 events. Closure and repurposing We are committed to being responsible operators throughout the entire life of our assets, delivering value at every stage – from discovery to closure. Today, we plan for the end right from the beginning, incorporating closure in each stage of the asset lifecycle in the way we design, build and operate. We work with communities, governments and other stakeholders to complete closure activities and repurpose and renew sites for their next use. At the end of 2024, closure provisions on our balance sheet totalled $15.7 billion (2023: $17.2 billion ). 2024 progress In 2024, we continued to mature our closure practices and develop our expertise through our approach. Argyle diamond mine We are rehabilitating the Argyle diamond mine on the traditional lands of the Miriwoong and Gija People in Western Australia. We have made significant progress on reprofiling the former processing plant area and waste rock dumps, as well as capping the tailings storage facility. We have reached over 60% overall project completion, and plans are underway to start removing the Argyle mine accommodation facilities, airport and utilities infrastructure in 2025. We are continuing to review our contracting strategy to increase work awarded to Traditional Owner businesses and increased our spend to A$44.9 million in 2024 (2023: A$37 million).

Gove refinery and residue disposal areas In 2024, we reached the halfway mark for the demolition works at the Gove alumina refinery in the Northern Territory, which is Australia’s largest demolition project. We have removed the refinery’s liquor purification units and other structures, processing around 63,000 tonnes of scrap steel for recycling. The majority of the rehabilitation of the former tailings dam, Pond 5, is complete, with the opening of 3 spillways to allow appropriate drainage from the newly capped surface. We continue to work closely with Gumatj and Rirratjingu Traditional Owners, and the Northern Territory Government, to plan for a future beyond mining. In 2024, we spent A$85.5 million with Traditional Owner businesses (2023: A$94 million). Ranger Rehabilitation Project In April 2024, we entered into a Management Services Agreement (MSA) with Energy Resources of Australia (ERA) to manage the Ranger Rehabilitation Project with oversight from the ERA board.
