I love it when I am in the middle of a high trash area and all the ferrous bars go away, the screen number goes to a three or an eight, and the meter is forty to a hundred. I don’t know for sure that I have found gold, but it narrows the odds down.

The concentrate is just the heaviest of the heavy minerals but some sulfides are sneaking in there also with the gold...

This same concept is true of many of our modern-day rivers, and we have to find out where their gold originated if we can.
