ents of operations in the Comsto mines:
Con. CAL. AND VIRGTN1A-The south
west drift started 70 leet below the sill
Haor has been advanced 30 feet in a quartz
formation Of low grade value. From the
END of the southwest drift west drift has
been advanced - feet. The first feet is in
ore Of an average assay value OF S25 per ton,
and the last feet are in quartz formation,
ASSAY 50 to 81 per ton. 1850 level-We have
continued making necessary repairs to the
drifts on the sill floor of this level and TO
extract some ore in working west from the
cd slopes on the third floor, operating
through the uDraise No. 6, carried up from
The main northwest drift, also from the
old Slopes in working north from the
crOSscut run west from the northwest
drift. A south drift started at the end of
the crOsscut run east from a point 60
feet up in the upraise which was started
from tile DRIFT run west from the north
workings 27 feet above the sill floor of this
level has been advanced SO feet, total
length us feet, formation quartz md por-
phyrv, showing some value We have
continued TO extract some ore of fair quail
ity in working on the north and south
sides of the drift ruu east at a point 90
feet down from the Wine which was sunk
from tie cT0sScut run west from the main
northwest drift. We have extracted dur
ing the week from all parts of the mine
800 cars of ore making about 225 tons, the
average assay value OF which, per car
sample, was S25 65 per ton. The assay
value, per battery sample, OF all the ore
worked at the Morgan mill during the
week $50 tons was S23 IS per ton. The
Morgan mill has been shut down and the
cleanup of bullion from that mill has been
sent to the mint, the assay value being
S24.134 o..

formation Of low assay value. We have
continued the work OF making the neces-
sary repairs IN the shaft, being joint work
with the Mexican Company.

total distance west Of the joint shaft 1910
feet; the face is in hard porphyry.
ANDES-On 420 level have cleaned out
erosscut and put in car track 10 north
lateral drift. In north lateral drift put in
car track TO east crosscut ), and will use
thissateral drift instead of the main north
drift
GOULD & CURRY-2OO level = West

feet from main west DRIFT, has been ad-
vanced eight feet. total length 4SS feet /;
face in hard porphyry Also did some re-
pairing on the 800 and 400 Levels during the
past week. Sutro tunnel level at point
in east cTosscut l, 70 feet from the main
north drift, we have started jointly with
the Bssi u Beicher Company north ON a
streak OF quartz and extended some 10
feet; face IN porphyry and quartz. Also
did considerable repair work during the
week
BEST & BELCHER-2O0 level-During
tile past week west cr0sscut 2, started in
northwest drift, go feet from our south
line, has been extended 16 feet, total

quartz yielding low assays. Main shaft
Are retimbering above the 1900 level and
continue making the necessary repairs in
main incline.
CHoLLAR-ihe repairs to the north drift,
$50 level, are not yet COMPLETED; the east
cr0sscut near the south $50 level is out 246
feet: face is in porphyry.
PoTosI-The north drift from the east
crosscut on the $50 eyel has not been adj
Vanceu on account of timDering. The
south raise 80 feet south of the POtosi
