From Greenland to Romania: European Lithium's Ambitious Hafnium Push Meets a Funding Reality Check

The path to European Lithium’s merger with Critical Metals Corp is turning into a high-stakes balancing act. On one side, the company secured a critical logistical foothold in Greenland earlier this month, unlocking the Tanbreez rare-earth project that could more than double the world’s supply of hafnium. On the other, it faces a A$24 million cash shortfall that threatens to delay the deal — made harder by an exclusivity clause that prohibits raising new capital.

Greenland’s government gave the nod in early May for European Lithium to take a 70% stake in logistics provider 60° North Greenland, a company vital for transporting materials from the remote Tanbreez site. The pilot plant in Qaqortoq is already built, though operations remain on hold pending final regulatory sign-off. If that comes in time, a 150-tonne sample extraction is slated to start in June. But a separate snag in Austria — where the Federal Administrative Court overturned a key environmental permit for the Wolfsberg project — has pushed a final investment decision there to late 2026. The offtake agreement with BMW, however, remains intact.

The real game-changer, however, is hafnium. Critical Metals Corp, which is merging with European Lithium, now holds a 50.5% stake in Tanbreez — with an option to climb to 92.5%. From 2030, the mine is expected to produce 130,000 tonnes of concentrate annually, containing roughly 2,300 parts per million of hafnium. That concentrate would be sent to a planned joint refinery in Romania, designed to process 120 to 150 tonnes of hafnium per year. To put that in perspective, current global hafnium output stands at just 70 to 75 tonnes annually. The ambition is to slash western reliance on China, which controls three-quarters of the market.

Should investors sell immediately? Or is it worth buying European Lithium?

Hafnium’s appeal is far from niche. It is used in advanced semiconductors, jet engines, nuclear reactors, and AI chips. Global demand is forecast to jump 70% by 2030, with the semiconductor segment alone growing from roughly $420 million to $726 million — a 10% compound annual rate. High-purity hafnium (99.99%) fetches between $13 million and $15 million per tonne, and the market already faces a supply deficit of about 20 tonnes a year.

Yet the merger financing is tightening. As of March, European Lithium had A$306 million in cash — A$24 million short of the A$330 million needed to complete the deal. The exclusivity agreement with Critical Metals, extended on May 7 after the original deadline was missed, bars the company from raising debt or equity during negotiations. Management must close the gap using internal resources. A share buyback of up to A$12.6 million, plus operating cash flow, will be stretched to cover the difference.

The stock market is already showing strain. Morgan Stanley unloaded a large block of shares by April 30, dropping below the substantial holder threshold and exiting the register entirely. On the Australian exchange, European Lithium’s shares slipped to A$0.48 on Tuesday, down from the implied merger value of A$0.58 per share. The year-to-date performance still shows a gain of roughly 205%, but the discount reflects lingering uncertainty. Meanwhile, Critical Metals Corp closed on Nasdaq at $11.83, having surged 670% over the past 12 months despite a $153.3 million loss in its latest fiscal year.

European Lithium’s market capitalisation stands at around A$725 million. The next major milestone is the annual general meeting in the third quarter, where shareholders will vote on the buyback extension and assess progress on both the merger and the underlying projects. If the cash gap can be bridged and the Greenland logistics chain finalised, the company’s hafnium ambitions could turn it into a rare-earth powerhouse. But for now, the clock is ticking on two fronts at once.
