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, ongoing monitoring requirements and the transfer of certain ground water rights. In addition, Ojos del Salado is required to implement water infrastructure projects to strengthen rural potable water and wastewater 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. The Company's Candelaria operation is unaffected and is forecast to produce 140,000 tonnes to 150,000 tonnes of copper in 2025.
