    I love that design! Perfect for us silver haired guys. It will gradually walk us into our senior years (pun intended)........there ain't no place that we can not get to. Those 2 wheeled walkers have many uses.

    Hi John,

    Just finished my test on the mat you have pictured above.

    The first thing I noticed after turning the water on before running any material was that the mat traps a lot of air bubbles.
    A hand spanking of the mat took care of all the air bubbles (something I learned to do with the vortex mat/rough top conveyor belt)

    Another issue that I wanted to address was the transition from the sluice bottom to the beginning of the mat.
    I found that a thin piece of aluminum flashing 2-3/4" x 10" held to the sluice with waterproof double sided carpet tape worked great.

    The first 2" were in front of the mat and then 3/4" was bent up and over the leading edge of the mat.
    Made a smooth transition and held the mat down as well.

    At the foot end of the sluice across the bottom I attached a 1/4 tall aluminum molding to serve as a stop for the mat and to do double duty as an anti migration baffle to stop any gold that made it's way underneath the mat from washing off the end. Very important.

    Ok, now to my test results.
    First, out of curiosity I wanted to see what would happen if I just ran my 2 gram sample of assorted shape and size gold by itself.
    The gold consisted of large pickers down to fly poop size, some was coarse some was fine, some flat, some round.

    I sprinkled it into the hopper and waited 5 minutes before shutting the water off.
    NO gold went past the first 3" of mat.

    I cleaned the mat, dried and re weighed the gold to make sure I had it all.
    Then I re-started the water, spanked the mat, and ran 2 gallons of regular desert material classified to 1/4" that contained no gold to load the mat.

    Without stopping I then ran two gallons of the same type material but with the 2 grams of gold mixed in.
    Then ran another 2 gallons of sterile desert material before shutting down to do a clean up.

    I also had placed a tub at the end of the sluice to catch all the tailings from when the gold was introduced until shut down.
    Could see that a lot of gold was trapped in the first 3" of mat. Before removing the mat to clean it I adjusted the legs on the sluice frame to level.

    Then I used my long tweezers to check the mat riffles to see if I could tell how far down the mat that the gold had traveled.
    The best I could tell was that no gold made it past about 12"

    After panning the material in the mat by hand and then drying it before weighing, the 2 grams of gold was all accounted for.
    I felt there was no need to pan the tailings.

    I know this test was just my one experience with my setup and my material and gold. Your results will most likely vary.
    My opinion of this mat so far is that for what I am going to use it for, it does a great job!

    Hope this helps.

    Well, that sounds promising. Did you screen all your test material to 3/8"? I was planning to run mine using my 1/4" grizzly. I also have a 3/8 in mesh which I sometimes use. Trial & error I guess.

    Tomorrow, if the weather cooperates, I am going to go down to the river, screen some river gravel to 3/8 inch, maybe a 5 gallon bucket, then run it through my fluid bed concentrator, discharging it on my cleanup sluice, then save the all the total concentrates from cleanup sluice plus concentrator.

    I still need to prep my highbanker hoses and service my water pump for this year. Last year we had the river breakup already at this time of year. The river is still frozen over, except for the odd spot, where gravel is exposed.

    My bad, for the test the material was classified to 1/4". The grizzly bars on my hopper are spaced at 3/8" for running unclassified material.
    I edited my post to correct the error.

    Awesome to find this information guys! I built a beach box that runs exclusively vortex conveyor matting that captures North Saskatchewan River gold as good as I could ever ask for, but the box is 24" wide to keep up with sandy material at the slow flow rate required. I'm very interested in the new mats out there for NSR gold.
    I'm interested if any of the mats you've tried do any better than the other when it comes to 'less than ideal' setup and flow.
    Something that can handle imperfect water flow and maybe a tilt in the box here and there any better than the others? I've never actually used real miners moss under expanded, but do like the newer style mats for easy cleanup.
    Anyways, Hello to all, looking forward to going back and reading some more posts!
