  You know you’re a prospector when you destroy gold, to find a better method of finding gold. 😂. Great work as always and thanks for sharing

  I suspect your table recovered over 95%, and the wet panning of ultra fine is where the 25% was lost.  black sand and micro fine gold are nearly impossible to separate with panning. I suggest running the cons 3 or 4 more times to get down to a few ounces of cons.   The table you have created is exceptional.

  Great vid! A nit-picky suggestion: I read somewhere that "black sand" is probably part hematite - which is SLIGHTLY magnetic. I built a magnetic pickup "thingie" that had a hocky puck shaped 1" "52" magnet with a center hole for attachment to a dowel - that would slide thru a 1" pvc pipe - like the one you have. I squared the end and glued a piece of the thinnest plastic film I could find (a piece of a cigarette pack) on the end. I could, in fact, pick up more "black sand" than I could get with a setup like yours - not a lot, but some. I notice that your "result" that you weighed had enough black in it to discolor it. Because Gold is so gol-darned heavy, the little "black sand" your magnet didn't catch probably is less than the accuracy of the scale you have, but it IS something. Like I said in the beginning, nit-picky, but might be interesting to check - because you're SO AMAZINGLY PRECISE with everything else (a great thing!).  By the way - it's a pleasure to see some real science in a prospecting vid - I'm in awe!

  Hello Dave. Great little machine you have. Like your attitude about not building it for sale. Just getting your concept out there. As a desert rat and inventor myself, &nbsp;I appreciate your thought process. <br>Here&apos;s a simple name; &quot;The Earthquaker&quot;. <br>Peace, and may the shiny be with you!

  Incredible work! You are doing nothing less than overcoming what was previously thought to be impossible: recovering minus 100 and -150 mesh gold using dry processing methods. This is very innovative, and to my knowledge has never been done before. Keep up the amazing work! &nbsp;P.S. Name ideas: Ultrafine Mini Shaker, Micro Shaker, Nano Shaker, Shake N&apos; Take, Micro Shaker 200, The Gold Getter, Micron Gold Machine, Micron Gold Getter.

  Your panning example and tip is pretty legendary... never have I ever heard anyone mention such an acurate and super tiny but meaningful detail.

  This device is so fast that you could easily triple-run the tailings

  Hi Dave. Great achievement, congratulations. This will help many people. Thank you for your generosity in selflessly sharing your knowledge and resources. I made the water table, but I got the weight wrong. I went a little overboard with the thickness of the aluminum I used for its structure, and it weighs 7.5 kg with everything, including the magnets. Since I&apos;m building other basic equipment (mill, filters, roaster, and oven), I&apos;m putting the table modification on hold. But I&apos;m sure I&apos;ll fix it soon and even make this new &quot;Desert Table.&quot;

  The potential for this in places where people don&apos;t have water or can&apos;t get a water permit seems pretty big to me.<br><br>Very impressive.

  Hahahahaha! The anxiety of your dumping that gold into the sand was definitely a shared emotion, your honest and un filtered reaction was very much enjoyed and gave me a good heart felt laugh! You&apos;re a true gem of an individual sir, absolutely a pleasure to watch your videos.

  Very amazing work Dave. Looking forward to the build video.<br>As far as a name &quot; Dave&apos;s 10 Hertz dry table&quot;<br>Or AU oscillator.
