much pleased with the manner in
which the development of the mine has
been conducted during his absence of
several months in Houghton, Mich.
The plan of exploration that has been
followed out at the Superior and Bos-
ton mine has included as its main
features shaft sinking, prosecuting and
drifting The churn drill method of
prospection that is being used largely
i'm the Miami district has not been re-
sorted to by the various companies
operating near Copper Hill for the
reason that the ores in that district,
so far as Is known, are high grade
and occur in ridges, thus presenting
an entirely different mining PROPOSE
ton from the big masses of low grade
sulphide ores that have given Miami
district its reputation as a mineraliz-
ed area. Churn drill work i'm a country
having its copper deposits in lodges is
not as a rule practicable. In the Cop
per Hill district development by means
of shafts and lateral workings there
from, has given excellent results to
those who have adhered to it and the
most notable instance of such success
in development has been afforded by
the operations on the property of the
Superior and Boston Copper company.
Concerning the work at the Superior
and Boston. President Rice made the
following statement yesterday:
For the past six months our eff
forts have been directed toward plac-
ing the Superior and Boston i'm posi-
ton to produce ore and at the same
time we have not, / think, allowed our
zeal in. this direction to blind us TO
the necessity. Of doing our development
work thoroughly and with q view to
the future Having proven i'm the
Great Eastern mine the existence of
large body of high grade ore, two
things were necessary to do, namely,
to sink large shaft at the most ad-,
vantageous point possible for the pur-
pose of mining this ore economically
as well as FOR the purpose of explor-
ing the old Dominion vein, and Sec
ond to properly equip this shaft with
a permanent surface plant, and to this
end the McGaw-a large three com
partment shaft-was started and has
now reached the coo foot level and
during the summer a surface plant
and equipment capable of high duty
has been installed and for a month or
more, has been i'm successful opera
ton. 1t is efficient and entirely sat
isfactory i'm every particular and our
construction work is now practically
finished. leaving the management free
now to prosecute underground work
vigorously. ore bins will be erected
at the McGaw shaft, a new side track
laid, and prosecuting to the Great
Eastern ore body started, and at the
same time drifting east from the Wine
i'm the Great Eastern mine at the 600
level will also go forward on the vein
and ore will again be coming to the
surface through the McGaw shaft.
The driving of this drift will serve TO
make an earlier connection with the
proposed crosscut. and will greatly ia
cilitate stopping and an increased pro-
duction. and at the same time ex-
plore the ore body farther east than
was done in the upper levels, and
there is every evidence that this ore
body will take on larger proportions
and reveal higher grade of ore and
more of it than in the levels above,
with the possibility of another tense of
ore farther east, which is the opinion
expressed by several prominent en-
gineers who have examined the Sup
erior and Boston recently. In the
Gardner, the work has been purely of
an exploratory nature. AS you know,
the early development work at this
south end of the property consisted of
driving the Black Oxide tunnel along
the vein and having proven the exis-
tence of good ore body In the tun-
mel, the Gardner shaft was started and
sunk to a depth of $50 feet below the |
tunnel level. from the bottom of which |
drifting and prosecuting has been in
progress for some months. In the |
west drift, which is being driven rap
idly toward the ore body, the vein
was recently crosscut and found to be
over 30 feet wide, with the ledge mat
Ter very rich i'm manganese and iron
md showing some slight copper stains.
With lead as persistent and strong
rs this Buckeye vein is. with a known
,re body proven 500 feet above, and
With conditions as promising as they
ire today in this west country. we look
or the development of good ore body
m this level and expect the Gardner
o become n producer"
Asked regarding the financial status
If the company, Mr.. Rice said:
We did our financing last spring,
md have large treasury balance.
With our heavy construction account
closed. our property entire
y paid for and no Indebtedness"
