Operation: In order to operate the Le Trap sluice in a stream, you will want fairly fast water. The closed end of the Bank Robber Sluice can be cut out, creating the River Robber Sluice.

Step 1 Setting up the Sluice

Locate a place in the stream with fast water and a gradual drop. Water should run fast enough to move a 1 to 2 rock through the sluice about as fast as you can walk through with your fingers. You may have to remove or rearrange rocks to provide a space for the sluice to set so as to provide approximately 1 ½ to 2 of water uniformly at the proper speed. Rocks upstream may have to be arranged to divert water either in or out of the sluice.



Step 2  Holding the sluice in place.

To hold the sluice in the river, it is suggested to put a 1 x 4 x *5 board or aluminum angle across the sluice at the narrow section. This board will allow you to place a rock approximately 5 to *0 pounds on the board to hold the sluice in place.  There are many other ways of making a rock holder for your sluice box.

Step 3 Processing the material.

Deposit the Gold bearing material in the flat portion of the sluice and allow the water to wash it through the sluice. Feed the material into the sluice at the rate that will allow at least one ridge to be seen all the way across the sluice.  The amount of material that can be run will vary from one location to another, depending on the types of deposits in the area.



Step 4 Clean out.



When you have processed the bank material, allow clear water to flow through to wash out any excess lighter material. When the sluice is ready for clean out, lift the intake end out of the water first. Pick up the sluice and place the lower left corner into a bucket or Gold pan. If there is Gold in the lower end of the sluice, the angle or the water flow can be changed to correct this.
