The truth is that cemented gravels are really not all that complex. There is no mystery of how gold grew there or somehow wormed its way into these solid gravels.
Only the famous Kennecott copper mine was able to continue operating through the Depression owing to the exceptional richness of its ore.
Q: Is this gold or some other metal?
The steeper the gradient is, the more potential erosive power to move gold and other bedload sediments, and the more power to remove obstacles to flow.
How rich does a hard rock ore have to be for it to be worthwhile to process and extract the gold?
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?
