A DROPPING ON THE
JOHNNIE CONSOLIDATED

Johnnie. New. Jan. 15.-The big mill
on the Johnnie Consolidated is now in-
ished and the stamps, dropping. From
the starting of the engines there has
been no trouble of any kind and Mr..
Doubleday says that within ten days
from starting. the mill will take ore to
its full capacity. BY the end of two
weeks. which is the experimental period,
during which the proper mesh screens,
the proper drop of the stamps and
depth of discharge. and the proper grade
to the plates and amount of water to be
used to give the maximum capacity to
the mill and save the maximum percent
age of gold will be determined. and the
gates from the great ore bins will be
opened wide, 1t is hoped never to be
closed from one years end to the other.
Considered as a whole, the mill on the
Johnnie Consolidated is one of the finest
in the west and the writer is told that
1T is the third largest in Nevada.
The plant and equipment specifications
are as follows:
Cost of plant. 500. 900.
Construction was commenced Septem-
Der 9Th. 1907. Milling plant completed
December 27th. 1907. All records were
broken for rapid construction of a plant
of this magnitude.
Hosting plant. 40-horse power gaso-
line engine. Capacity of load. ~ tons
ore. Daily capacity. 24o tons from a
vertical depth of 1900 feet.
Milling plant proper. 16 Nilsson bat
~teries. Weight of stamps, 1900 pounds.
Each stamp drops 100 times per min
ute: 2,0S0.000 pounds of steel drops each
minute; 124, 500. 600 pounds of steel drop
each hour; 1895. 200. 900 pounds of steel
drop each day. of 1897, 500 tons. Full
milling capacity is $50 tons per day.
Power, so-horse power crude oil gaso-
line engine; Neher generator process.
saving 40 per cent on other kinds of
fuel.
Cyanide plant, 12O tons per day.
Compressor drilling plant; 100-horse
power crude oil gasoline engine: Neher
generator process. Drill capacity, -
machine drills.
Complete electric lighting system,
surface and underground.
Oil tank system. $4,000 gallons in re-
serve.
Water system. two miles four-inch
pipe to water rights. Water tank re-
serve. 10000 gallons; total water devel-
oped. loo, 900 gallons per day. The plant
as a whole is one of the most efficient
and substantial in the west. Mill is so
built that additions can be made with
comparatively small Expense, simply
machinery equipment.
The electric silver plate system for
amalgamation comprises $40 square feet,
half of which is made up of shaking
tables.
THE JOHNNIE CON PROPERTY
The company owns twelve patented
mining claims of ledge bearing prop
erty; four unpatented locations upon
which work is being done; water rights
covering six magnificent springs, devel-
oped under present management to furn-
ish twice as much water as needed for
all purposes. Water is brought by pipe
line direct to mill and has a gravity fall
of 400 feet. Not a drop of water is
pumped. The company also owns prac-
tically half the town of Johnnie. john
ME Consolidated is one of the largest
holders of proved mining ground in the
country.
In the mine workings there are now
100, 900 tons of ore ready to mill, the
same running III value from wv TO $4U
per ton. The hedges increase in size as
depth is attained and values materially
increase with every level in sinking. The
main working shaft is down 500 feet,
with all levels opened up and in ore.
The immense rich ore bodies which
yielded the great wealth taken from the
mine in early days above the 300-foot
level, have been found by Mr.. Perry, and
are being rapidly opened up on the lower
levels. These ore bodies, so far as ex-
plotted, are larger and richer than they
were above, and it is the opinion of min
ing men that millions have been added
to the value of the mine by this aluab
discovery.
The ore throughout the mine is en-
tirely free milling, indeed. this is char
acteristic of all Johnnie district ore.
There is not a drop of water in the mine
and no timbering is needed to support
mined ground. Superintendent Perry
says that after the mill has run so days
he will cut cost of mining and milling
below $3.50 per ton.
On the Crown Point-Globe, a property
endlining the Johnnie Consolidated, the
richest strike ever made in Nevada has
made a sensation. A large number OF
