History & Geology
The Pearce Mineralized Area, Dragoon Mountains, Arizona
July 2013 by W. Dan Hausel
...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 Ups and Downs of Geologic Faults
Faults are fractures, breaks and broken zones in the Earth’s crust where one side of the break has moved relative to the other, and they come in many different varieties.
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.
The Giant King Mine
Most gold-bearing veins in this region are controlled by fractures associated with the Melones Fault, a late Cretaceous structure that is 108 to 127 million years old.
Undiscovered Placer Deposits in Alaska
These conditions don’t just apply to Alaska and the Yukon; they apply to western Canada and even to the mountainous western United States.
Epithermal Gold and Silver Deposits
Epithermal deposits form in the ground at shallow depths. They are popular with prospectors because can yield very rich deposits and they are widespread in the Western US.
Detector Brings New Life to An Old Lode Mine
…it was immediately evident the previous owner had not been using a detector. During just a few months of working the dumps part-time, he recovered gold in quartz specimens valued in excess of $40,000.
Reese River Silver Mining District, Nevada
The strike and the dip of the veins can be broken down into two categories: veins in the eastern area and along Lander Hill, and the veins in the southwestern portion of the district.
