UnderFlow Sluice Box Gold Mining Equipment vs. Drop Riffel There's A new Sluice In Town

[@LEARNTOPLAYCRAPS]

Customer testimonial.......I own one of these sluice boxes and can say it is the finest piece of mining equipment on the market today. Grumpyprospector is going to take the mining industry to a new level with clean Gold collection.......no mercury or acids needed to collect all the fine gold with no black sands or panning at the end of your run. By far and above the easiest sluice I've ever used.

[@StevenHanover]

11 years ago how do we get one in 2024

[@XGrumpyProspector]

The level of customer service I received was outstanding!! Thank you for listening to me talk about finding gold in Louisiana and not thinking I was crazy,please see the attached picture. As I told you it is super fine and impossible to separate by panning.The dust shown in the the vial is from running for 2 hours(about 1 gallon of cons.)with my new Underflow Mini. Turns out I did prove that there is gold in central Louisiana! You just have to look in the right place.

[@XGrumpyProspector]

Thanks for your comments. The UnderFlow is truly a game changer in precious metals mining. Yes, it works on gem stones, too. Each UnderFlow sluice is built by hand to our strict specifications so they last. It may be the last piece of mining equipment you ever have to buy......until you need a larger one like you said. We are excited to offer the best piece of mining equipment available to the public. Thanks for your business and your time. Good luck with your prospecting!!!!

[@GamingKeenBeaner]

This is very clever. I think having a perfectly smooth bed to the riffle holds the idea back a little with the very ultra fine gold, but that would be easy to change. The design forces even the particles that float to go underwater. Its solid thinking.

[@peterpazzi8565]

I recently bought the mini underflow sluice box 2' x 5". I am using a 600 gph pump.. It says to use 325 gph.I will tell you even with that much flow going through the fine gold still stays in the trap. I'm telling you the truth.. I am very happy with my purchase and will be ordering a lot larger underflow..I am not skilled at using the underflow but I even have gold showing..XGrumpyProspector you have a great design.Thank you.From the goldprospector38..From Port Alberni British Columbia Canada..

[@XGrumpyProspector]

I will upload a video showing exactly what you have described very soon. We will be uploading new videos showing new models and designs of the UnderFlow Sluice in the very near future. We are changing the way people mine Gold around the world. Fine Gold capture has never been so easy. A skilled operator can easily capture the fine Gold flushed out by traditional sluice boxes. No need for rubber matting or miners moss or any consumable materials. No panning at the end of your run, either.

[@AmericanMediaRev]

The concept is good, have not seen it before. What I would like to see is concentrates going into it, as in over 50% black sand. Often you can get a handful of black sand in a single panning. Please dump in a pint of mostly black sand concentrates with gold being the same size grains or smaller. If you have lets say 2 grams of gold in a pint of black sand, pour it through, and get 98% of the gold in the trap with less than 10% black sand, I am sold.

[@darinharder2085]

I ordered a double trap system, I can't wait to try it, it sure looks amazing, all the other sluices I've looked at require tedeous cleanups and more panning afterwords too. This system looks like theres hardly any work afterwords, and you can see the results right away. I think you have a great product, I wish you good luck on your sales of your products, looks like you've thought this out, Thanks, Darin

[@fortnoxz71]

I have never seen any thing like this in my life!!! but then started thinking... This is the basic design of a waterfall.. So simple so basic.. and here it is !! Good job !! I have to make one of these !!

[@IMKINDOFABIGDEAL13]

not alot. i am in gresham and the only place i have found anything is traveling south. little north fork on the santiam in marion county will produce small amounts of gold or you can travel a little further south to quartzville creek near sweet home and albany and find some but i have not had any luck near protland. you should go to the prospecting store on division called dk nugget and talk to the guys there

[@XGrumpyProspector]

It is a System, with many sizes, attachments, and overall Gold collecting purposes. For the Miner to CHOOSE what setup will work best for what your Gold collecting needs are to be. Pricing goes from $100+ to custom built large commercial for thousands.

[@ALIENJUGGERNAUT]

How about setting up a trap after your sluice and panning it to see what made it through?

