A friend sent me a photo of what he says is alluvial gold he has found in ancient riverbeds in Colorado over the years. Can anyone verify if he is correct and this is truly "alluvial gold."
Thanks very much!

Why not just phone around and find a pawn shop or a non-ferrous recycling company that has a XRF tester.
Then you can post the results up.
There seems to be one common element of all these type posts.
Nobody has had the testing done.
Really why is that?
If I thought for a minute I had something as you state, well the test would be first on the to do list.

Before you do that, take a small piece and see if it crushes. If it is solid gold it will not crush. If it crushes, crush it again as fine as you can, and the pan it to see if any stays in the bottom of the pan. It will save you some time and money.

My experience, not here but in a jewelry store in the mountains in Colorado, say, if you have to ask, you don't have gold.
Sorry.
Some people need more convincing. Some people just know they have found a fortune. I found a great treasure. My kids and grandkids.

By simmering I mean I brought them to an almost boil in water. I have an electric kiln and am waiting for a new piece that goes inside and heats the gold and I am going to mortar & pestle a few grams, add a little borax, then heat the gold up to melting point and pour into a square ingot crucible. Seems like an okay idea right?
Not sure what a boil in water does for you. Melting point of gold in over 1900F

Thanks for posting.

Looks like siltstone with flakes of mica to me. I may be wrong on that but most certainly not gold. If you look closely you can see cracks in some of the stones. And as flinthunter pointed out, no weathering from a stream bed is apparent. Well maybe a slight amount but not what would be expected.
Specific gravity?

I am confused. Your original post said a friend sent you pictures of alluvial gold he had found and you wanted help from us with identification. But as your thread goes along you reference what you are doing with the alleged gold and even reference finding more. So what is story with that?

Granted,I know little about this subject so I too am confused a bit. At first we were talking alluvial gold,which I at least have an idea about and now we,re talking rocks,found by eye with platinum and palladium. Please enlighten this old country boy so I can at least follow the discussion. Would be much appreciated since I find this interesting.
It is starting to appear to be a riddle, wrapped in a mystery, inside an enigma.

I crush that gold and it test around 22kt. Grant you guys think I'm an idiot, but that isn't the case
#1-What did you crush?
#2-The pictures that you posted up in #79 shows a lot of different rocks, so which one, or all of them?

#3-Just trying to get a sense on what you are claiming to be 22kt. all of it or part of it?

#4-Did you crush the sample that the Bic lighter is sitting on?

#5-What was the weight pre/post of crushing and what was the recovery?

Sorry to burden you with the 5 questions

I find all of this quite amazing that such a rich source of gold can be obtained so readily as you claim.

I Soaked them all in Sulphuric Acid for 6 days and they didn't lose any color, I also boiled them and they conglomerated together in a soft malleable solid piece. I have also taken a few flakes, added some borax, and hit it with some map gas in a crucible. Gold was definitely seen under a microscope after I had created a "button" to the naked eye it looked more silver, but there was noticeable gold in the after product. Plus, I have used sulphuric acid many times and it eats away just about everything other than high grade gold ores. These all seem promising to me?

Any feedback is greatly appreciated.
You took the photo your friend in Colorado sent you, then soaked it in acid? I’m confused. I don’t see any gold in the pictures (this time either). Good luck.

I'm iffy on this. If this yellow material came out of an ancient riverbed it should be rounded and worn smooth. Everything has sharp edges and corners. That doesn't mean there is not gold in it, it just means that in my opinion, what we are seeing is not pure gold.

I've lived in CO all my life and spent a good amount of time looking for gold and I don't see any gold in the pics. Like others have said, take a piece and pummel it into dust and pan it. He clearly has three gold pans to put to use. It will all wash away except the heavy's which will include black sand. The gold will shine like no tomorrow in the black sand and against the green pan. Pyrite will kind of look like gold but when you shade it, it no longer shines. Plus, it will more than likely wash away with the light material, and, it flakes apart. Gold will shine in the sun or shaded with your hand. It's unmistakable once you know.

It is actually because Colorado, one of the main and diverse mining states in the country has very limited businesses involved in the gold ore community. Everyone thinks of Colorado because of the finds of gold and telluride in Cripple Creek, but many areas have been neglected because the majority of mining company's went bankrupt back in the day. I have difficulty even discussing the topic of prospecting and mining with anyone in my valley (near Aspen/Leadville) it seems the the only people interested are west in Navada and Utah.
Cool then,keep on keeping on panning that gold!
