Appointment of Joint Lead Managers for Australian Securities Exchange Listing

GRAND CAYMAN, Cayman Islands–(BUSINESS WIRE)–Metals Acquisition Corp. (NYSE: MTAL.U):

• Metals Acquisition Corp. (NYSE: MTAL.U) (�MAC”) is pleased to announce that it has mandated Barrenjoey Markets Pty Ltd (“Barrenjoey”) and Canaccord Genuity (Australia) Limited) (“Canaccord”) as Joint Lead Managers for a proposed dual listing of MAC on the Australian Securities Exchange (“ASX”) following the closing of its acquisition of the CSA Mine from Glencore

Commentary

Mick McMullen, MAC CEO, said: “Given the location of the CSA Mine in western NSW and the lack of ASX listed companies with domestic copper exposure, we think that listing MAC on the ASX is logical and provides MAC with access to an additional source of capital in the future.

“Barrenjoey and Canaccord are two of the leading equity capital markets franchises in Australia, successfully raising capital for clients in the metals and mining space including companies focused on commodities essential to the energy transition.

“We believe that recent merger and acquisition activity in the copper sector has highlighted the appetite for domestic copper producers. The few listed Australian copper names are trading at stronger multiples than North American peers, reflective of the significant premium attributed to operating in a Tier 1 jurisdiction and also, the significant pool of mining focused capital in Australia.

“A listing on the ASX would occur post-closing of the CSA Mine acquisition, and the timing and quantum of any associated equity raise would be market dependent. However, we cannot provide any certainty as to when or if an ASX listing or associated equity raise would occur.”
