LUNDIN MINING PUBLISHES 2022 SUSTAINABILITY REPORT

Lundin Mining Corp. has published its 2022 sustainability report.

"Our 2022 Sustainability Report highlights many examples of the meaningful work we are undertaking to ensure Lundin Mining continues to exceed the evolving demands of our business and stakeholder expectations while supplying the world with metals vital to a low carbon future," said Lundin Mining's Chief Executive Officer, Peter Rockandel. "We are especially proud of our Candelaria operation for being awarded The Copper Mark(TM) certification, a voluntary program that recognizes copper producers for their demonstrated commitment to responsible operating practices, following an extensive assessment process in 2022."

"Our operations continue to make great progress in the implementation of our Focused on the Future sustainability strategy. A great example of this was the finalization in 2022 of site-specific roadmaps to achieve our interim decarbonization target of a 35% reduction in Scope 1 and Scope 2 emissions by 2030," commented Kristen Mariuzza, Senior Vice President, Sustainability, Health & Safety. "We are also very excited about the level of engagement and accelerated rollout of Fatal Risk Management (FRM) across our organization. FRM is an industry-leading fatality-prevention program that focuses on the fatal risks present in mining. By recognizing the fatal risks, implementing critical controls and workplace planning that integrates FRM into everything we do, we are on the path to our commitment of Zero Harm."
