Proposed acquisition of Cygnus Metals Limited by Central Asia Metals PLC for A$232 million

Transaction highlights

• Central Asia Metals PLC (‘CAML’) to acquire Cygnus Metals Limited (‘Cygnus’) via Australian scheme

of arrangement, offering 0.06 New CAML Shares per Cygnus share, implying an equity value of

Cygnus of ~A$232 million1

• Transaction adds the Chibougamau Project in Québec, Canada (the ‘ Chibougamau Project ’), a

flagship high-grade copper-gold development asset in a high-quality jurisdiction, to CAML’s portfolio

of producing operations

• Transaction enhances scale, commodity and geographic diversification of CAML, combining cash -

generative assets and long-term exploration potential with a near-term development growth

pipeline

• CAML’s strong balance sheet provides a clear funding pathway to advance the Chibougamau Project,

and to de-risk its development, supported by CAML’s technical capabilities as a proven operator

• All-scrip transaction delivers premium for Cygnus shareholders while retaining upside exposure to

the Chibougamau Project

• Major shareholders of Cygnus, which together currently own and/or control in aggregate

approximately 29% of Cygnus Shares on issue have confirmed their intention to vote their respective

Cygnus Shares in favour of the Scheme at the Scheme Meeting subject to the qualifications

referenced in this announcement2

Central Asia Metals P LC (AIM: CAML) and Cygnus Metals Limited (ASX: CY5 , TSXV: CYG , OTCQB: CYGGF ) are

pleased to announce that they have entered into a definitive Scheme Implementation Deed (‘SID’) under which

CAML has agreed to acquire 100% of the fully paid ordinary shares in Cygnus ( ‘Cygnus Shares’) with each Cygnus

1 The terms of the Scheme value each Cygnus Share at A $0.176 per Cygnus Share based on the closing price of £ 1.56 per CAML share and a A$:£ exchange rate of A$1 :£0.53 on 1 June 2026. The Scheme

Consideration is based on 1,220,913,340 Cygnus Shares on issue , 1,050,000 Cygnus Shares to be issued as Stage 4 consideration for acquisition of the Beryl and Sakami projects , along with 83,621,706

Cygnus performance rights, 3,146,535 Cygnus share rights and 11,094,785 Cygnus options. For the purposes of calculating the implied equity value of the Scheme Consideration, all performance rights and

share rights are assumed to convert into ordinary shares and all outstanding in-the-money options are assumed to be exercised prior to the Record Date.

shareholders who have provided them.

shareholder being entitled to receive 0.06 new CAML shares for each Cygnus Share held at the prescribed record

date ( ‘New CAML Shares ’). The transaction, as contemplated in the SID, will be implemented by way of an

Australian Court-approved scheme of arrangement pursuant to Part 5.1 of Australia's Corporations Act 2001

(Cth) (‘Corporations Act’) ( ‘Scheme’).

The terms of the Scheme value each Cygnus S hare at A$0.176 per Cygnus Share based on the closing price of

£1.56 per CAML share and a A$:£ exchange rate of A$1 :£0.53 on 1 June 2026 (‘Scheme Consideration’). The

Scheme Consideration values the fully diluted share capital of Cygnus at A$232 million3.

Immediately following implementation of the Scheme, it is expected that existing CAML shareholders will own

approximately 70%, and Cygnus shareholders will own approximately 30%, of CAML’s enlarged fully diluted

issued share capital4.

The acquisition of Cygnus will add a flagship development -stage asset through a 100% interest in the

Chibougamau Copper-Gold Project, a high-grade deposit located in Québec, Canada to CAML’s existing portfolio

of producing and cash -flow generative assets located in North Macedonia and Kazakhstan and its exploration

projects. The latest Mineral Resource Estimate (‘MRE’) published by Cygnus in late 2025 for the Chibougamau

Project is 6.4 million tonnes at a 2.3% copper grade (‘Cu’), 0.8g/t gold grade (‘Au’) and 7.6g/t silver grade (‘Ag’)

in the Measured and Indicated Resource categories and 8.5 million tonnes at a 2.1% Cu grade, 1.7g/t Au grade

and 7.9g/t Ag grade in the Inferred Resource category5.

Cygnus shareholders will be asked to approve the Scheme at a scheme meeting (‘ Scheme Meeting’) which is

expected to be held in September 2026, with implementation of the Scheme to occur shortly thereafter. For the

Scheme to proceed, it must be approved by at least 75% of all votes cast by Cygnus shareholders and a majority

of Cygnus shareholders present and voting (in person or by proxy) at the Scheme Meeting, and the Scheme will

also require approval by a simple majority of the votes cast by Cygnus shareholders, excluding the votes of

certain related parties as prescribed by Canadian securities regulation Multilateral Instrument 61 -101 –

Protection of Minority Security Holders in Special Transactions, at the Scheme Meeting.

