The Goldfield Mining District -- Then and Now
March 2017 by W. Dan HauselIn 1983, some of the ore yielded more than 2,500 ounces of gold within 30 feet of the surface. The shoot pinched to a narrow vein.
There are literally thousands of abandoned wasterock and ore dumps that dot the United States that could hold many tones of strategic metals.
Only the famous Kennecott copper mine was able to continue operating through the Depression owing to the exceptional richness of its ore.
Even though these were some of the earliest placer deposits to be worked, there is still plenty of gold left today—it just takes more work to recover. Knowing about the old locations where gold has been found is the first step to success.
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!
Prospecting for lithium deposits can take a number of different directions, because this metal can be extracted from a variety of geologically differnet sources.
Because tungsten minerals are heavy, exploration can be done using stream sediment samples. Prospectors looking for gold have found scheelite or wolframite in their placer concentrates, and in some cases this has led them to make important tungsten finds.
The Beatty Mining District in south-central Nevada has been one of the most productive Mining Districts in the state, producing millions of ounces of gold together with silver, fluorite, mercury and other valuable minerals.
