MKANGO ANNOUNCES ANNUAL GENERAL AND SPECIAL MEETING OF SHAREHOLDERS

London / Vancouver: May 15 2026 - Mkango Resources Ltd (AIM/TSX-V: MKA) (the "Company" or "Mkango"), announces that an annual general and special meeting (the "Meeting") of the holders of common shares ("Shareholders") of the Company will be held on June 5, 2026 to approve, amongst other matters, (i) amendments (the "Amendments") to the Company's amended and restated stock option plan, last approved by the Shareholders at the Company's last annual meeting held on November 12, 2025 (the "Plan"), (ii) the extension of the term of certain stock options, which were issued under the Plan to certain insiders of the Company, from 10 years to 15 years, and (iii) the waiver of oversight by the TSX Venture Exchange (the "TSXV") of actions proposed to be undertaken by Mkango Rare Earths Limited ("MKAR"), a wholly-owned subsidiary of the Company, following the completion of MKAR's proposed merger transaction with Crown Proptech Acquisitions and listing of the MKAR common shares on the Nasdaq Stock Market (the "Proposed MKAR Transaction").

Amendments to Mkango's Stock Option Plan and Extension of Vesting Period of Certain Options

The Plan currently requires that the maximum term of the options not exceed 10 years from the date of issue. Currently, 4,693,334 options, each with an exercise price of C$0.06, will expire on June 15, 2026 and 2,175,000 options, each with an exercise price of C$0.07, will expire on October 23, 2026 (collectively, the "Options"). The directors have amended the Plan to permit the Company, subject to disinterested Shareholder approval at the Meeting and the approval of the TSX-V, to extend the term of the Options to 15 years from the date of issue (the "Extension").

If the Amendments are not approved, the holders of the Options will be required to exercise the Options or let them lapse.

The reasons for requesting the approval of the Extension are included in the Company's management information circular dated May 4, 2026 (the "Circular") mailed today to Shareholders and available on the Company's website at mkango.ca/investors/annual-general-meeting/ and under the Company's profile on SEDAR+ at www.sedarplus.ca/home/. Shareholders are encouraged to read the Circular prior to voting on the resolution approving the new Option Plan containing the amendments permitting the Extension.

If approved by Shareholders, the Extension will constitute a "related party transaction" under Multilateral Instrument 61-101 - Protection of Minority Security Holders in Special Transactions ("MI 61-101"). The Extension will, however, be exempt from the valuation requirements in MI 61-101 under section 5.5(b) of MI 61-101. Whilst Mkango is seeking disinterested Shareholder approval for the Extension at the Meeting, this approval is not required as a result of the exemption provided in section 5.7(a) of MI 61-101.

Waiver of TSX-V Oversight over Activities of MKAR

The waiver of TSXV oversight over MKAR's future activities post the Proposed MKAR Transaction is being sought on the basis that on completion of the Proposed MKAR Transaction, MKAR is expected to be listed on Nasdaq and to become subject to ongoing regulation and oversight by both the U.S. Securities and Exchange Commission and Nasdaq. The Company believes that such regulation will be sufficient to protect the interests of the Company and its shareholders vis-à-vis its subsidiary MKAR and that additional regulation by the TSXV could result in delays that may adversely affect MKAR's operational flexibility. Additional information in respect of the Proposed MKAR Transaction and the approval being sought are included in the Circular, which Shareholders are encouraged to read before voting on the resolution in respect of the waiver.
