MILLING CAPACITY Of MORNING NINE TO
INCREASE FROM 1900 TO 1000 TONS DAILY
FEDERAL COMPANY WILL USE MAMMOTH MuLLAN
MiNE-FLoTATioN PLANT BEING ADDED
CHANGES TO lNcRE AsE THE CAPACITY.

By the first of February the Morn
ing mine at Mullan, owned by the
Federal Mining & Smelling company,
will have the largest milling capacity
with the possible exception of the
Bunker Hill & Sullivan, of any mine
in the Occur d'Alene district. This
will be accomplished by the changes
and additions now being made to the
Mammoth mill, in this city, owned by
the Federal, which will be utilized by
the Morning just as soon as these al
terations are completed, which will be
in about two months. The Mammoth
mill was built by the Mammoth Min
ing company and passed to the Fed
eral company when it acquired and
consolidated the Mammoth and STAN
dard mines. The Mammoth mill and
the Standard, situated near by, were
then for years used to treat the ores
of the consolidated property and un-
til the ore reserves diminished to a
point which enabled the Standard mill
to handle the output alone. Subse-
quently the Stewart Mining company
leased the Mammoth mill from the
Federal and used it until the COM
pany suspended operations. This was
about a year ago A few months lat
er the mill was leased by the Hecla
Mining company to supplement the
output of its mill at Gem This lease
will expire on December Is, when the
addition to the Hecla mill will be COM
pleted.
Federal Again Requires the Mill.
The fact that the Federal company
now finds it necessary to provide ad-
ditional milling capacity does not
bear out the oft repeated assertions
respecting the condition of the COM
pany's mines which emanate from a
certain publication consecrated to the
cause of disseminating the truth about
mining in the northwest. The truth
is that the great Morning milling
plant with a capacity of 1900 tons per
day is unequal to the task of reducing
the tremendous tonnage that is now
available in the Morning mine, con-
dition that has confronted the Federal
management with the necessity of
either providing additional milling IA
cilities or sacrifice the unusual ad-
vantages offered by the high prices of
metals Whatever may be the short
comings of the Federal management,
overlooking opportunities to increase
the revenues of the company is not
one Of them. The Mammoth mill is,
therefore, to be used in conjunction
with the Morning mill, which will
bring the total milling capacity up to
begun on an addition to the MAN.
moth mill which will house flotation
plant similar to that at the Morning
Additions will be made to the concen-
trating machinery in the mill, old
equipment will be rearranged, and in
effect the plant will be rebuilt on lines
that will adapt it to treatment OF the
Morning ores. Zinc has come to be
quite an important factor at the Nor
ming, and the remodelled plant will
provide for recovering this along with
the lead. The present capacity of the
Mammoth mill is 450 tons per day and
this will be increased to 500 tons
through the changes and additions
now being made and which are ex-
pected to be completed by the first of
February. Besides the changes In the
Mammoth mill, a new sorting plant is
being built at the mine to meet the re-
quirements of increased tonnage.
Great Ore Bodies Developed.
The Morning mine is developed to
depth of 1000 feet below the main
working tunnel, and on every level
there are large ore reserves. But the
ore is not limited to the lower levels.
A drift west from the main tunnel,
which is designated as the 800 level,
has exposed a great body of excellent
ore. In fact, the amount of ore now
in sight at the Morning gives 1t rank
among the worlds greatest lead mines.
In extent and quality the ore on the
lowest level is practically the same as
found in the levels above, and from
this, together with results of deep de-
velopment of other mines of the dis
trict, it may reasonably be assumed
that the same conditions will prevail
when another 1000 feet of depth is
added to the development Of the mine.
