- ALLUVIAL GOLD PROSPECTING - HOW TO CAPTURE SUPERFINE GOLD SUSPENDED IN SOLUTION
In this video I demonstrate a simple, but effective method to capture really fine gold that is literally suspended in water. Commonly called "Mustard Gold" or "Gold Dust", it is so fine that most conventional tools will struggle to capture it. Using a piece of metal tubing and some calico bags, a simple filter can be made to strain the water that is holding the gold. Although the amount caught is negligible in most cases, where large volumes of water are involved, this technique can be useful.

I've had great luck with synthetic cloth filters. Black curtain materials from craft stores are awesome.
Most are sorted by mesh/thickness so it really opens up options for different dust sizes. Cheers!
Great Demonstration!
Moved to Australia when I was 5. Lived in Adelaide till 12. Love anything Australian, so always enjoy watching folks Down Under with similar hobby as mine.
Now in Montana, and i prospect the Yellowstone River. LOTS of flour gold! Your video just added a new activity for me to try.
Great videos! Thank you.
That's awesome mate...please let me know how you go. Regards Aussie
Great video, John. Thank you for sharing
You're welcome mate. Regards John
Love you so much for your new discovery. God bless you🙏🙏🙏
I will definitely be trying that! Thanks!
I wish you luck. Regards Aussie
awsom work!
Love your videos mate! Good stuff 👍
Thanks mate..glad you like 'em. Regards Aussie
after watching this I went to my blue bowl and took the filter apart as I noticed it was slowing the water flow and paned it and I couldn't believe my eyes. your videos are outstanding. thank you
That is awesome. Thanks for your feedback mate. Regards Aussie
Thank you
thanks more great info
You're welcome mate. Regards Aussie
good catch!
Cheers Mate. Regards Aussie
Thank you for the idea, I would have not thought of that, where I live there's a lot of flour gold, good video.
You're welcome mate. Give a go.. good luck. Regards Aussie
Omg I have gotten it down that far for years and I cannot seem to get it out the pan!!!! I have left it sitting until i can get an idea that collects it all from the pan!
I hate leaving bits behind even the stuff ppl don't belive in haha
Love you so much❤❤❤. God bless you brother
I helped teach the visitors at the Las Vegas GPPA show two years ago, they use about 20 ft of panning tubs. The gold that they put in was from the beaches in Alaska. Super fine! 3 hrs in my arms were coated with glitter and then 1/2 dollar size floaters started showing up in the tubs.
It was amazing to see! Somebody found some jet dry and back to busyness.
I have know idea how someone caught that dust in the 1st place. But! I'm working on it! Lol
Awesome video, till you see it you won't believe it!
Thanks mate. Yes, it's hard to believe that superfine gold can come together like that and float. Regards Aussie
👍👍👍 well done my friend , nice video 👍👍👍
Thanks mate. Glad you like it. Regards Aussie
Hi John..
Thanks for sharing your knowledge on how to recover that super fine gold.
Cheers Tony.👍🍺⛏
Cheers Tony. Regards John

You are welcome mate.👍
I have played a lot with fines trying every different way. Right now I have a medium sized strainer with a handle. In it I have a piece of silk I cut to fit my drained and I have the drainer propped over a small trash can. I had an amazing hike and have been crushing and rinsing
I shared your video I love it. People have been telling my family I'm crazy. But they say a lot of the gold is so micro fine you cant see it with the naked eye
Glad you like it. Regards Aussie
good stuff mate love your work great vid on finding the lead or ribbon in a dry creek bed .
Thanks mate, glad to help out. Regards Aussie
👍 awesome man.
