RECOMMENDED SHARE AND CASH OFFER

FOR

ADRIATIC METALS PLC

BY

DUNDEE PRECIOUS METALS INC.

to be effected by means of a scheme of arrangement

under Part 26 of the Companies Act 2006

SUMMARY

The Boards of Dundee Precious Metals Inc. (“ DPM”) and Adriatic Metals Plc (“ Adriatic”) are

pleased to announce that they have agreed the terms of a recommended acquisition of the

entire issued and to be issued ordinary share capital of Adriatic (the “Transaction”).

Key Terms

Under the terms of the Transaction, Adriatic Shareholders will be entitled to receive, for each

Adriatic Share:

0.1590 New DPM Share; and

93 pence in cash

The terms of the Transaction value:

 each Adriatic Share at 268 pence, based on a GBP:CAD$ exchange rate of 1.850 on

11 June 2025;

 each Adriatic CDI at AUD $5.56, based on a AUD:CAD$ exchange rate of 0.891 and

a GBP:AUD exchange rate of 2.077 on 11 June 2025; and

 the entire issued share capital of Adriatic at approximately US$1.251 billion, based

on USD:GBP exchange rate of 0.739 on 11 June 2025,

in all cases, based on the Closing Price of CAD$20.33 per DPM Share on 11 June 2025.

2

The terms of the Transaction represent a premium of approximately:

 50.5 per cent. to the Closing Price on the LSE of 178 pence per Adriatic Share on 19

May 2025 (being the last Business Day in London, England prior to the

commencement of the Offer Period); and

 47.8 per cent. to the Closing Price on the ASX of AUD $3.76 per Adriatic CDI on 20

May 2025 (being the last Business Day in Sydney, Australia prior to the

commencement of the Offer Period);

 31.8 per cent. to the 30-day volume-weighted average Adriatic share price on the

LSE as of 19 May 2025, based on the 30-day volume-weighted average share price

of DPM on the Toronto Stock Exchange (“ TSX”) as of 16 May 2025 (being the last

Business Day in Toronto, Canada prior to the commencement of the Offer Period);

and

 33.5 per cent. to the 30-day volume-weighted average Adriatic CDI price on the ASX

as of 20 May 2025 (being the last Business Day in Sydney, Australia prior to the

commencement of the Offer Period in Sydney, Australia), based on the 30-day

volume-weighted average share price of DPM on the TSX on 16 May 2025 (being the

last Business Day in Toronto, Canada prior to the commencement of the Offer

Period).

The Mix and Match Facility will also be made available to Adriatic Shareholders in order to

enable them to elect, subject to off-setting elections, to vary the proportions in which they

receive cash and New DPM Shares. The aggregate amount of cash to be paid and New DPM

Shares to be issued under the terms of the Transaction will be £321 million and 54.9 million

New DPM Shares, equating to 34.7 per cent cash and 65.3 per cent New DPM Shares, and will

not be varied as a result of the Mix and Match Facility.

Immediately following Completion, it is expected that DPM’s enlarged issued share capital will

be owned approximately 75.3 per cent. by existing DPM Shareholders and approximately 24.7

per cent. by former Adriatic Shareholders.

Holders of CHESS Depository Interests over Adriatic Shares (“ Adriatic CDIs”) will participate

in the Transaction on the same basis as holders of Adriatic Shares. Accordingly, unless the

context requires otherwise, references to Adriatic Shares in this Announcement include Adriatic

CDIs, references to Adriatic Shareholders include Adriatic CDI Holders, references to Adriatic

Shareholders voting on the Transaction, the Scheme or related matters shall include Adriatic

CDI Holders procuring the same.

DPM has received irrevocable undertakings to vote in favour of the Scheme and the Adriatic

Resolutions from certain Adriatic Directors who are interested in Adriatic Shares and Supporting

non-director Shareholders, including Helikon Investments Limited and L1 Capital Pty Ltd, who

hold a total of 128,541,045 Adriatic Shares in aggregate, representing 37.23 per cent. of

Adriatic’s total issued share capital on the Last Practicable Date.

