Coeur Publishes 2024 Responsibility Report

Coeur Mining, Inc. (“Coeur” or the “Company”) (NYSE: CDE) today published its 2024 Responsibility Report (the “Report”), highlighting the Company’s commitment to advancing environmental stewardship, community engagement, ethical governance and responsible mining operations. The Report outlines Coeur’s public sustainability targets and management practices that aim to drive long-term value creation for stakeholders.

Report highlights include:

• Water Management – In 2024, Coeur conducted water vulnerability assessments to evaluate evolving water-related risks and determine both existing controls and additional measures required. Additionally, the newly acquired Las Chispas mine has implemented water initiatives to support the surrounding community, including a $1.5 million investment in sustainable water infrastructure and collaborative development of a five-year water stewardship plan. These combined efforts are expected to help create a resilient water management system and deliver significant community benefits
• Health and Safety – Coeur maintained its industry leadership in employee safety by focusing on leading indicators to reduce repeated exposure and long-term risk, achieving the lowest employee total reportable injury frequency rate among its peers at its U.S. mines for the third year in a row¹
• Tailings Management – As part of Coeur’s commitment to implementing the Global Industry Standard on Tailings Management, the Company completed 20% of the outstanding tasks required for implementation across all sites in 2024
• Biodiversity Management Standard – The Company furthered the implementation of its Biodiversity Management Standard with the completion of a nature-related risk assessment at its Kensington mine. In 2025, Coeur plans to expand implementation to its recently acquired Las Chispas operation and conduct assessments at additional operating sites
• Climate Resilience – The Company exceeded its goal of reducing greenhouse gas (GHG) net intensity emissions by 35% compared to its base year², accomplishing a 38% reduction
• Strong Governance – The Company refreshed its corporate responsibility materiality³ assessment to maintain alignment with evolving stakeholder priorities and reinforce robust governance

"At Coeur, we understand that sustainability and long-term value creation are fundamentally interconnected,” said Mitchell J. Krebs, Chairman, President and Chief Executive Officer. “The progress we made over the last year, including the successful expansion of our Rochester operation, the acquisition of the high-grade Las Chispas mine and delivering accelerating free cash flow and debt reduction, reflects our commitment to sustainable growth, operational excellence and financial strength. We are strengthening our business through continuous advancements of our health, safety and environmental management systems, reducing our greenhouse gas emissions intensity and investing significantly in exploration. Our approach helps us build a more resilient company that delivers strong operational and financial performance, while also enabling us to play a meaningful role in providing the metals essential for a cleaner, more connected world that delivers lasting value for all of our stakeholders.”
