Cocos Island Treasure
Finally Found
Fabulous 200 Million Dollar Treasure Hoard
Unearthed in Cocos Island
San José

A

group of Costa Rican park rangers patrolling in
the Parque Nacional Isla del Coco after a recent
storm, have discovered one of the most amazing
treasure hoards in modern history. The treasure consists of gold and silver coins and ingots, jewellery, candlesticks and religious items, and is estimated to be
worth almost $200,000,000.
Cocos island is a small island designated as a National
Park, located in the Pacific Ocean, approximately 550
km (342 mi) from the Pacific shore of Costa Rica. It was
well-known for possibly holding various legendary treasures, but its “protected area” status had forbidden treasure hunting on it since 1978.

The President is the direct representative of the
American people ... [and is] elected by the people
and responsible to them.
- Andrew Jackson

A group of six rangers who were walking around the island to evaluate the damage done by a storm on the nesting colonies of migratory seabirds, when they noticed
that the tide had unearthed what looked like an old

bor as they were instructed, Thompson and his crew
killed the Viceroy’s men and sailed to Cocos Island,
where they buried the treasure.
Hundreds of attempts to find treasure on the island have
failed. Prussian adventurer August Gissler lived on the
island for most of the period from 1889 until 1908,
hunting the treasures with the small success of finding
six gold coins.
Since it was discovered in a National park, the totality of
the treasure is now the property of the Costa Rican government, and it should be exposed at the Museo Nacional de Costa Rica, in San José. The rangers who discovered the treasure have been promised a reward for
their role in the finding, but the amount of the reward
remains undisclosed.

Ed—The fact that this particular treasure has finally surfaced just goes to show that some of the old treasure
tales are, in fact, true. This treasure tale has been discussed for years and years with nothing to show for it,
until now. It’s still out there …. go get it!



Many treasure legends have been
associated with Cocos island for
centuries. The first claim is associated with the pirate captain Bennett Graham who allegedly buried
350 tons of gold raided from Spanish galleons on the island in the
18th century. Another pirate captain, the Portuguese Benito Bonito,
is also supposed to have buried
treasure on the island, this time in
the 19th century.
Archaeologists and historians believe, however, that the discovery is
actually linked to the best known
of the treasure legends tied to the
island: that of the treasure of Lima.
According to the legend, with the
army of José de San Martín approaching Lima in 1820, Viceroy
José de la Serna is supposed to

Penny Could Be Worth
$2 Million
Bloomberg msn.com

A

U.S. penny forged in 1792 is up for auction at
Stacks Bowers in Baltimore, with an estimated
value of $2 million. If the March 26 auction
meets expectations, the coin will have realized a 200
million percent increase in value in 223 years.
Lest you start hoarding pennies in hopes that your
great- great-great-grandchildren will net similar gains,
keep in mind that this is not your average piece of
currency. Named the “Birch Cent” after its designer,
the coin is one of the first pieces of U.S. currency ever
minted, and it's one of just seven of this particular
design that remain.

On one side of the copper coin, a young woman with
curly hair (blown back as if in Revolutionary windtunnel), sits in profile, surrounded by the words
“Liberty Parent of Science & Industry.” According to
the lot notes, the face was chosen after a conference in
the fledgling U.S. house, which decided on lady liberty—against the wishes of the U.S. Senate, which apparently lobbied for the face of George Washington,
then the sitting U.S. president.
On the reverse, a laurel wreath surrounds the words
“One Cent,” which is surrounded, in turn, by “The
United States of America” in a larger font. In case
there was any confusion about the value of the currency, there’s a helpful 1/100 underneath the wreath.

Australian Gold Prospector unearths 87-Ounce Solid Gold Nugget in Victoria

A

ustralian gold prospector Michael Brown has uncovered an astonishing 87-ounce solid gold nugget during a prospecting expedition in Inglewood, a town located in the state of Victoria, Australia.

