Metal Detecting Old Hard Rock Mine Dumps
May 2018 by Chris Ralph
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.
As a guide to those who are thinking of taking up this activity or those who currently practice this trade, I have created a listing of the primary tools and equipment I use when nugget hunting.
Walking around the gulch and exploring the upper drainage, picking up different rocks and inspecting them with a good loop, and looking them up in a field guide of rocks and minerals of your region will help you understand how the gold got there.
While the Water Board documented the selenium levels in fish and noted they exceed the levels of mercury, they have yet to acknowledge the numerous scientific studies that show selenium effectively neutralizes the effects of mercury.
I recently grew complacent, and it caused me to make a mistake that resulted in the loss of a mining claim. It brought my mining plans for the summer to a complete halt.
At first, I tried to shift things around, but then a hand with a rock would appear, so I would stop trying to adjust my gear and grab the rock to keep things moving.
I love to see old-timer workings while I am out detecting for gold. For one thing, it assures me that gold came from there. Second, it tells me gold should almost certainly still be there.
Mike and I each selected a side of the creek and started to work our way upstream. We both worked the water and sides of the creek, and better than half the gold found in this area is in the water.
