EXPLANATORY NOTE

Closing of Acquisition of Tanbreez Stage 2 Interest

As previously disclosed, Critical Metals Corp. (the “Company”) entered into an amended and restated Heads of Agreement (as amended, the “Heads of Agreement”) with Rimbal Pty. Ltd. (“Rimbal”) in July 2024, which was amended in September 2025. Pursuant to the Heads of Agreement, the Company held a 42% ownership interest in Tanbreez Mining Greenland A/S (“Tanbreez”) immediately prior to the Stage 2 Closing (as defined below). The Heads of Agreement provided that, upon approval from the Greenlandic Mineral Resources Authority (the “Greenland MRA”) of Rimbal’s transfer of Tanbreez to the Company, the Company was obligated to increase its ownership interest in Tanbreez from 42% to 92.5% (the “Stage 2 Interest”) 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.

On April 29, 2026, the Company and Rimbal completed the issuance of the Stage 2 Interest and the other closing procedures contained within the Heads of Agreement (the “Stage 2 Closing”). The Ordinary Shares were issued to Rimbal in a private placement exempt from the registration requirements of the Securities Act of 1933 (the “Securities Act”), in reliance on the exemptions set forth in Section 4(a)(2) of the Securities Act. The Company is obligated under the Heads of Agreement to file a registration statement for the resale of the Ordinary Shares issued to Rimbal.

On April 30, 2026, the company issued a press release announcing the Stage 2 Closing. A copy of the press release is furnished as Exhibit 99.1 herewith.