“I’m still in absolute shock about finding a gold nugget of this magnitude! As a professional gold prospector, this
find is a monumental accomplishment in my career,” said Brown. “I’ve been using Minelab detectors for years
and the investment has more than paid off.”

“The streets of Victor, Colo., are literally paved with gold. During the boom there was
so much rich ore in the area that the low grade stuff was used to level out the streets.
In 1936 the town raised $5,000 by "mining" the yard in front of the post office.”

Diesel Says “Know Your
Batteries”

W

hy is it not OK to mix different AA batteries?
Because they all don’t produce the same voltage, the voltage a battery produces depends on
the particular chemicals inside, regardless of the size.
Alkaline batteries all produce 1.523 volts, ni-cads produce 1.2 volts, lead-asides produce 2.2, and typical consumer lithium batteries 3.7 volts. Lots of electronic devices are not all that dependant on voltage, so they can
handle either alkaline or ni-cads, for instance. And they
would not be bothered if you mixed battery types.
But the batteries themselves wouldn’t like it. Batteries
are like pumps for electrons. They can pump electrons
at various pressures, and that pressure is measured in
voltage. If you mix two different types of batteries, the
higher pressure one can force the other one to work
backwards. And it will break it. “Broken” batteries just
usually die or leak, but sometimes they can pop or even
explode.
It’s very important that everyone remove the batteries in
your detector when you store it for ant length of time. In
the case where your batteries leak or explode, and damage your detector or worse the manufacturer will not
cover you under their warranty. But! it is of “value
for you to know” when you
buy good quality batteries
and don’t mix brands, and
there is a problem like
leakage. Duracell,
Eveready Energizer, and
Rayovac offer to repair
any damage caused by
leaking batteries. I only
buy them and never store
brands. Even though the
discount store brands offer the same performance
for a lot less money , when
you eventually have one leak in your detector you’ll be
very, very glad that you weren’t using store brand alkalines ! Diesel and Goldfinger say!“Buy American”. Top
rated by consumer reports was (Duracell Ultra Power).

Map, Compass & GPS Clinic
On Saturday, April 21, 2015 RMPTH member Rick
Mattingly will present a clinic on the use of USGS
Topo Maps, Compass and GPS Units. Knowledge of
proper use of these items are critical to keeping
yourself located in the wild. This knowledge is also
extremely useful in completing research to find that
hidden mine, ghost town, etc. that we are all looking
for.
Please join Rick at the Allnutt Family Center in Fort
Collins, 650 W. Drake Road, from 9:00am to 12:00pm
for this clinic. The meeting room is located at the
south end of the Allnutt building nearest Drake Road.
If you have any of the items mentioned—USGS Topo
Map, Compass or GPS Unit—please bring them.
A donation of $1 will be collected at the door to pay
for room rental. Now that’s cheap learnin’!

Manhattan: Poudre
Canyon's Ghost Town
By Kenneth Jessen
Correspondent

T

he once busy town of Manhattan, located approximately 45 miles west of Fort Collins, has
vanished. Only a lush meadow, a few grave
markers and some bits of wood and glass are all
that mark the site.
The story of Manhattan began in 1886, when a number of prominent Fort Collins citizens put together an organization
to systematically search for precious metals in the hills west of
town. The group hired three experienced prospectors. In September,
these men reported finding gold ore
on the divide between Seven Mile
and Elkhorn creeks. The prospectors
boasted that gold could be panned
from almost any piece of crushed
rock. This immediately caused a
gold rush, and in the process, over
300 claims were filed.

than 40 structures.
In a mine explosion at the Black Hawk tunnel in
1892, two Manhattan miners were killed. A cemetery
was established, and they were buried north of the
present day road through the town site. It is possible
that others who died in Manhattan were also buried
in the cemetery.
Even as recently as 1970, the cemetery was used for
burials. A local character named "Rattlesnake Jack"
Brinkhoff let his family know that he too wanted to be
buried there, and when he died, his remains joined
the others.
Manhattan had a one-room schoolhouse. At first, the
school year lasted only four months,

