A group of miners have shared disturbing photos of a 'UFO' they spotted in a remote region of Western Australia during an early-morning drive. 

The six workers were stunned when they saw the airborne object near Fortescue Metals Group's Solomon mine site in the Pilbara region at about 5am on December 7. 

The group spotted the strange object while driving from their laboratory worksite to catch a bus back to camp in the Hamersley Ranges.

According to one witness, it stood out clearly against the morning sky.

'There were six of us in the car,' the witness said.

'The people in the front noticed it first and commented that it looked weird.'

The driver initially thought the object was a cloud, but decided it looked more like a triangular UFO shape often seen in other sightings around the world.
