History & Geology
A Journey Into the Silver Peak Range
June 2013 by Bill Rich
The Gold Rush in California called hundreds of thousands of souls to leave their homes to journey to the the far reaches of the West. At first the rich goldfields of the Sierra Nevada beckoned to these adventurous pioneers.The Wisdom of Mark Twain—And Tales of Cheating the Unwary Prospector
I (enjoy) Twain’s description of a gold mine, “A hole in the ground with a liar at the top.” Some humor here? You bet, but I’m sure he meant it to be a real eye opener as well.
Critical Minerals: Titanium—Part II
There are both hard rock and beach sand types of titanium deposits, but the hard rock deposits need to be at least 10 percent titanium while the beach sands often are economic with only two or three percent titanium.
Know Your District
We have to remember that the earliest miners were not geologists, but came from a variety of backgrounds. Their survival depended on finding enough gold so they worked hard and adapted to whatever challenges these new areas presented.

The Geology of Diamond Deposits
New theories have been developed and they may lead to new discoveries and give prospectors some new insight on where to look for diamonds.
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.
Perception of Mining vs. Reality
Many modern mining companies have taken to making a special effort to ensure the goods and services they need are supplied as much as possible out of the local economy.
