    Hello,

    I’m a new prospector working in an area that primarily has small flakes. I’m usually working tailings piles or areas that have otherwise been processed by heavy equipment in some fashion, so not really expecting to find nuggets or larger pickers.

    My question is how far should I classify my concentrates prior to running them through the Gold Cube? Currently I run them through 1/2, 1/4, and 1/8 wet. The smaller mesh gets me more material per bucket but I wonder if it’s worth the extra hassle and if I’m risking losing a small nugget. The 1/8+ material left on the screen is not easy to quickly sort through when I’m looking for nuggets before dumping (and I don’t have a detector). The smaller mesh also clogs up quicker. My material isn’t heavy clay but does have a lot of sand.

    I’m interested to hear what other’s experience has been with Cubing 1/4 vs 1/8 with respect to gold yields and time spent classifying. If I stopped at 1/4 I would double my material volume but buckets are cheap and running material through the Cube is much less work then using a screen.

    Thanks!

    Turns out that 3/16 is the minimum you need to classify to in order to run through the gold cube according to multiple sources so I think I'll stick with 1/8 as it's the closest I have. I thought I had read you only had to classify to 1/4 but apparently not. That trommel is looking real handy...

    To add to the good info here already. I have exchanged my Vortex Matting in my Cube to Deep V on top, micro mat dream mat, Vortex, and last at the bottom is saw tooth mat. However i know for a fact that now that Dream mat has the Micro mini mat as well i will change out the Vortex mat in the 3d tray with micro mini dream mat. the reason why is you can accommodate a bit bigger material but you will most certainly increase the feed and the amount of material you can run through it but most importantly the recovery is second to none with the dream mat and micro mini dream mat.
    best to you

    I run 1/4 with the dream mat on the top 2 trays and gold cube mat on the bottom trays. Rarely find anything past the 2 dream mat trays so I’ll usually clean up every 10 buckets and only clean the top 2 trays it’s quick then back to running.

    On a side note I metal detect my toss piles of rocks when I’m done just to be sure I didn’t miss a dirty old nugget.

    Hope that helps

    I have the trommel, bought it because you just can't run material quickly through the punch plate screen that comes stock with the cube unless its beach sand. The trommel is very expensive, but it eliminates most classifying for me, speeding up processing samples quite a bit. It has run well for me, plus everyone who is not a prospector/miner loves to see it run and ask about it, its definitely a cool setup for recreational use. The other miners' posts here about changing out the matting - I would recommend as well, if you are not running beach sands, also consider matting the top slick plate...

    It's been my experience that anything larger than 1/8" tumbles too hard through the Cube and can dislodge gold. You want it to flow through not tumble.
    P.S. I 'm hoping to convince my "Boss" that she needs a trommel, I think lugging a few more buckets should do it.
