Performance and Initiatives To strengthen wastewater monitoring and management, settling ponds have been installed at key locations. These ponds are designed to separate solid pollutants from mining wastewater, helping to ensure that discharge quality standards are met before release into public systems. Expanded Scope and Key Metrics Since 2023, we have continued to broaden the scope of our water discharge monitoring, improving the coverage and quality of our water-related data. In 2025, we made further progress by strengthening the tracking of water withdrawal and discharge across our mining operations, incorporating additional operational insights and environmental performance indicators. These enhancements support more consistent reporting and enable earlier identification of water-related risks. We will continue to build on these e!orts by advancing our monitoring practices and enhancing the transparency of our water-use reporting to meet regulatory requirements and support responsible resource management. Commitment to Compliance We manage and minimise significant water-related impacts by maintaining zero incident of non-compliance with discharge limits. All water-related activities are carried out in accordance with the requirements of the Regional Environmental Agency (Badan Lingkungan Hidup Daerah, BLHD), and periodic monitoring reports are submitted to the agency as part of our regulatory obligations. Continuous Improvement To reduce the impact of our activities on water resources, our e!orts focus on: • Strengthening the monitoring of water usage across all operations • Applying more stringent controls to manage and reduce overall water consumption WASTE GRI 3-3, 306-1 to 306-3, 306-5 Policies, Procedures, and Practices Our mining activities generate substantial volumes of liquid and solid waste, which, if not properly managed, could pose environmental risks. To mitigate these impacts, we align our waste management practices with international standards and comply with all relevant local regulations, including but not limited to: • Minister of Environment Regulation No. 14 of 2013 regarding the Symbols for Hazardous and Toxic Substances • Government Regulation No. 101 of 2014 regarding Management of Hazardous and Toxic Waste • Minister of Environment and Forestry Regulation No. 55 of 2015 regarding the Procedures for Testing the Characteristics of Hazardous Waste • Minister of Environment and Forestry Regulation No. 56 of 2015 regarding Procedures and Requirements for the Management of Hazardous Waste from Healthcare Facilities • Minister of Environment and Forestry Regulation No. 95 of 2018 regarding Licensing for the Management of Hazardous Waste • Minister of Environment and Forestry Regulation No. 12 of 2020 regarding Storage of B3 Waste All waste, including hazardous (B3) and non-hazardous materials, is managed by authorised waste management contractors in full compliance with industry standards and environmental regulations. Management of hazardous waste is prioritised through the provision of appropriate personal protective equipment and structured training for relevant personnel. Material Safety Data Sheets are utilised to support the safe and e"cient storage and handling of waste generated as by-products of operational activities. Hazardous Waste We adopt a precautionary approach in the management of hazardous waste, guided by the SOP-015-HSE-2017 Hazardous Waste Management Standard Operating Procedures and applicable local regulations. All required documentation is maintained in accordance with regulatory requirements, including the Technical Details for Hazardous Waste (Rincian Teknis Limbah B3) for our SDJ, TRA, and TBR mines. 29
