MONTANA-TONoPAH.
During the past week the Montana
mill crushed 905 IONS OF ore effect
ing a saving Of SS per cent. In the
mine the workings were extended
200 feet.
390-foot level-The east drift
along the Triangle fault plane adj
vanced ten feet and the face shows
low grade quartz stringers. The
west drift on the Triangle vein adj
vanced nine feet along an ore body
that averages two and one-half feet
Of fair grade milling ore. The face
shows the vein somewhat pinched.
During the week the stopping or the
Triangle vein was confined TO the
western section. which shows two
and one-half feet of milling ore. The
cutting out OF a stope owe the west
drift has been continued up to a
width of thirty feet from the face
exposing an average of three feet of
milling ore. This section hae also
been timbered. The stope on the
Macdonald vein 100 feet west OF the
shaft, is being worked on two feet Of
mill ore.
465-foot level-The west drift on
the Triangle vein advanced eleven
feet on a vein averaging three feet
in width and carrying good milling
values. The face shows about FIVE
feet Of ore, but of a lower grade.
The west stope on the Triangle vein
produced a small tonnage of good
ore from an %eighteen-inch vein. The
stope on the Martha vein over the
level shows no change, two feet Of
good milling ore being exposed.
515-foot level-The west drift on
the South vein advanced twenty
three feet on fair milling ore and
the last few feet following the con-
tact, the vein having pinched out. A
fault was encountered about fifty
feet from the face and it is probable
that the vein has been displaced to
the north. a part of which Will be
determined by a short crosscut sent
out in that direction. The east drift
on the Martha vein advanced twenty
one feet on a good grade of milling
ore, the vein averaging two feet in
width. A raise on the vein seventy
five feet back from the face has been
started and is now up six feet, ex-
posing two and-one half feet of high
grade mill ore on the top. Stopping
on the Martha vein was confined tc
the central portion where the weir
averages twelve feet OF a fair milling
grade.
565-foot, intermediate level-Tht
drift east from the WINE on the
South vein advanced seventeen fee
and a connection was made with &
winze from the old workings. This
has now been cleaned out and drift
ing has been continued. West of the
winze the drift advanced seven fee.
showing two and-one half feet o
milling ore in the face. The drift
west from the south crosscut from
the Martha vein, along the quarts
vein encountered last week, advanced
fifteen feet. The ledge shows som,
, good spots of ore but the section Il
, very much broken up by a fault ant
, work has been suspended at tina
point and the crosscut sent aheat
again.
G15-foot level-The crosscut ives
> from the main south crosscut whicl
is being driven to connect with
q Wine from the Martha vein sen
down from the 515-foot level, wa
8 advanced forty-one feet during tn
r week and it is expected that the mex
forty feet will bring the face of tn
n crosscut to a point directly under
n meath the winze, where a raise wi
g be sent up and the connection made
{ There is nc change in the slopes o
the Macdonald vein below the leve
e and the slopes on the A b. X. an
o Martha veins above the level.
765-foot level-The crosscut mort
n was advanced seventeen feet and ha
now reached a point 164S feet fror
the shaft with no change in the fac,
