Kennecott Utah Copper has confirmed that a landslide at its Bingham Canyon Mine earlier this month has covered the mine’s main ore body and will need to be removed.
Ground movement monitoring alerted the mine operator to the risk of a landslide on 10 April allowing it time to evacuate its staff and move some equipment before the 150M.t landslide started at 9.30pm.
The mine has said that the landslide was a progressive failure on the north east of the pit occurred on a fault line.
Speaking at a press conference last week, Kennecott Utah Copper CEO Kelly Sanders said that his team had only just gained access to the bottom of the pit and are currently assessing damage to equipment. He said that the geotechnical assessment of the slide is likely to take the next month and confirmed that the material will need to be removed in order to return the mine to full operation.
