Dave Urick, inventor of the SpinItOff magnetite removal tool, gave me 3 100lb. bags of Cape disappointment beach sand, approximately 12 gallons by volume. I removed the magnetite using my SpinItOff to harvest the magnetite for use in the Magnet Sluice. I then processed the remaining 9 gallons of the non-magnetite portion of the Cape D beach sand through the GOLDROP. I recovered tiny flour gold in the jar and smelt-able gold ore in the Magnet Sluice. The Smelt-able ore weighed in at 14 grains. The gold was weightless as it did not have enough mass to weigh 1 grain! That's some pretty tiny gold recovered to weigh NOTHING! More evidence the MFM/GIA report conclusions showing the GOLDROP/Magnet Sluice was the only device tested to produce a smelt-able concentrate as well as recover more gold than using mercury are points of fact!
