VIRGINIA CITY, New, April 13.-Ap-
pended are the reports of the various min
ing superintendent on the Comstock lode:
Con. CAL & VA MINE-1650 level-On the
sixth floor in the new ore body 1.-THE second
floor below the sill floor OF this leveD north
drift from the east crosseut 80 feet in from
the crosscut has been extended 3 feet in q
quartz formation OF low assay value. On the
ninth floor the crosscut running east from the
drift run south from the south end of the stope
at point feet back from the face of the
south drift has been extended 81 feet, total
length 43 feet, continuing in porphyry and
quartz formation assaying 20 and SIS per ton.
On the twelfth floor the drift running south
from the east crosscut to a point IS feet in
from the mouth of the crosscut has been ex-
tended 10 feet, total length 81 feet face in g.
porphyry formation.
No work has been done during the week in
upraise carried up from the twelfth floor to the
sixteenth floor. From the opening which was
started from the drift run south from the end
of the east crosscut from the main north lateral
drift on the sill floor of this level carried up 43
feet, north drift started on the fourth floor
has been run 10 feet In low-grade ore From
these openings we have extracted IL tons of
ore, assaying $37 20 per ton.
1850 level-From the end of the east crosscut
started from the end OF the drift running south
from the south end OF the stope on the fourth
floor above the sill floor on this level a north
drift has been advanced 20 feet all the way in
solid ore. 1t is feet in width at the mouth
and widening to feet in the face. The top
and the bottom of the drift are in good ore and
the face is all in ore averaging $50 per ton We
have extracted from this locality during the
week ~ tons OF ore, asSay1ng T55 80 per ton
We are cutting out on the west side of the
south drift on the sill floor OF this level at O.
point / s. feet north from the incline winze sunk
from the 100 level and will extend the drift
southwark from that point. The total ore ex-
tracted during the week from all points was
100 tons, the assay value OF which was, per
mine Car samples $50 81 per ton.
OPHIR-1465 level-The drift running north
from the top of the upraise which was carried
up 80 feet above the sill floor of this level
from point in the east crosscut from the
feet, total length 25S feet; face in porphyry
and quartz Of low assay value. We have con-
tinued jointly with the Mexican Company the
work of making repairs In the main shaft
from the 100 level upward.
Central Tunnel-250 level-Northeast drift
3 running from the southeast drift at point
125 feet in from its mouth has been extended
20 feet, total length 1872 feet, in clay and
porphyry formation with an increased flow of
water from the face.
Tunnel level-The old crosscut running west
from the end of the drift run north from the
end OF the west crosscut from the northdrift
from the Mexican shaft has been reopened So
feet, total length ~ feet, in low-grade quartz.
The upraise started from the north drift on the
west side and opposite the station of the winze
that connects with the $50 level has been car
ried up 10 feet in porphyry to total height eff
46 feet and connected with the old winZe,
which has been reopened down to point 46
feet above the tunnel level.
UNION CoN.-9O0 level--The west crosscut
(near the south boundary OF the Union Con.
mine) from the Union Con. south lateral drift
from the west drift 1920 feet west of the shaft
has been extended 81 feet during the week,
total length 664 feet; lace in q formation OF
