New Zealand police said Wednesday it captured images of human remains of at least two people 11 years after a coal mine explosion in the country trapped and killed 29 workers.

Police said in a statement that the remains, reviewed by experts, were captured in an area far from the Pike River mine and will not be recoverable because of the location’s remoteness.

“At this point we have been unable to identify the remains, however, we will consult with forensic experts. Based on our investigation we believe there were six to eight men working in the area where the remains have been located,” Superintendent Peter Read said at the release.
