Hi, All!

This is a new thread, inspired by the 2004 thread I started when I first got my hands on the old "Gold Separator" tiny unit which I purchased off of eBay on a hunch and then wrote about here, when Gat chimed in and helped make it work better but not as good as what I'm introducing here today.

Here's the OLD, Original CP forum thread from 2004:

Old CP thread I started on Gat's and My tiny gold separator

Here's my existing unit, GOLDIE I call her, which I'm currently beta testing for Sluice Goose Industries out of Albany OR which has not put these into production yet:

Attached Image

THIS ONE, My GOLDIE, totally HAS ME JAZZED.

Miner, Refiner, and entrepreneur, David Emslie right there in your sweet state, Denise, has seen this at the GPAA shows since May of 2018, and is also Jazzed about this unit and its performance for his reclamation mine which will be online in the next 5 weeks, and start chewing away at those tailings piles around his site. Colorado Approved, and county licensed, and lining up the old mines in the area, Dave wants to use units like my GOLDIE which John built, instead of totally relying upon gynormous tables already built and ready to be site mounted.

David Varabioff of "Motherlode Gold" (GoldBay Gold) is jazzed about getting his hands on a Goldrop unit shortly for his Colorado Quartz Gold Mine in No. California. Yes, the one he sells paydirt from and also finds those scarey beautiful Crystalized Gold Specimens, which just take my breath away.

Thirdly, Yuba Industries, a well known-- at least on this left coast-- miner, is also Jazzed after their initial salted cons test returned very high percentage of gold in their run of table cons when they just completed testing Goldrop. Salted 14 grams, recaptured 13g, aka 93% capture. I know nothing of the mesh sizes nor the composition of the con, nor the beginning weight/volume of cons, just got the report.

THIS 31" unit (adding the changeout catchment jar at the bottom of this "goose" adds another 5" in height), is a verrrrrrry small footprint unit and I predict will obsolete Shaker tables in both speed and rate of capture in the very near future.

This unit, since it is a closed system ELIMINATES the skating/kiting High Corey Factor gold losses from those flat, FLAT gold flakes, and all the floaters, too. ALL THAT, yes, They ALL end up in the catchment jar, and thus into your snuffer bottle for taking directly to the bank, and in short order. This is so satisfying.

I can process a 5 gal bucket of 3/16 screened cons in my GOLDIE in less than 20 minutes, and smile like a Chesire Cat.
Uses an 1100 GPH bilge pump, only 3 AMPs DC, and a gallon a minute. This is IDEAL for portable Solar Panel constant charging while processing, AND a recirc system, since it uses a gallon a minute in water.

I LOVE my "GOLDIE!"

Let's visit about this, CP'ers!!

Glad to be back with such good news, after 15yrs "doin' my thang" but never far away from my pan...which, BTW, I've traded in for the fabulous GOLD CLAW pan. WHEW!!! This is a WALK-OFF, 2 - Run homer to use Colorado Rockies' Baseball color commentary!!!

Thank you, Denise. So good to "hear" your voice again, in this forum. I have been gone a long time. Yes, this is quite the adventure. The gold is so pretty and yellow which gets caught in the jar at the bottom, I'm really tickled.

I'm trying many dirts from multiple sources. I have been also using a DC powered sieve shaker for the top of a 5gal bucket unit which makes short work of the classification process. Since most the gold I have access too is pretty small, this just helps my time on the GOLDROP to be more effective.

This elutriation process is the BEEEEEEE'S KNEES! LOL

Here's what it looks like when it's not set up and I want it moved. (Well, sure I could carry it...it only weighs 9# after all) Somebody had to take the pix, right??? I'm no good at the "selfie" stuff. Attached Image

BTW, Just out of curiousity, I took a GC tray WITH vortex mat to the USPS to put it on "official scales". Then I multiplied, 1 tray x 4 to get the 4-stack GCube weight without pump or stand.

DIMENSIONS:
GOLDROP : 9 lbs total.
GCUBE 4 stack: 22 1/2 lbs total

HEIGHT/LENGTH
GOLDROP: 31" stem to stern
GCUBE: 4 Stack 20" top to bottom

GIRTH/WIDTH

GOLDROP: girth--> 2" Diameter
GCube: girth 13 inch width

These are just some comps I thought to measure.

