OPERATING COSTS AT IaE
s. KEARSARGE VERY LOW

Tn the annual report of the Osceola
Consolidated, r. l. Agassiz, president
has the following 10 say 10 the stock
holders concerning the several
branches of the property;
Oseeola Branch.
As stated i'm the last annual report
your directors believed that the dis
continuance of operations at this
branch would be more economical
than TO continue to exhaust the min
eral resources and place copper upon
the market at little or no profit Com
sequently this branch of the mine was
closed down on March l, 1910, and
during the balance of the year alter
atlons and repairs were made which
viii permit of more economical opera
ton. though with the present low price
of copper your directors still believe
that il is undesirable TO resume opera
tons at this point.
No. 3 shaft was equipped with cleo
trlcal pumping machinery, and Nos. .
ana shafts were overhauled and the
shpways put in good condition. No.
4 rock house was remodeled, and, to-
gether with No. 6 rock house, was
equipped with electrical power for OPP
Grating the orushers. The new shops
and storage shed and oil house We're
finished ana equipped.
North Kearsarge Branch.
The plant at No. shaft is now
substantially completed and in condi-
ton 20 operate to it's full capacity
when underground openings permit.
No. shaft rock house has been re-
modelled and small changes in the
railroad spurs have been made which
win permit of more economical oper-
atoms.
The reconstruction Of No. l shaft
rock house viii probably be necessary
In order TO reduce the present high
costs
Tho loss of product from the os-
ceola branch has been offset i'm part
by increasing the output at the North
Kearsarge by the use OF the plant at
No. 4.
There has been a material falling off
in the quality Of ground in this branch
openings at the end OF the year not
being up % the average, and the cop
per contents saved were only 14.47
pounds per ton for the past year. The
decrease i'm values we believe viii be
offset i'm part for some time by the
improvements ut the mill, which are
to later
South Kearsarge Branch.
No construction work at this point
has been deemed necessary, as this
branch or your property has only life
at the most of four or five years at
the present rate Of production. The
ground Is now so thoroughly opened
mp that there is little doubt but that
the copper contents will only be
slightly less than the last years aver
age. namely. IS pounds, and even this
reduction may 5e offset by the greater /
extraction that will be obtained by re- |
construction at the mill The operat- !
ing costs arc very low. and with only |
n slight increase can probably be
maintained as an average during the
whole life Of this branch. The low
cost Of production and high copper
contents at this branch resulted last
year i'm securing a profit of over S43O,-
900. or about $3.50 per share of the |
total earnings.
Stamp Mill.
The washing apparatus of the COM
pary's stamp mill is adapted 10 the |
economical extraction Of copper from |
OsCeola amygdaloid rock. but it does !
not make a satisfactory extraction 1
from the Kearsarse amvgdaloid rock |
and FOR this reason the remodellng of |
a portion Of your mill is now under |
way The additional copper saved will /
he short time pay for the expense Of !
this remodeling, and it is hoped that /
Il win also offset for some time the |
lower copper contents. which must be /
expected at great depths I'm your mine
as well as in every other Lake SUI