Background to and reasons for the Transaction

The acquisition of Adriatic has compelling strategic merit and is fully aligned with DPM’s core

competencies. DPM believes that the Transaction will form a strong combined group with an

enhanced operating and financial profile, driven by an attractive production, mineral reserve

and mineral resource base and a compelling metal mix. The Transaction is consistent with

DPM’s approach to shareholder returns, portfolio enhancements and leverages its

complementary capabilities and significant balance sheet strength.

3

DPM believes that it would be a well-suited operator of the Vareš Silver Operation (“ Vareš”)

given its financial strength and extensive experience and track record in the Balkans, where it

currently operates an underground mine and an open pit mine. DPM has fostered strong

partnerships with local governments and communities in the Balkan region and has a

demonstrated history of working to create sustainable benefits for its stakeholders and local

communities.

Vareš is a new underground precious metals rich mining operation, with a low-cost profile, long

mine life and attractive exploration potential. Furthermore, DPM’s proven exploration team is

excited about the additional upside potential from further exploration activities at the extensive

Vareš land package and, notably, the highly prospective Rupice Mine.

Consistent with DPM’s financial priorities of generating attractive returns for shareholders, DPM

expects the Transaction to be accretive, on a cash flow per share basis, in the first year post-

Completion, delivering attractive returns for existing DPM and Adriatic shareholders, with

additional upside from achieving and maintaining commercial production levels at Vareš,

leveraging corporate infrastructure optimisation and supply efficiencies.

From DPM’s perspective, the predominantly equity-based nature of the Transaction

consideration allows DPM to enhance its balance sheet strength which, when combined with

Adriatic, is expected to increase its ability to fund growth and continue to return cash to

shareholders through its current capital allocation and dividends policy.

The Transaction is expected to offer the following additional benefits:

 Improved Financial Strength. DPM anticipates that the Transaction will result in value

creation from corporate and other operational synergies and enhanced financial

flexibility to support the Combined Group’s growth initiatives. Specifically, DPM’s strong

balance sheet and cash flow is expected to fund remaining ramp-up requirements at

Vareš, construction capex for an additional operating mine and accelerate exploration

across its expanded portfolio, thereby resulting in meaningful value creation for the

Combined Group and avoiding dilution associated with large third-party financings.

 Optimised Capital Allocation and Investment. The Combined Group is expected to have

a strong balance sheet, with significant free cash flow generation and exposure to

mineral projects with strong economics across Bulgaria, Serbia, Ecuador and Bosnia

and Herzegovina, which DPM believes will enable the Combined Group to optimise

capital allocation, enhance its market valuation and investment across its portfolio of

mining assets. DPM also believes that the strength of the Combined Group (expected

to be evidenced by significant management expertise, free cash flow, a strong balance

sheet and borrowing base potential) will provide an excellent platform for future

investment and consolidation within the regions in which the Combined Group will

operate.

 De-Risking Mine Development. The completion of the Transaction is expected to

enhance DPM’s ability to successfully develop a mine and launch operations at its Čoka

Rakita Project, effectively de-risking the Čoka Rakita Project. By integrating Adriatic’s

experienced mining personnel into the Combined Group’s operations, DPM is expected

to demonstrate its ability to navigate the complexities of mine development and

mitigate associated risks.

 Continued Participation by Adriatic Shareholders. Scheme Shareholders, through their

ownership of New DPM Shares, will also participate in the mineral projects of DPM

along with the potential valuation re-rating associated with a diversified operating

portfolio, larger market capitalisation and more liquid shares.

4

 Strong and Proven Management Team. The Combined Group will benefit from the skill

and expertise of DPM’s current management team, who possess extensive experience

in mine development, operations, finance, exploration and rightsholder and stakeholder

engagement, all of which would accelerate the successful development of Adriatic’s

mineral projects.

 Enhanced Capital Markets Profile. The Transaction is expected to result in increased

scale and liquidity with enhanced market relevance and financial flexibility and a lower

cost of capital, with wider investor appeal and analyst coverage due to an even larger

market capitalisation, which could provide an opportunity for a re-rating of the DPM

Shares following completion of the Transaction.

Comments on the Transaction

Commenting on this Announcement, David Rae, the CEO of DPM, said:

“Adding Adriatic’s Vareš operation to our strong asset portfolio creates a premier mining

business with a peer-leading growth profile, high-quality development and exploration pipeline

and a robust platform to deliver above-average returns.

