Extension of Redemption Period

Further to its announcement on 28 June 2024 (the "Acquisition Extension Announcement"), ACG announces today that the deadline by which Class A Ordinary Shareholders wishing to redeem all or a portion of their depositary interests in Class A Ordinary Shares are required to submit their redemption election electronically through the UK's Certificateless Registry for Electronic Share Transfer has been extended from 30 July 2024 until at least 1:00 pm London time on 13 August 2024 (such extension, the "Deadline Extension").

The Deadline Extension has been implemented to allow existing Class A Ordinary Shareholders of the opportunity to consider ACG's announcement on 18 July 2024 that it has signed an agreement for the acquisition of 100% of the shares in Polimetal Madencilik Sanayi ve Ticaret A.Ş. and associated sulphide expansion project financing (the "Acquisition") in connection with any exercise of their redemption rights. Further details relating to redemption, including the updated redemption price, will follow in a prospectus containing details of the Acquisition and a notice of a general meeting of ACG's Public Shareholders for the purpose of considering the Acquisition, both of which ACG expects to publish in due course.

Notwithstanding the Deadline Extension, the mechanics through which Class A Ordinary Shareholders may exercise their redemption rights remain as set out in the Acquisition Extension Announcement. The new redemption payment date will be announced in due course.

Unless otherwise defined, capitalised terms used in this announcement have the meaning set forth in the Memorandum and Articles of Association of the Company.
