Critical Metals Corp shares jumped nearly 10% in premarket trading on January 20, 2026, driven by renewed U.S. tariff threats against European nations and heightened debate over Greenland’s strategic mineral deposits. President Trump’s announcement of a phased 10% to 25% tariff on eight European countries, contingent on securing Greenland for U.S. interests, refocused investor attention on rare earth supply chains. Market participants cited Greenland’s importance to defense and clean-energy technologies as the catalyst for the stock’s extended-hours rally.

Last week, Critical Metals unveiled a non-binding term sheet with Saudi Arabia’s Tariq Abdel Hadi Abdullah Al-Qahtani & Brothers to form a 50/50 joint venture. Under the proposal, the venture would refine one quarter of production from the Tanbreez project in southern Greenland at Saudi facilities before shipping intermediate product to the United States for final processing. Management believes this arrangement could de-risk logistics, accelerate downstream integration and enhance offtake discussions with U.S. defense contractors.

Investors are eyeing a management webcast scheduled for January 22 at 8:00 a.m. ET, where executives will discuss progress on project financing, environmental permitting and detailed development timelines for Tanbreez. While the company has secured initial support from financiers, no definitive funding commitments have been announced. Additional uncertainties include the non-binding nature of the Saudi term sheet and a recent Form 144 filing indicating planned insider stock sales. With a current market capitalization of approximately $2.08 billion and a year-to-date return exceeding 150%, the webcast could prove pivotal for setting near-term expectations.
