***HoA Amendment***

On September 29, 2025, Critical Metals Corp. (the "Company") entered into Amendment No. 1 to the Amended and Restated Heads of Agreement (the "HoA Amendment") with Rimbal Pty. Ltd. ("Rimbal"). The HoA Amendment amends the Amended and Restated Heads of Agreement, dated as of July 19, 2024 between the Company and Rimbal, which is the agreement that sets forth the terms by which the Company can acquire an up to 92.5% ownership interest in the Tanbreez Green Rare Earth Mine ("Tanbreez"). The HoA Amendment, among other things, (i) removes the Company's obligation to invest $10 million in Tanbreez to increase its ownership stake in Tanbreez to 92.5% and (ii) upon approval from the Greenlandic Mineral Resources Authority of Rimbal's transfer of Tanbreez to the Company, obligates the Company to increase its ownership in Tanbreez from 42% to 92.5% in exchange for the issuance of 14,500,000 ordinary shares, par value $0.001 per share, of the Company ("Ordinary Shares") to Rimbal. The remaining 7.5% ownership interest in Tanbreez is currently held by the Company's largest shareholder, European Lithium Limited.

The transaction remains subject to Greenland governmental approval. When issued at the closing, the Ordinary Shares will be issued in a private placement upon an exemption from the registration requirements of the Securities Act, pursuant to Section 4(a)(2) thereof.

On September 29, 2025, the Company published a press release, a copy of which is furnished as Exhibit 99.1 to this Form 6-K, relating to the HoA Amendment.

## Exhibit 99.1

**Exhibit 99.1**

**Critical Metals Corp Amends Agreement to Acquire a Controlling Interest in Tanbreez** 

 

**New York, NY** – September 29, 2025 – Critical Metals Corp. (Nasdaq: CRML) ("Critical Metals Corp" or the "Company"), a leading critical minerals mining company, today announced that it has amended its agreement to acquire the Tanbreez Greenland Rare Earth Mine (the "Tanbreez Project") from Rimbal Pty Ltd. ("Rimbal"), a company controlled by geologist and project founder Gregory Barnes.

Under the terms of the amended agreement, Critical Metals Corp now has the right to increase its ownership stake in the Tanbreez Project from 42% to 92.5% upon the issuance of approximately 14.5 million ordinary shares of the Company to Rimbal. Under the original agreement, the consideration for this increase in ownership was an unspecified number of shares of Critical Metals Corp with a value of $116 million determined at the time of the increase. The amended agreement revises the original agreement to provide a firm number of shares (14.5 million ordinary shares) to be issued to Rimbal at the closing, which implies a value of $8.00 per Critical Metals Corp ordinary share.

The transaction remains subject to Greenland governmental approval.

In addition to the change described above, Rimbal agreed to waive the previous condition that required Critical Metals Corp to invest an additional $10 million before qualifying for the increased ownership stake. Under the amended agreement, Critical Metals Corp is required to consummate the increase in ownership, including issuing the 14.5 million shares described above, promptly upon receipt of Greenland governmental approval of the transaction.

European Lithium will continue to maintain its 7.5% minority interest in the Tanbreez Project.

"This significant milestone agreement with Mr. Greg Barnes and Rimbal positions us to be laser focused on bringing this world-class asset into production," said Tony Sage, CEO and Executive Chairman of Critical Metals Corp. "With Greg remaining as a significant shareholder aligned with our long-term success, we look forward to continuing to leverage his deep technical expertise and decades of project knowledge as we advance our development strategy."

"Tanbreez is a game-changer for the rare earths supply chain in the West, with a significant concentration of high-grade heavy rare-earth elements and gallium contained within the 4.7 billion metric ton resource," said Mr. Barnes. "After working closely with Tony and the top-notch technical team at Critical Metals Corp over the past several months, I am confident in their ability to execute the commercialization roadmap and capitalize on the opportunities ahead. I remain committed to the project's success as both a shareholder and technical advisor."
