In this case, signs of gold were found at the bottom of the alluvial and then traced in a triangle up the face of the mountain until they stopped—that is where the digging began.Unique Rare Earth Mine in Texas
Exploration for and prospecting in search of similar deposits should focus on rhyolite bodies located in fluorite-bearing areas.
All About Garnets
I get a lot of questions from prospectors about garnets, their value and what they tell us about the geology of some types of mineral deposits. So I thought it would be a good idea to take a closer look at the lowly garnet and learn a bit more about it.
How To Identify Minerals
There are a number of characteristics that are used when one identifies a mineral. Each characteristic gives an indication as to what the mineral might be, and the combination of them will point to what it is.
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.
The Significance of Nuggets in Placers
Chances are better that both types of gold did not come from the same source. Let's look at the probable conditions to cause two types of gold in a placer.
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.
Eastern Arizona: Gold and Base Metal Deposits—Part I
Arizona is well-known for its copper-gold porphyries and massive base metal-gold sulfide deposits such that primary gold deposits in the state are often overshadowed.
