Glaciers and Placer Gold Deposits
November 2016 by Chris RalphIt also happens sometimes that glaciers will bury valuable placer deposits. This occurs when the glacier goes over the top of an existing placer deposit.
Epithermal deposits form in the ground at shallow depths. They are popular with prospectors because can yield very rich deposits and they are widespread in the Western US.
It is a gemstone, and yet it is also closely associated with many types of metal ores. It's valuable itself but often points toward other valuable minerals—that is certainly something prospectors want to know more about!
Most gold-bearing veins in this region are controlled by fractures associated with the Melones Fault, a late Cretaceous structure that is 108 to 127 million years old.
When prospectors and treasure hunters talk of gold in Arizona, it is the Lost Dutchman or Vulture mine they usually think of. The Lost Dutchman gold mine is just that—a myth chalked full of holes that has been embellished over time as any good legend should be.
There are a load of ways to do research, and I’m going to talk about how I do it—maybe you’ll get some ideas that will work for you, too.
To add to the confusion, the dam wasn’t holding back a large amount of water. It was full of gravels and had a small creek running through it. I had to know more.
You can learn a lot from a small mining operation because you have to become proficient in every job. Soon I was preparing fuses, placing powder (dynamite) and learning the ins and outs of drilling and blasting.