[@XGrumpyProspector]

I'll post another video demonstrating the drop in Gold. For instance, just because fine earthly dust exits, does not mean even the finest of Gold is. Dirt and Dust is far lighter than the Gold. I have extensively tested this prior to posting, & no reason to capture fine dirt that contains no Gold particulate? Right? Thanks for comment, I appreciate everyones comments and for paying such close attention to details, Thanks Grumpy Prospector

[@peterpazzi8565]

I bought the mini underflow sluice 2'x5".It's say to use a 325gph pump.I'm using a 600gph pump, even with that much water flow going through the sluice I have fine gold staying in the trap.It's all in the way you work the gates.The angle of the sluice box.I had material that I ran through the underflow and had very very fine gold showing and fine gold showing.I used a jewelers loop to see the very very fine gold.I wanted to put this design to the test.Well it passed for me with flying colours.

[@XGrumpyProspector]

Quote: " Life is like riding a bike. You can be given a tool! --- But it takes personal skill, talent, and understanding by the user, to have it perform as it is designed to do." One last thought: Make sure you have real Gold, if so, this system will capture it.

[@XGrumpyProspector]

Just search; Placer mining in Oregon, and You will find some good trails to follow. I tried L.A. and moved back almost immediatly. Nothing beats the Colorado Rockies in a small town. Plenty of sunshine too!

[@mws123]

i have been gold panning for 20 years. i started when i was 5 i am 25 now. i think i can handle a pan good enough to not loose any gold and do it quickly

[@tildens100]

This looks great, hows it handle black sands, I like the concept with inline classifier ,like a bazooka gold trap, springs coming how does one email you?

[@tommychook4552]

we in nz call that a boil box,,placed in front of the sluice box to hold back the bigger bits,,we dont get fines in it

[@BrokenRRT]

Tom Fowler - I believe "boil Box" is what my prospecting friends here in northern Arizona USA call it as well.

[@احمدالشيخ-ذ1ذ]

BrokenRRT

[@justkiddin1980]

Nice...but how does it deal with a constant flow of material?

[@jonjara1234]

yes, I too noticed tons of material escaping out the sides! Great Idea, just work out that issue of how to stop the small dirt from escaping.I ll keep following Jon

[@patriziosaintmartin]

Hey Mike, good to know you are coming to South America soon. Good luck.

[@pauldean8638]

The pics of a orrpiallage(prob mispelt) they have a split feed so would cause a vacuum on other side of the gate ,if added airator block well before the trap and used a separate feed behind the gate to cause a better vacuum ,what would happen ? Could you enlarge the trap to run more material through it ? Best ask ones who would test the idea thoroughly

[@elmerfox6872]

I dont know how many of them you will sell but if I was where I could go and find gold I would buy a couple, good Idea. Hope you have applied for a patent.

[@nlo114]

Good demonstration. Looking at the principle of operation, you could probably use a funnel feeding a domestic 2" P, S or Q trap to clean yours cons. (obviously with a safety pan)

[@XGrumpyProspector]

The gate is fully adjustable. You can move it up or down and also from side to side so you can focus the water pressure in the trap blowing out all unwanted black sand and debris. You can dial in the sluice box and get all the control you need to get nothing but clean Gold. It works just like you see on the videos. Be sure to check out all the different sizes and types of sluices we offer on our products page at grumpyprospector d 0T c 0m.

[@ColoradoPirateMiners]

Hello again, so how do I find this underflow sluice and how much? We found 70,100 and 100+ mesh gold in Idaho springs and we had more 100+ mesh gold great color. I guess my question is would this underflow push it out or would it recover it? Whats our chance of a meet up or maybe you could demo it at our first coloradopirateminers club meeting in september. Thanks for all these great videos Kris Meese.

[@easyeagle2]

That looks like a really fine idea/invention to me. Have you ever tested results by re-running the tailings?

[@try2bpositive1]

Looks really clever and seems to work fast. I want one too!

[@natenwhy]

Question: Can the gold be displaced if the flow of water going through the trap is to great or what I'm saying is could the helical flow of the water at a faster flowing rate cause the gold to come out of the trap. or is the flow controllable.

[@mariuspascu2285]

Cam you set one of this direct in the river????

[@abigaillindsey1688]

Are youall sure it works on beach sand because that's the main reason I'd like to have one. If its no good on beach sand I can't use it. Please help me with this one?

[@haroldchurch6361]

Why all the loud music I really enjoy your work and wold like to see where the gate is on the sluice box L assume it is at the top of the sluice but how is it attached to the box and would you need such a long box if the gold is in the first three riffles and was fronted with a magnet. Thanks for hearing me

[@XGrumpyProspector]

Hey, I will be in Ecuador & Chile from Early November to May to sell all over South America. If you would like one sooner, I shipped a 3 foot long highbanker style to Chile for around 100 US Dollar & it took about 11 days in shipping.

