GUNNELL AND
GRAND ARMY
ARE EXTENSIVELY OPERATED
IN CONNECTION WITH THE AR
GO TUNNEL.


operating in the Gunnell-Grand Army
mine in Prosser gulch. They work un-
der ideal conditions, as the raise
from the Newhouse tunnel to the
1100-foot level of the Gunnell affords
perfect ventilation, the air currents
being downward and out through the
tunnel.
On the 110O-foot level the leasers
are all in good ore. one ore shoot be-
ing 400 feet in length with smelling
iron from one to three feet wide CIV
ing shipping values of $4,000 to $50. 90
per ton, together with mill ore which
cord.
Practically the same condition pre-
walls on the 10O0-foot level where
there are six sets OF leasers, three
having just started. A heavy ton
mage is being maintained. The Polar
Star mill is operating 25 stamps the
full "a hours on the leasers mill ores.
The management is arranging to
install three additional batteries, as
with other blocks of ground let out,
the present milling facilities would be
inadequate to care for the mill ores.
While but 35 men are now work
ing, there is ground sufficient for
100 more who can obtain blocks on
liberal terms. The healthful sanitary
ic 1ad
by any mine in the state which
speaks well for the present manage
ment. Compressed air fer drilling ma
chimes is furnished by pipe Vine
through the tunnel connections.
On company account, an immense
amount OF work has been accomplish
ed at the tunnel level. The north,
middle and south veins together with
the Hattie and Elizabeth lodes have
been opened and developed at this
point, with results that prove the ore
values are maintained with great
depth. Drifts are in 200 feet west
of the tunnel, the east drift is $50
feet long, the breast being directly
under the Grand Army shaft. This
drift is stulled and equipped with
chutes, the 75-foot level above the
tunnel has been extended 300 feet
west and 500 feet east, all stulled
ready for stopping. Smelter values
range from 2 ounces to 10 ounces in
gold. the ore being the same copper
sulphide as found above in the old
workings.
The completion OF the Newhouse
tunnel has made possible the work
ing Of this property on a much larger
scale than in the past, when it pro-
duced over eight millions in gold.
The tunnel management is pursu-
ing a liberal policy in dealing with
those who operate in the tunnel.
The present rates will be further re-
duced in proportion as the tonnage
increases. The maintenance of the
tunnel being fixed charge, increas-
ed business Is the only way in which
the charges can be lessencd.
1t is interesting to note the sue
cess made by those now operating
through the tunnel. The Prize-Asta-
bula. Is in high grade ore, stopping
is being carried on in the west work
ings, winze is being sunk on the
side showing the vein to be four feet
between walls.
The Dyke is an example of
what may be expected in exploiting
any of the many veins cut by the
tunnel. With a poor showing OF min
eral at the point where the tunnel
cut throught he vein, drifting west
exposed within ten feet handsome
body Of smelling ore. This drift has
been extended 800 feet west and all
in ore from four to six feet in width
Ten cars per day are shipped Of ore
broken in development preparatory
to stopping. Stull timbers and ehutes
are now being placed to care for the
Immense tonnage exposed which evil
IDENTIFY goes up to grass roots.
The Kansas Burroughs vein makes
a fine showing at tunnel level, being
about ~ feet between walls. The
California also shows up we'll. The
Patch with its unqualled body Of low
grade ore exposed for distance OF
$50 feet is we'll worth Investigating.
The Illinois, Ingalls, and a score of
other Quartz hill veins are all ex-
posed by the tunnel workings, but for
some unaccountable reason are not
being worked.
That the above named properties