Prior to the Scheme Meeting, CAML will also convene a shareholder meeting to approve the allotment of the

New CAML Shares and grant of the New CAML Options (as defined below) (‘CAML Meeting ’). The CAML

shareholder resolution required will be duly-passed by a simple majority of those CAML shareholders who vote.

Under the SID, CAML has agreed to use all reasonable endeavours to apply for approval for listing its ordinary

shares on the Toronto Stock Exchange (‘ TSX’) or TSX Venture Exchange (‘TSXV’ and, together with the TSX, a

‘Recognised Canadian Exchange ’) prior to implementation of the Scheme, to provide holders of New CAML

Shares the ability to trade on the TSX or TSXV and to broaden CAML’s investor base in North America. Any such

listing will be subject to the satisfaction of the Recognised Canadian Exchange’s applicable listing requirements

and the receipt of all relevant regulatory approvals. For the avoidance of doubt, the proposed listing will have

no effect on CAML’s quotation on the AIM market of the London Stock Exchange, including its compliance with

the relevant continuing admission re quirements. There can be no certainty that a listing on a Recogn ised

Canadian Exchange will be achieved, or as to the timing thereof, and CAML will make further announcements

as appropriate.

Transaction highlights and rationale for Cygnus shareholders

• Immediate value realisation for Cygnus shareholders

o 60% premium to Cygnus’ last closing price on 1 June 2026 of A$0.11 per Cygnus Share

3 Refer footnote 1.

4 Based on 79 million New CAML Share s having been issued to Cygnus shareholders under the terms of the proposed Scheme. For the purposes of calculating the fully diluted issued share capital , all

performance rights and share rights of Cygnus are assumed to convert into ordinary shares and all outstanding in-the-money options of Cygnus are assumed to be exercised prior to the Record Date.

5 Refer to Cygnus’ ASX announcement titled ‘Cygnus reports a 78% increase in M&I resource at its Chibougamau Copper-Gold Project’ dated September 17, 2025.

o 49% premium to Cygnus’ 20 -day volume weighted average price (‘ VWAP’) to 1 June 2026 of

A$0.12 per Cygnus Share

• Provides exposure to strong balance sheet and cash generating business that de-risks development of

the Chibougamau Project

o The Scheme provides exposure to CAML’s robust and sustainable cash flow with CAML reporting

free cash flow of US$56 million in FY2025 and with existing analyst forecasts indicating a

substantial improvement in free cash flow in FY2026

o CAML has continually demonstrated its ability to return capital to shareholders, with FY2025 full

year dividends of 12 pence per share declared (US$28 million in total)

o Free cash flow to be used in part to fund advancement of the Chibougamau Project

• Commodity and project diversification, whilst retaining upside exposure to the Chibougamau Project

o Immediate exposure to CAML’s producing assets reduces exposure to risks associated with

potential development of a single asset operation and further diversifies commodity and

jurisdictional exposure

o 2026 production guidance for CAML of 12,000-13,000 tonnes of copper cathode, 18,000-20,000

tonnes of zinc-in-concentrate and 26,000-28,000 tonnes of lead-in-concentrate6

o Scrip consideration preserves Cygnus shareholders’ exposure to upside at Chibougamau as

exploration and development progresses, supported by CAML’s stronger balance sheet, while

reducing funding requirements and mitigating future dilution risk

• Increased trading liquidity in a diversified AIM50 quoted vehicle

o CAML’s shares are quoted on the AIM market of the LSE and are included in the FTSE AIM UK 50

and 100 indices

o Cygnus shareholders to be exposed to increased liquidity, with one-month Average Daily Traded

Value for CAML of ~A$2.0 million compared with Cygnus of ~A$0.2 million

o CAML to use all reasonable endeavours to apply for approval for listing its ordinary shares on a

Recognised Canadian Exchange

• CAML management team has extensive project development and operational experience

o Cygnus shareholders expected to benefit from CAML’s proven project development and

operational expertise particularly in base metals, underground mining, processing and dry stack

tailings

o CAML’s team has a strong track record and reputation in environmental, social and governance

matters, placing importance on developing and maintaining firm local relationships in its areas

of current operation

Transaction highlights and rationale for CAML shareholders

• Transformative acquisition

o Once in production, the Chibougamau Project has the potential to add meaningfully to CAML’s

annual copper-equivalent output and cash flows

o The acquisition a dds material near- term growth to CAML’s portfolio, with a flagship

development-stage copper -gold asset to complement existing operations, and additional

resource upside potential from ongoing exploration at and around the Chibougamau deposits

