Listen to the news
  • In late November 2025, Lundin Mining Corporation announced that the Supreme Court of Canada upheld a 2023 Ontario Court of Appeal decision allowing a securities class action to proceed over the timing of disclosure of a 2017 pit wall instability and rockslide at the Candelaria Mine in Chile.
