REVIEW Of T0NOPAH MINES

The most important news that has
been announced in Tonopah re-
Gently was to the effect that the
ITonopah Extension Mining company
had cut the Murray vein at the
I1760-foot level.
As described in preceding reports,
the famous vein, which mas been
proven to the greatest depth at
which any ore has been found in
the entire portion of the state trib-
utary to the ,Tonopah district, was
found to have three separate and
distinct branches on upper levels,
the main section of the vein being
the middle branch, with narrower
veins in the footwall and hanging
wall.
The hanging wall branch was de-
.veloped to a depth midway between
the 1680-foot ana the 1760-foot
levels, but when the crosscut on
the bottom level reached the point
where the yein was expected to be
encountered, it was found that a
fault interviewed to cut the vein off
between the lowest level in the
mine and the bottom of the Wine.
Raising was started from the bot
tom level, and recently holed into
the winze, after which the main
south crosscut on the 1760-f0Ot
level was started up again, with the
purpose of exploring for the foot
wall branch.
The middle vein, at the point of
intersection by the crosscut on the
bottom level, is 4 feet wide, and is
composed of milling material. This
width does not compare with the
widths that were developed on up
per levels. but since the history of
development OF the vein at higher
elevations has been that on its
course to the west it widens to as
much as % feet, the comparatively
narrow width shown where it has
lust been encountered is not giving
the Extension officials any concern,
as there is every probability, in
deed. almost complete assurance,
that development work on the bot
tom level will succeed in demon
strating just as good widths and
values as have been shown above.
With the Murray vein proven at
the greatest depth of any mine in
Tonopah or other districts of South
ern Nevada. it is expected that
plans will be made within a short
time for the sinking of the Victor
shaft to still greater depth.
Belmont
Though still somewhat handi-
capped by a lack of sufficient skilled
miners to operate the machine drills
at the local mine, the Tonopah Bel
mont continues to report fairly sat
isfactory progress at its main work.
ing places, and in addition to the
work mapped out in the ordinary
routine of mining operations has
started development work at newer
points in the mine.
One of these places is on the
S0O-foot level, where two raises
have been started for the purpose
of developing the Mizpah Fault vein
on it's easterly extension from the
Desert Queen territory. A very sat
isfactory showing has been made in
one of the raises, the vein being
proven to have a width of five feet
at the time the report was made
yesterday morning. The other raise
is being sent up as an exploration
working at a point further along in
the crosscut. with the intention OF
picking up the vein at some dis
lance from the first mentioned
raise. Indications are good in the
exploration raise, a fine body OF
trachyte having been cut into since
the raise was started.
!. Work has also been resumed on
the 1440-foot level, by means OF an
intermediate crOsscut. which is be-
ing driven in "a ~northerly direction
for the purpose of prospecting for
hanging wall branch of the 1920
vein, which on other levels has per-
sistently yielded very good values.
At other places in the mine, moth
ing out of the ordinary in the way
of development occurred during the
past week, and satisfactory progress
was made at each of the headings
on the 700, 500, 1000, 100, 1900,
1900 and 1400-foot levels where de-
velopment and exploration work is
