We engage in ethical business practices grounded in transparency, accountability, and integrity to enhance trust with our stakeholders throughout the mine life and beyond. Our Code of Conduct aligns with the UN Convention against Corruption and supports legal protections for whistleblowers under national and international frameworks.

We recognize that while our activities can positively impact the lives, livelihoods, and rights of individuals and communities, there is also the potential to cause, contribute to, or be directly linked to negative human rights impacts. We are committed to preventing and mitigating human rights impacts associated with our activities, while contributing to the broader societal respect of human rights.

To meet this commitment, we conduct ongoing human rights due diligence across our operations. This includes identifying and assessing potential risks, engaging directly with affected stakeholders, and integrating findings into our risk management systems. We monitor the effectiveness of our actions and address impacts through remediation processes where required. This approach helps us anticipate issues early, respond transparently, and continuously strengthen our performance.
