, with Critical Metals’ stock rising as much as 16% to its highest level in more than two months, lifting the company’s market capitalization to around $1.5 billion.
The Tanbreez project is regarded as one of the world’s largest rare earth deposits, hosting at least 45 million tonnes of resources within a largely underexplored kakortokite unit. Earlier this year, Critical Metals published a preliminary economic assessment outlining a phased development plan, with initial annual production of about 85,000 tonnes of rare earth oxides, potentially scaling up to 425,000 tonnes following modular expansion. The company has already secured offtake agreements covering roughly three-quarters of expected output and aims to finalize the remainder in the near term.
