<div id="readability-page-1"><div>Capstone Copper Responds to Media Reports Pertaining to Mantoverde Operation Capstone Copper Corp. (“Capstone” or the “Company”) (TSX:CS) (ASX:CSC) is responding today to media reports pertaining to the status of operations at Mantoverde, where Union #2 continues with a strike commenced on January 2. During the evening of January 18, individuals entered the desalination plant facilities, located 40 kilometres from the Mantoverde mine, while workers were inside performing regular duties. Subsequently, interference with the desalination plant’s electrical system resulted in the interruption of water supply to Mantoverde. Striking union members are preventing access and the restart of facility operations at the desalination plant. At Mantoverde, on-site water reserves continue to be used for essential services. Sulphide operations are temporarily halted while oxide operations are expected to continue until tomorrow, at which point they will be temporarily halted unless water supply is restored. The Company is currently seeking judicial support to regain access to the desalination plant to restore water supply to Mantoverde and resume operations. Capstone Copper remains willing to engage in discussions to seek a resolution with Union #2. The Company will continue to adhere to legal procedures, respecting the rights of all its employees, inviting the union to engage in a constructive dialogue, and providing the authorities with all requested information. Capstone Copper is committed to the highest standards for integrity and transparency and looks forward to returning its focus to safe and responsible mining at Mantoverde, which brings great benefits to the workforce and surrounding communities.
