  1. Hi there RR, All this gadget is doing is mechanically classifying material into a gold pan. Nothing you couldn't do with a manual classifier over your gold pan which you could possibly get away with. I know with my sluice boxing I made & use a bucket classifier than can process a lot of material pretty quickly to feed down the box. Clean up time Good luck out there JW
  2. Super Cool! If it can handle the punishment of Hardcore Diggers? Enjoy! Cheers, Ig
  3. I have been working on this for a couple weeks. It's a collapsible, customizable, self-contained, super light, 3D printed sluice box! I know there are other folding sluice boxes, but none of them actually fit in a backpack, or are light enough to carry in one hand. This solution would be EXTREMELY helpful! I'm on my phone trying this, so when I get to my laptop, I'll write in a bit more. So I'm currently in the CAD stage. I have a guy that does 3D printing for me, and his machine is limited to 12"x12"x15" so I might have to shrink the size of the project down to fit, as I don't have access to, or can even afford, a larger 3D printer. I have this up on Patreon to attempt to raise some funding to start getting prototypes printed, and boost this project towards the finish line!

  4. I tripped over this extensive article, available as a free download. Here is the abstract: The article sets out to clarify the special character of the North American gold pan and why it remains so popular – in spite of widespread dissatisfaction and many modifications and innovations. The North American pan is distinctive in being circular with a flattish floor ringed by an outwardly sloping wall. Its identity is confused by over-use of the terms 'pan' and 'panning'. The North American pan gyrates in a distinctive orbital motion driven by both hands of the panner. Although many other motions are resorted to (tapping, to-and-fro, tilting, and tick-tock), it is the orbital motion and flattish floor that together distinguish the pan from most other hand-held gravitational devices. In spite of its enduring popularity, no scientific tests have been published on the North American gold pan or for any of the innovations covered by 30 US patents awarded since 1861. It remains unclear if the North American gold pan is more efficient at recovering fine gold and flat gold than is a lotok, batea, dulang, ninja bowl, grizzly pan, mat, bucket or any other sort of hand-driven gravitational device. Some innovations are long-forgotten but merit attention. For instance, bars to keep the panners hand clear of the water, cables to hold large heavy pans, and several pans designed for panning without any water. Traditionally the North American gold pan was a combined digging and washing device, but today most models are not designed for digging and require a spade to be used.

  5. Check out my new setup for those remote areas where gas powered engins aint allowed
  6. Unfortunately due to weather my plans for a gold hunt today are destroyed. I was going to hit my favourite creek with my sluice. It's a Keene A52, I normally run the gravel through a 1/4" classifier before putting it into the sluice and I am finding quite good amounts of gold, even the tiniest little flour gold bits are staying in the sluice. The creek has quite a good fast flow and I've never had an issue with the sluice not handling my gravel, is it necessary for me to classify and am I using the right size classifier, it sure slows me down a lot but I don't want to lose gold by just shovelling straight into it. Also, is it safe to leave the sluice in all day, with water flowing through it while I stop for 30 minutes or so for lunch, or should I pull it out if nothing is going through it for a while? Just worried that I may lose Gold if there is nothing passing through it. Thanks for any tips!
  7. OK I am new to gold panning but I want to purchase one so I can do some sampling around my property have searched the web for what would be best for a beginner there are so many different types on the internet that for a beginner gold panner it is pretty confusing what does everyone suggest for a beginner at panning I know panning is not easy at first and there is a technique to it its a learning process as everything is thats new to someone just looking for suggestions I figure a gold pan would be the easiest way to sample and see if there is gold here and the cheapest to start
  8. I took a picture of my collection of crevice suckers for the Classifieds and figured it would make a good photo to post here for people to see a few designs old and new.
  9. Has anyone tried one of these? Looks like a versatile piece of kit! I'm wondering what kind of run time you would get out of the electric pumps on say a 29 series deep cycle battery... https://keeneeng.com/mini-max-power-sluice/
  10. Hello, my first post. I purchased a deceased prospectors never used, no brand name, no manual spiral wheel recovery system (and other goods from the son). I can add that it came in a Rubbermaid protective ultility case marked "ActionPacker", is about two feet tall when assembled on a frame type stand with control panel.
  11. Do we have any beach miners here? I'm in Oregon and do a bit of sand sifting. The Oregon laws for the beach include No Power equipment so you have to ground sluice or have a recirculator above the high tide line or above the grass line. Kind of a pain but doable. Anyway I have a thread going over at TreasureNet that is a little rambling but it will show ya what kind of equipment I use and some of the results.... Nope nothing like the Nome beaches but it gets me off the couch and I manage to eek out a little color. So here's a link to the thread, hope you find some humor in it as well as maybe a little info. too. http://www.treasurenet.com/forums/sluicing/454120-got-out-little-today.html If we get a discussion going here I will just post anything new here instead of a link to another forum. Thank's for looking. Also does anyone have any info on beach mining in northern cal.? I can't find a thing on it and I have heard of a couple very promising beaches. But I won't spend the time and energy on them and the trip without some knowledge on the regs.
  12. After researching every gold wheel available, priced under $1,000.00? The Keene GW25, 25in diameter gold wheel proves to be the most bang for the buck, being able to produce gold dust-sized gold, and feed 400+ lbs of material per hour. At $475, it can't be beat.
