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.
In October, five of us decided to take an exploration trip into an area called Green Valley. This was perhaps ten miles upstream from where we had gone in September and the difficulty was access. One would think that based on the name it was an easily accessible area not far from a nearby town. This couldn’t be more wrong.
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.
I had some success following this premise this summer, finding a few nuggets in places I think I overlooked in the past.
In some places valuable ores can be found within the waste material of mine dumps, sorted ore piles, and detrital vein matter at the surface. Though many of these old mine sites can be an excellent source of gold, not all are created equal.
The research I did for “Gold in the Slate Creek Basin” (September 2011 issue) found me chasing a channel out of the LaPorte territory headed towards the old mining town of Brandy City, California.
The mysteries of this spot were only just starting to develop. There is nothing but very bland granite-type rocks here, meaning no bold, favorable indicators.
When I was recently in West Africa, I got to see and play with my first, phony, Chinese knock-off metal detector.
