Bedrock Gold: When It’s There and When It Isn’t
February 2018 by Chris Ralph
Has your experience ever led you to wonder why some gold is deposited on bedrock and in crevices, while other gold is not? We’re going take a deeper look at this and see what we can figure it out.
We’ve had two trips to the deserts of Nevada and explored mines and mill sites, hiked miles of ravines in California, and swung our detector coils over thousands of square yards of bedrock.
Most dry washers have a feed rate adjustment. It needs to be set so that the material flows evenly over the riffles and does not bury them.
With the high price of gold, there are many new prospectors out in the hills all over the United States, and while we would all prefer to be finding those larger nuggets, it doesn’t always work that way. Sometimes all that is available is nothing more than a few small flakes. The truth is, new prospectors are sprouting up all across the planet—especially in the developing nations.
Joy was written on his face, holding up the nugget—his first ever nugget—that he and his grandpa dug up together.
Our research indicated this whole area had been claimed by Newmont mining company for several years, but when the price of gold dropped they let the claims expire, and we confirmed this with the local BLM office.
The holes were overloaded with explosives, but I didn’t know it. I was just a green mining engineer fresh out of school and told to watch as the experienced miners set the charge.
