In late July, a large sinkhole appeared near the town of Tierra Amarilla in Chile’s Copiapó province in the Atacama salt flat. The crater, which has a diameter of more than 100 feet, emerged in one of Chile’s most lucrative regions for copper and lithium extraction.
The nearby Candelaria mining complex—80 percent of the property is owned by Canada’s Lundin Mining Corporation and 20 percent is owned by Japan’s Sumitomo Metal Mining Co Ltd. and Sumitomo Corporation—had to halt its operations in the area.
