Study Confirms Mercury Levels Safe in California's Gold Country
July 2013 by Scott HarnWhile the Water Board documented the selenium levels in fish and noted they exceed the levels of mercury, they have yet to acknowledge the numerous scientific studies that show selenium effectively neutralizes the effects of mercury.
… I recently had the opportunity to sit down with Brent Weaver, Garrett’s chief design engineer to talk about gold-oriented detectors, how they work and how prospectors can get the most out of them.
Prospectors often wonder why gold deposits in veins like it does. Why is one vein rich while another is barren, even though they are only a few hundred feet apart?
There you’re expected to be personally responsible in making decisions, and yes, it can be costly. When you are responsible for your own life, you live life more, and with it you certainly risk more.
The placer gold shows up in ground sluice areas, hydraulic pits, secondary channels and hillside diggings. It is coming down the hillsides from an ancient channel left high and dry millions of years ago.
Because the old timers were so good at locating the better paying deposits—most of them along clay seams in this particular area—it makes good sense to try and locate these clay lines at old mining sites.
I remember in the couple of years after that 1997 flood, prospectors around California did very well, taking ounces of gold from places that had not yielded any gold for years before that.
We continue to seek out a patented mining property with an owner who is willing to host such an event with a water supply and enough remaining gold to make it worthwhile for the students.