[@terrapinrocks]

A huge benefit you're neglecting to point out is that your breaking surface tension. Watch any of the gold cube videos for an explanation of how that works.

[@Johann1001000]

Hi! My name is Johann, I'm little older then 13, Im only 65. The small gold washing machine, can I buy the machine somewhere? or do you build the machine yourself? I like this washing machine very much. Please respond!

[@XGrumpyProspector]

Hi Johann, Thank you for your interest in the Underflow Technology. You can go to our website Grumpyprospector Dot com and click on the tab that says shop products to see the different sizes and designs we build. If you have additional questions your welcome to contact us via email or phone.

[@XGrumpyProspector]

Here I posted above, a comment from a Prospector (Frank) that had purchased the exact system & from the same production timeframe. Where he,(as many other buyers), have entirely different productive results? Why is this? Because the system truly works in the hands of adept individual. This video was filmed with a hand held Canon Camera, with no special magic going on. What you see is real live footage - of a system when opperated reasonably properly will produce the same results.

[@benjaminlately]

Not without keeping all of the black sand. Most gemstones have a specific gravity less than black sand, but you should be able to tune it to keep most metals. Google "gemselect Specific Gravity Chart" Probably quicker to look for ruby with a UV light anyway.

[@xMrJanuaryx]

A good old fashion drop riffle is fine. The real test is re-running dirt. If you can do that without finding more gold then you don't need a better sluice.

[@goldensnova1374]

What is the width, height, depth, length ? thanks from Turkey

[@MrDetectorista]

hi i am interested in building one of those, I'd have the measurements? because I think the shipping to Argentina I would come out a little expensive or you could give me a quote with shipping included?

[@FlashInYourPan]

Oregon has many good areas to prospect, SW OR is very well known for it's gold mining and eastern Oregon also has a very rich gold mining history. Good luck

[@djpitr]

Very nice job , is this for creek or just for home clean up ?

[@jwhittaker5687]

have you tried this on big sluices /100/200/ or 300 hundred ton machines yet?

[@StevenHanover]

Are these type of units for sale anywhere online

[@DarkenedJay]

So what kind of prices will i be looking at if i choose to purchase one of your underflow sluices?

[@RobbyMarin-ds1mm]

How can I buy one like that u sell them I need one asap

[@XGrumpyProspector]

One way to find out is to try, I recently found fine Gold in a area I wouldnt have thought.

[@tmru2b]

2 questions...are they available yet? and pricing? I am very interested in a smaller one for processing classified cons primarily 1/4 and under at home. I am hoping for one asap as we are moving June 1 and I have limited time left in the Mtns! Any chance?

[@anagramconfirmed1717]

I super dig this. Do you sell these?

[@666hobart]

I found another video you uploaded the same day as this and they are clearly two different designs the david and goliath vid must be older the pipe you used is clearly larger, how did you go about determining the correct depth and does the flow affect it?

[@vusaljafarov3996]

Hi how can i order this equipment? thank you

[@savagepatty]

I would suggest making a 2nd layer insert with this system so that when the material is gone it’s quick and easy to lift the insert, slide the side and remove the gold, than you are ready to go again in no time

[@andylincks]

how u make it. can u send me a diagram or something on how u built it

[@milkymalkum5708]

Hi, My name is malcolm and im 13 years old. I always wanted to be either a miner/prospecter when im adult. Im planning the future and want to ask you some questions: 1. How much is a prospecting permit and how old do i have to be to get one? 2. How much money can you get from the amount of gold shown in that sluice? 3. Did you fast-forward the video or did it actually produce that much gold in 4:00 ? Please respond!

[@XGrumpyProspector]

Hi Malcom. Thanks for taking time to write us with your great questions. Prospecting permits vary from place to place. In Vermont, you need to fill out a form with the state and pay 25.00 for sluice boxes and there is no charge for panning with a shovel and Gold pan. In Utah, there are no permit requirements. Everywhere you should be sure you have permission from property owners to prospect. BLM land requires no permission but there are areas that are closed to prospecting like near National Park boundaries. The gold in this video is about 28.3 grams or just over an ounce of Gold. As of the date of this video, Gold is worth about 1300.00 an ounce, so there is about $1300.00 there. This video is shown in real time so no fast forwarding or any camera tricks. Our sluice box works just like the videos show. Be sure to check out all of our other videos on our fine sluice boxes from grumpyprospector d 0t com. Thanks again and good luck with your prospecting...!!

