TORONTO, ONTARIO–(Marketwired - March 25, 2015) - Lundin Mining Corporation (TSX:LUN)(OMX:LUMI) (“Lundin Mining” or the “Company”) notes that mining and milling operations at its Candelaria and Ojos del Salado Mines, near the city of Copiapo, Chile have been temporarily suspended due to recent heavy rainfall and flooding that has affected power and access to the site.

Over the last 24 hours there have been abnormal rains in central and northern Chile, with the Copiapo region being particularly affected. The Copiapo River and lower lying communities down the valley from the mine have experienced heavy flooding in numerous locations. This flooding has closed provincial roads, disrupting access to the Candelaria Mine. No significant damage or injuries have been reported at the Candelaria mine site.

A further update will be provided once the impact of the flooding on regional infrastructure is better known.
