ALT Resources PLC

("ALTR" or the "Company")

Transaction Update

Further to the announcement by the Company dated 28 May 2026 in relation to its proposed transaction with Tartana Minerals Ltd ("Tartana"), ALT Resources PLC (ALTR.L) notes the recent ASX announcements released by Tartana concerning:

-     an unsolicited, non-binding and indicative strategic investment proposal received by Tartana from a third party; and

-     the Notice of Extraordinary General Meeting for a meeting to be held at 11.30 a.m. AEST on Monday, 17 August 2026 (the "EGM"). The EGM is being convened by Tartana following a notice of intention to remove directors served on the company by an entity controlled by Tartana director Sonny Didugu. The EGM proposes a board spill, in which the election of all current directors of Tartana, including Mr Didugu will be put to a vote of shareholders.

ALTR notes that Tartana has stated that there is no certainty that the unsolicited proposal will result in a binding transaction or that it will ultimately constitute a superior proposal.

The Company remains engaged with Tartana and its advisers in relation to its proposed transaction with Tartana and continues to monitor developments closely.

ALTR will provide further updates in due course and in accordance with its obligations as the proposed transaction progresses.
