A land search is underway after a man went missing while prospecting in the Goldfields.
Victorian Adam Galvin, aged 45, had been reported missing by his friend saying he'd last seen him near Carosue Dam, 150km north-east of Kalgoorlie.
Police had searched the general area to try to find the man.
The search has now since escalated with an aerial search helping, along with members of the SES.
Concerns are held for the person as there is no knowledge of whether he has food or water.
The search for Mr Galvin will continue into the evening and overnight, with plans being made for more searching tomorrow morning if he has not been located by then.
Anyone who has spoken to Mr. Galvin in recent days is asked to contact police on 131 444.
