VIRGINIA CITY, New, April 27.-Fol-
lowing are the regular weekly reports Of
the various mining superintendent on the
Comstock lode:
Con. CAL. & VA. MINE-1650 level-On the
ninth floor (the first floor above sill floor of this
leveD the drift running south from the cross
cut running east from the drift run south from
the south end of the Slope has been extended
% feet, total length 43 feet, continuing i'll a
quartz formation aSsaying from 50 to IS per
ton. On the twelfth floor the drift running
south from the east crosscut has been extended
five feet, total length 10Y feet, in loW-grade
quartz. Most of the time was spent in timber
ing the drift The drift running north on the
fourth floor from the opening which was made
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 has been extended
13 feet, total length 50 feet in quartz
averaging so per ton The work here was
mainly tfmbering. 1850 level-The drift run
ming north 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
has been advanced feet, total length 40 feet
the face showing 312 feet of ore assaying from
$40 to $50 per ton. Opposite this north DRIFT
a south DRIFT has been run six feet in ore aver
aging $50 ton. From the upralse which was
carried up fourteen feet above the floor OF the
north drift we have opened out to the south
fifteen feet all the way up, and from the upper
part of the upraise (the fifth floor we have
made an excavation to west Sx6 feet in
ore seven feet wide that assays $50
ton. From these openings we have
extracted during the week 145 tons
of ore, the average assay value of which per
mine car samples was SOL ton. The DRIFT
running southwark on the sill floor of this
level has been extended in southerly course
SO feet. tota length % feet; face In clay and
quartz formation that carries little value.
OPHIR-1465 leveI-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 main
north lateral drift has been extended IL feet,
total length 295 feet; face in porphyry and
quartz of low assay value.
CENTRAL TUNNEL-250 level - The crosScut
running west from the main south drift from
the bottom of the Wine sunk from the tunnel
level at point 80 feet south from the Wine
has been extended 80 feet, total length 60 feet;
face in porphyry, clay and quartz OF low assay
value Tunnel level---The old crosScut running
west from the end of the drift run north from
the end of the west crosscut from the north
drift from the Mexican shaft has been extended
% feet total length extended LOG feet; face in
new ground consisting of porphyry and clay
showing lines of quartz The old north drift
from the top of the upraise carried up 46 feet
above the tunnel level, near the station of the
Wine that connects with the go level has
been reopened during the week 43 feet, total
length reopened 1876 feet, in quartz forma-
ton assaying So and So per ton. Here and
there we find punches of ore that will ASSAY
from $40 to 800 ton.
MExIcAN-I465 level-The north drift started
up As feet above the sill floor of this level at a
point 40 feet west of main north lateral drift
and 100 feet north from the south boundary of
the mine has been advanced 20 feet total
length 80 feet face in porphyry, which shows
little more quartz carrying low ASSAY yalue
AS joint work with the Ophr company are
making repairs in the Ophir shaft on the HOO
level and upward.
