Chile seeks to punish those responsible for the sinkhole near the copper mine

Chile seeks to punish those responsible for the sinkhole near the copper mine

The mysterious 36.5-meter (120-foot) crater that appeared in late July prompted local authorities to mobilize and prompted mining regulator Sernagomen to suspend operations of a nearby Lundin-owned Canadian mine in the northern Candelaria region.

“We will move forward with the consequences and penalties, not just the fine,” Mining Minister Marcela Hernando said in a press release, adding that the fines were insignificant and the sentence should be “exemplary” for mining companies.

The Chilean authorities did not provide details of the investigation into the causes of the sinkhole.

Local and foreign media showed various aerial photos of a huge crater in a field near the Lundin mining operation, about 665 kilometers (413 miles) north of the Chilean capital. Initially, the crater, near the town of Tierra Amarilla, was about 25 meters (82 ft) wide, with water visible at the bottom.

The Canadian company owns 80% of the property, while Japan’s Sumitomo Metal Mining Co Ltd and Sumitomo Corp.

The minister added that although the country’s mining regulator had conducted an inspection in the area in July, it was not able to detect “over-exploitation”.

“It also makes us believe that we have to reformulate what our inspections are,” she said.

Lundin said in a statement that the excessive exploitation indicated by the minister had been reported.

“We want to stress that, to date, this hypothesis has not been identified as cited by Cernagomen as a direct cause of drilling. Hydrogeological and mining studies will provide the answers we are looking for today,” Lundin said.

“Various events that could have caused the crater are being investigated, including the abnormal rainfall that was recorded during July, which is relevant,” Lundin added.
