SAN JUAN
COUNTY
FOR 1901
Wonderful Increase In Produc:
V ton of Precious Metals
for the Year.
New Producers and New En-
terprises Forging Rapidly
to the Front.
Greater Mining Calls for Ad-
ditional Mill Facilities
and Tramways.

From advance sheets of the Sill
verton Standard of today The Her
aid is enabled to give condensed
resume which appears in that en-
terprising journal, rgarding the pro-
gress OF mining in San Juan county
during the past year.
The Silverton district for 1901 has
shown all average value in conccn-
trates from shippers shipping more
than five carload lots of S62 per ton
in gold silver. copper and lead. a
total of s2,540,760.
Amalgam sent to the mints an orc
expressed to outside points amounted
to $244144.
The Kendrick smelter produced
matte of value of $150,000.
The total value of the output is
thus $2,934,904
San Juan county shipped for the
year in ore and concentrates 40.9SO
tons,
The Gold King Consolidated for
1901 shipped 10.100 ions of concen-
trates. Basing the estimate OF six
per cent dividend on $5,500,000 in
vestment, the value OF concentrates
will reach sos per ton average. While
. the most extensive improvements ev-
er made on the enterprise were made
during the past year, the largest div
idend has been paid. The American
tunnel in Bonita gulch will soon tap
the Gold King and Sampson veins
!. ut great depth, increasing the pro-
duct and necessitating additional mill
facilities.
The Silver Lake mines have pro-
duced and treated at the mill an av-
erage of 300 tons per day, besides the
crude ore shipped direct to the smell
ters. A force of from $50 to 400
hsa been employed. The Unity
tunnel will largely increase the out
put during the coming year. 1t is
calculated that the average output OF
ore will be 400 tons daily. This
amount can be greatly increased at
any time. Wonderful development
Is planned and will be pursued. The
management is employing every help
which science has given to mining
and milling. The average value of
the Silver Lake concentrates is up
s.to the value of the average of concen-
trates of the Silverton district.
% The Sunnyside mine in Eureka
gulch, one of the great gold producers
of Colorado, during the past week has
developed an ore measure which is 81
feet wide. The workings are no
where deeper than 500 feet, but All
immense tonnage has been kept up
for years. The mine and mills are
lighted by electricity The longest
tram in the country carries the ore
to the mills. The upper mill handles
80 tons and the lower so tons OF ore
daily The proportion of crude tc
concentrates is six tons to one
Large quantities of building mate
rial, a 150-horse power Corliss engine
and new machinery for mine and
mill have been received and the mill
Ing capacity will he doubled. About
$4,000 has recently been expended
in improvements. Nearly 100 mer
I'll told are employed.
The Iowa-Tiger is among the pif
ones. During last year 100000 was
expended in improvements, for new
houses, stores and powder house
,0Srom 1870 to 14O tons daily has beeI
the output, shipping two or three car'
of concentrates daily. The chic
values of the product are gold an'
lead,
The Hercules Consolidated on Sui
tan mountain extracted for the yea
$4,000 tons of crude ore of an aver
age value of $T.62 per ton, and 5.O1'
tons Of concentrates were shipped
Int tne
There are over 10000 feet Of under

2.7OO feet of work has been perform
