California's Mother Lode Quartz Veins
May 2015 by Chris Ralph
The actions of the hot, ore-bearing solutions are not limited only to the deposition of material within the walls of the fissures.
Greenstone and Gold
Contacts, faults and zones of weak rock are all places that can act as a pipeline to convey gold-bearing fluids, leading to valuable deposits.
Northwestern Alaska Mineral Resources
Gold and jade are actually only minor mineral resources for the Northwestern Alaska region as a whole. Modern prospecting has focused more on base metal than precious metal resources.
The Goldfield Mining District, Nevada—Part I
An example of some of this extraordinary ore was a lot of about four tons from the Florence mine during the last days of a lease that averaged over 300 ounces of gold per ton.
All About Native Silver
Some of the wire forms are strange and fantastic, with wires sticking out in twisted, seemingly random directions. Others have deformed crystals and all of them have significant value to collectors.
The Birimian Greenstone Belts of West Africa
The country we were to visit was Burkina Faso, a small country about the same size of my home state of Nevada with about 10 times more people. The second day I was in Africa, we went out to the goldfields for the first time.
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—Part II
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.