[@milkymalkum5708]

Thank you so much, i live in ontario and my dad says that if it isnt in my moms jewlery box, its not gold. But i swear i found some before! I have a ditch near my school that constantly fills with water and there are some riffle points and eddies that form, ive found a bit of gold-coloured material there. My dad says that all the gold was wiped dry since the last gold rush...but i think thats not true. Once again, thank you so much for awnsering me. Oh, and one more question: where can i buy one of the sluices you were using?

[@milkymalkum5708]

Also, i subscribed

[@XGrumpyProspector]

Malcolm McGlashan Hey Malcolm. You can get one of our sluices at Grumpyprospector d 0T com. We make several different units that are used for different types of prospecting and mining. Most of the easily to get good Gold was already picked up from the streams by the old timers. They were good and very thorough in their task. However, they didn't get it all. There are also some good spots up north in Canada and Alaska there where the glaciers are receding and exposing new ground that has never been prospected before. I've heard recent stories of guys going up there and filling coffee cans with nuggets in a single afternoon. Just have to know where to look. The stuff you are seeing near your school is most likely mica or fools gold. You can get a Gold pan very inexpensively and try to pan some out. Gold is very heavy and can easily be captured in a Gold pan after some practice. You generally need to dig deep to get the Gold, not on the surface in most cases. Good Luck to YOU!!!!

[@milkymalkum5708]

Thanks

[@hyepwr23]

does rubys and other gemstones stay with the gold also ?

[@turtlereacts2988]

Where might one go to order this system set up ?

[@nobullshiit5682]

Im surprised they dont make more of these , it works like magic . great job, keep rockn brother

[@bottle17528]

how is it with unclassified material?

[@sigerrnagai9622]

Would it be possible to add an airhose to it to help lift some of the material.. at a gentle rate just enough to tease some of the shit out

[@sigerrnagai9622]

Bubbler effect.

[@OG96932]

you bet me to that idea,, thinking of this a while back ago.

[@XGrumpyProspector]

I am working out Pricing for the Various sections of the Sluice system, Because it is designed for the miner, I have incorperated several choices so that you can customize a system to match your Gold collecting needs. Give me and idea of the type of material and Gold you feel you are to collect, and I will get you a reasonable pre production price quote. Thanks for your interest

[@robs9574]

Chevelle Rocks! great tune at the end. So do your production models have a view window?

[@XGrumpyProspector]

Yes all our products have the side windows to allow full visual control. Feel free to call or email us if you have additional questions!

[@silvesterweber2879]

I would like to order 5" model contact me [e-mail]

[@CahyadiYunus]

Good , i have a lot of gold and location fit with the workings this equipment ,our visit to Indonesia where,thanks

[@brianrussell4717]

Great idea but unfortunately not pratical out in the wild. This would be more for a clean up station. In the wild, you would have to wait for that to clear, otherwise it looks like it would build up too quickly and never make it under then creating a dam.

[@blancolirio]

Good demo, also really illustrates how gold naturally settles in the river.

[@mws123]

both may help but that looked to contain about 10 grams of gold. It took about 3:45 seconds to refine it. With a gold pan you can do that in easily 30 seconds.

[@GamingKeenBeaner]

The point in sluices is not that each riffle works faster than a guy panning. It is that the sluice does the panning work for you while also having lots of riffles for catchment. There are a lot of factors, but sluices are about larger volume and this demonstration is just one simple riffle.

[@XGrumpyProspector]

We set up a 5 gallon bucket off the end of the sluice and pan through the material to see if any made it through. If you see fine flour, re classify and re run your material at a lower water pressure. You can get near 100% recovery. -350 mesh is easy......-500 mesh and smaller requires a bit of knowledge and patience. You can get it all if you have the time. Our sluice is superior to any other design out there.

[@phillipag66]

do you have to keep moving the slate downward or is it at a set spot on the sluice

[@dwaynelowery5808]

For cleanup not production?

[@KD0CAC]

looks interesting , but missing a lot . 1st when was the last time my concentrates were void of any black sands - never . 2nd less of an issue , because this looks , but using microscope to look for any gold that may have made it through the system .

[@MrOstin321]

Does it also work with a dime next to sluice?

[@jwhittaker5687]

would this work on a 300 ton per hour trommel?

