Gold in Beatty, Nevada
September 2013 by C.A. "Charlie" CookIn this case, signs of gold were found at the bottom of the alluvial and then traced in a triangle up the face of the mountain until they stopped—that is where the digging began.
Colorado Uranium Mining in the 1950s Boom
You can learn a lot from a small mining operation because you have to become proficient in every job. Soon I was preparing fuses, placing powder (dynamite) and learning the ins and outs of drilling and blasting.
The gravels in contact with the bedrock or false bedrock base are often the richest. The same facts apply to the alluvial paystreaks that are formed on gravel bars; the lowest level of the gold-bearing gravel is normally the richest.
Residual Placers: An Often Overlooked Gold Source
Because the forces of erosion and gravity tend to carry lighter materials like quartz away more easily, the heavy minerals like gold or silver will tend to be concentrated in the general area around the vein outcrop. These concentrations are what make residual placers so attractive.

The Coolgardie Gold Mining Camp of Southern California
The area was mined intermittently from around 1900 to 1915, but was also mined in the late 1800s, with a total output valued at about $100,000, which is around $9.5 million at the current gold price.
Strategic Metals—Part I
A bill was introduced and passed by the House of Representatives earlier this year that should make the exploration and opening of a mining operation faster and easier.
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.