ANNNNNNNNNNNNND, then there's this:
I don't have to wash out the GOLDROP like I do the GCube trays/mats, NOR pan out the GCcons out of the GC mat, etc.....
Elutriation does that collecting and sorting for me, and collects the gold into an unbreakable jar at the bottom. VOILA

TIME FROM BUCKET TO GOLD IN HAND: using scoop and plop method:
(and yes, I'm working using putting my continuous feed, Joel Farmer of USProspector, vibratory hopper in line for this GOLDROP Not happy with GCube surge and scour feed system. I'm scooping and plopping with the GOLDROP, too, currently.)

Scoop method of 5gal bucket
GOLDROP: 5 gals raw material every 20 minutes or less.
GCUBE: haven't ever measured that one. Maybe someone would chime in and tell me how much time it takes to run a 5gal through a 4 stack? I truly don't know.

GRAB the gold, once and done >>>>if I do it right with the GOLDROP. AND FAAAAST? WHEW!
That's why I'm practicing with this test unit. I LOVE those effeciency and speed and weight numbers:

Now you see a few of the reasons I'm so jazzed with this puppy!!!!!

This is my own photograph of my running through Cape Disappointment Blacksands Beach Gold, (Ilwaco WA--mouth of the Columbia River) on June 22, 2019. I was invited to participate in an official field test with others who had already learned how to use this GOLDROP, and I was the green newbie. Only seen it at GPAA shows. I'd never touched it before and was there to learn. I was scooping and plopping into the funnel as I was shown how to do, and this was what popped out of my first 5gal bucket of blacksands.

The size of the feedstock was 3/16ths. YES, I had my "Pocket Pan" , the smallest size GOLD CLAW into which I dumped the contents of the catchment jar. That's the unusual shaped pan you see the gold in when I'm taking a snapshot.

The largest piece below, that oblong one, was -15, the next larger pieces were -20 mesh. The bulk of the deposit were easily minus 200 mesh and smaller.

Part of the reason I was so excited about the gold pictured, the larger mesh pieces were very HIGH Corey Factor Gold flakes which would have kited right out of a normal sluice, dredge, GC, etc. Since GOLDROP is a CLOSED system, nothing floats away, Corey or the tiny "floaties." AND!!! We were on beaches which are also clam beds, so NO JET DRY nor DAWN DISHWASHING surfactants can be used. With GOLDROP, I didn't need them. YAY!!!!!

THRILLED ME!

I'm continuing to dial in this GOLDROP these last 7 days, and am pulling some amazing gold. Now, please realize I'm not the world's best photographer, but I did manage to grab this pix, complete with my first ever photo with a silver dime in it (which I got in change at the hardware store 2 wks ago)

This particular photo GOLDROP captured gold is from roughly 2 gallons of concentrates from north of Boise in a Mining Region everyone likes to drive up to, near Idaho City, ID. You Coloradoans have your Idaho Springs, we have our Idaho City. LOL

This is some very very small stuff, and it's beautiful!

I asked Denise for permission to post a video from the inventor of this unit, John Richmond of Albany OR. She said yes. I'll put that in the next reply to this thread.

Inventor of GOLDROP elutriation tower (2" diameter individual prospector model) posted a fascinating short vid clip on the company website on Labor Day Monday, this week.

The backstory is, this was material sent to him by someone who has a hardrock mine, who'd pulverized a sample down to "talc powder" size which is pretty generally accepted to be approx. MINUS 200 mesh (<75μm) That's pretty fine. The payshot/results of what John pulled, from this man's ore shows the versatility of this unit. After wetting it into a slurry, pulverized WET MUCK, John poured from a miner's tin water cup and into the Goose. Obviously, it wasn't pre-screened, the -200 is the general estimate. You can see how fine it is on John's fingers in the video. Watch in amazement at some of the sizes of gold flakes John's GOLDROP grabbed for Don were waaaay bigger than -minus 200. Just shows the versatility of this unit, all in the same pass.

John shared that mine owner Don was told by the assayer Don took his ore sample to that he was going to have to agree to "a fee for pre-treatment" of Don's Ore: $14,000 to remove the iron from Don's sample, and THEN he'd perform the assay for the curious mine owner.

Inventor John gave Don his gold answer, and in about 5 minutes. See it happen right in front of your eyes.

It's obvious John is proud of what he did for the Don, and of course, he's sending Don back his gold so he can examine under a microscope for more information, or to go ahead and pick another assayer to determine purity, etc. OBVIOUSLY, the bulk of the "iron" is gone. extra_happy.gif

A question has arisen from a reader on another forum: (go ahead, join CP. Denise won't mind a bit, will you, Denise? sign0016.gif

"How can there be bigger gold in a crushed sample's results than the -200 mesh crush?"

