All the Gold Ever Mined...
February 2012 by Chuck LassiterIf you have been prospecting for any length of time, then you have probably heard something like, “All the gold ever mined would equal a cube 60 feet on each side.”
For the prospector, knowing what oxidized hydrothermal alteration looks like in the field is an important exploration tool.
The small-scale miner has reasonable opportunity to exploit some of these small, rich placer gold deposits.
I would first like to mention that I am not a geologist. I have, however, spent the last 8 years intently searching for gold nuggets with a metal detector. I have found gold in numerous locations, and in several different types of gold deposits.
Gold, on the other hand, is super rare, and is one of the rarest elements in the earth’s crust. It averages only 0.000004 percent of the earth’s surface. That is four parts in a billion.
Sulfides and oxides—what's the difference between the two?
Many prospectors thought that Nevada was all prospected out following all the rich discoveries of the 1860s and 1870s, and what was there to be found had already been found.
