The following interesting article
on the life of copper mines is taken
from Iron Ore:
The life of mining property nat
urally depends upon its Dimensions
with reference to the thickness of
the vein and the speed given the
work of mining. In Cornwall, where
many of the greatest miners upon
earth sprang from, and whose people
are found in prominent positions
wherever mining is prosecuted, we
find mines of copper, tin and iron
that have been operated for hundreds
of years, some of them closely ap-
preaching a thousand, and these
mines are still active. In the old
days the pace was slow, the great
tonnages of ore of modern times not
being possible withthemeansathand
for securing an output. 1t is proba-
BILE, also, that the markets would
not take the big volume of mineral
the growth in mining having about
kept abreast with the demand.
In our own country and region we
point with much pride to Calumet &
Hecla because of it's big accomplish

in very nearly every mining prospec-
tus that has been presented in the
past quarter of a century, editors OF

Superior organization. one can
print a very attractive story concern
ing it's record, and to find other such
lodes of mineral-hearing material
has been the object of mllllons OF
searchers.
And with the big annual rock
and copper tonnage secured by Cal
umet & Hecla it has been active for
nearly forty years, employing thous-
ands of men and being always an
aggressive concern in it's several
prominent departments.
The Quincy is another OF the oio
mines. it having been active for more
than fifty years. These old roper
ties are still looking well UNDER
ground and will be good for many
years to come, certainly as iong as
hey have already been operating.
There are many old timers IN II
history of Lake Superior copper llelo

as they did fifty years ago, but the

of a profit being secured through
their working. The Oldest are stlll

Superior region, in the old mines, has
seen a depth, vertically on some
of the lodes of nearly a mile.
In the iron districts of Michigan
we have attained a depth OF 1,SOt
feet vertically and are mining large
bodies of high grade ore at this
distance from the surface.
In the case of the Iron ore fields
of this country the ore lies in trough'
