CREEK
GOLD STRIKE
Large Body of High Grade Ore Is
Uncovered on Property.

It is asserted as a conservative
carefully considered statement, that
one of the most important mining
strikes ever made in this section of
the country is being now developed
and further proven upon the Amer
lean Eagle group of claims of the
Copper Creek company. 1t is not
only that the values in the ore are
remarkable, but the ore body itself
is unusually wide and strong.
Think of an ore body that has al
ready been proven for a width of
forty live feet, with only one wall
uncovered as yet, that for twenty
five feet Of this distance has furn-
ished twelve assays, not one Of
which gave returns of less than
three ounces of gold per ton. That
is good enough showing, taking
the poorest, and the fact is that as
says ran all the way up until twenty
four ounces to the ton was reached.
That is wonderful gold strike in
any camp in any country in the
world. Not so much because of
the values per ton, great as they
are, but because Of the unusual
width Of the vein carrying the val
ues.
The information noted comes di-
rectly from and is vouched for by
Col. Frank J. Sibley, the president
of the company, who guarded the
strike at the mine from publicity
as long as possible. He was ably
seconded in this effort by his son,
R. Roy Sibley, who is superintend-
ent Of all the work at the mine,
and who has been holding his
knowledge for weeks.
This gold bearing ore body has
been opened up with three tunnels.
The upper is about fifty feet below
the apex of the hill, is into the hill
about sixty feet, and has cross-cut
the vein for a distance Of twenty
nine feet. At this point, in addi-
tion to gold values, the entire ore
body carries an average of eight
and seven-tenths per cent copper.
The middle tunnel was driven in
about thirty-six feet below the up,
per, is in but seventy-fve feet, and
has uncovered an ore body that is
of unknown width, but which has
been proven for thirty seven feet
The copper contents Of this weir
average nine and fve-tenths pei
cent.
| There is luck in threes, and the
lower tunnel was sent in about six
ty feet below the middle tunnel
It is now into the hill 120 feet ant
at eighty feet cross-cuts were ru1
each way to catch the ore body
They have struck the south wall
but the north wall has not yet beer
located. Forty-five feet is tn
proven width of the ore at thi
point, with a sixty foot upraise t.
. connect the lower with the middl,
. tunnel, and this raise is all in ore
In the lower tunnel winze has al
; so been sunk thirty feet withou
getting out of ore on any side.
In this Wine and the last twen
: = ty-fve feet of the crosscut wa
| found the ore that returned tn
: very high gold values above men
toned, running from three to twen
ty-four ounces. The copper value
in this ledge are sufficient in ther
selves to attract attention to thi
; group In the lower camp. Tn
! least attractive ore carried five pc
cent, and the high grade forty
three per cent copper, the latter
bornite carrying from eleven t
! forty per cent iron, a most excel

l In addition nature has been kind t
: the company in depositing not NOR
than 1000 feet away from the sme]
4 ter site selected, a quarry Of lime
t stone 300 feet thick and two vein
: iron that will surely provide a
a future smelters there with ampl
f fluxing material. The vein matte
e in the lower camp is a porphry
b the gangue a rotten quartz.