God this is depressing, To think I have thrown out 1000s of buckets of water over the years thinking I've caught all the gold and I have been throwing some of it out. I will be trying out this method from here on. Thanks for sharing. 👍
Very cool..I'll try it
Have fun. Regards Aussie
Hi John, great demo on very fine gold recovery. You just gave me a great idea for my spiral wheel recirculating system when working with very dirty water. Steve
Thanks Steve, glad to help out. Let me know how it goes. I'd be interested. Regards John
Hi John, well I have set up an overflow from the spiral wheel self contained container going into another bucket. I needed to do this because I am running crushed red clay and I was only able to run the wheel for about 15 minutes before the sludge would clog up the stocking type filter. I have used another material that is not as fine as the stocking stretched over the top of the bucket where the overflow goes and the pump is in the bottom of that bucket. I am now able to run the wheel for about 5 buckets of crushed clay @ 25 mesh before I need to do a full clean up. (about 4 hours running)Anyway, long story short I have rinsed out the filter and let it sit overnight. I am amazed on just how much fine gold was suspended in the water. So yes it all worked but the wheel is dialled in very well and picking very very small flower gold in the cup. I will put up a couple of crude vids on my channel later
That's great to hear it worked. Good on ya mate. Regards Aussie
Thanks John, I have just made a quick crusher for that hard clay lumps so I can classify down to 20mesh before running it through the wheel. I will post up a crud vid of it later on my channel
Great video mate ⚒
Cheers Tas. Regards Aussie
Nice demonstration. When the gold fields dry up then only those that can do this will be finding any gold. I think this could become a successful way to mine after developing equipment for doing this on a larger scale. 👍👍
Thanks for the thumbs up, but I do believe that Hell will freeze over before the Gold Fields dry up. Regards Aussie
Thanks for teaching me not to worry about such a tiny amount of gold, unless you are running continuously so it can accumulate into a reasonable amount. At my current hobbyist rate of processing it is not going to make any difference until a few years of filter collection.
Yeah although gold prices may skyrocket over the next few years too so never know, maybe it will be worth it. ))
Always remember, ever little bit adds up.
I saw a video on this topic before.....the guy cut a hole on the bottom of a 5 gal bucket and put a 2 inch shipping tube cover in the hole. He then stirred up his dirt and poured off the water with the fine silt only. Then he added a chemical from a waste treatment facility to drop the heavies. From that point he stirred the water and the gold settled in the tube cover. It was amazing what he caught. I have a 250x scope that hooks up to my tv and the amt of microscopic gold blows my mind (on the tv they're 2 inch nuggets and I can't see them in a 10x loop). I'm going to try your chemical free method as I've saved most of the silt from the pour offs just for this reason.
Thanks or sharing... I'll give that a go. All the best mate... hope it works or you. Regards Aussie
Now that was cool
Cheers mate. Regards Aussie
Thank you, gold is gold to me even if it's dust, I can not understand people who leave dust behind, if you collect as much as you can and melt it down you end up with a nugget. G'day mate new subscriber here from Sydney.
Yes, it all adds up. Cheers. Regards Aussie
Thats a great demonstration of how fine gold gets caught up in sediment which is what you were filtering. Try explaining this to people who think putting a pan at the end of a sluice shows losses. You can also double pan your sedement into another pan and top it up with fresh water and use the tap method to get a show. Im sure youve opened some people's eyes here as to just how fine gold is
Cheers mate. Yep agreed... double panning is a method I use often. It is truly amazing just how fine Gold can be... a great challenge to process. Regards Aussie
absolutely its something we are working on everyday
Interesting video. I was thinking about this and perhaps a filtering solution/system to capture this stuff without the labor involved. Perhaps a number of fish tanks in a row to further separate it out on it's own just through recycling the water. Nice job.
Sounds interesting, Regards Aussie
If one collected that from multiple workings, adding that to a refining process used to get gold out of circuit board fingers seems to be another way to harvest all that fine stuff
I get what you are saying... but way too complicated... simple is best. Regards Aussie
Ya I know I’ve got some material right now that I’m working that has super fines in it. I can see it just rolling with the black sand. I panned one little scoop and ran and got my phone and ordered another bag. Found more gold in one scoop than most other brands. It was a 4 lbs bag and was priced the same as some one pounders. So I wasn’t expecting it to be so rich. No nuggets after classifying but a lot of flakes and fines. Just gotta get those fines out somehow
Gotta be keen for that much
Some people are that keen.... having said that, the amount was NOT the focus here. The METHOD employed to catch such fine gold was the point here. Regards Aussie
Yes, very interesting indeed , it certainly can be extremely fine, once you have it like that , then the next step is put it in solution ,and drop it out with SMB , or Mercury , for the environmentally friendly neither of the aforementioned processes lol if you know what I mean ,good info.
