LAKE. SUPERIOR COPPER
Last Years Output Oyerestimnted
About 2O,OOO,oOO Pounds.

HOUGHTON, MICH.-The oficiaf fig
ures of production by the Calumet q
Hecla for the fiscal year ending April 80,
show an output of about 20, ,O00. 900 pounds
less than the commonly excepted estimate
of copper produced for the calendar year.
1901. While the figures for the calendar
year will differ to some extent from those
of the fiscal year, it is evident that the
output of the mine has been oyer-esti-,
mated. 1t is apparent that the accepted
estimate of 70,O00,00o pounds production
by lake mines last year is considerably
in excess of the real output, which was
probably about $50, 900, 900 pounds only.
The Calumet & Hecla is now employ
ing much smaller force than eighteen
months ago, but is stamping a larger
quantity of rock. This rock, however, Is
not as rich in copper as the average of'a
few years ago., The maximum output of
the Calumet & Hecla was in: 1899, when
S9,610,963 pounds OF refined copper were
produced. Each of the two following
years has shown a decrease.
The Protogene Gold Mining company,
limited, has been chartered under the laws
of Ontario, by local mining men and cap
italists, to operate the Foley mines, at
Mine Center, in the Rainy lake district OF
Ontario, on the northern side of Lake Su-.
perior. These mines have been. con-
siderable producers of gold, but have suf-
fered from poor mana cement. It Is hoped
to resume operations next month and as
the mines have complete equipment, in
Guiding stamp mill, production can begin
practically as soon as the shafts are un-
watered. - 4 r., ;t+at, 60 - -... ~,
The new mill of the Champion mine is
progressing rapidly and is about the only
one in the district that is. not suffering
from, delays in the receipt Of machinery
promised for delivery many months ago.
Ia in min onfS
stamps in operation, the mine should pro-
duce about the same amount of copper as
the Quincy, The present high price of
Trimountain stock is unquestionably
made by the owners OF some 80 per cent
Of the stock, but Of the wonderful prom
ise of the mine there can be no question.
The Arcadian mine has been dismantled
to a large extent, and much of it's ma
chinery sold, the bulk going to the Tri-
ountain. Present activityi is confined to
the shafts at the southern end, which are
showing better than those opened to the
northward. 1t is the opinion of, the best
judges that Isle Royale is actually. earn
ing a profit on it's operations at present.
Development work has been stopped and
the working force pared to the bone. The
mill is treating about 1850 tons of rock
daily, and the copper secured is bly,
about IA pounds to the ton, as the! mill is
now running. 4f.. - s...E ...... -.,:.a ..-...
The Mass mine made a fine output in
May and should turn out fully 200 tons of
mass copper and mineral this month.
The recent talk regarding consolidation
of the Mass and Adventure mines seems
to have been started without good foun-
dation. The advantages of such a consol-
idation would be considerable, and it IS
not impossible that such merger may
be effected at some future time. though
the management of neither company
seems desirous of a consolidation at the
present time. ...E ~. -.-.5-G. So.
The assessment of one dollar per share
| levied by the Rhode Island will be used in
continuing the exploratory work now un-
der way at the property. There seems
little doubt that the Tecumseh has at last
| reached the copper chute making south
ward from No. 6 shaft Of the Osceola
| mine, as the Tecumseh shaft, now. about
1000 feetrdeep, has been in good ground
for several weeks. Shafts No. 5 npd 6
Of the Osceola proper are about all that
| is left of the old Osceola mine at pres
ent, the northern shafts having been
abandoned. 4 -. -, .-.....
