Central Asia Metals PLC (AIM, TSX: CAML) is pleased to announce that the scheme of arrangement pursuant to which CAML has agreed to acquire the entire issued share capital of Cygnus Metals Limited (‘Cygnus’) (the ‘Scheme’) has become effective and the acquisition of Cygnus has now completed.

Capitalised terms used but not otherwise defined in this announcement have the meanings given to them in the Company's announcement of 2 June 2026.

Completion of the Cygnus acquisition

Following implementation of the Scheme, Cygnus has become a wholly-owned subsidiary of CAML. The combination brings the Cygnus assets, including the Chibougamau copper-gold project, into the enlarged CAML Group.

Listing on the Toronto Stock Exchange

The Company is also pleased to confirm that its ordinary shares are listed on the Toronto Stock Exchange (the ‘TSX’) and will commence trading on the TSX effective at 09:30 (EST) (being, 13:30 (GMT)) today.

Issue of New CAML Shares and Admission

Under the Scheme, Cygnus Shareholders were entitled to receive 0.06 New CAML Shares (as defined below) for each Cygnus share held at the Scheme Record Date, subject to the arrangements applicable to participants in the Share Sale Facility.

Accordingly, pursuant to the terms of the Scheme, the Company has allotted, conditional only on admission of the same to trading on AIM ('Admission'), 78,474,252 new ordinary shares of US$0.01 each in the capital of the Company (the ‘New CAML Shares’) to those persons who were Cygnus Shareholders as at the Scheme Record Date as consideration for the acquisition of Cygnus.

Application for Admission has been made for the New CAML Shares and Admission is expected to become effective and dealings in the New CAML Shares to commence at 08:00 (GMT) today, 27 October 2026.

The New CAML Shares, on Admission, will rank pari passu in all respects with the Company's existing ordinary shares, including the right to receive all dividends.

Grant of replacement options

In accordance with the terms of the Scheme, CAML is required to grant replacement options to those persons who held options in Cygnus as at the Scheme Record Date. Accordingly, CAML has today granted options over an aggregate of 649,913 ordinary shares in the Company (the ‘CAML Options’) pursuant to individual option replacement deeds (the ‘Option Replacement Deeds’).

The CAML Options replace the corresponding options over ordinary shares in Cygnus, which were cancelled with effect from the Implementation Date.  Each CAML Option entitles the holder to acquire one Ordinary Share in the Company and has been granted on the equivalent terms set out in the relevant Option Replacement Deed.

Summary terms of the CAML Options granted are set out below:

Total voting rights

Accordingly, the total number of voting rights in the Company following Admission is 256,185,208. This figure may be used by shareholders as the denominator for the calculations by which they determine whether they are required to notify their interest in, or a change to their interest in, the Company under the Financial Conduct Authority's Disclosure Guidance and Transparency Rules.
