Remains confirmed as missing West Australian prospector

Mystery surrounds the fate of prospector Jennie Kehlet after her husband's remains were found at the bottom of a disused mine shaft.

Raymond and Jennie Kehlet, 47 and 49, had not been seen since they were prospecting in the Table Top area in the state's Mid West region on March 22.

The alarm was raised more than a week later when their dog wandered into the Sandstone caravan park, about 25km from their campsite.

Earlier this month, searchers found human remains at the bottom of a disused mine shaft.

Yesterday, police said they were those of Mr Kehlet.

Family members have been notified.

The couple's camp had previously been found, well-stocked with food and water.

Police have said the pair were not experienced prospectors but were capable campers.
