Chile Fines Lundin for Sinkhole
Chile’s Ministry of Mining said the subsidence occurred in the underground galleries of the Alcaparrosa. The DGA is the first service to close an investigative process in accordance with its powers and to issue a fine. It also ordered the mine to design a monitoring system and develop a follow-up plan for the underground water system within 45 days.
Lundin Mining has two options: pay the fine within 30 business days, or file an appeal for reconsideration. The company said it is performing its own investigation. They also said that, since July, they have been focusing efforts to minimize the impact on employment due to the suspension of production and to develop a engineering project to stop the infiltration of water at the Alcaparrosa mine. The mitigation plan would also address the effects of the sinkhole. The central objectives are to fill the sinkhole and dewater the mine.