• High-grade development project with significant exploration potential

o High-grade copper-gold project with an MRE of 6.4 million tonnes at a 2.3% Cu grade, 0.8g/t Au

grade and 7.6g/t Ag grade in the Measured and Indicated Resource categor ies and 8.5 million

tonnes at a 2.1% Cu grade, 1.7g/t Au grade and 7.9g/t Ag grade in the Inferred Resource

category7

‒ This equates to 149 ,000 tonnes of contained copper and 167 ,000 ounces of gold in

M&I resources (with a further 182,000 tonnes of copper and 454,000 ounces of gold

in Inferred) underpinning the scale and quality of the asset

o The presence of an historical 900,000 tonnes per annum processing plant on site is expected to

provide a significant head start and lower capital requirements for the project once refurbished

o Updated PEA study* is already under way and would be completed by CAML

• Increased copper exposure in a tier-one jurisdiction

o Québec, Canada, is a world-class mining jurisdiction known for stable and supportive policies, a

highly skilled workforce and abundant low-cost hydroelectric power

o Canada’s federal Critical Minerals Infrastructure Fund has approved co -funding for feasibility

studies on transport and power infrastructure linking the Chibougamau deposits to the central

processing facility, underscoring Québec’s commitment to enabling new copper production

o The acquisition of Cygnus would broaden CAML’s geographical footprint beyond Kazakhstan and

North Macedonia, enhancing portfolio diversification

• Clear pathway to project development

o Baseline environmental and engineering studies for the Chibougamau Project have commenced,

and the project will be progressing through the permitting process in parallel with ongoing

resource drilling and advanced study work

o CAML will leverage its mine development expertise to complete an updated PEA* and progress

further feasibility studies in due course leading to project development

*Preliminary Economic Assessment (‘PEA’)

The outcomes of the PEA were first announced by Doré Copper Mining Corp. on 10 May 2022 and the

comprehensive technical report underpinning the PEA was announced by Doré in accordance with the

requirements of NI 43-101 on 15 June 2022 (‘2022 Technical Report’). The 2022 Technical Report was prepared

by BBA Inc. with several consulting firms contributing to sections of the study, including SLR, SRK Consulting

(Canada) Inc. and WSP Inc. The 2022 Technical Report and the announcement are available on SEDAR.

Cygnus cautions that the PEA is a preliminary technical, conceptual and economic study undertaken by Doré

of the initial evaluation and potential development of the Chibougamau Project. It is at scoping study level

only, which is based on a lower level of technical assessment that is not sufficient to support the estimation

of Ore Reserves and is inherently uncertain. The production targets and forecast financial information

disclosed in the PEA are underpinned by Measured Mineral Resources (approximately 1 .17%), Indicated

Mineral Resources (approximately 32.10%) and Inferred Mineral Resources (approximately 66.73%). However,

Cygnus is not able to disclose the outcomes of the PEA as the significant proportion of Inferred Resources

included in the l ife of mine means that pursuant to ASX and ASIC guidance there is not considered to be

sufficiently reasonable grounds for the production targets and forecast financial information disclosed in the

PEA. Accordingly, Cygnus is not disclosing the production targets and forecast financial information reported

in the PEA and cautions investors against making investment decisions based on such targets and forecasts.

Commenting on the Scheme, Nick Clarke, CAML’s Non-Executive Chairman, said:

“We see this transaction as a compelling opportunity for CAML to add a high -grade copper-gold asset that fits

well alongside our existing operations. Bringing the Chibougamau Project into the portfolio provides a clear

pathway to near -term growth, with the potential to make a meaningful contribution to production and cash

flow. The Scheme is consistent with our disciplined approach to pursuing acquisitions that enhance long- term

cash generation.”

Commenting on the Scheme, Gavin Ferrar, CAML’s Chief Executive Officer, said:

“The addition of this high ‑grade copper ‑gold project in a tier‑ one jurisdiction represents a material step to

strengthening our portfolio. We have been impressed by the quality and experience of the Cygnus team and

look forward to working closely with them to integrate the Chibougamau Project, complete an updated PEA and

advance the asset toward s a feasibility study. We also look forward to working in collaboration with our host

communities and other key stakeholders, including the Oujé-Bougoumou Cree Nation, the City of Chibougamau

and the Government of Québec.”

Commenting on the Scheme, David Southam, Cygnus’ Executive Chairman, said:

“This transaction is a true win -win outcome for both sets of shareholders. Cygnus shareholders can maintain

their exposure to the Chibougamau Project while reap ing the benefits of a highly respected base metals

operating company that produces free cash flow and pays dividends. These strengths are expected to mitigate

for existing shareholders certain future financial burdens associated with project development. CAML has all the

necessary experience in underground mining, processing, dry stack tailings and co ncentrate production to

deliver the Chibougamau Project. Importantly, CAML has a strong social licence in its current operations and we

expect them to be an excellent partner for our local communities and other stakeholders.”

