Humans remains have been found in the Pike River Mine.
Experts have found at least two bodies in the deepest part of the mine. However, they can not be recovered.
The bodies were found using images from boreholes drilled from the ground. Some images even suggest the possibility of a third body as well.
Police are working with forensic experts to see what they can do to confirm identities.
