Upholding the highest standards of governance is central to how we deliver enduring value and sustainable practices across our business.

At OceanaGold, every pillar of our organisation is guided by our Responsible Mining Framework.

From exploration through to operations and closure, we identify and manage our environmental and social impacts across the entire lifecycle of our assets. In doing so, we commit ourselves to the highest standards of governance, acting ethically and with integrity in every stakeholder interaction.

Our decision-making process considers all aspects of the business, including economic impacts and opportunities, health and safety, environment, people, host and adjacent communities, our investors, business partners, and society more broadly.

Strengthening our corporate sustainability is a continual focus, led by an Integrated Management System that sets out the policies, standards and business performance that support our vision and values. It’s this holistic approach that enables us to grow and optimise our operations with strong management systems and practices at each level of the company.
