VIRGINIA, June q.-Following ara the
superintendents' reports of the mines for
the past week:
Cox. CAL. & VA. MINE-165O level
The opening which was reported last
week as having been made from the top
of south drift l in the ore body recently
found has been extended further east four
feet IN ore OF high grade. making the total
length east and west of high-grade ore Is
feet. The top of this opening for this dis
lance is in ore Of lower grade. A further
extension of this opening east eight feet
shows ore of low quality. Commencing
at the mouth of south drift; 5, % feet be-
low south drift !, we Lave stopped out over
this drift TO the south five sets of timbers
(25 feeU. all in coed ore. bounded on the
east SIDE by clay selvsge which separates
the ore body from the vein matter which
lies on the east side of il. South drift 4
on the 100 level has been Teopened and
repaired during the week 80 feet TO
point 142 feet distant south from
the Wine. This drift will be axreuded
to a point which will be reached about the
middle OF the coming week, when a cross
cut will be run out to the west TO find tbs
ore body where it would lie on this level
Judging from ite trend and dip in south
drift 3 % feet above. The ore extracted
during the week amounted 10 al car
l0ads-abOu, 40 tons-the average assay
value Of which, per car Elple, was S94 90
per ton. This ore came from the workings
above described, in ground bordering south
drift and south drift 3. 1000 level-The
Rule drift-FrOm uprase on the east side of
the main drift $50 feet south from the
shaft station at point 81 feet up a south
drift has bean advanced 90 feet in por-
phyrY, with streaks Of clay and quartz of
low assay value. AT point 80 feet south
from The shaft station an east crosscut
from the main drift has been advanced II
feet in quartz formation, giving assays of
So and S4 per ton. Much necessary repair
work has been done in the main drift dur
lDg the week.
UNIoN-9OO level-The Union and Sierra
Nevada joint north drift which was run
from the joint west drift at point 1920
feet west OF the shaft has been extended
during the week 10 feet, total length 400
feet; face in hard DOrpbyry. The joint
south lateral DRIFT from the joint west drift
at point 1920 feet west OF shaft has been
extended II feet total length 4S feet; face
in ci"y and DOrphyry.
MEXICAN-1i65 level-The west crnsscut
started from he top OF the upraise which
was carried up 45 feet above the sill floor
of this level at a point 80 feet west from
the main north drift and 100 feet north
from the south line of the mine has been
extended during the week % feet. total
lie 9Th so feet; face in porphyry and
streaks of quartz OF nominal value.
OPHIR-1465 level-The DRIFT running
south from the crosscut run west from the
main north drift at a point 2l9 feet in
from the mouth of the erosscut has been
extended during the week IS feet, total
length 156 feet, continuing in porphyry
formation carrying lines of quartz of low
assay value. Have continued Jointly with
the Mexican company the work of making
repairs In the incline shaft which extends
downward from the 1865 level station of
the Ophlr shaft. Central tunnel-The
west crosScut started from the drift run
north from the old Mexican shaft on the
tunnel level at point &c fest north from
shaft has been extended 30 feet, total
length 80 teet, continuing In pOrphyry and
clay. The west crosscut from the drift
run northwesterly from the shaft Sc feet
ABOVE the tunnel level at point 60 feet
from the shaft has been extended 81 feet,
total length 104 feet 1t passed through
four feet OF clay and entered the ledge in
the old slope, and from The material
herein found we obtained assays of SD 80
per ton.
ANDEs-420 level-The upraise from
the west crusscut that connects
the north lateral drift with the main
north drift has been carried up nine feet,
total length 40 feet; formation quartz and
porphyry.
HALE e. NoRCRoSs-990 level-West
ccosscut from end TO southwest drift was
advanced IL feet, total length 1000 feet;
face in porrhyry ana lunches of quartz.
100 levei-East crosscCt from end Of main
south drift on this level was advanced IL
feet, tota! length "A feet. The face OF
this crOsscut has reached The east CLAW
wall of the ledge and crOsseut stopped. A
new east crosscut will be started to-day