Prospectors started a town and
gave it the unlikely name of Manhattan. It had a hotel, stores a post
office and even a newspaper called
the Manhattan Prospector. This
frontier newspaper
lasted less than a year.
The saloon, the Ace of Clubs, was
located at the corner of the town's
two main streets, Chestnut and
Manhattan. The Ace of Clubs had a
central two-story portion with three
shed-like structures attached to its sides. Even for a
Colorado mining town, the structure had an odd and
unique appearance.
Population estimates for Manhattan vary considerably, with some placing it at well over 1,000. A more
realistic figure for Manhattan's population is 100 to
200. Photographs show that the town did have more

but was later expanded to six months. The school included eight grades. On cold days, the younger children got first choice in seating near the stove. After
the population of Manhattan began to decline, the
school building was moved to Elkhorn.

(Continued from page 8)

A number of companies sold stock in the mines at
Manhattan. Among these was the French Creek Mining & Milling Co. Another was the Robertson Gold
Mining Co. with a Fort Collins druggist A. W. Scott as
its president. The Missouri Mining & Milling Co. had
three mines in the area. Prominent Fort Collins residents Abner Loomis and Frank Stover ran the
Democratic Mining Co.
In 1888, Fort Collins businessmen financed construction of a mill, and it was built on Seven Mile Creek. It
never operated properly and was eventually dismantled. The Zimmerman brothers built a five-stamp mill
and reduction works at a placed called Poudre City
along the Poudre River about 3 miles above Rustic.
This mill crushed a lot of ore, and the concentrate
was shipped to St. Louis for refining. The results were
so poor, the mill was abandoned.
In 1890, Fort Collins butcher shop owner Benjamin
Burnett proudly displayed ore from the district. Burnett owned the general store in Manhattan and was
involved with the mining towns of Teller City and Lulu
City.
Some of the mining properties had imaginative names
such as the Laugh-a-Lot, the Bacon, the Bullfrog,
Wedding Bells, Honeymoon, the Joker, Evening Star
and Tidal Wave.
F.C. Goodell was born in Manhattan and tells of a trip
that he took when he was 12 years old. He drove one
of two wagons loaded with ore from Manhattan to
Denver to be milled.
The mine's owner drove the other wagon. When the
owner received payment for the gold content, he figured he had been working his mine for a dollar a day.
As late as 1898, mines in the area were being patented, but Manhattan was all but abandoned. The
post office was closed and moved to Elkhorn. Some of
the buildings were moved to other locations. Those
cabins that remained were burned by the Forest Service during the 1930s.
At this point, it might be well to include some comments by Ansel Watrous in his "History of Larimer
County" on mining in this region. He said that although thousands of dollars and many years were
spent prospecting in the hills of Larimer County, the
returns in dollars and cents bear no comparison to
the cost. Watrous points out that almost every square
foot of the mountains from the southern to the northern boundaries of the county, from the foothills to the
summit of the Medicine Bow Range have been explored looking for precious metals. As of 1911 when
his book was published, not a single profitable mine
had ever been opened and worked.

see a mark that reads
12KGF, the item is gold filled.

Every business has its own language. Here are important
jewelry terms you need to know.

GOLD ELECTROPLATE consists of a very thin layer of
gold, at least 10K, over a base metal. Methods of applying the gold vary. Electroplate is less durable than gold
filled and gold overlay.

