The search for a missing prospector in WA has been renewed after a Goldfields station owner discovered makeshift camps and SOS notes left by the 46-year-old man.
The West Australian reports the station owner made the discovery outside a trough shed at the Five Mile windmill, 15km from where Michael Graham was last seen.
Rescuers found SOS hacked into the dirt at the remote windmill, and 5km down a road the words “walking” and “very weak” had also been scraped into the ground.
A further 5km east police found a line drawn across the road, a second SOS message, and an arrow pointing west.
According to The West Australian station owner Don North also found a makeshift camp 500m north of the windmill, with a shelter made from an old swing-set and empty cement bags.
Earlier this week part of Graham's family flew into the remote Goldfields site near Menzies to help the search effort.
It is believed Graham wondered off from camp during the night without water or navigation equipment.
Graham has been missing for 12 days, and the tactical response group has now taken over the search effort from State Emergency Services volunteers.
