STREAM Of ORE
At COLUMBUS
Hanging Wall of Contact Is
Reached and 200 Tons of
Fine Ore Roll Out.

After raising for thiFty-five feet or more
through ore the hanging wall of the big
contact ledge in the western portion OF
the Columbus Consolidated company 5
Alta property has reached the hanging
wall. And here an unusual thing hap
pened. Before telling about it. the ex-
PLANTATION should be made that a raise
from the 400 level below the tunnel was
made in a rich ore-bearing fissuTe eighty
feet before il became apparent that the
contact was being entered. The ore body
buIged out, and where the foOtwall Of
the contact was found the slope was ten
sets wide. Drifting was done in both d.
rections through fine ore along the foot
wall. and finally, a day or two before
Mana ger jacobson returned from the
mine, the last square sets were being
placed on the hanging wall side. Now for
what happened:
up in one corner explained Manager
Jacobson. lit Was necessary to dislodge
a great chunk of solid ore that occupied
A place where the end of one of the tim
bers should go. This opened up hole
probably two feet deep, through which
stream of dry, black, sandlike sulphide
ore began to run. This material ran down
into the big stope, and before it was
checked through the accumulation of the
stuff under the hole not less than 2OO
tons had run out. The ore is for all the
world like the coarse stuff from con-
centratIng table, dried out This ore sam
pies 10 per cent copper and 10 ounces sill
yer per ton, with fine excess of iron over
silica, and makes an ideal shipping prod
uct. Until we have punctured the ledge
at points higher up and nave gone
through to the hanging wall side, which IS
to be done as quickly as possible. We
shall not know much about the conditions
that have produced this phenomenal II
the material was wet / should feel some
what alarmed over this condition of af-
fairs, but as the material is as dry as
q bone, feel that no damage viii result
- in
fhe vein where this fine stuff has come
from"
This same great ledge has been opened
through another raise, away back from
the one that has been pushed through to
the hanging wall, and a fine body or ore
"a exposed there. AS matter of fact,
it has now been determined that the ore
is continuous for $50 feet but how much
farther can be determined only by work.
Mr. Jacobson believes they are now OPEN
ing up the greatest body of ore that was
ever encountered in the camp of Alta
and he is making preparations to send out
2 tonnage next month that will clean up
the company's indebtedness and leave 1t
with big surplus into the bargain
In the eastern portion Of the mine,
where the big ledge that was so prOduc-
tive above was found TO have faulted on
the 100 level, prospecting has been going
on for some time, and a formation has
been struck that is identical with that
which lay next the ore on the upper
levels Water commenced to come in quite
rapidly. however, and the management
has ordered work stopped there until the
big station pump. now on the way here.
has been received and installed When
that arrives the company will be able
10 handle 1000 gallons Of water a min
ute without crowding. Then this east
drift will be pushed through. and the
expectation is that another whaling big
body Of high-grade ore will be tapped
and made available The mine is only
making about 800 gallons Cf water a
minute at the present time, but the spring
surface water problem is at hand, and
It is not deemed wise to invite trouble
by tapping the east ledge at this time
