A prospector who went missing in the WA Goldfields last week is still yet to be accounted for, and family members have flown into the remote site to help the search effort.
State Emergency Service volunteers, a search helicopter, and mounted police have been searching for missing prospector Michael Graham since early last week.
It is believed Graham, 46, wondered off from camp during the night without water or navigation equipment.
Emergency services said abandoned mine shafts were now being searched and sniffer dogs might also be called in to help with the effort.
Graham was last seen 10pm Sunday while camping with his friend Peter Holloway 70km north-east of the Goldfields town Menzies.
