Detecting: Getting Away From The Heat And Into The Gold
August 2020 by Ray Mills
Within a very few minutes, I had my first nice sounding target. It turned out to be a nice earring-size gold piece that was about a half a gram.
It is better in a gem and mineral mining operation that the driller, blaster and mucker be the same person in order to be able to predict placement of the desired mineral enriched pockets.
There weren’t as many pieces of gold, but what I did find was bigger. As I worked my way down towards the spot that I had been working the first three days, I noticed a large crack that crossed the river.
His findings were not exaggerated—after running 82 buckets of gravels in two days we had a remarkable 27.8 grams of gold!
We chose this particular area because an old channel had run here at one point and had been heavily worked on top of a mountain hilltop. Erosion patterns cut deeply on each side, leaving the channel exposed. The erosion cut sharply, dropping into ravines far below.
"Suh-wheet!" I exclaimed as I sprang to my feet and quickly pumped my detector coil high overhead to alert Smokey that I had just found a nugget.
The mine site consists of river gravels from an ancient channel covering over 20 acres, and the place is covered with very large river rock and small tree overgrowth.
These gritty clay lines were only a quarter of an inch up to three inches wide. Once the line had been laid out, they would look at the wall of gritty clay material and seek more indicators.
