The theme underscores the company's continued leadership in responsible mining and sustainable development.

Marna Cloete, president and chief executive officer of Ivanhoe Mines, commented:

"Two thousand twenty-five was a pivotal year for Ivanhoe Mines as we transitioned into a major, diversified metals producer. Our ninth annual sustainability report reflects who we are as a company. We believe that mining should always create value that lasts beyond mine life, empowering communities, protecting the environment and advancing human rights.

"Over the past 12 months, we strengthened our governance and long-term strategic capacity, expanded our global footprint, and reinforced partnerships that deliver real benefits, from better health care and education to biodiversity conservation and sustainable livelihood initiatives.

"This report highlights how sustainability guides our choices now, as well as shapes our future impact. The progress we made in 2025 is a testament to the dedication of our people and partners as we continue to build a mining legacy that future generations can be proud of."

The 2025 sustainability report aligns with leading global frameworks, including the Global Reporting Initiative's Mining Sector Standard 14 (GRI 14), World Economic Forum's Stakeholder Capitalism Metrics, Local Procurement Reporting Mechanism, International Council on Mining and Metals' 10 Principles, and the United Nations Global Compact.
