Operations at Mills.

At the present rate Of tonnage il is
only necessary 10 operate four of the
FIVE completed sections of the plant The
work OF completing the sixth section is
progressing slowly so that il will be fin
sbed by the time II is needed for use
about or shortly after the middle of the
year. The improvements that have been
applied to the fve completed sections
during the quarter were fully described
In the annual report.
Aside from the work in the coDcentra-
tor proper. some improvements and cX-
tensions were made during the quarter
main pumping station. StolScrs are being
applied in the power plant for the pur-
pose Of burning coal, instead of oil for
fuel, This change Will result In a sub
stantiaI reduction In the power costs.
The total amount OF orc treated for the
quarter was 30167f tons, containing an
average percentage Of extraction was
6s.s5 per cent. The quantity of con-
ccntrates produced was 1887 tons con-
tanning an average Of 2o19 per, cent cop
centratcs was 7,122,943 pounds. The ay-

earning being based on q price OF 1912
cents per pound for copper. This high
average price resulted from the fact that
our concentrate shipments were contin-
ued to the FL Paso smelter until Febru
ary IL. requiring about three weeks for
transportation there. and the consequent
metal at tho seaboard gave US the ad-
vantage of the recent rapidly rising cop
per metal market on practically the en-
tire quarters production The average
all charges was 5s07 cents. The I'M

Mill Extraction.
The, mill extractions have shown a. cor
respobdingly gradual Improvement. For
the month OF March tho extraction was
69.64 per cent A substantial part Of the
reduction in the per pound cost of pro-
duction came through the discontinuance
OF shipments or concentrates to El Paso
in the month OF February. Since, the
middle OF February all concentrates have
oeen delivered to the American Smelling
&, Refining company's new plant at TJay-
den, At the time OF writing this report
they show further decrease In produc-
tion costs, and it is estimated that the
cost per pound for that month will be
about 2.35 cents.
Ono furnace OF the American Smelling
& Refining company's plant at HAYDEN
was started in operation about Nav /
and the plant IL being rapidly brought
into full commission.
