Authorities have resumed a land-and-air search for a prospector missing in Western Australia's Goldfields region.
Police and emergency services have been searching for 46-year-old Michael Graham in remote bushland, north of Menzies, for almost two weeks.
Mr Graham was last seen prospecting with his friend Pete Holloway, who says he woke up one morning to find him gone.
"I took off because I thought he [had] the jump on me," Mr Holloway said.
"You just hope he shows up - your hopes are always up when you hear good news on the radio."
Mr Graham has not been seen since, but hopes were renewed a few days ago when a station owner found SOS messages and personal belongings.
Police say they will start using off-road motorbikes to help search efforts.
