The diamond drill. (Crystal Falls, Iron County, Mich.) 1887-1996, 1907-08-31
THE LARGEST SHAFT
IN THIS DISTRICT
IS THE ONE NOW BEING SUNK At
THE ToBIN NINE.
BRISTOL FORGING TO FRONT
Mine is Looking Better in Every Way
Than Il Has And Gives Rich Promise
For Future.

shaft was commenced Monday morning
and the event was one OF more than
passing notice on. at the big property.
Captain Pengilly. whose good work at
the property has won much applause
for him. drilled and blasted the first
mole while William Harvey turned the
frst shovel OF dirt
The shaft will be the largest in the
Crystal Falls district and will measure
sx26 inside Of timbers giving room
for four compartments. The shaft will
be sunk to deptn Of 500 feet vertical
In order to reach the shaft underground
tunnel 300 feet long rock in must be
run
The country rock which the shaft is
supposed 10 90 down In is states and
the operators are figuring on this kind
of ground for the entire distance
However. no one would be surprised TO
meet with jasper out there as the
formation in and about the old Co
lumbia is very wide and persistent.
II is proposed to attack the shaft
from the bottom and the top and hustle
the work through as fast as possible.
THE BRISTOL
This property is pursuing the even
tenor Of it's way. making no hurrah but
saving wood all the time and it is
quite certain that ths big output OF
last year will be exceeded this year.
The operators have been stripping
from the north side Of the pit for the
past three years but this work is now
over with all Of the ore having been
uncovered. Several years ago when
Ferdinand Schlesinger stripped the
Bristol deposit the ore that WAS left
uncovered WAS considered worthless
and il was not thought possible at that
time that 80 low grade ore would
ever be wanted. The time came, how
ever and much sooner than expected.
Underground the Bristol il looking
better than il ever did The west end
of the mine has always been an
enigma. In the upper workings there
was long. continuous deposit Of a
fairly good grade of stuff The entire
west end cut ont with depth and the
ore that has been worked for the past
four years came entirely from the por-
tion of the mine under the open pit
With the last lift the ore 10 the west
was again encountered and It is good
ore.
II IL probable that the Bristol will
have new shaft II the present coudi
tions continue az the present shaft is
located poorly for handling the product
and is too small OF dimension 10 allow
handling it with ease
Low GRADE ORES GOING
II is surprising to one who looks
back ten years and contemplates the
grade of ores that were required then
and the stun that is being shipped
now. Ten years ago no ore with less
than go per cent OF iron wAs in the
running and ore that yielded but 90 or
"a per cent was put ON the rock dump.
Today there are mines whose output is
not guaranteed above 80 per cent and
plenty of ore is being shipped that does
not yield better in iron These are not
OF the high silicious class either but
ores Of so-called high grade.
This condition is Indicative Of the
great change that has come about in
the iron business ana accounts for
some Of the big tonnage that in being
sent ont these days. il being necessary
10 ship much larger tonnage of ore
20 yield the same amount OF iron as the
ores of ten years ago did
