Rare earth miner Critical Metals (CRML) saw its share price close up 22.6% on Friday, August 21, 2026. The gain came after the company’s chief executive officer confirmed that the timeline for advancing its key asset, the Tanbreez project in Greenland, remains unchanged and is currently proceeding as planned.
The Tanbreez project is expected to begin producing rare earth elements within three years. These strategic metals are critical raw materials for manufacturing high-power magnets used in electric vehicles and defense equipment. Separately, Critical Metals disclosed financial details regarding its acquisition of European Lithium. Upon completion of the transaction, Critical Metals’ control over Tanbreez will increase from the current 92.5% to 100%. To mitigate the dilutive effect of this transaction on equity, the company has formulated corresponding measures aimed at stabilizing investor expectations, and this series of actions provided support to the stock price on that day. The Tanbreez deposit is rich in heavy rare earth elements used in high-performance magnets, which are widely applied in electronics, electric vehicles, and military systems, giving it strategic value far exceeding that of relatively cheap and abundant light rare earths.
Rare earth elements, especially heavy rare earths, are in scarce supply globally. Given their irreplaceability in defense applications, increasing domestic production of such minerals has become a priority for the U.S. government. Although officials have already invested in certain rare earth miners, and the market anticipates that Critical Metals may receive similar support, this remains market speculation and should not be used as the sole basis for investment decisions. It should be noted that the company currently has virtually no revenue and remains approximately three years away from formal production commencement. Rare earth mining is a capital-intensive industry, and the company still has a long way to go before achieving profitability.
Within the global supply chain landscape, China accounts for nearly 70% of global rare earth mining and 90% of processing capacity. In 2025, 67% of U.S. rare earth consumption relied on imports, with the majority originating from China. Against this backdrop, the Trump administration is vigorously promoting domestic supply of critical minerals, making the Tanbreez project a closely watched strategic asset. The market had previously been awaiting the project’s development permit, and the approval news in April of this year directly triggered a sharp surge in the share price.
