F. A. Tritls. Esq. President Yellow
Jacket Silver Mining Company-Dsar
Sir: Following is o report OF work dons
in the mine and improvements made on
the surface and in the shaft during the
past year;
The shaft has been sunk and tim.
bored 3S9 feet. making the present
depth to the bottom Of the stump 1925
feet. Stations have been opened at the
27OO, 2s2s and 5000 levels. and o drift
started to the southeast from the bottom
OF the stump, to increase the capacity Of
the same.
On the 27O0 level . lateral drift has
been run from the shaft south $50 feet.
or to q point 100 feet north Of the south
line; and north from the shaft to . con.
nection with the workings OF the lmpe.
rial mine (2s00 level). Two crossdrifts
have been run west from this lateral drift
to the footwall OF the vein; u OF them
$50 feet south OF the shaft and the other
$50 feet north Of the shaft. These two
crossdrifts passed through vein por.
phyry and quartz seams, which gave
low assays. A drillhole was bored east
from the shaft on this level. which ct q
distance Of ITO feet cut q strong dow OF
water. which was stopped by plugging
the hole. Three hundred and fifty feet
north OF the shaft an incline winze has
been sunk on o slope Of 40 degrees to
the eat 2S6 feet below the 270O level. or
about 200 feet vertically. at which depth
much water was encountered. We are
now drifting on the 1928 level for a con.
nsction with this winze for the purpose
OF ventilation.
On the 2s2s level we have started q
drift to the east from the station and
have run Q drift south from the shaft
$40 feet to Q connection with the work.
ings Of the 2760 level Of the Belchsr and
Crown Point mines. We are now hoist
ing rock from this level for the above
named companies; also from the 27Oo
level for the Imperial and other mines.
At the 5000 level we have opened q
large station and are about starting q
DRIFT east from the same for the vein
which ut this level 10 distant about 800
feet.
In the shaft we have made the neces.
sary excavations for pumptanks-twslve
in all and stations for balance-bobs-
sipht in number-timbsrsd the same
and erected the necessary tanks and
bobs; have built up 3025 feet OF l6Il6.
inch pumprods and connections. and
built foundations and placed on the
same thirteen 14.inch pumps with ID.
inch pump-column and connections to
the surface. All OF these pump founda.
lions below the Sutro tunnel level (l520
feet below the surface) are constructed
for q double line Of pumps. the intention
being, after Q connection 10 made with
the Sutro tunnel, to take the six pumps
above the tunnel level and place the
same below the tunnel level, which will
give q double line OF l4.inch pumps, or
double the present pumping capacity.
This work has all been done during the
past six months, during which timo but
little prospecting work has been done on
account Of the danger Of cutting nor
water than could be handled with tanks.
The pumping machinery has all been
put in motion and found to work very
we'll, pumping the water to the surface,
or some $3.50 feet.
We are now prepared TO carry on the
work Of exploration with little fear OF
DELAY by water. It will require fully
twelve months to thoroughly prospect
the large block Of ground between the
$500 and 5000 levels already accessible
from the shaft. and in which but o lin.
tied amount Of work has been done and
no cross drifts to the east have been
made.
The double horizontal hosting on.
sines. % inch diameter by 96.ineh
stroke OF cylinder. contracted for last
year, have been received and erected.
which, together with the pumping ma
chinery, gives the Yellow Jacket s. ii.
Company u mining plant inferior to
none, and with which We should earn q
revenue from the adjoining mines SUI.
ficient to materially reduce the cost to
stockholders for prospecting the mine,
and which. in the event OF the develop
ment OF an ore body. places the mine at
once on Q paying basis, as we possess
about every required appliance for eco-
nonically working the same. The ven.
tilation Of the mine Is good and the ma
chiusry in excellent condition.
During the past year there have been
1864 feet OF drifts run. 1922 feet Of holes
bored with the diamond drill. GSl feet
Of WINES sunk. and the shaft sunk and
timbersd $50 feet.
The disbursements for improvements
consisting OF hosting engines and
their erection, ropes for the same,
pumps, column. rods, hobs. and th
NECESSARY labor to construct The pit
work-have been very heavy. and rep
resent fully fifty per cent. Of the e1'
psnses Of the mine during the past year,
and which, being o provided, Will IN
the future require but the necessary out
lay to keep in order.
Owing to the delay Of late in extend,
ing the south header OF the Sutro tunnel
towards the shaft OF this company. i
would recommend that arrangements %
made whereby the Yellow Jacket Silver
Mining Company may start q drift rom
its shaft towards the south header OF the
tunnel. and thereby the sooner receive
the benefit Of . connection with the
same for drainage purposes. Yours,
respectfully.
