The mill at the Montana treated
s25 IONS of ore during the week and
obtained an extraction of 81 per
cent. In the workings of the mine
159 feet of development work was
done.
39O-foot level-The east drift
from the south crosscut on the fault
was advanced fourteen feet. The
face shows small stringers of min
eralized quartz but up to date no ore
of value has been encountered. The
west drift on the Martha vein was
advanced fourteen feet and the face
shows two an done-half feet of good
milling ore. During the past week
considerable work has been done
along the western portions of the
stope where the vein averages about
three feet of good milling ore. The
cutting out of a stope is being taken
over the west drift where the vein
of good milling ore has been exposed
for four feet in width. The stope on
the Macdonald vein about $50 feet
west of the shaft shows an average
width of three feet of milling ore.
462-foot level-The west drift on
the Triangle vein advanced eight
feet and the face shows three feet of
very good milling ore. The values
in this ledge have increased material
ly during the past week and ind;.A-
tons point toward the body turning
out to be the equal of any of the
others in the property. The cutting
ont of a stope over the east drift Is
being taken at a point where the
vein is bunchy and will average about
eighteen inches of good milling ore.
A small quantity of good ore was
broken in the Macdo.aId stope, 1000
feet west of the shaft. The ore was
extracted from the central and vest
ern portions Of the stope.
515-foot level-The west drift on
the South vein was advanced twelve
feet and the face shows about two
and one-half feet of good milling ore.
A raise is being started from this
ore shoot to connect with the level
above. The face in the east drift on
the Martha vein, which was advanced
eighteen feet, shows two feet of fail
grade mill ore. A raise has been
started at a point about fifty feet
from the face to locate the ore SHOOT
on the level above. Stopping on tht
Martha vein on this level continue:
at a point where the vein averages
about twenty feet in width and /, OF
a milling ore grade. The general ap-
pearance of this Slope shows consid-
cradle Improvement over the last
weeks showings. The cutting out
of a stope is being taken over the
west drift of the Mizpah vein and It
is now being timbered.
565-foot, intermediate level-The
drift east from the Wine on the
South vein advanced seventeen Test
and the face shows three feet of fair
milling ore. The south crosscut from
the east drift on the Martha vein.
which is being driven along the fault
advanced eighteen feet. In the last
few feet the crosscut has been fol-
lowing a body of quartz that carries
small values. A west drift is being
driven at right angles to prospect this
quartz matter.
6l5-foot level-The crosscut west
OF the main south crosscut, which is
being driven to connect with the
winze on the Martha vein. advances
t~hirty-two feet and expects to make
the connection in another sixty feet
There is no change in the Slopes on
the Macdonald vein below this level
and ~ the A B K and Martha veins
above tn level.
765-foot leyel-The crosscut north
was advanced fifteen feet, during the
week and is now out 1881 feet from
the station. Progress has been de-
layed by the bad air and the air pipe
line has now been laid within 1oJ
feet OF the face, which improves the
ventilation considerably.
