History & Geology
The Pearce Mineralized Area, Dragoon Mountains, Arizona—Part II
August 2013 by W. Dan Hausel
There are many prospects within the known mineralized area and along the margins of the mineralized area that should be examined for gold and silver.Glaciers and Placer Gold Deposits
It also happens sometimes that glaciers will bury valuable placer deposits. This occurs when the glacier goes over the top of an existing placer deposit.
Jadeite in California
...two jadeite locations in California have been thoroughly researched by geologists. There are no doubt others that lie in wait.
The Verde Copper-Gold-Silver-Zinc District, Jerome, Arizona
When I was a student in the College of Mines at the University of Utah, the Verde district was used as an exploration model for “submarine volcanogenic massive sulfide deposits.” So I looked forward to visiting this district and the town of Jerome in central Arizona in the spring of 2012.
Electrum: Gold and Silver Together
...if you are out prospecting and find something that looks very much like a nugget but has an odd greenish-gray cast to it, don’t be too quick to simply toss it aside as junk.
Exploration Rush at Tonopah, Nevada

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 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.
