METAL OUTPUT OF
COLORADO IN 1910
Increased Production in Lead
and Zinc Ores Reported
by Government.
SHOWS SOME DECREASE
Falling OF; in Silver, Gold
and Copper Ores Is
Noted.

Tho total NJlNe ni Ollnt output pl Eplp,
silver, copper, lead and zinc in Colorado
IN 1910. according to Charles W. lieudcr-
son of the United States geological sur
vcy. WAS S23 .s7S.S5o. against S@S.oOi.1io
IN 1909, a decrease in value for 1910 OF
s23S,26i.
The production Of gold showed n de-
crease OF II 5o5.30 fine ounces and OF
Sl.iS2,2IS in value; tho output Of sil-
yer, "A decrease Of 1898 0S5 ounces and Of
$34,ls In value, the production Of cop.
per. decrease OF 2632. .5ll pounds and
Of 5S.205 IN value. Tho output az lead.
however. showed an increase of 3.?0S.iS
pounds and OF S2i3.92l I'm value; and the
prodnction Of zinc digured as spelterp. a
notable increase OF 25.SI9SSS pounds and
OF 81. .391.iS1 I'm value.
OF the gold output tho Cripple Creek
district produced SIi.o02.25S In 1910. or
53.I per cent of the total gold from All
sources in colorado. This WIS n decrease
OF sos .s2o from the output for 1909.
Most Of the Cripple Creek mines were
operated with reduced forces, the opera
tors prefcrring TO wait until the mines
were fully unwatered rather than main
tain normal output AT a heavy cost for
pumping The gold output Of Oursy
county decreased SslS 97s from tho heavy
output Of 1909. which was an increase NJ
81 .oI6.i27 over the yield Of 1905 In, La
Plata county the gold output incrcascd
an Increase Of $i25.i 40. The placer out
put of gold Was 1896 i6j. a decrease Of
s63 027 from the production for 1909.
Silver Falls Of.
In the production Of silver in Colorado
In 1910 Lake county ,LeSdville) made 80
per cen Of the total state yield. This
county showed decrease In output Of
i0l. .62I ounces in 1910. against an in
crease OF over 100000 ounces In 1909
There was decreased production OF sill
yer also In Piikin. San Miguel and many
other counties Increased output OF sill
ver was credited to Chaffec, La Plata
and Ouray counties IN 1910. The chief
reproducing counties in Colorado in
1910 were Lake, San Miguel, San Juan.
Mineral, Ptkin. Clear Creek and Ouray,
in the order named; these counties com
bined furnished nearly s. per cent of the
total state production.
Copper production was reported from
twenty-three counties I'm Colorado In 1910,
and OF these Lake. san Juan, Ourar.
Clear Creek. San Miguel Gilpn. Hinsdale,
Chaffee and Eagle counties in the order
named. were the most important pro-
ducers. Lake county alone furnishing 1876
per cent OF the total output, San Juan
county 1i.J per cent and the 9 counties
combined 90 per cent. Copper mining In
Colorado is OF secondary Importance COM
pared with that OF gold. silver. lead and
zine, but is OF considerable Importance in
bringing the mixed ores OF the state TO
total value commercially profitable.
In Colorado lead production In 1910
there were considerable increases In out
put from San Miguel. San Juan. Summit
ouray, Chaffec. Eagle. Gunnison. Hins-
dale and PitlIin counties and decreases
in Lake. Clear Creek. Mineral. Boulder
Dolores and Gilpin counties. Lake coun-
~ ranked first, and was followed by Pit
kin. San Juan. Mineral and San MiNuel
In the order named.
or the Colorado zinc output OF 71.0s9
64S pounds, Lake county produced I3 per
cent, with an increase in output Of IL
i30, 100 pounds. Shipments OF the newly
discovered zinc carbopatcs from Lead
viilo were relatively slight In 1910. but

both zinc and lead from this famous old
district In the future. Increased produc
tion OF zinc was also made in Eagle
San Juan. San Miguel, Mineral Clear
Creek and Park counties in 1910. The
only material decrease was in Chaffec
county. Until 1907 The zinc mining and
smelling Industries were OF slight reIa-
tive Importance i'm Colorado hut they
have been OF yearly increasing impor-
tance. and in 1910 they exceeded in value
of product those Of Iced and OF copper.
The number OF deep mines producing
metals I'm Colorado in 1910 was S56
against 904 I'm 1909. The average total
recoverable value per ton OF orc pro-
duced decreased from sl9.07 in 1909 to
si3.57 In 1910
Total Ore Tonnage.
There were aa3466l short tons of
crude ore from Colorado sold or treated in
1910. an Increase over the output OF 1909
of 2lG.923 tons. OF this total ! ij5. .9S3
short tons went 10 gold and silver mills.
iSi.s12 tons went TO concentrating mills
and u ,00S tons went crude TO smclters.
The amagaInating. cvanldinS and chor-
nation mills OF Colorado produced less
bullion in 1910 than i'm 1909. although "A
larger tonnage was treated: and despite q
considerable increase In tonnage OF con-
cTnirates from concentrating mills. less
silver and copper were produced from
concentrates and there was only a slight
Increase I'm gold production although
there WIS material Increase In tho out
put Of lcad and zinc There Was de-
creased tonnage Of orc sfncltcd ju Colo
RADIO In 1910 and decreased output OF
metal from smelling ores. The mills
-~oatcd - per cent Of the Colorado ores
and the remainder was smelted crude In
1910.
