Foremost Clean Energy Ltd.

This prospectus supplement amends and supplements the prospectus dated August 9, 2024, as supplemented or amended from time to time (the “Prospectus”), which forms a part of our Registration Statement on Form F-1 (Registration Statement No. 333-272028). This prospectus supplement is being filed to update and supplement the information included or incorporated by reference in the Prospectus with the information contained in our Report on Form 6-K, furnished to the Securities and Exchange Commission on December 3, 2024 (the “Form 6-K”). Accordingly, we have attached the Form 6-K to this prospectus supplement.

This prospectus supplement updates and supplements the information in the Prospectus and is not complete without, and may not be delivered or utilized except in combination with, the Prospectus, including any amendments or supplements thereto. This prospectus supplement should be read in conjunction with the Prospectus and if there is any inconsistency between the information in the Prospectus and this prospectus supplement, you should rely on the information in this prospectus supplement.

Our Common Shares and Common Share Purchase Warrants are listed on the Nasdaq Capital Market (“Nasdaq”) under the symbols “FMST” and “FMSTW”, respectively, and our Common Shares are listed on the Canadian Securities Exchange (the “CSE”) under the symbol “FAT”. On December 5, 2024, the last reported sales prices of the Common Shares on Nasdaq and the CSE were US$1.4050 and C$1.9200, respectively, and the last reported sales price of the Common Share Purchase Warrants on Nasdaq was US$0.2500.

We are an “emerging growth company,” as that term is used in the Jumpstart Our Business Startups Act of 2012, and as such, have elected to comply with certain reduced public company reporting requirements for this prospectus and future filings. See “Prospectus Summary-Implications of Being an Emerging Growth Company.”

Investing in our common shares involves a high degree of risk. See “Risk Factors” beginning on page 15 of the prospectus for a discussion of information that should be considered in connection with an investment in our common shares. Neither the U.S. Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.