Good question.

Just because the ore went through a crusher that crushes down to -200 mesh does NOT mean the gold will also be
the same uniform sized result, as the crushed host rock.

It can emerge in larger form due to malleability of the gold vs the iron in this instance. And smaller than -200, too. Same holds true if the host is quartz, or any other mineral host.

This newest vid (link above) of John's work with Don's sample is visual illustration of this reality.

Well, I'm having more fun than a pig in slop, as they say down on the farm. signs026.gif

I've been continuing my experiments with this fabulous GOLDROP Elutriation tower of inventor John Richmond, Sluice Goose Industries, Albany OR. It was approximatly 11 pounds before the bilgepump, etc., and I've got it down to under 7 pounds now, and have it mounted onto an aluminum tripod what was originally an easel tripod, with extendable aluminum legs.

It is such a joy to set up, and run now. Where as my 5'7" frame could barely see over the very large hopper for the he-males amongs us.

One of the things I've also done is change out that gonzo black, OEM round hopper of John's for a sloped bottom, offset, automotive funnel. Inserted into back of the red funnel in the pix, I've slipped the top water feed so that it makes a gentle arc and due to gravity, the 1/2# of cones slips and slides at a pretty steady rate into the funnel neck and down into the tower for separating then capturing.

I'm having so much fun, primarily because I'm seeing gold in darn near every capture jar that I dump into the regular sized GOLD CLAW when I empty the capture jar, which is often now that I've got this working jiiiiiiis right!

The relaxing sound of falling water out of the tailings pipe fitting, and the certain knowledge that I'm more than 95% guaranteed to get at least some color out of everything I'm running whether from local creeks, sandpits, Oregon beach cons, or sacks of "Washed" Quik Crete sand from HOME DEPOT, or black beach sands from Cape Disappointment in Washington State, you name it.

I'm seeing gold.

Boy, seeing gold every darn time takes the work out of running and finishing off "run of mine" or all the potato salad containers of cons I've never finished up until now, from years and years and years ago.

I'm operating now this test unit as primarily a finishing machine...only running material from -20 down to -50. Since I can clearly see through this unit's crystal clear elutriation chamber, I know when the material has worked down the same con twice. Then I crank up a specific value increasing velocity, send the gangue spinning up and into the tailings tube, CLOSE the gate valve above the capture jar, untwist it, empty the jar. VOILA...all those pretty gold specks and flakes. JUST WOW.

I haven't had this much fun since 1988 when I first learned to pan and thought I'd died and gone to heaven, getting to actually do THAT one on my bucket list.

I can't wait until this thing is on the market for the rest of you, that's how close to being done with the testing that John has me doing.

Just had to check in and give an update.

Hi, Denise et al...

I'm happy to return from the blackhole of the internet and let you all know this GOLDROP is now officially for sale, as of the first GPAA Gold Show TUCSON AZ this past weekend.

The new North American Distributor for the entire continent is a well-known and highly respected gold miner and fine, cordial character, Dave Varabioff, of Motherlode Gold. Dave almost single-handedly cleaned up the wild and wooly eBay gold paydirt and nuggets business of 20+ years ago. And he's earned himself the right to be the Point of Sale contact for the GOLDROP.

The price point is now established, in two tiers: on the basic unit, with bilge pumps, hoses, etc., and comes boxed in a 9x9x9 by 42" sturdy cardboard box, and the other option, is the one with the two stackable recirc 1-30gal and 1-20gal barrels and shipped anywhere in the world in a steel retainer ring barrel. $500 more if you want the 2 barrels recirc model where you can leave it set up for days in the interior when you're off the grid.

John Richmond, the inventor, just completed an exciting set of artisanal miner trials under the watchful eye and invitation of the small miners association in Ghana, West Africa, the Department of Mineral Resources of the Ghanian govt, and the primary University in Ghana's Geology department.

The govt of Ghana has joined with 9 other nations in what is called the "Tokyo Treaty" to eliminate and outlaw the introduction of mercury into artisanal/placer mining in that nation. The govt of Peru just made a big splash as they seem to be the next in line to announce their intent to get serious about pulling mercury out of mining.

