Shares of Critical Metals surged to their highest level in nearly three months after the company announced further upgrades to its flagship Tanbreez rare earth project in southern Greenland, amid renewed geopolitical attention on the Arctic territory from the United States.
Earlier this week, the Nasdaq-listed company said it will acquire a fully integrated, mobile assay laboratory to support its Tanbreez project, which hosts one of the world’s largest known rare earth deposits. The laboratory, developed by mining solutions provider Bromet, will enable real-time, on-site geochemical analysis of drill core and pilot plant samples, strengthening data collection and accelerating decision-making as the project advances toward pilot-scale operations.
Critical Metals CEO Tony Sage described the acquisition as a transformative step in moving Tanbreez from exploration into pre-mining development. The company is expected to pay around $1 million for the mobile laboratory. The move follows a recent decision to construct an Arctic-grade storage and pilot facility in Qaqortoq, scheduled for completion by mid-2026, and comes alongside potential logistics improvements linked to the planned opening of a new international airport near the project site.
The upgrades are part of a modular, turnkey development strategy aimed at fast-tracking Tanbreez into production as early as this year. A preliminary economic assessment released last year outlined an initial production target of approximately 85,000 tonnes of rare earth oxides per year, with potential expansion to 425,000 tonnes annually. The assessment estimated a pre-tax net present value of about $3 billion and an internal rate of return of 180%, based on resources of at least 45 million tonnes within the largely underexplored kakortokite unit.
Investor interest has also been boosted by rising geopolitical tensions surrounding Greenland. US President Donald Trump reiterated his desire for US control of Greenland this week, citing national security concerns, and senior US, Danish and Greenlandic officials held discussions in Washington on the issue. Analysts view Greenland’s vast untapped mineral resources, including rare earths, as a key driver behind Washington’s intensified interest.
Following the announcements and geopolitical developments, shares of Critical Metals jumped as much as 35% in New York trading, lifting the company’s market capitalization to around $2.1 billion.
