Underground Work

VINGINIA, New, Feb. 22-Followine are
the official letters of the superintendent
Con. CAL. AND VA. MINE-1650 Ievel-We
have continued to stope out ore from the
new ore body, above and below the sill
floor of this level, from the sixth floor up
to the ninth floor. On the sixth floor the
south drift, started at the south end of the
slopes, has been advanced 80 feet. total
length 81 feet; face in porphyry, clay and
low-grade quartz. On the ninth floor the
excavation made on the east side of the
drift run south from the south end of the
slopes at point 10 feet back from the face
OF the drift has been enlarged to the size of
20 feet in length, north and south. by Is
feet in width. On the east side we have
sunk the size of one square set down to
the eighth floor and appraised on the west
side to the tenth floor. All these openings
have yielded few tons of ore averaging
$35 so per ton. On the twentieth floor
the fourth floor above the sill floor of this
level-the south drift started at the south
end OF the slopes has been extended feet,
total length from south end of slopes 50
feet; face in porphyry and low-grade
quartz. Nine feet back from the face of
the drift an east crosscut has been adj
vanced Is feet; face in quartz formation
assaying about $40 per ton, Back from
the face feet is a streak of ore inches
wide that assays $40 per ton. The south
Drift from the east crosscut from the main
north lateral drift on the sill floor of this
level, started at point 200 feet north from
the Con. Va. shaft, has been extended ~
feet; total length As feet. This drift is in
quartz formation with spots and streaks
of ore from which we have saved few tons
assaylng $25 per ton. 1850 level-No ore
has been extracted during the week between
the sill floor of this level and the 100 level.
The east crosscut started from the north
drift on the fourth floor 81 feet in from it's
mouth has been extended Is feet. total
length Y feet; face in quartz formation of
low grade. From the south end of the
Slopes on the fourth floor south drift has
been started In Quartz formation assay
ing 81 and 30 per ton. About "a tons of
ore have been extracted during the week
from all of the aforementioned openings,
the average value of which per mine-car
samples was $38 4S per ton. We shipped
to the Morgan mill 299 tons and no pounds
OF ore assaying per railroad-car samples
S53 40 per ton. The average assay value
per battery samples of all the ore worked
at that mill during the week-f42 tons and
1850 pounds-was $46 81 per ton The bull
lion shipped to the Carson mint had an
assay value of $39, 554 70.
OPHIR-1465 level-The drift running
north from top of upraise which was car
rled up so feet above the sill floor of this
level from point in the east crosscut from
the main north lateral drift has been ex-
tended Is feet, total length 131 feet; face in
porphyry, clay and quartz, which carries a
low-assay value. Central tunnel-The up
raise started at point in the south drift
on the $50 level of the mine liz feet south
from the bottom of the Wine sunk from
the tunnel level has been carried up three
feet, total length % feet; top in porphyry
and quartz. From the top of the upraise a
south drift has been advanced 80 feet in a
porphyry and quartz formation, assaying
" and 50 per ton. A northwest drift
started from the upraise from the end of
the west crosscut from the northwest drift
from the Mexican shaft (S4 feet above the
