All About Pyrite
January 2015 by Chris Ralph
Most prospectors learn early that pyrite is fool's gold...but the truth is it can be an excellent indicator mineral for gold and in many cases does contain small amounts of gold.
The Pearce Mineralized Area, Dragoon Mountains, Arizona
...I would bet considerably more lode gold and silver remains to be found in this area, and there are possibilities for small placers and nugget shooting.
Strategic Metals—Part II
There are literally thousands of abandoned wasterock and ore dumps that dot the United States that could hold many tones of strategic metals.
Iron Ores and Iron Mining
For more than 40 years, iron ore prices have been decided by private negotiations conducted between the largest of the iron miners and the largest steel producers. These two sides dominate both the spot and contract iron ore markets.
Alaska's Cripple Creek Mining District
If developed with metal detecting in mind, this virgin ground could be a bonanza for nugget hunting.
Prospecting for Diamonds
Let’s take a look at diamonds and diamond mining and see how they form, how they are used beyond just jewelry, and what leads geologists to find diamond deposits.
Why Did This Silver Mine Close? - Pt III
