Operations through one compart
ment OF the Tonopah-B Belmont shaft
we're hung up this week for nearly
two days on account of the timbeis
bullying somewhat between the 800 and
400 foot levels, caused by the swelling
character of the ground at that point
which interfered with the operations OF
the cage in that compartment. Be
tween these two points tine contaet Dc
tween the rhyolite and later andesite
crosses the shaft, and the ground Is
shifting and wet, necessitating repairs
to be made quite often to the timDers.
Everything was put in first class shape
and full operations started last we'd
nesday. While the repairs were being
made to the compartment affected, d
portion of the force was kept at work
underground so that the delay did
not amount to much. The work OF

the 6O0-foot point, a distance Of "a u.
feet since sinking was resumed. From
present appearances, the shaft is about
through the wet belt, which is in the
~neighborhood of 100 feet wide, as prac-
tically no water is making from the
bottom. Sinking will be continued,
however, until this fact has been thor
oughly proven, when efforts will be
maze to collect the water and pump 1t
direct to the surface. From present in
dications it is thought that operations
with the churn drill will soon be COM
menced, in order to make connection
between the bottom of the shaft and
the crosscut on the 1,000-foot Level.
Operations are going steadily forward
On the levels from the present working
shaft and a great deal of new grouni
is being opened up. The most activity,
however, is going on below the 1000
foot level, where of late the best ore
bodies have been opened up. In addi-
ton to doing considerable lateral
work ON the 1,l00-foot level, the Wine
is being sent down below that poin;
in order to permit of the opening of
new levels at greater depth. There is
but little of Importance to note from
the older portions of the mine, the ore
bodies in the various slopes showing
about the same strength and values
as formerly. No effort is being male
to extract a large tonnage of ore, a
good portion Of the present shipments
to the mill coming from the develop
ment work, the largest slopes in the
mine, which are located east and west
of 1854 winze on the Mizpah vein, be
ing called upon very lightly, although
the ore body in these workings is be
tween 20 and 80 feet in width.

Another lot of bullion, weighing
about a ton, was sent forward to Sci
by s last Tuesday, being the result Of
the regular semi-monthly melt of the
cyanide precipitates, which was com
pleeted on Monday evening. TIT con
signment consisted of "a bars, weigh
ing in the neighborhood of 80 pounds
each. The regularity with which thess
bullion shipments 60 out twice every
month, in addition to from 100 to $50
tons of concentrates monthly, certainty
speaks volumes for the mine, which
has been a steady producer for the
past six years. In the earlier days OF
Tonopah the Montana was a shipper
of some of the richest ore sent out,
but since the completion OF its mot
ern 40-stamp mill the shipping ana
milling grade ores have been mixed
and worked at home most satisfactor-
lily. Barring the stoppages causSa
through mishaps to the big power plant
of the Nevada california Power Co. at
Bishop, all of the 40 stamps are kept
dropping continuously, the average
weekly tonnage treated being IN the
n~eighborhood of $50 tons, from which
a very satisfactory per sent. of extrac-
ton has been made. Owing to a con
siderable amount of the ore being
greatly oxidized, some trouble has been
experienced of late in obtaining the
percentage of extraction and working
the number of tons desired, but a few
slight changes were made and the diff
iculties have been overcome, with a
