ALT Resources PLC

("ALTR" or the "Company")

Transaction Update and Fundraising

ALT Resources PLC, a company formed to pursue value-accretive opportunities in the mining, precious metals, and critical minerals sectors, is pleased to announce meaningful progress has been made to advance the proposed transactions with Tartana Minerals Ltd ("Proposed Transaction") since its prior announcement on 18 November 2025. ALTR is working with its professional advisers to complete the necessary due diligence on the Proposed Transaction and will provide a further update to shareholders in due course.

The Proposed Transaction will, if completed, constitute a Reverse Takeover under the FCA's Listing Rules since it will, amongst other things, result in a fundamental change in the business of the Company.

As previously announced, ALTR is in discussions with prospective investors to raise the necessary capital (the "Proposed Fundraising") to consummate the Proposed Transaction and facilitate the Company's proposed admission to trading on AIM ("Admission"). In connection with the Proposed Fundraising, the Company is pleased to announce that it has received commitments for £208,750 in advance of its planned Admission.

These commitments comprise:

1)   committed subscriptions of £100,000 to support Admission; and

2)   the issue of £108,750 unsecured convertible loan notes ("CLNs") to certain investors ("CLN holders"). The CLNs shall be convertible into shares in the capital of the Company, calculated by dividing the nominal value of the CLNs by the price per share of the Company placed with new investors as part of the Admission process. If Admission has not occurred by 4 February 2027, the CLNs will need to be redeemed at their nominal value.