The Ghanian representatives, local, educational and governmental are so jazzed about the GOLDROP, they have already sent an official letter to Mr. Richmond of Sluice Goose Industries, Albany OR, announcing their delight, extending their deepest gratitude for coming and the demonstration, and indicating a desire to further collaborate in distributing the GOLDROP, especially in Ghana.

Another primary distributor (outside of USA sales) , Mr. Toby Pomeroy of Mercury Free Mining was the one who headed the Ghanian delegation for Mr. Richmond.

I'll post photos later of the set up, NA Distributor Dave had at the Phoenix GPAA show just concluded.

It's getting real, folks!!!! Stay turned. I'm as jazzed now than I was back in early summer last year when I got my beta test unit shot at working with this amazing, technology disruptive ELUTRIATION gold separator, All 7# of it, sopping wet

JUST IN: Dave Varabioff of Motherlode Gold's famous Colorado Crystal Gold Mine in California, has just posted his official demonstration unit photo of the GOLDROP he's now North America's only Distributor for. He had this set up at the Pomono Cali gold show a week ago.

One 5 gal bucket for a clean water reservoir (or recirc into for cleaner water), and 1 5gal bucket for holding his goldpan to pour catchment cup gold contents into!!!

Oh, and a catch bucket below this 32" unit for catching any drips from unscrewing catch cup thumbsupsmileyanim.gif

Goldrop with Run of Mine Large Funnel intake


The LARGE FUNNEL for cramming through 5 gal buckets in a hurry for testing, and the small funnel--scroll up 2 posts, the small one is "red"===> for finishing to capture anything below -100 consistently!!! (I get down to -300 using this incline funnel) Sure beats panning!!!!!!!! And eliminates RP4, which I sold, and has mothballed my Angus MacKirk "Orofino" aluminum deck shaker table.

Three new developments in the world of GOLDROP gold separator tool for miners are mentioning.

1) It just had its first genuine field test in the desert around Duisenberg and was successful. While others were creating billowing dust clouds enveloping themselves and their dry washers, etc., inventor John Richmond hauled 2large 5x5x4’ cubed‘ containers of water to his dig site, and recirculated his water,, and got not only the larger pieces the dry washers were producing, but also the fine gold aka tiny gold that the dry washers blow right out of their units.

2). John had Alum As a floc available but chose to not use it in his recirc system.

3). John has now installed a. Magnetic gutter sluice between the discharge pipe and and the settling pail sitting atop the recirc blue 33 gal water buckets, to passively capture the blacksands before entering the tailings. This all but eliminates his preferred use of 5e Spin-it Off rotary blacksands separator upon discharge.

And finally, John is experiencing my deliveries now that Dave Varabioff turned over th KellyCo company the exclusive USA distribution rights, selling directly from their own two showrooms as well as online. So many ticked to death users of this latest greatest tool to hit the goldminer market place.

If you haven’t seen this demonstrated yet, the videos keep coming as miners all over the western USA in particular, send in their “discards, and problem ores, and watch John pull their gold out for them in test after test after test.

Recognizable Gold YouTube videographer, teacher, gold claim owner, and long-time Patreon content creator, prospector/adventurer Dan Hurd, is one of the newest users of the Sluice Goose elutriation gold separator, GOLDROP which I have been featuring on this forum since about May 4, 2018 when I spotted it in person at a GPAA gold show in Boise ID before I became the first outside the family, individual beta testor. KellyCo is now the national distributor and doing a fine job.

Dan has some pre-YT. full-color publicity stills currently in a collage format, and now out on the net, advertising his intent to demonstrate and showcase his use of this new fascinating GOLDROP tool in the goldprospector's universe.

Stay tuned for my follow-up post, with the url to his new YT when it is released. OR, go ahead and beat me to posting the link. Won't hurt inventor John Richmond's feelings in the slightest. thumbsupsmileyanim.gif

Get out and get some shiny this year. Enjoy the hunt, Colorado Prospectors, and the rest of us!

GOLDROP inventor John Richmond, reported this 14 of June 2021, in another forum that he is shipping three units at a time per day more frequently now, now that word is getting around and more satisfied buyers look at his price, the price of gold and do the math, especially in light of the time savings and portability of the stripped down 7.5# elutriation unit. KellyCo is doing a fab job nationally rep'ing for him. And as his original Beta tester, I couldn't be happier. The following graphic will help put the cost vs relatively quick cost recoup argument into quite sharp, favorable bias relief. (vc.13,398)

Yes, the trusty Garrett Green GPAA gold pan
