Environmental
Stewardship
Our Approach
Environmental stewardship is a foundational element of Evolution’s Sustainability Strategy and essential to maintaining our regulatory and social licence to operate. We operate beyond legal compliance in line with the precautionary principle and Evolution’s Integrated Risk Management Framework. In accordance with the Sustainability and Strategic Planning Policy and associated Standards, we incorporate environmental management, including climate change, into all areas of the business to manage risks, impacts and opportunities throughout the mine life cycle, from due diligence through to closure and economic/environmental transformation.Â
We strive for safe and sustainable consumption and production to support long-term environmental outcomes. Our strategic approach comprises proactive and consistent risk-based environmental and climate risk management, underpinned by continuous feedback and improvement.



We understand the critical importance of environmental stewardship and the effective mitigation of risks to manage biodiversity, cultural heritage and other environmental impacts across our footprint.
MATT O'NEILL
CHIEF OPERATING OFFICER


During FY24, we continued to:
- Assure our environmental stewardship, with audits against our Standards and reviews against legislative obligations.
- Build internal capability and competence, in alignment with global standards and frameworks, including planning for closure at Mt Rawdon, ISO 14001 at Cowal and Northparkes and the ICMC at Cowal and Red Lake.
- Enhance planning, resilience, and mitigation against climate-related risks of extreme weather events, and water security by minimising raw water demand in processes and maximising reuse or recycling.
- Monitor surface water, groundwater, land and nature, noise, vibration and air emissions to assess effectiveness of mitigants and protect and enhance the wellbeing of the environment and community.
- Assess and implement energy efficiency and GHG emissions monitoring, forecasting and reduction initiatives, partnerships and projects.
- Progress nature-based opportunities in biodiversity stewardship and passive water treatment.
- Follow strict protocols for storage, handling, labelling and disposal of hazardous materials, including wastes to protect the workforce, communities and environment.
- Consult with stakeholders, local communities, First Nations partners and regulatory authorities on mine planning, operations and post-mine land use.
Environmental Compliance
Management Approach
Effective management of mining-related activities sits at the core of our approach to environmental compliance, as we focus on protecting cultural and environmental values, including the rights and interests of local communities. Our operations are subject to environmental regulation in the jurisdictions in which we operate through permitting, approvals and regulatory compliance requirements. Permit and licence provisions provide stringent requirements to support the health and safety of local communities and the environment.
All operations are required to maintain regular monitoring and reporting to demonstrate compliance with current legal and other obligations, supported by assurance activity.
A uniform internal reporting system is implemented across all operations. All environmental events, including potential non-conformance to any licence provisions, are assessed according to their actual or potential environmental and/or regulatory consequence. Levels of environmental incidents are tracked based on factors such as spill volume, incident location (onsite or offsite), potential or actual environmental impacts and legal obligation, on a scale from Very Minor to Extreme in alignment with the Evolution Risk Assessment Matrix.
Performance
In FY24, all operations retained a strong focus on environmental performance with no material environmental incidents reported. Two Moderate category events were recorded with one event being two fines (>US$10,000) issued and paid in relation to administrative non-compliances at Cowal associated with delayed submission of spatial files in accordance with the site’s Environment Protection and Biodiversity Conservation Act 1999 approval. In another event, an environment protection order was issued to Mt Rawdon for a non-compliance in late 2022 related to the release of water associated with an unseasonal rainfall event. This matter was addressed through maintenance of instrumentation and closed out in FY24. Other Minor or Very Minor risk events occurring during FY24 were reported to the relevant government authority, where required, and remedial action taken, where appropriate.
In FY24, Mt Rawdon and Northparkes conducted triennial independent third-party (LOD3) audits of compliance with environmental permits, in accordance with regulatory requirements. Both sites achieved >95% compliance, with identified non-compliances either already addressed or plans implemented to address.
