ninth floor 1.-THE first floor above sill floor of
this leveI) the crosscut running east from the
drift run south from the south end of the Slope
has been extended IA feet, total length 81 feet,
continuing in porphyry and quartz. From this
east crosscut at point % feet in from its
mouth south drift had been run Is feet in
a quartz formation. assaying from 50 to So per
ton. On the twelfth floor the drift running
south from the east crosscut has been extended
10 feet, total length 102 feet: face in lowgrade
quartz; most of the time was spent in timber
ing the drift. The drift running north on the
fourth floor from the opening which was made
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 extended
80 feet, total length 40 feet: face in lowgrade
quartz
1850 leyel-The drift running north from the
end of the east crosscut started from the end of
the drift running south from the south end of
the stope on the fourth floor above the sill floor
on this level has been advanced IA feet, total
length 81 feet, all the way in ore; the ore in
the taee averages $33 80 per ton. From this
north drift at point 20 feet in from its mouth
we have carried up an upraise IA feet OF the
size of one square set OF timbers opening at the
H1ln 0OOr III ore dSSdyliB PfO per Ton. FROM
this locality we have extracted during the week
123 tons of ore, the average value of which per
mine-car sample was Sol rs per ton. On the west

$50 level. We have reopened an old north
drift for distance OF SO feet, the last 40 feet
being in quartz formation which assays So
and SO per ton.
