Don’t walk away from a weird target. I went back to a spot I found late last year that left me somewhat confused. This small area of exposed bedrock sounded off as a strong target with my GPX4500 but not a peep with my Eureka Gold VLF. At first I thought it was a strange hot rock area, but with no response from the VLF (a notorious hot rock detector), I was perplexed. To make matters worse, no matter what timing setting I tried on the PI, it still registered as a target in solid rock. The fact that the VLF didn’t respond made me think the target might be beyond the depth sensitivity of that machine so maybe a second look at this spot was in order. …Turns out that this was correct. The target was located in a small garnet-laced seam (about 6 inches wide) sandwiched between limestone bedrock. I managed to convince my much more “motivated” son to chip away at this garnet seam with a mallet and chisel for a few hours until he broke through to a small, red clay-filled cavity located underneath; about 7-10 inches down. There we found many delicate, paper-thin pieces of gold locked in the clay. To date, we recovered about 3 grams of the good stuff but I’m still panning out the clay from the hole. I’ve never seen this type of leaf-gold in this area. I wonder if it was originally formed in a hydrothermal event with the gold being deposited between cracks in the garnet rock. But over the years, maybe the rock in this pocket deteriorated into this red clay stuff leaving the gold still trapped in it? Here are some pictures of our finds, and my son’s handy excavating work.
