ToNoPAH MINING.

The workings of the Tonopah Min
ing company were extended S91 feet
during the week, this amount being
divided in drifting, prosecuting and
sinking. OF the total the Mizpah is
credited with 269h feet, the Silver
Top 100 feet and the Red Plume
twenty-one and one-half feet. The
shaft ON the latter workings was
sunk nine feet and is now down a
total distance Of 522 feet from the
surface. The progress was somewhat
slow in the Mizpah shaft owing to the
water and only thirteen feet of pro-
gress was made, making the depth Of
the shaft 1909 feet. The water has
been. maintaining a regular flow Of
late and is averaging about sixty gal
Ions a minute. The diamond drill on
the 740-level of the Silver Top ad-
vanced twenty-five feet and is now
down a depth of 662 feet from this
level, or a depth of 1902 feet below
the surface.
In the Silver Top workings there
has been practically no change no.
ticed in the various portions of the
mine. Superintendent Blackburn has
started some footwall prosecuting
and raising on the 240 and $40 foot
levels in order to get under the Hat
veins in the slopes in the westerly
end of these levels.
Work has been resumed on the
640-foot level in the drift that will
follow up the vein for about 200 feet
and then a raise will be sent up 10
order to tap an ore body that exists
under the 540-level.
20O-foot level, Mizpah-The no III.
west drift along the Mizpah fault has
gone into ore again after passing The
faulting that shifted the main fault to
the north. This body shows up abo {
two or three feet of good milling ore.
Work was resumed in the first cross
cut north from the west drift which
will be driven to the company's side
line.
30O-foot level-The erosscut from
the west workings will be driven orr
to the south to get under the Burro
NO. | vein that was opened up on the
second level. This will necessitata
about 200 or 800 feet Of drifting and
1t is thought that when the vein IS
encountered it will be of a fair mill
ing grade of ore.
4OO-foot level-The northwest
drift along the Mizpah fault has en-
countered ore that is thought to he
the shoot that shows on the 200 and
SOO-foot levels. 1t is of a fair mill
ing grade and will average about
three feet in width. From the east
workings about 600 feet from the
smart a crosscut has been started
south for the purpose of prospecting
a block OF ground that has not been
opened up before. This crosscut
started out in a peculiar formation of
rhyolite-dacite. 1t will test the for
nation and also look for parallel
stringers that are thought to exist.
0OO-foot level - The northwest
drift along the Mizpah fault has
reached the property line where on
erations have ceased. No ore was en-
countered in this drift. The cross
cut along the West End line has
reached a point about opposite the
workings Of that property and a con-
nection will soon be made for better
ventilation. The crosseut to the soutb
In this region will be continued az
several stringers of ore have been emf
which will be prospected later.
o0O-foot level-The crosscut thar
IS being driven to connect with the
lied Plume shaft, is making good {
progress and will make the connec- Z
ZION after travelling about forty feet 7
more In the shaft at this level the t
work OF cutting out a station is 90 L
ing on which has slightly retarded
the sinking. :
