point 125 feet south OF. the vertical winze
which connects with the 100 level a
south drift has beenH run 10 feet in quartz
formation, assaying from So to $40 per ton.
From the same point north drift has been run
IL feet in quartz, carrying the same value
On the ninth floor (the first floor above the
Sill hoor OF this leyeD the drift running south
from the south end of the stope has been adj
vanced 10 feet, total length l18 feet; in por-