Yep there are other ways, but this is easy, very inexpensive and SAFE. Regards Aussie
Aqua regia and hydrochloric , or zinc and charcoal😉
I get lots of that showing in the very bottom of bucket or tubs. It’s always the last thing that remains. I tell people I’m sure it’s gold they tell me it’s clay. Clay though would pour off early right? My district is well known for micro gold so fine you can’t see it in some veins. I really like this solution you’ve come up with. 1/4 tsp per bucket would add up quickly.
Theoretically, yes, with thorough agitation and mixing clay should pour off. Thanks for the feedback, Regards Aussie
Some people just can't listen to reason. I told a buddy of mine that it would NOT still be in the pan if it was clay and he just doesn't want to hear it lol , guess he's got his sights set on the big pieces.
Find the clay!! It does a fine job of trapping the dust. I filled a 2 gallon pail and it weighed as much as a 5 gallon bucket of paint.
I have recently found alluvial gold in Canada . And did this same process to extract my gold this is the first video that do it the same way I boiled the water to extra the dust in a pot then scrap the dust out and refilter I must have had to boil down 200 liter of water to extra 2 troy ounces . I am still trying to find a refiner or grader I messaged a SGS but no reply . The gold came from paydirt for a house foundation I have no mining lease for reclamation.. I am not sure if that is a issue as I just found the alluvial gold and like you see in your video all the gold particles show in water very noticeable I washed it off with a garden hose and nothing but gold particles everywhere .. I was like it's running off the table I got to put this all in water from then catch it and boil out the different elements very one thinks I am crazy because I haven't got tested yet and we don't know if it's gold .. I feel like jack sparrow with it lmao I got a hat or dirt ....
My mom is in humbolt , ca she gets these mesh bags called bubble bags for making hashhhhhh🤫. Would they work ?
Hi John I live in Edmonton, Alberta, Western Canada and this region is pretty much all flour gold so I think your method is going to a standard procedure
Good luck with it mate. Regards Aussie
I live in yeg too. See you on the nsr sometime.
👍👍👍
Hey John, is it always you get that fine gold dust at tge end of processing?
Good question. I crush a lot of specimens, which always produce very fine gold from the crushing process. So no, I wouldn't expect such fine gold from sluicing for example. Regards Aussie
Another way is to try something like this (thanks to Goldrushgang for leading me on to it);
Get a 9 litre plastic bucket and drill a 20cent size hole in the middle. Stick a square of black duct over that hole from underneath and half fill the bucket with your water containing suspended fine gold. Swirl it up really well and then let the water settle. Tip the water out into another bucket and peel off the duct tape. All your fine gold will be driven down and inwards to the duct tape, even floating gold will be driven under, where it will stick to the glue on the tape covering the hole. This is good for fine gold final recovery or for loaming for fine gold - no good for bigger gold. Wipe the gold off the duct tape with a tissue soaked in kero or petrol, whatever, as long as it dissolves the glue. Then burn the dry tissue to recover your gold. Try it with fine copper filings and you'll see what I mean. I'd include some pictures but can't seem to get them into this comment. Cheers.
Sounds really interesting..I'll give it a try. Thanks for the input. Regards Aussie
I saw a guys video on something like this, but he drilled a hole in the center of the bucket the same size as a small cup, (maybe a jar lid?) and would just put his heavies in and, get it spinning fast, let it sit and put a cover on the cup, then carefully remove the cup, large and small gold and some black sand. He was sold on it.
What the ef is a 20 cent sized hole? You talking centimeters ? Or is there some oddball 20 cent piece floating around that i don't t know about?
@@smoochmagooch7559probably an Australian 20 cent coin which appears to be about 2.8 centimeters or approx 1-1/8".
Is they canvas bags?
