a Sluice Box
part of the creek that has a steady flow of water in which to put your
box. Clear a space in the creek and place your box in the gap. Put the
top facing upstream so that the water flows through the box. The
riffles will then be at the downstream end. Prop up the top of your
one metre-long box so that it is about ten centimeters higher than the
bottom. Thatís about a handbreadth.
Ideally, you should have about a couple of centimetres of water
flowing through. Put a generous shovelfull of gravel in the top end.
If the water sweeps the bigger gravel and grit away down the box and
leaves a small beach in front of the first riffle, your flow is just
right. If it washes every bit of grit out of the box and the riffles
start to float off, it is too fast. If nothing much moves, even after
using your rake to help the big stones through, it is too slow.
When you have the flow just right, check the downstream end to make
sure there is room to receive the tailings that will be coming out of
the box. They pile up quickly and interfere with the flow of water.
During sluicing, a few sweeps with the rake or your gumboot will keep
the tailings clear of the end. You are now set to dig for gold.
Donít be surprised if you see some gold in your box after the first
few bucketfulsófine gold and small flakes donít always go down to
about this process and instructions on how to make a sluice box can
be found in our book,
"Gold for the Taking."
