2020 Sustainability Report Highlights

OUR APPROACH TO

RESPONSIBLE MINING

Sustainability is fundamental to the way we do business. As a global leader in responsible mining, it shapes our purpose, vision and values, and guides our individual and collective actions every day.

Our culture reflects our commitment to responsible mining, managing our impacts and, more broadly, contributing to the communities in which we work and live.

We approach sustainability performance as an opportunity to build a positive legacy and deliver value throughout and beyond the life of our mines. These societal outcomes are inextricably linked to the way we manage our operations and invest in sustainable, industry-leading practices at every level of OceanaGold.

As an employer and custodian of mine assets, we place significant value on safety, sustainability, integrity and diversity. Each year we strengthen our performance by better understanding our impacts and consistently improving and executing our sustainability policies and practices across our global operations.

Earning the right to operate long into the future means always building on our performance and working closely with communities, governments and global organisations. To support ongoing improvement, we play an active role in international, national and regional industry organisations, multi-stakeholder groups and events that allow us to share our experience and help us better understand and embed leading practice.

PERFORMANCE HIGHLIGHTS

November 2020 marked 30 years since we poured our first gold bar at the Macraes Operation in New Zealand. Since then, we have been contributing to excellence in our industry by delivering innovative solutions, sustainable environmental and social outcomes and strong returns.

While 2020 was a year like no other, we remained committed to delivering our responsible mining commitments. We:

• Made strides towards full compliance with the World Gold Council's Responsible Gold Mining Principles (RGMPs), receiving independent external assurance of our progress towards RGMP compliance by September 2022.
• Led our peer group and took climate action, releasing an updated Statement of Position on Climate Change, Energy Use and Greenhouse Gas and setting the goal to achieve net zero GHG emissions by 2050.
• Invested more than US$4 million in social programs, donations, in-kind support and community infrastructure; more than US$99 million in local procurement; and US$135.8 million in employee wages and benefits.
• Bolstered our approach to Human Rights and Modern Slavery, and released our first Modern Slavery
  Statement in 2021.
• Updated our corporate strategy to support company-wide performance, organic growth and investment goals that are underpinned by our purpose, vision and values.
• Shifted focus from expansion to targeted resource development and exploration opportunities in existing gold deposits within our current mining footprint.
• Laid down our foundations for a constructive culture and reviewed our purpose, vision and values, known as The OceanaGold Way, to drive leadership impact.

2020 PERFORMANCE IMPACTS

There were two major impacts to our operational performance and results in 2020 that were outside our sphere of control:

1. The global COVID-19 pandemic and associated lockdowns in the countries in which we operate
2. The ongoing suspension of mining and processing operations at our Didipio Mine in the Philippines, pending the mine's FTAA (Financial or Technical Assistance Agreement) renewal.

The full extent of these two major operational impacts is explained in detail our 2020 Sustainability Report.
