Within this area, about two million ounces of gold and fifty million ounces of silver have been mined. Faults, dikes, veins and fissures that carry the ore form a concentric radial pattern—like spokes on a wagon wheel—around the caldera core.
Because these crevices catch and hold gold so well, it's worthwhile to learn how they form, which ones are good for catching gold and which ones are not.
It is not necessary to have a PhD in geology, but you need to know the basics, so that’s what I am going to try to dig into here—the understandable basics of these gigantic gold deposits.
I thought things started off okay until I realized I had forgotten some of my gear and had to return to the house. My troubled start was not helped when my boy came up to me a few minutes after my return to show me his first nugget of the day.
“The evidence is clear—mineral deposits alone are not enough to attract precious commodity investment dollars...”
Many years ago I was in the American Canyon. I remembered a few details about a placer deposit there, so we decided to make a trip down and re-check some of these old workings.
...if you have a good, rich spot, hand-operated systems can produce some decent gold.
The big moment finally arrived. With Norm suited up, I pulled the motor to life and felt instantly better. There’s really something relaxing about the sound of a dredge running—they don’t sound like anything else.
