Our approach to Sustainability

Hillgrove Resources is dedicated to creating shared value for all our stakeholders while achieving sustainable practices that minimise environmental impact, reduce greenhouse gas emissions, support social well-being, and promote economic viability.

We report annually on the sustainability topics that are most material to our business and stakeholders including our management approach related to each topic. Read our latest interactive Sustainability Report here.

Our strategic values of Safety, Integrity and Delivery support the Company’s vision of being a mid-tier, multi-asset Australian copper producer unlocking value for a sustainable future.

We are dedicated to creating shared value for all our stakeholders while achieving sustainable practices that minimise environmental impact, reduce greenhouse gas emissions, support social well-being, and promote economic viability.

Our vision and values are supported by our alignment with the ICMM Mining Principles which respond to evolving societal expectations of the mining and metals industry.

Our commitment to Sustainability includes:

Actively engaging with Local Communities to address their concerns and share benefits
Prioritising the Health and Safety of employees, contractors, and local communities
Maintaining Stewardship in Land Disturbance and rehabilitating disturbed areas for post-mining use
Implementing Water Management practices to protect local water sources from depletion or contamination
Responsibly managing Waste Material to minimise environmental harm
Conducting operations in a manner that preserves local Ecosystems and Biodiversity
Acknowledging and respecting Indigenous Rights and Cultural Heritage in our interactions
Upholding Transparency, Integrity, and Ethical Practices in all business dealings
Contributing to the Local Economy through employment, skills development, and procurement from local suppliers
Innovating for a more sustainable future

From 2026 onwards we will be expanding our reporting to reflect the operational status of our Kanmantoo mine. Building on our updated materiality assessment, key performance metrics will be identified and disclosed annually, including key data linked to the new mandatory climate reporting requirements for Australian companies.

Material Sustainability Topics

We have updated our materiality assessment to reflect the progression to operational status at Kanmantoo. Results from the assessment are summarised in the proposed materiality matrix below:

Detailed information can be found in Hillgrove’s Sustainability Report. The Sustainability Report maps out the actions and achievements delivered to date based on the 2024 material topics where they are relevant, including actions and achievements delivered during the year.

Our next Sustainability Report will report against the proposed material topics provided in this Report following validation of these topics during 2025, applying industry standards and metrics where possible.

Key 2024 highlights:

Achieved a 14% reduction in Total Recordable Injury Frequency (TRIF), though we recognise that more work is needed to ensure the safety of our workforce
Elimination of onsite diesel generation and the speed of decarbonisation of the South Australian grid also continues to accelerate our reduction in Scope 2 emissions
Progressed the Kanmantoo Grassy Woodland Revegetation Program - establishing an important multi-kilometre greenbelt which connects the existing mining rehabilitation works at Kanmantoo with regional vegetation initiatives - providing linkages for ground-based fauna and birdlife between disparate vegetation patches and restoring important ecological diversity to the region
Maintained an almost entirely residential workforce demonstrating our strong commitment to local employment
Supported our local communities through sponsorships, donations and traineeships
Published our Climate Change Position Statement
Completed a materiality assessment, supported by an external sustainability consultant, to identify new Sustainability topics material to our business

Looking ahead, our focus for 2025 includes:

Continuing to support the Kanmantoo Grassy Woodland Revegetation Program
Continuing to play an active role in the Kanmantoo Callington Community Consultative Committee (K4C) - $50,000 in funding is pledged to move the K4C Master Plan from conceptual to scoping stage
Completion of a Climate Change Risk Assessment of our operations
Further informing and validating of new material sustainability topics with external stakeholders to ensure alignment with emerging expectations and best practices
Improving our reporting alignment with global sustainability reporting frameworks, and preparing for upcoming mandatory climate change reporting
We are committed to implementing and upholding high standards in our sustainability practices to create enduring value for our shareholders and broader communities and to achieve our vision of becoming a mid-tier, multi-asset Australian copper producer, unlocking value for a sustainable future