Scheme structure and certain terms of the SID

Under the SID, CAML will acquire 100% of the Cygnus Shares by way of the Scheme, pursuant to which Cygnus

shareholders will receive 0.06 New CAML Shares per Cygnus Share held.

Implementation of the Scheme is subject to customary and other conditions, including (among other things):

• Receipt of specified North Macedonian and Kazakhstan regulatory approvals;

• An independent expert concluding and continuing to conclude that the Scheme is in the best interest of

Cygnus’ shareholders;

• Approval of the Scheme by Cygnus’ shareholders in accordance with Australia’s Corporations Act and

applicable Canadian securities laws at the Scheme Meeting;

• An ordinary resolution of CAML’s shareholders authorising the Directors to issue the New CAML Shares

pursuant to the Scheme and grant the New CAML Options (as defined below), as required by the

Companies Act 2006 of England and Wales;

• No Cygnus or CAML material adverse change, prescribed occurrence or regulated event arising (each as

defined in the SID); and

• Requisite Australian Court approvals.

In addition, the SID contains customary exclusivity provisions, including no shop, no talk and no due diligence ,

and a notification obligation and a matching right in favour of CAML. The SID also contains reciprocal break fee

provisions. The amount of the break fee, should it become payable, is approximately A$ 2.3 million. A copy of

the SID is attached to this announcement.

As part of the Scheme and subject to any required regulatory approvals, CAML intends to establish a share sale

facility to give smaller Cygnus shareholders the ability to have their CAML shares sold following implementation

of the Scheme. Cygnus shareholders (other than ineligible foreign shareholders) holding 85,176 or less Cygnus

Shares as at the record date for the Scheme will be able to elect to have the New CAML Shares they would have

otherwise received under the Scheme sold on their behalf, following implementation of the Scheme, by a third-

party broker through the share sale facility (‘Sale Facility’).

If CAML obtains approval for a listing of its ordinary shares on a Recognised Canadian Exchange, eligible Cygnus

shareholders, being those Cygnus shareholders who do not participate in the Sale Facility and who have a

registered address in Australia, Canada, New Zealand, Singapore, the United Kingdom or the United States of

America (‘Eligible Cygnus Shareholders’), will be entitled to elect to have their New CAML Shares to be tradable

on AIM or a Recogn ised Canadian Exchange (‘Exchange Election’). In the event an Eligible Cygnus Shareholder

makes a valid election for their New CAML Shares to be tradable on a Recogn ised Canadian Exchange and

approval for the New CAML Shares to be listed on a Recogn ised Canadian Exchange is not obtained, they will

receive their New CAML Shares that can be tradable on the AIM.

Eligible Cygnus Shareholders who do not make a valid election prior to the election cut-off date will be deemed

to have elected to receive their New CAML Shares that can be tradable on the AIM.

Further details on how Cygnus shareholders may participate in the Sale Facility and Exchange Election (as

applicable) will be included in the Scheme Booklet to be issued by Cygnus.

8

As a condition precedent to the Scheme, before the Court hearing to approve the Scheme, each holder of

options in Cygnus (a ‘ Cygnus Optionholder’) must have either (i) exercised their options in Cygnus ( ‘Cygnus

Options’) and received Cygnus Shares; (ii) entered into an agreement under which all of their Cygnus Options

will be automatically exercised upon the Scheme becoming effective; or (iii) agreed, to the extent their options

are not exercised before the Scheme record date, to their Cygnus Options being transferred to CAML or

cancelled in exchange for replacement options over the ordinary share capital of CAML on terms substantially

equivalent to the Cygnus Option it replaces (‘New CAML Options’).

Subject to the Scheme becoming effective and normal regulatory conditions, it is CAML’s intention to appoint a

current director of Cygnus to the CAML Board to support continuity of management of the Chibougamau Project.

It is also CAML’s intention to retain all Canada- based employees of Cygnus following implementation of the

Scheme.

Subject to Australian Court approval, Cygnus intends to distribute an explanatory statement to its shareholders

(‘Scheme Booklet’) containing information in relation to the Scheme, including the basis for the Cygnus Board’s

unanimous recommendation , an independent expert’s report providing an assessment as to whether the

Scheme is in the best interest of Cygnus shareholders, and other matters relevant to C ygnus shareholders,

indicatively around mid-August 2026.

The Scheme Meeting of Cygnus shareholders to approve the Scheme is expected to be held in mid -September

2026. Subject to the conditions of the Scheme being satisfied or waived (as applicable), the Scheme is expected

to be implemented in September 2026.9

CAML will be publishing a circular to its shareholders containing a notice of extraordinary general meeting in

due course at which it will propose the ordinary resolution described above.

CAML and Cygnus will keep the market informed of any material developments in accordance with their

respective disclosure obligations.