KARATS are a measure of gold’s fine-ness. PURE gold is
24 karats. it’s the snuff of which the gold bars in Fort
Knox are made. Gold coins, such as American Eagles,
are also 24K gold. Pure, 24K gold is too soft to be used
for jewelry.
SOLID gold is an item made of at least 10K gold that is
solid through and through, rather than hollow.
BASE METALS like copper, zinc, silver, and nickel are
mixed with gold to make an alloy are enough to use for
jewelry.
18-KARAT gold is used for jewelry most often in Europe.
It’s 18 parts gold to 6 parts base metal.
14-KARAT gold is 14 parts gold and 10 parts base
metal. Most of the jewelry you find in U.S. stores is 14K
gold.
10-KARAT gold is commonly used for men’s rings and
children’s jewelry. Be-cause it’s 10 parts gold and 14
parts base metal, it’s harder and more damage resis-tant

VERMEIL is a thin layer of gold over sterling silver. Museum catalogs offer a lot of vermeil (and gold-filled) jewelry
PINK WHITE, YELLOW & GREEN
Gold can be 10K, 14K, or 18K. The colors have nothing
to do with the fineness of the gold. They’re related to the
types and proportions of base metals used. Copper and
silver make gold look pink. White gold requires nickel in
the allow. Silver cadmium, and copper create green.
Different finishes can give gold jewelry different looks.
The DIAMOND-CUT finish is probably the most heavily
promoted. Tiny cuts in the surface - like facets on diamonds - give a little gold a lot of sparkle. HAMMERED
gold has evenly spaced indentations. Roses and scrolls,
such as you might find in a traditionally styled bangle
bracelet, are often ETCHED. A HIGH-POLISH finish
scratches easily but, over time, the scratches can give the
piece a rich patina. A MATTE finish has a dull, soft look.

Lot Of Gold
The following amazing fact is quoted
from a recent article in the
"International California Mining Journal."
"Major mining companies in the Black
Hills (South Dakota) produced
527,400 ounces of gold last year
(1997), state reports show. That's
down from 558,896 ounces the previous year (1996)."
Now that's a lot of gold!

pick up toilet bowl cleaner (I use Lime Away) and just

No Mercury
Tom Ashworth shares his technique for
extracting gold from black sand
without mercury.
By Tom Ashworth

T

here have been many questions on here about
how to get gold out of black sand. I thought I
would post a method that I use on cleaning up on
my 6" dredge. I clean up the top of my sluice box everyday and the rest of the sluice box when it is needed. One
problem I see with a lot of new miners is they clean up
too often and this takes away from the time the could be
dredging and finding more gold. If you
have the sluice on your dredge set up
so that the gravel is not getting too full
between the rifles and not running so
fast that it sweeps the rifles, then once
a day clean up is all you should need
on most store bought dredges. The
perfect set up for the sluice is so you
have about one quarter inch of carpet
showing between the gravel of the middle riffle of the sluice and the one below it. Now dredge all day.
After dredging all day I empty my
dredge into a large wash tub. I then
screen those concentrates using a 20
mesh screen into a 5 gallon bucket. I then pan the concentrates that did not go through the 20 mesh screen
while down at the river (looking for nuggets of course).
Any gold found in the concentrates that were too large to
fit through the 20 mesh screen, I put in a vial. I then put
a shovel sluice (a Keene or Le Trap sluice works well)
inside the dredge sluice so that the shovel sluice is close
to the header box or jet flare. I use a modified Keene A52 sluice. It has some NoTrax matting glued in the top to
catch fine gold. I then start the engine on the dredge at
idle so the water runs down the shovel sluice. I adjust
the engine so that the water flow is swift enough to wash
out light sand and still save all of the black sand and
gold. The output of the shovel sluice goes back into the
dredge sluice and there are still several riffles in the
dredge sluice that will catch any flour gold that happens
to escape (this will remain until the next time I dredge). I
then scoop the concentrates that I screened into the
shovel sluice. When all concentrates are run, I then
empty the shovel sluice into a 5 gallon bucket.
To do the final clean-up I use a panning wheel and a microsluice. You can also pan down to get to the last of the
impurities. These impurities usually consist of a small
amount of black sand, a few iron rocks, and pieces of
lead.

