Jadeite in California
April 2015 by Bill Rich
...two jadeite locations in California have been thoroughly researched by geologists. There are no doubt others that lie in wait.
The Oquirrh Mountains, Utah
...we will visit three dormant mining districts that lie in the Oquirrh Range in Utah. Some major activity that transformed the lives of thousands of people occurred here from the mid 1860s to the late 1990s.

Large Gold Deposit Types
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.
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. California: The Land of Big Nuggets—Part I
The nugget sat there in plain sight, though it was covered in dirt, while hundreds of people had passed that way every day.
Nevada's Silver City Gold District—Part I
The name Silver City is quite ironic as it doesn’t really fit the area’s metal production. The area encompassing the Silver City district is a great, stand-alone gold district, where the production value of gold has been much more than that of silver. Since the initial discovery of gold-bearing veins in the mid-1850s, the area has been a center of continuous small and large-scale gold production.All About Quartz—Part II
In our May 2013 issue, we took a look at the mineral quartz, a mineral very commonly associated with gold. However, gold is not the only reason prospectors are interested in quartz. Quartz can also be very valuable as a gemstone
