CHEAP ELECTRICITY
HELPS COLORADO MINES
Application of Cyanide Aids In III
crcnsing Dividends OF Old
Producers.

Denver, Dec. 2G.-Thirty million dol
lars has been. taken from the metal
mines Of Colorado during the past year.
4 far larger amount has been added
to the value of the ore that remains
in the ground. The depletion of the
mineral resources Of the state through,
production in 1910 has been nsignlfi-'
cant when compared with the quantity
OF ore that has been brought within the
range of profitable production. There
is now Il notably larger number than
ever before of attractive opportunities
for new mining enterprise.
Cheaper and more reliable power has
reduced the costs OF producing ore. A
year ago the Central Colorado Power
company had In this state only one
hydro-electric generating plant; now it
has two and a total capacity of 26000
horsepower. Another installation at
Gore canon will enable the company to
increase this capacity whenever 1t is
required in the development of the min
ing industry. BY some one of the
hydro-clectric systems-those of the
Central Colorado. the Telluride, the San
Juan, the Colorado, the Northern Colo
RADIO and Il number OF smaller compa
nics--nearly every mining district in the
state is served. and the extension OF
their distributing lines during the past
year has made profitable the operation
Of mines that had lain Idle for Il long
period.
LOWER COSTS.
By lowering the costs of getting the
metals out of the ore, as well as the
costs OF getting the ore out of the
ground. mining profits have been in
creased. During the year. at Cripple
Creek. the Stratton's Independence mill
has been enlarged to a capacity OF 5000
tons a month. This mill was the first
large plant of the kind built in the
district, ana the pioneer in the applica-
tion of Jaw cyan!dation to the sulfo-
telluride ores ri Cripple Creek. Philip
Argall, the cneineri. by whom it was
designed and constructed. says that It
Is treating ore ut Il cost of $l.50 Il ton
and he predicts Il further reduction in
the cost to $1.e5 and 81. This mill is
earning dividends on the three-dollar
ore of which there is million tons on
tho dump. and IL making it profitable
to break and hoist four-dollar ore.
A similar plant at tho Portland mine
has been in successful operation for
about six months. 1t has a daily ca
pacty OF 800 tons, or 1000 tons n month.
Its crushing capacity is 1000 tons daily.
and equipment for bringing the entire
plant up to this capacity can be added
for $4,000. BY the use OF a special So
luton the Portland mill Is said to be
making a recovery Of 80 per cent of the
gold In the shines. There is 100000
Both the Portland and the STATIONS
Independence slip their concentrates to
the valley plants.
CYANIDE MILLS.
The construction Of other large cyan
ide mills in the Cripple Creek district
may. be expected to follow from the
silprpss pT fhoSp that arr, t,I,ftipfy
Z millions of dollars into the value of ore
that q year or two ago had no value
whatever. And what has been accom-
pished with the cyanide process at
Cripple Creek can be done in other
mining districts of the state. The OPP
portunities are many.
Tho completion of the new Lake mill
and improvements Mt the Wolf Tongue
mill In Boulder county have resulted
in II closer saving and higher prices,
and have stimulated the production OF
tungsten. Boulder county is the chief
source of the worlds supply of
tungsten. III San Miguel country there
has been a larger production of van
atlum, another steel-hardening metal.
At Cripple Creek the Roosevelt tun-
mel has been completed. and will grad
unlly drain the district to an additional
depth of 730 feet The cost OF the tun
mel. in round numbers. was 100000;

In Gilpin county, the Newhonsc tun-
mel has reached its final terminus.
Boulder county III 1911 should show
large production from the Up-to- Date
tunnel recently completed near Carl
bou, and from at least two of the tun-
mel enterprises Mt Eldora, Some re-
mnrkablc veins of high grade silver
ore have been opened in the Up-to-
Date.
NEW. CAMP.
Clear Greek county has larger ship
mcnts and the discovery of new
camp on Bard Creek to report. The
smcter at Golden is kept in continuous
operation The new Hudson mill at
Idaho Springs is showing gain in
efficiency that win add to the profits
of Clear Creek county mines
Park county now has pyrltlc
smerter, which was put into success
ful operation at Alma last summer
and a similar plant will be ready to
blow in at Red Mountain In Ouray
county within the next six months:
