Finding Gold with a VLF Detector—Part III
June 2014 by Steve HerschbachThe higher the sensitivity setting, the louder and sharper the signal from a gold nugget or other metal target.
Looking around, I could tell that this was an old hand-digging. As I walked around the perimeter of the digging I could see shovel and pick marks scratched on the clean, hard clay and bedrock.
We’ve had two trips to the deserts of Nevada and explored mines and mill sites, hiked miles of ravines in California, and swung our detector coils over thousands of square yards of bedrock.
Picking the right spot to placer has to do with years of experience, and a little luck. The textbooks can tell you where it should be, but sometimes the rules just don’t seem to apply.
Just three weeks ago one of our prospecting team members decided to go back to this location on his own. He had a new detector and wanted to try it out some.
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.
Before I tell you what dredging backwards is, I’ll tell you why my team and I decided to give this very unconventional dredging method a try.
Because the old timers were so good at locating the better paying deposits—most of them along clay seams in this particular area—it makes good sense to try and locate these clay lines at old mining sites.
