London / Vancouver: 3 June 2025 - Mkango Resources Ltd (AIM/TSX-V: MKA) ("Mkango") is pleased to announce that its wholly-owned subsidiary, Lancaster Exploration Limited ("Lancaster"), has entered into a US$750,000 Note Purchase Agreement (the "NPA") with one sponsor (the "F-4 Note Investor") and an affiliate of the other sponsor (the "BCA Note Investor") of Crown PropTech Acquisitions, a Cayman Islands exempted company (OTC: CPTK) ("CPTK"), in connection with the previously announced (8 January 2025) proposed merger (the "Merger") between Lancaster, certain other wholly-owned subsidiaries of Mkango (with Lancaster, the "Company"), and CPTK.

The Merger would create a vertically integrated global pure play rare earths platform that is intended to result in the ordinary shares of Lancaster being listed on NASDAQ. Upon the Merger and listing, Lancaster, as the listed entity, would hold Mkango's rare earths project at Songwe Hill in Malawi and the proposed separation plant in Pulawy Poland. Mkango's interest in the HyProMag recycling business would not form part of the Merger.

Pursuant to the NPA, Lancaster has agreed to issue and sell two convertible promissory notes (together, the "Notes"), one to the BCA Note Investor in the principal amount of US$500,000 (the "BCA Note") and one to the F-4 Note Investor in the principal amount of US$250,000 (the "Form F-4 Note"), upon satisfaction of different sets of conditions. The BCA Note Investor has deposited US$500,000 into escrow, with its release to Lancaster pending the satisfaction of conditions including the execution of a definitive business combination agreement for the Merger (the "BCA") and approval by the TSX Venture Exchange ("TSX-V") of the potential conversion of the BCA Note into shares of Lancaster. Lancaster intends to return the escrowed funds to the BCA Note Investor if the BCA Note is not issued by 30 June 2025, which is the expiration date of exclusivity regarding the BCA and which may be extended. The Form F-4 Note is expected to be issued following the execution of the BCA and, subject to TSX-V approval of the potential conversion of the Form F-4 Note into shares of Lancaster, upon the submission of a registration statement on Form F-4 with the U.S. Securities and Exchange Commission ("SEC") covering the issuance of share consideration pursuant to the Merger.

Following issuance, the Notes will accrue interest at a rate of 12% per annum, 9% of which will be paid in kind, subject to conditional approval of the TSX-V, such that the Notes' principal amounts will be increased by the amount of such interest payments semi-annually, and 3% of which will be paid in cash semi-annually. The maturity date of the Notes is to be one year after their respective issuances.

If the Notes are outstanding at the time of the Merger, the principal and accrued and unpaid interest of the Notes will convert (the "Standard Conversion") into twice the number of shares to which such dollar amount would equate based on the implied dollar value of Company shares in the proposed BCA (the "Proposed BCA Valuation"). Alternatively, if CPTK satisfies certain cash thresholds at the time of the Merger, the BCA Note Investor and the F-4 Note Investor may opt to have any portion of such principal and interest repaid in cash as well as convert into half the number of shares to which such dollar amount would equate based on the Proposed BCA Valuation, with the balance of the Notes, if any, converting pursuant to the Standard Conversion.

If the Notes remain outstanding by their maturity dates, the BCA Note Investor and the F-4 Note Investor will be entitled to receive 1.2 times the original principal amount of the Notes in addition to any accrued and unpaid interest, less any principal amounts already paid as of the maturity date.

Information about the NPA will be provided in a Current Report on Form 8-K to be filed by CPTK with the SEC and is available at www.sec.gov.

Alexander Lemon, President of Mkango, commented: "This Note Purchase Agreement unlocks working capital to assist Lancaster in its NASDAQ listing whilst minimising dilution at the Mkango level. We're grateful for the continued support from CPTK and its sponsors and affiliates as we enter this exciting new phase for the Company and advance this transformative transaction for Mkango."

Michael Minnick, CEO of CPTK, added: "Our thesis for the rare earths sector continues to strengthen, particularly with the demonstrated growth in AI and the evolving robotics applications, amongst others. We believe the Mkango team is well-positioned in this sector based on their completed definitive feasibility study, environmental compliance, and signed mining development agreement with the government of Malawi."
