The massive 36-meter-diameter sinkhole that opened in late July in the commune of Tierra Amarilla, about 665 kilometers north of the capital, Santiago, received widespread global attention, prompting authorities to file charges against Lundin.
Research to determine the cause of the sinkhole is already at the “conclusive stage” and “technical agencies have already received all the information so that they can draw conclusions,” said the president of Lundin’s local unit. Luis Sanchez told Reuters.
Officials said that regardless of the outcome, the company plans to not only completely seal off the affected parts of the mine, but also fill the holes using materials such as sand and rock that have the same properties as the river bed. He said that
Sanchez declined to estimate the amount of materials needed or the total cost, but said the company has already spent about $10 million on solving the problem.
Officials said 300 to 330 liters of water per second were initially leaking into the mine, but lockdown efforts have reduced levels to 10 to 30 liters per second.

“We are seeing positive progress in restoring aquifer levels. I can say that we are not facing it,” Sanchez said.
The program will also attempt to pump the remaining 1.3 million cubic meters of water at the bottom of the reservoir in exchange for stopping other industrial users in the region from extracting those resources from the aquifer. , said Sanchez.
