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?

Found it!
For concentrate cleanup only so you'll need a screen to classify your material down to #30 mesh or smaller, that's all it can handle.... and it needs to be run sloooowww. Something to do while you're watching TV or something. Fun indoors job and maybe the hubby will take an interest once you get this thing running, cleanup is pretty fun when you're getting some color. It's nothing crazy-nice but it definitely works very well when set up and run correctly, not difficult. I used it for a while but am now a Blue Bowler for the #30 and smaller.



These riffles are killer, hard to imagine anything making it through that gauntlet. Similar to GoldHog matting but Keene


This is looking up at the top section where the water feeds into the run. It disperses in that PVC "T" then comes out through that green scrubbie material and is supposed to evenly feed water across the green slate (slate paint) section. That scrubbie piece gets cloggy every now and then but you can stick your fingers in there to adjust or clean it somewhat when it starts acting weird. Could probably pull it out and stick a different scrubbie in there too if you wanted to experiment. Most Gold that I've recovered with this sluice has been in the upper green slate-painted flat section. It rarely makes it to the rubber riffles and I've never found a speck of gold as low as the carpet section. The carpet section is the only piece that is removable.


And this is where you screw your feed hose in, it has adjustable flow.
