GOULD e. CURRY - 200 level - West cross
cut which was started in the northwest
drift 432 feet from the main west drift was ad-
vanced feet, total length 1850 feet; face In
hard porphyry. 25O level, The south DRIFT
which was run from the joint incline winze
sunk on our north boundary, was extended
feet passing through quartz, clay and por-

HALE & NoRCROss-975 level-We have
started No. l east crosscut from our main south
drift at point so feet south of No. west
crosscut and advanced the same IL feet; face
in pc rphyry and seams of quartz. West cross
cut 8 near our northern boundary has been
extended 8 feet, total length 90 feet face in
quartz and porphyry. The south DRIFT from
No. l west crosscut on this level was advanced
1S feet, total length 16S feet; face in por-
phyry and stringers of quartz. The usual re-
pairs were made on this level the past week.
intermediate le' Give continue Stopping on
small streaks of ore above this level. We have
extracted during the week Ia cars OF ore as
saying per mine car sample 1913 II per ton;
CHoLLAR-The north drift from the 45O level
winze $50 feet south of the north line is out II
feet and the face is in porphyry and loW-grade
quartz. The west crosscut from the north
lateral drift of the $50 level to connect with
the raisejfromthe eighth floor OF the north stope
is out 80 feet. The formation in the face con-
sists of low-grade quartz. The top of the drift
for distance of 10 feet from the face shows
punches and powders of good ore. The west
crosscut on this level 30 feet from the north
line is out SO feet and the face is i'll porphyry.
The raise from the north drift on the $50 level
has been connected with the bottom OF the
Wine from the $50 level 80 feet from the
north line and the timbering OF the same is
now being completed. The connection affords
us a good circulation OF air, FROM TINS point
| and from the openings so feet south OF the
| north stope between the 40 and 800 levels we
are extracting ore OF fair grade, the yield Tor
| the week being 176 tons 16OO POUNDS, when
| has been shipped to the Nevada mill for reduc-
ton and the average battery sample OF which
| was $26.
PoTosI-The south drift on the $50 Level from
| the bottom of the $50 level winze is out 10
feet, 10 feet having been added during the
week; face in porphyry and streaks OF quartz,
the latter assaying from So to $40 per ton.
| From the raise above this drift which was
started last week we are saving some fair grade
| ore from q streak of pay feet wide in the top;
| the yield from there was 13 tons 1900 pounds,
| the assay average car sample OF which was
! $25 "a.
| 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
point So feet west of main north lateral drift
| and 100 feet north from the south boundary OF
the mine has been advanced % feet; total
leng tn 273 feet; face in porphyry carrying a
| low assay value.
ALTA-During the past week the north drift
! of the $40 level was advanced ID feet; total
length 226 feet; face in quartz of low assay
value. The winze above the 825 level con-
ttnues to yield two carloads of ore per day,
averaging an assay value as per car sample OF
$32 rs per ton.
