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.

The question I had, and likely you have too, is when an old channel is cut, how far does the placer gold in the cut channel move down in a river or creek that continues to erode deeper and deeper?

There is a material processing principle widely used in large milling operations to improve recovery that is poorly understood by most of the micro-mining and prospecting community...

My hunch was that the gold is coming down the apron, falling off to both sides and into both gulches. I say that because the gold we found previously has the same characteristics and color across the entire area.
