"2025 was a strong year for sustainability at Lundin Gold," said Jamie Beck, President and Chief Executive Officer.

Our first ESRS-aligned sustainability statement reflects the rigour we bring to measuring and reporting on these results, and our new 2026-2030 strategy reflects the maturity of our approach to responsible mining."
