History & Geology
The Silver Islet Mountains of Utah
January 2014 by Alan J. Chenworth
I set up my dry washer on the north side of the cut and sampled the bed rock and dumps around me. As I was only sampling, I ran for 20-30 minutes, shoveling from a variety of areas.
Green Valley Gold District, Payson, Arizona
Most gold-bearing quartz veins found in the district were fracture fillings in faults enclosed by crushed quartz zones along their margins. Since the host rocks were often extensively weathered, portions of the veins stood out as positive, resistant outcrops. The gold-bearing veins ranged from a few inches wide to the vein at the Gowan mine that was as much as 12 feet wide. Gold Placers in Italy
Gold is a fairly widespread mineral in the Italian Alps and in the Northern Apennines. It is found both in primary mineralization and in past and recent floods.
One of the Richest Beaches Ever Mined
Everyone has heard of the golden beach at Nome, but Nome did not have the richest beach.
Understanding and Prospecting Benches
The most obvious benches are usually near the valley floor, but they can be thousands of feet above the valley floor. Since benches were made by streams, they can contain placer deposits.
Natural Gold Alloys
Natural gold is never 100% pure; all natural nuggets contain at least some impurities. We're going to take a look at just what some of those impurities might be.
All the Gold Ever Mined...
If you have been prospecting for any length of time, then you have probably heard something like, “All the gold ever mined would equal a cube 60 feet on each side.”
All About Lead Minerals, Silver and Gold
Many miners know that lead is very commonly associated with silver values, but the truth is that it is also associated with gold values in many locations as well.
