ALT Resources PLC

("ALTR" or the "Company")

Transaction Update and Intention to delist from the Main Market

ALT Resources PLC, a company formed to capture value-accretive opportunities in the natural resources industry, announces an update in relation to its proposed transaction with Tartana Minerals Ltd ("Tartana") .

The Company is in the process of finalising the proposed transaction with Tartana ("Proposed Transaction"), and is working with its professional advisers to complete documentation relating to the equity fundraise which is being undertaken in conjunction with the Proposed Transaction, along with the Company's AIM Admission Document in relation to its proposed admission of the Company's ordinary shares of £0.002 each ("Shares") to trading on AIM ("Admission").

In conjunction with the Proposed Transaction, the Company announces its intention to cancel the listing of the Company's ordinary shares on the Equity Shares (Shell) category of the Official List of the Financial Conduct Authority ("FCA") and to cancel the trading of its ordinary shares on the Main Market of the London Stock Exchange (together, the "Cancellation").

As a company listed on the Equity Shares (Shell) category, the Company is not required to obtain the approval of its shareholders for the Cancellation but is required under UK Listing Rule 21.2.17 to give at least 20 business days' notice of the intended cancellation.

Accordingly, the Company has requested the FCA to cancel the listing of its Shares on the Official List and the London Stock Exchange to cancel the admission to trading of the Shares on its Main Market for listed securities.

It is expected that Cancellation and Admission will occur simultaneously.

It is anticipated that the Cancellation will become effective in not less than 20 business days.  Full details regarding the specific timing of the Cancellation, the Company's proposed Admission to the AIM Market, and the completion of the Proposed Transaction, will be provided in due course.

The timeline above remains indicative and is subject to change. If any of the above times and/or dates change materially, the revised times and/or dates will be notified to shareholders by way of a further announcement.
