Iron Minerals, Your Detector and Gold
January 2013 by Chris RalphIt’s worthwhile for the prospector using a metal detector to know a little bit more about the association of iron and gold as well as how iron minerals affect your metal detector.
Every year there are large nuggets found by the diligent, and occasionally by the lucky newbie.
...I decided to excavate the semi-frozen high-bank that was resting on a soft shale bedrock footing. Within three feet, I encountered an intrusive!
Normally the detector he was using would sound off with a definitive high-to-low tone when passed over a piece of gold, which distinguished the gold from the many high iron content "hot rocks," but this one was different...
As I laid in my Jeep and tried to get some rest, I began to realize how tired I was. I felt like a little kid who walked around Disneyland for 12 hours with his parents.
It was down deeper than I expected for surface trash. It wasn't until I was down six inches that the target screamed from my scoop.
…the “One More Time” has turned into three more trips and each of the three has yielded more gold each time down.
Over the years that I have been detecting for gold I have had many of the same questions come up. I decided to write this article to hopefully answer some questions that a person wishing to detect for gold may have.
