TSX: LUN) (Nasdaq Stockholm: LUMI) Minera Ojos del Salado, a subsidiary of Lundin Mining Corporation ("Lundin Mining" or the "Company") has received a notice from the Superintendencia del Medio Ambiente ("SMA") following its investigative proceedings involving the sinkhole that occurred at the Alcaparrosa mine in 2022. The notice levies a fine of $3.3 million and orders the continued closure of the Alcaparrosa mine, based on four violations investigated.

Mining operations at Alcaparrosa have been suspended since the incident occurred in 2022. At the time, Mineral Reserve estimates for the Alcaparrosa mine were removed from the Company's reserve statement and have not been included in any future production estimates. The Company's Candelaria operation is unaffected and generated record production in the second half of 2024. The Candelaria mine is forecast to produce 140,000 tonnes to 150,000 tonnes of copper in 2025.

The Company has collaborated with investigative proceedings initiated by the national environmental regulator (SMA), including providing monitoring technology, studies and experts to guide the process. The Company will review the notification and determine the next steps relating to the charges that it allegedly breached its environmental permit at its Minera Ojos del Salado operation which owns the Alcaparrosa mine.
