Sanders claimed he used ground-penetrating radar to survey his private property in Nevada County, California, and uncovered the chunk of gold with a backhoe when he was following up on one of the anomalies found by the radar.

Across and downstream of our operation was a large pile of huge boulders. It was logical to think that water forces may have deposited gold in and around these boulders. We moved our dredge over and started pulling the rock pile apart.
Within this area, about two million ounces of gold and fifty million ounces of silver have been mined. Faults, dikes, veins and fissures that carry the ore form a concentric radial pattern—like spokes on a wagon wheel—around the caldera core.
Our theory was that a dredge would collect far more material in a shorter period of time, leaving us with ounces of gold every day.
I had two of the guys go down into the creek and each one picked out a small island of bedrock. I had them detect their piece of bedrock and then gave a critique to all on how they did.
