TANTALEX LITHIUM ANNOUNCES CLOSING OF ITS PRIVATE PLACEMENT AND PROVIDES EARLY WARNING DISCLOSURE

Toronto, Ontario, November 18, 2025 - Tantalex Lithium Resources Corp. (CSE: TTX - FSE: DW8) ("Tantalex" or the "Corporation") is pleased to announce that further to its news release dated September 23, 2025, it has closed its previously announced non-brokered private placement of 126,315,000 common shares (the "Common Shares") at a price of $0.015 per Common Share for aggregate gross proceeds of $1,894,725 (US$1,350,000) (the "Private Placement"). The Private Placement was completed pursuant to a partial revocation order (the "Partial Revocation Order") of the Ontario Securities Commission dated September 19, 2025, partially revoking the failure to file cease trade order (the "FFCTO") issued against the Corporation.

The Corporation intends to use the net proceeds from the Private Placement to prepare and file outstanding financial statements and continuous disclosure records, partially pay outstanding related fees and penalties, meet certain financial obligations and to continue operations until it can apply for and receive a full revocation of the FFCTO. When the Corporation has filed all such outstanding financial statements and continuous disclosure records, the Corporation intends to apply for a full revocation of the FFCTO and ask that trading of its Common Shares on the Exchange be reinstated.

In accordance with applicable securities legislation and Canadian Securities Exchange (the "Exchange") policies, the Common Shares will be subject to a hold period of four months and a day from the closing date. All of the Corporation's Common Shares will remain subject to the FFCTO until such order is fully revoked. The granting of the Partial Revocation Order does not guarantee the issuance of a full revocation order in the future. The Corporation may apply for future partial revocation orders as necessary to continue operations. The Corporation did not pay any finders fees in connection with the completion of the Private Placement.

This Private Placement transaction constitutes a "related party transaction" under Multilateral Instrument 61-101 Protection of Minority Security Holders in Special Transactions ("MI 61-101"), as Mr. Simon Collins purchased Common Shares. Pursuant to MI 61-101, the Corporation will file a material change report providing disclosure in relation to each "related party transaction" on SEDAR+ under the Corporation's issuer profile at www.sedarplus.ca. The Corporation did not file the material change report more than 21 days before the expected closing date of the Private Placement as the details of the Private Placement were not settled until shortly prior to the conclusion of the Private Placement, and the Corporation wished to complete the Private Placement on an expedited basis for sound business reasons and compliance with the Partial Revocation Order deadline. The Corporation is relying on exemptions from the formal valuation and minority shareholder approval requirements available under MI 61-101. The Corporation is exempt from the formal valuation requirement in section 5.4 of MI 61-101 in reliance on sections 5.5(a) and (b) of MI 61-101 as the fair market value of the transaction, insofar as it involves each Mr. Collins, is not more than 25% of the Corporation's market capitalization (based on the last previous closing price while the Corporation was still actively trading). Additionally, the Corporation is exempt from minority shareholder approval requirement in section 5.6 of MI 61-101 in reliance on section 5.7(1)(a) as the fair market value of the transaction, insofar as it involves each of Mr. Collins, is not more than 25% of the Corporation's market capitalization. The Private Placement was previously approved by the board of directors of the Corporation, including disinterested directors. No special committee was established in connection with the transaction, and no materially contrary view was expressed or made by any director.

The completion of the Private Placement remains subject to the receipt of all requisite approvals, including the final acceptance of the Exchange.

The securities being referred to in this news release have not been, nor will they be, registered under the United States (U.S.) Securities Act of 1933, as amended, and may not be offered or sold in the U.S. or to, or for the account or benefit of, U.S. persons absent registration or an applicable exemption from the registration requirements. This news release does not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of the securities in any jurisdiction in which such offer, solicitation or sale would be unlawful.
