low the sill floor OF this leveD from the end
of the east crosscut north drift from east
crosscut has been extended % feet. total
length 80 feet; face in quartz formation
assaying from So to So per ton. On the ninth
floor (the first floor above the sill floor of this
leveD the drift running south from the south
end of the slope has been advanced 18 feet,
total length 172 feet; face in porphyry. At
point feet back from the face of the drift
an east crosscut has been run 10 feet in
porphyry and quartz formation assaying 50
and so per ton. On the twelfth floor the DRIFT
running south from the east crosscut at point
16 feet in from the mouth of the crosscut has
been extended % feet, total length 73 feet:
face in porphyry formation. The upraise
upward from the fifteenth floor alongthe west
wall, one set OF square timbers in size to the
sixth floor, continuing in porphyry, clay and
low-grade quartz 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 has been
carried up feet, total height 43 feet,
the top being in qnartz assaying from SO to
SIS per ton. We have extracted here %
tons of ore. 1850 level-The east crosscut
started from the end of the drift running south
floor has been extended feet, total length 40
feet. The last feet was in solid compact ore
averaging $50 per ton. We have extracted
here 6 tons OF ore averaging $27 20 per ton
We have extracted in all during the week %
tons of ore, the average assay value or which
per mine-car samples was 1913 rs per ton.
from the top of the upraise which was carried
up SO feet above the sill floor of this level
from point in the east crossCut from the main
north lateral drift has been extended % feet,
total length 244 feet; face in clay and quartz
of low assay value
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 112 feet; face in clay and
| porphyry formation. with slight flow OF
water. On the tunnel level the north drift

north drift from the Mexican shaft has been
advanced 10 feet, total length 1872 feet, con-
| tinuing in a low-grade quartz. From the end
| of this north drift We have opened an old west
| crosscut for distance of Is feet in low-grade
| quartz. From the mouth of this north drift on
| the west side and opposite the station OF the
Wine that connects with the $50 levelan up
| raise has been carried up 80 feet in porphyry
| and low-grade quartz.
| MExICAN-1465 level-The north drift started
| from the top of the upraise which was carried
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 ~ feet, total
| length 24S feet; face in poTphyry ana quartz.
As joint work with the Ophir Company we are
making repairs in the Ophir shaft on the HOO
| level and upward.
| from the Union Con. south lateral drift from
the west drift 1920 feet west of the shaft has
been extended % feet during the week, total
| length CAB feet face in q formation of clay and
| porphyry. East crosscut started from
the Sierra Nevada north lateral drift which
was run from the joint west drift from the
shaft ut point 900 feet north from the joint
! west drift has been advanced Il feet, total
! length 262 feet; face in porphyry and clay.
ANDEs-420 level-The west crosscut from end
| of the south drift from the east crosscut from
| the upraise was advanced ID feet, total length
| so feet; formation in quartz and porphyry.
| BEST & BELCHER-250 level-The north drift
| from the bottom of the joint incline winze on
| our south boundary was extended some feet,
passing through porphyry, clay and quartz,
| total length III feet. 800 level-East crosscut
crosscut 4 has been advanced 10 feet, total
! length 800 feet, passing through porphyry.
This erosseut has been discontinued.
| GOULD G. CURRY-200 level-West crosscut 8
which was started in the northwest drift 432
feet from. the main west drift was advanced Ia
feet total length 1341 feet; face in hard por-
phyry. $50 level-The south drift which was
run from the joint incline winze was extended
feet, passing through quartz and porphyry,
total length 81 feet.
HALE l. NoRcRoss-975 leyel-we advanced
the southeast crosscut from west crosscut l6
| feet total length 20 feet. We have stopped
work in this crosscut. 1t has been connected
with our main south drift. West crosscut near
our northern boundary has been extended 10
| feet total length AZ feet; face in solid body
| of quartz, which yields low assays. The south
drift from west crosscut on this level was adj
! vanced feet, total length 100 feet.
There is little ore showing in the face of this
drift. intermediate level-We continue raising
| and sloping OH streak OF ore above this level.
We have done great deal OF repairing in the
mine the past week. We have extracted dur
! ing the week 9 OF ore assaying per mine
car sample $46 So per ton.
| ALTA-During the past week the north drift
on the 900 level was advanced II feet;
| face in quartz of low assay value. From the
| carloads of ore, the average of which, accord
| ing to car samples, is $27 per ton.
