COLUMBUS EX. IS
WONDER OF YEAR
Ore Body Found After Four
Years Work Looks Like
Bonanza.

The strike in Columbus Extension
is proving the wonder Of the year, al
least I'm Alta mining circles. over
shadowing for the time being even the
unusual development in Columbus Con-
solidated. Assay returns received yes
terday from a general sample taken
from the ten-foot face Of sulphide ore
in the Extension tunnel showed val
ues OF % per cent copper and from
50 TO 90 ounces in silver 10 the ton. Sc
curing OF the high copper value is be-
Ieved To have been due TO some pecu-
liar chance. Manager Tony Jacobson
says. however. that there is no doubt
that the entire great body Of ore will
average not less than 10 per cent cop
per, and thar is high enough Tor all
practical purposes.
Possibilities of the find are beyond
computation, Theoretically the ore
body has half-mile of backs. II has
been encountered at the vertical depth
Of $500 feet from the surface, and on
The dip the distance 10 the surface is
about 5000 feet. IL is on the Column
bus great contact vein at its inter
section with che Flagstaff fissure
With a similar situation in the Flag
staff mine, adjoining. many millions Of
dollars of mineral wealth were taken

Tap Chamber OF Water.
Extension tunnel at 1000 feet from its
portal tapped chamber filled with
water. The miners had TO flee Tor
their lives. and for three days a Verit
able river flowed from the tunnel
After the flow had subsidized two weeks
of work were required to remove the
muck which had been left by the flood.
II was discovered then that the Column
bus big fault had been penetrated, that
the rushing water had washed away
the soft material Of which the fault is
composed. disclosing the vein of ore
as the westerly wall Of the chamber.

on the ore, which is opening so strong

something far out of the ordinary.
The Columbus Extension Mining COM

Tony Jacobson and Clarence Mccormick

carried on by levying a 1-cent assess
ment every so or 90 days Work has
been confined 10 the driving OF the
long tunnel. which in reality is a drift

Favored Ones Drop Out.
Making a mine in the Extension
ground has been such ''iong pull"

Of Jacobson and Mccormick became
tired and have dropped cut Jacob

not to exceed 80. 600 shares Of the stock

On account OF its being strictly a
tunnel project. the Extension is in po-
sitiOn for cheap mining. neither pumps
nor hosting plant being required. As
soon as the ground in ard about the
chamber SHALL have been fully caught
up. production from the new ore body

present proportions, the SHINING 0f Zoe

easy matter.