[@bobby7160794]

hello GrumpyP, i like what i see on the underflow system it shows me clearly that i want a system like this how did you make the flow so evenly or at a speed where it worked perfectly well non the less i mostly like to see it in action to watch how it separates right before your eyes im sure it does the same with flower gold , well and easy 3 words ? I WANT IT LOL how can i get a see thru sluice to do my concentrates do you have or do i need to build one you can reach me here or at my email

[@XGrumpyProspector]

Timelaps? The cut in filming was due to the fact I filmed this with a hand held Cannon camera. In which did not do well on batteries life when filming in video mode. Also just a couple lengthy minutes of video could max out a SD card. Unfortunatly these two facts caused me at times to add new batteries or sd card while filming. Bummer, they were uncontroled stops in filming. Nothing more than a quick change of battery or card and I resumed the video. In live action.

[@XGrumpyProspector]

$20 was what the guy commenting posted below. The metal I use is more than that not including the other parts & materials used. Prices varry from the mini 2' long I construct , to the commercial systems as large as 10 feet wide. I have a website showing all my small miner Sluices. And commercial are by special contact.

[@trumpsahead]

Another great design discovery, but a "machine" it is not as far as I could see. What was the inspiration, a house roof gutter? With a few more videos of this thing in operation most prospectors will be making their own for sure, just like the $400 spiral wheel ripoff, a great design but ripoff price. In any case, thanks for the inspiration.

[@XGrumpyProspector]

Here's the DEAL: Since you prefer to bash a product you cannot properly use. I ask you to send me a sample (one 5 gal bucket of your beach material) from the exact site you claim the system will not work.( I WILL PAY FOR the shipping cost) I will run your stuff, video the event in live action, & post it for all to see on youtube. If you have Gold I will capture it effectivly. Please send back the unit, If you couldnt afford it, you should not have purchased it! I will reimburse you for the cost

[@KAYAPOGAN]

Thx a million 4sharing w/us. Good luck! By da way how deep is it, do u mind 2tell us?

[@chadjones4255]

Looks like the water speed has to be very precisely controlled.

[@XGrumpyProspector]

@tildens100, Black Sand? What Black Sand? : ) Check out my other Videos, Black sand is not even an issue for collecting Gold much smaller than black sand in my system. Far better than a Bazooka, (sorry to say). The UnderFlow truly gets Gold. E mail to: [e-mail] - Tommorow (March 14, 2012) in the afternoon when I open that email for Buisiness & Responce. Thanks you for your interest and comment.

[@markcrum2389]

Are still selling your product or did you quit

[@glenngarcia3241]

My opinion is as a final step to recover your gold from processed dirt,its great. But as for feeding shovels into a river sluice or high banker set up of this,its a massive FAIL as one can't be fiddling with them things in the underflow whilst adding shovels of dirt into it!

[@ashanta5000]

+glenn garcia make it fifty feet wide and use an excavator and a hopper as an interface lol.... It'll work!

[@noneya96]

How do i get one or make the box ?

[@adamwhite4247]

How much for machine

[@mccoylindquist3227]

How much are these?

[@bottle17528]

You claim this to be a fast way to get the gold? It looks more like a cleanup tool to me, in the video you can watch the underflow riffle being lowered slowly. I bet a few larger rocks would kick the gold right out. It looks like you used chunky gold and play sand for the test. How us it operation with continuous shoveling and black sand in the sluice. Seems almost like a time wasting sluice that's not worth the money and will loose gold under field conditions.

[@spiker84]

I use it for cleanup. In the field I just cant process enough material and have to be constantly monitoring the traps.

[@marymayberry1156]

[@kf4dcy]

build a rocking system run off a small water flow hydraulic motor inline with the hose that feeds the system and attach it to the under flow vain.

simple as that very nice some have water spiral and pan looked like they were complicated setup yours is 100% better simple over flow with divider wall slight angle for water flow

[@got2kittys]

No flour gold in there?

[@wayneakins3644]

I have one and it works wonderful

[@dragonskinstudio]

looks like its working perfectly

[@XGrumpyProspector]

I have pulled fine flour and micro Gold from material that was run through a Blue Bowl. That material was mostly black sand and the UnderFlow captured all the Gold the Blue Bowl missed. Email us at underflowsales@grumpyprospector d0 t c 0 m if you have any other questions. I'm happy to answer.

[@XGrumpyProspector]

Check out the website link in Blue under the Video here, and you will get the info there

[@123Goldhunter11]

But that's pretty coarse gold. How about powder gold?

[@bossmcasskick4051]

It's not going to catch powder gold because the water flows too fast in this one. However, if you have a second underflow sluice with a slower water flow, then you will be able to catch powder gold. The easiest way to do this is to simply have a bigger underflow sluice after the first one. The bigger it is, the slower the water will flow.
