In It's richer parts the ore comes In Tho
form or oovelite, ch0lcopyrite and chal-
cocite. The vein Is distinctive and prac-
tically continuous, with the values gen.

ore is from 3 to 3hs per cent copper in

There Is enough ore In sight In the
mine to keep the new 600-ton smelter
gong steadily FOR long time to come
without bit OF further development.
An additional air compressor is being
installed at the mine. The latter is
also to be electrically equipped with
motors and other conveniences to oper-

of which are conspicuous in the or
ganization of the smelling company;
consequently, the two corporations are
very closely allied. The new plant
Will have an Initial capacity Of $50 tons
per day with the contributory arrange
ments for doubling this amount. Its
location Is just below the town Of
Bingham and about half mile up the
canyon from the reduction works Of
the Utah Copper company There are
no smelling plants in operation In the
West Mountain district at the present
time, as II has been customary to
chip everything to the valley smelters
at Murray and Bingham Junction
Hence, the construction Of the Yampa
plant is rather of a new departure for
the operators Of Bingham.
The ores viii be conveyed from the
mine to the reduction works over the
tracks OF the Bingham Copper Belt
railway and delivered to the, ore bins
at the smelter which have a combined
capacity Of holding 5000 tons.
The plant proper consists OF receiv-
ing bins for crude ore, lime, coke,
crushing and screening machinery. 1t
contains six batteries of Neilps sim
tering furnaces set over a brick bin
having a capacity for holding coo tons

The dust ilue and stack are feature
In connection with the plant worthy
of mention they consist Of 1850 feet OF
Fogh's brick fiue and steel incline
stack seven feet in diameter by 400
feet I'm length, surmounted on the top
by 80 feet OF eight foot vertical stack.
The steel used In the building of this
stack weighs about 100000 pounds,
The brick dust flue Is 10 feet high ana
is self cleaning
The ore, on entering the plant, ~
first elevated to screen with one-inch
round holes, the fine ore going INTO
double hopper bin, whence It is drawn
by suspended bucket tram to the
NELL roasters or sInterlng furnaces
The oversize, or coarse product irohl
the screen, grayitates to another SCI OF
bins. IL Is drawn into side dump cars
and taken direct to the blast furnace
The fine ore, after going through lh5
roasts of snterng, Is also conductor
to the blast furnace on the same tIaln
load together with its proper proportion
of coke and limestone. The pas, luI-
mace Is fitted with an automatic 'ha.s-
