IMPORTANT STRIKE
IN AMERICAN FLAG
Park City Must Include One
More Big Producer Upon
Its List.
HIGH-GRADE VEIN
EXTENDS TO DEPTH
Recent Results Have Doubled
Value of This Well-KnOwn
Property.

y discovery OF great Importance was
made Friday morning in the property in
Park City OF the American Flag COM
pany, when the crosscut on the 400 level
broke into a vein of splendid ore. When
seen yesterday afternoon by The Tribune
in regard to lhls new find. President and
General Manager George II Rathman
was unwilling TO discuss details until
more development work had been done
and thorough samplLng OF the strike
made. but from what can be learned.
the American Flag management has
greatly extended the value Of the mine
by this work and 1t has demonstrated be-
yond any doubt that this is one more
big producer for the camp.
To better appreciate the Importance OF
this new disclosure it Will be timely 10
give a little history. The property first
WAS developed by means of a tunpel, and
from low grade the ore soon opened into
first class sort of shipping rock, bring
Ing in a generous income In the early
days on being followed for some distance.
After sinking n winzc $50 feet on this
rich ore and drifting for some distance
at that depth. the company began the
main SHAFT, reaching down TO the elev-
cnth level without delay. Since this
early work. the management has devel-
oDed Very large tonnage OF milling ore
on the various levels in what Is called
the main vein, and this milling ore still
is awaiting proper disposition. Al the
same time much strictly shipping grade
ore was developed and shipped at a
splendid profit. but the ore has not been
as uniformly rich as IL was on the tun-
mel and winzc levels.
Several weeks ago the mine was visited
by Fred w. Croslcy. the mining engineer
who made an expert examination, and
he raised the question as to whether or
not any OF the veins developed by the
shaft were the same as the rich vein
FIRST opened by the tunnel Mr. Crosley
was OF the opinion that the rich vein
had not been discovered after the winZe
work. unless, perhaps, a new vein re-
Gently opened on the 100 level was the
same, He recommended. therefore, that
a crosscut be driven on the fourth level
and results arc exactly as he had antlci-
pated. The rich vein was struck within
il would be found. Inasmuch as the
American Flag is opened to the 100
level, 10 which depth 1t is entirely free
from water and in view OF the same
certain that there Is all OF 100 feet Of
stopping ground Immediately available
while the company has a half-mile of the
vein along It's strike Some very sgnid
cant developments arc logical from the
future work along this avenue. When
seen yesterday by The Tribune. Mr..
Croslcy said:
THE discovery doubles the value Of the
American Flag mine. for ii demonstrates
that the vein which gave the highest
values on the more shallow workings
mas not Dccn given any ucNeIOnmtnt
whatever from the shaft. I have never
felt more positive about any property
making good than / have in regard to
the American Flag"
Mr. Crosley's report, which was recent
ly submitted, in part follows:
The SHAFT is 1870 feet deep. with sta
tions and levels at 100, 500 500. 700. 500
300, $40 and 1910 feet from the top, or
collar, and known as the fourth. tifth,
sixth. seventh. eighth. ninth. tenth and
eleventh levels. y vein, which / will call
the main vein. has been developed from
Il few feet below the eleventh level TO
above the fourth level, with considerable
stopping between these points. However
the drifts along this vein have been run
but a few hundred feet from the shaft
and there is over a half OF this
vein OH the American Flag ground that
can be prospcctcd and developed. This
vein was first encountered about eighty
feet from the portal of the old tunnel, in
which the first discovery of ore on this
property was made. The vein al this
point showed low grade gold values and
WIS drifted on for only fourteen foet.

tai of this tunnel. where "A wnZe 500 feet
deep was sunk. and said 10 be all in ore.
several drifts were run from this
winZe, the longest being at a depth Of
2l5 feet, and at this point the vein is
very strong and runs parallel to the main
vein. but It has not been encountered in
the workings from the main shaft unless.
east of the main vein, on the eleventh
level. may be the same vein. The char
acteristiCs are different, but being almost
500 feet deeper IL might change at that
depth. This vein on the eleventh level
is, as is the main vein. very strong and
persistent and Is highly mineraliZed
Some assays from 1t arc very nigh grade
and three assays taken within few days
are as follows:
Il Gold. 5Os or: silver 29s.5 OF; lead.
G16 per cent value. S2S5.i2 per ton
q per cent: value. s2S.62 per ton.
''5 Gold, LOS o.. silver S@.25 OF. lead,
H.9 per cent; value. 72.3l per ton.
There has been no stoping on this
ground above the eleventh level that may
be developed and stopped upon for over
a half f-mile, and, with the possibility
that the vein from the winze in the old
would he true of that There are doubt

uneXplored territory of this company
which should prove equally as rich. II not
richer than those already discovered.
High grade assays have been taken from
below the eleventh level. and It would
appear that great mine IS below, as
we'll as above
II believe this mine TO be one of the

perience, and | strongly recommend d

volopment without delay. This property.
