company have been definitely an
nounced and f. w. Bradley, who is
president of that company as well as
of the Alaska Treadwell, has made
public the extent of their operations
both immediate and future
The Alaska Juneau company is to
be operated on the same plan as the
Bunker Hill & Sullivan mine in Idaho.
The men are to be Independent. live
where they please, board where they
like, and spend their money in such
manner as suits themselves. The
company will maintain no boarding
houses nor living apartments for its
crews.
No Company Business.
There will be no company stores
nor places of amusement. The men
are to be encouraged in their indie
pendence to the end that they become
identified with the community's in
terests and become social unit Of the
community rather than a mere cog III
the wheel Of one industry.
The first unit of the great reduction
plant will be in operation during the
month of December of this year and
the increase of the plant will continue,
keeping pace with the mine develop
ment until 1t reaches its maximum
capacity of II 900 tons daily.
The Alaska Juneau adjoins both the
Perseverance and the Elmer and has
been under development and opera
ton for several years, working from
with small MILL The future method
is to work on a large and economic
scale, such as that adopted by the
Alaska -Gastineau Mining company,
which is developing the Perseverance,
The rock house is already practice
ally completed and the tearing away
Of debris for mill foundations is pro-
crossing rapidly. The entire reduction
four units, of four 150-stamp mills.
Each of these stamp mills will have
an auxiliary of Is Chilean mills, and
will use 80 roughing tables and As
concentrating tables.
Great Ore Reserves-Big Mill Capacity
Each unit will have capacity of
1000 tons of ore daily, or 100000 tons
during each years run. When the
plant reaches its full capacity it will
mill $4,000 tons of ore daily, or 4000,-
600 tons each year.
The ore shoots on the Alaska jun
eau property are 500 feet in width and
are estimated to contain 2d1,00O,0OO
tons of ore above the present tunnel
levels.
The main tunnel of the mine is
above sea level 400 feet at it's portal
and is 600 feet long, rising to 40
feet at it's inner terminal. At this
point raise of 500 feet Is now being
made that will penetrate Silver Bow
basin The main tunnel was complet-
ed a few weeks ago and the raise Is
now under way and progressing at
the rate of to 10 feet each day. From
the portal of the tunnel a traffic line
is provided along the mountain side
for the transportation of both ore and
water
A small gasoline engine Will draw
the ore cars for the present and AKA
flume parallels the rails, carrying wa
ter for the mills. There are two short
tunnels and one tunnel, 2250 feet in
length pierces Mount Roberts.
How the Orc Is Handled.
On the bay side the line follows
along the mountain side to mill site,
q part of which is within the city lin
it's of Juneau. The ore commences
the process of reduction at an eleVa-
ton of 400 feet, where 1t enters the
rock house to pass through the crush
ers. The gravity system has full
swing and the ore keeps dropping UNI
til every process used in the extract
ing of values has been completed ana
the tailings are carried into the pond
set aside in Gastineau channel.
The mills are set at an elevation OF
ITO feet, giving grade sufficient TO
carry talings for several miles Inc
company has set aside pond where
tailings will be confined and which
has capacity of 100000 tons.
Vast Water Power.
Power will be generated by hydro
electric plants. At Nugget creek
some Is miles from Juneau, the Alas
ka Treadwell company has a plant
now in use, and with the Alaska Jun
eau company shares in the ownership
of the water rights of that stream.
The entire stream with its three bas-
ms is estimated to be capable OF de-
veloping 5000 horsepower OF electrical
energy. The Alaska Treadwell Is now
using 1900 horsepower developed on
the lower basin of tho stream IL Is
the intention of this company to buiio
a dam to increase the efficiency OF It's
plant. The Alaska Juneau company
will utilize both the middle and lower
basins, constructing dams so as 10
have two reservoirs and use the water
over again after it has taken It's hrs'
plunge, and then let it pass below lof