What is a Calico bag please. I have only seen those kind of bags in Australia, which were used to transport the awesome leather hats unique to Australia. Thanks mate.
Calico is like a cotton type of material. Jump onto Alibaba and you will see there are heaps of companies selling them. Regards Aussie
@@AussieBlokeProspector Thanks. I believe I found them. Cheers mate. What size is your concrete mixer motor please thanks. It is hard to see the specs on the video but I know it's 220 volts. Not sure of the amps and watts.
It all counts
My gold is so fine it washes even after you bag step the re-pan. What other way can I capture the gold from the water
They been doing a lot using silicone mats to catch gold. Wonder how well it might cause suspended gold to attach to the walls if ur pan were lined with the silicone rubber.
If it's suspended, then it may not touch the sides. Regards Aussie
Why not just boil off water? Much thanks enjoy your site and videos!!!!!!
You could...would take a while though. Regards Aussie
How would a couple of Coffee drip filters go, let them dry and then burn them off
I reckon Coffee filters would work well, although if you are talking large volumes of solution, you have to come up with a slow way to fill them. Regards Aussie
Thank you. If we can figure out how to get the fines, we will get the larger pieces by default. There is much more fine gold as opposed to bigger pieces. I want to stay away from mercury.
Spot on.... Regards Aussie
What bags?
Another problem I found is in order to do anything with this you have to be able to stay somewhere like out in the middle of nowhere for long periods of time. If you are working a 9 to 5 job that makes it impossible unless you do it Saturday or Sunday. This is why it takes so long to get anything. You could have someone grubstake you. Or bring you food and supplies. I did that. The guy who was grubstaking me never showed up to bring me food and I almost wound up starving to death. He forgot about me. We were supposed to split the profit 50 50. I wound up eating mushrooms in order to survive. These things really stoned me out. I finally said f*ck this shit. When I got back to civilization I found this guy in his apartment as drunk as a skunk. WhenI reminded him that he was supposed to bring me supplies he said oh I forgot. Well that was the end of that. What little gold I did get when I sold it, it wasn't even enough to pay for the gas up to the mountains. I was so disgusted I put everything on the back burner until I could find someone I could trust.
I went up to my spot every Saturday this season. Mostly just me and my dog. 2 mile hike from the truck.2 hours from my house. It was tough. I took a 10 day break from work. I went every other day. Was tough. Season ended 2 weeks ago. It was worth it just to tell the story. Elk. Bear. Wolves. It was lonely, but it felt good afterwards. Get your shit, go where the I'll timers went, and find some gold m8. (:p
what is the bag/material you are using? and the superfine gold does not pass through the material correct?
Calico, and yes it catches the fine gold. Regards Aussie
@@AussieBlokeProspector good thing to know, thanks.
@@AussieBlokeProspector Calico comes in different mesh sizes, what specific mesh are you using?
Great question.. I can't say the size, but I just get the top grade stuff, with the tightest weave. Regards Aussie
@@AussieBlokeProspector ok thanks a lot for the help.
I tired that once with coffee filters worked pretty good a little tedious to do it that way.
Great Idea. Regards Aussie
Hi mate we’re did you get those bags cheers
A quick ebay search will get you sorted mate.... or if you know someone who is handy with a sowing machine, you can buy calico at most haberdashery shops. Regards Aussie
What about evaporating the water away to leave the gold behind?
It'd take 2 months for the water in that white bowl to vap off. Maybe if you used a hot plate🤷
There are 40,000 gold dust particles in an ounce. It's tough to justify all the materials and time it takes trying to capture enough to make it profitable. Where I am in Nevada (US), there is a considerable amount of clay (very fine rock dust) that gold dust has an affinity for, even with detergent. It's not just surface tension or electrostatic pull that attracts the two to each other. So, I need a chemist or electrician who thinks outside the box to come up with an alternative to mercury or cyanide. It needs to be cheap, readily available, quick, safe to handle, environmentally friendly and not require considerable heat or pressure. A warm and mildly acidic solution of thiourea and fat is my latest unsuccessful attempt but may be a step in the right direction. We'll see.
