more soil questions, noob strikes again! Options

So I've been digging at this river for a few days and I've noticed some interesting soil deposits. I'm wondering if they are even worth my time. In one area there is an eroding man made rock slide area that backs to a willow covered plain. I went digging into it today and found a decomposing vegitation/mud/black sand layer underneath there I found a rusty sandy lome layer. It seems to be untouched by others judging by the red stained rocks I went through.
There is another section I played in across the river where there is a dark black sand area that has black stained rocks with silver streaks running through the stones. Above the dark sand area is a normal river sand layer.
Do either of these sound like it's better to dig through? Or if I need to provide more information?

I feel a little cheesy for saying this, but the people are what make the organization what it is. Isn't that the mission statement? I never expected anyone to step up the way Chris has, it's amazing and unprecedented. From a newcomer's outlook, the group of people here are of the highest caliber. I cannot sing high enough of a praise for this organization and the people who drive it on. From Chris's insane kindness, Dennis taking me under his wing (in time we will get to CC!) Mr. and Mrs. P with their talent and kindness, to Caveman with his wisdom and overall good spirit. It is simply amazing! You folks have set the bar high! I will forever strive to contribute to this cause because I believe in what I've seen. (Now if I can only pony up the dough!)
