History & Geology
The Golden Streams of Butte County, California
May 2011 by Frank Lorey III
Even though these were some of the earliest placer deposits to be worked, there is still plenty of gold left today—it just takes more work to recover. Knowing about the old locations where gold has been found is the first step to success.The Golden Days of Julian, California
Some scattered reports say that gold may have been washed from streams here as early as the 1840s, but the undisputed major discovery came in 1870.
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.
Mineral Deposit Trends: Real and Imaginary
One of the most important things prospectors do is work to figure out where to go prospecting. Along with understanding the basic geology and putting yourself in a favorable area, one of the things a prospector might consider in finding a location to search is the existence of mining belts also known as mineral deposit trends.
Gold in Tertiary Gravels
In some places, semi-continuous sections of riverbed can easily be linked in many places to identify the path of the ancient rivers.
Gold, Quartz & Chalcedony—Part II
The specific gravity of chalcedony is 2.58 to 2.64. This is slightly lower than coarsely crystalline quartz because of slight porosity in chalcedony. Being so light, it will easily wash out of a gold pan.
Eastern Arizona: Gold and Base Metal Deposits Part II
In this review of precious and base metal deposits in Arizona, it is apparent that several significant mines and mineral deposits occur in eastern Arizona, and there is considerable potential for new discoveries.
Prospecting for Nickel Deposits
The periodic exploration efforts for nickel during periods of high prices have been sporadic and incomplete. There is a role for the prospector and geologist in searching laterites potentially rich in nickel and mafic igneous bodies that may be rich in nickel.
