Chile orders Lundin copper mine to close after massive sinkhole

The environmental regulator of Chile said that Canadian mining company Lundin will have to permanently close the Alcaparrosa Copper Mine in Chile after a sinkhole opened up near the mine in 2022.

Lundin had stopped work on the site when a sinkhole of more than 60 meters in depth opened up in the Tierra Amarilla Village in northern Chile. However, it had pushed for the restarting of mining at Alcaparrosa.

The SMA regulator in Chile said that they had determined that Lundin is responsible for the sinkhole and that the company must close the mine. They also fined the company $3.41 million.

Lundin operated in unauthorized areas, including the Copiapo River aquifer. This allowed for more water to seep in, causing the rock mass to weaken.

She added, "The company has caused irreparable damage to the environment."

In a press release, the local miner's unit, Ojos del Salado said that it will review the ruling to determine its next steps. $1 = 984.0500 Chilean Pesos (Reporting and writing by Alexander Villegas, Fabian Cambero and Kylie Madry. Editing and proofreading by Anthony Esposito and Sarah Morland).