  13. I'm looking to get a plunger style magnet for removing black sands from concentrates when finish panning. I've seen a couple which are labeled 8 lb and 16 lb respectively. Often bigger/faster/stronger means better, but not always. Any suggestions? Does the choice matter if the material is dry (as in bone dry) or wet (as in submersed in water)?
  14. How she look ? Dose this look like my punch screens will work great and giv the material more time to wash? Giv me poiters to please!!
  15. I could use some advice, I'm running my Keene A52 Sluice in a gravel creek, I've tried the Keene BLUE CLASSIFYING SIEVE NO. 002 MESH which is 11.5mm, it seems to let too much bigger stuff through to run directly through the sluice nicely but Keene's are stackable so I was thinking of getting a smaller size for under it. I was wondering if anyone has a suggestion for the optimal sieve size for the A52? 1/4" seems like it could be the way to go? Do you recommend stacking the things? does it make much extra work or would I just be better off starting with the size I want to finish with? Thanks for any assistance.
  16. Hi Everyone Im trying to find Angus Mckirk sluice boxes on the west coast, has anybody got any ideas who sells the and where to find them.Even a few second hand ones will do Thanks
  17. Has anyone made a crevice sucker? I was thinking of buying one until I saw the price locally, cheapest ones are $110 + $15 shipping, seems a bit much for what they are, looks like people are making some out of PVC pipe but I can't find any decent plans online to use to make one. If anyone has some good plans they would be greatly appreciated.
  18. So its puzzled me why panning classifiers are solely made for gold prospecting.Surely the manufacturers must be going out of business to make these items solely for the prospecting industry.Well this is not the case.I did some in depth investigation and spoke to a friend of mine in the plastics industry in China and showed him a pic of a classifier.What he came back to me with was quite interesting. Classifiers are actually made for the pyrotechnic/firework industry hence there manufacture origin in China.Kaboom and off it goes.They are used for milling black powder and other pyro ingredients.So if you want a set of classifiers and don't want to pay $24 a piece, then check out a pyro supplies store on the internet and you will be pretty surprised when the exact same classifiers /screens we purchase for prospecting cost around $12 a piece or cheaper.
  19. Ok, I'm a newb, and maybe a bit impressionable, but this really caught my attention. It's a long video by Doc of Gold Hog, but if you jump to about 20:00 you'll just see it in action to see for yourself. It's essentially a small short sluice that is hand operated. He processes a bucket in less time that it took me to do one pan (first day of panning). I figure this is a good way to run some material quickly, without the sluice. I'm just beginning and hope this isn't a hoax, but it sure looks to make a lot of sense. Maybe someday I'll have a dredge or high banker, but this sure beats the pan for concentrating and suits my budget. Hope you enjoy the vid as much as I did!
  20. Mods to try to catch some fine gold... Cut box down to 3', added ribbed mat and punchplate. built a new inlet. Will try it out this weekend.....
  21. I understand that there are multiple reasons for panning especially when you include professionals all the way to occasional, recreational prospectors. I'm definitely near the right end of this spectrum, but I'd like to get better, faster, more efficient. To be specific, I want to find all the gold in my bucket, and I'm not trying to make a threshold cut at return per time spent. Here are some questions I have: 1) Does classification help enough to make it worthwhile to buy, carry, store one or more in the first place? (If 'no' then I guess the rest of these questions are unnecessary.) 2) What sizes should one use? I know there is an array of sizes, but how many of those are useful? 3) Do you stack multiple sizes in one operation? 4) Do you still investigate the materials that the classifier rejects as too large? For example, with the wire mesh types do you dump the contents onto a clean, metal free area and run a detector over them to make sure there isn't a nice size chunk of the magic metal in your rejects? 5) I know the GPAA sells a set of screens that you swap in/out of a single housing. Is that the best direction to go if you are going to use multiple sizes? If I've missed any important points, please enlighten me on those as well. Thanks in advance for your answers.
  22. Hi Folks, say you hypothetically had a fair amount of crushed ore to process, and due to the amount of mustard gold in quantities worth recovering, what would you recommend and why? Water can be a problem so recirculating would be good, portability is a big want, will be using mercury and a retort due to the mustard gold. Open to suggestions. Many thanks, Steve
  23. This is not exactly new since it was announced last October, but I was wondering if anyone has seen or used these yet? The new Garrett 14" gold pan has a asymmetric design and fixes one of my pet peeves, which was the small bottom area. The Garrett gold panning kits now include these new pans. Here is the new pan next to the old design for comparison...
  24. On a side note Steve, I bought my first sluice, a Keene A52 hand sluice, from AMDS back in 2010 when on my first and so far only trip to Anchorage. You built an awesome store, and the staff were super friendly and helpful. Definetly a good reason to go back there, once the exchange rate improves. Cheers! It's now the secondary recovery section on my wash plant setup.
  25. I'm wanting to recover CW Bullets faster and easier from the cracks, pockets and holes on the river beds. I'm wanting to build it out of plastic as not to interfere with the detector. It will have different sized and shaped tips depending on the size of cracks if needed. This would be an intermittent pump just for bullet extraction. It will have a longer wand that would enable me to suck lead standing in 4 feet of water. I would build a simple catch area for the outflow. It looks like Keene's smallest pump is 100 GPM/6000 GPH for their 2 inch model. I am looking at a 12 volt system and have my eyes on the 4000 GPH Johnson Bilge pump. Now my question is do you think I can build an electric dredge that can suck big lead to the surface? Any and all ideas are welcome such as size, nozzle design etc....
