Gilpin observer., 1917-03-29

Central City this week has enjoyed
the presence Of seven prominent bus
iness men from Chic and Kentucky
who are connected with the Gilpin-
Eureka Mines company, operating the
celebrated Eureka group of claims
on the line Of Quartz hill. The gen.
tiemen came out for the purpose of
making a thorough inspection of the
mine and mill and arrange for the
extensive campaign of development
that will be followed in increasing
the output Of the properties many
told and insure large and steady div
idends.
The company has decided to put
the shaft down at least 200 feet be-
lew the present sump, which is now
600 feet. Manager Clark has already
started work Of placing a tank at
the 6OO-foot level to catch the water
and hoist it from this point while
sinking is in progress. AS the re-
quired depth is attaired, levels will
be extended on west side of the shat
to catch the continuation Of the
large ore sheets that have produced
SO abundantly from the surface down.
The 600 and levels above. that are
now prcduoirg good grade of ore
will continue their production as the
shaft is sunk. II the shaft should
ccme into ore below the 600-foot poin
from surface, the cost of sinking
would be offset by the values in the
ore. In discussing the Eureka mine
with John Slattery, who lives in the
vicinity Of the property. the writer
was tcld that in 1865 Mr.. Slattery
was sinking the shaft with Alec. Tay-
lcr, the discoverer Of the lode, and
at depth Of so feet they took out
ore running from IL to IA ounces in
gold. Mr.. Slattery has been familiar
with the Eureka since its discovery
and says he does not know Of a more
promising proposition in the county.
He terms it just a prospect in its
present state OF development, which
in reality 1t is With a depth of only
500 feet, and considering the big
bodies of fine ore that are now being
produced by mines near the Eureka
that are being worked through the
Newhouse tunnel at a depth Of over
three times that Of the Eureka shaft
The ore bodies in the Eureka are
wide and being of good breaking
ground, make Gre fast. The values
run frcm $40 and SIS ten up to
$40 a ton and at times picture ore
has been found that contained pure
gold. But where the profits are made
in the Eureka are in the steady guam
1ity Of fair grade milling ore which
gives the tonnage. With a modern
and up-to-date mill on the ground,
the ore can be handled at a minimum
expense with high percent Of saw
ing.
N. E. Isbel, Of the firm OF Simon
son & Isbell, Of Cincinnati, mining
engineers OF established reputation,
arrived with the party Monday and
will remain at the mine several
weeks, studying the ground and lcok-
ing into the milling end. He will
make some changes in the way Of
more tables for the mill and will test
the ores to determine the advisability
of installing the flotation process. Mr.
Isbell is well pleased with the prop
osition generally from what he has
already seen. The mine and mill ma
chinery is electrically driven and the
equipment in every particular is up
todate and ample for extensive min
ing.
The officers Of the Eureka COM
pany are solid business men and
those in charge Of the mine and mill
operations are competent and thor.
