What is a High Banker? Consider a
sluice box, similar to that described in the Sluicing page, mounted on a
4-legged stand that gives the sluice box the correct slope. Then, mount a box
(called a Hopper) at the top end of the sluice box that gravels are shoveled
into. In the hopper, put a "grizzly" which is a series of rods sloping
in the box that will filter out larger rocks. Also in the hopper, put one or two
"spray bars" that shoot a spray of water onto the gravels that you
have just shoveled in. Add a gas engine with a water pump and some hoses to get
the water from the pump to the spray bars and you have a High Banker.
When you shovel in gravels into the
hopper, water sprays onto the gravels. Anything that is small enough to drop
through the Grizzly enters the top end of the sluice box. Anything to large to
fall through the grizzly falls, or is scraped of with a shovel, into a pile
directly behind the rig.
When the smaller gravels fall into
the top of the sluice box, the water from the spray bars begins washing out the
gravels just like in a regular sluice box. The sluice box has riffles, carpet or
miner's moss just like a sluice box. In fact, High Banking is often called
Just like pans and just like sluice
boxes, High Bankers come in a large variety of styles and sizes. The small High
Bankers often come with a pack frame so the high banker can be backpacked to
remote locations. The largest high bankers often are a combination of dredge and
high banker, giving the recreational prospector the option of high banking or
Differences in riffles, spray bars,
carpets, miner's moss, engine-pump combinations, hose and frames all contribute
to a seemingly infinite selection of high bankers. I suggest getting the largest
High Banker-Dredge combination you can easily handle and can afford.
High bankers give you the ability
to bring the water to you work site. Sometimes, gold bearing gravels are located
some distance away from a water source, or the water source is not conducive to
using a typical sluice box. The high banker pumps water from the water source to the
worksite, so you don't have to carry buckets of gravel back to the creek.
One disadvantage of the sluice box
is that most states require the use of settling ponds to settle out the solids
in the discharge water before that water enters the creek. The fear is that the
murky water produced by the high banker will kill fish. It doesn't matter that
those same fish survive winter run offs every year that are a million times that
of any high banker, but that's a subject for the SOAP BOX.
High Bankers are an excellent way
to get involved in recreational prospecting. High bankers are moderately priced,
come in pieces for easy transport, and are very efficient.
