Following Clues to an Old Mill and Vein Strike
August 2012 by Don RobinsonMy last update on this adventure was in the April 2012 issue and involved our search for the northern extension of the Cedarberg Mine. At that time we had found it and we were in the process of returning for some detecting when Mother Nature struck with a late rain and snow storm.
That prospecting effort you are about to spend your time on...is it worth your effort? If you are going to devote your time to it, you will need all the facts you can get.
The type of mine dump that is best for metal detecting are the ones that consist of mixed sizes of rock and are located near some sort of excavation, commonly a shaft or adit. Sometimes the piles located along a trench dug by the miners can be productive as well.
Feeling through the mud, I felt the weight and shape of what could only be gold. Throwing my hand in the water revealed a sixteen-gram nugget oozing with character.
I suspect detailed geological mapping and prospecting would lead to discovery of one or more overlooked gold deposits in the district even though it has been heavily prospected in the past.
I poked my head out of the water and said, “You won’t believe what I am going to show you!”
...if you have a good, rich spot, hand-operated systems can produce some decent gold.
Knowing how to get the greatest depth performance out of your detector can be a handy thing, but it’s not an easy, simple matter.
