Bannerman Energy says it will review and update its Mine Closure Plan in 2026 to ensure that evolving design details, environmental data and operational considerations are fully incorporated into closure planning ahead of future mine development.
According to the company’s 2025 Sustainability Scorecard, Bannerman will also review and rank waste rock types to assess their suitability for covering spent heap-leach material (ripios) and other materials at closure, as part of efforts to align with Good International Industry Practice across the project life cycle.
“Review and update the Mine Closure Plan and related costs, taking into account updates to the detailed design,” Bannerman said in the report.
Beyond closure planning, the company outlined several environmental and operational priorities for 2026.
These include strengthening waste management through the formalisation of a comprehensive waste management plan, developed in partnership with waste removal and recycling service providers.
Bannerman said it will also review environmental performance in municipalities that receive construction waste from the Etango project to ensure disposal practices are safe and compliant.
Safety remains a core pillar of the company’s sustainability framework. Bannerman said that after recording 16 consecutive years without a lost-time injury (LTI) in 2025, it is targeting 17 years LTI-free.
The company also plans to increase awareness among mutual aid and public response groups of Etango’s emergency management protocols for transport and workplace incidents.
Workforce development has been identified as another priority. Bannerman said it will expand and refine its capability framework in 2026 to address the increased complexity associated with the transition from project development to operational readiness.
The company also plans to formalise and embed its Employee Value Proposition, with a focus on employee wellbeing, diversity, equity, communication and feedback.
“Implement software to plan, do, check and act, record and report across Bannerman’s sustainability disciplines. Train Bannerman responders to register calls to Bannerman’s contact line in the sustainability software and report on the nature of contact, including grievances,” the company said in the scorecard.
Governance and transparency targets include advancing ethics and compliance training and securing board approval and publication of Bannerman’s new Supply Chain Code of Conduct, the company said.
