Gold in Sand and Gravel pits

[GoldReport]

Hi everyone!

Novice prospector here. I work for an aggregates mining company and have talked with the company geologist about gold in our s&g deposits. At my last site visits in Southern NY + NW PA I took my gold pan. I grabbed about a gallon of material from the sand screws and panned them. I would have done more material but was time limited. I did indeed find some glacial gold, really small stuff. What I am having a tough time figuring out is what processing this would look like. In my head I would set up a sluice box where the chute that feeds the sand screw is located. It would need to be something as low cost as possible and would not need to be cleaned out very often. Anyone have any pics of their setup they would be willing to share?

Still trying to determine the concentration in these deposits. If they could recover at least 0.01g per ton of sand, I think it could be profitable as an additional revenue stream.

Do you know what their setup looks like? Curious what people use... is it just a couple of parallel sluice boxes in between the wash screen and sand plant?

I was meaning to run my material last night but my pump decided it wanted to die. What I get for buying a 15 dollar bilge on Amazon. The main reason for using my homemade sluice at all is just to test out its functionality. I'll definitely save all the material and pan out material one bucket at a time if I don't feel like the sluice is catching all the cons.

No one gets to see it I heard about it from an ex worker who runs a concrete plant now. I am sure they just run it all down some sluices. That is what everyone upstream does. High bankers.

Fine could be good though in a large source like a gravel pit.
Probably not so good for a recreational miner but sometimes is ok for a commercial venture.

They actually named a cove in the lake, fine gold cove I think it is directly across from the old submerged fine gold, gold mine and just up the road is the town of Coarsegold so that tells you what kind of gold you get up there. LOL On the river I always just get fine no matter which spots I go to. But gold is gold just need to keep your eyes open for rattlesnakes I almost stepped on a coiled 6 footer while not paying attention luckily his head was under the rock and he didn't sense me.

Years back the GPAA had a video for sale of "Ralph " talking about his finds and there was a sand & gravel plant in the back ground of the show and it was "'apparent " and hinted that this was where he had gone to get his material from. I have that video somewhere . that video was my hint to do just what Ralph was showing . It's just sitting there waiting on us !

It's there, but so is ALOT of black sand,

I ran a bucket of concrete sand I got from my local place here in Jersey. Found a bunch! of black sand but no visible gold yet. At least was a good test on my homemade (kinda shoddy) recirculating sluice. The 1100 gph pump I bought wasn't working for some reason so I hooked up my 600gph pump. I measured how long to fill a 5 gallon bucket and came up with 350 gph of actual flow. Is this normal? Maybe I need to rethink my setup a bit.


In any case I'm not surprised I found a lot of black sand, Jersey was once a major iron source for the US back in the 1800s and I live in the heart of that industry.

Loaded to the gills with black sand maybe I should empty out more regularly? Or need a new setup altogether

Actual GPH pumped will vary depending on how high the water is pumped. The rating may be based on a lesser lift than you set up for your test.
