Police say a man from Ear Falls is dead after the ATV he was driving plunged down a steep embankment on Stillwater Canada Inc.'s property near Marathon on Saturday afternoon.

In a news release issued Sunday, the OPP identified the victim as 63-year-old James Buckner — a contract worker for Stillwater.

Police said Buckner was driving the ATV on a downhill trail just before 4 p.m. on Saturday and missed a right turn to continue on the main bush road. The ATV went down an embankment and Buckner was thrown from the machine.  

Police added that he was not wearing a helmet.

Buckner was working at the time of the accident, and the Ministry of Labour will be investigating his death, according to police.  

An OPP collision reconstructionist has also been to the scene and conducted an investigation. Police said a post-mortem is scheduled to determine the cause of death.
