Gilpin observer., 1911-09-28
REPORT OF THE
GEOLOGICAL SURVEY.


by the U. s. Geological Survey as tc
the mineral output Of Colorado fol
the year 1910 is appended below. A
perusal OF same will show some
startling facts, as an instance Clear
Creek county Is credited with a pro
duction Of 81, ,029, ,26O, while old Gilpin
is put down as having produced but
$S52,695.
The government officials in making
this statement evidently must have
been off their trolly, as it Is self
evident that Gilpin county produced
at least 100000 more than 1t is
credited with.
The mine product of this county
passing through the deep tunnel
working to the South Clear Creek
side, has evidently been credited to
Clear Creek county, as the produc-
tion for the years 1908 and 1909 will
show.
The government credited Gilpin
county for the year 1908, a total Of
81 ,2S1, ,537, and for the year 1909.
e1.O70,222, while this latest report
shows shortage Of $217.527 for the
year 1910, which amount has been
unjustly added to Clear Creeks pro-
duction.
From what source has Clear Creek
county gained in its total output? In
1909, their total mineral production
was $989,473, while the year 1910
shows gain Of $39,7S7. .et
While not wishing to detract from
the glory that Clear Creek county
may have in its increased production.
and old Gilpin wishes it were double,
still, it should not be made at the
expense Of this county.
The total value Of the mine output
Of gold, silver, copper. lead and zinc
in Colorado in 1910, according to
Charles w. Henderson, of the United
States Geological Survey, was $685.
673,879, against 33,907,140 in 1909,
a decrease In value for 1910 of $685.
c61.
The production Of gold showed a
decrease OF 71,705.20 fine ounces and
OF $1.4S2,27S in value; the output Of
silver, decrease Of 393.035 ounces
and Of $34.1S6 in value: the produc-
tion Of copper, decrease of 1885,, ,511
pounds and Of $685. ,305 in value. The
output Of lead, however. showed an
increase Of 3,903.4s3 pounds and of
s243.921 in value; and the production
Of zinc Figured as spelter), a notable
increase Of 25.s79,3sS pounds and of
$1,397,4S in value.
Copper production was reported
from 90 counties in Colorado in 1910.
and Of these Lake, San Juan, Ouray.
Clear Creek, San Miguel, Gilpin, Hins
dale, Chaffee, and Eagle counties. in
the order named, were the most i'm
portant producers, Lake county alone
furnishing 1876 per cent of the total
output, San Juan county 14.5 per
cent, and the Q counties combined
SO per cent. Copper mining in Colo
RADIO is Of secondary Importance, COM
pared with that Of gold, silver, lead
and zinc. but is Of considerable i'm
portance in bringing the mixed ores
Of the state to a total value com.
mercially profitable.
In Colorado lead production in 1910
there were considerable increases in
output from San Miguel. San Juan,
Summit. Ouray. Chaffee, Eagle. Gun.
nison, Hinsdale and Pitkin counties,
and decreases in Lake, Clear Creek,
Mineral. Boulder, Dolores. and Gilpin
counties. Lake county ranked first.
and was followed by Pitkin, San
Juan. Mineral and San Miguel in the
order named.
The number Of deep mines produc-
ing metals In Colorado in 1910 was
$50. against 904 in 1909. The average
total recoverable value per ton OF
ore produced decreased from $l5.O7
in 1909 to 1887 in 1910.
There were 2.434.664 short tons of
crude ore from Colorado sold or
treated In 1910. an increase over the
output of 1909 Of 214.923 tons. OF
this total. 1.455,9S3 short tons went
to gold and silver mills. 464. .673 tons
went to concentrating mills. and
514.0OS tons went crude to smelters.
The amalgamating. cyaniding, and
chlorination mills OF Colorado pro.
duced less bullion in 1910 than in
1909. although large tonnage was
treated; and despite considerable
increases in tonnage Of concentrates
from concentrating mills. less silver
and copper were produced from con.
centrates. and there was only a
slight increase in gold production.
although there was material in
crease in the output OF lead and
