RUSH MINE IMMENSE


Rush" suggests. and with substantial
results that bid fair to develop C rival
to the Montgomery Shoshone and the
Gold Bar-two of the unquestioned big
gest mines in Nevada-the Bullfrog
Rush. practically unknown three months
ago. is taking its place among the list
of big ones. such as have made the Bull
frog district the envy of all sister
camps in the state and placed it first and
foremost in the esteem and confidence
OF Americas greatest operators.
just three months have passed since
Prof. G. f. Bailey commenced to explore
the Rush estate. which cuts a slice.
hgurately speaking. out of the heart
of Bonanza mountain from east to west.
During the 80 days. more than 1000 feet
of work nave been accomplished in
trenches. tunnels, drifts, c~rosscuts,
wines and raises, 500 feet of the under
ground work having exposed values.
The principal work has been lone on
the big Rush ledge on the west side OF
the mountain. The underground work
has not proceeded to the state of prov
ing i'm full the extent of the deposit as
suggested by the surface indications,
for the ledge at the mouth of the north
lateral is 154 feet in width between well
defined walls; yet the development 10

the ledge has been penetrated and ex-
plored the values obtain, giving no dis
appointment whatever, but on the other
hand the most encouraging results.
The development work to date on the
Rush ledge has demonstrated the values
over a length of 400 feet in the Yolo
tunnel and north lateral, which work.
ings were started 500 feet apart, the
Yolo tunnel being the lowest and most
southerly, both tunnels drifting to the
north on the ledge. In the crosscuta
from the north lateral the ore has been
proven for a width of rs feet. exposing
only the hanging wall, while in the main
crosscut tunnel, the ore has been proven
for a width of SO feet with only the
footwall exposed. Coupling the crosscuts
as one. the total width exposed e~asterly
from the workings is lis feet, with
about 40 feet intervening between the
face of the crosscut tunnel and the
Wine, which is being sunk from the
north lateral to connect with the cross
cut tunnel, so feet below. These figures
indicate that the ledge is more than
holding it's own at depth without taking
into consideration the dip of the vein.
Milling values obtain for a length of
1876 feet in the north lateral. where the
crosscuts show 75 feet of ore in width.
Milling values also obtained in the SO
feet of ledge matter exposed in cross
cutting the ledge in the main tunnel.
These figures are being increased
with each round of shots, as the face of
either tunnel is in good ore, a fact that
was demonstrated conclusively to a
Herald reporter who visited the prop
erty Tuesday. The north lateral has a
vertical depth in the face of about 100
feet, the winze will meet the main
crosscut so feet lower. and the Yolo
tunnel will have more than 100 feet of
additional depth when this point is
reached. 1t will be only a matter Of
mathematics, in a few weeks, to calcu-
late the amount of milling ore blocked
out in these workings, as they are all
centering toward a common objective
point, defining the ore in length and
width and upon three different levels.
1t is suffice to say at this time that with
the present showing of milling values
there are few peers in the
camp to the Rush development, and with
the magnificent results that are prom
Used when the exploration scheme is
completed, there is every reason to be-
lieve that the Rush will be second to
none of the districts biggest mines.
Starting from the Yolo c~ompany's
ground, which affords the tunnelsite, a
drift is being run northerly along the
hanging wall which is clearly define
This may be continued 1900 feet through
Rush ground along the ledge which is
easily traceable for more than a mile
~northerly from the Rush holdings. TIL
Yolo tunnel is in fair values, which
have increased as work has proceeded,
and a crosscut has been started to de-
termine the extent of the deposit 225
feet under cover. From this tunnel the
ore from all the workings may be mined,
the elevation being such as to afford a
side track from the proposed line of
railway. This will eventually be the
main working tunnel on the Rush ledge.
In addition to the work noted, numer-
Gus prospect tunnels, from so to 100
feet, have been run at different points
to determine the character and position
of the vein, and a score of open cuts
have been made to further explore the
ledge.
On the east side of the mountain, the
development of the northerly extension
of the Denver ledge has been taken up.
Several tunnels and cuts have been run,
exposing the ledge at intervals for 1900
feet, values obtaining in all the work
ings, and extensive work is in progress
drifting on the east wall to get depth.
The Denver ledge is traceable for three
miles on Bonanza mountain, extending
into Busch Peak on the north. A shaft
is being started on the Index claim to
penetrate the Denver ledge.
Altogether. the Bullfrog Rush is much
in public favor, and it's development into
a big producer adds much to the future
of the camp, as in all probability the
company now in possession of the prop
erty will build it's own mill and operate
upon an extensive scale. It's close prox-
unity to Rhyolite emphasizes the local
