Houghton, Mich, April 17.-Final fig
ures OF production of refined copper by
Lake Superior mines are all in, except
for the Trimountain, and In that case the
|estimate Of 5000, 900 pounds is based on
an unofficial but direct estimate of the
company. The figures of production for
ITO, 0,S31,59S; 1901, 155,716.848; 1900, 142,-
l151,571.
These figures show gain Of practically
10 per cent for each of the two preceding
years. For 1903 the increase will be more
than is per cent, and very probably 20 per
cent. The increased production secured
in 1901 and 1902 were practically the first
increase for five years, and reflect the
increased productive capacity Of the dis
trict brought about by the opening Of
new mines, rather than any marked in
crease in the output of the older mines:
The total production Of the new mines
was a trif1e more than 100000 pounds
in 1901, and upwards Of 10000, 900 pounus
for 1902, and should be doubled during the
present year.
The output Of the Calumet s. Hecla was
practically the same In 1902 as in the pre-
ceding year, and the mine Is now pro-
ducing at practically the same rate, of
about 100000 pounds OF refined copper
monthly. The new six-stamp mill of the
Calumet. & Hecla, now going into com
mission, will not increase production, for
some time to come at least, as the Old
Calumet mill is to be rebuilt in sections
as soon as the new stamps begin duty.
Eventually this will give the property
materially increased stamping capacity.
| The Quincy output shows a slight fall
| ng off from the preceding year This was
| 1ue to the mining and stamping of rock
| If much lower average grade than former
y. In order to feed the stamps about
| 400 tons of rock are supplied to the mills
| laily, and it is impossible to furnish such
an enormous tonnage Of as high grade as
obtained formerly, when but third to
half Of this output was required. The
Quincy Is now one of the best equipped
mines upon the entire globe, and should
be able to maintain an annual output of
approximately 2o,O0o,00o pounds of refined
metal for many years to come.
| The Tannarack showed a marked de-
crease in 1902. It can no longer be de-
MED that the Tamarack is not the mine
! it once was. The three deep shafts have
all proven more or less disappointing, and
| the grade of rock stamped has been de-
clining slowly but surely for some years
until it is now below that of several of
the amygdaloid mines, even though the
bulk of the Ta1narack production is se-
cured from the great Calumet conglom-
| ,rate. a.. !: ~
The Osceola output for 1902 was but a
trife less than in the preceding year,
contrary to the general expectation OF a,
large decrease. The mines and mills are

Trimountain Is the largest producer OF
u 1902 among the new mines. While an
J. output of 100000 pounds for its first
: year of production looks large, the 1903
figures will tell much more surprising
story. The Trimountain Is one OF the
worlds best mines, and will play no small
part in the lake district in the future. =
