Mr. Stephen Williams reports LUNDIN MINING REPORTS ON CIVIL CLAIM PERTAINING TO THE 2022 SINKHOLE AT THE ALCAPARROSA MINE Lundin Mining Corp. has received notice regarding the decision on the civil claim brought by the Chilean State Defense Council against Lundin Mining's subsidiary, Minera Ojos del Salado, related to the sinkhole that occurred near the company's Alcaparrosa mine in July, 2022. The decision requires Ojos del Salado to implement remediation activities on the impacted area, including, but not limited to, the backfilling of the sinkhole, the facilitation of recharging the aquifer, continuing monitoring requirements and the transfer of certain groundwater rights. In addition, Ojos del Salado is required to implement water infrastructure projects to strengthen rural potable water and waste water systems in communities surrounding the mine. Throughout the process, the company has collaborated with investigative proceedings initiated by sectoral regulators, including providing monitoring technology, studies and experts to provide information and ensure the stability of the sinkhole. The company will work with authorities and stakeholders to clarify details and timelines of the remediation activities included in the decision while it determines its next steps. Mining operations at Alcaparrosa have been suspended since the sinkhole incident occurred in July, 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.
