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?

You're gonna make me cry (in a good way). I understand where you come from and I give freely as well. I just have been taught to earn my keep. I accept your proposal gracefully and will message you when I fulfill my end of the bargain. Thank you so much swizz. It means the world! I'll do my best to follow suit and share my knowledge with others and be the best non-member representative!
