Recommended A$0.08 Per Share Cash Offer

TORONTO, May 19, 2025 - Xanadu Mines Ltd. (ASX:XAM, TSX:XAM) (Xanadu or the Company) and Bastion Mining Pte Ltd (Bastion) are pleased to announce that they have entered into a Bid Implementation Agreement on 19 May 2025 under which Bastion will make an off-market takeover offer to acquire all the fully paid, ordinary shares issued in Xanadu (Xanadu Shares) which Bastion does not already own, at a price of A$0.08 cash per Xanadu Share (Offer).

A copy of the Bid Implementation Agreement is attached as Annexure A to this announcement.

The Offer is made by Bastion, which represents a consortium of Boroo Pte Ltd (Boroo) and Xanadu Director Ganbayar Lkhagvasuren (together, the Bid Sponsors). Boroo is a private Singapore-incorporated entity which invests in major gold projects internationally. Boroo key assets include Lagunas Norte, a producing gold mine in Peru and a portfolio of development-stage projects in South America. Boroo has guaranteed Bastion's obligations as bidder under the Bid Implementation Agreement.

Xanadu's Takeover Board Committee¹, together with Xanadu's legal and financial advisers, have carefully considered the Offer. The Takeover Board Committee Directors unanimously recommend that Xanadu shareholders ACCEPT the Offer in the absence of a superior proposal and subject to the Independent Expert concluding (and continuing to conclude) that the Offer is fair and reasonable.

Xanadu Executive Chairman and Managing Director, Mr Colin Moorhead, said:

"The proposed acquisition of Xanadu by Bastion is aligned with the Company's strategy of generating returns for shareholders and also providing a liquidity event. Bastion's Offer provides Xanadu shareholders with an attractive premium, which recognizes the Company's inherent value and considerable achievements in progressing the Kharmagtai Copper-Gold Project. The Takeover Board Committee Directors consider the Offer to be in the best interest of shareholders and unanimously recommend that shareholders accept the Offer in the absence of a superior proposal and subject to the Independent Expert concluding (and continuing to conclude) that the Offer is fair and reasonable."

Mr. Ganbayar Lkhagvasuren, on behalf of Bastion, said:

"Together with my partners at Boroo, I am pleased to be making this supported Offer to Xanadu shareholders. The Bastion Offer provides Xanadu shareholders with the certainty of cash at a significant premium to Xanadu's share price, against a market backdrop of considerable uncertainty. Bastion is ideally positioned to advance Kharmagtai to the next stage of development with the benefit of Boroo's experience in acquiring, financing and developing mining operations in Mongolia."

Bid Implementation Agreement

Under a Bid Implementation Agreement dated 19 May 2025 (BIA), Xanadu and Bastion have given undertakings to each other to facilitate the Offer. The Offer is subject to a limited number of conditions as noted below.

• Bastion obtaining a relevant interest in Xanadu of at least 50.1%.
• Until the end of the Offer period, Xanadu must not exercise either of the put options granted under the terms of the Joint Venture Shareholders' Agreement³ which, if exercised, would require Jinping (Singapore) Mining Pte. Ltd (Jinping) to acquire either 25% or 50% of Xanadu's shareholding in Khuiten Metals Pte Ltd (Khuiten Metals).
• No prescribed occurrence in relation to Xanadu.
• No material adverse change in relation to Xanadu.
• No government or regulatory action in consequence of, or in connection with, the Offer which adversely impacts the Offer (subject to certain carve outs).
• None of the warranties given by Xanadu become incorrect or untrue during the Offer period.

Bastion has committed to declare the Offer unconditional upon achieving a relevant interest in the Company of 50.1%.

The BIA also contains terms usual for a transaction of this nature, including customary exclusivity arrangements such as 'no shop', 'no talk' and 'no due diligence' restrictions as well as a right for Bastion to match any competing proposal. A break fee or a reverse break fee may also be payable in certain circumstances.

Details of the key terms and conditions of the Offer are set out in the attached BIA. Full details of the Offer will be set out in Xanadu's Target's Statement (which will enclose a copy of the Independent Expert's Report).

Equity Funding Arrangements

To assist Xanadu in meeting its corporate and joint venture funding obligations during the Offer period, Bastion and Xanadu have entered into a share subscription agreement (Subscription Agreement) under which Bastion has agreed to subscribe for 286,829,633 Xanadu Shares at an issue price of A$0.06 per share (Subscription Shares).

The issue of the Subscription Shares is expected to occur on 26 May 2025 (Settlement Date), unless the Subscription Agreement is terminated prior to completion. In particular, if a competing proposal is received prior to the Settlement Date and Xanadu either (1) does not confirm that the competing proposal is not a superior proposal in accordance with the BIA, or (2) fails to recommend that shareholders reject the competing proposal, Bastion may elect to terminate the Subscription Agreement in which case the subscription will not occur.

If completion of the Subscription Agreement occurs as intended:

• the Subscription Shares will be issued under Xanadu's available placement capacity pursuant to ASX Listing Rule 7.1;
• Xanadu will receive a cash injection of A$17.2 million; and
• Immediately following settlement, Bastion will hold a relevant interest in 13.04% of Xanadu Shares.
  

Withdrawal of the 25% Put Option Resolution

Currently, an extraordinary general meeting of members is scheduled to be held on 4 June 2025 at which members will be asked to consider and approve a resolution authorising Xanadu to exercise the put option which requires Jinping to acquire 25% of Xanadu's shareholding in Khuiten Metals (Put Option Resolution).

However, in light of the Offer and the funding to be received by Xanadu upon issue of the Subscription Shares, the Takeover Board Committee has committed to withdraw the Put Option Resolution following successful completion of the equity funding arrangements under the Subscription Agreement.

Indicative Timetable

Further details regarding the Offer and Takeover Board Committee's recommendation will be outlined in Bastion's Bidder's Statement and Xanadu's Target's Statement, which are expected to be despatched to Xanadu Shareholders on or about 28 May 2025, following completion of the equity funding arrangement under the Subscription Agreement.

Once the Bidder's Statement has been despatched, the Offer will open for acceptance. The Offer will initially remain open for a minimum period of one month.

The Bidder's Statement and the Target's Statement will set out important information, including the Independent Expert's Report (with detail supporting the conclusion of the Independent Expert), how to accept the Offer, and the key reasons why Xanadu shareholders should accept the Offer.

An indicative timetable for the Offer is set out below.
