Nature

MMG is committed to responsible land stewardship and the protection of nature, which encompasses biodiversity, water, air, land, water and cultural heritage across the full mining life cycle.  Our approach is guided by our Nature Strategy, launched in 2025, which embeds nature into decision-making, planning, and operations across all sites. 

Nature Strategy 

At MMG, we recognise that nature is not just a backdrop to our operations—it’s a vital part of our business, our communities, and our future. Our Nature Strategy, launched in June 2025, reflects a bold commitment to halt and reverse biodiversity loss, build climate resilience, and embed nature into every aspect of how we work.  

Nature underpins the health of our ecosystems, the stability of our operations, and the wellbeing of our host communities. As global expectations rise and frameworks like the Taskforce on Nature-related Financial Disclosures (TNFD) emerge, MMG is taking proactive steps to address nature-related risks and opportunities. 

Our Strategic Pillars 

The strategy is built around four interconnected pillars: 

1. Governance and Transparency 

  • Establish a Nature Governance Framework and decision-making policies that integrate nature risks. 
  • Disclose material nature-related impacts, dependencies, risks, and opportunities. 
  • Set and report on performance targets aligned with global standards like ICMM and TNFD. 

2. Understanding and Valuing Nature 

  • Conduct LEAP assessments (Locate, Evaluate, Assess, Prepare) at each site. 
  • Develop a Nature Work Quality Requirement (WQR) and update SSHE standards. 
  • Improve baseline data and monitoring systems to track nature-related metrics. 

3. Addressing Nature Risks and Impacts 

  • Apply the mitigation hierarchy: avoid, minimise, restore, and offset. 
  • Adjust Land and Biodiversity Management Plans to reflect site-specific risks. 
  • Implement initiatives to achieve no net loss of biodiversity by mine closure. 

4. Fostering Collaboration and Engagement 

  • Partner with Indigenous communities, governments, and peers. 
  • Share biodiversity data and participate in landscape-scale restoration. 
  • Explore sustainable finance and systems transformation opportunities. 

 Implementation is driven locally, with teams conducting LEAP assessments to identify dependencies and impacts. We’re working closely with Indigenous and local communities, applying innovative restoration practices, and integrating nature into land stewardship and sustainability planning. 

Land Access and Protected Areas 

MMG does not explore or mine within the boundaries of UNESCO World Heritage Listed properties. Where activities occur adjacent to protected areas, we ensure compatibility with the Outstanding Universal Values and comply with all relevant national and international regulations. Our land access protocols are guided by our SSHE Performance Standard and include stakeholder engagement, environmental assessments, and cultural heritage screening. 

We respect legally designated protected areas and ensure that any operational changes are compatible with land use designations. In line with our Nature Strategy, we are enhancing our site-level assessments to better identify nature-related risks and dependencies.  

Biodiversity Management and Mitigation 

MMG applies the mitigation hierarchy—avoid, minimise, restore, offset—throughout the project life cycle In 2024, 28 nature-related performance metrics were tracked under our Nature Strategy. 

Where impacts to biodiversity are unavoidable, we implement species relocation, habitat restoration, and biodiversity offset programs developed in collaboration with ecological experts and local communities. Our biodiversity management system incorporates tailored assessments at each site to evaluate ecological sensitivity and ecosystem dependencies. 

We are currently assessing the feasibility of adopting a no net loss or net gain biodiversity commitment, aligned with the TNFD and ICMM Nature Position Statement. 

Governance and Disclosure 

MMG has established a governance framework for nature that includes Board oversight through the GRNS Committee. We disclose material nature-related impacts, dependencies, risks, and opportunities in priority locations and across our value chain.  

We are undertaking LEAP assessments to quantify nature-related risks and opportunities unique to each site, and have amended SSHE documentation to reflect our updated nature assessment protocols. 

Progressive Rehabilitation and Final Land Use 

MMG undertakes progressive rehabilitation where feasible, focusing on operational zones currently in use or planned for future use. Rehabilitation objectives are aligned with proposed final land use and informed by stakeholder input. 

In 2024: 

  • Rehabilitation success monitoring was conducted at Las Bambas, Kinsevere, and Dugald River 
  • Drainage, erosion, and dust control measures were implemented across disturbed areas 
  • Revegetation programs used native species and traditional land management practices 

While MMG does not set annual rehabilitation targets, performance is tracked through site-level KPIs and disclosed in our Sustainability Report. 

Our goal is to achieve no net loss of biodiversity by closure, benchmarked against a 2020 baseline that includes site-specific ecological assessments and biodiversity inventories. This commitment ensures that any residual impacts from our operations are fully mitigated through restoration, offsetting, and long-term stewardship programs. We are integrating this goal into closure planning, rehabilitation design, and stakeholder engagement processes, and are exploring pathways to transition from no net loss to net gain in priority ecosystems, in alignment with the TNFD LEAP framework and ICMM’s Nature Position Statement.