There are many ways to go about doing this final
cleanup. Personally, in general cleanup I like to stay
away from the use of mercury, as there is a faster way
without it. I also like to stay away from the use of nitric
acid because its usually not needed either. There are
times when the use of mercury and nitric acid can help
speed thing up. Usually though, I can do the final
cleanup without them.
Here's one quick procedure to do the final cleanup;
(1) Dry out the gold by pouring it into a metal pan and
heating it over a stove outside. Don't get it so hot that
any pieces of lead which are still with the gold will melt.
Heat it up just hot enough to dry it out. It is a good idea
to stay upwind anytime you put gold in a pan and heat it
up. Mercury attaches itself to gold in different amounts.
Often it's there but you can't see it. When heating the
gold to certain temperature, the mercury vaporizes off.
These vapors are
very dangerous. So
it is good practice
to heat your gold
outside and downwind of you, even
when heating it up
just enough to dry
it out. Also, the pan
you use for heating
up gold during
cleanup should be
used only to cleanup, not for cooking.
(2) Once the gold is dry, bring it inside, out of the wind,
and pour it onto a piece of clean paper. You can now
pick out the larger impurities from the gold with tweezers.
(3) Now a magnet can be used to extract most of the remaining black sands for you gold. I use a Keene Gold
Magnet.
(4) By lightly blowing over the gold, you can finish extracting the rest of the impurities. If you can locate a very
fine screen you can use it to separate the smaller pieces
of gold and impurities for the larger ones just after drying it out and this speeds the process up a bit.
(5) Put you gold back in the metal pan, take it outside
and heat it up, hotter this time, in order to vaporize any
further mercury for the gold. This will bring your gold
back to the basic deep rich beauty which we love.
(6) Now you can put it in a bottle. If you want to sell it
keep it dry, but if it is for show put water in the bottle to
keep it beautiful.

rency minted.
This isn’t the first time the coin has come up for sale. It was considered a collector’s item as early as 1882, when it was offered as part of
the collection of Charles I. Bushnell Esq., a collector of Americana. It
popped up eight years later, in 1890, and again in 1921. Four years
after that, in 1925, it was advertised for sale for $1,000
(approximately $13,500 today, adjusted for inflation). It last appeared
in 1975, when it was purchased by the current consignor, who is selling it to benefit the Henry P. Kendall Foundation, which works to nurture sustainable food systems in New England.
The auction has a total of 560 lots. Aside from the Birch Cent, other
standouts include a silver cent, also from 1792, which is expected to
sell for around $400,000, and an (ill- fated) Confederate States of
America half-dollar, which also features lady liberty—this one seated
and endowed with dubious physical proportions—which is expected
to sell for more than $600,000.
In total, the collection is expected to net from $5 million to $10 million. Other standouts include a silver cent, also from 1792, which is
expected to sell for around $400,000 The auction comes at a time
when the coin market is at its highest point ever. In 2014, an estimated $536 million of rare coins sold at auction, and the U.S. market
rose to an estimated $5 billion, according to the Professional Numismatists Guild. A representative from Stacks auction house says that a
range of collectors will be vying for the Birch cent: Americana collectors, coin collectors, and investors hoping to capitalize on the coin’s
rarity. Although the auction house won’t comment on specific bidders, here’s reason to believe that the coin will easily surpass the $2
million estimate—a Birch coin sold for a stunning $2,585,000 in
January.

UPS Aircraft Maintenance
Remember it takes a college degree to fly a plane, but only
a high school diploma to fix one.
After every flight, UPS pilots fill out a form, called a gripe
sheet, which tells mechanics about problems with the
aircraft. The mechanics correct the problems, document
their repairs on the form, and then pilots review the gripe
sheets before the next flight.
Never let it be said that ground crews lack a sense of humor. Here are some actual maintenance complaints submitted by UPS pilots (marked with a P) and the solutions
recorded (marked with an S) by maintenance engineers.
