Welcome to the forum. I see you have a question that starts your thread, but exactly what do you want to know please?
It's hard to tell from your pictures what question you want answered. Perhaps if you give a little more detail of what's in your pictures someone could find an answer to your question.
Sorry to be so vague the pictures are supposed to show the soil I am digging in about fifty ft. Off of a old creek. The soil is a light golden color with veins of black some of which are soft and some have. Formed into a hard shiny looking stone like aubstance. I don't think it's coal there are also some veins that look almost like gold but upon close inspection the are actually white in color.
Take the dark stuff from the streaks and pan it down. Use a magnet to see if any of the black material jumps to a magnet. If it does, you've at least found super-heavies. Super-heavies, that's where gold likes to hide. (If it's coal, it won't be attracted to a magnet either.)
If none of the black material jumps to a magnet, you may be looking at rotting organic material (or coal). Plus, when you try to pan it, the material will be very light, and it will wash out of the pan very quickly.
What's the history of gold in your area? Is it micron/flour gold? Or, is it flakes and chunks?
Research will be a key, and perhaps you've already done a lot, if not, look up everything you can find in your area about gold accumulations and gold recovery.
If you're in Georgia, you should be able to find some material to help narrow your search as Georgia's gold history goes back quite a ways.
