    Cape Disappointment/Long Beach in Washington State

    This last weekend (March 18 and 19), after the Puyallup, Washington Gold Show, I made a trip to Long Beach with my 3 stack Gold Cube.  I had talked to someone in the Southwest Gold Prospectors (GPAA) club in Vancouver, WA to try to find where to go on Long Beach that I could drive onto the beach with my equipment.

    I found a site that I could use fresh water to run the Cube and ran 7 buckets of black sand through the Cube, then cleaned the cons from the Cube to take home.  Being taxed for time, tide and weather, I also took 7 buckets back home to run (which I haven't gotten to yet).  Did not need to pre-classify the sand - it's that fine.

    Ran 2 teaspoons of the cons at home in a small cleanup pan and actually found gold!!  Had probably 100 pieces of -100 mesh gold in my pan.

    Can the Gold Cube work well with extremely fine black sand??  This stuff seems fairly small and packs into a pan to the extent that it is almost impossible to pan in the usual manner.  It just sits there.  You really need to keep amounts you pan to very small amounts.

    I can see where the Spin Off magnet for pulling out black sand would be great.  Saw one demonstrated at the Gold Show, but couldn't justify one at the time because I live on the opposite end of the state.

    Wayne,

    I would run a test at home with black sand and the cube. My understanding is that Mike Pung and Red created the Cube for prospecting the black sands along Lake Superior, so, it should be tailor made to that use!

    I have had zero issues with running a 3 or 4 stack in heavily mineral dirt/sand in GA.

    Brad,

    Thanks.  This stuff is all extremely small, some of the smallest black sand I have dealt with in quantity.  My post was wrong about my cube.  It is a 4 stack, which I understand will catch pretty much everything.  I haven't tried to find out whether the lowest mat is catching anything or not, but would be fun to see if it is or not.

    When I run 4 stack, I have never found any values in the bottom stack. Very rarely have I found anything past the first carpeted stack.

    I run it hard with a bigger 1/4" punch plate Crisson Gold Mine made gold banker classifier and sometimes do not even remove the potato size rocks from local streams and have not seen any loss of values, ever, in my tailings.


    I have run two pumps, 1 for the highbanker attachment at about 1300 gpm and another pump on the cube itself, valved back to ~1000 gpm, based upon the 3' head calculation. I have found the Johnson pumps to be the best and most durable for the money. They really move the water and Amazon has free expedited shipping if you join Prime...which pays for itself in 5 shipped items.
