TONOPAH DEVELOPMENTS
SET FORTH IN REPORTS
Burro No. 4

On the 540-foot level, one of the
pieces of development operations
was completed when the footwall
raise on the Burro No. 4 hanging
wall vein connected with the stone
workings on the vein at the next
higher level. This raise will now
be used in handling the ore from
the slope. The west drift from the
south cross-cut was discontinued,
as the ore at the face of the drift
got narrower at greater distance in
this direction was attained. A salts
factory tonnage has been developed,
the drift having opened up a width
OF about 2 feet for over 100 feet
along the vein.
The stope on the hanging-wall of
the Burro No. 4 vein was worked
as usual, and continued producing
ore.
On the 640-foot Level, raise $50
in the South Dipping vein just west
of the shaft still shows numerous
stringers, which carry values. The
management expects that both
raises mentioned will make connec-
tions with the workings on the
level above during the coming week.
There has been no change in the
drift in the foot-wall of the South
Dipping vein, which was put out the
usual distance in waste rock. The
footwall cross-cut in the Burro No.
q vein was discontinued and a raise
is now being driven to connect witt
it will be used for mining purposes,
afforded better facilities than are at
present available for breaking down
the ore in the vicinity. No new or
unusual development was made in
south cross-cut 610 west of the
shaft, outside of the regular foot
age. The face of the cross-cut is
still in %trachyte. Raise 644, in the
footwall of the Burro No. 4 vein,
however, encountered a promising
streak Of quartz, about 2 feet in
width, and while it is at present of
low grade it offers an encouraging
field for further development. 1t
is thought that the discovery may
be a footwall streak of the Burro
No. 4 vein.
There has been little or no
change shown in the stope work
ings, either on the Burro No. 4 vein
or the South Dipping vein. The
stope on the first mentioned vein
was prosecuted as usual on about 4
feet Of milling grade ore, while that
on the South Dipping vein is adj
Vancing against a face of 6 to 8
feet of mill ore.
Mizpah Claim
At the Mizpah claim, on the 400
foot level, stopping underhand from
the level was carried on without in
te%rruption, and still exposes a 3
to 4-foot width of milling ore.
On the 500-foot level, there has
been no elimination of the excellent
indications disclosed last week in
the north cross-cut from the drift
west of the shaft. Considerable
quartz continues to appear in the
cross-cut as it is extended near the
nCrth-south fault, occasional values
being found. The stope in the YER
teal vein has shown a decrease in
the width of the oreshoot. which
now measures 2 feet as against the
3-foot face reported previously. The
ore continues to be of good milling
grade.
On the 600-foot level, west d.
GOA was extended at the usual rate
Of speed in the West End rhyolite,
without any change having appear
ed. The stope on the Mizpah vein
still shows between 2 and 3 feet
OF milling grade and the regular
amount of ore was extracted at this
point.
At the Sandgrass claim, on the
1140-foot level, there was no de-
velopment work undertaken during
the week. Henceforth, now that the
shaft has been sunk to this level.
lateral work will be prosecuted with
greater FACILITY as ore and rock
can be handled directly through the
material. as in former times.
On the 1200-foot level, the west
drift on the Breccia vein has under
gone no particular change since
the previous report was issued. The
face of the drift still shows a 2 to
3-foot width of quartz, which is
barren of values. The raise from
the east drift on the Upper Sand
grass vein connected with the level
above, and is now available for
mining purposes. A new west drift
was started on the Upper Sand
grass.
