Placer Testing with Large Samples
June 2000 by Dr. Ralph E. PrayOf all the difficult gold placer sites to evaluate, none can compare with trying to dig to bedrock through twenty or thirty feet of soaked overburden through which water is slowly seeping downgrade.
If we watch the action in six important markets, then we must conclude that there is, indeed, cause for deep concern.
The Gold Eye placer claims, located in the La Cholla district of Arizona, are still producing some beautiful gold. From the days of the Spanish explorers and Mexican miners, men have tunneled into the earth in search of gold in this area.
In 1893, Jerry McAuliffe led a team of prospectors east of Kalgoorlie in Western Australia and found the famed Kanowna goldfield. On their first day on the field, they picked up a total of more than 300 ounces of gold nuggets from the ground. As the rush began to increase in momentum, other prospectors found patches of nuggets simply lying on the ground near rich outcroppings of reef. In very quick time, hard rock miners were tearing into the rich reef lines...
First, let me say that Eldorado Canyon is what we call this area, but it’s not the real name. It’s a piece of private property where we have permission to metal detect; I do not want to start another gold rush! The property is located in Mariposa County...
Just three weeks ago one of our prospecting team members decided to go back to this location on his own. He had a new detector and wanted to try it out some.
So why would a modern-day prospector want to learn about a method of mining that was banned by the courts more than a century ago?
Once you have had a chance to look at our charts and quotes for this issue, I have one bit of advice. "Don't go running off to see your optometrist!"
