Water drilled from rock in a North American mine is among the oldest yet found on Earth, say scientists.
Novel dating techniques used by the Canadian and UK team suggest the fluid is at least 1.5 billion years old.
The water was probably once on the surface and then percolated through the ground where it became trapped at a depth of 2.4km.
