VIRGINIA CITY, May Appended will

dents of operations in the Comstock mines ::
Con. CAL. & VIRGINIA-150o level-We
have continued to extract ore and old fill
ings in working upward in the old south
slopes from the tenth to the sixteenth
floors above the sill floor of this level.
1850 level - We have continued making
necessary repairs to the drifts on the slli
floor Of this level. We continue 10 extract
some ore from the old Slopes eight floors MP
in the upraise, No. g. carried up flOm the
main northwest drift; also from the old
slopes in working north from the cr0sscut
run west from the northwest drift. From
a point 60 feet up in the upraise, which was
started from the shaft run west from these
north workings 27 feet above the sill floor
of this level an east cr0sseut has been
advanced 40 feet in pOrphyry and quartz of
low assay value. We have continued to
stope out ore of fair quality in working on
the north and south sides of the drift run
east at n point 20 feet down from the
winZe which was sunk from the crosscut
run west from The main northwest drift.
From the end of the drift run south from
near the bottom of that winze, 81 feet
down, the east crosscut has been advanced
13 feet, makiI the total length so feet, and
from the end of this east cTosscut an upraise
has been carried up and connected with the
fourtl-hOOI workings, which are 20 feet be-
low the sill floor of the 1880 level. This up
raise, passing along old timbers, carries
some pay ore. We have extracted during
the week from all parts Of the mine 567
cars of ore, making about $50 tons. Shippe d
TO the Morgan mill 662 tons 6l0 pounds
of ore; average assay value, per railroad
car samples. S27 H. The assay value per
battery sample If all the ore worked at that
eIa aa1rg ~ %
per ton. Shipped bullion to Carson mint
of an assay value of S32. 600 67.
OPHIR-590 leVel-jointly with the Mex
lean Company we continue doing necessary
repair work in the west drift from the main
shaft. 1865 level-The west crosscnt started
from the bottom of the wiGZe sunk 81 feet
below the sill floor of this level has been
advanced % feet, total length 40 feet; face
in porphyry, clay and quartz formation,
which carrys low assay value.
MENICAN-1565 level-West crosscut 2
from The north drift from the east crOsscut
from the winze sunk from 1855 level down
to this level near the south boundary has
been extended 90 feet. total length 1856 feet,
continuing in a porphyry formation carry
ing clay separations. 800 level-We have
continued making necessary repairs Jointly
with the Oshir Company in :he west drift
from the 0phir shaft on this level.
SIERRA NEVADA-The intermediate tun-
mel on Cedar Hill has been advanced during
the week II feet, making the total length
326 feet; face in hard pnrphyry. The joint
Sierra Nevada and Union west drift SEQ
level has been advanced 13 feet, making
the total distance west of the joint shaft
3156 feet. The face is in porphyry and
streaks of quartz, from which there is q
strong flow of water.
ANDEs-420 level-From the north drift
from east crosscut l north a west cross
cut has been advanced IL feet, total
length 25 feet; formation in quartz and
porphyry.
GOULD & CURRY-20O leyel-During the
past week west crOsscut 3, started in
the northwest drift, 432 feet from the main
west drift has been advanced IA feet,
total length AGO feet; face in hard porphyry.
Sutro tunnel level-On this level we are
now running an east erosseut 10 make con-
nectlon between our winze from the 1000
level and the joint north drift.
BEST & BELCHER-200 Ievel-At n point
in the northwest drift 230 feet from our
south line we have started west crosScut
and advanced the same IS feet, passing
through porphyry and QuariZ total leng, h
GO feet. 800 evel-At point in the south
west drift ll2 feet from west crosscut 3
we have started west crosscut and extended
the same distance of 16 feet, total length
% feet; face in porphyry and stringers of
quartz. Sutro tunnel level-We are now
running an east crosseut n make connec-
tion between the Gould IL Curry wnZe.
which was carried down by them from the
1000 level, and the joint north drift
HALE IL NoRCRoSs-1S00 level-We have
started the new upraise in the west cross
cut on the south boundary and are working
on the second floor above this level The
Top OF the raise IS nearly all in quartz
Main shaft-We have started to retimber at
the 1890 level and are repairing the main
incline in places where most needed.
CHoLLAR-We are repairing the west
crosscut 450 level and retimbering the top
of the main incline $50 level The east
cr0sscut near the south line $50 level is out
172 feet; face in soft poTphyry and clay.
PoTosI-The north drift from the east
crosscut $50 level Is out "a feet; face in
porphyry and seams of quartz, which give
low assays. The upraise so feet south Of
the Potosi Wine $50 level is up GO feet. The
formation in the top is pOrphyry The
north drift from the east ciosscut opposite
the POtos winZe $50 level is cut 80 feet,
following a 3-toot streak Of quartz that
gives fair ASSAY. The west crescent from
the south drift 930level is out IA feet. fol-
lowing three feet of fair grade quartz Tie
south raise 1000 level, which is up 20 feet,
shows at the top five feet of fair-grade ore.
The north raise 1000 level is up IS feet on
the stope; formation in pOrphyTy and low
grade quartz Extracted and sent TO the
mill the past week 54l tons and 1850 pounds
of ore from the 500, $50, 1000 aud 1850 levels.
