Lundin Mining Announces Approval of Candelaria 2040 Environmental Impact Assessment

VANCOUVER, BC, Sept. 11, 2023 /PRNewswire/ -- (TSX: LUN) (Nasdaq Stockholm: LUMI) Lundin Mining Corporation ("Lundin Mining" or the "Company") is pleased to announce that the Environmental Impact Assessment ("EIA") for the extension of operations and mine life for its Candelaria Copper Mine in Chile (the "Candelaria Optimization and Operational Continuity 2040 EIA") was approved by the Regional Environmental Commission of Atacama ("COEVA") on September 8, 2023. Issuance of the Resolución de Calificación Ambiental ("RCA") by Servicio de Evaluación Ambiental de la República de Chile ("SEA") is anticipated in October 2023.

The Candelaria Optimization and Operational Continuity 2040 EIA considers several enhancements to the current operation that will enable the extension of the mine life to 2040, from 2030 under the previous EIA, and includes various measures that will support sustainable social, economic, and environmental development within the Atacama Region. The EIA was submitted to the authorities in February 2020. Approval represents a key milestone towards successfully extending the operational life, including development of the La Española open pit, as presented in the February 2023 technical report titled "Technical Report for the Candelaria Copper Mining Complex, Atacama Region, Region III, Chile." The Candelaria Optimization and Operational Continuity 2040 EIA also allows for the potential development of the Candelaria Underground Expansion Project ("CUGEP") not included in the February 2023 technical report.  

Peter Rockandel, CEO of Lundin Mining stated, "We are very pleased to announce approval of the Candelaria Optimization and Operational Continuity 2040 EIA. This announcement is the culmination of a comprehensive process and reflects our long-term commitment to our employees, our communities, the region, and the country of Chile. Approval enables the construction of various facilities and initiatives that, together, represents continued investment and local employment. We are excited to continue working together to create a prosperous and sustainable future in the Atacama Region."
