mines:
Con. CAL. & VA.-15O0 level--We con-
tinue running water through the old slopes
at different points, and continue extraction
of ore and filings in working upward from
the sill floor in the old slopes. 1900 leyel-Ne
are repairing the main south drift and the
east crosscut leading therefrom TO the up
raise connection with the 1900 level north
drift. 1850 leyel-The cave continued, max
ing necessary repairs to the drifts on the
sill floor of this level. We continue to eX-
tract some ore from the old slopes, eight
floors up in upraise 6. carried up from
the main northwest drift; also from the old
slopes in working north from the crescent
run west from the northwest drift. We
have extracted during the week FROM the
1900 level slopes and the 1850 northwest
drift openings and raised to the surface $50
cars of ore. or about $50 tons, the average
ASSAY value of which. per mine car samples,
is $50 63 per ton. Shipped to the Morgan
mill 359i400-2000 tons Of ore. Average assay
value per railroad car samples. S31 % per
ton. The Morgan mill commenced to work
this ore to-day

We are retimbeTing the two north cOmpart-
ments of the main shaft above the $50 level.
PoToSI-The east crOsscut opposite the
j u
in porphyry. We have started drift south
from this crOsscut at point 80 feet back
from the face, which shows streaks OF
quartz. The drift is now out 10 feet. The
south drift from the top of the raise 1000
level is out SO feet; face in porphyry and
the top of this 1000 level is out 80 feet
The whole face is in quartz car samples
from which average $50 to S25. We have
completed grading the northwest drift 1900

during the week AL tons, on hand at mill
so tons and 1850 pounds. Average battery
assays S27 OF. Shipped to United States
mint at Carson 40 pounds OF crude bullion.
BULLI0N-The east crosscut 100 feet north
of the top Of the raise from the east cross
cut $50 feet south of the north line 1890 level
