Instructions
Build a snipe from 1-inch PVC pipe. A snipe is usually about 4-feet long and has a small opening at one end where the material is sucked up and a plunger on the other. Place an end cap on the snipe tubing and drill a hole big enough to insert another length of PVC that is smaller in diameter than the outside of the snipe tube.
Cut a piece of PVC to fasten to the end of the inside tubing to act as a plunger. Wrap the plunger with an O-ring to seal the plunger to the inside walls of the snipe.
Drill a hole in the side of the snipe and attach a hose and fitting to run out the side of the snipe and back to the sluice box. Make the fitting water proof with silicon gasket gel.
Clamp the loose end of the hose from the snipe tool to the top of a sluice box. Place a gold pan at the bottom of the sluice and run water through the sluice box.
Point the end of the snipe under large rocks and pump the plunger of the snipe to suck up gold ore from under rocks. Pump with the end underwater until the gold ore comes out the other end of the hose and into the sluice.
Separate the gold that was sniped using the panning method. The sluice will have separated much of the debris from the gold. Once the sluice is cleaned, the gold and heavy black sand can be separated quickly.
