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.

Even with my favorite top-of-the-line gold detector there were several false digs. Many of the hot rocks gave a solid signal that was too much like a nugget to ignore. After trying several tests I just dug everything because it is better to be safe than leave a big, deep nugget for a more diligent gold hunter.

Gold trapped in the cracks can be encrusted close to the walls or mixed with sand and pebbles, making the gold difficult to see and then extract. Crevicing requires a lot of patience to achieve positive results.
