Critical Metals Corporation's stock plummeted 8.28% in post-market trading, following a significant rally earlier in the week.

The decline is attributed to profit-taking pressure after the stock surged 39.59% intraday on April 17, driven by the company's announcement that the Greenland government approved the transfer of the remaining 50.5% stake in Tanbreez Mining Greenland A/S. This raises Critical Metals' total ownership to 92.5%, granting it absolute control over the rare earth project and positioning it as a potential key node in the Western heavy rare earth supply chain. The U.S. Export-Import Bank has issued a letter of intent for up to $120 million in financing for the project.

Additionally, broader weakness in the Diversified Metals & Mining sector contributed to the pullback, with all top movers in the sector declining during the session.
