DEVELOPING TONNAGE
FOR REDUCTION PLAN.
American Exploration Company "a
Prospect American Flag Mine
For Other Orc Bodies.

Expecting that development in the
American Flag mine ut Park City will
show that the three veins in the prop
erty are one and the same and that at
The same time enough orc will be
blocked out to warrant the erection
of reduction works, Engineer f. V.
Bodflsh OF the American Exploration
company, in report just made, is adj
Vising that the mine be opened up In
such u manner as TO prove this contcn-
ton
The American Flag mine controls 300
acres In Park City between the silver
King Coalition on one side and the
Ontario on the other. It is developed
by|a vertical shaft down 1910 feet The
bottom Is known as the 18th level The
ore was struck In this shaft ut
SEQ, but no extraction was made until
the tenth level was reached. From
here down to the eleventh level 1t IL
estimated that 100000 worth OF ore
was shipped. Since that time the vein
has been worked up to the fourth level
but here the shipping ore seemed IN
stop. Mr. Bodhsh. and also r. l..
Mack examined the property, and part
of the report is as follows:
The ore bodies are practically the

In this property there are three kinds
Of veins. First is the lme-quartzite
contact; second, the McGregor assure
which is fault hssure sometimes
partially and sometimes wholly filled
with porphyry: third. the Alliance
Crescent assure which Ia II nssure in
the limestone entirely filed with por-
plhyry. In the Ontario the assures arc
in quartzite. The formation of the
American Flag Is Identical and similar
ore occurrences may be expected
The veins i'll the American Flag have
the following characteristics: The main
vein Is a fault assure in quartzite which
appears TO have been originally filled
with porphyry. Ore In places has re-
placed the porphyry, The vein filling
is fragmentnl In character; ground UP

wall Is the quart2itc but on the elev-
enth level both hanging wall and foot
wall are luartzitc The east vein is
20 feet east of the main vein This is
a narrow iissure and Is probably n split
from the main vein The Rhodin vein
Is probably the south extension of tile
main vein fauitcd IS feet east bv tho tho
porphyry dixie. There are other north
south Veins"
The Rhodin vein was originally de-
Neioped by tunnel. The shipping
ore was extracted down to the 225-ft.
Level. The report shows that It is the
contention Of Mr.. Bodfsh that these
veins sare the same. and that some
laulting has occurred in the vein by
the intrusion of tho porpsiyry dixie. On
the 400. a drift run through this dixie
on the vein still shows excellent values.
The basis upon which the rcport recon.
mends operations is to develop the nine

american Exploration company has n
flve-ycar lease on the mine Under this
plan is estimated, that from $4,000 to
$4,000 tons OF ore could be opened UP, On
account OF the excessive smclter chnrg-
es IT Is estimated that with concen
tration and cyandation plant that AZ
per cent OF the costs could be saved
besides making 1t possible to extract a
bigger tonnage than otherwise. The
smelter charges are claimed to be over
80 per cent the value Of the ore and
by such Il process considerable OF n
saving could be made
From Aug. 3. 1904. TO Sept. 1, 1910, the
American Flag shipped S,55O2 dry tons

smelter charge was s7.3. Since tho
operation of this lease in September,

American Exploration company is an
of the Western Develop

patterned after the Guggcnhclm Ex-
pioratton company. 1t has several
other large undertakings in this state.
