CORNISH METALS ANNOUNCES UPDATE TO ITS PLANS TO RE-DOMICILE TO THE UK

Vancouver, October 7, 2025

Cornish Metals Inc. (AIM/TSXV: CUSN) ("Cornish Metals", "Cornish Canada" or the "Company") is pleased to announce that, in connection with its previously announced intention to re-domicile from Canada to the UK, it has today entered into an arrangement agreement (the "Arrangement Agreement") with Cornish Metals plc ("Cornish UK") pursuant to which Cornish Canada will be re-domiciled to the UK (the "Re-Domicile" or the "Transaction"). Completion of the Re-Domicile shall be subject to certain conditions, including, inter alia, shareholder and regulatory approvals. It is expected that the Re-Domicile will be completed in December 2025.

As previously announced, in conjunction with the strategic investment by National Wealth Fund Limited ("NWF"), the Company provided an undertaking to NWF that it shall use all reasonable and commercially prudent endeavours to re-domicile the Company from Canada to the UK by no later than 24 March 2026. 

Following execution of the Arrangement Agreement, certain documents will be submitted to the Ontario Superior Court of Justice for an interim hearing on the proposed court-approved plan of arrangement ("Arrangement") scheduled for 14 October 2025 (the "Interim Hearing").  

Subject to the outcome of the Interim Hearing, further information will be circulated to shareholders ahead of the convening of a special meeting to approve the Arrangement which is anticipated to be held in the second half of November 2025.

Don Turvey, CEO and Director of Cornish Metals, stated: "Re-domiciling Cornish Metals from Canada to the UK simplifies the Company's structure and better aligns with our strategic and operational focus in the UK to restart tin production at our South Crofty mine in Cornwall. We expect to benefit from reduced regulatory, legal and other costs associated with the dual-listing, improved liquidity of the single quotation on AIM and reduced transaction and overall complexity, which is paramount as we advance the project finance process. We value our Canadian shareholders and hope that they will continue to support the Company on our journey towards becoming an important Western World tin producer."

Summary of re-domicile process

The Arrangement will be completed by all shareholders of the Company transferring all of the issued and outstanding common shares in the capital of Cornish Canada ("Cornish Canada Shares") to Cornish UK in exchange for the issue to them of new shares in Cornish UK ("Cornish UK Shares"), on the basis of one (1) Cornish UK Share for ten (10) Cornish Canada Shares, rounded down to the nearest whole number of Cornish UK Shares. In the event that any holder of Cornish Canada Shares holds fewer than ten (10) Cornish Canada Shares, or the number of Cornish Canada Shares held when divided by ten (10) is not a whole number, such allocation will be rounded down to the nearest whole number (or zero, if fewer than ten (10) Cornish Canada Shares are held immediately prior to the Effective Date (as defined below)).

The Arrangement will result in Cornish UK becoming the parent company of the Cornish Group (as defined in the Arrangement Agreement).

It is expected that rights attaching to the Cornish UK's shares held by the former holders of the Cornish Canada Shares ("Cornish Canada Shareholders") on completion of the Transaction will remain substantially the same. Accordingly, immediately upon the Arrangement becoming effective (the "Effective Date"), a Cornish Canada Shareholder will have the same proportionate interest in the profits, net assets and dividends of Cornish UK as they have in Cornish Canada immediately prior to the Effective Date.

Cornish UK will apply for admission to trading of its Cornish UK Shares on the AIM market of the London Stock Exchange ("AIM"). Cornish Canada intends to delist the Cornish Canada Shares from the TSX Venture Exchange (the "TSXV") and cancel the admission to trading of the Cornish Canada Shares on AIM. Cornish Canada also intends to apply to cease to be a reporting issuer in Canada following completion of the Re-Domicile.

Information for shareholders

The Company will send a management information circular (the "Circular") to the Cornish Canada Securityholders (as defined in the Arrangement Agreement), setting out the details of the Transaction and containing a notice of special meeting of Cornish Canada. The Circular will also outline the considerations of the board of directors of Cornish Canada (the "Board") with respect to its determination that the Transaction is in the best interests of Cornish Canada and the Cornish Canada Shareholders and its recommendation that all Cornish Canada Shareholders vote in favour of the Arrangement.

Special meeting for shareholders

At a special meeting of the Company (the "Special Meeting"), among other things, Cornish Canada Securityholders will be asked to approve the Re-Domicile and its implementation by way of a court-approved plan of arrangement pursuant to the terms and conditions of the Arrangement Agreement.

The Arrangement must be approved by not less than: (i) 66⅔% of the votes cast by Cornish Canada Shareholders present in person or represented by proxy and entitled to vote at the Special Meeting; (ii)  66⅔% of the votes cast by Cornish Canada Securityholders present in person or represented by proxy and entitled to vote, voting together as a single class, at the Special Meeting; and (iii) a simple majority of the votes cast on such resolution by Cornish Canada Shareholders present in person or represented by proxy and entitled to vote at the Special Meeting, other than the votes attached to the Cornish Canada Shares required to be excluded pursuant to Multilateral Instrument 61-101 - Protection of Minority Security Holders in Special Transactions. 66⅔% of the votes cast by Cornish Canada Shareholders at the Special Meeting will also fulfil the TSXV requirement to obtain the approval of a simple majority of Cornish Canada Shareholders. The Arrangement also requires, among other things, final approval of the Court.

Further information

Pursuant to the application for the admission of Cornish UK Shares to trading on AIM, Cornish UK will publish an AIM Schedule 1 announcement ("Schedule 1 Announcement") together with an Appendix to that announcement ("Appendix") which contains more information about the Re-Domicile and Cornish UK. The Circular and the Schedule 1 Announcement, together with the Appendix, will be made available for viewing on Cornish Canada's website at www.cornishmetals.com and on its SEDAR+ profile at www.sedarplus.ca.

The Company will provide further details related to the Transaction and other material information as it becomes available. The Transaction will be subject to, inter alia, the requisite approvals of Cornish Canada Securityholders, approval at the Special Meeting, the approval of the Court, and certain regulatory approvals, including approval from the TSXV.