The Vareš is a logical fit with our portfolio, and adds near-term production growth and mine

life, a highly prospective land package, and cash flow diversification. We are well-positioned to

leverage our expertise in underground mining and our strong financial position to further

optimize the operation and realize Vareš full value potential, based on our analysis.”

Commenting on this Announcement, Laura Tyler, the CEO of Adriatic, said:

“The Vareš Silver Operation remains on track to become a low cost precious metal producer,

underpinned by a long mine life, a high-grade deposit and strong exploration potential. What

makes Vareš so exciting is that it is at beginning of its journey, with significant growth ahead.

This transaction brings together complementary strengths to create a dynamic and diversified

mining company with meaningful scale. The combined group will be well placed to pursue

additional value-additive opportunities. We see clear synergies between the asset portfolios of

DPM and Adriatic, supported by DPM’s strong financial capacity and proven operational

expertise. Together these strengths are expected to unlock further value for shareholders of

both companies, in both the near and longer term. Importantly, the creation of a diversified

mining company in the Balkan region will bring benefits not only to our employees and

shareholders, but also to local communities and broader regional stakeholders. This

Transaction presents a compelling opportunity to be part of a transformative and long-term

success story – one we fully endorse and recommend to all our stakeholders.”

Recommendation of the Adriatic Directors and Adriatic Directors’ Irrevocable

Undertakings

The Adriatic Directors, who have been so advised by RBC Capital Markets as to the financial

terms of the Transaction, consider the terms of the Transaction to be fair and reasonable. RBC

Capital Markets is providing independent financial advice to the Adriatic Directors for the

purposes of Rule 3 of the Takeover Code. In providing its advice, RBC Capital Markets has

taken into account the commercial assessments of the Adriatic Directors.

The Adriatic Directors intend unanimously to recommend that Scheme Shareholders vote (and

that Adriatic CDI Holders direct CDN to vote) in favour of the Scheme at the Court Meeting and

Adriatic Shareholders vote in favour of the Adriatic Resolutions to be proposed at the Adriatic

General Meeting (or in the event that the Transaction is implemented by way of a Takeover

Offer, to accept or procure acceptance of such Takeover Offer), as certain Adriatic Directors

who are interested in Adriatic Shares have irrevocably undertaken to do in respect of their own

beneficial holdings of, in aggregate, 1,572,383 Adriatic Shares (including in respect of Adriatic

5

Shares, the underlying Adriatic CDIs), representing, in aggregate, approximately 0.46 per cent.

of Adriatic’s issued share capital as at the close of business on the Last Practicable Date.

Adriatic Shareholder Irrevocable Undertakings

In addition, DPM has received irrevocable undertakings from the Supporting non-director

Shareholders to vote in favour of the Scheme and the Adriatic Resolutions in respect of a total

of 126,968,662 Adriatic Shares (including the underlying Adriatic CDIs) representing, in

aggregate, 36.77 per cent. of Adriatic’s total issued share capital as at the Last Practicable

Date.

Recommendation of the DPM Directors and DPM Directors’ and Executive Officers'

Voting Support Agreements

The issuance of the New DPM Shares pursuant to the Transaction requires the DPM Shareholder

Resolution to be approved by a simple majority of the votes cast by DPM Shareholders,

represented in person or by proxy, at the DPM Special Meeting.

The DPM Board has been advised by BMO as to the financial terms of the Transaction and

considers the Transaction to be in the best interest of DPM and fair to DPM, from a financial

point of view. The DPM Board intends to recommend that DPM Shareholders vote in favour of

the DPM Shareholder Resolution at the DPM Special Meeting. DPM Directors and Executive

Officers have irrevocably undertaken to vote in favour of the DPM Shareholder Resolution at

the DPM Special Meeting in respect of their own beneficial holdings of, in aggregate, 313,016

DPM Shares, representing, in aggregate, approximately 0.19 per cent. of DPM’s issued share

capital as at the close of business on the Last Practicable Date.

Transaction Structure and Timing

It is intended that the Transaction will be effected by means of a Court-sanctioned scheme of
