ACG Acquisition Company Limited

("ACG" or the "Company")

Closing of Acquisition

ACG is pleased to confirm the closing of the acquisition of the Gediktepe Mine in Türkiye from Lidya Madencilik Sanayi ve Ticaret Anonim Şirketi (the "Seller"), a subsidiary of Istanbul-based conglomerate Çalık Holding (the "Acquisition").

Re-Admission of the Enlarged Ordinary Capital and Listed Warrants will now take place at 8.00 a.m. (London time) on 5 September 2024.

Capitalised terms not otherwise defined in this announcement have the meaning ascribed thereto in ACG's prior announcement on 30 August 2024.

Summary of Acquisition

·    The transaction establishes ACG as a high growth copper miner on the London Stock Exchange and marks the first step in the Company's vision to consolidate the sector through a series of roll-up acquisitions.

·    The Gediktepe Mine is an operating open pit mine located in the Balıkesir Province of Western Türkiye. Currently producing gold and silver from oxide ore, Gediktepe is expected to transition to primary copper and zinc production from 2026.

·    The completion of the Acquisition marks the beginning of ongoing strategic partnerships with both Lidya and its parent company Çalık Holding. Equity commitments from ACG's Co-Sponsors, Traxys, and global commodities group Glencore are a vote of confidence in ACG's vision for continued growth in the copper sector.

·    Development plans, which have secured all critical permits and licences, target annual steady-state copper equivalent production of 20-25 kt over an initial 11-year mine life starting in 2026.

·    In addition, the Company continues to work diligently on the next possible acquisition targets to rapidly deliver on its strategy of building a sizeable, low-cost copper producer through M&A led growth strategy.

·    ACG is to be renamed ACG Metals shortly after the Re-Admission to the London Stock Exchange.

Artem Volynets, Chairman and CEO of ACG, stated:

We are very pleased to announce the completion of the acquisition of the Gediktepe mine in Türkiye.

This acquisition positions ACG Metals as a premier copper producer on the London Stock Exchange and provides us with an excellent platform for the further consolidation of copper assets globally, as demand for the metal continues to rise.

We are also very happy to begin a new strategic partnership today with Lidya and Çalık Holding, who share our vision for the long-term development of the mining industry, and the pursuit of operational excellence at the Gediktepe site.
