A retired gold prospector spent hours digging up his fortune in the northern goldfields near Kambalda, Western Australia, after finding the target with his metal detector.

The pit was a classic one—exposed shale bedrock with all the material being washed out one end of the pit. Within a few minutes I had a nice mellow signal that was in open ground.

There is a major change coming in the economy of the world and now is the time for prospectors and miners to grab a ticket and get on board.

The old timers typically washed these areas down to bedrock, and some areas appear terraced. I would imagine this is because these hydraulic mines were generally where the miners found old Tertiary river channels on the sides of mountains that were gold-bearing.
