Nevada:
The Next
American
Gold RushNevada has been a
prolific mining region in
the US since the fa-
mous Comstock silver
discovery in the late1800s. However, it is
now gold that draws
miners to Nevada.
Gold deposits in Neva-
da are unique in that
they cannot be seen by
the naked eye. This
makes them difficult to
find. Despite this, gold
occurs in massive
trends that which con-
stitute the second
largest concentration of
gold on earth after
South Africa. In 1962,
gold was struck outside
the town of Carlin and
ever since The Next
American Gold Rush
began.
Nevada currently con-stitutes 73% of all USgold production and
gold makes up 84% ofall value of Nevadasmineral and energyproduction per year.

Sluicingcontinued from last month...
The sluice may be maintained on the surface of unworked ground or supported on bents onthe opposite side of the cut. After the first cut the boulders are thrown onto the cleaned-upbedrock. Where cuts are run on both sides of the sluice, the boxes are supported on bentsas the ground underneath them is dug out.
At other places the boxes may be set on bedrock and the dirt may be shoveled into thehead of the sluice from short transverse cuts at the upper end of the pit. Work usually be-gins at the lower end of a deposit so that bedrock may be kept drained, and then proceedsacross the deposit by regular cuts. The length and order of the cuts will depend upon localconditions.
As heavy sands and gravel build up deposits between the riffles in the sluice, it may be
necessary to stir these up to prevent packing and the consequent override of gold parti-cles. A tined implement such as a pitchfork is often convenient for this. Larger stones thatlodge in the sluiceway may be similarly removed.
Supplying WaterThe quantity of water available will influence the scale of operations and the size of sluiceused. A minimum flow of 15 to 20 miner's inches (170 to 225 gallons per minute) is re-quired for a 12-inch-wide sluicebox with a steep grade. Smaller flows than this can beutilized by storing the water in some kind of reservoir and using the supply intermittently.
A common practice followed where the quantity of water is limited is to use a grizzly orscreen over the sluice to eliminate oversize material and thus increase the duty of the
water. Reduction in the amount of material to be treated by first running it through atrommel to wash and screen out the coarse size is another effective way to lower the wa-ter requirements.
Water usually is conducted via ditch to the sluice. However, if the ground is rich enough itmay be practicable to pump water for the sluice. The feasibility of obtaining a gravity flowshould first be investigated, as the expense of pumping may be more than the cost of along ditch, when the cost is distributed over the yardage of gravel moved. A suitablenumber of sluiceboxes or some other removal system may be used to transport the tail-ings to a dumping ground away from the working area. A tailings or settling pond may berequired to maintain downstream water quality.
Ground sluicing utilizes the cascading effect of water to break down the gravel; hence,
the requirements for water are much greater. The chief application of ground sluicing isto streambed deposits. Pipelines, flumes, or ditches would be necessary if ground sluicingwere applied to gravels higher up on banks or terraces, and the larger scale hydraulicmethods would then become more favorable. If booming is to be done, a dam and reser-voir are needed.
The dam is usually equipped with a gate mechanism that permits either automatic ormanual control and quick release of the impounded water for maximum washing effect.The water may be passed over the upper face of a gravel bank or diverted against thebottom in order to undercut and carry away the gravel as the face of the bank breaksdown. All materials are channeled toward the sluice.

The natural flow of a stream can be used by diverting the current with boards or simplywith piled boulders.
"Shears" can be constructed of 1- or 2-inch-thick boards 12 feet long nailed to pairs oftripods so that the boards slope back from the water flow at an angle of about 60 de-grees.
The tripods are built in such a way that boulders can be piled inside the base to holdthem in place. A row of these shears may be used to divert the force of the wateragainst a bank, or two rows may be used to form a flume.
The seasonal nature of stream flow in different areas must be kept in mind when planningany placer operation. State and Federal agencies can provide information on stream runofffor many of the more important streams, information which will indicate the limitations inwater supply that might be expected due to seasonal changes.
