ABx3 appointed Onterris Australia to prepare and deliver the Sunrise Site-Specific Environmental Authority and Progressive Rehabilitation and Closure Plan, with the approvals process expected to finish in 2027. GII prioritised Sunrise and allowed its A$4.8 million option for 75% of ABx2 to expire unexercised on 11 August 2026, leaving ABx with 100% of Taralga and Penrose and the non-refundable A$300,000 option fee.
