PROSPECTS:
It is estimated that Pennington County had
a minimum production through 1959 of
about 128,000 ounces of gold. Gold was
found in 1875 in the gravels of Spring
Creek, Palmer Gulch, Castle Creek, and
Rapid Creek.
Mystic claim (lots) are characterized with
the sharp bends, which provide for a
interesting diversified mining areas. The
heavy metal, gold, travels from one inner
curve to next inner curve, which is often
referred as the gold path. For example,
new gold deposits tend to settle at
gravel/sand bars or beaches in an inner
curve zone or below submerged boulders.
Theoretically the sharper a river bends, the
more gold deposits get pushed off from the
main path, which result in settling along an
inner bar or beach area. Therefore, this
claim (lots) provide for great mining
opportunities!! In addition, in the
downstream, there are two creeks entering
into the main channel, which make the
claim (lots) more attractive.
This claim is an exceptionally nice mining
property for a gold prospector who prefers
to work in shallow to medium depth of water
with an easy access. It is good for 2 to 4
inches suction dredges or portable high-
banker-dredge combinations. It is also
good for a panning, though you may have
to wear wade boots. Sluicing is another
good method you can approach in the
riffles area.
Note*: You are required to have a permit to do a dredging
or high-banking in South Dakota.
Even though this claim (lots) are excellent
for serious miners, it is a very nice quiet,
peaceful and secluded area where one
could just relax and enjoy South Dakota
nature. Definitely it is a good place where
you could take your family or love one with.
Keep in mind that it is generally very hard
to reserve a public or private campsite in
Custer State Park area during busy
seasons, such as Memorial weekend or 4th
July weekend unless you book several
months in advance. Please reserve your
campsite or hotel room very early in
advance. We recommend Flintstones
campground in Custer with good facility;
restroom, shower, utilities, and plus,
swimming pool, mini golfing for your
children. It seems like sites (RV, Tent or
cabin) are always available with shorter
notice reservation. The Flintstone
campground is located in the end of Custer
town. Every store is within walking distance.
