History & Geology
The Verde Copper-Gold-Silver-Zinc District, Jerome, Arizona
October 2012 by W. Dan Hausel
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.
Sulfides and Intergrain Gold Wire Nuggets
...these nuggets have not traveled far from the lode because the golden wire lattices would have been torn apart or flattened during weathering of rock and deposition by violent stream action.
The Wild Rush To Find More Cobalt—Part II
In this second part on cobalt, I will take a look at the various types of cobalt deposits and how you can prospect for them. Who knows—perhaps the next big cobalt strike will be yours.
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.
Sierra County Gold—Part II
...we will continue our examination of the rich streams and mining districts, and then take a look at some of the big nuggets that have been found here.
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.
The Silver, Gold and Gemstones of Candelaria, Nevada
The Candelaria area is of interest to prospectors not just for silver, gold and other metals, but also for the beautiful gemstones found there.
Weathering, Erosion and Placers
The big interest to prospectors thinking about the effect of erosion is not what might happen long into the future, but what they might find in the rivers later this summer when the water levels go down.