You can look into ' growing gold' a chemist does this after taking gold from electronics
Gold will float even if it isn't microscopic like that gold does not get suspended in water either that's why we use soap (dawn) reduce the surface tension and don't float
What about a centrifuge?
Hi Aussie Bloke Prospector I would like to know why you are looking for gold dust, I know very well that there are tons of gold in that country?
And I would like to know why you would ask ask such a question, when clearly this video is simply demonstrating a method of recovering fine gold that is in water, NOT about searching for gold dust. Also, if you know so well that there are tons of Gold in this country...then get your arse over here, and make a video and show us all your expertise. Regards Aussie
It all counts no matter what size.
Yep.. it all adds up.
I will use coffee filter..early morning I brew my coffee and my gold on the other hand...
Great Idea...and a great combo..Coffee and Gold... 2 of my favourite things. Regards Aussie
I have been out there, done just about everything to trap gold. Developed unique technologies to trap that fine gold. I came up with interesting ideas. But if you want to make a living at it you need to developers a fast way to trap it. Just collect it and melt it down.
I have done this before. It's a very slow and tedious process. Takes forever just to get anything. I think it took a month just to get a gram. It's good info though. I eventually had to use mercury to pick it up. If you do it this way you really need to be patient
Yep...this is really only for those out there who can't bear to lose ANY gold. Regards Aussie
He only left me 2 weeks worth of food and in two weeks I only obtained something like 10 USD in gold. I'm sure It was more but the buyer only gave me ten for it. I felt like I got ripped but there is always another day. That was 20 years ago. It's not easy.
If you’re not on a time frame can you just let the sun evaporate it ???
I reckon if you could spread out some plastic sheets with raised sides, evaporation would be an excellent method. Just gotta make sure the wind can't get at it. Regards Aussie
could you use mercury
Of course , but that's not the topic here.
I have also heard that 40 percent of the gold is so fine it washes out of your gold pan or sluice box. What I really hate is going into a place two days after someone dredges the area with a big dredge. You can't find anything. They either got the gold and or the super fine gold washed down the river. So you have to keep looking until you could find a good spot.
Why? Why add more water. Once you rinsed the cloth you should of boiled it down...
I like the idea, but putting the sludge that was filtered back into water seems counterproductive.
I wonder if a solution that has a lower density than water would work better for final panning/seperation. Perhaps an alcohol solution with low surface tension would sink more of the extra fines.
I agree with you. This was done purely to show the results. Amounts that small and fine, once caught, are better treated with mercury. Regards Aussie
I think the bag should go directly into the furnace once Sun dry
avoid the temptation to use your fingers in the pan. the oils on your skin float the gold. a tiny amount of oil will float alot of gold away. otherwise great tips
The buyers excuse for giving me ten dollars for I think it was around a gram of gold was that it wasn't marked for a gold value like 14 K etc. He had no way to test it so he was taking a chance on buying it. If you want to get it marked for Karet value you have to spend 50 dollars to have it assayed probably losing most of your profit. He told me nobody else is going to even look at it. Ten dollars take it or leave it. So I had to take the crummy deal.
Better to keep it
I think you dont not the shaker table mate
I think that you don't make sense mate... oh and BTW, don't bomb other people's channels with your links...it's just plain rude
USE jet dry/ dishwashing liquid breaks surface tension the gold will not float anymore
Incorrect... firstly, although breaking the surface tension with detergent will cause the majority of gold to sink, not ALL of it will and that's because we are not talking about floating gold here, we are talking about Suspended gold.
Hash bags people hash bags
I wonder how much gold I have thrown away… 🤦♂️🤯
The method of recovery is amazing.
Just fyi, the editing made me dizzy. you poured full buckets and empty buckets and back to full again. So many edit cuts and different angles it made me dizzy. Take care :)
Cheers mate. Sorry to make you so dizzy. Regards Aussie
I have 50+ pound buckets of paydirt that is LOADED with fine pure gold. Do you know of anyone that would like to purchase? I am willing to send out samples of what I have at no cost, receiver only pays shipping.
Where are you located?
