Ogier in Jersey advises MAC Copper Limited on $1.03 billion acquisition

Ogier's Corporate and Dispute Resolution teams in Jersey have advised MAC Copper Limited on its US$1.03 billion acquisition by a company within the Harmony Gold Group, implemented by a Jersey scheme of arrangement.

MAC Copper Limited (MAC) was established by Ogier in 2022 and acquired the Cobar CSA mine, one of the highest grade copper mines in Australia. It is listed on New York Stock Exchange (NYSE) and the Australian Securities Exchange (ASX). MAC shareholders approved the transaction on 29 August 2025, with the Royal Court of Jersey subsequently sanctioning the scheme on 9 October 2025.

Following implementation of the scheme later this month, Harmony will acquire the entire issued share capital of MAC. The acquisition was implemented by way of a Jersey scheme of arrangement under Article 125 of the Companies Law (Jersey) 1991.

Ogier's advice was a collaboration between Jersey's Corporate and Dispute Resolution teams, led by Corporate partner Raulin Amy and Dispute Resolution partner James Angus, assisted by managing associate Alex Fisher, senior associates Ralph Spencer-Tucker and Mark Watson and associates William Greenall and Alex Vibert. The Ogier team acted alongside Australian counsel from Gilbert & Tobin and US counsel Skadden.

Raulin Amy said: "It was a pleasure to have supported the team at MAC on this transaction, which marks the culmination of several years of hard work. We look forward to seeing MAC's continued success under Harmony's ownership and to working with the team again in the future."

MAC's acquisition is another example of Ogier's ongoing strength in the natural resources sector. Previously, Ogier advised Arcadium Lithium on its scheme of arrangement by which it was purchased by Rio Tinto in March of this year and prior to that acted for Centamin plc on its acquisition via scheme of arrangement by Anglo Gold Ashanti in November 2024.
