The landslip also damaged water and concentrate pipeline and it will take days before the pipes are restored.
Ok Tedi managing director and CEO, Peter Graham, said they hope to have the road cleared by the end of today to allow access for light vehicles into and out of the mine.
“It will take us another day or so for buses to move across. It may take us up to several days to a week to cut the pipelines and we’ll get specialist welders to reinforce the pipelines,” he said.
Graham said they are working around the clock to address the landslip.
