The hole, 25 meters in diameter, occurred near the town of Tuerra Amarilla in a mining area, and authorities are trying to determine why, The Guardian reports.
The National Service of Geology and Mines (Sernageomin) learned Saturday of the existence of the pit, located on land exploited by the Canadian company Lundin Mining, about 665 km north of the capital Santiago.
Specialized personnel were sent to the site, said the agency’s director, David Montenegro. “It has a considerable depth, about 200 meters. We have not found any material down there, but we have noticed that there is a large amount of water,” Montenegro added.
After the emergence of this huge pit, several areas at the entrance of the Alcaparrosa mine, located near the pit, were closed, Sernageomin said. Lundin Mining said Monday that the incident had not affected workers in the community, but that the pit had not been altered since its discovery.
“The area was immediately cordoned off and the appropriate regulatory agencies were notified. There was no impact to personnel, equipment or infrastructure,” the company said in a statement.
Lundin Mining said an engineering analysis is underway to determine the cause of the event.
“The nearest house is more than 600 meters away, while any inhabited area or public facility is almost a kilometer away from the affected area.
